Whats new in GlassFish 4.1? by C2B2


clip_image001GlassFish 4.1 was released a couple of months ago now, bringing with it a large number of welcome bug fixes and improvements. As the Payara Open Source project was born from it, it would be remiss of us not give all of you who maintain an interest in GlassFish a brief overview of some of the things that have changed or been updated since 4.0. Among these changes, the minimum JDK version required is now 7 Update 65, or 8 Update 20, so you'll need to update if you intend to use it with anything less; it likely just won't start otherwise!

Updated Platforms and Specifications

As you might expect from any major update to an application server (even if it is just a minor point release), and particularly since GlassFish still holds itself as the Java EE reference application server, there is now support for more recent platforms and Java EE specifications.

Java SE 8

Arguably the headline new feature, GlassFish 4.1 now supports Java SE 8, bringing it up to date with the latest Java specifications. This brings with it all of the new features available in Java 8, such as Lambda expressions, a brand new Date and Time API, and concurrent accumulator classes. There’s quite a stir around the introduction of Lambda expressions, and how it adds some functional programming “oomph” to the Java language.

GlassFish is here to stay. We heard it from the Oracle by C2B2

clip_image001We are at JavaOne 2014 and one of the key reasons for me to attend was to catch up on the future of GlassFish. So on Sunday I went along to the GlassFish community update at the Moscone Center to consult with the Oracle on the future of GlassFish.
The reason I go to JavaOne is to hear the definitive view on GlassFish and JavaEE futures from the people that make the decisions. There's no other conference you can say that about.
On the stand there were 4 Oracle guys who make the decisions on GlassFish.
John Clingan - Product Manager for JavaEE and GlassFish; Mike Lehman - Product Manager for Cloud Application Framework; Cameron Purdy - VP Development; Reza Rahman - Evangelist for JavaEE and GlassFish.
What I saw was that there is a roadmap for GlassFish out until JavaOne 2016 as JavaEE8 develops with GlassFish 5 being the reference implementation for JavaEE 8. GlassFish 5 will aim to be released as the final draft for JavaEE 8 hit the JCP.
Cameron spoke about GlassFish being a key Research and Development platform with much of the technology created in GlassFish to support the JavaEE specifications finding its way into WebLogic with GlassFish having a key role in the evolution of JavaEE far into the future. Many of the key JavaEE specification developers are working on GlassFish as part of their JSR work and that is a huge investment.
John reiterated that Quality, stability and security are still important. The team continue to work to ensure that GlassFish passes all the JSR Compatibility Test Suites and any issues will be fixed. In fact the key priorities for the recent 4.1 release were Java 8 support, stability and quality. Also much of the work invested into GlassFish for JavaEE 8 support will be shareable with WebLogic.

A Strong GlassFish by C2B2

Last November after the announcement by Oracle that no future release beyond the 3.x version of GlassFish would have support from Oracle there were a lot of doom and gloom articles about GlassFish. I tried to put my view that this probably wasn't the end of GlassFish but time would tell.


Why we need a Strong GlassFish
As the founder of a company that is vendor independent. I think it is imperative for the Java EE community that there is a strong vibrant GlassFish server. Having GlassFish out there as a viable production open source Java EE server drives competition. Competition drives innovation in competing products. Competition drives quality in competing products. Competition drives adoption through visibility and choice. If GlassFish fades then I'm afraid that the whole of Java EE fades. There will be no competitive incentive to drive innovation in WildFly, although I'm sure the RedHat engineers wouldn't consciously drive down innovation and quality but competition naturally keeps them lean, mean and fast. If GlassFish in the future fails to deliver a good out of the box experience for Java EE 8 and beyond due to poor quality or poor performance then future Java EE adoption as a whole is threatened. This threatens Oracle WebLogic, RedHat JBoss EAP, IBM WebSphere sales as where are the developers to choose the big beasts for production?

Optimism for the Future

Over 6 months have passed and I've been trying to take stock of where we are. I've recently hosted a community Community Q&A session with Reza Rahman and the London GlassFish User Group and organised a BOF at Devoxx UK with David Delabassee to get the community involved in what is happening with GlassFish. We've watched the code archives and started our own builds. Read the complete article here.

Getting the most out of WLDF Part 3: Notifications by C2B2

his blog directly follows on from part 2 on watches, so if you haven’t already read that then you should probably go and do that now. You can still create notifications without having any watches configured; you just won’t receive anything on them. In the last post, I had created two watches, one Server Log watch and one Collected Metrics watch. In this post, I will create notifications to work with these watches.

