Class JDBCGroupProvider

java.lang.Object
  org.jivesoftware.wildfire.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 Wildfire. 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 XML configuration file:

 <provider>
     <group>
         <className>org.jivesoftware.wildfire.group.JDBCGroupProvider</className>
     </group>
 </provider>
 

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

 <jdbcProvider>
     <driver>com.mysql.jdbc.Driver</driver>
     <connectionString>jdbc:mysql://localhost/dbname?user=username&password=secret</connectionString>
 </jdbcProvider>

 <jdbcGroupProvider>
      <groupCountSQL>SELECT count(*) FROM myGroups</groupCountSQL>
      <allGroupsSQL>SELECT groupName FROM myGroups</allGroupsSQL>
      <userGroupsSQL>SELECT groupName FORM myGroupUsers WHERE
 username=?</userGroupsSQL>
      <descriptionSQL>SELECT groupDescription FROM myGroups WHERE
 groupName=?</descriptionSQL>
      <loadMembersSQL>SELECT username FORM myGroupUsers WHERE groupName=? AND
 isAdmin='N'</loadMembersSQL>
      <loadAdminsSQL>SELECT username FORM myGroupUsers WHERE groupName=? AND
 isAdmin='Y'</loadAdminsSQL>
 </jdbcGroupProvider>
