hello, first , when i do the java -version and javac -version i get the version ,
also
echo $JAVA_HOME points to /usr/lib/java
i installed java jdk from the slackbuilds.
the problem comes when trying to compile a java servlet in netbeans,
i have tomcat setup , everything, the whole package , this is not me missing some .jar file in the lib folder in tomcat.

i even export it the tools.jar file to tomcat , but still when i compile my programs, netbeans says

/home/mdj/apps/imagej/build.xml:9: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK
BUILD FAILED (total time: 0 seconds)

when i javac some file.java , it compiles fine.
also i edited /etc/profile and set it to point to the java jdk
/usr/lib/java , and also tried with /usr/lib/java/bin
nothing , slackware ignores any changes to /etc/profile,
i almost fell of my chair when slackware ignored any changes made to profile, i even logged out and restarted, and nothing, no change

so what do i do to affect that /etc/profile ?
i am root when i do that, do i become megaroot , ultraroot or what

How are you starting X? startx or runlevel 4?

I've encountered this problem and (after much trying) the only solution I found was to fall back to an earlier version of netbeans. Netbeans 6.5.1 doesn't seem to suffer from this problem.

EDIT: Solution found, thankfully, here.

i use startx
using the latest netbeans 6.9

after this , i think i am going to fall back to using another linux distro or windows.

the rightest levitra decidion!!!

Did you still have the JRE package installed?

You should uninstall the JRE when you install the JDK.

Who are you threatening by saying this? You can keep comments like this to yourself when you are trying to learn how to get something accomplished. You are asking for help for free. Go pay for support, if you expect that level of assistance.

1) when installing the jdk, you must unistall the jre (*first*)
2) to get the proper login environment variables, sometimes it helps to logout and back in again. Otherwise the bash env settings for the jdk are in /etc/profile.d/jdk.sh You can source that file to let them get set for your current shell
3) not sure why any of your actions as root were needed. As your user, ~/.bashrc and ~/.bash_profile are all that you need to hack on. They are different files, that have different invocation. If you are not familiar, then I refer you to the bash(1) man page, in the INVOCATION section.


Take care,
