Is there a way to throw an exception in xpl

Hi, I want to throw an exception in some situation in xpl file. Something like this:

<p:choose href="#instance">
<p:when test="/test='true'">

<p:processor name="oxf:identity">
<p:input name="data" href="instance"/>
<p:output name="data" id="result"/>
</p:processor>

</p:when>
<p:otherwise>
// throw an java exception with some messages.

</p:otherwise>
</p:choose>

It seems if an error occurs, the java exception will be stored in request and oxf:exception will turn it into an xml.

Is there a processor to create a java exception object and put it request?

Thanks,
James

Hi you can siply send one node with xslt processor and displya the same as follows

<p:choose href="#instance">
<p:when test="/test='true'">
................
<p:processor name="oxf:identity">
<p:input name="data" href="instance"/>
<p:output name="data" ref="data"/>
</p:processor>

</p:when>
<p:otherwise>

<p:processor name="oxf:xslt-2.0">
<p:input name="data" href="#refreshsession"/>
<p:input name="config">
<query xsl:version="2.0">
<message>This is exception message</message>
</query>
</p:input>
<p:output name="data" ref="data"/>
</p:processor>

</p:otherwise>
</p:choose>

We have an oxf:error processor which just takes a config input. The
string passed in that config input is passed as parameter to a
ValidationException. You might want to try this.

Thank you for your information!

I want it jump out the xpl and go to error page, not continue. I have solved the problem with Erik's help.

Thanks,
James
