Subject [DBCP]: Tomcat+MySQL. Intermitent DbcpException: Server configuration denies access to data source
Date Mon, 11 Aug 2003 15:22:40 GMT


Hi!


I'm using Tomcat 4.1.24 with Apache 2 and MySQL 4.0.13. I have the mysql-
connector-java-2.0.14-bin.jar in commons/lib.
The application runs normally, and usually about once or twice a day I get
this exception org.apache.commons.dbcp.DbcpException:
java.sql.SQLException: Server configuration denies access to data source.
Once the exception occurs, it happens for every request and Tomcat needs
restarting.

Before getting this exception, I used to run out of connections, and
therefore I added to the server.xml

        <parameter>
          <name>logAbandoned</name>
          <value>true</value>
        </parameter>
        <parameter>
          <name>removeAbandoned</name>
          <value>true</value>
        </parameter>

I guess it could be related...

I include the exception and my server.xml file.

Any help appreciated.


Monica
