In general it is good practice to separate logic and layout. JSP are usually for providing the view / layout. Logic / java code should be used in servlets and other java classes (e.g. models). So it is recommended anyway to move java code from JSP to java classes. See https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller Greetings, Thomas
