org.eclipse.persistence.platform.server
Class JMXServerPlatformBase

java.lang.Object
  extended by org.eclipse.persistence.platform.server.ServerPlatformBase
      extended by org.eclipse.persistence.platform.server.JMXServerPlatformBase
All Implemented Interfaces:
ServerPlatform
Direct Known Subclasses:
JBossPlatform, SunAS9ServerPlatform, WebLogicPlatform, WebSpherePlatform

public abstract class JMXServerPlatformBase
extends ServerPlatformBase

PUBLIC: Subclass of org.eclipse.persistence.platform.server.ServerPlatformBase in support of the JMXEnabledPlatform interface

This is the abstract superclass of all platforms for all servers that contain a subclass that implements the JMXEnabledPlatform interface. Each DatabaseSession contains an instance of the receiver, to help the DatabaseSession determine:

Subclasses already exist to provide configurations for Oc4J, WebLogic, JBoss, NetWeaver, GlassFish and WebSphere.

If the versioned platform subclass is JMX enabled by EclipseLink (registers MBeans) then that server platform must implement the JMXEnabledPlatform interface To provide some different behavior than the provided ServerPlatform(s), we recommend subclassing org.eclipse.persistence.platform.server.JMXServerPlatformBase (or a subclass), and overriding:

for the desired behavior.

Constructor Detail

JMXServerPlatformBase

public JMXServerPlatformBase(DatabaseSession newDatabaseSession)
INTERNAL: Default Constructor: Initialize so that runtime services and JTA are enabled.

Method Detail

getAbstractSession

protected org.eclipse.persistence.internal.sessions.AbstractSession getAbstractSession()
Return the AbstractSession required to log to the non-platform EclipseLink log. Note: The WeblogicEclipseLinkLog defined for the WebLogic platform currently only supports the following logging categories in the categoryMap HashMap {connection=DebugJpaJdbcJdbc, cache=DebugJpaDataCache, transaction=DebugJpaJdbcJdbc, weaver=DebugJpaEnhance, query=DebugJpaQuery, dms=DebugJpaProfile, sequencing=DebugJpaRuntime, properties=DebugJpaRuntime, ejb=DebugJpaRuntime, jpa_metamodel=DebugJpaMetaData, sql=DebugJpaJdbcSql, ejb_or_metadata=DebugJpaMetaData, event=DebugJpaRuntime, server=DebugJpaRuntime, propagation=DebugJpaDataCache}


getMBeanServer

public javax.management.MBeanServer getMBeanServer()
INTERNAL: Return the MBeanServer to be used for MBean registration and deregistration.
This MBeanServer reference is lazy loaded and cached on the platform.
There are multiple ways of getting the MBeanServer

1) MBeanServerFactory static function - working for 3 of 4 servers WebSphere, JBoss and Glassfish in a generic way
- JBoss returns 2 MBeanServers in the List - but one of them has a null domain - we don't use that one
- WebLogic may return 2 MBeanServers - in that case we want to register with the one containing the "com.bea" tree 2) ManagementFactory static function - what is the difference in using this one over the one returning a List of servers
3) JNDI lookup
4) Direct server specific native API

We are using method (1)

Returns:
the JMX specification MBeanServer

serverSpecificRegisterMBean

public void serverSpecificRegisterMBean()
INTERNAL: serverSpecificRegisterMBean(): Server specific implementation of the creation and deployment of the JMX MBean to provide runtime services for my databaseSession. Default is to do nothing. This should be subclassed if required. For platform classes that override the JMXEnabledPlatform - the services MBean is created at platform construction for use during MBean registration here.

Overrides:
serverSpecificRegisterMBean in class ServerPlatformBase
See Also:
ServerPlatformBase.isRuntimeServicesEnabled(), ServerPlatformBase.disableRuntimeServices(), ServerPlatformBase.registerMBean()

serverSpecificUnregisterMBean

public void serverSpecificUnregisterMBean()
INTERNAL: serverSpecificUnregisterMBean(): Server specific implementation of the de-registration of the JMX MBean from its server during session logout.

Overrides:
serverSpecificUnregisterMBean in class ServerPlatformBase
See Also:
ServerPlatformBase.isRuntimeServicesEnabled(), ServerPlatformBase.disableRuntimeServices()

getMBeanSessionName

protected java.lang.String getMBeanSessionName()
Remove JMX reserved characters from the session name

Parameters:
aSession -
Returns:

getRuntimeServicesMBean

protected MBeanRuntimeServicesMBean getRuntimeServicesMBean()
INTERNAL: Return the cached server specific services MBean


setRuntimeServicesMBean

protected void setRuntimeServicesMBean(MBeanRuntimeServicesMBean runtimeServicesMBean)
INTERNAL: Set the cached server specific services MBean

Parameters:
runtimeServicesMBean -

getModuleName

protected java.lang.String getModuleName(boolean enableDefault)
INTERNAL:

Parameters:
enableDefault -
Returns:

getModuleName

public java.lang.String getModuleName()
INTERNAL: getModuleName(): Answer the name of the context-root of the application that this session is associated with. Answer "unknown" if there is no module name available. Default behavior is to return "unknown" - we override this behavior here for JBoss. There are 4 levels of implementation. 1) use the property override jboss.moduleName, or 2) perform a reflective jboss.work.executeThreadRuntime.getModuleName() call, or 3) extract the moduleName:persistence_unit from the server specific classloader string representation, or 3) defer to superclass - usually return "unknown"

Specified by:
getModuleName in interface ServerPlatform
Overrides:
getModuleName in class ServerPlatformBase
Returns:
String moduleName

setModuleName

protected void setModuleName(java.lang.String aName)
INTERNAL;

Parameters:
aName -

getApplicationName

protected java.lang.String getApplicationName(boolean enableDefault)
INTERNAL: Lazy initialize the application name by first checking for a persistence.xml property override and then deferring to a default name in the absence of a platform override of this function

Parameters:
enableDefault -
Returns:

getApplicationName

public java.lang.String getApplicationName()
INTERNAL: getApplicationName(): Answer the name of the module (EAR name) that this session is associated with. Answer "unknown" if there is no application name available. Default behavior is to return "unknown" There are 4 levels of implementation. 1) use the property override weblogic.applicationName, or 2) perform a reflective weblogic.work.executeThreadRuntime.getApplicationName() call, or 3) extract the moduleName:persistence_unit from the application classloader string representation, or 3) defer to this superclass - usually return "unknown"

Returns:
String applicationName

JMXEnabledPlatform

setApplicationName

public void setApplicationName(java.lang.String aName)
INTERNAL:

Parameters:
aName -

initializeApplicationNameAndModuleName

protected void initializeApplicationNameAndModuleName()
INTERNAL: Get the applicationName and moduleName from the application server. This function does not use reflective API on the application server, instead it parses the database session name for the module name, and the classLoader (from the Platform.conversionManager) toString() for the application name.
