Hi all

[--jubs-->]

Hi all, I just joined this group... hope I can be of any much help..

I have this problem with applets, when I run it on the appletviewer is
doesn't show any error but when I deploy the html to a server and acess
it from a browser it shows ClassFormatError : Truncated classfile. I
googled for it and some sites say its a bug in java 1.4 & 1.5. I tried
almost everything and Iam exhausted... .Other sites say I should
recompile and then deploy (doesn't work). One thig though my applet has
a lot of threads and inner classes. Does this have to do anything with
it??

Sincerely
jubs

To me this sounds like a problem with the way you transfer the jar/classfiles
to the server. Have you verified that the file(s) on the server are identical
(not just the same length) to the ones on your local system ?

You did set your FTP client to binary transfer, didn't you?

how do u do that???

If you use FTP from command-line, type "bin" (as opposed to "ascii")
after connecting to the server.
If you use a graphical FTP-client, there should be a toggle ("binary"
vs. "ASCII") somewhere in the GUI.

Every FTP utility does it a different way. Poke around in options for
auto/binary/ASCII. ASCII flips the line endings to match your server
convention e.g. \r\n -> \n for a Unix server. But if you upload a
class file that way or a jpg, it will scramble it.

Are your classes jar'd?

If so, the class files themselves are not being truncated.

Note that
- Your classes will need to be jar'd for JWS.
- If it works with Jar'd classes for JWS, it should
also work for Jar'd classes as an applet.

[ And JWS'd applets suck. E.G.
