Trying to install 'Merchant of Venice' on a Mandriva 2005 LE system.

I get the following error:
[don@localhost venice]$ /home/don/venice/venice
Error: JAVA_HOME environment variable is not set. This should be
set to the installation directory of java.

jre1.5.0 is installed in /usr/local/jre*.

I did;
[don@localhost venice]$ ln -s /usr/local/jre1.5.0_06/plugin/i386/ns7/libjavaplugin_oji.so

What am I doing wrong?

dlw

Try running this:

$ env PATH=$PATH:/usr/local/jre1.5.0_06/bin/
$ /home/don/venice/venice

If that works, post back and we can edit certain bash config files so that your java "bin" directory is in PATH w/o typing the above "env" command every time you want to run the program.

I'm guessing you are using bash so you need to add the following to your .bash_profile or .profile ?

export JAVA_HOME=/usr/local/jre*

replace the star with the version of the jre

$ env PATH=$PATH:/usr/local/jre1.5.0_06/bin/
$ /home/don/venice/venice

Did not work.
Nor did this;

export JAVA_HOME=/usr/local/jre1.5.0_06
export JAVA_HOME=/usr/local/jre1.5.0_06/bin

I even moved jre to /usr/java/jre*

Any ideas?

Did you do these one after another and retry i.e.

export JAVA_HOME....
run command
export JAVA_HOME....
run command

or did you do this
export JAVA_HOME
export JAVA_HOME
run command

You will also need you source you .bash_profile if thats where you are putting these lines.
source ~/.bash_profile

Finally you are
mixing syntax here evn PATH=$PATH... will not set the var you will need to run

export PATH=$PATH:/path/to/java/bin

Don't bother adding these lines to your profile yet, just run them like this in order right on the command line

$ export PATH=$PATH:/usr/local/jre1.5.0_06/bin
$ export JAVA_HOME=/usr/local/jre1.5.0_06
$ java -version

if you get a result like this :
java version "1.5.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)
Java HotSpot(TM) Server VM (build 1.5.0_02-b09, mixed mode)


You are on the right track and java is in your path .. next run the following

$ ls `echo $JAVA_HOME`

you will get a result like :
bin COPYRIGHT demo include jre lib LICENSE man README.html sample src.zip THIRDPARTYLICENSEREADME.txt

If this all works make sure mandriva does not have gcj installed as it may conflict with the version you installed from sun. Here is how to check.

$ rpm -qa '*gcj*'

If you get a result then you will next have to think about if you want to uninstall it which means you will break some rpm dependencies but thats for another post.

I mucked around with this program a while ago and from memory you don't install it you run it. Have a look at the readme instructions and it will tell you how to do this. It is via the command line. Look for macd or macg, something like that. If you can't figure it out post back and when I get home I'll have a look for you.

Your result from $ echo $JAVA_HOME is not right.
So you have to get it set correctly
I have the Software Development Kit...sdk version but here´s what I get
$ echo $JAVA_HOME /usr/java/j2sdk1.4.1_03/bin/
yours should return .......... /jre/bin/ and until it does it will not find java
I suspect adding a slash after bin might fix it or reinstall the jre folder as all the needed files may not be there

JK Installing and running seem to me to be the same A binary is placed in the /bin/ file and run ,installation does the same. A program cant be run until its in the $PATH

An alternative method for setting up java would be to copy the script below to /etc/profile.d, name it something like sun_jdk.sh and make it executable using "chmod +x". After that do "source /etc/profile" and java should be in your path (check by doing "echo $PATH") and that of other users on your system.
If the paths in the script are different from your java installation path, then adjust them accordingly.

So is this still not working? From looking at the output you pasted it looks like eveyrthing is correct?
