JSP technology: do JavaServer Pages (JSP) enable creation of dynamic web pages using HTML mixed with Java code and tags? Provide the most accurate evaluation.

Difficulty: Easy

Correct Answer: Valid (JSPs allow dynamic pages using HTML plus Java/JSP tags)

Explanation:


Introduction / Context:
JavaServer Pages (JSP) is a server-side technology that compiles to servlets, enabling dynamic content generation in web applications. This question tests a foundational understanding of what JSP is intended to do.


Given Data / Assumptions:

  • JSP supports HTML markup combined with JSP tags and Expression Language (EL).
  • JSPs are executed on the server within a servlet container.
  • Output is dynamic HTML (or other text formats) sent to the browser.


Concept / Approach:
A JSP page is translated to a servlet by the container. It may contain directives, scriptlets (legacy), tag libraries (JSTL), and EL to bind to Java objects. This architecture enables creation of dynamic web pages that mix presentation with server-side logic (modern best practice favors EL and tag libraries rather than scriptlets).


Step-by-Step Solution:

Client requests a .jsp resource.Container compiles the JSP to a servlet on first use.Servlet executes Java logic and produces dynamic HTML.Browser receives rendered content independent of server platform.


Verification / Alternative check:
Inspect the work directory of a servlet container (for example, Tomcat) to see generated servlet code from JSPs.


Why Other Options Are Wrong:

  • JSPs are not limited to static HTML; they are expressly for dynamic content.
  • OS, ODBC, and browser versions are unrelated to core JSP capability.


Common Pitfalls:
Overusing scriptlets instead of EL or tag libraries; mixing heavy business logic directly into JSPs rather than controllers.


Final Answer:
Valid (JSPs allow dynamic pages using HTML plus Java/JSP tags)
