Hi,

I guess are test application is pretty short, so I guess the MCR is closed together with your application. In order to prevent this see here:

Hi,primarily thank you,

I looked your link,so i think we can not use matlab graphic method with JFrame and Java Window Application or is it posssible?

Last question is that what's MCR? How can i open it with application? Because normally when i run my application,it soo slow on the first try.. i wonder it is related with MCR?

MCR is MATLAB Component Runtime. It is more or less MATLAB without the command line or fancy display. The first time you start any application it needs to unpack the Component Technology Files and start up MCR, so Yes, that tends to be slow. And then times after that, if it finds the files already unpacked and verifies they are unchanged, then it will not need to unpack them again but it will still need to start MCR. Starting MCR is, in itself, very close to the same time as starting MATLAB would be.
