All Implemented Interfaces:

org.eclipse.persistence.platform.server.ServerPlatform

public class CDISEPlatform
extends org.eclipse.persistence.platform.server.JMXServerPlatformBase

A JMXServerPlatformBase that arranges things such that CDI, not JNDI, will be used to acquire a TransactionManager and MBeanServer.

Most users will not use this class directly, but will supply its fully-qualified name as the value of the eclipselink.target-server Eclipselink JPA extension property in a META-INF/persistence.xml file.

For example:

<property name="eclipselink.target-server"
          value="io.helidon.integrations.cdi.eclipselink.CDISEPlatform"/>

Constructor Details

CDISEPlatform

public CDISEPlatform(org.eclipse.persistence.sessions.DatabaseSession session)

Creates a CDISEPlatform.

Parameters:

session - the DatabaseSession this platform will wrap; must not be null

See Also:

• JMXServerPlatformBase(DatabaseSession)

Method Details

initializeServerNameAndVersion

protected void initializeServerNameAndVersion()

Sets the name of the platform.

The format of the platform name is subject to change without notice.

Overrides:

initializeServerNameAndVersion in class org.eclipse.persistence.platform.server.ServerPlatformBase

See Also:

• ServerPlatformBase.getServerNameAndVersion()

getMBeanServer

public MBeanServer getMBeanServer()

Uses CDI to find a relevant MBeanServer, caches it, and returns it.

This method may return null.

Overrides of this method may return null.

If there is no such MBeanServer then the MBeanServer found and cached by the superclass implementation of this method is returned instead.

Overrides:

getMBeanServer in class org.eclipse.persistence.platform.server.JMXServerPlatformBase

Returns:

an MBeanServer, or null

launchContainerRunnable

public void launchContainerRunnable(Runnable runnable)

Uses CDI to find a relevant Executor whose Executor.execute(Runnable) method will be used to submit the supplied Runnable.

If there is no such Executor, then the superclass implementation of this method is used instead.

Specified by:

launchContainerRunnable in interface org.eclipse.persistence.platform.server.ServerPlatform

Overrides:

launchContainerRunnable in class org.eclipse.persistence.platform.server.ServerPlatformBase

Parameters:

runnable - the Runnable to launch; should not be null

See Also:

• ServerPlatformBase.launchContainerRunnable(Runnable)

initializeExternalTransactionController

public void initializeExternalTransactionController()

Overrides the ServerPlatformBase.initializeExternalTransactionController() method to disable JTA if there is no TransactionManager bean present in CDI before invoking the superclass implementation.

This method also acquires a DataSource from CDI proactively, and installs it to preëmpt any JNDI operations.

Specified by:

initializeExternalTransactionController in interface org.eclipse.persistence.platform.server.ServerPlatform

Overrides:

initializeExternalTransactionController in class org.eclipse.persistence.platform.server.ServerPlatformBase

Throws:

org.eclipse.persistence.exceptions.ValidationException - if a DataSource could not be acquired

See Also:

• ServerPlatformBase.initializeExternalTransactionController()
• Session.getDatasourceLogin()
• DatasourceLogin.getConnector()
• JNDIConnector
• JNDIConnector.getName()
• JNDIConnector.setDataSource(DataSource)

getExternalTransactionControllerClass

public Class<? extends org.eclipse.persistence.sessions.ExternalTransactionController> getExternalTransactionControllerClass()

Returns a non-null Class that extends AbstractTransactionController, namely CDISEPlatform.TransactionController.

Specified by:

getExternalTransactionControllerClass in interface org.eclipse.persistence.platform.server.ServerPlatform

Specified by:

getExternalTransactionControllerClass in class org.eclipse.persistence.platform.server.ServerPlatformBase

Returns:

a non-null Class that extends AbstractTransactionController

See Also:

• AbstractTransactionController
• CDISEPlatform.TransactionController

getJNDIConnectorLookupType

public final int getJNDIConnectorLookupType()

Returns JNDIConnector.UNDEFINED_LOOKUP when invoked.

Specified by:

getJNDIConnectorLookupType in interface org.eclipse.persistence.platform.server.ServerPlatform

Overrides:

getJNDIConnectorLookupType in class org.eclipse.persistence.platform.server.ServerPlatformBase

Returns:

JNDIConnector.UNDEFINED_LOOKUP

unwrapConnection

public Connection unwrapConnection(Connection c)

Overrides the ServerPlatformBase.unwrapConnection(Connection) method to consider DelegatingConnections.

By design, only one level of unwrapping occurs; i.e. if the unwrapped Connection is itself a DelegatingConnection it is returned as is.

Specified by:

unwrapConnection in interface org.eclipse.persistence.platform.server.ServerPlatform

Overrides:

unwrapConnection in class org.eclipse.persistence.platform.server.ServerPlatformBase

Parameters:

c - the Connection to unwrap; must not be null

Returns:

the unwrapped Connection (which may be the supplied Connection); never null

Throws:

NullPointerException - if c is null

• ServerPlatformBase.unwrapConnection(Connection)
