unable to open display localhost:0.0 in VMware RedHat linux machine

178210Jan 5 2007 — edited Feb 28 2007
I have been trying to Install Oracle 10g RAC in VMware linux virtual machine.

my virtual machines are running properly and I am able to use RSH & SSH.

when I run runInstaller it is not comming up due to DISPLAY environmental variable setup.

I have set the varable as follows
DISPLAY=localhost:0.0; export DISPLAY

then if i execute xhost + it gives the following error
"xhost: unable to open display localhost:0.0"

I have tried with ipaddress instead of localhost. Eventhen it is giving the same error

What is the problem? How I can solve the issue?

I clicked on that link and the application downloaded and ran just fine. (At least it would have if I hadn't declined to allow it to run unrestricted on my system.) I didn't clear my cache or disable my firewall or any of that BS that help desks like to tell you, either. But I do have Java 7 installed on my system, not Java 6.

Perhaps you are connecting through some kind of proxy server which is rejecting some of the JNLP's requests and returning HTML saying so?

- In JNLP, do something mentioned below:
<j2se version="1.6.10+" href="http://java.sun.com/products/autodl/j2se"
java-vm-args="-Djava.net.preferIPv4Stack=true"/>

This may help you....

So, I had exactly the same issue as above for a long time now, the helpdesk tried their best and followed up but this piece of code did the trick.

I opened the JNLP file in wordpad and replaced everything that came after "<J2se version=" with what you gave above, so that it looked like this:

j2se version="1.6.10+" href="http://java.sun.com/products/autodl/j2se"
java-vm-args="-Djava.net.preferIPv4Stack=true"/

then I opened the file in the Java Web Launcher
and voila, the darn thing worked.

Hi, I've missed three weeks of classes because of the same error listed above.  Everything was fine and Blackboard Collaborate Elluminate worked almost effortlessly for 5 or 6 weeks.  Suddenly I tried to log in for a live lecture and this error occurred.  Other students were having trouble and still are.  Tech support at the school couldn't fix it, so they referred me to Blackboard Collaborate tech support (level 2).  They haven't been able to fix it either.  They recommended the same steps listed at the top of this email.  I executed all of them but still receive the same error.  Additionally, at one point, I was unable to install Java.  Funny things seem to happen when I get on the line with tech support to solve this problem, although funny things don't happen during the other work I do on this computer.  Technical language, I know.  :-)

In an effort to pass the class, I am doing research on own to try to fix this and get into the lectures.

I am getting the same error listed above but am not a developer and don't understand how to get to JNLP to enter the fix listed above (if someone has a hint, I'd love to try that fix).

Any help would be very much appreciated. 

System Info

OS:  Windows 8

Browsers:  IE (threw this one out), Chrome, Firefox, Safari (tested in all four)

Sample of Recorded lectures I'm trying to access (missed live ones):

Here are steps taken so far:

1. Clear Java Installed Apps and Applets (Control Panel - Java 32-bit - SEttings - Delete files - Installed apps and applets - ok - ok - ok)

2.  Delete all files in Downloads folder (from all browsers)

3.  Allow Java in Windows firewall (Start screen - hold down Windows key and W - Search for "firewall" - Navigate to Java program name - click all boxes and save)

4.  Ran CCleaner to remove all temporary internet files, cookies, etc. that could be interfering

5.  When nothing else worked, uninstalled and reinstalled Java twice (on the second time, it took over a dozen tries to reinstall Java - suddenly it just worked) and both times I deleted the Sun folder (C:/Users/Me/appdata/LocalLow/Sun) at the direction of tech support

6.  Removed old registry entries both times using CCleaner

7.  Rebooted (something done all along the way to see if it helped)

8.  Tried to access live classes and recordings from multiple lectures through Blackboard Collaborate Elluminate and received the same error (details included below)

9.  Tried to access Blackboard Collaborate Elluminate with Windows firewall on, then Windows firewall off, then ZoneAlarm Extreme firewall on, then ZoneAlarm Extreme firewall off (and entire associated software package); when on, ZoneAlarm gives "super" trusted status to all parts of Java listed and gives green checkmarks for all parts of Java listed and all levels of security

10.  End results so far:  receiving same error - nothing works

Here's the error followed by a copy of all text from the details section.

ERROR INFO BEGIN (my note on beginning of actual error language)
