Hi all,
I have a strange problem concerning loading a class from the batik plugin.
Short description: I'm playing with the GMF Taipan example and the batik
plugin. I added the batik plugin to the Taipan dependencies and at compile
time everything works fine.
If I start a new workbench, create a diagram and add an element which needs
a class which belongs to the org.apache.batik.bridge package, I get an error
loading the class I need:
Caused by: java.lang.NoClassDefFoundError:
org/apache/batik/bridge/UserAgentAdapter
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:620)
I really don't know why it's working, maybe u can give me a hint.
Cheers,
Andreas

Did you add the dependency by editing the MANIFEST.MF using the
Dependencies tab? It's a common mistake to edit the project's
properties directly...

ok, my fault - I of course added the dependencie via the manifest file. But
I made that mistake
as I started to develop plugins ;). Any other hints?

Andreas,
Are the required plugins included in the set of plugins specified in the
launcher's Plug-in tab? Running with the -debug flag will produce
diagnostic information in the Error log that might be helpful;
-consolelog is useful for spitting that out to the console as they are
produced.

Hi Ed,
yes, the required plugins are already containted in the target platform. =
It seems like the platform even doesn't try to load the classes I need. =
I attached
the error log - maybe that helps...

I reduced the problem to a simple action:
public void run(IAction action) {
URL svgURL =3D FileLocator.find(Platform.getBundle("com.example.svg"), =
new Path(
"images/box.svg"), null);
SVGUserAgent agent =3D new SVGUserAgent(12,null);
// UserAgent agent =3D new UserAgentAdapter();
The problem is the SVGUserAgentAdapter which extends from the =
UserAgentAdapter. When the platform try to load SVGUserAgentAdapter, I =
get an error that the class UserAgentAdapter cannot be resolved. BUT: If =
I just use the UserAgentAdapter (by commenting out the =
SVGUserAgentAdapter and commenting in the last line) the =
UserAgentAdapter can be loaded! So - strange problem here...

Andreas,
Did you try the -clean -debug flags I suggested? It doesn't look like
it... You might want to install in a fresh new location and try with
that installation instead...

Andreas,
I suppose it could be a bug. Or maybe the problem is with how the
plugin is packaged... Maybe you could describe the simplified scenario
in a bugzilla...

I had a class loader problem myself, this was my scenario:
plugin_util was exporting xstream to other plugins
plugin_a depends on plugin_util.
I could serialize from plugin_a using xstream. However, deserialization
from plugin_a did not work: xstream could not find a class from plugin_a.
The problem was that xstream used the class loader of plugin_a which had
no clue about classes in plugin_a. My solution was to add xstream directly
to plugin_a. There might be a better way, using buddy plugins but I didn't
try that.
Maybe this helps.
