回答1:

Your JSP is too large / too complicated. You need to refactor it

We tried refactoring but its not working are there any alternate solutions?

No.

The problem is that there is a hard limit imposed by the Java virtual machine specification on the number of bytes of bytecode in a compiled Java method. (Specifically, the classfile format uses a 16 bit number as the sides of the method's code array.)

Java compilers are not able to automatically split a method that is too large into sub-methods. You have to do it yourself at the source code level.

With JSPs, the JSP compiler translates each JSP into a class with a single (large) Java method, unless you can refactor it by either moving some of logic into separate methods, classes or ... JSPs using "dynamic includes"; see https://stackoverflow.com/a/5484509/139985.)
