Ummm... dude... I think your requirements are going to have to change... the MS JVM won't run any Swing stuff... ( or any other Java 2 stuff either... )

Though I'm not sure why it's not able to find your actual applet, it should be throwing an exception on "class JApplet not found" or some such thhing. Looks like you may have other problems with finding your class, in addition to impossible requirements... Only other thing I can think to check is the manifest file in your JAR file. Is it pointing to the correct class?

I'm still getting this error..
do you know if my class files should have been compiled with MS java in order for the MS jvm to recognise my files or not.

No... any java class compiled by any java compiler will work in any JVM ( well, as long as the versions aren't radically different, and as long as all the class files are found. )

From the error message you got, it looks like the name of your applet is misspelled somewhere... it has to match in all these places:


  • The filename of the java file.
  • The name after class in your java code.
  • In the manifest file of your JAR.
  • In the HTML code.


  • Also, remember Java is case-sensitive... if you named your class tagApplet in one place, and TagApplet in another, Java doesn't know what you are talking about.

The swing classes are mostly not yet supported by browsers (the same with microsoft additions). That means
you have to build a jar-file with all classes used by your applet (there
are tools for it) and then use the
archive="myJarForAllINeed.jar" as one of the applet parameters.
Thats what the problem looks like to me.

javac -target 1.1 MyJavaClass.java
...this will compile the class to a target version acceptable to the older microsoft JVM version.
