QtJambi and Qt creator

mansi

Hello guys,

If I want to write a code in java Qt creator, google shows QtJambi as the solution.
From what I have understood, it provies java language bindings. I reffered this link "http://qt-project.org/wiki/Qt_Jambi".
I want to know :

Is Qtjambi and Qtcreator different ??
I am using Qtcreator for my development purpose but Unable to use bluetooth libraries ( tried with the bt chat example).I tried to install Qtmobility but it ain't working ( installation is failing everytime with different errors, not able to figure out )... So I am thinking of writing a java code using java libraries and compile it using Qt.
Is this even possible ?? Is Qt jambi helpful for doing this ??
If I install Qtjambi, will that affect my other projects in Qtcreator ??

Thanks a lot in advance,
Mansi
