Java Thinking

I recently mapped a JPA entity to a view, and encountered this error while using hibernate to update the database schema: ORA-01702: a view is not appropriate here [SchemaUpdate.execute] could not complete schema update I was using the Oracle JDBC drivers 10.1.3.3 - luckily, the solution was to upgrade the drivers - when using 11.2.0.2.0 it works fine. Download ojdbc6.jar from here: http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html ojdbc6.jar (2,152,051 bytes) - Classes for use with JDK 1.6. It contains the JDBC driver classes except classes for NLS support in Oracle Object and Collection types.

I've just noticed that I've got no swap space! (Dell 1525 running Ubuntu 8.10). I first installed my laptop with Ubuntu 8.04, and later upgraded to 8.10. After the upgrade I noticed that hibernate no longer worked, and I think (from memory) I found an error message saying something about not enough swap space. I briefly thought about trying to find out how to add more swap (I already had a 4G partition defined, and I've only got 2G ram) but then I swiftly moved on to other more pressing issues. Well, just recently I fired up System Monitor to check on a process, and notice in the bottom right corner it said there was no swap space. Firing up 'top' confirmed this - my system had zero swap! I could see that I had a swap partition defined: paul@dell1525:~$ sudo blkid /dev/sda8: TYPE="swap" UUID="4bd53cb9-611c-4e57-a9df-4754d6bcdd65" But the corresponding entry in /etc/fstab had a different entry:. # /dev/sda8 UUID=e6eb6c47-599c-4612-ac8a-287279ee438...
