editing java class files Can't Post
Ok my I have this java class file (not rs) that I wanted to edit and save it, and reload it into the game. So I downloaded dj java decompiler and loaded the script. Edited it saved it. Put it back in the appropiate folder, but when I load the game back up the files are still the same. I asked my friend who does this alot and he said I have to compile the java file or recompile the class file into a new .class one. I dont understand that compile tut up there. So does anyone have a official compile program or knows how to use the compile option in dj java decompiler because I get a error when I try. Or you could explain the tutorial above on compiling. It would be much appreciated..thx.

If you open up a .class in DJ, it will output a .jad. Thats a decompiled version, but anyways, you can just open that up, and save it as blah.java.

Then when you put it back in the JAR, you cant use Winrar, you need to use jar.exe, whick comes with JDK. You can make a batch file like this
-----
@echo off
jar cf JARNAME.jar *.class
pause
-----
But yes, you need to compile it. Ill look at the tutorial real quick, and edit this.

EDIT: I look at that tut, and it assumes you have JDK installed. Check out www.java.sun.com, or Downlaod JDK from here: http://java.sun.com/j2se/1.5.0/download.jsp

Once you instal that, I can help you set up your Env Vars, if you want, but you dont need to.

Whenever you decompile them, edit them and save them back as .java files. After you are done compile them by using this code:
"@echo off
javac *.java
pause"

without the quotes and then re-implement it into the game. That should work. Any more JAVA questions you can contact me on MSN at raptman123@hotmail.com
