JNDI-based data sources are a feature of any J2EE app server, and some servlet containers (such as Tomcat). They can easily be used in a Struts Action. One of the many conveniences of this approach is that the resources are configured externally -- you don't need to mess with web.xml or struts-config.xml for them. So, for example, the exact same WAR file can be deployed on a test machine and a production machine, with the server resource configuration pointing you at the appropriate test or production database. Configuration details will depend on your server -- here's the docs for Tomcat: http://jakarta.apache.org/tomcat/tomcat-4.1-docs/jndi-resources-howto.html http://jakarta.apache.org/tomcat/tomcat-4.1-docs/jndi-datasource-examples-howto.html Regards, Jailani.S Craig - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

How to use datasource and db connection pooling in struts?
Hi, there! How can I easily achieve database connection pooling (using a datasource in one of the xml config files - btw. which one is it?)? I know there is some stuff in jakarta-commons. What I want to achieve is an easy to configure and highly efficient db connection pool that is available to all my action classes.

RE: How to use datasource and db connection pooling in struts?
Taking advantage of this thread. Has any of you had the experience of using a connection provided by the Websphere pool to handle connected components, i.e. Struct or ARRAY in Oracle. We are getting a ClassCastException since driver attempts to cast the connection to an OracleConnection, and WAS pool provided connection does not implement OracleConnection since is a connection provided by IBM classes. Any workaround? We are stuck with this issue. If you ask to IBM support they probably response you to use DB2 so not really helpful. Any experience? TIA, Adolfo. From: Hajratwala, Nayan (N.)

Re: How to use datasource and db connection pooling in struts?
struts-config.xml is where you define your datasources. You specify the key to store the DataSource object under in the application scope so your actions can find it later. You also have to specify the DataSource implementation class to use. Often this will be provided by your database vendor but if it isn't, you can use the datasource provided by jakarta-commons dbcp BasicDataSource as suggested in a previous reply.

Re: How to use datasource and db connection pooling in struts?
For that one you need to play RTFM with your server docs. It should be possible, but the way you do it would be container-dependant. Tomcat will place a reference into JNDI for you - I assume (dangerous as it is) other will too. If you are using a different server than Tomcat, and it doesn't allow you to specify a data-source in server.xml, you could always initialize a JNDI data-source in a start-up servlet -- or in a struts plugin. You could also use a singleton pattern. [EMAIL PROTECTED] wrote: You were too fast for me ... Anyway, is it possible to define datasources for webapps NOT using struts except for using server.xml?

Thanks for this hint. I am using tomcat 99% of the time, so it shouldn't be to bad. However I like the traditional start-up servlet method better. Happen to have any code on this (e.g. a start-up servlet...)? I know old school pooling used start-up servlets too, and then you had to leave the pool in the context.

Re: How to use datasource and db connection pooling in struts?
I use Tomcat 100% of the time, so, no, I don't have code to initialize the data-source. Sorry :-( A ContextListener would also be another approach I forgot to mention. That's a servlet spec 2.3 thing - and would be even further independent of the particular app. Once written, you could drop into any app to init your data-source. If you find the need to externalize your configuration, see commons-digester -- it's a snap!

DB Connection Pooling
