Class WebLogicPlatform

java.lang.Object
  org.eclipse.persistence.platform.server.ServerPlatformBase
      org.eclipse.persistence.platform.server.wls.WebLogicPlatform

All Implemented Interfaces:

ServerPlatform

Direct Known Subclasses:

WebLogic_9_Platform

public class WebLogicPlatform
extends ServerPlatformBase

PUBLIC: This is the concrete subclass responsible for representing WebLogic-specific server behavior.

This platform overrides:

• getExternalTransactionControllerClass(): to use the WebLogic-specific controller class
• getServerNameAndVersion(): to call the WebLogic library for this information

Constructor Detail

WebLogicPlatform

public WebLogicPlatform(DatabaseSession newDatabaseSession)

INTERNAL: Default Constructor: All behavior for the default constructor is inherited.

Method Detail

initializeServerNameAndVersion

public void initializeServerNameAndVersion()

INTERNAL: Set the WLS version number through reflection.

getApplicationName

public 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" - we override this behavior here for WebLogic. There are 4 levels of implementation. 1) use the property override weblogic.applicationName, or 2) perform a reflective weblogic.work.executeThreadRuntime.getApplicationName() call (build 10.3+), or 3) extract the moduleName:persistence_unit from the weblogic classloader string representation (build 10.3), or 3) defer to superclass - usually return "unknown"

Returns:

String applicationName

getExternalTransactionControllerClass

public Class getExternalTransactionControllerClass()

INTERNAL: getExternalTransactionControllerClass(): Answer the class of external transaction controller to use for WebLogic. This is read-only.

Specified by:

getExternalTransactionControllerClass in interface ServerPlatform

Specified by:

getExternalTransactionControllerClass in class ServerPlatformBase

Returns:

Class externalTransactionControllerClass

See Also:

JTATransactionController, ServerPlatformBase.isJTAEnabled(), ServerPlatformBase.disableJTA(), ServerPlatformBase.initializeExternalTransactionController()

unwrapConnection

public Connection unwrapConnection(Connection connection)

Unwraps the WebLogic JDBC connection wrapping using the WebLogic API reflectively.

Specified by:

unwrapConnection in interface ServerPlatform

Overrides:

unwrapConnection in class ServerPlatformBase

clearStatementCache

public void clearStatementCache(Connection connection)

INTERNAL: Clears statement cache of WebLogic connection using the WebLogic API reflectively. Required by Oracle proxy authentication: currently connection statement cache becomes invalid on switching to/from proxy session. This method is called by OracleJDBC_10_1_0_2ProxyConnectionCustomizer before opening proxy session and before closing it.

Specified by:

clearStatementCache in interface ServerPlatform

Overrides:

clearStatementCache in class ServerPlatformBase
