dosgi：找不到资源类的资源方法-忽略javax.ws.rs注释？

Question

i run in an exception showed below. I tried to publish a webservie using annotation with dosgi. But is looks like the annotations will be ignored.

When i use restProps.put("service.exported.configs", "org.apache.cxf. ws ");

in my Activator.java Class without javax.ws.rs annotations, it works fine and i can request the wsdl (localhost:9090/provalet?wsdl).

Here are some related threads, but non of these answers helped me:

"No resource methods" when using JAX-RS on TomEE+ -> in considered the "public" scope

CXF DOSGi is ignoring annotations http://cxf.547215.n5.nabble.com/CXF-DOSGi-is-ignoring-JAX-RS-annotations-td4495048.html -> i have no bundle named "org.apache.servicemix.specs.jsr311-api-1.1"

i also developed this example http://maksim.sorokin.dk/it/2011/09/18/maven-apache-felix-cxf-dosgi-an-example-of-dosgi-service/ -> but same exception

I work with

Assumption: I even think that is a problem with dependencies and it looks like the javax.ws.rs annotation will be ignored. Maybe i have a mistake with the bundle versions either.

Does someone know something more about this problem and how i can solve this? Please let me know, if you need more information.

kind regards lars

okay..

a working targetplatform looks like this.. it was indeed a problem with dependencies.
