To answer this question, we need to understand the difference between the methods getParameterValue() and getParameterValues() in the ServletRequest interface.

Option A) getParameterValue() - This option is incorrect because the getParameterValue() method returns a single value associated with a parameter. It does not return multiple values.

Option B) getParameters() - This option is incorrect because the getParameters() method returns a Map object containing all parameter names and their corresponding values. It does not specifically return multiple values associated with a single parameter.

Option C) getParamValues() - This option is incorrect because the getParamValues() method does not exist in the ServletRequest interface.

Option D) getParameterValues() - This option is correct because the getParameterValues() method returns an array of String objects containing all values associated with a parameter. If multiple values are associated with a parameter, this method allows you to retrieve all of them.

Therefore, the correct answer is option D. The getParameterValues() method returns more than one value associated with a parameter.

To answer this question, we need to understand the different types of enterprise beans in Java EE.

Option A) BMP Entity bean - This option is incorrect because BMP (Bean-Managed Persistence) Entity beans do have a client view interface.

Option B) CMP Entity bean - This option is incorrect because CMP (Container-Managed Persistence) Entity beans also have a client view interface.

Option C) Stateful Session bean - This option is incorrect because Stateful Session beans have a client view interface.

Option D) Stateless Session bean - This option is incorrect because Stateless Session beans also have a client view interface.

Option E) Message Driven Bean - This option is correct because Message Driven Beans are the only type of enterprise beans that can be defined without any client view interfaces. Message Driven Beans are used for asynchronous processing of messages received from a messaging system.

Therefore, the correct answer is option E) Message Driven Bean.

To answer this question, you need to understand the SessionFacade pattern and its advantages. Let's go through each option to understand why it is correct or incorrect:

Option A) Hides model complexity from the client - This option is correct. One of the advantages of using the SessionFacade pattern is that it hides the complexity of the underlying model from the client. The client only needs to interact with the simplified interface provided by the SessionFacade.

Option B) Reduces network traffic - This option is correct. Another advantage of using the SessionFacade pattern is that it can help reduce network traffic. By encapsulating multiple operations into a single method call, the SessionFacade can minimize the number of network requests required.

Option C) Provides a simple interface to the client - This option is correct. The SessionFacade pattern provides a simple interface to the client. Instead of having to interact with multiple components or services directly, the client can use the SessionFacade as a single entry point for its operations.

Option D) Enables the client to control transactions - This option is incorrect. The SessionFacade pattern does not enable the client to control transactions directly. Instead, it encapsulates the transaction management logic within the SessionFacade itself. The client interacts with the SessionFacade, but it does not have control over the transaction boundaries.

The correct answer is D) Enables the client to control transactions. This option is incorrect because the SessionFacade pattern does not provide this advantage.

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) True - This option is correct. In Java, static dispatch refers to the binding of a method call to its declaration at compile-time, based on the static type of the reference variable. This means that the method to be called is determined at compile-time and does not change at runtime.

Option B) False - This option is incorrect. Static dispatch does exist in Java.

The correct answer is A) True. This option is correct because static dispatch is a concept in Java where the method to be called is determined at compile-time based on the static type of the reference variable.
