Fault and Error handling questions

Question

Hi,
I have a few of questions regarding exception handling :
1. Where can I find documentation (i.e. details and when thrown) on all the Standard faults available with BPEL ie. those in
http://schemas.xmlsoap.org/ws/2003/03/business-process/" and
http://schemas.oracle.com/extension
2. Let's say I do not know in advance what specific fault to catch. I add a catchAll inside my scope. When catchAll triggers, I want to get the detail faultmessages of whatever fault caused the catchAll.
3. I want to use a message type from the RuntimeFault.wsdl in my project. Should I copy over the wsdl file to my project folder ? If I do not copy over and import it from it's location (integration/orabpel/system/xmllib), the console is failing runtime when I try to render the input page.
How can I do that ?
Thanks

You can find the standard faults from the BPELspec
1.1.
In 10.1.2.0.2 (the latest released version), youcan
use some system xpath functions to extract thefault
information in <catchAll> block:
getFaultAsString( ) returns String
Or
getFaultName( ) returns QName as fault name.Hi Muruga,
Thanks for your reply.
Can you please also let me know :
1. what's the signature of these methods ?
2. I have 10.1.2.0.2 local version. However under
catchall -> assign -> xpath expression builder, I do
not see these 2 functions.
Can you please help.
ThanksHi Muruga,
I tried doing the following :
<faultHandlers>
<catch faultName="bpelx:bindingFault" faultVariable="bindingFaultVar">
<assign name="assignBindingFault">
<copy>
<from expression="concat(bpws:getVariableData('bindingFaultVar','code'),bpws:getVariableData('bindingFaultVar','summary'),bpws:getVariableData('bindingFaultVar','detail'))"/>
<to variable="outputVariable" part="payload" query="/ns1:TransmissionAck/ns1:StackTrace"/>
</copy>
</assign>
</catch>
<catchAll>
<assign name="assignCatchAll">
<copy>
<from expression=""Unexpected Error in the BPEL Process""/>
<to variable="outputVariable" part="payload" query="/ns1:TransmissionAck/ns1:TransmissionText"/>
</copy>
<copy>
<from expression="bpws:getFaultAsString()"/>
<to variable="outputVariable" part="payload" query="/ns1:TransmissionAck/ns1:StackTrace"/>
</copy>
</assign>
</catchAll>
</faultHandlers>
I got the following runtime error when an actual catchAll was caught :
