Handling Java Exception via WSIF

Question

Hi all,
On BPEL, I want to catch exception thrown by Java method exposed via WSIF so that I can propagate the error message to BPEL client, but it seems that instead of getting my exception, BPEL keeps getting remoteException, is it possible at all ?
Below is my Java class:
public class InvalidParameterException extends Exception
  public InvalidParameterException(String string)
    super(string);
public final class CommonUtil
   public static String formatMSISDN(String rawMSISDN) throws InvalidParameterException
      throw new InvalidParameterException("test");
      return "test2";
}And below is part the WSDL:
  <message name="RawMSISDNMessage">
    <part name="rawMSISDN" type="xsd:string"/>
  </message>
  <message name="FormattedMSISDNMessage">
    <part name="formattedMSISDN" type="xsd:string"/>
  </message>
  <message name="InvalidParameterException">
    <part name="message" type="xsd:string"/>
  </message>
  <portType name="CommonUtilityPT">
    <operation name="formatMSISDN">
      <input name="FormatMSISDNRequest" message="tns:RawMSISDNMessage"/>
      <output name="FormatMSISDNResponse" message="tns:FormattedMSISDNMessage"/>
      <fault name="FormatMSISDNFault" message="tns:InvalidParameterException"/>
    </operation>
  </portType>
  <binding name="JavaBinding" type="tns:CommonUtilityPT">
    <java:binding/>
    <format:typeMapping encoding="Java" style="Java">
      <format:typeMap typeName="xsd:string" formatType="java.lang.String"/>
    </format:typeMapping>
    <operation name="formatMSISDN">
      <java:operation methodName="formatMSISDN" methodType="static"
                      parameterOrder="rawMSISDN" returnPart="formattedMSISDN"/>
      <input name="FormatMSISDNRequest"/>
      <output name="FormatMSISDNResponse"/>
      <fault name="FormatMSISDNFault"/>
    </operation>
  </binding>
  <service name="CommonUtility">
    <port name="JavaPort" binding="tns:JavaBinding">
      <java:address className="com.visitek.xlpoc.CommonUtil"/>
    </port>
  </service>
...Any help would be greatly appreciated.
Best Regards,
James

Hi,
After restarting SOA Suite, it seems that the expected fault is returned (InvalidParameterException). But this time another exception is thrown which indicates as if fault handler for InvalidParameterException was not specified, while I've done so in BPEL:
  <faultHandlers>
    <catch faultName="ns3:InvalidParameterException">
      <sequence name="Sequence">
        <assign name="AssignOutput">
          <copy>
            <from expression="ora:getFaultName()"/>
            <to variable="outputVariable" part="payload"
                query="/client:processResponse/client:message"/>
          </copy>
        </assign>
        <reply name="ReplyOutput" variable="outputVariable"
               partnerLink="allowexistofferbpel_client"
               portType="client:AllowExistOfferBPEL" operation="process"/>
        <terminate name="ExitBPEL"/>
      </sequence>
    </catch>
  </faultHandlers>
...And below is the exception stacktrace:

...The attribute xmlns in InvalidParameterException is empty, this could be the problem, but I don't why.
Any help would be greatly appreciated.
