Polyglot Programming on the Web | Groovy Zone
Whether you like it or not, the web platform has become the dominant client-side technology. This fact is so obvious that even Microsoft and Adobe have abandoned their solutions in favour of the web. And as we’re going to build larger and larger applications in the browser, we need to find ways of doing it in a more productive fashion. I believe languages are a big part of it. And that’s where the Javascript community can learn a little bit from Java.

Transforming XML Data with XSLT | oracle.com

Transforming XML Data with XSLT

The Extensible Stylesheet Language Transformations (XSLT) APIs can be used for many purposes. For example, with a sufficiently intelligent stylesheet, you could generate PDF or PostScript output from the XML data. But generally, XSLT is used to generate formatted HTML output, or to create an alternative XML representation of the data.

In this section, you'll use an XSLT transform to translate XML input data to HTML output.

Java and XSLT: Chapter 5: XSLT Processing with Java

Since many of the XSLT processors are written in Java, they can be directly invoked from a Java application or servlet. Embedding the processor into a Java application is generally a matter of including one or two JAR files on the CLASSPATH and then invoking the appropriate methods. This chapter shows how to do this, along with a whole host of other programming techniques.

How to deal with "java.lang.OutOfMemoryError: PermGen space" error - Stack Overflow

Recently I ran into this error in my web application:

java.lang.OutOfMemoryError: PermGen space

It's a typical Hibernate/JPA + IceFaces/JSF application running on Tomcat 6 and JDK 1.6.
Apparently this can occur after redeploying an application a few times.

From Windows to Android with Glassboard | Nick Bradbury

Nick Bradbury: From Windows to Android with Glassboard

I can tell you that switching to Android wasn't easy after almost two decades of Windows development. I had to learn a new language (Java), a new IDE (Eclipse), a new platform (Android) and a new programming mindset (mobile) in a very short time. Oh, and just to make it harder, I decided to do it all on a Mac. I guess you could say I was looking for a challenge :)
And a challenge it definitely was.

Java 7: What's In It For Developers - Slashdot

GMGruman writes "After five years of a torturous political process and now under the new ownership of Oracle, Java SE 7 is finally out (and its initial bugs patched in the Update 1 release). So what does it actually offer? Paul Krill surveys the new capabilities that matter most for Java developers, from dynamic language support to an improved file system."

Rapid Cloud Development with Spring Roo – Part 2: VMware Cloud Foundry | Javalobby

Spring Roo is a tool to offer rapid application development on the Java platform. I already explained when to use it: http://www.kai-waehner.de/blog/2011/04/05/when-to-use-spring-roo. Spring Roo supports two solutions for Cloud Computing at the moment: Google App Engine (GAE) and VMware Cloud Foundry. Both provide the Platform as a Service (PaaS) concept. This article will discuss the Cloud Foundry support of Spring Roo. GAE was discussed in part 1 of this article series (http://www.kai-waehner.de/blog/2011/07/18/rapid-cloud-development-with-spring-roo-%E2%80%93-part-1-google-app-engine-gae).

Lisandro writes "Lucid Imagination just posted an announcement about a severe bug in the recently released Java 7. Apparently some loops are mis-compiled due to errors in the HotSpot compiler optimizations, which causes programs to fail. This bug affects several Apache projects directly — Apache Lucene Core and Apache Solr have already raised an warning, noting that the bug might be present in Java 6 as well."

GWT 2 Spring 3 JPA 2 Hibernate 3.5 Tutorial - Java Code Geeks

GWT 2 Spring 3 JPA 2 Hibernate 3.5 Tutorial - Java Code Geeks

This step by step guide will present how to develop a simple web application using Google's Web Toolkit (GWT) for the rich client and Spring as the back – end, server side framework. The sample web application will provide functionality to make CRUD (Create Retrieve Update Delete) operations to a database. For the data access layer we will use JPA over Hibernate and for a database we will use Hypersonic. Of course you can change the configuration and use whatever you like. We will deploy the web application to an Apache – Tomcat instance.

Inspired by Actual Events: Book Review: Java: The Good Parts

I recently had the misfortune of waiting at the airport for roughly six hours as my flight was repeatedly delayed 30 minutes at a time until it was ultimately canceled. The one silver lining in this cloud was that I was able to read almost all of Jim Waldo's Java: The Good Parts while I waited (the book comes in at under 200 pages). In this post, I talk about what I like best about this book and who I believe its best audience is.

Inspired by Actual Events: O'Reilly's OSCON Chairman: "Java deserves another look"

I frequently wholeheartedly agree with opinions expressed by Java.net editor Kevin Farnham in his Editor's Blog. Nevertheless, I was still surprised to discover that his most recent post (Is Java Becoming an 'Emerging Technology'? Ask O'Reilly) seemed to capture and even better articulate my own recent thoughts after reading the same three O'Reilly posts (all by Edd Dumbill) he references: Seven reasons you should use Java again, Seven Java projects that changed the world, and A rough guide to JVM languages. Each of the three Dumbill/O'Reilly posts is well worth reading on its own merits, but what really struck me is the overall observation I made as I read these posts: this might be O'Reilly's way of saying "Java is back!"

Model Two Zero: Running Cloud Foundry on Amazon EC2 (or any Ubuntu server!) and Deploying Using STS

Model Two Zero: Running Cloud Foundry on Amazon EC2 (or any Ubuntu server!) and Deploying Using STS

The idea with Cloud Foundry is that you can run it on any cloud infrastructure - hence the separation of cloudfoundry.org and cloudfoundry.com. The former is the open-source project that is building the infrastructure software, the latter is a commercial offering by VMWare.

So here's what this is about:

• Running Cloud Foundry on EC2 instead of the out-of-the-box cloud VMWare provide
• Connecting Spring STS to it
• Getting a grails app deployed
