Direct Known Subclasses:

CommerceProfileFailService

public class ProfileSessionFailService
extends GenericService
implements atg.servlet.sessionsaver.Restoreable

This service is used to preserve a user's active profile in the event of a session failover to another Dynamo server. This service backs up the user id of the profile for the session. The id is only saved if the user is not anonymous. If the profile is transient, then by default is nothing is backup.

To backup profile attributes of anonymous visitors, developers should subclass this class. JavaBean properties should be added which expose and record the desired attribute. The sessionRestored method can be overrode to then update the final profile with the desired saved attributes.

For example the subclass could have functionality similar to this:

 protected byte [] mShoppingCart;

 public void setShoppingCart(byte [] pShoppingCart) {
   mShoppingCart = pShoppingCart;
 }
 public byte [] getShoppingCart() {
   if (getProfile() != null)
     return (byte [])getProfile().getPropertyValue("shoppingCart");
   return null;
 }

 public void sessionRestored () {
   super.sessionRestored();
   if ((mShoppingCart != null) && (mShoppingCart.length > 0) &&
       (getProfile() != null)) {
     try {
       getProfileTools().updateProperty("shoppingCart", mShoppingCart, getProfile());
     }
     catch (RepositoryException exc) {
       if (isLoggingError())
         logError(exc);
     }
   }

Constructor Detail

public ProfileSessionFailService()

Constructs an instanceof ProfileSessionFailService

Method Detail

setProfileTools

public void setProfileTools(ProfileTools pProfileTools)

Sets property ProfileTools

getProfileTools

public ProfileTools getProfileTools()

Returns property ProfileTools

setProfile

public void setProfile(Profile pProfile)

Sets property Profile

getProfile

public Profile getProfile()

Returns property Profile

setUidForFailover

public void setUidForFailover(java.lang.String pUidForFailover)

Stores the uidForFailover parameter in the member variable mUidForFailover

getUidForFailover

public java.lang.String getUidForFailover()

Returns the user id of the profile. If the profile property is null, or the profile is anonymous then we return null to indicate that this user does not exist in the persistent repository.

setDataSource

public void setDataSource(RepositoryItem dataSource)

Set the datasource property on the profile associated with this service.

Parameters:

dataSource - The profile's datasource.

getDataSource

public RepositoryItem getDataSource()

Gets the datasource property of the profile associated with this service.

Returns:

The profile's datasource or null if the profile is null.

setFailedOverSecurityStatus

public void setFailedOverSecurityStatus(int pFailedOverSecurityStatus)

After a profile is failed over, the security status of the re-established profile will be set to this value. This allows a security conscious site to force relogin upon failover to plug any potential security holes during failover. Setting this value to -1 will allow the actual value to be failed over, but you will need to add the value to the list of properties to be failed over.

getFailedOverSecurityStatus

public int getFailedOverSecurityStatus()

sessionRestored

public void sessionRestored()

This restoring method takes the mUidForFailover member variable and attempts to load the profile with the given id. If mUidForFailover is null then this means that the user was anonymous and we do not attempt to load the profile from the database.
