Why Do We Need Code Formatters?
Badly indented or poorly spaced code is hard to read – and even harder to maintain. A code formatter means that you give it a bunch of raw minified unformatted code, and a code formatter will transform it into a well structured standard way of writing code. This process includes ensuring proper indentation, spacing, and line breaks to enhance readability.
- For Example:
- JSON Code Formatter Viewing and Debuging machine readable data structures now is getting easier.
- HTML Code Formatter & CSS Code Formatter enhance web code readability, especially when copied from other sources or compressed files.
- Javascript Code Formatter & Python Code Formatter Clean up your scripts according to best practice so they are clean and production ready.
- SQL Code Formatter structures your queries clearly, even when dealing with complex joins and subqueries.
- XML Code Formatter will make sure your data and configuration are easy to read and free of errors.
- Java Code Formatter, C Code Formatter, and Php Code Formatter help maintain consistent code across large-scale projects.
Computers don't care how your code appears. As long as the syntax is fine, it will run it no matter if there are spaces, tabs or newlines at the end of the line.
This is why tools like JSP code formatters or beautifiers are mainly used for improving code readability and maintaining consistency—helpful for developers, but ignored by the machine.
Improve Readability
Clean code is easier to read and comprehend. This is particularly important in large teams where developers are commonly reviewing and editing each other's code.
Save Time
Code that looks nice is easier to read and understand. This is even more crucial while working in the large teams when developers often check on each other code changes.
Facilitate Collaboration
Code has different styles if written by different developers. A formatter helps to prevent conflicts and keep things peaceful and misunderstandings.

JSP Code Formatter – Beautify JavaServer Pages for Web Development
1. What is JSP?
JSP (JavaServer Pages) is a server-side web technology that allows developers to create dynamic, Java-powered web applications. It enables the embedding of Java code directly into HTML pages using special tags, making it easy to combine presentation and logic in a single file. JSP runs on a Java-enabled web server and is compiled into servlets, which are Java programs that handle requests and generate responses.
Primarily used in Java EE environments, JSP simplifies the development of server-rendered web pages by allowing developers to use familiar HTML syntax while leveraging the power of Java. It supports tag libraries, JavaBeans integration, session management, and expression language (EL) for clean and maintainable dynamic content generation.
2. History of JSP
JSP was introduced by Sun Microsystems in 1999 as part of the Java 2 Platform, Enterprise Edition (J2EE). Its goal was to provide a simpler alternative to pure servlets for building dynamic web pages, allowing developers to embed Java code within HTML similar to how PHP or ASP worked at the time.
Over the years, JSP evolved to support custom tag libraries (JSTL), JavaBeans, and more robust frameworks like Struts and Spring MVC. With the rise of newer frontend technologies and REST APIs, JSP is less commonly used for modern applications, but it remains important in legacy enterprise systems and Java-based intranet applications.
3. JSP Syntax Example
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<Head><meta charSet="UTF-8" /><title>Welcome Page</title></head>
<body>
<h1>Welcome, <%= request.getParameter("user") %>!</h1>
</body>
</html>This simple JSP page reads a user parameter from the HTTP request and displays it dynamically within an HTML page. Mixing Java logic with HTML like this can quickly get messy in larger files—making a JSP code formatter essential for keeping the structure clean and readable.
4. Why Use a JSP Code Formatter?
JSP files often contain a blend of Java code, HTML, JSTL tags, and EL expressions. Maintaining consistent formatting across these layers is crucial for readability, debugging, and team collaboration.
- Improves readability: Clear formatting makes it easier to distinguish between logic and markup.
- Reduces errors: Helps prevent misplaced tags or syntax issues, especially in nested structures.
- Maintains consistency: Follows a common style for all JSP pages in a project.
- Enhances productivity: Auto-formatted files are faster to update and debug.
- Supports maintainability: Especially important for legacy enterprise apps with large JSP files.
Our JSP code formatter beautifies your files while preserving Java logic, HTML structure, and tag libraries.
5. Advantages of JSP
- Java integration: Direct access to Java APIs, objects, and classes.
- Server-side processing: Enables dynamic content generation before sending HTML to the client.
- Tag libraries support: JSTL and custom tags promote reusable code and cleaner logic separation.
- Session and request management: Easily manage user sessions, cookies, and request parameters.
- Well-supported in Java EE: Works seamlessly with Servlets, EJB, JDBC, and JavaBeans.
6. Disadvantages of JSP
- Mixing logic and presentation: Embedding Java directly in HTML violates MVC principles.
- Verbose syntax: JSP code can become complex and hard to debug in larger applications.
- Harder to maintain: Complex tag nesting and business logic in views can lead to bloated files.
- Outdated for modern apps: REST APIs with frontend frameworks like React or Angular are preferred now.
- Requires server compilation: JSP must be compiled into servlets before execution.
7. Real-World Use Cases for JSP
- Enterprise intranet applications: Government, banking, and corporate tools often use JSP.
- University systems: Admin portals, course registration, and student dashboards.
- Content management systems: JSP-based CMSs for Java web platforms.
- Legacy Java EE systems: Many still use JSP as a frontend layer for EJB-based backends.
- E-commerce platforms: Some early Java shopping cart systems used JSP to render product pages dynamically.
8. JSP vs Other Server Technologies
- vs Servlets: JSP simplifies writing HTML-heavy responses; Servlets are better for business logic.
- vs PHP: JSP is compiled and Java-based; PHP is interpreted and more loosely typed.
- vs ASP.NET: ASP.NET integrates with the .NET ecosystem; JSP integrates with Java EE stack.
- vs Thymeleaf: Thymeleaf offers cleaner templates with less embedded Java logic.
9. Why JSP Code formatter important
Given JSP’s mixed syntax, files often contain:
- HTML markup
- Java code (scriptlets or expressions)
- JSTL tags (forEach, if, choose)
Without proper indentation and tag alignment, these files can quickly become unreadable. Our JSP formatter handles these complexities to keep your codebase maintainable and error-free.
10. JSP Formatting Best Practices
- Avoid scriptlets; use JSTL and EL whenever possible.
- Group related sections (imports, headers, logic) logically.
- Indent nested tags and loops consistently.
- Use whitespace to separate HTML and logic blocks.
- Close all tags properly; improper nesting causes runtime errors.
- Separate business logic into JavaBeans or Servlets—keep JSP for view only.
11. Tools That Support JSP Formatting
- Apache Tomcat: Popular JSP servlet container.
- Eclipse IDE: Supports JSP editing with formatting plugins.
- IntelliJ IDEA: JSP support with smart formatting and syntax highlighting.
- NetBeans: Built-in JSP editor and formatter.
- Prettier Plugins: Some Prettier extensions now handle mixed HTML + JSP content.
- Online JSP Formatter: Format JSP instantly in-browser.
12. The Future of JSP
While JSP has declined in popularity due to modern frontend frameworks and API-based architecture, it still holds value in maintaining and updating enterprise systems that were built over the past two decades. Migration away from JSP can be expensive and time-consuming, making formatter tools vital to help teams work with existing code efficiently.
Newer template engines like Thymeleaf and JSF have taken the spotlight in the Java ecosystem, but JSP remains supported and used where legacy compatibility is needed.
13. Conclusion
JSP played a significant role in early dynamic web development and continues to power enterprise-grade applications. However, its hybrid syntax of HTML, Java, and tag libraries makes proper formatting a necessity—not an option.
The JSP code formatter helps developers structure their pages neatly, debug faster, and collaborate effectively—even in large or legacy Java applications. Whether you're maintaining an old system or teaching JSP concepts to students, clean formatting is a must.
Frequently Asked Questions
