Hello I had a problem of setting paths in Java.I setted classpath(C:\java\j2sdk1.4.2\lib) and path(c:\java\j2sdk1.4.2\bin) in system variables. But when i compile simple java progrm by typing javac Hell.java it is not working in compiling and telling no external and internal commands and batch files found.Why it is telling? kindly tell the solution for the problem whether there is any fault in settings or compiling(javac Hello.java).Recently i posted the same problem and some other guy gave me instructions to type as javac Hello.java but still it is not working,so please tell the solution.
