Not able to run java app on this phone. - Samsung B5722 Cell Phone

Yep! Jar is Java Code. Your App may have been written in Java and can't run without a Java interpreter running in the background.
Couldn't tell you where to start. Someone familiar with programming may be able to help.
But you haven't identified the phone or it;s OS.

Java is a programming software used in many areas like websites, cell phones apps and many more. Java scripts used to desigh how the web sites interact with the viewers. Java also used to create apps used in the cell phones. These apps can be designed to solve certain problems.So when someone says they need to create a solution using Java, they might refer to the fact that they need to create a new app or redesign how an app should respond to the commands.

if you want to run Java Games in your phone.
your phone shoud support Java app if it wont support java games will not come

you can only install and play java games by downloading the java games from internet directly from your mobile's default browser. you can't install java apps from memory card or pc. but please don't forget to rating my solution.

You have to download java apps for this phone & you also need a micro sd to store the apps. Brothersoft.com has tons of java apps, some work & some don't you just have to experiment. Once you download & save the file you just click the install link. You can then find the app under Java on the main menu.

Not every java app will run on every phone. look for app, that is made for your phone.

Me too there seems to be no option to install the files, it just doesnt undertand jar/jad files and theres no way to copy them to the apps folder

you need to reset your phone, that might solve the problem. a full master reset should work.