What are notifications?
WLDF notifications are nothing more than a particular configuration for alerting based on a condition. Think of them as channels of communication; unless something is sent down those channels, they will stay empty. The forms that these channels can take are:

  • SMTP Email
  • JMS Message
  • Diagnostic Image
  • JMX Notification
  • SNMP Trap

Which notification should I use?
There’s no right or wrong when it comes to choosing notification methods, but there is certainly annoying and non-annoying! Of the notification methods above, all but email are passive methods of alerting people concerned. The reason I classify them as passive is that you, as the end-user who wants to be notified, must perform some sort of action to consume that notification. For example, to consume JMS message data, you must use a JMS client and would likely process the data automatically, perhaps for graphing. Read the complete article here.

Getting the most out of WLDF Part 2: Watches by C2B2

In this post, I'll be looking at using watches in WLDF.
What is a watch? A watch, at its most basic, is simply a way to monitor one of three things:

  • MBeans
  • A server log
  • Instrumentation (event) data

To configure an instrumentation watch, you first need to know what instrumentation is, and how to instrument applications or servers, so we’ll put that to one side for now. A server log watch is exactly that - a watch to monitor the server log for anything you want! For example, all Critical severity log entries, entries which mention a particular server or particular log message IDs. An MBean watch relies on the Harvester to collect server runtime MBean metrics which does not need to be configured separately for your watch to work, but do bear in mind that the data gathered will not be archived unless you configure the Harvester properly:

Note:
If you define a watch rule to monitor an MBean (or MBean attributes) that the Harvester is not configured to harvest, the watch will work. The Harvester will "implicitly" harvest values to satisfy the requirements set in the defined watch rules. However, data harvested in this way (that is, implicitly for a watch) will not be archived. See Chapter 7, "Configuring the Harvester for Metric Collection," for more information about the Harvester.

How do I make a watch? I’ve already mentioned that Instrumentation watches require a little understanding of instrumentation first, so I won’t cover them here. If you’re already familiar with instrumentation, then configuring watches for your instrumented applications isn’t too tricky.

Step 1: Create a Diagnostic Module The first step in creating watches is always the same. In the Domain Structure pane, select “Diagnostic Modules” under the “Diagnostics” entry.

Select a diagnostic module if you’ve created one, or create a new one if not. Since creating a new module only requires you to name it (and provide an optional description), you’ll need to configure it once you’ve created it. The most important thing to do is to target it to the server you want to monitor. Read the complete article here.

Commercial GlassFish Support Is Back – Adam Bien’s Interview with Steve Millidge

Adam Bien: What is the relation between C2B2 and GlassFish?
Steve Millidge: We've had a long history helping customers to use GlassFish in production environments. In fact my first ever conference speech in California was at Sun's CommunityOne conference on Monitoring and Tuning GlassFish back in 2009, so we go back a long way. We were Sun partners back then, promoting GlassFish, and our now Oracle Gold Partners. We have a number of customers we support on GlassFish and we also run the London GlassFish User group. With the announcement from Oracle we are now gearing up our effort to build up the community of contributors on the core GlassFish source to ensure a good response when bugs and patches are needed.

AB: What is C2B2's Commercial GlassFish support? What will a customer get for the money?
SM: We provide 24/7 operational support to customers deploying GlassFish in production.  Read the complete article here.

Expert GlassFish Support

  • Do you run mission critical Applications on GlassFish?
  • Do you wish there was somebody to turn to if you had GlassFish performance, GlassFish scalability or GlassFish availability problems?
  • Do you find it difficult to recruit GlassFish operations specialists with deep knowledge?

C2B2 provide expert GlassFish support services 24/7 to customers running mission critical GlassFish applications. Our GlassFish engineers provide 2nd and 3rd line expertise as backup to your GlassFish operations team. Our expert GlassFish consultants can login to your servers and assist with triage, remedial action and root cause analysis of GlassFish problems rapidly reducing diagnosis and fix times.

When combined with a support subscription from Oracle we can liaise with Oracle to isolate test cases and get a GlassFish patch if that is the root cause. We can also liaise with your GlassFish development teams to identify application problems and suggest application fixes to increase GlassFish availability, GlassFish scalability and GlassFish performance.

