Truncated Class file error

843807Oct 8 2008 — edited Jul 28 2009
Hello Everyone,

I have written an applet for a website and I am trying to add the applet to the website. When I made a dummy html file on my machine the Applet opened in all the browsers. When i did the same on the server, it gave me the following error when I tried to open the webpage.

java.lang.ClassFormatError: Truncated class file

The server does not have JRE installed on it and I am trying to load the applet using a JAR Archive. Is this failing because of no JRE on the server? I even tried giving the codebase as a folder which contained all the class files in it. This give me the following error:

java.lang.ClassFormatError: Incompatible magic value 1008813135 in class file applet

As I said both solutions work on my local machine (Mac OS X 10.4.11).

Please help
Steve
