javax.xml.rpc.handler

Class GenericHandler

public abstract class GenericHandler extends Object implements Handler

The javax.xml.rpc.handler.GenericHandler class implements the Handler interface. SOAP Message Handler developers should typically subclass GenericHandler class unless the Handler class needs another class as a superclass.

The GenericHandler class is a convenience abstract class that makes writing Handlers easy. This class provides default implementations of the lifecycle methods init and destroy and also different handle methods. A Handler developer should only override methods that it needs to specialize as part of the derived Handler implementation class.

Constructor Summary
protected GenericHandler()
Default constructor.
Method Summary
voiddestroy()
The destroy method indicates the end of lifecycle for a Handler instance.
abstract QName[]getHeaders()
Gets the header blocks processed by this Handler instance.
booleanhandleFault(MessageContext context)
The handleFault method processes the SOAP faults based on the SOAP message processing model.
booleanhandleRequest(MessageContext context)
The handleRequest method processes the request SOAP message.
booleanhandleResponse(MessageContext context)
The handleResponse method processes the response message.
voidinit(HandlerInfo config)
The init method to enable the Handler instance to initialize itself.

GenericHandler

protected GenericHandler()
Default constructor.

Method Detail

destroy

public void destroy()
The destroy method indicates the end of lifecycle for a Handler instance. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

getHeaders

public abstract QName[] getHeaders()
Gets the header blocks processed by this Handler instance.

Returns: Array of QNames of header blocks processed by this handler instance. QName is the qualified name of the outermost element of the Header block.

handleFault

public boolean handleFault(MessageContext context)
The handleFault method processes the SOAP faults based on the SOAP message processing model. The default implementation of this method returns true. This indicates that the handler chain should continue processing of the SOAP fault. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Parameters: context the message context

Returns: true/false

handleRequest

public boolean handleRequest(MessageContext context)
The handleRequest method processes the request SOAP message. The default implementation of this method returns true. This indicates that the handler chain should continue processing of the request SOAP message. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Parameters: context the message context

Returns: true/false

handleResponse

public boolean handleResponse(MessageContext context)
The handleResponse method processes the response message. The default implementation of this method returns true. This indicates that the handler chain should continue processing of the response SOAP message. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Parameters: context the message context

Returns: true/false

init

public void init(HandlerInfo config)
The init method to enable the Handler instance to initialize itself. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Parameters: config handler configuration
