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. Alfred, </body> </html>
