Hi !

I have 3 simple queries

1. I've installed JDK on my RH7.3 . Now I'd like to uninstall it, how do I do that ?? I checked the Control Panel,etc...couldn't find it. Also browsed the book briefly.

(I installed JDK from a .bin file)

2. When I go to the bin directory of the installed JDK, and type java -version, I get 'file not found.....' .

From my knowledge of windows, although you need to set the PATH variable, but if you go the JDK bin directory and do 'java', it does work. Why not in RH Linux too ?

So, how can I start compiling Java programs ?

3. NTFS is not supported on my RH7.3 install. Still , is there any way I can read the NTFS partitions ?


Thanks very much.

you should look at my guide (it's in my sig below)

usually for uninstalling programs, it is..

for rpms - rpm -e filename
or for source files - make uninstall filename

as for ntfs, there is support but you need to download a rpm for it.

1- If you installed it from a .bin file, probably you cannot uninstall it from rpm.

Go into JDK directory. Search for an "uninstall" script or whatever. If it doesn't exist, it should suffice with deleting the whole directory containing jdk.

2- You can't run java --whatever because the "actual" directory is not set in the PATH for security.
If you go the JDK bin directory as you said, you should exec like:

# ./java

That way you are giving the actual directory as PATH.

Else, you can add tha actual directory (" . ") to /etc/profile:

PATH= $PATH:.
export PATH
