I\'m attempting to compile Java 1.4 code that was created by IBM\'s WSDL2Java on Java5 without recreating
Go to the Java Build Path in the project properties. Remove the existing JRE System Library Then Add it again i.e. Add Library-->JRE Lib--select jre--->Finish. Lastly select order and export tab select JRE Lib and move on top. That's it.
