i have a problem and i dont know how to fix it: Activiti cant instantiate my class. After a short research i saw a solution which told me to include my classes inside the web-inf/lib folder but that didn't work for me. I restarted the tomcat and did everything explained here.
I had working with this tutorial to learn how to create and deploy new processes, because it seems the best way to me.
Don't think it will make a difference if you create the jar using eclipse export JAR or maven.
Can check the content of the jar-file, to see if it contains all folders that correspond to the fully-qualified classname in your *bpmn20.xml file? Also, double-check that the jar is present in the location stated earlier. That's all I can think of…
What's the exact stacktrace? Is the cause a ClassNotFound or a NoClassDefFoundError?
