The good news is that you do not have to edit any of this code to make your own custom launcher. It contains method signatures for the functions in java_md.c. This is the C header for the java_md.c file. This is the platform-specific launcher source code in C. It contains method signatures for the functions in java.c. This is the C header for the java.c file. It contains common code across platforms. This is the shared launcher source code in C. Let's have a look at the files in the launcher subdirectory: Unzip it into a directory called src under my JDK home and point my Java IDE to it for debugging

Unzip it and you will find several directories, including the launcher directory. In your SDK installation directory ( C:\j2sdk1.4.2_04 on my machine), there is a file named Of course, this is not the complete source code to the JVM, but the source code for the It's a little-known fact that the source code to java.exe and javaw.exe are included in embedded in a jar file in the manifest.Īgain, the performance difference is minor, but it might still be worth it to you to eliminate every extra bit of Performance compared to an executable jar file distribution such as JEdit shouldĪlso be better because startup parameters are compiled into the launcher vs. JVM, shaving a few milliseconds off the application start might be worth it to you. The amount of time savings should be negligible, but given the slow startup time of the A native launcher is faster than a batch-file launcher because interpreting batch files is slower This is the weakest of the three arguments, but worth mentioning for those of you that are obsessed with performance

Options for deployment range from fancy automated installers, to executable jar files, to "copy and run". The second common problem is that a custom icon is not provided. This has an additional benefit of hidingĬertain details about how your program is launched, such as the CLASSPATH and the " main()"Ĭlass. This is indicative of a batch file that is calling one of theĭefault Java launchers ( java.exe or javaw.exe).
