BPM Process with MailTask wont deploy

[jaco1]

I am using Activiti as part of WSO2.

I followed this tutorial https://docs.wso2.com/display/EI640/Working+with+Mail+Tasks. I can deploy a test process without a mail task and all works 100% until I add a MailTask. As soon as I add the mail task the bar file will not deploy and I get error. If I look in the log I don't see an error that explains why. Just that the parser has an error.

I made this test process and it also fails

Here is the error from the log.

What do I need to do to get a mail task working ?

[jaco1]

Any help with this simple issue? Why does the mailtask not deploy ?

I got it working. The jar files where in the wrong place.
