I get

java.lang.NoClassDefFoundError:
org/apache/jackrabbit/core/TransientRepository

when I try to start my bundle in Equinox.

That class is in jackrabbit-core-1.0.jar that is in ./lib of my jar and I
have put it in classpath in MANIFEST.MF:

Bundle-ClassPath: .,
./lib/jackrabbit-core-1.0.jar

It works fine in knopflerfish.

Any help appreciated.

Full stack trace is:

That can happen e.g. if your class is found but it executes a static initialiser (i.e. a public static final assignment) that uses another class that's not exported by the system bundle. You could try using 'javap' to find out what it is.

I seem to recall that KF system bundle exports all packages it finds on the classpath, whereas Equinox doesn't. You can specify a configuration (more at http://wiki.eclipse.org/index.php/Equinox_Boot_Delegation). Alternatively, it needs a package that you've not imported.

Thanks for response, but I still cannot make it running!

I have added
osgi.compatibility.bootdelegation=false
and
org.osgi.framework.bootdelegation=java.*
lines to ./configuration/config.ini.

Can u plz elaborate what I need to do?

The problem was with './' before in
Bundle-ClassPath: ., ./lib/jackrabbit-core-1.0.jar

Also few problem with 'org.osgi.framework.bootdelegation' configuration.
