I get the above error message when I try and change the default database in Jboss 4.0.0 to from hsqldb to postgresql. I went to the following resource which claimed that this problem had been fixed in Jboss 4:
but it has not, or is there something I am doing incorrectly?
I am currently running Jboss 4.0.0 and postgresql 7.4.5
Maybe it will be fixed in 4.0. I'm going to download 4.0.1RC1 this evening to have a look for myself. I'll report back.
