When trying to run the netbeans shell installer, it gives me an error.

```
./netbeans-7.0.1-m1-php-linux.sh
Configuring the installer...
Searching for JVM on the system...
Extracting installation data...
Running the installer wizard...
No protocol specified

```

This error came after I did `export DISPLAY=:0.0` because that was an error too. Any ideas?
This is on debian by the way
