Fix memory leaks in Java production applications in 5 steps

Adding more memory to your JVMs (Java Virtual Machines) might be a temporary solution to fixing memory leaks in Java applications, but it for sure won’t fix the root cause of the issue. Instead of crashing once per day it may just crash every other day. “Preventive” restarts are also just another desperate measure to minimize downtime – but – let’s be frank: this is not how production issues should be solved. Based on a real life scenario we recently went through we discuss the 5 Steps it takes from analyzing to fixing memory issues in production environments.

Integrating WebSockets and JMS with CDI Events in Java EE 7

WebSocket is the new kid on the block when you think about Web Development these days. And it is expected that you want to integrate it with whatever is available in your hands. Java EE 7 is coming with cool things beyond this, for example JMS 2.0. And then you wonder: how can I send asynchronous messages to all WebSocket sessions connected to my website? Server push; no polling: for real!

It took me 10 years to launch eXo Platform 4.0!

Today we're launching the Express and Community Editions of eXo Platform 4.0: The Open Source Enterprise Social Platform. After 10 years, I feel like this is the first product we’ve launched that has this level of fit and finish: something that has never been accomplished before in the open source world. I even think it is among the most beautiful enterprise software ever launched.

jORM is a lightweight Java ORM

Java Training courses from Seer Computing

Why Java?

Java is the critical coding skill for any Developer wishing to grow their commercial potential and keep a competitive edge in today's market. Fast becoming the standard programming language used across all kinds of enterprise, it is a vast and rich system. That's why having more than a cursory knowledge of the concepts of Java programming is essential for the serious IT professional.

Need a solid grounding in the Java toolset?

Hands-on experience is vital with such a functionally rich product, that's why at a Seer training course, delegates spend over 50% of their specialist IT training course using Java in practical and stimulating exercises supported by our experienced trainers. Each topic is introduced and developed with working code, written by our own consultants. Download the index of the courses here to review their structure and depth.

Come to Seer for best in class Java training

We have tailored our three Java training courses to maximise the learning experience for anyone wishing to learn more about Java. Our best in class IT training courses are geared towards those who are new to the world of Java programming, for those with entry-level knowledge, and for those with a reasonable knowledge of the concepts of Java programming.

All our courses can be run as onsite training or as public training courses. Our popular onsite training means we bring everything to you. We take charge of the quick set-up, delivering hands-on courses with all the relevant training materials at your chosen place of work.

Onsite training can be the least disruptive to a busy schedule and can be far more cost-effective than leaning on budgets for extra travel costs for a group of delegates. We believe that any corporate training should be at an all-inclusive price, so ours is. There's no hidden extras, click here to contact us about setting up some valuable onsite training.

When there's only yourself or a colleague to be trained, you might find it's more cost-effective to attend one of our public training courses which take place across the year at all major UK and Irish cities from London to Edinburgh, Birmingham to Dublin. Click here to find your next public IT training course.

Fundamentals of Java Course

Our Fundamentals of Java course covers all aspects of the Java product, from simple Java applications run on the DOS command line to Java Swing applications for more advanced GUI capabilities, both as an application and as a Java Applet embedded in HTML.

This 5-day Java training course comes with a complete set of working examples, plenty of practical exercises that work through the Java language as well as a set of in-depth manuals spanning over 950 pages.

Topics are covered in an interesting way that's easy to read, and easy to refer back to when you need a refresh. Click here for information on how to book your course as a public training course, or even better, onsite training at your chosen location.

Java Programming Course

The 3-day Java Programming course splits learning Java into two distinct product areas - Java Programming and OOPs (Object Orientated Programming). The first part of the Java training course covers the structure, concepts and theories behind Java, looking at basic Applications, handling variables and dates. The second parts enables delegates to learn about OOP concepts.

This 3-day course equips delegates with a sound intermediate knowledge of Java Programming and we recommend it should be followed by a future course in Java Swing Development to fully optimise all areas of knowledge.

Java Swing Development

Java Swing Development is the suite of classes and methods which allows a Developer to produce professional standard GUI front ends, either as an Application or an Applet. Its predecessor was called AWT and while Swing more or less replaces it, the course does cover some of the classes which still use AWT.

This intensive 3-day Java training course is recommended for those who have already attended our Java Programming training course or for established Java programmers wanting to learn more about Java Swing.

The Future of Java Training at Seer

We are developing three new courses to complement our popular Java training courses. Look out soon for Working with Java and Oracle, JavaScript and Advanced Java Training.

Also coming soon from Seer is the JDeveloper course, which will lead delegates through Oracle's generation of Java modules. Contact us below for more information on release dates and availability for our latest courses.
