WebSphere Application Server - Express supports the IBM Toolbox for Java JDBC driver. This JDBC driver is included with the IBM Toolbox for Java product.
IBM Toolbox for Java is a library of Java classes that are optimized for accessing iSeries and AS/400 data and resources. You can use the IBM Toolbox for Java JDBC driver to access local or remote DB2 UDB for iSeries 400 databases from server-side and client-side Java applications that run on any platform that supports Java.
IBM Toolbox for Java is available in these versions:
IBM Toolbox for Java licensed program
The licensed program is available with every i5/OS release, Version 4 Release 2 (V4R2) or later. You can install the licensed program on your iSeries system, and then either copy the IBM Toolbox for Java JAR file (jt400.jar) to your system or update your system classpath to locate the server installation. For product documentation for IBM Toolbox for Java, see IBM Toolbox for Java.
JTOpen
JTOpen is the open source version of IBM Toolbox for Java, and is more frequently updated than the licensed program version. You can download JTOpen from the IBM Toolbox for Java: Downloads page. You can also download the JTOpen Programming Guide. The guide includes instructions for installing JTOpen, as well as information about the JDBC driver.
The JDBC driver for both versions supports JDBC 2.0. For more information about IBM Toolbox for Java and JTOpen, see the product Web site at http://www.ibm.com/servers/eserver/iseries/toolbox/index.html.
If you are running WebSphere Application Server - Express, Version 5, on a non-iSeries platform, download the JTOpen version of IBM Toolbox for Java.
To configure the jt400.jar file, do the following:
To use a Toolbox JDBC driver, select UDB DB2 for iSeries (Toolbox) or UDB DB2 for iSeries (Toolbox XA) when you create a new JDBC provider. When the provider is created, the classpath field contains this value: ${OS400_TOOLBOX_JDBC_DRIVER_PATH}/jt400.jar.
