Problems with RCP Help in 3.3 [message #469650]

Migrated to 3.3 and my RCP help system continues to work on OSX platform but
breaks on Win32 with an error involving index.jsp. I noted the previous
thread about this, and my old help plugin requested Tomcat, etc. so I
changed this to only depend on org.eclipse.help.webapp and
org.eclipse.help.ui and I have my run configuration check for optional
dependencies. However, my error persists, and is an HTTP ERROR: 500 unable
to compile class for JSP, RequestURI=/help/index.jsp (and says powered by
Jetty, etc.)

When I examine the plugins in the exported product, Tomcat is still present,
which is disturbing since it is not checked off as a required plugin in my
run configuration, and I wonder if this is part of my problem.

Interestingly, if I select dynamic help, the entire system works inside that
window, with full access to all content, etc. Just does not work when I
select "Help Contents" and an external browser is invoked.

The documentation about Help continues to indicate the need to add the
larger number of plugin dependencies and I am working off the paper from
September by Goldthorpe and Archer.

Thanks in advance for any help you might be able to provide.

Nice to see that someone is reading our article.

If the help view is working but not the browser then this indicates that
the help server is starting OK but there seems to be a problem loading
the jsps which form the webapp. The help view does not use any jsps.

I can think of a couple of possibilities, one is the jasper compiler is
not being included in your RCP, the other is that the jsp file is not
found.

When you start Help/Contents do you see multiple frames in the browser
or just one frame with the message about being unable to compile index.jsp?

Are you able to perform a Help/Search and find results when you perform
a search?

Are there any errors written to the log?

As for the tomcat plugin if you remove it from the list of plugins in
your product configuration I would not expect it to get pulled in as a
dependency of any other plugin. I'm not sure why you are seeing this.

I use a subset of the help system plug-ins to make a standalone help
system running on Windows XP. I know that my situation is not strictly
an RCP situation, but maybe you can use this to compare.

The subset of plug-ins I find that is needed to run the standalone help
system on Windows XP is:
org.eclipse.core.runtime.compatibility.registry
org.eclipse.equinox.launcher.win32.win32.x86
com.ibm.icu
javax.servlet.jsp
javax.servlet
org.apache.commons.el
org.apache.commons.logging
org.apache.jasper
org.apache.lucene.analysis
org.apache.lucene
org.eclipse.core.contenttype
org.eclipse.core.expressions
org.eclipse.core.jobs
org.eclipse.core.runtime.compatibility.auth
org.eclipse.core.runtime
org.eclipse.equinox.app
org.eclipse.equinox.common
org.eclipse.equinox.http.jetty
org.eclipse.equinox.http.registry
org.eclipse.equinox.http.servlet
org.eclipse.equinox.jsp.jasper.registry
org.eclipse.equinox.jsp.jasper
org.eclipse.equinox.launcher
org.eclipse.equinox.preferences
org.eclipse.equinox.registry
org.eclipse.help.base
org.eclipse.help.webapp
org.eclipse.help
org.eclipse.osgi.services
org.eclipse.osgi
org.eclipse.update.configurator
org.mortbay.jetty

I have some older version doc plug-ins, so I keep the
runtime.compatibility plug-in to handle those.

Hello,

Even I face the same problem as mentioned by Michael. Following is the list
of answers to Chris's qeustions:

When you start Help/Contents do you see multiple frames in the browser
or just one frame with the message about being unable to compile index.jsp?

I can see only one frame which says "HTTP ERROR: 500
Class org.apache.jasper.servlet.JspServlet does not implement the requested
interface javax.servlet.ServletRequestURI=/help/index.jspPowered by
Jetty://"> Are you able to perform a Help/Search and find results when you
perform
> a search?

Yes, it works well while performing a search, the problem comes only when I
click Help contents under Help menu

> Are there any errors written to the log?

It is as follows:

Mar 31, 2008 4:10:48 PM org.mortbay.jetty.servlet.ServletHandler handle

WARNING: Error for /help/index.jsp
