This line of your makes no sense. It is actually evaluated to:
As you can very well see, the
servlet then tries to invoke that method on your beanObj and throws an exception.
Also, if you're using JSTL, then there's really no need to use "logic" tags.
If you can clearly state what it is you need to achieve conceptually, [copy contents of one arraylist into another?], then it'll be much easier to assist you.
