WSO2 ESB - Rampart Password Callback class - WSPasswordCallback cannot be cast - wso2

Question

I want to to invoke a secured backend service in WSO2 ESB 5.0.0 with rampart configuration and Password Callback class
package com.yenlo.wso2.services;
import org.apache.ws.security.WSPasswordCallback;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.UnsupportedCallbackException;
import java.io.IOException;
public class PWCBHandler implements CallbackHandler {
public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException {
WSPasswordCallback pc = (WSPasswordCallback) callbacks[0];
// set the password for our message.
pc.setPassword("YENLO_TEST");
}
}
When i call the proxy service this error occurs:
org.apache.ws.security.WSPasswordCallback cannot be cast to org.apache.ws.security.WSPasswordCallback
I have compiled my source code with wss4j 1.6.17 and 1.5.12. Nothing's Changed.

Answer 1

I've created a new callbackhandler project from scratch and got it working with a few sidenodes:
- I've used the following dependency in the main pom.xml:
<dependency>
<groupId>org.apache.ws.security</groupId>
<artifactId>wss4j</artifactId>
<version>1.5.11</version>
</dependency>
I put the resulting '.jar' in repository/components/lib. Also I removed the .jar from repository/components/dropins when redeploying to be sure(ESB creates a file there during startup when processing the .jar)
I've put the entire project here. Build using 'mvn clean package'.
Good luck! I'd like to hear back if you succeeded!

Have a look at the available version of wss4j inside "wso2esb-5.0.0/repository/components/plugins" folder. It looks like you are using a different version in the compile time, that may lead to this kind of issue.
Try to use wss4j with the following dependency version when compiling.
version=1.5.11.wso2v14
groupId=org.apache.ws.security.wso2
artifactId=wss4j
