edit your `/etc/profile' file and set the PATH for your java home and java binary directory in that add something like this: export JRE_HOME=/usr/java/jre1.5.0_05 export PATH=$PATH:$JRE_HOME/bin edit it for your self <div>On 12/6/05, Alfred Vahau <<a href="mailto:Alf.Vahau@upng.ac.pg">Alf.Vahau@upng.ac.pg</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I have installed the j2sdk1.4.2_10 Java binary on my Ubuntu system (Warty) and made a symbolic to the java and javac commands in /usr/bin/java and /usr/bin/javac. /usr/bin is on the PATH environment. Where I issue the which java command, it returns a blank line. When I issue whereis java it returns a positive output: java: /usr/bin/java I conclude that the output of the which command is an acknowledgement of the path being correct. For instance, I can issue which perl and get the result /usr/bin/perl so the perl command is on the system path. The java symbolic links are soft links and created thus ln -s /usr/local/bin/j2sk1/4/2_10/bin/java /usr/bin/java ln -s /usr/local/bin/j2sk1/4/2_10/bin/java /usr/bin/javac The java binary file (with extension bin) was unpacked in the /usr/local/bin directory. How can I get the system to recognize that java and javac are on the environment path? I have tried rebooting (I didn't think this was necessary but tried anyway and it didn't make a difference.) For noting the execution of the java command is successful when I am in the directory containing the command and issuing a command for an example like so: ./java -jar SampleTree.jar and I get a window with the demonstrated output. Thanks in advance for any pointers.
