[wildfly-dev] Cassandra Subsystem

[David M. Lloyd]

Well, I have a bias of course, but it seems to me like you could just 
add Cassandra and its dependencies as modules and then launch it like this:

     String javaHome = System.getProperty("java.home");
     ProcessBuilder pb = new ProcssBuilder(
	javaHome + File.pathSeparator + "bin" + File.pathSeparator + "java",
         ...jvm args...,
         "-jar",
         "jboss-modules.jar",
         "-mp",
         "modules",
         "org.whatever.cassandra",
         ...cassandra args...);
     ...set up I/O redirection here...
     Process p = pb.start();

How would I pass the classpath to the subprocess? Is there a way to get to the CP, similar to the way an URLClassLoader exposes it? Or how could it be achieved with JBoss modules?
