Hi I am writing a java program using xml interface to generate a workitem in mQWF 3.5. It works ok.
The xml msg is below:

<?xml version="1.0" ="UTF-8"?>
<WfMessage>
<WfMessageHeader>
<ResponseRequired>IfError</ResponseRequired>
<UserContext>This is my return data</UserContext>
</WfMessageHeader>
<ProcessTemplateCreateAndStartInstance>
<ProcTemplName>Approval</ProcTemplName>
<ProcInstName>MyApproval</ProcInstName>
<KeepName>false</KeepName>
<ProcInstInputData>
<approval_datainput>
<user_id>testid</user_id>
<lang_cd>en</lang_cd>
</approval_datainput>
</ProcInstInputData>
</ProcessTemplateCreateAndStartInstance>
</WfMessage>

I would like to ask 2 questions:
1) assuming the first time the xml msg is put successfully, that is, there is a generated workitem with
user_id=testid and lang_cd=en in the workflow runtime dabase
the second time and all subsequent times, if the same user_id=testid and same lang_cd=en is put again, I do not
want to create another workitem in the wf runtime dbase with same user_id and lang_cd
Does wf xml interface support this checking ? that is if workitem already existed, do not create same one...
if wf xml interface does not support this, what java api should i use to check if a workitem already existed ?

2) Is there a tag in the xm interface to copy the entire content of (input) xml msg to reply queue when there is an error.
The <ResponseRequired>IfError</ResponseRequired> tag only puts the xml msg with the error code but not the content of the xml msg to the reply queue

Thanks alot
Beth
