Studio 5 suddenly is not aware of the Oracle jdbc driver I copied into ext

Hi.

I installed Sun One Studion 5 and one of the first things I did was to copy the Oracle jdbc driver to lib\ext, in order to test how the IDE 'understood' the Oracle schema. Everything was fine, including re-compiling and running jdbc programs (I copied from my jDev IDE). But now, a day later, suddenly the IDE rejects all theimport oracle.... statements, informing me that these classes don't exist. Likewise the compiler will not compile. But... the Oracle jar file is still there, and I even copied over it just in case it was damaged.. to no avail.

So...

1. Why does it not work now.

2. Why did it work in the first place.

thanks
