JVM Creation Failed

Troubleshooting General Help
1

Hello!

I’ve just installed the JMonkeyPlatform. When I try to start it I get this error: “JVM Creation Failed”. Only one time the software started and then ended because I needed NetBeans.

How can I solve the problem? Why the JVM Creation fails?

I work with Windows XP.

Did you already install the jdk in your machine? You don't need install netbeans to install jMPlataform.

I installed this: http://hub.jmonkeyengine.org/downloads/?did=1

And then this: https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=jdk-6u23-oth-JPR@CDS-CDS_Developer



It’s ok?

Yes. Can you upload the error here? Perhaps uninstalling the jdk properly and reinstalling should works.

5

Yeah, you should be installing the jdk first (so in this case reinstall jmp)

I’ve already tried. Anyway I will try again tomorrow.

What should I upload? A screenshot?

Yes. But this problem already happened to me. And this just was solved when i uninstalled "properly" the jdk and reinstalled. When i said "properly" isn't just to remove the jdk installation, but to remove all jdk registers also. I removed all jdk registers in my machine executing the command line "regedit", then I removed the registers "one by one" searching for the word "java". Sometimes when you uninstall the jdk, it isn't removed properly, just you see still there is the "C:Program FilesJavajdk1.6.0_23" folder.

I reinstalled jmp. First I get an error saying that jdk wasn’t found. Then a critical error that blocked the system… And at the end I installed it successfully. But the error always appear… This is a screenshot.





I will try to uninstall also the jdk…

Nothing works… I uninstalled jmp and jdk. I cleaned the registers with the Advanced SystemCare Tool and then checked with the regedit command. Then I rebooted, installed the jdk, rebooted, installed the jmp, rebooted. But I always get the same error. I don’t believe the problem is the installation. Maybe I used the wrong software version. I used the ones I linked before.

Hmm! This is a memory problem, so you have to modify the jMonkeyPlataform’s startup settings to allocate more memory for it. It will stop running when it reached the limit of memory. Open the " C: Program Files jmonkeyplatform etc jmonkeyplataform.conf" file to modify the “-J-Xms24m” and “-J-Xmx512m” commands. If your machine is between 256 mb ram and 1gb ram then set it to “-Xms64m -Xmx1024m”. If it’s 2 gb or more then set it to “-Xms64m -Xmx1400” to get maximum performance. Hope this works ;).

Hi! I found the same solution on the NetBeans forum. It seems to work! My machine is 1gb RAM. I set the config to: -J-Xms24m -J-Xmx256m… Next time I will try with the values you said.

Thank you very much again!

My solution is to make “perm” option a comment as follows :

default_options="–branding jmonkeyplatform -J-Xms64m -J-Xmx1024m

#-J-XX:PermSize=256m

in the jmonkeyplatform.conf file.

Anyway, your replies were very helpful, and Thank you so much…
