Answer 1

Specifying just a directory does not add the jar files in that directory to the classpath. You must add the jar file explicitly to your classpath like so --

E:\app\malisa\product\11.2.0\dbhome_1\jdbc\lib\ojdbc.jar

Or if you want to add multiple jar files, then you could use wildcards like this

E:\app\malisa\product\11.2.0\dbhome_1\jdbc\lib\*

Take a look at how to set classpath in Java 7 .

Answer 2

You could put the JAR file in the JRE/lib/ext directory. That means it will be on the classpath of every Java application. This is a little heavy handed though.
