Hi,
I'm trying to implement a plug-in for epsilon.
In the making, I needed to call a java source code (which was using two JAR files that were added to its build path), using the Native method in epsilon.
For that I followed the next guide: http://www.eclipse.org/gmt/epsilon/doc/articles/call-java-fr om-epsilon/
When I call the Native for the packages, the next error occours:
Internal error: java.lang.NoClassDefFoundError: org/springframework/beans/factory/BeanNameAware
at java.lang.ClassLoader.defineClass1[Native Method]
at java.lang.ClassLoader.defineClass[Unknown Source]
at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.def ineClass[DefaultClassLoader.java:183]
at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.defineC lass[ClasspathManager.java:576]
at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findCla ssImpl[ClasspathManager.java:546]
at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLoc alClassImpl[ClasspathManager.java:477]
at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLoc alClass_LockClassLoader[ClasspathManager.java:465]
at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLoc alClass[ClasspathManager.java:445]
at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.fin dLocalClass[DefaultClassLoader.java:211]
at org.eclipse.osgi.internal.loader.BundleLoader.findLocalClass [BundleLoader.java:381]
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInter nal[BundleLoader.java:457]
...
I tried adding the packages that are located in those two JAR files to the exported packages list in the Runtime tab, but it didn't help.
How can I call a java code that uses external JARS, using epsilon's Native method?
Thanks!

Hi,
Can you instantiate this class from the Java code of your plugin? If
not, you may want to turn your jars into plugins (as per
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. pde.doc.user/guide/tools/project_wizards/plugin_from_archive s.htm)
and then add them as dependencies to your existing plugin.
Cheers,
Dimitris
