Hi,

I've installed OpenFOAM 1.4.1 on Ubuntu 8.04. Tutorials work OK but I have troubles when trying to open FoamX. When I type "FoamX" at the terminal, I get the following message (headers removed):

HostBrowser running.....

I've checked and the files it is looking for are correct and in the correct directories (no case sensitivity issues).

Can anyone help me? I'm a newbie when it comes to Linux I'm afraid - just starting out.

Hi Oli,
The problem has been discussed already on other threads. See this answer for instance:
xlib.lock

My FoamX don't run. The message appear to me:
Cannot find JDK at /home/delio/OpenFOAM/linux64/j2sdk1.4.2_05. Please set JAVA_PATH to the
JDK installation directory.

I don't know where is it, and I don' know how to configurate it.
I need a help about this
Tanks

What does the following command tell you:

ls -la /home/delio/OpenFOAM/linux64/

Hi all!

I am new Linux+OpenFoam user.

I have met the same problem:

~/OpenFOAM/OpenFOAM-1.4.1/bin> FoamX
Cannot find JDK at /usr/java/jdk1.4. Please set JAVA_PATH to the
JDK installation directory.


Iori@linux:/usr/java> ls -la
total 12
drwxr-xr-x 3 root root 4096 Mar 30 23:47 .
drwxr-xr-x 13 root root 4096 Mar 30 21:37 ..
drwxrwxr-x 9 root root 4096 Mar 30 23:47 j2sdk1.4.2_17


How I can set this JAVA_PATH?

You look at the download page

http://www.opencfd.co.uk/openfoam/linux.html#linux

and right down the bottom it tells you which file you have to modify.

Regards.
