Running Minimal Standalone [message #523338] Thu, 25 March 2010 19:31 Go to next message

Hi,

I followed the instructions for running a minimal infocenter standalone.

Platform Plug-in Developer Guide > Programmer's Guide > User assistance support > Help > Configuration/setup > [Optional] Installing a minimal stand-alone help system

When I try to start the infocenter using the minimal plugins directory, I get the following exception:

java.lang.Exception: Plugins directory /home/ole/Documents/help/eclipse/plugins does not contain a valid startup jar.  Pass a correct -eclipsehome option
        at org.eclipse.help.internal.standalone.Eclipse.getStartupJar(Eclipse.java:182)
        at org.eclipse.help.internal.standalone.Eclipse.prepareJavaCommand(Eclipse.java:76)
        at org.eclipse.help.internal.standalone.Eclipse.prepareCommand(Eclipse.java:48)
        at org.eclipse.help.internal.standalone.Eclipse.run(Eclipse.java:87)


Is it possible to point the infocenter at a plugins directory that is different from the plugins directory contained in the eclipse folder? Something like -helpPluginDirectory /home/ole/help/onlyHelpPlugins

TIA,
- Ole

Standalone help uses the eclipse launcher and needs to know where to find that. You can specify the location using the eclipsehome parameter. Below is the documentation for this parameter

-eclipsehome eclipseInstallPath - specifies Eclipse installation directory. This directory is a parent to "plugins" directory and eclipse executable. The option must be provided, when current directory from which infocenter is launched, is not the same as Eclipse installation directory.

Hi,

I tried changing the startup line to this:
java -classpath /home/ole/Documents/help/eclipse/plugins/org.eclipse.help.ba se_3.4.v20090526.jar org.eclipse.help.standalone.Help -command start -noexec -eclipsehome /home/ole/Documents/infocenter/eclipse -port 46000 -host 127.0.0.1

And now it runs, but it when I look at the URL http://127.0.0.1:46000/help/index.jsp all the help from the eclipsehome location is included in the infocenter. So it seems that instead of reading the help content from the classpath setting, it is now reading it from eclipsehome.

Is there a way to start up a minimal eclipse infocenter with just the minimal jars and only the help plugins that are user deployed? Also is this a "Documentation bug?". My understanding of the documentation is that the minimal recreated eclipse plugin directory should have had everything needed to run the infocenter?

Thanks again,
- Ole

I tried the steps in the documentation and also could not get this to work. There is a bug open on this issue, https://bugs.eclipse.org/bugs/show_bug.cgi?id=287117 - I will follow up in the bug report once I have figured out what the problem is.

Super - I'll keep an eye on the bug reports and test out fixes. Please let me know if there's anything else I can do to help (Update documentation, etc.). Also, I was thinking that this could be made simpler by adding a helpPluginsHome parameter. Then the documentation would just say this:

Run eclipse standalone passing the helpPluginsHome parameter pointing to the workspace with the help plugins.

I'm running Fedora, and would love to be able to start the infocenter like this:

java -classpath /usr/lib64/eclipse/plugins/org.eclipse.help.base_3.4.v200905 26.jar org.eclipse.help.standalone.Help -command start -noexec -helpPluginsHome /home/ole/workspace -port 46000 -host 127.0.0.1

If this sounds like a good idea I'll add the notes to a bugzilla ticket, or start a new one, which ever is better.

Thanks,

Hi, this is slightly related.

I need to run a minimal standalone without the need for start and stop scripts. In other words, I want users to be able to click the cross in the top-right of the browser and for it to close cleanly, including all processes, as if the stop script had been invoked. Does anyone have a suggestion for how to achieve this?

Hi,

The help system is packaged as a WAR file now:

http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse .platform.doc.isv/guide/ua_help_war.htm

So you could deploy as described, and then just add the capabilities for starting and stopping. For an example see the Tomcat Manager Web App. It can start and stop deployed web apps per the manager page by clicking on start/stop links.

HTH,
