[jira] Updated: (SYNAPSE-503) get-property function is not
recognized in xquery variable expression attribute
[ https://issues.apache.org/jira/browse/SYNAPSE-503?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michal Stochmialek updated SYNAPSE-503:
---------------------------------------
Description:
I'm transforming response of the remote service in outSequence of a proxy.
I'm using xquery mediator. I want to change the format of the payload of the response
and also I want to insert a payload of the request into a first element of the response.
1. proxy: gets request A,
2. inSequence: transforms request A to request B,
3. endpoint: sends request B to remote service,
4. endpoint: receives response B,
5. outSequence: transforms response B to response A with request A included.
To do that, I'm storing the request A payload in a variable and in outSequence
I'm want to use it in XQUERY mediator while transforming the response.
Here's a fragment of the synapse.xml:
<xquery key="response.xq" trace="enable">
<variable name="payload" type="ELEMENT"/>
<variable name="request" expression="synapse:get-property('body')" type="ELEMENT"/>
</xquery>
On the runtime I've got following exception:

After looking a bit at XQueryMediator code it seems it uses AXIOMXPath class instead of SynapseXPath class.
This seems to be a reason of the exception.
