Re: Need Help w. Servlets And The JDBC.
You can configure a tomcat datasource to get a connection or you can load your database driver and get a connection object. The advantage with using tomcat datasource is that it will handle connection pooling for you. The tomcat docs explain how to define a datasource (you have to do it in context.xml) , also you will need the JDBC drivers for whatever database you are connecting to. -Sameer --- Steve R Burrus [EMAIL PROTECTED] wrote: Hi all.

Re: Need Help w. Servlets And The JDBC.
I don't suppose that on the Tomcat site there is a Type 4 database driver , which I have read is the preferred driver to get because it is pure Java, is there instead of the 1 which I assume I can always get at java.sun.com?

I am currently using the Microsoft SQL Server 2005 JDBC Driver. It is free. If you need to connect to a SQL Server 2000 or 2005, this is a good driver.

Re: Need Help w. Servlets And The JDBC.
Well this Microsoft SQL Server 2005 JDBC Driver. is it a Type 4 pure Java driver or not?? I should think that anything from Microsoft would tend to kind of de-emphasize Java.

I would be interested in seeing a TypeIV JDBC driver for that DB- yeas ago we had a similar situation using a bridge (JDBC-ODBC) that was considerably slow until the vendor supplied driver was supplied ..

Need Help w. Servlets And The JDBC.
Hi all. I am an admitted newbie when it comes to using a database connection for a servlet to access. So can someone please tell me the basics about how exactly I should go about doing this?? I have been very much stumped about how I should do this for quite a long time now! I just know that I should use 1 of 3 getConnection( ) methods to start to do this and create a Connection object but little else. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Need Help w. Servlets And The JDBC.
Adding to that, you should try using a connection pool rather than direct JDBC connection, once you get familiar with the fundamentals. With connection pools the application performs better than not.
