The system is x86_64 openSuSE v10.2.
Previously, it contained jre v1.4.2, and PATH contained the string .

but seems to ignore completely the question of changing existing directories. How to go about this?
The first thing is that Java is a bit special about it handles these things, the system path is usually irrelevant to java. JAVA_HOME is important... as are a few other variables...
So far, I have been using full pathname to call java 1.6.0 to start java applications (because PATH isn't correct for this version, as I said). I would, however, like to make the needed correction, if for no other reason than to shorten the command line in the scripts that call these apps. But I take your point -- the other variables are important.
The jre that I installed was indeed installed through YaST from an rpm package:
, because I find it in YaST's Software Management tool. I do not find the jdk; what is the method I need to use for removing it properly, after which I will try to find the appropriate rpm package? Although I removed the jre v1.4.2 package using YaST, I now find the following two installed packages in Software Management:
jre-1_4_2-gci-compat jre-1_4_2-gci-compat.32bit
I don't recognize these; shall I remove them, since there is no corresponding jre?
Look at the following
/etc/java/java.conf /etc/profile.d/alljava.sh
to get an idea of what is happening.
I would recommend using the SuSE rpms (particularly on x64 systems) as things are a bit non standard (in a rather elegant manner).
Firstly with the SuSE Java installation I would have expected a symbolic link from /usr/bin/java to /etc/alternatives/java for later configurations (this is a link into the the java installation tree. This rather hides some of the messy version numbering bits so is largely version tolerant...)... or some such..
The other two are hangovers from 1.4.2 which was only available in a 32bit form...
Then I gather that I may remove them, as seemed reasonable.
I do not remember seeing any java stuff in the system path in the past on SuSE but I tend to work with Eclipse so this usually well hidden... Java is supposed to be OS agnostic so it carrys around it own environment. ...
But at the moment, there are three questions on the practical level, of which two remain problems: 1) The jre was installed where it is by rpm without asking me; it is easy to remove if I choose to do so; this is not a problem. 2) The jdk was installed (foolishly, without thinking) in my home directory, and I really want to remove, and to do so in such a way as not to make more trouble for myself. The Software Management tool is of no help for this. How should I go about removing it, so that I can reinstall from an rpm package? 3) It is possible that the jdk installed by rpm will straighten out the PATH question automatically. I would still like to know how one can revise or remove a directory (i.e. the string between two colons) in the PATH variable.
