accessing java class that uses jdbc

Migrateduser

Hi everyone,

I created a report using a java class using an oracle connection. But when I previewed the report in Eclipse 3.4 All-In-One, it always giving me an error no class fount oracle/jdbc/driver/OracleDriver and the class files must be in C:Eclipsepluginsorg.eclipse.birt.report.viewer_2.3.0.v20080606birtWEB-INFclasses.
What I did was extract the classes12.jar and placed the java class in: inC:Eclipsepluginsorg.eclipse.birt.report.viewer_2.3.0.v20080606birtWEB-INFclasses and it worked fine.

But I would like to know if where I could place the classes12.jar in Eclipse so that I would not exact the jar file? And, do I really need to place the classes I made in C:Eclipsepluginsorg.eclipse.birt.report.viewer_2.3.0.v20080606birtWEB-INFclasses?

Thanks in advance
