Can weblogic client takes empty arrays being returned.

[jadeite100]

Hi All:

I am using weblogic 9.2 to generate the web service client code.
Here is my build.xml file to build the java client code:

<project name="webservices-TEST" default="client">
<taskdef name="clientgen" classname="weblogic.wsee.tools.anttasks.ClientGenTask" />
<target name="client" >
<clientgen
wsdl="

http://test:7035/TEST-engine/services/accumulator.wsdl"

destDir="clientclasses"
packageName="com.TEST.TEST2.caps.wsclient"
>

</clientgen>
</target>

</project>

Here is my client code to test the web service.

public class testWebServicesClient
{
public static void main(String[] test)
{
try {

Long recipientId = 11597997730620L;

AccumulatorWS impl = new AccumulatorWS_Impl("

http://test:7035/TEST-engine/services/accumulator.wsdl");

IAccumulatorWS iAccWS1 = impl.getIAccumulatorWS();

AccumulatorResponse response = iAccWS1.getCurrentAccumulators(recipientId, "", "", "", "en", "");

System.err.println("The status is: " + response.getStatus());

}

catch (Exception e) {

e.printStackTrace();

}






}
}

I get the following error:
java.rmi.RemoteException: Illegal Capacity: -1; nested exception is:

If I changed from

Long recipientId = 11597997730620L;

to

Long recipientId = 14998712L;

I get the error message The status is: 4.

The group that generates the web service state that the weblogic client code is choking
on empty arrays being returned. They say they have to return empty arrays
instead of nulls where no data is returned.

Is there something wrong with the weblogic tools
or am I using it incorrectly?

Frustrated.
