I attempted to setup OFBiz on PostgreSQL, but when I run the server, I get this error when I visit http://server_address:8080/ecommerce/:
org.ofbiz.widget.screen.ScreenRenderException: Error rendering screen [component://ecommerce/widget/CommonScreens.xml#main]: java.lang.IllegalArgumentException: Error running script at location [component://order/webapp/ordermgr/WEB-INF/actions/entry/catalog/Category.groovy]: org.ofbiz.entity.GenericEntityException: org.ofbiz.entity.transaction.GenericTransactionException: The current transaction is marked for rollback, not beginning a new transaction and aborting current operation; the rollbackOnly was caused by: Failure in findByCondition operation for entity [ProdCatalogCategory]: org.ofbiz.entity.GenericEntityException: org.postgresql.Driver (org.postgresql.Driver).

However, I have no idea what it means. I setup a basic database called ofbiz with the owner as the ofbiz user. Then ran ./ant load-demo to populate the database with the demo data. My operating system is Debian GNU/Linux 7.2. I should also note that I'm a newcomer to PostgreSQL, OFBiz, and Java. I'm sorry about formatting, this is how it came.
Your question is not clear. I am assuming that PostgreSQL driver are missing. By default ofbiz doesnt come with PostgreSQL drivers so you need to download it. Go to ofbiz directory and run the following command ant download-PG-JDBC in windows or ./ant download-PG-JDBC for linux .
