Problem integrating equinox transforms (xslt) [message #119767]

Mon, 20 October 2008 06:39

Eclipse User

Hi everyone,

I am currently trying to integrate equinox transforms as described on
http://wiki.eclipse.org/Equinox_Transforms. For my sample application this
works perfectly but not when I try to integrate it into my real
application.

What I'm trying to do:

I'm trying to disable menu contributions from org.eclipse.ui.ide. The
"Working sets"-item from the "Window" menu would be an example. Therefore
I'm trying to integrate equinox transforms as described in the wiki.

What I've done so far:

1. I created a new Plugin containing an Activator including the following
code

Properties properties = new Properties();
properties.put("equinox.transformerType", "xslt");
registration = context.registerService(URL.class.getName(),
context.getBundle().getEntry("/transform.csv"), properties);

2. I created the transform.csv an a xsl-stylesheet

3. I added the new plugin to my feature

4. I created a config.ini file containing the following

#Product Runtime Configuration File

osgi.splashPath=platform:/base/plugins/de.tecis.excalibur.e2
eclipse.product=de.tecis.excalibur.e2.product
osgi.bundles=org.eclipse.equinox.transforms.xslt@1:start,de.tecis.excalibur.equinox.transforms@1:start,org.eclipse.equinox.common@2:start,org.eclipse.update.configurator@3:start,org.eclipse.core.runtime@start
osgi.bundles.defaultStartLevel=4
osgi.framework.extensions=org.eclipse.equinox.transforms.hoo k

The plugin de.tecis.excalibur.equinox.transforms is the newly created
plugin.

The equinox transforms service seems to start correctly when I comment the
following line from config.ini
osgi.framework.extensions=org.eclipse.equinox.transforms.hoo k because the
osgi console gives me the following

0 ACTIVE org.eclipse.osgi_3.3.2.R33x_v20080105
Fragments=68
1 ACTIVE de.tecis.excalibur.equinox.transforms_1.4.0.rc3
68 RESOLVED org.eclipse.equinox.transforms.hook_1.0.0.v20080610
Master=0

When I uncomment the above line I get the following error.

org.osgi.framework.BundleException: The activator
de.tecis.excalibur.e2.E2Plugin for bundle de.tecis.excalibur.e2 is invalid

Somehow suddly he doesn't seem to find the activator of my application
bundle anymore.

I guess there is a problem with the classloader but I cannot find where
the problem is. Maybe someone could point me into the right direction and
give me a hint of what I might be doing wrong.

Thanks in advance for any help.

This can indicate a RuntimeException being thrown in your Activator.start()
method. I would step through this method with a debugger.

It is indeed a RuntimeException. I get the following error whenever I try
to call methods of any of my other plugins. It seems that somehow my
application plugin cannot find my other plugins anymore when I add the
equinox transforms hook. Does anyone have any idea of why this occurs?

Christian,

I'm not sure what to say; that's a very strange error as the NPE shouldn't
ever happen so long as the bundle isn't somehow corrupt or unavailable. Is
your transform bundle using classes from bundles that get installed later on
by update configurator??

Beyond that, all I can think of is that it might be worthwhile to again
debug and validate that your transform is really working as expected. You
might also try running on 3.4 to see if you get the same result.

Hi!

Maybe this is related to:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=252098

(which is fixed in head a minute ago).

Cheers,
