-------------------------------------------------------------------------------------------------------
Key: SYNAPSE-419
URL: https://issues.apache.org/jira/browse/SYNAPSE-419
Project: Synapse
Issue Type: Bug
Affects Versions: 1.2
Environment: Ubuntu7.10, JDK1.5.0_14
Reporter: Evanthika Amarasiri
Assignee: Ruwan Linton
Tried out the below configuration where a document is being sent to be uploaded
through SwA. When the request is sent from the client it fails since the
service required to do this task is not available and then a
NullPointerException is thrown on the Synapse console.
The configuration tried out is as below
******************************************************************************************************
<definitions xmlns="http://ws.apache.org/ns/synapse";>
<in>
<filter source="get-property('Action')"
regex="urn:uploadFileUsingSwA">
<property name="example" value="swa"/>
<send>
<endpoint>
<address
uri="http://localhost:9000/soap/MTOMSwASampleService"; optimize="swa"/>
</endpoint>
</send>
</filter>
</in>
<out>
<filter source="get-property('example')" regex="swa">
<property name="enableSwA" value="true" scope="axis2"/>
</filter>
<send/>
</out>
</definitions>
When executing the client, the following exception was thrown
