Creating a java client for secured esb proxy - security

Question

I want to create a java client for version proxy service present in wso2 esb. I have secured the version proxy with Username Token Authentication scenario. Now i have started creating the java client to invoke this secured proxy service and my client code is:
package org.wso2.carbon.security.ws;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.context.ConfigurationContext;
import org.apache.axis2.context.ConfigurationContextFactory;
import org.apache.axis2.description.AxisBinding;
import org.apache.axis2.description.AxisEndpoint;
import org.apache.axis2.rpc.client.RPCServiceClient;
import org.apache.neethi.Policy;
import javax.xml.namespace.QName;
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.net.URL;
import java.util.Map;
public class HelloServiceClient {
static {
System.setProperty("javax.net.ssl.trustStore", "/path/to/keystore" + File.separator+ "wso2carbon.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "wso2carbon");
}
public static void main(String[] args) {
try {
int securityScenario = getSecurityScenario();
String repository = "/path/to/repo" + File.separator + "repository";
ConfigurationContext confContext =
ConfigurationContextFactory.
createConfigurationContextFromFileSystem(repository, null);
String endPoint = "HelloServiceHttpSoap12Endpoint";
if(securityScenario == 1){
endPoint = "HelloServiceHttpsSoap12Endpoint"; // scenario 1 uses HelloServiceHttpsSoap12Endpoint
}
RPCServiceClient dynamicClient =
new RPCServiceClient(confContext,
new URL("http://pc213712:8281/services/Version?wsdl"),
new QName("http://version.services.core.carbon.wso2.org", "Version"),
endPoint);
//Engage Modules
dynamicClient.engageModule("rampart");
dynamicClient.engageModule("addressing");
//TODO : Change the port to monitor the messages through TCPMon
if(securityScenario != 1){
dynamicClient.getOptions().setTo(new EndpointReference("http://pc213712:8281/services/Version/"));
}
//Get the policy from the binding and append the rampartconfig assertion
Map endPoints = dynamicClient.getAxisService().getEndpoints();
AxisBinding axisBinding = ((AxisEndpoint) endPoints.values().iterator().next()).getBinding();
Policy policy = axisBinding.getEffectivePolicy();
**policy.addAssertion(RampartConfigBuilder.createRampartConfig(securityScenario));**
axisBinding.applyPolicy(policy);
//Invoke the service
Object[] returnArray = dynamicClient.invokeBlocking(new QName("http://www.wso2.org/types","greet"),
new Object[]{"Alice"},
new Class[]{String.class});
System.out.println((String) returnArray[0]);
} catch (Exception ex) {
ex.printStackTrace();
}
}
private static int getSecurityScenario() {
int scenarioNumber = 0;
while (scenarioNumber < 1 || scenarioNumber > 15) {
System.out.print("Insert the security scenario no : ");
String inputString = readOption();
try {
scenarioNumber = new Integer(inputString);
} catch (Exception e) {
System.out.println("invalid input, insert a integer between 1 and 15");
}
if(scenarioNumber < 1 || scenarioNumber > 15){
System.out.println("Scenario number should be between 1 and 15");
}
}
return scenarioNumber;
}
private static String readOption() {
try {
BufferedReader console = new BufferedReader(new InputStreamReader(System.in));
String str;
while ((str = console.readLine()).equals("")) {
}
return str;
} catch (Exception e) {
return null;
}
}
}
But in the above code i am struck at one line that is :
policy.addAssertion(RampartConfigBuilder.createRampartConfig(securityScenario));
Here in my rampart_core jar I am getting RampartConfigBuilder class but inside this class there is no such method called createRampartConfig. So i am unable to create Rampart configurations. What can i do to solve this issue? looking forward to your solutions. Thanks in advance
