Developing Web Views for VMware vCenter
Orchestrator
Developing Web Views for VMware vCenter Orchestrator provides information about developing Web views for
VMware® vCenter Orchestrator.
Orchestrator Web views are Web 2.0 frontends that allow users to access Orchestrator workflows and
objects in the Orchestrator inventory by using a Web browser rather than by using the Orchestrator client.
Orchestrator provides a standard Web view that users can use to run workflows, called weboperator. The
weboperator Web view provides end users with browser access to all of the workflows in the library, that
they can run on all of the objects in the inventory.
The Web components which Orchestrator provides can be used to develop custom Web views.
Intended Audience
This information is intended for Web designers and developers who want to create or customize Web front
ends for the Orchestrator processes, using the Web 2.0 technologies.

Web View Overview1
A Web view is a package of Web pages, style sheets, icons, and banners that represent a complete Web site.
Web views can contain special Java Web Components (JWC) that add Orchestrator functions to the pages of
the Web views. For example, you can add components that allow users to run workflows from a browser.
Orchestrator Web views update content dynamically without obliging users to reload complete pages.
Orchestrator provides a library of Tapestry Framework 4.0 components to help you build customized Web
views to access Orchestrator functions from a Web browser. Tapestry components provide access to objects
in the Orchestrator server, such as the workflows in the library and the virtual machines in the inventory.
You can also insert Dojo 0.4.1 components into Web views.
Orchestrator provides a Web view template that you can use as the basis for developing Web views. The
Web view template contains skeleton HTML pages and Web view components that you can extend and
adapt. You can also export existing Web views to use as templates that you can adapt to create new Web
views.
You typically create or modify the pages of a Web view externally by using Web design tools. Creating or
modifying Web pages independently of Orchestrator allows you to separate the Web design process from
the process of developing Orchestrator Web view components. You import the Web view pages and
components into the Orchestrator server and complete the process of creating the Web view in the
Orchestrator client.
VMware, Inc.
Developing Orchestrator Web views can require knowledge of some or all of the following Web
development technologies and standards. For documentation about the different technologies, consult the
Web sites of the organizations that maintain the standards.
Cascading stylesheets (CSS). See http://www.w3.org/Style/CSS/.

Weboperator Web View2
Orchestrator provides a standard Web view called weboperator that allows users to run workflows from a
browser.
The weboperator Web view provides an example of the orchestration functions that Web views can provide
to end users in browsers, without requiring that those users use the Orchestrator client.
Start the Weboperator Web View
You start the weboperator Web view from the Orchestrator client.
Procedure
1From the drop-down menu in the Orchestrator client, select Administer.
2Click the Web Views view.
The weboperator Web view and any other Web views that you have imported into Orchestrator appear.
3Right-click weboperator and select Publish.
4Open a browser and go to http://orchestrator_server:8280.
In the URL, orchestrator_server is the DNS name or IP address of the Orchestrator server, and 8280 is the
default port number where Orchestrator publishes Web views.
VMware, Inc.

Developing Web Views for VMware vCenter Orchestrator
You can use the weboperator Web view to run workflows on objects in your inventory from a Web browser
rather than from the Orchestrator client.
What to do next
If you only need a Web view to access the inventory and run workflows, the standard weboperator Web
view should meet your requirements. If you require more complex functionality from a Web view, you can
use the Web components and default Web view template that Orchestrator provides to develop custom Web
views.

Web View Development Tasks to
Perform in Orchestrator3
You create the Web pages and Web view components that form an Orchestrator Web view by using Web
development tools. You also use the Orchestrator client and configuration interface to perform many of the
steps of Web view development.
When you develop Web views, you use the Orchestrator client to perform tasks such as creating skeleton
Web views, declaring objects in the Orchestrator server as Web view attributes, exporting and importing
files to and from working directories, and creating and using templates to create other Web views. You set
the Orchestrator server to Web view development mode by using the Orchestrator configuration interface.

You can edit and adapt the Web view files by using Web development tools.
NOTE To preview the Web view from the working folder while you develop it, set the Orchestrator server
to Web view development mode.
Configure the Server for Web View Development
During the Web view development process, you can configure the Orchestrator server to publish the Web
view from a working folder rather than from the Orchestrator server.
When the server runs in development mode, you can preview the Web view as you develop it, without
having to import it to the Orchestrator server to view it. You set the Orchestrator server to Web view
development mode in the Orchestrator configuration interface.
NOTE Because Orchestrator publishes Web views from the working folder, you cannot access Web views
that you have not exported to the working folder when the server is in development mode.

