I am new to eclipse OSGi. Currently, I am using eclipse OSGi 3.5.1 version. I have 4 bundles. When I invoke all these bundles from eclipse all the bundles start without any issue. But the same bundles, when I try to invoke from command line (java -jar jar_location -console -configuration configuration), getting java.lang.ClassNotFoundException: javax.xml.xpath.XPathExpressionException. This class is present in rt.jar which is in java_home classpath.

Same bundles run without any problem with same command when I run them with 3.2.2 version OSGi jar. When I change osgi 3.5.1 with version 3.2.2, all bundles run fine.

I think, running bundles from command line, it is not able to pick classes which are in rt.jar's javax package.

So is it a bug in new version which was not exist in older version or some configuration issue? Please suggest me, should I use new version(3.5.1) or move back to old version(3.2.2)?

Any workaround to solve this problem in 3.5.1 version.

Have you declared a dependency on javax.xml.xpath in your manifest with
Import-Package?

See this wiki page: http://wiki.eclipse.org/Equinox_Boot_Delegation
