Class StaffMgmtUserPrefsServiceFactory

java.lang.Object
  de.danet.an.util.userprefs.UserPrefsServiceFactory
      de.danet.an.staffmgmt.userprefs.StaffMgmtUserPrefsServiceFactory

public class StaffMgmtUserPrefsServiceFactory
extends de.danet.an.util.userprefs.UserPrefsServiceFactory

Implements a user preferences service factory based on the staffmgmt package.

Usage of this class as service factory requires an additional configuration parameter. The service factory implementation needs to connect to the staff directory EJB. In order to do so, it needs a JNDI name to look up the home interface. As JNDI names must be changeable by the application deployer, the name can't be hard coded.

This factory therefore uses the following ordered lookup procedure to determine the JNDI name of the staff directory EJB home interface:

Look for a name in java:comp/env/de.danet.an.staffmgmt.userprefs.staffDirectory. The complete configuration for StaffMgmtUserPrefsServiceFactory as user preferences service thus looks like:

<env-entry>
   <description>Configure the user prefs factory</description>
   <env-entry-name>de.danet.an.util.UserPrefsServiceFactory</env-entry-name>
   <env-entry-type>java.lang.String</env-entry-type>
   <env-entry-value>de.danet.an.staffmgmt.StaffMgmtUserPrefsServiceFactory</env-entry-value>
 </env-entry>
 <env-entry>
   <description>Configure the chosen factory</description>
   <env-entry-name>de.danet.an.staffmgmt.userprefs.StaffDirectory</env-entry-name>
   <env-entry-type>java.lang.String</env-entry-type>
   <env-entry-value>JNDI name of StaffDirectory EJB home</env-entry-value>
 </env-entry>

Note that these environment entries must be inserted in the ejb-jar.xml or web.xml for every EJB resp. servlet that calls the newInstance>newInstance 55 method of UserPrefsServiceFactory.

Find the application resource file de.danet.an.staffmgmt-userprefs.properties and look for an entry "staffDirectory = JNDI name of StaffDirectory EJB home".
Use the fallback JNDI name de.danet.an.staffmgmt.StaffDirectory.
