To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) It allows the JSP to access middleware - This option is incorrect because JavaBeans itself does not directly enable JSP to access middleware. However, JavaBeans can be used in conjunction with other technologies to access middleware.
Option B) It creates a cleaner role separation between the web-production team and the software development team, so that the web-production team can focus on presentation markup, while the software team can focus on building reusable software components for helping - This option is correct. JavaBeans provide a way to separate business logic from presentation markup within the JSP environment. This separation allows the web-production team to focus on the presentation markup, while the software development team can focus on building reusable software components (JavaBeans) that handle the business logic.
Option C) It provides a dynamic markup environment, such that JavaBeans are integrated seamlessly with the template presentation content, in order to create the dynamic display for the client - This option is incorrect. While JavaBeans can be used to create a dynamic display for the client, it does not specifically provide a dynamic markup environment. JSP itself provides the dynamic markup environment by allowing the integration of JavaBeans with the template presentation content.
Option D) It provides the developer with full access to the Java 2 Platform Enterprise Edition (J2EE), which is unavailable from outside the JavaBean environment - This option is incorrect. JavaBeans do not provide exclusive access to the Java 2 Platform Enterprise Edition (J2EE). J2EE is a separate platform that JavaBeans can be used with, but it is not limited to JavaBeans.
The correct answer is B. It creates a cleaner role separation between the web-production team and the software development team, so that the web-production team can focus on presentation markup, while the software team can focus on building reusable software components for helping. This option highlights one of the benefits of using JavaBeans to separate business logic from presentation markup within the JSP environment.
