I don't know if anyone else is having the exact same problem as me but when I try to get jar programs from getjar or sharejar i get a content mismatch error and it won't download. however, if i download the jar file to my computer then upload it to a free account at hostj2me.com then i can download it just fine. why it works from there and not the sites themselves i don't know but its easy to do. like i said, the account is free and you can keep your jar files stored online. you can also see files other users have and you and they share the files you upload. you also have the choice to not list your files if you don't want to. anyways, again, hope this helps someone else as well.
