During the translation phase each type of data in a JSP page is treated differently. Static data is transformed into code that will emit the data into the response stream. JSP elements are treated as follows: Directives are used to control how the web container translates and executes the JSP page.
Which JSP life cycle is in the correct order?
Which one is the correct order of phases in JSP life cycle? Explanation: The correct order is Compilation, Initialization, Execution, Cleanup.
What is servlet life cycle?
A servlet life cycle can be defined as the entire process from its creation till the destruction. The following are the paths followed by a servlet. The servlet is initialized by calling the init() method. The servlet calls service() method to process a client’s request.
How many stages are there in JSP life cycle?
Let’s learn different phases of JSP Life Cycle
Compilation process of JSP page involves three steps: Parsing of JSP. Turning JSP into servlet. Compiling the servlet.
How is JSP compiled?
The JSP engine compiles the servlet into an executable class and forwards the original request to a servlet engine. A part of the web server called the servlet engine loads the Servlet class and executes it. During execution, the servlet produces an output in HTML format.
Is JSP compiled or interpreted?
At run time, the JSP code is interpreted by the JSP compiler, which parses out all the special features in the JSP code and translates them to Java code. The Java class created from each JSP implements Servlet .
What are advantages of JSP?
