For many of us, it's really a pain debugging a UI, especially a JSP page without any special add-ons in eclipse. And here is a simple solution for it. Create a class named Test and a public method foo() in that. Now put a breakpoint in the entry of the foo() method. Insert foo() invocation in the JSP just before the point where you want to start the debugging. For Eg. <% Test.foo()%> Start the debugger in eclipse. Now once you execute your flow, the debugger will suspend the thread at the entry of foo() Press F7 and guess what you will be taken to the JSP page from where you can continue the debugging in the JSP itself
