How to configure spring commonj workManager in webSphere liberty profile server 8.5

Question

I'm trying to migrate a spring web application to WebSphere liberty profile 8.5 from WebSphere application server 7. I'm getting "java.lang.NoClassDefFoundError: commonj/work/WorkException" at the application start up. I configured the data sources and common libraries using feature manager but couldn't find a way to configure WorkManager.

Can someone tell me how to achieve this?

Here is the exception log:

Answer 1

I had same issue. Fixed by adding commonj-twm.jar to application libs.

Answer 2

The Liberty profile does not support the commonj or asynchbeans programming models. Instead, it supports the JSR 236 programming model with the concurrent-1.0 feature. You will need to update your application code.
