I am writing code for an animation program and I have a problem. I need to set up core dumping. NetBeans is saying this: Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

What do I do to start core dumping? Is there anything in terminal or at the string args[]?

Note: The program fails to run completely, so I do not know what is occurring.

    Read the error message... it tells you EXACTLY what to do. – Marc B May 04 '13 at 00:25
  • Also, unless you are debugging Java itself or maybe writing native code, you normally don't need to inspect core dumps. – Thilo May 04 '13 at 00:29

    Marc B - I would not have posted a question if I read what it said and it worked, I am not completely incompetent. – I have too many problems May 04 '13 at 00:31
  • @Ihavetoomanyproblems: sorry about that, then. You should have mentioned what you tried, though. A lot of people on Stackoverflow would not have bothered to follow those instructions in the error message. Core dumps on OS X seem to be a bit involved, I hope the linked questions help. – Thilo May 04 '13 at 00:33
  • Thanks a lot for your help, thilo. I apologize for my appalling behavior, I was unaware that people actually did that. Also, those links did help narrow down what wasn't my problem. Thanks again – I have too many problems May 04 '13 at 00:35
  • You're going to have to be a little more detailed with what's happening, or specify that nothing else happens. I think, though, that if you try and run a program and it fails, your JVM is probably crashing on start. –  May 04 '13 at 00:40
  • Nothing happens, it is behaving exactly like there is a syntax error in the code except there isn't a syntax error, it is not running. – I have too many problems May 04 '13 at 00:49
  • Define "not running". – Thorbjørn Ravn Andersen May 04 '13 at 00:57

Open a terminal and execute the command 

$ ulimit -c unlimited

In this terminal, now launch your IDE Eclipse by command line

$ /Path/To/Eclipse/Eclipse.app/Contents/MacOS/eclipse

But this is not a solution for your error when your program is running.
