Also, the "debug" attribute has not been valid for quite some time. Do you really need "crossContext", "antiJARLocking", and "antiResourceLocking" attributes? > <Resource name="jdbc/atvd" type="javax.sql.DataSource" > auth="container" username="atvd" password="atvd" > driverClassName="com.mysql.jdbc.Driver" > url="jdbc:mysql://localhost:3306/atvd12?autoReconnect=true" /> This looks okay to me, though it's typical to set the "maxActive" and "maxIdle" attributes here to size your connection pool. The defaults are maxActive=8 and maxIdle=8 FYI. In development, I *highly* recommend that you set maxActive=1. I usually recommend adding a "validationQuery" plus "removeAbandoned", "logAbandoned", and set a reasonable "removeAbandonedTimeout" (I use "30" to specify a 30-second timeout). A good validationQuery for MySQL is "/* ping */ SELECT 1" because the driver will use a lightweight ping instead of actually issuing a SQL query to the server: it reduces some useless overhead. > Unfortunately I'm Getting below error.

Have you checked logs/catalina.out or anything else in logs/? You said there was no special information... does it just have the same stack trace or is there nothing? I know nothing about Hibernate, but you may have to post your Hibernate configuration in order to get any further, here. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with undefined - http://www.enigmail.net/ iEYEAREIAAYFAlDt4wgACgkQ9CaO5/Lv0PDqAACcCU37VTsGS2C5EBRHLQ7nJPfk YtkAn1Xf0zaWueMWx48a5Yh6VF+nciCk =kpR3 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