With Web view attributes, you can pass objects to Web view components. The functions that the Web view
components define act on these objects to perform the orchestration actions that you run from the Web view.
A Web view attribute can be an object of any type that the Orchestrator API supports. For example, a Web
view attribute can be a VC:VirtualMachine object. A Web view component can define a function that
requires this object as an attribute. For example, when a user clicks a button in a Web view, a Web view
component associated to that button runs a workflow that starts a virtual machine. A Web view attribute
provides the virtual machine object to the workflow that the Web view component starts.

File Structure of a Web View4
When you develop a Web view, you must save the collection of Web pages and Web view components that
comprise the Web view to a working folder. The Web view working folder must conform to basic filenaming and file-structuring rules.
You can name the working folder in which you develop the Web view pages and components any name
that is appropriate. The working folder must contain the following file and folder at its root.
Table 4‑1. Web view file structure
FileDescription
<WebView_Folder>\default.html
<WebView_Folder>\components\
IMPORTANT If you create more than one Web view to run in the same Orchestrator server, you must save the
Web view components in subfolders inside the components folder, to avoid conflicts between identically
named components. Alternatively, create all Web view components with a unique name.
The home page of the Web view. All Web views must
include a default.html file at the root of the working
folder.
Contains the JWC files and the associated HTML templates
of the Web view components. The components folder must
be at the root of the working folder.
VMware, Inc.
The default.html file and the components folder are the only mandatory elements that a Web view must
contain. You can add other files and folders in the Web view folder and organize the files and folders in any
way. You can include HTML files that are not Web view component templates anywhere in the Web view
folder.

Web View Components6
Web view components add Orchestrator functions to Web pages. For example, you can add Web view
components to Web pages that allow users to run workflows from a Web page in a browser.
You build Orchestrator Web views by adding JWC components to HTML Web pages. Orchestrator provides
a library of JWC Web view components that add predefined orchestration functions to Web views. The JWC
Web view components that Orchestrator provides conform to the Tapestry Framework 4.0 standard.
In addition to the library of Web view components that Orchestrator provides, you can use every standard
component from the Tapestry Framework 4.0 in Web views.
Tapestry Web View Components on page 25
n
With the Tapestry Web view components in the Orchestrator Web view component library, you can
add orchestration functions to Web views. The Tapestry Web components in the Orchestrator library
define actions that access objects in the Orchestrator server.
Creating Tapestry Web View Components on page 26
n
With Orchestrator, you can create custom Tapestry Web view components to perform orchestration
functions from Web pages. A Tapestry Web view component conforms to the Tapestry Framework
standard version 4.0.
Orchestrator Tapestry Component Library on page 32
n
Orchestrator has a library of Tapestry components that you can reference in Web views. You can also
use all of the components that the Tapestry Framework 4.0 standard defines.
Tapestry Web View Components
With the Tapestry Web view components in the Orchestrator Web view component library, you can add
orchestration functions to Web views. The Tapestry Web components in the Orchestrator library define
actions that access objects in the Orchestrator server.
The Tapestry Web view components that Orchestrator provides add functions to Web views such as
obtaining and displaying the properties of an object in the server, starting workflows, or obtaining
information from the user.
You add Tapestry components to a Web view by adding a jwcid attribute to an HTML tag in a Web page.
When you reference a Web view component, you prefix the name of the component with the @ character.
Certain Web view components require you to set additional properties when you set the jwcid attribute.
VMware, Inc.

