Hello There,



I am using RedHat6.2. I have written a java program and it compiles fine. But when i try to run it , it gives the following Exception


classNotFoundException: oracle/jdbc/driver/OracleDriver



when my OracleDriver is in the classpath.



I tried using the -cp option, i.e.,


java -cp $CLASSPATH InsertRows



Now i get the following error



java.lang.NoClassDefFoundError: /:/usr/java/jdk1/3/1/lib:/usr/java/extlib/classes111/zip



If u could notice the folder name jdk1.3.1 is taken as jdk1/3/1, similarly classes111.zip is taken as classes111/zip. Why is this happening. I have used redhat before and not faced problems like this, after i reinstalled I am getting these exception.


Does anyone have idea what the reason could be, I could'nt find a answer in any other forums, and already wasted two days digging into it. Help will be very much appreciated.



Thanks in advance

My guess is that you've got an errant space in your CLASSPATH environment variable. That could explain not finding the Oracle jar and also interpreting part of the "-cp" argument as a classname instead of part of the classpath.
