Re: Handling Exception When Invoking Java Via WSIF

Hi Setya,

The 'fault' in the java binding operation has to be mapped to a 'message' in
the WSDL.

The 'message' can contain a part with name 'fault' which is mapped to a user
defined Exception type.

Once you have this, WSIF will convert the Exception to a Fault and the
exception object can be retrieved from the Fault parts.

Hope it helps.

Thanks
Prakash

Hi all,<br>
<br>
From BPEL, I need to catch exceptions thrown by invocation to Java method<b=
r>
via WSIF, but it always returns remoteFault instead. Is it possible at all =
?<br>
<br>
Here&#39;s part my WSDL file:<br>
<br>
...<br>
 =A0&lt;message name=3D&quot;RawMSISDNMessage&quot;&gt;<br>

<br>

<br>
public final class CommonUtil<br>

 =A0public static String formatMSISDN(String rawMSISDN) throws<br>
InvalidParameterException<br>
 =A0{<br>
 =A0 =A0throw new InvalidParameterException(&quot;test&quot;);<br>
<br>
 =A0 =A0return &quot;test2&quot;;<br>
 =A0}<br>
}<br>
<br>
Any help would be greatly appreciated.<br>