Developing Web Views for VMware vCenter Orchestrator
Add a Tapestry Component in an HTML Page
You add Tapestry components to a Web view by adding a jwcid attribute to an HTML tag in a Web page.
The jwcid attribute references a Web view component.
You can add a jwcid attribute to any HTML tag. You can add references to components from the
Orchestrator Web view component library, to components from the Tapestry Standard, or to custom
components that you create.
Prerequisites
Create a Web view in the Orchestrator client and exported its contents to a working directory.
Procedure
1Open an HTML page of a Web view in an HTML editor.
2Add an arbitrary tag to the HTML file, in the position at which the Web view component is to appear in
the page.
For example, add the following arbitrary tag in the appropriate position in the HTML file:
<vco>
3Add to the arbitrary tag a jwcid attribute that references a Web view component.
For example, the following jwcid attribute adds the vco:DisplayProperty component from the
Orchestrator library to the Web view.
<vco jwcid="@vco:DisplayProperty">
The vco:DisplayProperty component obtains and displays the properties of an object that is in the
server in the Web view.
4Add the additional properties that the component requires to the arbitrary HTML tag.
For example, the following Web view component displays the MyVirtualMachine virtual machine Name
property in a Web view.
You added a reference to a Web view component to a Web page in a Web view.
Creating Tapestry Web View Components
With Orchestrator, you can create custom Tapestry Web view components to perform orchestration
functions from Web pages. A Tapestry Web view component conforms to the Tapestry Framework standard
version 4.0.
A Tapestry Web view component must contain a component specification file and a component template.
IMPORTANT The Tapestry component template file and the component specification must have the same
name. For example, if you name a component template MyComponent.html, you must name the associated
component specification MyComponent.jwc. Web view components that you use in different Web views that
run in the same server must have unique names.
26 VMware, Inc.
Chapter 6 Web View Components
You must save the component files in the components folder in the Web view file structure. If you create
subfolders in the components folder, you must specify the full path to a component when you set the jwcid
attribute in HTML pages. For example, if you include a MyBorder component in a
<WebView_Folder>\components\layout\ subfolder, you must set the jwcid attribute, as the following example
shows:
<div jwcid="@layout/MyBorder">
You can precede the @ character with a unique identifier. With the unique identifier, you can reuse the class
throughout the HTML page, by referencing the unique identifier.
In the following example, the component is Border and the unique identifier is myBorderComponent.
<div jwcid="myBorderComponent@MyBorder">

