Java Applet and Html 5

Question

Hi I am trying to embed a java applet in a HTML 5 page. But I keep getting a class not found error.

I have 3 files all part of package applet in larger project. I compile the *.java files, then package up with the following command.

jar cfm0  DataUpload.jar manifest *.class

manifest file

 Manifest-Version: 1.0
 Permissions: all-permissions
 Codebase: *
 Application-Name: DataUpload

Sign and place the jar in root dir of the HTML page and call the applet with the following code.

<object type="application/x-java-applet" name="DataUpload" width="500" height="300">
  <param name="name" value="DataUpload" />
  <param name="archive" value="DataUpload.jar" />
  <param name="code" value="DataUpload.applet.DataUpload" />
  <param name="scriptable" value="true" />
  <param name="codebase_lookup" value="false" />
  <param name="mayscript" value="true" />
  <param name="plugindetect" value="1" />
</object>

Now I think its a problem with code because I was getting wrong name without the applet.DataUpload section. So I added the DataUpload As the base jar address.However no progress

Any help would be very useful

Change <param name="code" value="DataUpload.applet.DataUpload" /> to <param name="code" value="DataUpload" /> and make sure your applet isn't actually in a package. If your code is in a package, then your jar command needs to reflect that (you would need to preserve the folder hierarchy to preserve the package name).
