can you try downloading a jad first, from another website and server, then if that fails, try the jar
that might help prove it is your phone and not the server
it sounds like something similar to this is going on
but i dont know why
If you want to serve file types that are not supported by the default mime.types file, you can augment that file with your own definitions. To do this, create a file called .htaccess in the directory where the files you want to serve are located. In the .htaccess file, type:
AddType mime-type .ext
where mime-type is the MIME type and .ext is the file name extension you intend to use for files to be associated with mime-type. You must include a period (.) before the extension. You can list several exts separated by blanks. For example, see the image/jpeg entry above.
If you are not sure what mime-type and .ext to use, do not create a .htaccess file. Instead, send mail to your Webmaster or to email@example.com to ask for help.
Save the .htaccess file and store all ext files in the same directory. Then, all files in the directory that end in .ext will be mapped into mime-type and handled properly by the server.
