Issue with camunda-bpm-mail-core

Sudhanshu_Sekhar · May 21, 2018, 3:59pm

Hi Team,

We are using Camunda Enterprise Edition Version 7.6.2. Which is deployed on web logic server.
We are using java 6. When I place “camunda-bpm-mail-core-1.0.0.jar” jars in lib & start Camunda Engine, it fails with exception :

<Unable to set the activation state to true for the application “Camunda Engine”.
weblogic.application.ModuleException: java.lang.UnsupportedClassVersionError: org/camunda/bpm/extension/mail/send/SendMailProvider : Unsupported major.minor version 52.0

Any suggestion is appreciated.

Thanks,
Sudhanshu

Hi @Sudhanshu_Sekhar,

the problem is that you’re using Java 6
The Camunda mail extension requires Java 8.

Best regards,
Philipp

Hi @Philipp_Ossler, Is there any camunda mail extension jar available which supports java 7 ?

Nope. If you really want to use the extension with Java 6/7 then you can fork the repository and switch the Java version. I guess that the code adjustments are not so much.

@Philipp_Ossler, Which repository you are saying about??

I mean the GitHub repository of the extension: https://github.com/camunda/camunda-bpm-mail
