ClassNotFoundException SpringConfigurationHelper

[franklin]

Hi all,

I'm new in Activiti and I'm facing a problem with Spring configuration. I try to configure my activiti-context.xml like this:

<?xml version="1.0" encoding="UTF-8"?>

But when I start the server ( Tomcat 6 ) I recieve this error message

I know that this error means that it couldnt find the class SpringConfigurationHelper. But my question is:
Where is this class? I try to find this jar but I have no sucess.

I'm working with Activiti 5.1 and Spring 3.0.3

Thank you all.

Classnotfound exceptions are always about missing libraries. Find the missing .lib file and include it in the classpath and it should fix the problem. Google the class to find the jar file.

You will probably require the activiti-spring dependency.

Hi all

In case, I was using the 5.3 version. I make an upgrade and work now.

Thank you all.
