OSGi : fails to load CXF classes

Hi all,

I must use CXF (client) within a RCP (eclipse) application. Here's my config:
- I have defined a plugin project that contains a library with the code that makes the CXF call (actually uses WebClient). This bundle A imports org.apache.cxf.bundle-minimal (Require-bundle) and specifies the library in the Classpath header of the MANIFEST.
- My OSGi runtime contains servicemix's jsr311 bundle, and this bundle is the only provider of javax.ws.rs.*
- I'm using Gemini blueprint to expose the service defined in the library of bundle A
- Bundle B (ui bundle) imports service defined in bundle A, also using Gemini blueprint facilities.
- When invoking the service from B, it tries to create a WebClient to issue a http request, and I get the following error:

Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: com.sun.ws.rs.ext.RuntimeDelegateImpl

       ... 54 more

Based on what I know from FactoryFinder, it tries to load a file named META-INF/services/javax.ws.rs.ext.RuntimeDelegate, that contains the implementation class name of the RuntimeDelegate to use. If either the file or the class defined in the file cannot be loaded, it tries to load the default RuntimeDelegate implementation, which is com.sun.ws.rs.ext.RuntimeDelegateImpl. Thus getting this exception.

org.apache.cxf.bundle-minimal contains a file named META-INF/services/javax.ws.rs.ext.RuntimeDelegate, and this file contains a class name that exists in cxf bundle, thus I rather suspect some classloading issues related to bundles since CXF and servicemix jsr311 are in separate bundles.

Did anybody already face such an issue ?
Thanks in advance,

We too faced similar problem in OSGi. Setting system property javax.ws.rs.ext.RuntimeDelegate=org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl, issue is resolved.

Yep.   It's a shame the 'standard' api jars from Oracle don't have this capability built into it.    ServiceMix has "OSGi enabled" versions of a bunch of the spec jars including jaxws, jaxb, jaxrs, etc…   Definitely use them if you can.

Both solutions work, thank you guys : I have initially added the system property, but finally prefer the solution to set Autostart to true on servicemix's jsr311 bundle.
This is actually how it's supposed to work : this bundle has an activator that register loaders for loading classes from other bundles when using FactoryFinder, see classes in or.apache.servicemix.specs.locator.

Hi Gaëtan,

I had the same problem than you, I have explained how to fix that at
http://angelozerr.wordpress.com/2012/05/29/eclipse_spring_dosgi_step1/#serverMock

that's to say:

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
It’s very important too to unselect *javax.ws.rs.jsr311-api* (JAX-RS API)
and select *org.apache.servicemix.specs.jsr311-api* with *Auto-Start to true
*.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Hope it's the same problem than you.

RE: OSGi : fails to load CXF classes

Posted by "Malisetti, Ramanjaneyulu" <Ra...@ca.com>.
We too faced similar problem in OSGi. Setting system property javax.ws.rs.ext.RuntimeDelegate=org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl, issue is resolved.

Subject: OSGi : fails to load CXF classes

Hi all,

I must use CXF (client) within a RCP (eclipse) application. Here's my config:
- I have defined a plugin project that contains a library with the code that makes the CXF call (actually uses WebClient). This bundle A imports org.apache.cxf.bundle-minimal (Require-bundle) and specifies the library in the Classpath header of the MANIFEST.
- My OSGi runtime contains servicemix's jsr311 bundle, and this bundle is the only provider of javax.ws.rs.*
- I'm using Gemini blueprint to expose the service defined in the library of bundle A
- Bundle B (ui bundle) imports service defined in bundle A, also using Gemini blueprint facilities.
- When invoking the service from B, it tries to create a WebClient to issue a http request, and I get the following error:

Based on what I know from FactoryFinder, it tries to load a file named META-INF/services/javax.ws.rs.ext.RuntimeDelegate, that contains the implementation class name of the RuntimeDelegate to use. If either the file or the class defined in the file cannot be loaded, it tries to load the default RuntimeDelegate implementation, which is com.sun.ws.rs.ext.RuntimeDelegateImpl. Thus getting this exception.

org.apache.cxf.bundle-minimal contains a file named META-INF/services/javax.ws.rs.ext.RuntimeDelegate, and this file contains a class name that exists in cxf bundle, thus I rather suspect some classloading issues related to bundles since CXF and servicemix jsr311 are in separate bundles.

Did anybody already face such an issue ?
Thanks in advance,
