Actualy i think it's a bit more complicated
you also need to start logging.
here is how i do it with java reflection
File configDir = new File(startDir, "WEB-INF/config");
System.setProperty("mmbase.config", configDir.getPath());
//start logging
Class clazz = c.loadClass("org.mmbase.util.logging.Logging");
Method method = clazz.getMethod("configure", new Class[] { String.class });
method.invoke(null, new Object[] { configDir.getPath() + "/log/log.xml" });
System.err.println(clazz.getName());
//init mmbase context
Class mmbaseContext = c.loadClass("org.mmbase.module.core.MMBaseContext");
Method mmbaseContext_init = mmbaseContext.getMethod("init", new Class[] {});
mmbaseContext_init.invoke(null, new Object[] {});
//get the mmbase module this should start mmbase
Class mmbase = c.loadClass("org.mmbase.module.core.MMBase");
Method mmbaseGetMMBase = mmbase.getMethod("getMMBase", new Class[] {});
mmbaseGetMMBase.invoke(null, new Object[] {});
//get the mmadmin module and way untill it's loaded
attached a "runner" that start mmbase command line (after loading required jars from
