[mule-user] Unable to use idempotent-secure-hash-filter

[Bob Craig]

I am trying to use the idempotent-secure-hash-filter to filter out processing jobs that I have already processed. The documentation available for idempotent-secure-hash-filter seems minimal but straightforward.

When I follow the example shown in the documentation at [http://www.mulesoft.org/documentation/display/MULE3USER/Routing+Message+Processors#RoutingMessageProcessors-IdempotentSecureHashMessageFilter] , however, I get a SAXParseException when I try to run my flow (shown below).

This is how I am trying to invoke the filter...
<idempotent-secure-hash-filter>
<simple-text-file-store name="inews-story-store" directory="/users/bob_craig/temp" maxEntries="255"/>
</idempotent-secure-hash-filter>

Any ideas what I have wrong?

Are you running standalone? It seems you are not. The stacktrace lists old xerces embedded in jdk, and they are way too old. Mule standalone endorses more recent working versions, do the same for your jdk.

I'm not sure I completely follow. I am running in the Mule IDE but using a deployment of Mule 3.2.0 and JDK 6. Here is the output when I start up a flow in Mule from the IDE.

What would I do differently?

Bob,

When you run Mule standalone, i.e. install Mule distro and run from command line bin/mule, there's a bit of magic happening. Mule adjusts jdk endorsed libs to use recent xml libs. You can find these in the Mule's lib/endorsed dir. When you run in Eclipse this doesn't happen and it's your responsibility then. One of the easiest solutions is identify which jdk is used to launch java programs from eclipse and copy the libs into $JAVA_HOME/jre/lib/endorsed.

HTH,
Andrew

Interestingly, I can use the base version - <idempotent-message-filter> without any other changes.

This generates an error...

<idempotent-secure-hash-filter>
<simple-text-file-store name="inews-story-store" directory="/users/bob_craig/temp" maxEntries="255"/>
</idempotent-secure-hash-filter>

But this works fine...
<idempotent-message-filter idExpression="#[header:invocation:queue-locator]">
<simple-text-file-store name="inews-story-store" directory="/users/bob_craig/temp" maxEntries="1000"/>
</idempotent-message-filter>

Config elements inherit from each other. Upgrade the libs, bundled jdk ones are way too broken.
