Error message when I am running Netbeans 7.

Asked By 10 points N/A Posted on -

Hi all.

This morning, I’ve found an error message when I am running Netbeans 7 in my Windows PC and unable to find the past splash display. So I need to try this command line.

netbeans.exe -J-Xmx512m

Guys, can you give me suggestion or possible solution for this? Any suggestions would be greatly appreciated.

 1. First go to the directory where netbeans is installed ( C:/program files/NetBeans 7.0)..

 2. Then open the net beans folder..

  3. Go to the “etc” folder (C:/program files/NetBeans 7.0/etc)…

Working with NetBeans on a Windows XP/Vista this is a common error. It’s solution is simple. Just add an extra option in the configuration file and see your problem has gone.

To fix this error go to NetBeans configuration file under: C:Program FilesNetBeansetc
Open "netbeans.conf" into Notepad.

Orginal configuration row is:

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true"

Now simply add this extra parameter to the above row:


MaxPermSize is connected to the Permanent Generation. In Java, Permanent Generation has the Class Object. Netbenas is developed in Java and at startup generates Class dynamically. So, when the default size of Permanent Generation becomes too small that time this error appears. To solve this issue just adjust the size of the MaxPermSize.

After adding the extra parameter finally the row will be looks like:

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=128m -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true"

Now restart the NetBeans.
