I did not get the meaning of those parameters stating that active connections should be 100 and the other with 30 as the value. what is the difference between max active and inactive connections? and just a curious question, is tomcat really used on heavy duty commertial websites? thanks Krishnakant.

Facing problem with implementation of DBCP
Hi All, Iam facing problem with DBCP implementation from last one week.I followed all the instructions which are mentioned in the documentation section,but i could not implement it. When i run the Program which is involving DBCP, is showing the following error: java.sql.SQLException: Cannot load JDBC driver class 'null' . Normal JDBC Programs are working fine.I placed all the three jar files and Jdbc Driver(Mysql Connector) in $CATALINA_HOME/common/lib folder.(commons-collections.jar,commons-dbcp.jar, commons-pool.jar and mysql-connector-java-3.1.7-bin.jar) The configuration which iam using is: Linux Operating System (Redhat v 8.0) Mysql(v 3.23) Mysql Connector(3.1.7) Tomcat 4.1.24 J2sdk 1.4.1 I will be very glad to you,if you can assist me in resolving this issue. -- Ajay - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
