ClassCastException with OSGI bundle -

-

i working on osgi bundle, uses javax.ws.rs-api (2.0.1). karaf having jsr311-api (1.1.1) loaded bundle. when try load osgi bundle, see following exception. there way can ignore loaded bundle?

the activate method has thrown exception java.lang.linkageerror: classcastexception: attempting castbundle://137.0:1/javax/ws/rs/ext/runtimedelegate.class bundle://177.0:1/javax/ws/rs/ext/runtimedelegate.class     @ javax.ws.rs.ext.runtimedelegate.finddelegate(runtimedelegate.java:146)[137:javax.ws.rs.jsr311-api:1.1.1]     @ javax.ws.rs.ext.runtimedelegate.getinstance(runtimedelegate.java:120)[137:javax.ws.rs.jsr311-api:1.1.1]     @ javax.ws.rs.core.uribuilder.newinstance(uribuilder.java:95)[137:javax.ws.rs.jsr311-api:1.1.1]     @ javax.ws.rs.core.uribuilder.fromuri(uribuilder.java:119)[137:javax.ws.rs.jsr311-api:1.1.1]

your bundle must import packages need versions. have create meta-inf\manifest.mf import-package header, contain list of packages required versions.

import-package: javax.ws.rs.ext,version="2.0.1"

list packages cause conflict. think here are:

javax.ws.rs,version="2.0.1" javax.ws.rs.client,version="2.0.1" javax.ws.rs.container,version="2.0.1" javax.ws.rs.core,version="2.0.1" javax.ws.rs.ext,version="2.0.1"

you can specify range of versions : [2.0.1, 3) , on.

real example:

import-package: org.osgi.service.blueprint; version="[1.0.0, 2.0.0)"

you can use maven-bundle-plugin create requered manifest.mf:

        <plugin>             <groupid>org.apache.felix</groupid>             <artifactid>maven-bundle-plugin</artifactid>             <version>2.3.7</version>             <extensions>true</extensions>             <configuration>                 <instructions>                     <bundle-symbolicname>${project.artifactid}</bundle-symbolicname>                     <bundle-description>${project.description}</bundle-description>                     <import-package>                         javax.ws.rs;version=2.0.1,                         javax.ws.rs.client;version=2.0.1,                         javax.ws.rs.container;version=2.0.1,                         javax.ws.rs.core;version=2.0.1,                         javax.ws.rs.ext;version=2.0.1,                         *,                         org.apache.camel.osgi                     </import-package>                     <export-package>                         your.package                     </export-package>                 </instructions>             </configuration>         </plugin>

don't forget install bundle version 2.0.1
