我试图在PostgreSQL上设置OFBiz，但是当我运行服务器时，我在访问http://server_address:8080/ecommerce/时收到此错误：
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).

但是，我不知道这意味着什么。我设置了一个名为ofbiz的基本数据库，其所有者为ofbiz用户。然后运行./ant load-demo以使用演示数据填充数据库。我的操作系统是Debian GNU / Linux 7.2。我还应该注意到，我是PostgreSQL，OFBiz和Java的新手。我很抱歉格式化，这就是它的来源。

你的问题不明确。我假设PostgreSQL驱动程序丢失了。默认情况下，ofbiz并不附带PostgreSQL驱动程序，因此您需要下载它。转到ofbiz目录并运行以下命令 ant下载-windows中的PG-JDBC或./ant下载-PG-JDBC for linux。
