在OfBiz上安装PostgreSQL

Question

我试图在OFBiz上安装PostgreSQL，但是当我运行服务器时，当我访问http://server_address:8080/ecommerce/时会得到这个错误。

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). Rolling back transaction.org.ofbiz.entity.GenericEntityException: org.postgresql.Driver (org.postgresql.Driver) (org.postgresql.Driver (org.postgresql.Driver)) (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). Rolling back transaction.org.ofbiz.entity.GenericEntityException: org.postgresql.Driver (org.postgresql.Driver) (org.postgresql.Driver (org.postgresql.Driver))) (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).

不过，我不知道这是甚麽意思。我建立了一个名为ofbiz的基本数据库，其所有者是ofbiz用户。然后运行./ant load-demo，用演示数据填充数据库。我的操作系统是Debian /Linux 7.2。我还应该指出，我是PostgreSQL、OFBiz和Java的新手。很抱歉格式化，它就是这样来的。

你的问题还不清楚。我假设PostgreSQL驱动程序丢失了。默认情况下，By不附带PostgreSQL驱动程序，所以您需要下载它。转到ofbiz目录，在windows或./用于linux时运行以下命令。
