Calling help from a different RCP app [message #623974]

Hello,
I have created a help contents plugin. I can bring up the help system from a view toolbar button successfully if I am running my own RCP stand-alone application using the following code:
...
PlatformUI.getWorkbench().getHelpSystem().displayHelpResourc e( "/gov.usgs.jem.model.spoonbill.help/html/toc.html");
...

But I have also exported my view plugins to be run from someone else's RCP application. Everything works fine except the help is NOT opening or doing anything when calling the line above.

The following line also returns true if that helps (which gives me a little hope): PlatformUI.getWorkbench().getHelpSystem().hasHelpUI()

Would anyone have any suggestions???
Thanks for any help! :)

Most likely the RCP app does not include all of the plug-ins required by help. Did you take a look at this Eclipse corner article on adding help to an RCP application?

Thanks so much Chris! :) Definitely made me look closer at the plugins being packaged with my non-rcp export.

Just in case anyone else has this issue, seems I was missing the following plugins that the help needs...

org.apache.jasper_5.5.17.v200806031609.jar
org.eclipse.equinox.http.jetty_1.1.0.v20080425.jar
org.eclipse.equinox.http.registry_1.0.100.v20080427-0830.jar
org.eclipse.equinox.http.servlet_1.0.100.v20080427-0830.jar
org.eclipse.equinox.jsp.jasper.registry_1.0.0.v20080427-0830 .jar
org.eclipse.equinox.jsp.jasper_1.0.100.v20080427-0830.jar
org.eclipse.help.webapp_3.3.101.M20080805_34x.jar
org.eclipse.osgi.services_3.1.200.v20071203.jar
org.mortbay.jetty_5.1.14.v200806031611.jar
org.apache.commons.el_1.0.0.v200806031608.jar
org.apache.commons.logging_1.0.4.v20080605-1930.jar

I added them to my feature (which my product was based on) using the Plug-ins tab. Maybe there's another way I should have added them. Not sure. Anyway, just thrilled that it's now working. Woohoo!
