Exercise

Set up a development environment

1. In the navigation pane, click Setup.
2. If you don't see an entry called Develop, then:
   • Set up Developer Privileges

Create a JSP Page

1. Click Designer > Logic > Pages > [New Page]

Note: If this is the first development activity to occur, you may see an error message like the following at the top of the screen: To create a new class, page, or execute Java code in Data Policies, namespace needs to be set in Company Information. Click here ... The link takes you to the Developer Configuration page, where you can specify your organization's namespace--typically, the company name or an abbreviation of it that corresponds to the company URL. (The lab exercises use "demo".)

2. Enter the page name: HelloWorld.jsp
   Note: It is necessary to add the .jsp extension when specifying the page name.
3. Add content for the page: <syntaxhighlight lang="java">

   Hello World!

   </syntaxhighlight>

4. Click [Save]

Visit the page to confirm that it exists

• In your web browser, visit https://{platform}/networking/pages/HelloWorld.jsp, substituting your platform URL for "{platform}".

The page you created appears.
