How to add ojdbc.jar to my classpath?

I have written a simple jdbc application to insert a record in database.

Before compiling, i need to add ojdbc.jar to my classpath.

How to do that?

On doing this, C:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar, it shows an error dialgue box stating,

Failed to load Main-Class manifest attribute from C:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar

Place it under "lib" folder in WEB-INF folder (ojdbc14) if there is any other jar files also recompile it

Few things you should mention here.
1. How do you compile, using a build script or just from the direct "javac" command?
2. What kind of application is this, web/desktop etc...?