Accessing Server Objects from URLs7
You can add URLs to Web view pages to access objects in the Orchestrator server, without having to
implement a Web view component. For example, you can add URLs to Web view pages that run an action
in the Orchestrator server or URLs that retrieve resource elements from the Orchestrator server.
Running Actions from URLs on page 43
n
Running actions from URLs rather than by implementing Web view components allows you to run
operations directly in the Orchestrator server without requiring any input parameters from the Web
view user. Running actions from URLs also allows you to define how to process the action results.
Accessing Resource Elements from URLs on page 45
n
Workflows and Web views can require as attributes objects that you create independently of
Orchestrator. To use external objects as attributes in workflows or Web views, you import them into
the Orchestrator server as resource elements.
Running Actions from URLs
Running actions from URLs rather than by implementing Web view components allows you to run
operations directly in the Orchestrator server without requiring any input parameters from the Web view
user. Running actions from URLs also allows you to define how to process the action results.
VMware, Inc.
When you run a workflow from a Web view component, the Web view prompts you for input parameters
before it runs. Web view components also apply formatting to any data they receive from the server. If you
retrieve objects from the server from a URL rather than from a Web view component, you can apply your
own formatting or processing to the data that the URL retrieves.
For example, certain actions return JavaScript Object Notation (JSON) data. If you call such an action from a
URL in a Web view, you can write Ajax functions to process and format the action results. Similarly, if the
action returns an object from the Orchestrator server, you can write JavaScript functions to act on this object
in the Web view.
To run an action from a URL in a Web view, you must declare that action as a Web view attribute and
reference the attribute in the URL.
Web views access actions that you have defined as Web view attributes at the following URL:
To avoid hard-coding the orchestrator_server address into the URL, you can provide relative paths to the
action that start from the directory below the Web view URL folder, as the following path shows:
Developing Web Views for VMware vCenter Orchestrator
Setting Action Parameters in a URL
You pass input parameters to the action by setting the actionParameters property in the URL. Depending
on the action, you might need to declare the input parameters for the action as Web view attributes. If the
action parameters are Web view attributes, you must prefix the Web view attribute name of the parameter
with attribute:, as the following example shows.
You can use a URL to run an action that returns its results as a MimeAttachment file. You provide the name
and type of the file to which to write the results in the URL. You must define the action to run as a Web view
attribute.
Web views access actions that you have defined as Web view attributes and obtain their results as
The filename.file_extension file you specify for the output file can be any type of file. If you set the
optional mimeType property, the file type must be a valid MimeAttachment file, for example an EML or PDF
file.
To avoid hard-coding the orchestrator_server address into the URL, you can provide relative paths to the
action that start from the directory below the Web view URL folder, as the following path shows:
The preceding example URL performs the following tasks:
Runs an action that you have declared as the Web view attribute generateReport, which returns a
n
MimeAttachment object.
Creates a PDF file called annualReport.pdf
n
Returns the PDF file
n
Run an Action from a URL
You can add URLs to Web view pages to run actions in the Orchestrator server. Running actions by using
direct URLs rather than by using Web view components allows you to specify the parameters with which to
run the action in the URL, and allows you to provide your own formatting to the action results.
Prerequisites
You have created a Web view in the Orchestrator client and have Web view page in which to insert a URL to
run an action.
Procedure
1From the drop-down menu in the Orchestrator client, select Administer.
2In the Web views view, right-click the Web view to which to add the URL and select Edit.
You must unpublish a running Web view to edit it.
3Right-click in the Attributes tab of the Web view editor and select Add attribute.
44 VMware, Inc.
Chapter 7 Accessing Server Objects from URLs
4Create a Web view attribute, of type Action with the value set to the action of your choice.
For example, name the Web view attribute MyAction.
5Create Web view attributes for each of the input parameters that the action requires.
For example, name a Web view attribute ActionParameterAttribute.
6Click Save and close to exit the Web view editor.
7Open the HTML page in which to insert the URL in an HTML editor.
8Add a link to https://orchestrator_server:
8280/vco/vmo/web_view_url_folder/system/vmo/pages/action.html at the appropriate place in the
HTML file.
Add a relative link to the action URL, that starts below the Web view URL folder value, rather than
hard-coding the address of the Orchestrator server in the URL, as the following example shows:
<a href="./system/vmo/pages/action.html?action=myAction
&actionParameters=attribute:ActionParameterAttribute
&actionParameters=action_parameter_value">
Click here to run an action</a>
The URL uses the Web view attributes you set in the Orchestrator client to start the action myAction and
to set the ActionParameterAttributeparameter. The second parameter, ActionParameterValue, is not a
Web view attribute so you add the parameter value directly in the URL.
You added a link to run an action from a URL. When users click the link in the published Web view, the
action runs with the parameters you reference in the URL. JavaScript functions that you define can process
the results of running the action.
Accessing Resource Elements from URLs
Workflows and Web views can require as attributes objects that you create independently of Orchestrator.
To use external objects as attributes in workflows or Web views, you import them into the Orchestrator
server as resource elements.
You can add URLs to Web view pages to retrieve resource elements from the Orchestrator server. You can
then add JavaScript functions to the Web view to process the resource elements. To access a resource
element from a URL in a Web view, you must declare that resource element as a Web view attribute and
reference the attribute in the URL.
Web views access resource elements at the following URL:
To avoid hard-coding the orchestrator_server address into the URL, you can provide relative paths to the
action that start from the directory below the Web view URL folder, as the following path shows:
Resource elements are files that are imported into the Orchestrator server for use by Orchestrator
applications. By accessing a resource element from a URL in a Web view, you make that resource element
available to processing that you define in the Web view.
Objects that workflows and Web views can use as resource elements include image files, scripts, XML
templates, HTML files, and so on. Any workflows or Web views that run in the Orchestrator server can use
any resource elements that you import into Orchestrator.

7Add a link to https://orchestrator_server:
8280/vco/vmo/web_view_url_folder/system/resources/attributes/resource_attribute_name.att at
the appropriate place in the HTML file.
Add a relative link to the resource element URL, that starts below the Web view URL folder value,
rather than hard-coding the address of the Orchestrator server in the URL, as the following example
shows:
<a href="./system/resources/attributes/MyImage.att">
Click here to obtain an image</a>
The URL uses the Web view attribute you set in the Orchestrator client to obtain the resource element in the
Web view.

Create a Simple Web View Using the
Default Template8
The easiest way to create a Web view is to use a template. Orchestrator provides a default Web view
template to help you create Web views.
You can use the default template to create a simple Web view called Virtual Machine Manager. You can find
a ready-made version of the Virtual Machine Manager sample Web view in the bundle of Orchestrator
examples.
NOTE If you install the Virtual Machine Manager Web view from the Orchestrator samples bundle, you
must edit the vmFolder attribute to point to a virtual machine folder in your vCenter Server before you
publish the Web view.
