Hi people! I'm going to start doing lots of Java on my Linux machine! I've downloaded the linux JDK, JRE and J2EE, and installed them fine on my system, but there's still a couple of issues: 1) I can't execute the programs directly, ie. to run 'javac' i have to type './javac' instead of plain old 'javac'. Is there some way of rectifying this? 2) I don't know which system file to declare my java vars in (ie. JAVA_HOME etc..) (I'm on Redhat 7.1) Maybe (1) will be sorted as soon as we rectify (2) - i just don't know... One last thing, i installed all of the above packages as root, is this a good idea, or should i create a new user for all of the Java things to run under? Thanks for your help Robin
on redhat 7.1 you can put your java variables in ~/.bash_profile you need to add . to your classpath so you can execute programs in the current working directory. so, your classpath in the ~/.bash_profile file should have something like this: CLASSPATH=$CLASSPATH:.:/path/to/java/programs: [ January 16, 2003: Message edited by: Greg Harris ]
let your PATH variable in /etc/profile point to bin directory of your jdk installation. say /usr/local/jdk/bin. setting CLASSPATH will solve your class file lookup problem. for the last thing. Even I am not sure about how good the idea is to set it as root. can anyone throw some light on this part?
