Java Web Development (JSP/Servlets) Services |
| Java became popular on the Internet due to the small java applets in 1995. Java applets provided great looking
web sites. Java became pouplar due to its cross platform support.
Java Appliction runs same on Windows as on Linux/Unix/Mac. JSP and Java Servlets are used for server side programming to create dynamic pages which change with every request.
We have JSP/ Servlet programmers/developers. We can provide all kind of java web development services.

- Essential JVM Tools for Garbage Collection Debugging
Java garbage collection is a boon to programmers, but it can cause headaches in production. Poorly-tuned GC is extremely resource-hungry.
Tuning and troubleshooting GC is therefore an important skill. How do you obtain information on how GC is performing? What tools can you use to identify bottlenecks and inefficiencies?
- Advanced Java Garbage Collection Concepts: Weak References, Finalization, and Memory Leaks
The WeakReference() class in Java is often touted as being the answer to memory leaks. However, weak references on their own are not necessarily the answer.
Memory leaks are one of the hardest issues to diagnose. This article looks at a scenario where using weak references in conjunction with an object’s finalize() method can result in a memory leak.
- Distributed Rate Limiting in Java: A Deep Dive into Bucket4j + PostgreSQL
Important note: There are implementation details for the integration between PostgreSQL and the bucket4j library, specifically for version 8.14.0. The post's author is not responsible for future changes, but I'm 90% sure that it will be accurate for a long time.

- How to Test Multi-Threaded and Concurrent Java
Testing multi-threaded, concurrent Java code is difficult because each test run only captures one possible thread interleaving, and those interleavings are non-deterministic.
To address this, I created the open-source tool VMLens. VMLens allows you to test concurrent Java code in a deterministic and reproducible way by executing all possible thread interleavings.
- From Java 8 to Java 21: How the Evolution Changed My Developer Workflow
As a Java developer who spent years working with Java 8, I was comfortable with the stability and functionality it provided — lambda expressions, Streams and the java.time API felt like revolutionary improvements when they first arrived. But like many others, I stuck with Java 8 for years, not seeing the need to move on. That was, until I had the chance to work with Java 17 and eventually Java 21. In this post, I reflect on the features that truly changed the way I code and why it’s worth upgrading from Java 8 to Java 21.
Why I Stuck With Java 8 for So Long
I stuck with Java 8 for a long time because it just worked. It was stable, widely adopted and most importantly, it met the needs of enterprise projects. Newer versions came out, but transitioning wasn't always worth the effort — until my personal project pushed me to try something different. As I joined a team using Java 17+ and started working with Java 21 in real-world projects, I began to see just how much had changed.
