Class JDBCGroupProvider

java.lang.Object
  org.jivesoftware.openfire.group.JDBCGroupProvider

All Implemented Interfaces:

GroupProvider

public class JDBCGroupProvider
extends Object
implements GroupProvider

The JDBC group provider allows you to use an external database to define the make up of groups. It is best used with the JDBCAuthProvider to provide integration between your external system and Openfire. All data is treated as read-only so any set operations will result in an exception. To enable this provider, set the following in the system properties:

• provider.group.className = org.jivesoftware.openfire.group.JDBCGroupProvider

Then you need to set your driver, connection string and SQL statements:

• jdbcProvider.driver = com.mysql.jdbc.Driver
• jdbcProvider.connectionString = jdbc:mysql://localhost/dbname?user=username&password=secret
• jdbcGroupProvider.groupCountSQL = SELECT count(*) FROM myGroups
• jdbcGroupProvider.allGroupsSQL = SELECT groupName FROM myGroups
• jdbcGroupProvider.userGroupsSQL = SELECT groupName FORM myGroupUsers WHERE username=?
• jdbcGroupProvider.descriptionSQL = SELECT groupDescription FROM myGroups WHERE groupName=?
• jdbcGroupProvider.loadMembersSQL = SELECT username FORM myGroupUsers WHERE groupName=? AND isAdmin='N'
• jdbcGroupProvider.loadAdminsSQL = SELECT username FORM myGroupUsers WHERE groupName=? AND isAdmin='Y'

In order to use the configured JDBC connection provider do not use a JDBC connection string, set the following property

• jdbcGroupProvider.useConnectionProvider = true
