Issue
You get a ClassCastException while trying to read a previously loaded object. You have a compiled class under /apps/abc/classes. You load an object from this class into the session by using your servlet which is also compiled in /apps/abc/classes. Then, you try to read the loaded object in a JSP from /apps/abc/components/examplecomponent.
Solution
Place your class file into a higher level in the classloader hierarchy. See docs.day.com for detailed classloader description.
Additional information
This issue is possibly the result of a classloader issue. The object loaded in the first place is not visible in the second place.
