In step 4 on page 44, you added a servlet definition to GDesktop for something called the GASAssigner servlet.
This tells your browser which script to show based on Assignment Rules which you specify.
Please look at instructions "Genesys Agent Scripting Project Book" on page 45 - you need to give the project book the URL of the GASAssigner Servlet (as a browser would need it), e.g.:
[font=Courier]<servlet-mapping>
<servlet-name>GASAssignerServlet</servlet-name>
<url-pattern>/GASAssigner</url-pattern>
</servlet-mapping>[/font]
...the [font=Courier]<url-pattern>[/font] defines how a browser should access this servlet - you are configuring the WEB.XML file for the /gdesktop/ app so:
[u]http://yourserver:8080/gdesktop/GASAssigner[/u] is the Assigner Servlet URL... Put this URL into the Step 2 config from page 45/46.
For the default project book URL, put the URL where the GAS Scripts will be accessed by a browser after they are compiled (NOT in the same Tomcat instance as GDesktop!!), e.g.:
[u]http://yourserver:[b]8090[/b]/MyScriptProject[/u]
Note: In my install I had to compile Agent Scripts to the root folder of Tomcat - I could not use a sub-directory.
Hit the "Deploy Rules" button - If the URL is configured OK, you should find a WWGAssignRules.xml file in the .../webapps/gdesktop/ folder.
Hope that helps,
