Method Detail

createApplicationModule

public ApplicationModule createApplicationModule(SessionCookie cookie,
                                                 EnvInfoProvider envInfo)

Description copied from interface: ConnectionStrategy

Create an application module. This operation is included in the connection strategy interface because location of an application module's home object may require a connection to another JNDI context.

Specified by:

createApplicationModule in interface ConnectionStrategy

Parameters:

cookie - the SessionCookie instance that requested the ApplicationModule

envInfo - the SessionCookie EnvInfoProvider if it exists. This parameter has been deprecated in 10.1.3. Applications should not use this parameter. The EnvInfoProvider will still be invoked by the ApplicationPool as documented in the EnvInfoProvider interface.

createApplicationModule

public ApplicationModule createApplicationModule(java.util.Hashtable environment)

Description copied from interface: ConnectionStrategy

Create an application module. This operation is included in the connection strategy interface because location of an application module's home object may require a connection to another JNDI context.

Specified by:

createApplicationModule in interface ConnectionStrategy

Parameters:

environment - the environment which is to be used to locate the application module home. Typically derived from the application module configuration.

connect

public void connect(ApplicationModule applicationModule,
                    SessionCookie cookie,
                    EnvInfoProvider envInfo)

Description copied from interface: ConnectionStrategy

Connect an application module.

Specified by:

connect in interface ConnectionStrategy

Parameters:

applicationModule - the ApplicationModule instance that is to be connected.

cookie - the SessionCookie instance that requested the ApplicationModule

envInfo - the SessionCookie EnvInfoProvider if it exists. This parameter has been deprecated in 10.1.3. Applications should not use this parameter. The EnvInfoProvider will still be invoked by the ApplicationPool as documented in the EnvInfoProvider interface.

reconnect

public void reconnect(ApplicationModule applicationModule,
                      SessionCookie cookie,
                      EnvInfoProvider envInfo)

Description copied from interface: ConnectionStrategy

Reconnect an application module

Specified by:

reconnect in interface ConnectionStrategy

Parameters:

applicationModule - the ApplicationModule instance that is to be reconnected.

cookie - the SessionCookie instance that requested the ApplicationModule

envInfo - the SessionCookie EnvInfoProvider if it exists. This parameter has been deprecated in 10.1.3. Applications should not use this parameter. The EnvInfoProvider will still be invoked by the ApplicationPool as documented in the EnvInfoProvider interface.

disconnect

public void disconnect(ApplicationModule applicationModule,
                       boolean retainState,
                       SessionCookie cookie)

Description copied from interface: ConnectionStrategy

Disconnect an application module

Specified by:

disconnect in interface ConnectionStrategy

Parameters:

applicationModule - the ApplicationModule instance that is to be disconnected.

cookie - the SessionCookie instance that requested the ApplicationModule // * @param envInfo the SessionCookie EnvInfoProvider if it exists. This // * parameter has been deprecated in 10.1.3. Applications should not // * use this parameter. The EnvInfoProvider will still be invoked // * by the ApplicationPool as documented in the EnvInfoProvider // * interface.

doHandleDatabaseState

public void doHandleDatabaseState(ApplicationModule appModule,
                                  ApplicationPoolSvcMsgContext ctx)
