Wait for a program to run

[aquarius_kasuia]

Hi all. I have one problem:

I´m using javassist in a program I´m developing, well to the point:

I have a GUI, the users uses this GUI for some configurations and press the PLAY button. When the user press it I do this:

//get the Default ClassPool
javassist.ClassPool cp = javassist.ClassPool.getDefault();

//Add the classpath of the system to the classpool
for (int i = 0; i < vstringClassPath.length; i++)
cp.appendClassPath(vstringClassPath);

//Initialize a Loader and call the Controler
javassist.reflect.Loader loader = new javassist.reflect.Loader();
loader.setClassPool(cp);
loader.main(new String[] {"Controler"});

The Controler make some work with the paremeters the user has chosen and call the program the user has specified( I have a program that runs another program).

The user program is not in the classpath that´s why I had to put the User´s ClassPath in the loader ClassPath.

One of the things the Controler does is make some classes the user has chosen reflective.

After that I run the user program. Code above:

//Get the parent ClassLoader
javassist.reflect.Loader loader = (javassist.reflect.Loader)Controler.class.getClassLoader();

//Make the user´s class reflective
for (int i = 0; i < classList.size(); i++)
loader.makeReflective((String) classList.elementAt(i),
"InjetorFis",
"javassist.reflect.ClassMetaobject");

//Run the system
loader.run(mainClass, params);

This works ok with almost everything.


Now the problem: when the user has a program that creates another GUI the run method return after the GUI was created and my program terminate. I need it to stop there and wait the user to close his GUI.
I have tried things with Threads but I couldn´t make it stop there.

I hope I could explain my problem well.

Thanks for your time, javassist is very good!! I hope someone can help me.

In general (with/without Javassist), the Java GUI is executed by a
single thread dedicated for GUI. This thread is different from a thread
running main().

Since your program uses the GUI thread for running another user
program, main() of that user program is also run by the same
thread as GUI's. I guess that this configuration might confuse
the GUI library.

Your problem might be solved if the button-pressed listener
starts a new thread, which executes Loader#run().

I'm not sure that this way is correct but hope it helps.
