Problems with Camunda Spin on UNIX camunda-spin-dataformat-all-1.0.0.jar

[Melissa Palmer]

Hi All, 

I'm experiencing some oddities with the 'camunda-spin-dataformat-all-1.0.0.jar' when deployed on a Unix environment. 

We have the following setup:

- apache-tomcat-7.0.57 

- java version "1.7.0_25"

- bpm-platform.xml configured to use SpinPlugin 

      <!-- plugin enabling integration of camunda Spin -->

      <plugin>

        <class>org.camunda.spin.plugin.impl.SpinProcessEnginePlugin</class>

      </plugin>

- tomcat lib folder contains spin jars (and all the other camunda related jars that are needed)

camunda-engine-plugin-spin-7.2.0.jar

camunda-spin-core-1.0.0.jar

camunda-spin-dataformat-all-1.0.0.jar

camunda-spin-dataformat-json-jackson-1.0.0.jar

When starting up the server we are seeing the following error (NOTE: exact same setup on a windows box is not causing any issues.):

Hoping that someone will be able to help me out here with this one? Seems very odd! 

Thanks

Hi Melissa,

you should deploy either camunda-spin-dataformat-all-1.0.0.jar or camunda-spin-dataformat-json-jackson-1.0.0.jar. The first contains shaded versions of

the dependencies. For the second one you have to add the required dependencies to your classpath.

Cheers,

Sebastian

Thanks Sebastian, that has helped and sorted out my issue. 

I am still failing to understand why this was behaving differently on Windows vs. Unix? Any ideas there? 

Thanks

Melissa
