Glassfish + Postgres無法ping通連接池

Question

我嘗試使用Glassfish 3.1和Postgres製作Web應用程序的登錄頁面。我有本地數據庫（localhost：5432）。這是我的連接池：

Pool Name:pacjentauth 
Resource Type:javax.sql.DataSource 
Datasource Classname:org.postgresql.ds.PGSimpleDataSource 
Driver Classname: [nothing here] 

portNumber，ServerName，用戶名和密碼都可以。 這是我得到的錯誤：

任何想法什麼可能是錯的？如果沒有足夠的信息，請告訴我你需要什麼。

Answer 1

好吧，這一切都是關於罐子。我將這些文件複製：

postgresql-9.2-1002.jdbc4 
postgresql-9.2-1002.jdbc3 

到C:\Users\epcs\GlassFish_Server\glassfish\domains\epacjent\lib最後和它的工作原理。

Answer 2

您是否試圖將Postgres JDBC驅動程序jar放入您的GlassFish lib目錄中？使用MySQL，我們必須下載一個MySQL JDBC驅動程序並將該jar文件複製到/opt/glassfishv3/glassfish/lib。
