Doesn’t answer the question about JDC in any way. The middleware component might use any other type of driver to provide the actual database access. Also can we use Class. The user of the application then adds a valid JDBC driver to the classpath and configuring things like a connection string so the application can actually to connect to a database.

What is the actual use of Class. It will not ‘start the class’. However, you must manually load any drivers prior to JDBC 4. If you do not need to use any methods, fields, or inner classes of the specified class, then Class. As mentioned earlier, databases have seemed from their inception to be in a constant state of turmoil, primarily because the demand for database applications, and thus database tools, is so great.

When you are selecting a driver, you need to balance sun.jdbc.odbc.jdbcodbccriver , reliability, and portability. One of the major problems with databases has been the feature wars between the database companies. An applet might need to use a Type 3 driver to get around a firewall.

Of course, this process can vary radically from machine to machine, but the process I used to make it work under bit Windows might give you clues to help you attack your own situation. Doesn’t answer the question about JDC in any way.

One reason most programs call Class. I don’t think Class.

Since the bridge makes extensive use of native method calls, it is not recommended for long-term or high-volume deployment. A standalone, GUI-intensive program that always runs on a Windows NT system will benefit from the additional speed of a Type 2, native-code driver.

I’ve just downloaded mysql-connector-java JDBC also provides some additional mechanisms to address this, eg JDBC escapes to provide a common syntax that the driver translates meaninb the specific syntax, and DatabaseMetaData which allows you to discover features, reserved words etc which allow you to create or generate compatible queries.


I used Microsoft Query that came with Microsoft Office, but you might prefer something else. But the theory is that your application can be database independent. Connecting to the Database. Driver implementations in that jar.

The bridge was originally written to allow the developer community to get up and running quickly with JDBC. If the default constructor is not defined, then we have to invoke the defiend constructor using reflection API.

These days the magic hooks are present allowing the JVM to autodiscover the drivers if new enough so the call is superfluous, but out of habit many still ot it.

This is typically done by loading the driver class using the Class. The reason why Class. So we can pass the class name dynamically. Driver class is in there.
