I\'m using GWT with Hibernate, c3p0 and MySQL to produce a web app with a limited audience (max 50 users per day). During testing I found that Hibernate was opening a connection with each session but
I\'m using C3P0 as a connection pool in Tomcat, and I\'m seeing very worrying errors: 2010-09-16 13:25:00,160 [Timer-0] WARNcom.mchange.v2.asyn开发者_StackOverflow中文版c.ThreadPoolAsynchronousRunner
I\'m using Hibernate with MySQL and c3p0, and when the MySQL connection expires after 8 hours (wait_timeout), Hibernate is unable to reconnect and i get the following exception:
I\'m working on an application which uses the Spring framework in combination with Ibatis and a C3P0 Connection pool. The system connects to ab开发者_JAVA技巧out 12 seperate databases.
I have MySQL under my Hibernate and I am also using c3p0-0.9.1 for connection pool. When running on my laptop (I mean locally) I have no errors.
I\'m getting the following exception after my program runs for 30 minutes or so with 3cp0 as my connection pool.
I would like to set the testConnectionOnCheckin property for c3p0. However I am having trouble doing so because the c3p0 datasource is created on my behalf within a hibernate entity-manager bean.
This is an issue which I have seen all across the web. I will bring it up again as till now I don\'t have a fix for the same.
