Hello new to Linux here,my first post here I download the jre and installed it was a bin file so it chmod 755 and ran it. Then I tried to install the JDK which was a jdk-6u24-nb-6_9_1-linux-ml.sh when I do chmod on the file and run it, I get:

Configuring the installer ...
Searching for JVM on the system ...
preparing bundled JVM ...
Extracting installation data ...
Running the installer wizard ...
No protocol specified

the problem is obviously the last line that stops the installation, I know i can download the .bin file and it will be easier but I wont learn anything that way, I might come accros this error in a similar environment any help please.

The problem is that the installer is trying to use X Windows (for the GUI), and it can't.

Q: You're installing from a GUI desktop, correct?

Q: You're running in the GUI as a normal user (and not "root"), correct?

Suggestion:
Try this:
1. Start a command prompt
2. Type "cd ~/Downloads" ("cd" to whatever directory your .sh files is in)
3. Type "xhost +" (this will temporarily leave your X server unrestricted)
4. Try running "./jdk-6u24-nb-6_9_1-linux-ml.sh" again

I had the same problem with jdk-7u9-nb-7_2_1-linux-i586-ml.sh and it solved. Thank you.
