Problem using IBM-RAD / AXIS2

[Suman Mazumder]

Hi,

I am a newbie in WebServices.

I've got a problem in using a combination of 'IBM-RAD (6.0.0)' (for Service / running on websphere 6) and 'AXIS2(1.4)' (for Client / running in tomcat 5.5).

Simple Types / String / Bean objects are doing fine.
But, for 'array of Bean objects', I'm facing a problem. It's not working properly.

Giving you the details:

1. Bean Class for Service (IBM-RAD):

public class VectorVO
{

private String FName;


public String getFName()
{

return FName;

}



public void setFName(String name)
{

FName = name;

}

}



2. Service Class (IBM-RAD):

public class VectorTest
{

public VectorVO[] doCall(String p_str)

{

VectorVO l_objVO1 = new VectorVO();

VectorVO l_objVO2 = new VectorVO();

VectorVO l_objVO3 = new VectorVO();



VectorVO[] l_objVectorVO = new VectorVO[3];



l_objVectorVO[0] = l_objVO1;

l_objVectorVO[1] = l_objVO2;

l_objVectorVO[2] = l_objVO2;



return l_objVectorVO;

}

}

3. WSDL (made automatically by IBM-RAD):

4. Client Class (AXIS2 / NetBeans 5.5):

import javax.xml.namespace.QName;

import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;

public class ClientMainWS
{
public static void main(String[] args1) throws AxisFault {

RPCServiceClient serviceClient = new RPCServiceClient();

Options options = serviceClient.getOptions();

EndpointReference targetEPR = new EndpointReference("http://192.168.1.192:9080/TestWebService4/services/VectorTest");

options.setTo(targetEPR);

options.setAction("doCall");

QName opSetWeather = new QName("http://service.pojo.sample", "doCall");

Object[] opGetWeatherArgs = new Object[] {"Suman"};
Class[] returnTypes = new Class[] { VectorVO[].class};


Object[] response = serviceClient.invokeBlocking(opSetWeather, opGetWeatherArgs, returnTypes);

System.out.println("Response Length: "+response.length);



VectorVO[] result = (VectorVO[]) response[0];

System.out.println("Result Length: "+result.length);


VectorVO vo1 = result[0];
//VectorVO vo2 = result[1];
//VectorVO vo3 = result[2];

System.out.println("Got Result1: "+result);


System.out.println("Got vo1: "+vo1);
//System.out.println("Got vo2: "+vo2);
//System.out.println("Got vo3: "+vo3);
}
}

[In the Client side I have the same Bean Class to get the values]

5. Output I'm Getting (Netbeans 5.5):

init:
deps-jar:
compile:
run:
log4j:WARN No appenders could be found for logger (org.apache.axis2.util.Loader).
log4j:WARN Please initialize the log4j system properly.
Response Length: 1
Result Length: 1
Got Result1: [LVectorVO;@406199
Got vo1: VectorVO@2a4983
BUILD SUCCESSFUL (total time: 4 seconds)

[I think Result Length should be 3]

6. If I omit the commented lines, I'm getting the exception:

init:
deps-jar:
compile:
run:
log4j:WARN No appenders could be found for logger (org.apache.axis2.util.Loader).
log4j:WARN Please initialize the log4j system properly.
Response Length: 1
Result Length1: 1
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
at ClientMainWS.main(ClientMainWS.java:423)
Java Result: 1
BUILD SUCCESSFUL (total time: 2 seconds)


N.B.: The test Client made by IBM-RAD is running without any problem. I've got the AXIS2 Client code from different forums, and they say that It works fine. But, I'm at a loss. I've been searching for a week and trying to get a solution, but in vain.

What's the problem?
What's the solution?

Please help me.

Thanks in advance...
