Grails is focused on developer productivity more than raw speed, but that doesn't mean it's a slouch. When you do need better response times, there are plenty of options available - as this video talk will demonstrate. Find out both how to isolate ... [More] performance issues and what you can do to fix them. This is a large and complex area, so the focus will be on Grails-specific solutions.

Welcome back to another installment of "This Week in Spring." Today saw a new sunrise, and - more importantly - the release of vSphere 5, the next step in cloud infrastructure! My head's still buzzing after the excitement that accompanied ... [More] this morning's launch. This - and the recent release of vFabric 5 - represent the next stage in cloud innovation, and a huge part of taking your applications to production, and to the cloud, with Spring. O'Reilly has published a fantastic roundup on the seven Java projects that changed the world! The list includes JUnit, Eclipse, Solr, Hudson and Jenkins, Hadoop, Android, and your favorite enterprise Java framework and mine, the Spring Framework. Martin Lippert has announced a new release of SpringSource Tool Suite, version 2.7.1, hot on the heels of the recent 2.7 release. The update provides: support for Spring Roo 1.1.5, ships with Spring Roo 1.1.5, and customizable Roo Shell colors. More details on new features and bug fixes can be found in the New and Noteworthy document. Detailed installation instructions are also available. As always downloads are available from the STS download page. Gordon Dickens has a great look at some of the cool places to start poking around in SpringSource Tool Suite 2.7.x on your first flight. Gordon, as you know if you read last week's column, is the author of the DZone RefCard for SpringSource Tool Suite. The Spring Roo team has announced Spring Roo 1.1.5. The new release features over 95 improvements and bug fixes since the 1.1.4 release. The next release of Roo will be 1.2.0.RC1 where new features such as application layering support and a new JSF UI option will be introduced. Martin Lippert announced that the latest version of the SpringSource Tool Suite and CloudFoundry Integration, version 2.7.0.M3, has been released. This is the latest release of the integration initially announced and explained on this blog. If you were unable to attend the recent S2G Forums in London and Amsterdam, you can catch up on some of the session content because the presentations have now been posted on line. In particular, you can review the slides presented in Rod Johnson's keynote: What can the cloud do for me? Of course there will be more fantastic content at SpringOne 2GX 2011, October 25-28th in Chicago. Be sure to register early. This blog post does a great job illustrating how to embed Apache Tomcat 7. Cool stuff! VMware's knowledge base has so much knowledge, so much wisdom, that scarcely the largest, and most scalable Not-Only-SQL solution can contain it. One of the many gems contained in this knowledge base? A recently added post on converting EJB applications to Spring, which references the very successful Hyperic case-study. Check it out if you're looking for insight from the professionals on how to forge from the bloated, boilerplate ridden code of a typical EJB application a clean, scalable Spring solution grounded in best practices.

Welcome back to another installment of "This Week in Spring." If you're in the US, then you've just returned from a long weekend and are no doubt ready for some great content to read and reinvigorate your creativity. If you're not in the US ... [More] , then you're probably already deep into a week of coding and keen on something to inspire you. Well, look no further, in any event. You've come to the right place. SpringSource Tool Suite, version 2.7.0, has just been released! This release includes a lot of new functionality as well as enhancements. STS is the premiere environment for enterprise Java developers, and freely available. This release is the first to ship on top of the newly released Eclipse Indigo (3.7), it includes Mylyn 3.6 and EGit 1.0, updated template projects, support for Grails 1.4.M1, Grails-aware rename type refactoring, Groovy-Eclipse 2.5.1 (which includes support for Groovy 1.8 and DSL IDE support (DSLDs)), and support for Gradle. DZone has just published a reference card ("refcard") on the SpringSource Tool Suite (STS). Charles Lee blogs about the new Cloud Foundry plugin available for the Hyperic management and monitoring solution. Good stuff, check it out! Be sure to visit the CloudFoundry page to get started. The Spring Social Quick Start has been updated to reflect the latest and greatest standards, definitely a valuable resource to have! Spring Social is a framework designed to connect your applications to the various social networks, including Twitter, Facebook, and more. Dave Syer tweets about some of the very interesting new features in Spring 3.1 supporting refreshable Groovy beans. Good stuff! WaveMaker 6.3.2 GA was released recently. Beginning with this release all WaveMaker source code is licensed under the Apache license, version 2.0. This is the first GA release of WaveMaker since being acquired by VMware. Releasing WaveMaker as 100% open source demonstrates VMware's commitment to open source and to the WaveMaker user community. If you're looking for more information on WaveMaker, we would humbly recommend these screencasts. We've got a couple of good posts this week on setting up SSL in Tomcat. One of Tomcat's most powerful features is its strong community, serving both the novices and the grizzled taking the last steps in the march towards production. The first post is called Setting Up SSL on Tomcat in 5 Minutes. A second, more nuanced post, called SSL Your Tomcat 7, expands on the options available in configuring the keystore. Spring Security can also help your application play well with SSL. It can automatically handle requiring SSL on access to certain pages, redirecting to it on login, etc. Mark Thomas (on the ever-reliable TomcatExpert.com) has a great post on some of the great features in Tomcat 7 that are now available in Tomcat 6. Bozho has put together an interesting discussion of using Spring and PersistenceContextType.EXTENDED in JPA. Using the Play framework with Spring? The Play framework has a Spring module which makes accessing Spring beans very easy. However, some trickery - as this post explains - is required to access those javax.sql.DataSources to drive the model classes in the Play framework. Interesting post. Alex Soto has an interesting blog on a JdbcTemplate-style object that can be used to interface EJP (Easy Java Persistence). Mapping database records to Java objects can be painful, and it's good to see healthy, lightweight alternatives to support your Spring applications. Hiring Spring developers? Be sure to consult the Core Spring 3.0 Certification study guide to inform your interview questions and, if you have people you want to take the next step in their education, consider the Spring certification program. Of course, if you have serious development skills there are openings to join the SpringSource team at VMware. It's a great place to work. [Less]
