Some phones are very picky when it comes to file downloads and OTA installs. For these phones, a file having a .jad extension is not enough for the phone to accept it as an actually jad file. They require correct mime-types for the file extension before accepting it.

So you have to add/edit server settings, to add mime-types for the filetypes you which to be able to download/install.

Here are some examples for mime-types:

.jar application/java-archive
.jad text/vnd.sun.j2me.app-descriptor
.mmf application/vnd.smaf
.nth application/vnd.nok-s40theme
.png image/png
.class application/java-vm
