    Main Class not found problem

    I just made a jar file from an application/applet(it can be run either way) that I wrote. I followed all of the directions on the tutorial in cjards signature. The class that runs my program is called Runner, so in my manifest file I put Main-Class: Runner and then I pressed enter. I typed in jar cvfm SPX.jar mf.txt Saterasoft/ and it made the jar file. When I double click on the jar file, a pop up window informs me that the Main Class cannot be found. Does anyone know why this is happening?

    read the tutorial more closely.. you called the JAR command from the wronf directory, and as a resukr your jar file is messed up inside

    i,e, there is a very big dufference between these :

    c:\java\FINAL\> jar cvfm ..\MYAPP.jar ..\mf.txt .
    c:\java\>jar cvfm MYAPP.jar mf.txt FINAL/

    The problem I had with the tutorial is that when I tried to use the jar command in the Final\App folder , I got the error that jar was not a recognized command so I attempted to do it from the java folder and I keep getting that error.
