I installed Netbeans 7.0.1, and I've made sure to install all the JDKs and JREs I could find. It installed without errors. I also saw this question and made sure I followed all the instructions there as well.
I never got any error messages of any kind. So far as I know, it installed okay.
However, when I try to run Netbeans, I get no response. If I run it from the command line, after about 30 seconds, the prompt just comes back. There's no error message of any kind to let me know what's wrong.
$ /bin/sh "/home/dave/netbeans-7.0.1/bin/netbeans"
$
What's the issue, and how do I get Netbeans to run?
New command line output as a result of following instructions offered in an answer:
$ sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
Press enter to keep the current choice[*], or type selection number: 2
update-alternatives: using /usr/lib/jvm/java-6-sun/jre/bin/java to provide /usr/bin/java (java) in manual mode.
$ /bin/sh "/home/dave/netbeans-7.0.1/bin/netbeans"

ok, dave, since you posted as a search term ubuntu 11.10.. ill assume you are running Ubuntu 11.10.. :D
I am running also the same version, fully updated today, the version im running is 64-bits, but that shouldn't make the difference.
This is what i did to install netbeans 7.0.1 on my box:
1) Download Netbeans from their website: http://netbeans.org/downloads/index.html choose freely the version you need. (dont try to install it yet)
2) Install from the repos the openjdk 6:
sudo apt-get install openjdk-6-jdk
3) run the netbeans installer you downloaded previously:
or if you want to make it easier for the eye, "cd" to the place where you saved the download, (usually the Downloads folder) and :
The installer should launch and check for the JDK, it also shouldn't say anything about the JDK (it displays a warning message only if it doesn't finds it).
Now you should be able to follow the installer without any problems.
I just downloaded and installed the full version without issues following this steps:
I hope this works for you...
This is the reference where i found the solution that worked for me: http://ubuntuforums.org/showthread.php?t=1873487&page=2
[Edit] Just in case, check the download checksum
It should return that it sais on the netbeans.org download page says, in my case thisis the output for the 204mb download:
