Hi Java X-perts,
Still learning Java... I am making some experimtnes decompiling - compiling and back. One of the decompiled Java classes generates a few errors, when I compile it back WITH NO CHANGES:

Those are the lines and their errors:

import netscape.javascript.JSObject;  ---> package netscape.javascript does not exists

JSObject jsobject = null; ---> cannot find symbol

jsobject = JSObject.getWindow(o);   ----> cannot find symbol

==================================

I am using JAD for decompilation and it works fine for all other files. I cannot understand what is wrong as I have not made any changes to the code.

Thanks

-A-

Compile your app


javac -classpath %JAVA_HOME%\jre\lib\plugin.jar;. *.java

(if you've set JAVA_HOME as i recommended earlier)

It is even worse, it gives me 9 errors instead of 3.

1. java.applet.Applet is already defined in c68
2. a few similar errors - canot find symbol (variable super and class JSObject)

What is wrong?

Well you *are* likely to get errors from decompilation/compilation exercises.

If you post it somewhere public,i'll see if it can be compiled
