如何从带有embed标签的子文件夹中加载Java applet类？

Question

I have a Java Applet as a single class file (No JAR file) in some sub directory and I want to embed it on a HTML page which is in a different directory. And I want to use the embed tag for it. But I can't get it working. This is my code so far:

<embed type="application/x-java-applet;version=1.6"
       width="512" height="512"
       code="subfolder/MyApplet.class" />

According to the Apache log file the Class file is loaded but it can't be started. Java says there is no class with name subfolder.MyApplet . So it treats the sub directory as a package name. A codebase parameter (No idea if this is valid for embed ) doesn't make a difference. Maybe there is some other badly documented parameter to specifiy a code base directory from which to load the classes?

Please note that my question is not about how to embed a Java applet in general. I know how to get it running with the deprecated applet tag or the object tag and by packaging the class into a JAR file. My question is how to get it working in exactly this specific situation:

• No JAR file, only single class file.
• Class file is not in the same directory as the HTML page.
• Using embed tag.

Answer 1

Consider using the 'codebase' tag when using the 'embed' tag. For example,

   <embed type="application/x-java-applet;version=1.6"
       width="512" height="512"
       code="MyApplet.class" 
       codebase="subfolder/"/>

You should be able to use relative and absolute paths in the 'codebase' tag.

Hope that helps...

Try following:

<embed type="application/x-java-applet;version=1.6"
       width="512" height="512"
       codebase="subfolder/"
       code="MyApplet.class" />
