How to Run Multiple Java applications at a same time in a Java Phone

Its almost impossible to run 2 or more than 2 applications in Java phones. But I found a solution which may help you to combine two or more than two JAR application to a single JAR midlet to run in non-multitasking phones (Example: Nokia s40 phones).

I will discuss the most effective method you may implement on creating a combined JAR midlet with two or more JAR files. I will post an update for second method.

Follow the simple steps below to combine two or more JAR files to a single midlet.

• Go to http://multime.org
• Click on Register and fill the form to create a new account and login

• Now click on My midlets
• Click on Upload Midlet to upload two midlets you want to combine or you may use Add by Link if you have the direct download link of the midlet

• After you done, click on My projects
• Click on New Project and name your project and click OK

• Click on the listed project you just created (i.e. My Project)
• Click on Add midlet and select the midlets by clicking on green coloured '+' button to add the desired midlets. (You can also add the same application by clicking twice)

(You may click on Permission button to set permission on your midlets, certify etc or don't touch that if you are not sure whats going)

• Click on Build button to build the new combined midlet

You will be given download links for both Jar and Jad file of the combined midlet if everything goes fine.

Download and test it on your phone. If it didn't worked then use the comment box below, I will be very happy to help you out.
