SAAJ APIs.
Which elements of the HTTP messages exchanged in a J2EE Web service interaction can be
accessed using these APIs?
A. the SOAP header elements

Question: 218
Given:
1. public boolean handleRequest(MessageContext context){
2. try{
3. SOAPMessageContext soapCntxt = (SOAPMessageContext)context;
4. SOAPMessage message = soapCntxt.getMessage();
5. message.writeTo(logStream);
6. }catch(javax.xml.soap.SOAPException se){
7. throw new javax.xml.rpc.JAXRPCException(se);
8. }
9. }
The handleRequest method (lines 1-9) is implemented by a JAX-RPC handler.
Given that the logStream is a reference to some type of java.io.OutputStream, which two are
true? (Choose two.)
A. If the handler is associated with a JAX-RPC generated stub, it will write outgoing SOAP
messages to the logStream object.

Question: 219
Given:
1. public boolean handleRequest(MessageContext context){
2. try{
3. SOAPMessageContext soapCntxt = (SOAPMessageContext)context;
4. SOAPMessage message = soapCntxt.getMessage();
5. message.writeTo(logStream);

7. throw new javax.xml.rpc.JAXRPCException(se);
8. }
9. }
The handleRequest method (lines 1-9) is implemented by a JAX-RPC handler used for logging.
Given that the method encounters an error and throws a JAXRPCException, which is true?
If the method is implemented by a client-side handler, it will cause a SOAP fault to be generated.
If the method is implemented by a server-side handler, it will cause a SOAP fault to be generated.
If the method is implemented by a client-side handler, the message will continue to be processed
by the handler chain.
If the method is implemented by a server-side handler, the message will continue to be
processed by the handler chain.
Answer : B
Question: 220
Given:
<message name="InvalidItemID">

<output message="sws:getHighBidResponse"/>
<fault name="InvalidItemID" message="sws:InvalidItemID"/>
</operation>
</portType>
Which endpoint method declaration is generated by this service?
A. public float getHighBid(String itemID);
B. public float getHighBid(String itemID)
throws InvalidItemID;
C. public float getHighBid(String itemID)

Question: 221
A JAX-RPC client is using a stub to connect to a service. The stub implementation supports only
the standard properties supported in the JAX-RPC Stub interface. The client must set the
endpoint address property on the stub.
Given:
stub._setProperty("HTTPLOCATION","http://localhost:8080/services/mySvc");
What is the result?
A.
B.
C.
D.
The application throws an application-specific exception.
The application throws a java.rmi.RemoteException.
The application throws a javax.xml.rpc.JAXRPCException.
The value "http://localhost:8080/services/mySvc" is assigned to the "HTTPLOCATION"
property.
Answer : C
Question: 222
A client sends a required SOAP header in a SOAP message. The server-side process

C. MustUnderstand
D. VersionMismatch
Answer : A
Question: 223
Which describes the handling of application exceptions thrown by a JAX-RPC service endpoint?

C. Application exceptions are always propagated to JAX-RPC clients as RemoteExceptions.
D. Application exceptions are always propagated to JAX-RPC clients as SOAPFaultExceptions.
Answer : A
Question: 224
