I am creating an application in java using glassfish server in netbeans. I’ve created connection pool and data source for sql query execution. I have created a sample jsp page to check the transection using connection pool which is as follows.
And as I run this file in browser I get this internal error.
“javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: “java.sql.SQLException: Error in allocating a connection. Cause: null””
Got the solution!! 🙂
The problem was. I didn’t set password for mysql. At the time setting up a new connection pool, providing password is mendatory. so I just added the password and now it is working. I hope if anybody else faces the problem then it would be helpful
