I guess it's caused by missing some jars either in apache lib or in my axisservice lib actually i put all the jersey jars into the axisservice lib,,, I have test the axis2 --> restful with the webservice test explorer in eclipse, it works just fine but whenever i try it from a client (as i showed in the scenario above) it doesnt work.

Please advice, thanks in advance

回答1:

The com.sun.ws.rs.ext package, and therefore RuntimeDelegateImpl, is contained in the jersey client jar. If you're using maven then add this dependency to your pom.xml (here I'm using jersey client v1.12):

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-client</artifactId>
    <version>1.12</version>
</dependency>

回答2:

Please add the following dependencies in your maven project which provides the implementation of the RuntimeDelegate

<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-bundle-jaxrs</artifactId>
        <version>2.7.18</version>
</dependency>
