A tag in JSP that controls the JSP engine and instructs it on how to process the page. It doesn't generate any code for the Servlet.

A tag that inserts Java code into the generated Servlet code, outside of any method.

A tag that displays the value of an expression in string format.

A comment that is only processed on the server and not sent to the client. It is used for documentation.

A comment that is sent to the client and may be visible in the browser source code.

JSPs, or Java Server Pages, are a technology for generating dynamic HTTP content (web pages). They are essentially HTML pages with embedded Java code.

JSPs allow web developers to create both static and dynamic web pages by combining HTML with dynamic content generated through Java code.

JSP is an extension of the Servlet technology. It builds upon the Servlet framework, providing a more convenient way to generate web pages.

JSP offers several benefits including separation of content and logic, simplified web development, reusability of components, automatic deployment, easier authoring, and platform independence.

While Servlets are capable, JSPs make it easier to manage HTML, especially in terms of writing, reading, and maintaining it, making it a more efficient choice for web development.

Embedded Java code within a JSP page provides access to server-side data and allows for the implementation of business logic within the HTML structure.

Static content is fixed and remains unchanged, while dynamic content changes based on user interactions or server-side information, making the web page interactive.

Retrieving data from a bean using its properties in EL. Example: ${myBook.price} gets the price property value from the myBook bean.

Accessing data from collections (lists, arrays, maps) in EL. Example: ${myList[3]} returns the element at index 3 in the myList.

Evaluating a condition and returning a specific value based on the result. Syntax: ${test?Opt1, Opt2}. If test is true, Opt1 is returned. If test is false, Opt2 is returned.

Expression Language (EL) can only retrieve data, it cannot modify or set data. It's designed for reading information.

Accessing deeply nested properties in objects using a hierarchical notation. Example: ${student.address.state} accesses the 'state' property of the 'address' object, which is a property of the 'student' object.

Java code snippets embedded within a JSP page. Scriplets allow you to add dynamic behavior to webpages.

The jsp:setProperty action is used to set the value of a bean's property. It can be triggered by an input parameter name, a defined value, or the matching request parameter-property name pair.

Defines the ID of the bean in the action tag. This ID identifies the bean you want to modify.

Specifies the specific property within the bean that you want to set a value for.

Determines the value to be assigned to the specified bean property. This value can be a literal string, a variable, or an expression.

Associates the bean property with an input parameter from the request form or query string.

Used with the "property" attribute. This wildcard means that all properties in the bean will be mapped to request parameters with matching names.

You cannot use both the "value" and "param" attributes at the same time. You can use neither to indicate property-parameter name matching.

JSP stands for JavaServer Pages, a server-side programming technology for creating dynamic web pages. It's built on top of Servlet technology, meaning each JSP page gets translated into a Java Servlet during runtime.

JSP relies on a Servlet container like Tomcat to execute. When a web server receives a JSP request, it hands it off to the container's JSP engine, which translates the JSP into a Java Servlet, compiles it, and then runs the resulting code to generate the web page.

JSP focuses on data presentation. It dynamically renders HTML output using data from various sources like JavaBeans, Servlets, and databases. The actual business logic and computation are handled by other web components.

JSP's tag library is extensible, allowing developers to create their own reusable custom tags. These tags can encapsulate complex logic or UI elements, making JSP code more modular and maintainable.

EL is a powerful language introduced in JSP 2.0 that simplifies accessing data within JSPs. EL expressions are lightweight and can retrieve data from JavaBeans, request attributes, and more, making JSP coding easier and more efficient.

Implicit server objects are pre-defined objects accessible within JSPs. Examples include 'request' (for client data), 'response' (for sending output), and 'session' (for managing user data). These objects provide the framework for interacting with the web environment.

When a request is made to a JSP page, the JSP engine checks if the page has been modified since its last access. If it has, the engine translates the JSP into a Java Servlet, compiles it, and then executes it. The results are sent back to the client.

A reusable component written in Java, designed to encapsulate specific functionality within a JSP page. They enhance code reusability, readability, and maintenance.

It's the entry point for a custom tag. It's called by the JSP container when the starting tag of the custom tag is encountered. This method is used to perform actions such as printing content or initiating specific operations within the JSP.

When a custom tag's 'doStartTag()' method returns 'SKIP_BODY' it indicates that no content within the body of the tag needs to be evaluated or processed. The JSP container skips the processing of the tag's body content.

It's a configuration file that defines custom tags and maps them to corresponding Java classes (tag handler classes), managing the relationship between tag names and their implementations.

It acts as a namespace within the JSP page, allowing you to distinguish between various custom tags from different libraries. It prefixes the custom tag name and helps avoid naming conflicts.

The 'myLib.tld' file defines the tag and its attributes, while the corresponding Java class defines the logic for that tag. The Java class acts as the tag handler, handling the tag's processing and behavior.

When a custom tag is encountered in a JSP, the JSP container reads the taglib directive and its attributes, locates the corresponding tag handler in the specified 'myLib.tld' file, and invokes it's 'doStartTag()' method, followed by any subsequent methods (like 'doEndTag()').

The container uses the information from the taglib directive (including the prefix and tld location), finds the matching custom tag definition in the 'myLib.tld' file, maps this definition to the corresponding Java class (tag handler), instantiates the tag handler, and finally invokes its 'doStartTag()' method.
