I have to compile a java file using builtin struts classes. so I used the javac -classpath option. is there any other do-it-once and use javac without -classpath option. is there a way to tell the compiler to find those classes in struts-core.jar jar file without using -classpath, like say, add the jar file to where bootstrap or extension class files reside. by doing so we can avoid -classpath option.
