Hi,

I am having some trouble running the project published at: https://github.com/camunda/camunda-consulting/tree/master/one-time-examples/2015-01-webinars/webinar-data-connectors-scripts

First I am unable to resolve camunda-bpm-xslt which is OK as I understand is only for enterprise edition so maybe it's not public. I removed the dependency from the pom.xml and also I replaced the *retrieve bank data (SOAP)* connector payload with a freemarker version.

The trouble is that when I run testNotApprove inside eclipse (which is by the way the prepackaged Camunda Modeler installed in Eclipse Kepler) I get the following stacktrace:

Can anyone help me figure this out?

Thanks.

Hi Horia.

For XSLT you are right.

Looking at your exception you experience an issue we resolved in 7.2.1 (enterprise patch release) or 7.3.0-alpha1. So you could try with the newest alpha release. As an alternative solution you can add the @XmlRootElement to the CreditorApplication class – as this was required before resolving the issue…

Hope that helps

Cheers

Bernd

Yes, that was the problem with the JUnit environment. Thank you for the quick response.

If anyone needs it, here is the freemarker version for the payload input parameter of the soap-http-connector:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:blz="http://thomas-bayer.com/blz/">
   <soap:Header/>
   <soap:Body>
      <blz:getBank>
         <blz:blz>${application.bankIdentifierCode}</blz:blz>
      </blz:getBank>
   </soap:Body>
</soap:Envelope>

Now I am trying to deploy the process to tomcat (downloaded from http://camunda.org/release/camunda-bpm/tomcat/7.2/camunda-bpm-tomcat-7.2.0.zip).

I deployed the war file build from eclipse with pom.xml > Run As > Maven Install (not from ant)

The process deploys fine but when I try to start it from Camunda Tasklist I get a runtime exception on the tomcat logs (I also attached to this post a screenshot with the error the web UI displays):

Your fix was to change the CreditorApplication to have the @XmlRootElement annotation - right?

Right. This solved the initial problem i.e. running unit tests inside eclipse.

The runtime exception I get on tomcat is generated even if @XmlRootElement is present.

Hi Horia.

OK – I quickly tried to reproduce your error and was successful on a 7.2.0 – but not on a 7.2.2. So I think this is a bug already fixed (I could not completely nail it down – but I think it is around https://app.camunda.com/jira/browse/CAM-3167). So you have to switch to an enterprise release or use the 7.3.0-alpha1.

Cheers

Bernd

P.S: I commited a change in the example on GitHub to not rely on XSLT to make it easier to use in the first place. I already had exactly the same freemarker code as you posted locally on my machine :-)

Hi,

I can confirm that on http://camunda.org/release/camunda-bpm/tomcat/7.3/camunda-bpm-tomcat-7.3.0-alpha1.zip the process runs fine.

One must however first put webinar-file-connector-0.0.1-SNAPSHOT.jar into $tomcat_home/lib directory. If it's put into $tomcat_home/webapps/webinar-data-connectors-scripts/WEB-INF/lib the process will throw on approved branch with a *No connector found for connector id 'file-connector'* (I don't know if this is expected behavior)

Thanks again for your support

Hi Horia.

Right – connectors must be on the classpath of the engine (shared lib when using a Tomcat with a shared engine). Glad I could help!
