Обсуждение: Cannot create PoolableConnectionFactory
Hi, I am using PostgreSQL with Spring, Hibernate on my web application. I came across such an exception when my application attempts to query the database. It is strange that it didnt happen when the application creates and populates databases; but when it performs "selects" operations. The exception message is: ------------------------------------------------------------------------------------- Exception invoking listener method onLogin of component Home: Failure invoking listener method 'public java.lang.String tuition.page.Home.onLogin()' on $Home_0@1d35bf2[Home]: Hibernate operation: Cannot open connection; uncategorized SQLException for SQL [???]; SQL state [null]; error code [0]; Cannot create PoolableConnectionFactory (The connection attempt failed.); nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (The connection attempt failed.) ------------------------------------------------------------------------------------- The ''java.lang.String tuition.page.Home.onLogin()'' is a simple method which queries database for a user name and a password. Any hints much appreciated!

This could be because of an incorrect URL or password or similar. Recheck your connection information and look at the server error log for more information about the failed connection. Kris Jurka
