ClassNotFoundException after setting env variable

[Pat Peg]

Hey all,

I was trying to execute a little bit of code

        try {
            // Load the JDBC driver
            System.err.println("Step 1");
            String driverName = "oracle.jdbc.driver.OracleDriver";
            System.err.println("Step 2");
            Class.forName(driverName).newInstance();
            System.err.println("Step 3");

but it fails right there at the Class.forName. I read that I needed to set the CLASSPATH so I did, both for the system and for me the user...
classpath = .;C:\Program Files\Java\jre1.6.0_07\lib\ext\QTJava.zip;C:\Program Files\Java\jre6\lib\ext\QTJava.zip;C:\jars\classes12.jar

but I am still getting this exception. What else should I do?

[Pat Peg]

So I ran this from the command line

java oracle.jbdc.driver.OracleDriver

and I got the classNotFoundException again so I am guessing that I don't have the variable set correctly but it appears to be. What else could I do. I am a windows machine and set the variable by going to properties of my computer and editing the classpath variable.

I have restarted (a couple of times)...

At the command prompt, type "SET". A bunch of environment variables will be shown. Please tell us what the CLASSPATH is there.

[Pat Peg]

CLASSPATH=.;C:\jars\classes12.jar;C:\Program Files\Java\jre1.6.0_07\lib\ext\QTJava.zip;C:\Program Files\Java\jre6\lib\ext\QTJava.zip

You have classes12.jar in C:\jars, right ?

I was trying to execute a little bit of code

How did you execute it ?

[Pat Peg]

classes12 in the jar file? Yes. It is about 1500kb in size and is there.

Tried running it from jdeveloper-I haven't used jdeveloper in years so it could be that there is something to set up that I don't know about. I am trying to research that now.

Now that's a different problem. JDeveloper is probably not using your environment variable. I think you have to configure the libraries used by your program in JDeveloper. Something like this ?

Cool-thank you. I am reading it now.
