My laptop doesn’t have a lot of memory. Only 384Mb. This means that I can’t run JDeveloper and Oracle RDBMS at the same time. So i installed postgresql (on windows 2000). With this setup i tried to follow some of the examples published on OTN. It seems that business components and postgresql don’t really work well together. Some parse errors, and I can’t create tables from the entity objects. The string attributes are translated to varchar2 columns.
BTW, you really need memory, I’m using 590Mb right now, running postgresql, mozilla, and jdeveloper. No application server running…
