68 Getting Started with WebSphere Application Server Community Edition Type 2 and Type 4 IBM Data Server Driver for JDBC and SQLJ Table 4.1 - DB2 JDBC and SQLJ drivers db2jcc.jar and sqlj.zip db2jcc4.jar and sqlj4.zip * Deprecated means it is still supported, but no longer enhanced JDBC 3.0 compliant JDBC 4.0 and earlier 1.4.2 6 As you can see from Table 4.1, Type 2 is provided with two different drivers; however the DB2 JDBC Type 2 Driver for Linux, UNIX and Windows, packaged as db2java.zip, is deprecated. The IBM Data Server Driver for JDBC and SQLJ packaged as db2jcc.jar (com.ibm.db2.jcc) includes support for both, the type 2 and type 4 drivers. The choice of driver is determined based on the syntax used to connect to the database in your Java program: If a hostname or IP address, and a port are included in the connection string, then type 4 is used, otherwise, type 2 is used. The IBM Data Server Driver for JDBC and SQLJ has been optimized to access all DB2 servers in all platforms including the mainframe. When you install a DB2 server, a DB2 client or the IBM Data Server Driver for JDBC and SQLJ, the db2jcc.jar and sqlj.zip files compliant with JDBC 3.0 are automatically added to your CLASSPATH. If you would like to use the JDBC 4.0 specification, make sure to replace db2jcc.jar and sqlj.zip with db2jcc4.jar and sqlj4.zip respectively in the CLASSPATH. Note: For more information about JDBC drivers, refer to the eBook Getting started with DB2 Express-C. If you are new to the Java programming language and the Java EE framework, review the eBook Getting Started with Java. Both books are part of this book series. In this book we use the JDBC 4 compliant driver packaged in file db2jcc4.jar that is included with DB2 Express-C under C:\Program Files\IBM\SQLLIB\Java on Windows or /opt/ibm/db2/V9.7/java on Linux. Note that db2jcc4.jar requires Java 6. To install the JDBC driver in Community Edition follow these steps: 1. Start the Community Edition server if it is not started yet. Open a browser and log in to the Administrative Console using the user ID of system and the password of manager: https://localhost:8443/console 2. In the Console Navigation section on the left panel, under the Services folder, click on Repository to open the repository viewer portlet as shown in Figure 4.3.
Chapter 4 – Working with databases 69 Figure 4.3 - The repository viewer 3. At the top of the repository viewer, you can add new archives, and in the lower section you can view the current repository entries. Community Edition bundles several JDBC drivers for different DB2 versions. You can choose one according to your DB2 version. If there is no repository entry for DB2 9.7 (an entry for com.ibm.db2/db2jcc4/9.7/jar), you can add it as explained in the next steps. 4. Click the Browse button to locate the JDBC driver db2jcc4.jar in your DB2 installation directory (for example, C:\Program Files\IBM\SQLLIB\java on Windows). Then input a Group ID, Artifact ID, Version, and Type information as shown in Figure 4.4.
