Default Need help with .jar files

Please Login to Remove!

Hi guys, I'm new to the forum but I did use the search function before posting this thread.

I have a blackberry pearl 8100, and I want to install some .jar game files. I tried installing it by saving it to the SD card and navigating to it with the blackberry. I can find the files fine, but when I go to install it, it says, "Unable to display file" and follow with the directory. Blackberry sees the files, but it doesn't run the files. I've also tried it with .alx and .cod file type, but I just get the same type of error.

Do I need to install some other software before I can install .jar files?

Thanks

Can you just install the games OTA (over the air)? Do you have a data plan?

I've run into the same issue before. Never been able to install .jad/.jar from the method stated.

I would install the OTA method because one of the site had Zelda. The thing is that I don't have a data plan.

Does it give you the option to download it to your desktop? You can then use BB DM's app loader to install it onto your device.

They do. I'm very new to BB, so how do I get the DM and use the app loader to install it into my device?

BlackBerry DM usually comes on the CD when you first get your BlackBerry device. If not, you can go to the BlackBerry website and download the desktop manager from their Software section.

Once you do that, open up DM, and select APP LOADER. Find the file that you downloaded to your computer. It's been a while since I've done an install via the computer so sorry for the somewhat less detailed anwer.

Note too that you need the .alx and .cod files for installation via DM.

Is DM the same as desktop software, and does it matter which version I use (4.x)?

So are you saying that if I try to install the .jar file from DM, I'll also need the .alx and .cod for that .jar file that I'm trying to install?

Yes, DM is the Desktop Manager, and any of the recent ones should work.

You will only need the .alx and .cod files; .jar is not required.

So if the site only has .jar files then I'm screwed?

Unfortunately yes. I think .jad/.jar files were mainly intended to be OTA installs. Some people have had luck installing those types of files using the method you described, but I think its hit and miss.

Default Converting .jar files to .alx files.

I am fairly new to my BB and have viewed quite a few of the posts regarding the conversion...but don't get it. For some reason when I open the conversion it tells me to find the .jde file, but I can't find it. There has got to be a better way to install some of these .jar files. If anyone can give me some hints on how to do this...I would greatly appreciate it. Plan on taking a trip and having some games would be nice for the drive. Thanks
