Hi, I have looked into documentation, in data-sources.xml configuration I have made changes as shown in "How to setup data source". but after that it has been suggested to copy the driver into orion directory. If you have any idea which driver and where it is located please let meknow. another Qestion is where should i install cloudscape? just like HSql under orion folder or somewhere else (like i have installed under /usr/local in my linux box) __________________________________________________ Do You Yahoo!?
