Starting a Java process from a C++ process

How can I start a Java application from within a C++ process?

I don't want to invoke just some parts of the Java application, as could be done with JNI, but actually run the whole Java application.

would system("your java command") work?

Yes, you can follow the steps at this link: http://java.sun.com/docs/books/jni/html/invoke.html

Note that the sample invokes the "main" method of the loaded class so it would be just as if you did something like java -jar app.jar where the manifest in app jar specifies a main class that loads and starts the app.

Sure, easily:

system("java ClassName");

You can certainly get fancier than that, adding environment variables for CLASSPATH or whatever else you need. The details of doing so may be moderately system dependent, however.
