i m using mysql driver on tomcat webserver and using JNDI based connectionpooling. and i made a connection succesfully.
i have made a connection accordingly as given in tomcat documentation on Connection pooling.
i have a number of querys
1. In the initial context , why we write string "java:/comp/env" what its significance ? Does it point to particular location in the tomcat?
2. I have used org.apache.commons.dbcp.BasicDataSourceFactory . Does this class do the connection pooling? I think its just implementing data source interface. please explain. i have used a commons-dbcp-1.2.1.jar . and also i used mysql-connector-java-3.1.10-bin.jar for driver
3. there is MysqlConnectionPoolDataSource.class and MysqlDatasource.class in mysql-connector-java-3.1.10-bin.jar . Can I use this file for connection pooling and datasource connection . If yes then how shd i do it ? please explain.
4. I also want to make a class file for connection pooling instead of relying on tomcat to do the connection pooling for me. can i use these jar files for my own connection pooling? if yes then how should i do it ? please explain.
