java program launcher

Hi there,

I want to know how to write a java program launcher for Windows.

It's a .exe file to laucher a java program. Just like the one Azureus
use.

Basically, it equals command "java classname", but when looking at the
process tree, you'll see the difference.

I think it's easy to implement for people who're familiar with Win32
programming.

Could someone tell me how to do it or send me a sample program.

Thanks in advance.

Here is the basic app Launcher. The rest is up to you

    DWORD LaunchApp(LPCTSTR szCmdLine, LPCTSTR szWorkingDir, bool bWait)
    {
        DWORD                dwRetVal, dwCreationFlags;
        STARTUPINFO            sInfo;
        PROCESS_INFORMATION pInfo;

        dwCreationFlags = CREATE_NO_WINDOW;

        ZeroMemory( &sInfo,sizeof( STARTUPINFO ) );
        sInfo.cb = sizeof( STARTUPINFO );

        BOOL bRet = ::CreateProcess( NULL,
                                    (LPTSTR)(LPCTSTR)szCmdLine,
                                    NULL,
                                    NULL,
                                    FALSE,
                                    dwCreationFlags,
                                    NULL,
                                    szWorkingDir,
                                    &sInfo,
                                    &pInfo );

        if (bWait)
        {
            WaitForSingleObject( (HANDLE)pInfo.hProcess, INFINITE );
            GetExitCodeProcess( (HANDLE)pInfo.hProcess, &dwRetVal );
        }
        else
            dwRetVal = 0;

        return dwRetVal;
    }

Maybe .. it is as like.

<code>
(This is not tested)

int APIENTRY _tWinMain (HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow) {

STARTUPINFO si;
memset(&si, 0, sizeof(si));
si.cb = sizeof(STARTUPINFO);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;

PROCESS_INFORMATION pi = {0};
BOOL b = CreateProcess (
NULL,
"javaw.exe -jar -your option your file.jar",
NULL,
NULL,
FALSE,
NORMAL_PRIORITY_CLASS,
NULL,
NULL,
&si,
&pi );

if (!b) {

return -1;
}
WaitForSingleObject(pi.hProcess, INFINITE);
CloseHandle(pi.hThread);
CloseHandle(pi.hProcess);
return 0;
}
</code>

The JDK sources do include the sources for the java.exe launcher which is
exactly what you want.
