I added the required API,libraries,and run it in the device directly
what is the problem ????

And what errors or panics you are getting?

[QUOTE]I want to uninstall my application programmaticly
...
[code]// Check for [COLOR="Red"]MIDlet[/COLOR] name in the file
err = buff.Find(_L("Application name[COLOR="Red"].sis[/COLOR]"));[/code]
[/QUOTE]
???

Are you sure that you are trying to delete MIDlet (J2ME) application?

I need to uninstall .sis application not jar
nothing occur neither error nor panic
I modified this code to uninstall sis
is it only for java midlet??????????????

Please verify if you have added sufficient capabilities to make use of this API.

yes I added CAPABILITY TrustedUI

Can you put logs and check if it is able to parse and find the application name properly.
