    .java to .jar file

    As a side note to Easy Rhinos comment, you can only jar .class files, meaning that you need to compile all the .java files and them jar the .class files resulting from the compilation. Example:
    Code: javac Test.java jar cf Teste.jar Test.class[/quote]

  3. .java to .jar file

    if you know the manual then you know you dont put the code in the program, you convert all of your java class files into a jar file using their compiler.

    jar files

    Fixing .jar file opening on Windows requires two steps:

    • Open the Control Panel, and chose "Default Programs - Associate a File type or protocol with a program". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)".
      A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button.
    • Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. This is normally: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

    I Hope this Answers your Question!
