Welcome to another installment of This Week in Spring! It's been an exciting week for Spring at Pivotal, which you can hear more about at the re-scheduled Pivotal launch event on April 24th. In case you are reading too fast, Pivotal has ... [More] re-scheduled the launch event to April 24th. Register here! Arjen Poutsma has announced Spring Web Services 2.1.3.RELEASE. The new release mainly consists of bug fixes, for the full details check out the changelog. Don't miss the upcoming Webinar with Donald Miner and Mark Pollack discussing Pivotal HD and Spring Hadoop, a good introductory webinar for those that are Pivotal HD-curious. New SpringOne2GX replays now available in HD on YouTube: Cloud Foundry Architecture, Effective Design Patterns in NewSQL There was a great post on Reddit the other day that explains the difference between REST and SOAP in terms of Martin Lawrence. This has nothing to do with Spring, but was droll enough that it's worth sharing. Spring, of course, has an amazing REST stack and I highly encourage people to check out how to build consolidated, streamlined REST services with Spring! Moving on... :) James Rossiter has a good post on how to use a Spring InitBinder to Resolve Type Mismatch and bind Exceptions in POST from Spring MVC to Controller Actions. @olivergierke brings up a great point on Twitter: how much code does it take to add the JTA 1.2 JSR javax.transaction.Transactional annotation to Spring? Almost nothing! Most of the code here is just unit tests. Otherwise, this is just a dead simple mapping of the JTA annotation to Spring's already supported engine, which also currently supports the native Spring @Transactional and @javax.ejb.TransactionAttribute annotation. Are you looking into Gradle and want to get started with Spring, quickly? Giancarlo Frison has put together a nice post with a bootstrap Gradle build that can be used with Spring applications. Eugen Paraschiv has put together a nice post on how to use RestTemplate to do HTTP BASIC authentication. Spring has long supported a utility class, called the org.springframework.util.StopWatch, which can be used to measure the execution of method invocations. The Javarevisited blog has a nice post on how to use the StopWatch class. This post is fairly old, but I just stumbled upon it and thought it was a well thought out presentation introducing Aspect Oriented Programming (AOP) in Spring. [Less]

Cloud Foundry Architecture If you have deployed applications on Cloud Foundry, you know how easy it is to push an app, bind services to it, and scale it. There are more magical things behind the scenes. Did you know, for example, that ... [More] cloudfoundry.com is updated approximately twice a week? Each update included small changes such as a bug fix or a new feature, but often large changes such as updating the underlying operating system. Yet, we can do all this without any downtime for user apps. Come to this talk to understand what makes this possible. Even if you aren't going to ever implement a PaaS on your own (and why should you? we already give you a good one!), the architectural ideas apply to your distributed apps quite well.

Welcome to another installment of This Week in Spring! As usual, we've got a lot to cover, so let's get to it! SpringSource CTO Adrian Colyer outlines the direction and momentum of SpringSource and the Spring projects under the ... [More] Pivotal Initiative, a new company spun out of EMC comprised of - among other things - SpringSource, Cloud Foundry, and GreenPlum. This is definitely worth a read if you want to understand Spring's - ahem - Pivotal role in this new initiative! Spring Batch lead Michael Minella has announced that Spring Batch 2.2.0.RC1 is now available. The new release includes preliminary support for Spring Data, Java configuration support, non-identifying job parameters and numerous fixes and polishes. This release is amazing, and definitely worth a look. I, personally, love the Java configuration API that's been surfaced. You don't need to write another Spring Batch XML file if you don't want to! Spring Mobile lead Roy Clarkson has announced that Spring Mobile 1.1.0.M3 has been released featuring simpler configuration when using a custom domain strategy with SiteSwitcherHandlerInterceptor, support for Kindle Fire device detection (as tablet or mobile depending on which mode they are in), several resolved issues and compatibility with Spring Framework 3.2.2. New SpringOne2GX replays now available in HD on YouTube: Virtualizing and Tuning Large Scale Java Applications, From Spring and Java to Spring and Akka The HMK blog has a really nice post on how to use the Cujo.js's rest.js and Spring MVC. Very cool! The JavaRevisited blog has put together a post on calling stored procedures from Spring using the StoredProcedure template object. There are other ways to approach this same problem, including the SimpleJdbcCall object and simply using the update(String, Object ... params) method on JdbcTemplate. Check it out! The Spring Java Tutorial blog has a nice post on using stored procedures with Spring, and it also uses the same domain example - an EmployeeDAO. They aren't exacty the same - far from it - but it does seem like one heckuva coincadence! At any rate, more information's always good. Spring provides various lifecycle callback methods, which this JavaBeat blog looks at. The Binary Beans blog has a post that simply links to some interesting, introductory videos that we've published on the SpringSourceDev YouTube Channel. If you're a regular reader of this round up then you've seen these videos before. But, it's a good 3 hours of introductory content and worth a look if you want a good getting started experience. KH Yiu has put together a cool post introducing the concept of a factory pattern (which you're no doubt already familiar with!) in application code, built with Spring. This is not about how Spring uses the factory pattern, and was kind of an interesting approach. Nicely done! Daniel Wong put together a really cool blog illustrating how to tie together Spring MVC with OpenCMS! Definitely worth a look. The 11th Hour blog put together a nice post on how to use the Spring Expression Language with some examples. Wang Xiang's put together a blog.. more like a series of snippets.. demonstrating how to setup Jetty, a DataSource, and Spring together. The Java Code Geeks blog has an introductory post on using Spring MVC with JSR 303 bean validation. Check it out! Our pal Mark Serrano is back, this time with a review of Spring Security lead Rob Winch's book on Spring Security. Hippoom Zhou has put together a nice post introducing how to use mocks and stubs in Spring Integration tests. This is a very nice post, and definitely worth a look! The awesomely named Raging Goblin blog has a nice post on how to do role-based views using Spring Roo and Spring Security. Peter Chng describes a scheme that can be used to auto-register custom converters used for data type conversion in core Spring, Spring MVC, and Spring Integration, among other places. Pretty smart!

