WSO2 ESB - Access original message from fault - wso2

Question

My goal is to put messages that return a soap error on a queue, in order to retry them later.
I have nearly all working, but the most important part : I can't access the original message from the fault sequence of my proxy :(
I first made a proxy service that returns an error for a given value, or OK for the other values :
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="TestProxyService" transports="http https" startOnLoad="true" trace="disable">
<target>
<inSequence>
<log level="custom">
<property name="TestProxyService" value="InSequence"/>
</log>
<switch xmlns:bnc="http://bnc.org/" source="//bnc:id">
<case regex="1">
<log level="custom">
<property name="TestProxyService" value="Send Error !"/>
</log>
<makefault version="soap11">
<code xmlns:soap11Env="http://schemas.xmlsoap.org/soap/envelope/" value="soap11Env:VersionMismatch"/>
<reason value="ERROR ERROR ERROR"/>
<detail>ERROR</detail>
</makefault>
<respond/>
</case>
<default>
<log level="custom">
<property name="TestProxyService" value="No Error"/>
</log>
<log level="custom">
<property name="id" expression="//bnc:id"/>
</log>
<payloadFactory media-type="xml">
<format>
<bnc:response>OK</bnc:response>
</format>
<args/>
</payloadFactory>
<respond/>
</default>
</switch>
</inSequence>
<outSequence/>
<faultSequence/>
</target>
</proxy>
And it works fine
I then made another proxy, that uses the first one as an endpoint to test the queuing on error :
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="QueuingProxyService" transports="https http" startOnLoad="true" trace="disable">
<target>
<inSequence>
<property name="FORCE_ERROR_ON_SOAP_FAULT" value="true" scope="default" type="STRING"/>
<send>
<endpoint key="TestProxyServiceEndpoint"/>
</send>
</inSequence>
<outSequence>
<send/>
</outSequence>
<faultSequence>
<store messageStore="No1MessageStore"/>
<makefault version="soap11">
<code xmlns:soap11Env="http://schemas.xmlsoap.org/soap/envelope/" value="soap11Env:VersionMismatch"/>
<reason value="There has been an error"/>
<detail>We will retry later</detail>
</makefault>
<send/>
</faultSequence>
</target>
</proxy>
The message that is stored is the one made by the makefault in the TestProxy
I tried to save the original message in a property (in the inSequence) with
<property name="OriginalBody" expression="$body" scope="axis2" type="OM"/>
but in the faultSequence, when i do this :
<log level="custom">
<property name="OriginalBody" expression="get-property('OriginalBody')"/>
</log>
I got null as a result :(
Does anyone have an idea ?
Thanks !

Answer 1

remove scope "axis2" when defining property "OriginalBody" or explicitely specify scope="default" :
<property name="OriginalBody" expression="$body" type="OM"/>
