Unable to load the jdc driver

Question

Hi,
I am using mckoi, but I don't succed in loading the jdbc driver:
Class.forName("com.mckoi.JDBCDriver");This line throw a ClassNotFoundException. But:
cd $CLASSPATH; ls | grep mkjdbc.jar
mkjdbc.jar
So the jar file is in the CLASSPATH.
I try also:
import com.mckoi.JDBCDriver;But when it compile:
javac ConnectToServerDemo.java
ConnectToServerDemo.java:2: package com.mckoi does not exist
import com.mckoi.JDBCDriver;
Something strange:
java -cp mckoidb.jar com.mckoi.tools.JDBCQueryTool -u "admin_user" -p "aupass00"
It's work very well !
I don't understand and I have no idea.
It will be fine if someone can help me.

You should follow duffymo's advice and explicitly pass classpath on the command line.
However, classpath environment variable can work. It appears you have the directory in which the jar file resides in the classpath. Java won't find JARs automatically, you have to include the name of the JAR file explicitly.
E.g., if your jar is located in "/mydir" and your classpath environment variable contains an entry "/mydir" change it to "/mydir/mckoidb.jar", or better yet add that in addition to "/mydir" so classes are also found.
