JAXB with Maven

Finally Sun has Maven repositories for getting Sun jars and also they have a nice plugin for generating JAXB 2 classes with Maven using the maven-jaxb2 plugin. It defaults to generating schemas located in src/main/resources and the generated output goes to target/generated-sources/xjc. The generated output will automatically be included in your final jar.

Spring by Example Site is Open!

The Spring by Example site is finally open! I've been working this for a couple of months, but wanted it to be fairly nice when it went live. It has a few good examples and I have more to post. A few people I know have said they will contribute examples as they have time also. These are some of my favorite examples posted so far.

• Custom Thread Scope
• Spring custom scope implementation for thread scoped beans.
  
• Dynamic Tiles Spring MVC Module
• Have a default Tiles definition that takes the url of an incoming request and assumes it should be the request body and dynamically inserts the url into the default definition.
  
• Spring by Example JDBC
• Some nice utitlies for helping initialize scripts and to make it easier using HSQL DB. They are especially useful for unit tests.
  
• Spring by Example JCR Module
• Utilities for helping to recurse through JCR Nodes.
  
• Spring by Example Util's HttpClientTemplate
• Callback template around Commons HttpClient.
  
• Spring by Example Util's HttpClientOxmTemplate
• Callback template around Commons HttpClient that uses Spring OXM to marshall and unmarshall XML for HTTP requests.

Tim Voet also posted an example using a BeanPostProcessor to dynamically insert a logger based on the bean's class if it has a setLogger method. This is a nice way to avoid typos when creating loggers.
