Class SessionManager

java.lang.Object
  oracle.toplink.tools.sessionmanagement.SessionManager

public class SessionManager
extends java.lang.Object

Purpose: Global session location.

Description: This allows for a global session local which can be accessed globally from other classes. This is needed for EJB data stores as they must have a globally accessible place to access the session. This can be by EJB session beans, BMP beans and CMP beans as well as Servlets and other three-tier services.

Responsibilities:

• Store a global session.
• Allow the storage of alternative sessions as well.

Since:

TOPLink/Java 3.0

Constructor Detail

SessionManager

public SessionManager()

The default constructor to create a new session manager.

Method Detail

shouldUseSchemaValidation

public static boolean shouldUseSchemaValidation()

Return if schema validation will be used when parsing the 10g (10.1.3) sessions XML.

setShouldUseSchemaValidation

public static void setShouldUseSchemaValidation(boolean value)

Set if schema validation will be used when parsing the 10g (10.1.3) sessions XML. By default schema validation is on, but can be turned off if validation problems occur, or to improve parsing performance.
