Question

I am running OSGi framework through CLI by running command as below:

java -jar org.eclipse.osgi_3.6.2.R36x_v20110210.jar -console

My plugins run fine but while running my plugin that requires JAXB packages of system library (JavaSE1.6.xx) to parse xml file I am getting exception trace as below:

Answer 1

I think there is a conflict with different versions of javax.xml.bind.* packages. I guess they are exported by the System library and a xerces (?) jar?

So you’ll need to find out which bundle exports those packages, and resolve the conflict.
