Jens O.
Last position:
Frontend Developer at Volkswagen Financial Services AG
Cross-brand design system
Focus: Analysis of the causes of recurring layout deviations in design system components. The cause was the integration of visual regression tests (BackstopJS) into the build and approval process: deviations were not blocked, and reference images were replaced without approval.
Recommendations for a controlled workflow with mandatory approval and test results as a prerequisite for merging. Contributed to the successor system based on Lit/Web Components.
Technologies: Lit, Web Components, SCSS, Gulp, BackstopJS, GitHub Enterprise, JFrog Artifactory

About the technology
JSP view logic
JSTL, the JavaServer Pages Standard Tag Library, adds reusable tags for conditions, iteration, formatting and resource access in JSP views. It keeps common presentation logic out of scriptlets and works closely with Expression Language (EL) to read scoped data from Java web applications.
Core tag libraries
The core library handles flow control and collection output. Formatting supports dates, numbers and messages, while SQL and XML libraries exist for narrow legacy scenarios. Strong specialists choose the right tags and avoid placing persistence or complex business rules in a view.
Java web ecosystem
JSTL projects commonly involve JSP, EL, Java servlets, JavaBeans and application servers within Java EE or Jakarta EE environments. Specialists may also work with Maven, Gradle, tag files, custom tags, servlet filters, session scopes and template layouts. They understand the effect of namespace and dependency changes when applications move toward Jakarta EE.
Typical project work
- Replace JSP scriptlets with readable JSTL and EL expressions
- Extend an existing tag library without breaking page behavior
- Migrate views between Java EE and Jakarta EE dependencies
- Diagnose escaping, scope, encoding and conditional-rendering issues
- Connect JSP pages cleanly to servlet or Spring MVC controllers
When specialists help
Companies bring in freelance JSTL expertise when a mature portal needs safe change without a full rewrite. This is common in regulated and enterprise environments in Germany, where long-running Java applications may still serve customer, employee or back-office workflows. Remote work is practical when repository access, environments and release ownership are clearly arranged.
Quality signals
A strong professional traces data from controller to scope to rendered markup and tests both empty and populated states. They distinguish JSTL problems from EL, servlet, dependency or browser issues, and verify escaping against security requirements. Clear migration notes, focused tests and restrained use of custom tags are signs of maintainable work.
Frequently asked questions
Quick answers to the questions that come up most around JSTL.
JSTL is used in JSP pages for conditions, loops, formatting, message lookup and other recurring view tasks. It works with Expression Language so pages can render application data without embedding Java scriptlets.
JSTL offers a tag-based approach designed for JSP, while Thymeleaf uses HTML-oriented templates that can be easier to preview outside a running application. Compared with scriptlets, JSTL usually produces clearer and more consistent view code, but it may be less attractive for a new application choosing a modern template stack.
A capable JSTL specialist should understand JSP, Expression Language, servlets, Java web scopes and dependency management. Knowledge of Spring MVC, Java EE or Jakarta EE, application servers, HTML, CSS and web security is also useful for diagnosing issues beyond the tag itself.
The right level depends on whether the work is a small view change, a library migration or a wider JSP modernization. For JSTL, look for someone who can explain tag evaluation, scope resolution, escaping and the application's servlet or framework lifecycle rather than relying only on surface syntax.
Yes, JSTL work is often suitable for remote collaboration when the specialist can access the codebase, test environments and deployment process. For German teams, agree early on working language, review routines, data-access rules and any need for occasional on-site workshops.
Keeping JSTL can be sensible when JSP pages are stable, well tested and tightly integrated with a mature Java application. Replacement deserves consideration when the view layer is hard to test, heavily scripted, difficult to secure or blocking a planned move to another template approach.
Ask a JSTL professional to walk through how data reaches a page, how null and empty values behave, and how output is escaped. Review whether the change separates presentation from business logic, handles localization correctly and includes tests for important rendering paths.
A JSTL migration can expose mismatched library namespaces, missing tag dependencies, changed EL behavior or differences between Java EE and Jakarta EE runtimes. A careful specialist checks build files, server compatibility, page directives, encoding and custom tags before changing application logic.
