Integer.parseInt(String, int) line not available

I have written a program and made it run on tomcat server. It does not give any output but when I debug the program it is showing me the following error. "Integer.parseInt(String, int) line not available". This line is not available in the program. Even then this error is shooting up with a source not found and edit source look up path button. I have tried various solutions like uninstalling and installing the server again. But that did not help. Please try to help me out. Thanks in advance