WebLogic 12c Does WebSockets – Getting Started by C2B2

With the release of WebLogic 12.1.2 websocket support has come to WebLogic. In this blog post we'll show you how to write a simple websockets echo example just to get you started.
Unfortunately the api released with WebLogic is not the JEE7 JSR356 api, which I suspect will come when WebLogic gets JEE7 compliance. On the plus side it's a pretty simple api.
In this blog I'm using NetBeans 7.4 and I've started off by creating a basic web project and I've called it Echo.

Common WebLogic Problems by Steve Millidge

Oracle WebLogic was originally developed by BEA Systems, a company which was acquired by Oracle in 2008.

Since WebLogic had a much larger user base, Oracle quickly made their intentions to deprecate their own Oracle Application Server (OAS, sometimes referred to as OC4J, the J2EE container component) in favour of WebLogic as their primary offering.

C2B2 have worked with WebLogic since it was owned by BEA and have partnered with both BEA and Oracle. As partners, C2B2 have worked on a wide variety of customer engagements across Oracle’s full middleware portfolio.

Migration from OAS to WebLogic

Oracle Application Server has been deprecated for a number of years now, since Oracle have pushed forward with their plans to offer only WebLogic as their application server of choice. Even so, many businesses are still using OAS or OC4J to run their Java EE applications and are increasingly finding that they need to migrate to WebLogic to avoid being left with legacy infrastructure that they can no longer support effectively.

Fortunately, Oracle has anticipated the need for the process of migration to be as seamless as possible so, for their part, they have put a lot of effort into helping customers migrate their infrastructure. Unfortunately, however much work Oracle might do to help with this migration, there will always be problems or unforeseen circumstances due to the dependencies that applications might have on OC4J which change when moving to WebLogic.

Non-standard technology

A great advantage of buying from a company like Oracle is the ecosystem that you get along with the product. WebLogic, for example, has many other components built by Oracle to improve on the standard Java EE way of doing things. Problems can occur purely down to the vast amount of products and services that Oracle offer. Should you use WebLogic’s JMS implementation, Oracle’s Advanced Queuing (AQ) or Oracle Store-And-Forward for your messaging scenario? How do they differ? Is one better than another, or just better suited to certain applications? It’s clear to see that, although you can be sure that Oracle has a product or component to suit your scenario, it’s a significant task to review even the portfolio of components that come with WebLogic, let alone WebLogic compatible software from Oracle.

Performance Tuning

With considerations like migration and such a range of technologies to use, how can you be sure you’re getting the best performance out of your infrastructure? Consider the scenario – you have a suite of applications, migrated from OC4J which used to use AQ for messaging but now bridge endpoints with Oracle SAF. Are the defaults for the connection pools associated with your data sources optimal for persistent messaging?

It’s very common for users who are not familiar with performance concepts to get completely lost when trying to tune every aspect of their application and server. Should you buy more hardware? Do you need to? Performance issues can get very expensive, whether in terms of buying additional hardware, man-hours to maintain responsiveness or just in terms of your reputation to customers so it should never be an afterthought.

C2B2 offers Glassfish support by Steve Millidge

Oracle have just announced that commercial support for GlassFish 4 will not be available from Oracle. In light of this announcement I thought I would put together some thoughts about how I see this development.
I think the key word in this announcement is "commercial", nowhere does Oracle announce the "death of GlassFish" in contrary Oracle reaffirm;

GlassFish Server Open Source Edition continues to be the strategic foundation for Java EE reference implementation going forward. And for developers, updates will be delivered as needed to continue to deliver a great developer experience for GlassFish Server Open Source Edition so GlassFish is not about to go away soon. In a similar fashion RedHat do not provide commercial support for WildFly and only provide commercial support for JBoss EAP. Admittedly JBoss EAP and WildFly are much closer together than GlassFish and WebLogic but WildFly and JBoss EAP are absolutely NOT the same thing.
The key going forward to the viability of GlassFish as a production platform is how the GlassFish community develops;

  • How often does the community release binary builds?
  • How open is the community to bug fixes?
  • How much engineering resource does Oracle commit to GlassFish?

At this stage we just don't know the answers to these questions.

If the GlassFish open source project continues on it's current trajectory without a commercial support offering then I don't see much of a problem. Oracle just have to work harder to sell migration paths to WebLogic in the same way as RedHat have to sell migration paths from WildFly to JBoss EAP.

In the meantime  C2B2 continues to offer support for your operational JEE applications running on GlassFish and we will endeavour to work with the community to get any bugs fixed. The key difference is we can no longer back our Expert Support with a support contract from Oracle for patches and fixes for any release greater than 3.x. Read the complete article here.
