[Navin Pathuru]

When running ServletDemo1, it seems to be looking for com.jrefinery.ui.Drawable and it is not there. Can you tell me where i can find it?

Thank you,
Navin Pathuru

[David Gilbert]

Unless I've messed up the packaging, it should be in the jcommon-0.7.0.jar file.

Regards,

DG.

[Navin Pathuru]

David,

Sorry for the confusion. You are right. I forgot to include the JCommon files so i got the above errors. They are now resolved and everything works fine.

Thank you,
Navin Pathuru