Virtualizing and Tuning Large Scale Java Applications This session shares many of the production proven methods of running Java on vSphere. Covering how to size JVMs, and VMs for large scale deployments. The session will have a special section ... [More] on GC tuning and show how a wide range of JVMs can be tuned using a GC recipe developed over the past 15 years of actual field experience in tuning JVMs. Three key trends and associated tuning techniques are discussed in this session. The key trends are: Consolidation, Elasticity and Flexibility, and Performance Consolidation Many of our customers find that their middleware deployments have proliferated and are becoming an administrative challenge associated with higher costs. We see a trend across customers who look to virtualization as a way of reducing the number of server instances. At the same time, customers are taking the consolidation opportunity to rationalize the number of middleware components needed to service a particular load. Middleware components most commonly run within a Java Virtual Machine (JVM) with an observed scale of 100 to 1000s of JVM instances and provide many opportunities for JVM instance consolidation. Hence, middleware virtualization provides an opportunity to consolidate twice – once to consolidate server instances, and, secondly, to consolidate JVM instances. This trend is far-reaching, because every IT shop on the planet is considering the cost savings of consolidation. One customer in the hospitality sector went through the process of consolidating their server footprint and at the same time consolidated many smaller JVMs that were less than 1GB heap. They consolidated many of these smaller 1GB JVMs into 2 categories, those that were 4GB, and others that were 6GB. They performed the consolidation in such manner that the net total amount of RAM available to the application was equal to the original amount of RAM, but with fewer JVM instances. They did all of this while improving performance and maintaining good SLAs. They also reduced the cost of administration considerably due to the reduced number of JVM instances they had to manage, and refined environment that helped easily achieve SLA. Another customer, in the insurance industry, was able to achieve the same as the above customer, but additionally was able to over-commit CPU in development and QA environments in order to save on third party software license costs. On the other hand, sometimes we come across customers that have a legitimate business requirement to maintain one JVM for an application, and/or one JVM per a line of business. In these cases, you cannot really consolidate the JVM instances, as that would cause intermixing of the lifecycle of one application from one line of business with another. However, while such customers don’t benefit from eliminating additional JVM instances through JVM consolidation, they do benefit from more fully utilizing the available compute resource on the server hardware, that otherwise would have been underutilized in a non virtualized environment Elasticity and Flexibility It is increasingly common to find applications with seasonal demands. For example, many of our customers run various marketing campaigns that drive seasonal traffic towards their application. With VMware, you can handle this kind of traffic burst, by automatically provisioning new virtual machines and middleware components when needed, and then automatically tear down these VMs when the load subsides. In addition, the ability to change updating/patching hardware without causing outage is paramount for middleware that supports the cloud era scale and uptime. VMware VMotion gives you the ability to move VMs around without needing to stop applicators and or the VM. This flexibility alone makes virtualization of middleware worthwhile when managing large-scale middleware deployments. One customer in the financial space, handling millions of transactions per day, used VMotion quite often to schedule their hardware upgrades without any time downtime. What otherwise would be a costly scheduled downtime to their business. Performance Customers often report improved middleware platform performance when virtualizing. Performance improvements are partly due to the updated hardware that customers will typically refresh during a virtualization project. There is also some performance improvement due to the robust VMware hypervisor. A recent customer that reported a great level of performance provided the following testimony “With our OrderExpress project we upgraded our Middleware Services, Commerce, Portal, WCM, Service Layer, DB2 Database; migrated from AIX to Linux; virtualized on VMware; moved the application into a three-tier DMZ; increased our transactions by over 150 percent; and added significant new capabilities that greatly improved the customer experience. Changing such a wide range of technology components at once was a huge challenge. However using VMware vSphere and additional architectural changes we were successful in improving performance by over 300 percent; lowered costs in the millions; improved security, availability, and scalability; and how we plan to continue evolving this application to maintain greater than 30 percent yearly growth.” – Jeff Battisti, Senior Enterprise Architect at Cardinal Health In this session, I will show some actual JVM and VM sizes for middleware components both small and large JVMs. Will also detail out GC tuning recipe that I have developed over the years,that has been shown to handle JVM heap sizes form 4GB to 88GB+, and higher. Of course the introduction of in-memory databases has driven the trend to have these larger JVMs and hence why we will discuss what is the best way to tune the JVM, VM, and the hardware platform they are deployed on. I see the sizing question as the most commonly asked question with our customer base,and as a result I plan to focus on it during the session.

Emad has previously presented at VMworld, SpringOne, and Open World on the subject of Java virtualization. More About Emad »   From Spring + Java to Spring + Akka - A Journey of Discovery Actor based concurrency model is a paradigm shift. What is paradigm shift? A change in the basic assumptions, or paradigms, within the ruling theory of science. A paradigm shift makes simple ideas hard to grok. Even though Actor model is a simple and revolutionary idea it becomes hard for programmers to see practical benefits and usage. Similarly, the Scala programming language brings a lot to the table in simplifying actor-based design, but comes with a new style of coding. One possible solution to this problem is to evaluate the new paradigm in terms of old paradigm. In this presentation we will take a working Spring based web application and gradually implement it using actors and Scala. We will be skeptical and suspicious of new ideas but at the same time we will be open minded. We will learn about actor based concurrency model using the knowledge of spring. At the same time, we'll learn best practices behind Actors, Scala and combining these with the Spring Framework.
