[javac] bad class file: C:\bea12c\wlserver_12.1\server\lib\..\..\..\modules\features\..\javax.servlet_2.0.0.0_3-0.jar(javax/servlet/http/HttpServletRequest.class)
[javac] class file has wrong version 50.0, should be 49.0
[javac] Please remove or make sure it appears in the correct subdirectory of the classpath.
[javac] import javax.servlet.http.HttpServletRequest;

Answer 1

It seems like you are using a library which has been compiled with Java 6 but you have JAVAC lower than 1.6. I would suggest to upgrade your compiler to 1.6 .
