that should work for you Tony. I have a similar setup and mine works properly.

First, my setup is: Apache Tomcat 5.5.23 running as windows service JVM 1.5.0_12-b04 (Sun) Windows 2003 Server Apache is installed in C:\Apache\Tomcat. The location of the XML files is C:\Apache\Tomcat\conf\context.xml and C:\Apache\Tomcat\webapps\Reports\WEB-INF\web.xml. I added the following to the context.xml: <Resource name="jdbc/myDatabase" auth="Container" type="javax.sql.DataSource" driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver" initialSize="5" maxActive="-1" maxIdle="-1" minIdle="0" maxWait="10000" url="jdbc:sqlserver://<servername>\<instance>;integratedSecurity=true;da tabaseName=ReportingSupport" username="" password="" validationQuery="SELECT 1" testOnBorrow="true" testOnReturn="true" testWhileIdle="true" timeBetweenEvictionRunsMillis="60000" numTestsPerEvictionRun="5" minEvictableIdleTimeMillis="600000" poolPreparedStatements="true" maxOpenPreparedStatements="0" removeAbandoned="true" removeAbandonedTimeout="300" logAbandoned="true" /> I added the following to the web.xml (within the <web-app> tag): <resource-ref> <description>Resource for connecting to the SQL Server</description> <res-ref-name>jdbc/myDatabase</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> In my code I simply do: Context initCtx = new InitialContext(); Context envCtx = (Context)initCtx.lookup("java:comp/env"); DataSource ds = (DataSource)envCtx.lookup("jdbc/myDatabase"); Connection conn = ds.getConnection(); ...do something... conn.close(); Now, my goal is to utilize connection pooling. Does (a) this implementation achieve that and (b) the close statement suffice to return the object to the pool and not actually close the connection? Or do I also need to set "conn = null;"?

This looks like what I need. Now to go read up a bit more to grasp the concept.

We replaced the default authentication class of the product with our own implementation. This resulted in a Java class that performs many database calls to SQL Server 2005. This all works and I'm in a mode of optimizing it and found that I'm creating a database connection for every call (sometimes a single action sends many requests). I've been researching options for implementing connection pooling but I have found many variations and no really solid examples. I'm pretty new to Java / Tomcat so I'm in search of suggestions and recommendations from more experienced individuals on the following topics: * How configure a JNDI resource (versus hardcoding the connection in the class - which is what I do now). I've tried this with some examples and have been unable to get it to work. * How can I implement connection pooling? Do I need to roll my own solution or is there a magical way to tap into Tomcat and allow it to manage the connection pool (latter is preferred). Config file and Java code examples would be very helpful as well. Also, keep in mind that even though the JVM is at 1.5, the product is compiled at 1.4 if that makes a difference. Thanks!
