Binary package hint: netbeans5.5

How do you start NetBeans? Is Java already running? (IDE launcher is shell script which starts java process.)

[Marek Slama (mslama-email)]

If you see splash screen it looks like Java process is already started. Then use jps from JDK to get PID of NetBeans and then jstack to get thread dump. Then please attach it here. I recommend to use JDK 6 as jstack from JDK 6 is able to dump thread dump even from running process. You can set JDK for IDE either on command line using --jdkhome <Path to JDK> or by modifying /etc/netbeans5.5/netbeans.conf: Change line starting with "netbeans_jdkhome=". Of course lines starting with # are comments.

SO i found out what was wrong , java 6 was installed but the system was using another jvm wich comes with ubuntu i remove it and now it works fine .Thanks

[Marek Slama (mslama-email)]

It depends what java is set as default alternative. You can either set Sun Java as default (either 6 or 5) or modify /etc/netbeans5.5/netbeans.conf: Add line
netbeans_jdkhome="/usr/lib/jvm/java-6-sun"
to point to Sun JDK 6 or
netbeans_jdkhome="/usr/lib/jvm/java-1.5.0-sun"
to point to Sun JDK 5 depending what JDK version is installed.
I added code to postinstall step to patch newly created netbeans.conf (if there si already one in /etc/netbeans5.5 user will have to modify it manualy or run purge on netbeans5.5 package first.
