Run a JSP from within a help plugin [message #623572]

Hi all,

I'm searching for a way to incorporate a JSP in a help plugin.

I assume that there is some extension point that will allow me to instruct the jetty JSP server to compile .jsp files within my plugin, but so far I've been unsuccessful finding this information in the docs. Any pointers at all would be much appreciated.

Thanks,
Doug

For what it's worth, I found a bug report (opened by me, go figure) referring to this behavior. The resolution suggests it is possible to compile and run a .jsp from a help plugin. The bug is

https://bugs.eclipse.org/bugs/show_bug.cgi?id=214946

I cannot, however, seem to make this work as described in the resolution description.

I'm using Eclipse 3.4.2, which is the only difference I can spot between the plugin description in the bug report and my own plugin.

It sounds as though you are close - does your plugin have dependencies to org.eclipse.equinox.jasper and org.eclipse.equinox.jasper.registry?

Got it.

The necessary change was to add a slash to the end of the servlet class attribute. The plugin.xml now contains the following:

<extension point="org.eclipse.equinox.http.registry.servlets">
<servlet
alias="/jsp/*.jsp"
class="org.eclipse.equinox.jsp.jasper.registry.JSPFactory:/ ">
</servlet>
<serviceSelector
filter="(other.info=org.eclipse.help)">
</serviceSelector>
</extension>

Note the slash at the end of org.eclipse.equinox.jasper.registry.JSPFactory:/

I don't quite understand why this is necessary, but adding it seemed to do the trick.

Now, on to my next challenge: getting access to Java functions defined in other plugins. Most notably org.eclipse.help.webapp.
