DADX Groups

DB2 Web Services are defined using DADX files. Collections of one or more DADX files are called DADX groups and are stored in a directory by the same name. The samples application contains two DADX groups, dxx_sample and dxx_travel. Besides DADX files, the group also contains other files associated with the definition of the service, such as the properties common to the group.

Group Properties
The properties of a group are stored in the group.properties file, found in the group directory. The group.properties file can be created using a text editor, or using the WebSphere Studio Web Service DADX Group Configuration wizard. Below are some of the group properties to be set:

• dbDriver: the appropriate iSeries native JDBC driver. This should be set to com.ibm.db2.jdbc.app.DB2Driver
• dbURL: the iSeries database.
• userID: an iSeries user profile to be used when access the database. If not specified, the user profile associated with the application server is used. By default, the application server runs under QEJBSVR. The user profile used must be authorized to any database objects accessed. For stored procedures, this includes the *PGM object that is created for each CREATE PROCEDURE statement. For Java stored procedures, the user (or *PUBLIC) must also be authorized to the Java class file.
• password: the user profile password for the user profile specified for the userID property. By default, the password is stored in the group.properties files in plain text. Refer to Security if you would like to encode the password.
