I want to implement payload inside </p> <p>I AM NOT ABLE TO GET THE PROPERTY VALUE OF sessionIDFromClassMediator SO MY FILTER NEVER GETS TRUE AND CAN'T GET INSIDE THE FILTER</p> <pre><code> **&lt;filter xpath="get-property('sessionIDFromClassMediator') = get-property('SessionID')"&gt; &lt;then&gt; &lt;log level="custom"&gt; &lt;property name="STATE" value="message is sent to queue"/&gt; &lt;/log&gt; &lt;property name="OUT_ONLY" value="true"/&gt; &lt;property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/&gt; &lt;header name="To" action="remove"/&gt; &lt;property name="RESPONSE" value="true" scope="default" type="STRING"/&gt; &lt;property name="NO_ENTITY_BODY" scope="axis2" action="remove"/&gt; &lt;payloadFactory&gt; &lt;format&gt; &lt;ns1:PostPublicationResponse xmlns:ns1="http://www.openoandm.org/xml/ISBM/"&gt; &lt;ns1:MessageID&gt;$1&lt;/ns1:MessageID&gt; &lt;/ns1:PostPublicationResponse&gt; &lt;/format&gt; &lt;args&gt; &lt;arg expression="get-property('getMessageIDFromClassMed')"/&gt; &lt;/args&gt; &lt;/payloadFactory&gt; &lt;send/&gt; &lt;/then&gt; &lt;else&gt; &lt;log level="full"&gt; &lt;property name="FilterNotRunning" value="----------FilterNotRunning------------------"/&gt; &lt;/log&gt; &lt;drop/&gt; &lt;/else&gt; &lt;/filter&gt;** </code></pre> <p>part.THE MAIN PROBLEM IS THAT THE FIRST FILTER IS EXECUTED WHEN I ENVOKE OPERATION OPENPUBLICATION, AND WHEN I ENVOKE THE SECOND OPERATION ALL THE PROPERTY VALUE GET RESET. SO HOW CAN I MAKE PROPERTY VALUE PERSISTENT SO THAT IT IS NEVER LOST? Hope you understand my question and looking forward to your solutions. Thanks in advance</p>
