This is driving me up the wall. I have checked and rechecked spelling and paths. I have tried just about every combination of paths, including relative, absolute, and full http paths. I continue to get the following error when trying to load a
Java applet:
java.lang.ClassNotFoundException: AppletClient.class
at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
at
java.lang.ClassLoader.loadClass(Unknown Source)
at
java.lang.ClassLoader.loadClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source)
at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source)
at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at
java.lang.Thread.run(Unknown Source)
Exception:
java.lang.ClassNotFoundException: AppletClient.class
The HTML used to load the applet:
<applet width="100" height="100" archive="applet/myapplet.jar, applet/applet_dependency.jar" code="AppletClient.class">
<param value="blahblah" name="username">
<param value="false" name="codebase_lookup">
</applet>
The applet is in a relative directory, "applet", from the path of the current page. I have unzipped the jar file and can see AppletClient.class. Also, in the source of the project, it is spelled that way (casing and all). I have tried with/without the parameters. I have changed the names of the archive jars in the applet include tag just to see if I get a different error for bad file names (same error).
I have manually done GETs on the jars to make sure the server is responding to the requests (it is).
I have tried with and without the codebase tag, with all different varieties of paths (start getting bad "magic number" errors on those).
I know that this error sometimes pops up when a dependency fails to load, so it can be misleading, but all dependencies are present, accounted for, and are fetchable via manual GETs.
Between each and every attempt I always clear my cache in FireFox. These problems are reproduced in IE8 and Chrome as well.
Per my
Java Console from the browser, I am running
Java Plug-in 1.6.0_20. This is from the same machine that I develop the applet on, which runs fine via Eclipse.
Finally, I kicked on Fiddler2, and I don't see a single request for the jar files anywhere The host site is running from my Visual Studio debugger, so it's running on localhost. But I see the requests for all the other resources on Fiddler. Just... no Jars. ANYWHERE. I clear the log, cleared my browser cache, and did a ctrl-R refresh. And still, not a single Jar request on the Fiddler log.
I even did a delayed write (with JS) of the applet tag after the page loaded, once all the Fiddler activity slowed down. The element gets written to the document (and I can see the 100x100
Java error window), but not a single request shows up on Fiddler.
Any suggestions, before I go crawl into the corner and cry myself to sleep?
EDIT: From the
Java console, if I hit "l" (el) to "dump classloader list", I see something that looks like this:
Live entry: key=http://localhost:55446/BaseWebSite/,http://localhost:55446/BaseWebSite/applet/myappliet.jar, http://localhost:55446/BaseWebSite/applet/applet_dependency.jar, refCount=1, threadGroup=sun.plugin2.applet.Applet2ThreadGroup[name=http://localhost:55446/BaseWebSite/-threadGroup,maxpri=4]
