Hey, I know very little about Java. I do however, know Batch very well. My dilemma is this: I'm working on a server launcher batchfile, and I have the issue of a Java command pausing the script until the whole command is executed and Java says that it's done. For example... Code: set something="> " Java -jar craftbukkit.jar Xmx3G Xms3G -o true op Notch PAUSE Obviously this will not simply tell the server, a Java program, to op player Notch, because it waits on Java being done. So I plan on opening a separate Batch script right before running the server, and then that Batch script will tell the server what needs to be done. Code: tellserver (.bat) Java jar etc... My actual question is this: Is there a Java command (one like -jar, which can be used in a cmd prompt) which will tell a currently running program a certain thing, or will I need to ask a Java programmer to write me a class to do that and call on that class? I'm trying something else, hopefully it will work. Edit: No, it didn't work. Bump Hoping to have an answer soon, as this is effecting the release of my next version EDIT by Moderator: merged posts, please use the edit button instead of double posting.
