I am ivestigating the use of CachedRowSet from Sun. I have wriiten a small program that just reads a table and then prints each row on System.out. I use the import statements: import java.sql.*; import sun.jdbc.rowset.*; This all works fine in IDEA. I can see all the methods of the CachedRowSet class. However when I try to run the application using Shift+F10 I get a NullPointerException when reference to CachedRowSet is encountered. The Classpath is set in the project as: C:Oracle9ij2eehomelib owset.jar This must be OK as I can see the methods of the CachedRowSet class. So what am I missing? Nige    More>>

I am ivestigating the use of CachedRowSet from Sun. I have wriiten a small program that just reads a table and then prints each row on System.out.
I use the import statements: 

			

			import java.sql.*;
			

			import sun.jdbc.rowset.*;

This all works fine in IDEA. I can see all the methods of the 
CachedRowSet
class.

However when I try to run the application using Shift+F10 I get a 
NullPointerException
when reference to 
CachedRowSet
is encountered.

The Classpath is set in the project as: 
			C:Oracle9ij2eehomelib
			

			owset.jar

This must be OK as I can see the methods of the 
CachedRowSet
class.

So what am I missing?

Hi Nigel



In general, the NullPointerException means that the class was found properly by the class loader, it just isn't initialized or was set to null.



So I think your classpath is ok and there is another issue. We can only know more if you can provide some more info about the source.



Hope that helps,


Matan
