How to make run.bat connect with the jar file on the Start Menu of WinXp

I have written a file "new.java" and changed it into "new.jar";
I also wrote a bat file "run.bat" which content is as follows:
echo off
java -jar new.jar

In the same dir,when I double click the run.bat,the new.jar wil start,the effect of the jar file is that  a Dos command window is displayed.

I use a  software to make "new.jar","run.bat" and another file "help.doc" into a setup software.And you  can use the setup software to install the three files(new.jar,run.bat,help.doc) in some directory.
In the Start Menu of Windows Xp,there are three menus which are linked to these three files.

when I click the menu which is linked to the file of "help.doc",I can soon see the "help.doc" which is installed in one directory.However,when I click the menu which is linked to the file of "run.bat",I can not see the Dos Command Window.The “new.jar" file seems not to run.

so how can I make the menu in the Start Menu of Xp to link to the "run.bat" file correctly so that I can start the "new.jar" file  and see the Dos Command Window?

Thanks in advance.

You should not need the run.bat :
a proper installation of JAVA (JRE) on Windows sets a Registry link from  .jar to   javaw,
so you can just click a .jar file.

If this is not the case you might install that:

For MSWindows2000:
- Windows Explorer -> Tools -> FileTypes;
Scroll down till you find JAR and select it, then press the Advanced button.
This should pop up a list of Actions, and you'll probably just have one 'open'. Select 'open' and press the 'edit' button on the right. You'll then get (another) dialog showing the action name and the application used to perform the action, something like this:
   "C:\Program Files\Java\j2re1.4.1_01\bin\javaw.exe" -jar "%1" %*

Right! If you want to make a .jar file out of a .java file (one - to - one) you should do:

javac new.java

jar cvmf Manifest.mf new.jar new.class

Manifest.mf should be a text like:

     Manifest-Version: 1.0
     Created-By: 1.4.2_03 (Sun Microsystems Inc.)
     Main-Class: new
                                                              <----------------------- this is an empty line! do not forget to add it.


;JOOP!

And one remark:  as classes should have names starting with a Capital letter, your class should be
     New    rather than    new

As a result all files involved should have names  New  in stead of new.

Second remark:  in the above example you add 2 files to the jar: a class file and a manifest.
Every next addition (class files, pictures, sounds ... ) can be added without necessary changes
to the manifest.

The purpose of the manifest is that JAVA (javaw) can find where to start for a "main( )" as the .jar doesn't have
to have the same name.

;JOOP!
Finally:


Start->Settings->Task Bar & Start Menu->Advanced->Add   .....   I think you can add the command

                              javaw -jar new.jar

Don't forget to supply the right PATHs to javaw   and   new.jar  respectively.

Indeed, if you never installed JAVA on a fresh XP system, you should download
         j2re-1_4_2_03-windows-i586-p.exe
that's the latest release, from
          http://java.sun.com/j2se/1.4.2/download.html
(3rd section on the page).

I think that a split points would be more appropriate, because objects, GrandSchtroumpf and me
