If I double click on the executable or click on the icon from the Start menu, the JBuilder splash screen shows for a second or less, then the process goes away. I'm running Windows XP with all relevant service packs and patches applied. There is no error logged in the Event Log, no error is shown when the process goes away. However, if I drop a jpx file on the executable, it starts up and opens that project just fine. Does anyone have any ideas about what's messed up on my machine? -Rick Back to top Lori M Olson [TeamB] Guest Posted: Mon Nov 14, 2005 9:30 pm    Post subject: Re: JBuilder doesn't start Rick Langel wrote: Quote: This problem originally started with JBuilder 2005, I've since uninstalled that version and installed 2006 and it's still happening.

You could try to remove your ~/.jbuilder2006 and ~/.primetime2006 directories (or parts thereof), and then restart JBuilder. Given the symptoms you described, I would start by just removing the ~/.primetime2006/user.properties. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.

Cool, thanks, I didn't know you could do that. Here's what it reported: Error occurred during initialization of VM Could not reserve enough space for object heap Unable to create JVM. I found this one Borland Answers: http://support.borland.com/entry.jspa?externalID=3033&categoryID=54 Setting the vmmemmax property lower fixed the problem, thanks for your help. But it doesn't really answer the question about why it happened in the first place? Did I install some app which changed my Java environment somehow?

You may have caused it by adding more memory to your system? I believe that 75% problem first appeared with machines that had over 1 GB of memory installed. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.

Oh well, guess I need to just chalk it up to the Twilight Zone. -Rick Back to top Borland public Guest Posted: Fri Dec 30, 2005 12:54 pm    Post subject: Re: JBuilder doesn't start "Rick Langel" <langelrj (AT) hotmail (DOT) com> wrote Quote: Lori M Olson [TeamB] wrote: You may have caused it by adding more memory to your system?

Oh well, guess I need to just chalk it up to the Twilight Zone. I had the same problem. Would be kinda nice if the JBuilderw.exe would report the error rather than just disappearing. My question though: what is the best value for vmmemmax? I tried 50% and got the same error. I have settled on 25%; this is pure trial-and-error. I have 3.0GB RAM installed.

Tim The "best" value varies according to the machine involved, the amount of memory installed, and the number of other applications that are running at the same time. It is really a "per user" setting, and it is really trial and error to find the "right" setting for yourself. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.

Well, we can do a bit better by reading config_readme.html. This states: "Set maximum Java heap size (you can specify by size or a percentage of the available physical memory, percentage allocation ? 1Gb) " So it appears that the result of the percentage value must be no more than 1GB. Confirmed here: I have 3GB and if I set it to 34%, JBuilder will not start. It also appears that JBuilder install will fail on any machine with more than 1.33 GB physical RAM. If so, this seems careless. Why can't the installer detect and amend the figure accordingly?
