A database driver is used to specify the type of database and driver jar files that are required to connect to that database. Database jar files are drivers that are used to connect to database servers. There are specific jar files for a specific database server. These jar files are available with the database servers. Driver jar files can also be obtained from the following locations:

Oracle Server

Steps to create a Database Driver

Click Configure > ACCOUNTS > Database Driver.
Click CREATE Database Driver.
On Create Database Driver window, enter the name and description of the new Database Source in the Name and Description textboxes respectively.
In the Upload Driver Jar File(s), browse to and upload the driver jar files for the database.

On the Upload Jar File window, browse to and select the jar file. The path of the selected jar file is displayed in the Browse File text box.

A list of required Jar files for different databases is in the following table.

Database Servers	Driver Jar Files
Oracle	Classes12.jar For Oracle BLOB Data type: base.jar, oracle.jar and util.jar
IBM DB2 (Ver 7.1)	db2java.zip (7.1 version)
IBM DB2 (Ver 8.1)	db2jcc.jar
MS SQL	msbase.jar, mssqlServer.jar and msutil.jar
JTDS-SQL Server	Jtds.jar
HSQL DB	hsqldb-1.7.2.jar

Click Upload JAR. The file name is displayed under the heading File Names.
Repeat steps 5 to 6 to upload additional jar files.

If required, you can also unload the JAR files. To unload jar files, click Unload JAR.
Click Finish to return to the Create Database Driver Info window. The uploaded jar file(s) is displayed in the Upload Driver Jar File(s) field.

Enter the main class name of the database in the Driver Main Class Name. Driver Main Class Name is a fully qualified Java class name for the main database driver class. The driver class name typically starts with a com., net. or org. followed by the company domain.

For example, the JDBC driver class for mysql.com is called com.mysql.jdbc.Driver. Click Get Driver Class to select the Database Driver Main Class Definition from the Select Class drop-down list.

Click Submit. A list of Driver Main Class Name of different databases appears.

Database Servers	Driver Main Class Definition
Oracle	oracle.jdbc.driver.OracleDriver For Oracle BLOB Data type: com.ddtek.jdbc.oracle.OracleDriver
IBM DB2 (Ver 7.1)	COM.ibm.db2.jdbc.net.DB2Driver
IBM DB2 (Ver 8.1)	com.ibm.db2.jcc.DB2Driver
MS SQL	com.microsoft.jdbc.sqlServer.SQLServerDriver
JTDS-SQL Server	net.sourceforge.jtds.jdbc.Driver
HSQLDB	org.hsqldb.jdbcDriver
MS Access	sun.jdbc.odbc.JdbcOdbcDriver
MS Excel	sun.jdbc.odbc.JdbcOdbcDriver

Expand Advanced Properties and select the project of the activity from the drop-down list of Project.
