Please ask a question only once and this question should actually be posted on the user forum.
The exception says it all, it's not able to find the SpringProcessEngineConfiguration class, which is part of the activiti-spring JAR. So it looks like the classloading isn't working as expected in your WebSphere.

Best regards,

I have added the jar files already there, which i have mentioned in the jar list. Please note that. Even then it was not working. That's the reason i posted this query. I wanted to know where i need to place the jar file. Can you guide me on this?

Use maven and include ALL dependencies activiti-engine and activiti-spring has. The noclassdef indicates a dependant class of the activiti-spring class is missing…

Thanks for your comment. I added the following files in the same path in the lib folder of websphere, commons-email-1.2 jar, mail-1.4.1.jar, common-langs-2.4.jar, commons-logging-1.1.1.jar, joda-time-2.1.jar, slf4j-api-1.7.2.jar, jcl-over-slf4j-1.7.2.jar, aopalliance-1.0.jar, commons-dbcp-1.4.jar, commons-pool-1.5.4.jar.

Now it is working.

But can you please state why do I need these many jars to make the activity run?.

- The commons-email is only needed if you use the email-task. (mail + commons-mail)
- Commons lang is a real small util-lib.
- SLF4J is a very common logging library. We need the JCL-over-sfl4j to make other liberaries we use, log over slf4j even though they don't know it. These are required and were probabily the culprit on this issue.
- The dbcp and commons-pool is only required if you delare a connection-pool using DBCP. If you're using another pool, you can remove those.
