problem in set the $PATH and $CLASSPATH in my .bashrc

Hi, I'm trying to communicate my j2eesdk -not openjdk- with mysql through mysql-connector-java, so I have to setup an specific data in my $PATH and $CLASSPATH vars in .bashrc, here it is:

Code:

#j2ee
export PATH=/niit/j2eesas/jdk/bin:$PATH
JAVA_HOME="/niit/j2eesas/"
export JAVA_HOME
CLASSPATH=/niit/j2eesas/lib/j2ee.jar:/niit/j2eesas/jdk/jre/lib/ext/mysql-connector-java-5.1.7-bin.jar
export CLASSPATH

after reboot my system, checking these vars, I've got this:

Code:

tamayo@gxa16b14:~$ $CLASSPATH
bash: /niit/j2eesas/lib/j2ee.jar:/niit/j2eesas/jdk/jre/lib/ext/mysql-connector-java-5.1.7-bin.jar: file or directory doesn't exist

I know that the file mysql-connector-java-5.1.7-bin.jar is in the correct directory -the directory that is written in the CLASSPATH var; but I don't understand why it didn't find, and obviously testing this config from within a JAVA program I got the same: ClassDefNotFound

My question is:
what am I doing wrong in setting my $CLASSPATH var? I have to point to mysql-connec-java.jar to communicate mysql and java and the correct setup of the CLASSPATH is very important. any suggestions are welcome

What is niit? Is that your user? If so, you would have to use /home/niit/etc instead.

Also, don't forget the $ sign if you export a variable that is not defined in the same statement.

Whoops! You forgot 'echo' before your var.

(To print out a var, use 'echo $VAR', not just '$VAR'.)

you DO NOT put the file name " mysql-connector-java-5.1.7-bin.jar" in the path
You put the FOLDER it is in ,in the system path .

Not true, that does not work for jar files.

jar files aren't really folders, they are archives
if Bash supported extracting files from archives on the fly without explicit decompressing, that would be a nice feat, but as you can see, it doesn't
