Are you sure you're using the right installation files? The error message just says that it cannot find the stand-alone application in this files.

Hi everyone
That's my first post
I got your same trouble
"..Virtual machine bla bla"
but ,perhaps, i've resolved making prompt command

-Start ->Run type CMD press enter
-go to filename.jar folder
-run java filename.jar
-copy main name class just after ":" without "/jar"
Example
java hiworld.jar
Exception in thread "main" java.lang.NoClassDefFoundError: hiword/jar
Your main class is "hiword"
-run java again and write: "java -cp filename.jar YOUR_MAIN_CLASS" (main class should write in capital letters)
Example
java -cp hiword.jar HIWORD
For info switch "-cp" find right class folder
U may create a batch file and save it in same directory of JAR file Remember ext "?????.BAT" Example hiworld.BAT
Before to try my application i've removed any java programm from task menu but i suppose that is not be required

Best Regards
B.-

Hi, folks.

Let me tell you my experience of the notorious "Could not find the main class. Program will will exit" message from Java Virtual Machine Launcher invoked by javaw.

I had 2 Eclipse Java project; namely A-project and B-project. B-project was dependent on the artifacts of A-project; B required the jar of A.

I wanted to create Windows EXE of B. I selected JSmoothgen to create the EXE which wraps an executable jar.

I thought I had better to create a single jar which contains classes both of A and B. So in the build.xml for B-project
(1) compiles B classes
(2) unjars the jar file of A-project
(3) create a jar containing A and B classes, append MANIFEST.MF with Main-Class declaration.
(4) run JSmoothgen to wrap the executable jar into Windows EXE.

I did all those steps on JDK1.5. By double clicking the produced EXE, I got that sad message.

I happened to uninstall the JDK1.5, then reinstalled the JDK1.4. I did the B-project build to get a rebuilt EXE. Double-clicking the icon, WOW, it worked fine!

Now I will tell you why. In the build.xml of A-project, I did NOT specify "target" option for <javac>. The <javac target=".."> option specifies the version of target JavaVM. In the build.xml of B-project, I DID explicitly specify target="1.4". This inconsistency was the root cause of my problem.

When I do the buid for A and B in the JDK1.4 environment, I got 1.4 classes for both of A and B. All the class files contained in the final executable jar (and EXE) were targeting to JavaVM 1.4, Ok.

Once I move to JDK1.5, the A-project classes are compiled into JavaVM1.5 format because the build.xml for A project missed "target" attribute for <javac> therefore defaulted to "1.5". On the otherhand I got the B-project classess compiled into JavaVM1.4 format because the build.xml for B explicity specified target="1.4". Then I got a ugly jar where some classes are 1.4 format classes and others are 1.5 format.

Sorry for the Java Virtual Machine Laucher, the jar I passed to you was just corrupted.

Hey, I've had this problem for months, and I just stumbled across this message board as I was looking for a way to fix it. Every time I started up my Dell with Windows XP, I got the aforementioned "Java Virtual Machine Launcher: Could not find the main class. Program will exit" message.

I tried Matthaias Neumair's solution (listed on page 1 of this thread) to no avail. I then ran Lavasoft's Ad-aware, again without success. Finally, I ran SpyBot and the anti-spyware program that comes with AOL Version 9.0 Security Edition. None of these solved the problem.

The only way I managed to get rid of the pop-up was to go into the Control Panel, select "Add/remove programs," and delete all of my java-related software. After I did that, and restarted my Dell, I went to Java's website and downloaded the most current version of the software, as some of the previous posts recommend.

After one final restart, my computer is pop-up free, at least for now.
