Life is beautiful with XMLBeans and XStream

Posted on by

XML creation, parsing and processing with Java has gotten so much easier with tools like XMLBeans, XStream and many other such tools. I personally love XMLBeans and XStream and I try to use them for all of my XML processing needs. While they both consume XML, they solve different problems. XMLBeans allows you to process XML by binding it to Java types using XML schema that has been compiled to generate Java types that represent schema types. XStream on the other hand allows you to serialize objects to XML and back again using special reflective secret sauce.

I’ve been using these tools for many years now and so you tend to forget just how useful and powerful they are and how productive they make you. Case in point – A friend of mine came to me for help. He was building an application that would allow him to resale items from Amazon on his site and he wanted to use the Amazon eCommerce Web Services to search for products programmatically and update a local database that housed his content. Having played with Amazon E-Commerce Service (ECS) before, I offered to write up a simple application that would make the Web Services call, process the results and present them back to you.

Amazon’s ECS is an API that allows you to access Amazon data and functionality through a Web site or Web-enabled application. ECS follows the standard Web services model: users of the service request data through XML over HTTP (REST) or SOAP and data is returned by the service as an XML-formatted stream of text. In addition to the WSDL, ECS also provides XML schemas for validating the XML output of REST requests. So I decide to use XMLBeans to create my type system using the XML Schema provided by Amazon. XMLBeans provides you with a utility (scomp) to compile your schema into Java XMLBeans classes and metadata. To generate the Java code, use the following command:

scomp –jar amznws.jar AWSECommerceService.xsd

This generates a jar file named amznws.jar, which will contain all of the code needed to bind an XML instance to the Java types representing your schema. In my application, I use HttpClient to make my REST request and then use the XMLBeans generated jar file to process the result. Here’s a snippet of code from my sample class:

https://gist.github.com/311527.js

As you can tell, HttpClient makes the REST call a snap and XMLBeans makes processing the results easy as well. In total, I spent 3-4 hours getting the application working and a lot of the time was spent figuring out the data set returned from Amazon and trying to come up with a meaningful example. Here is a zip file with the IDEA project that has all the stuff needed to make this work including a simple JSP and a JUnit test class.

Get an in-depth look at the features and functionality of XMLBeans. This article introduces the technology with a simple example, takes you through the step-by-step process of compilation and binding, and discusses advanced features like XML cursors, tokens, and XQuery expressions. It also discusses how XMLBeans is more powerful than other XML-Java technology data binding techniques.

BEA looks to open-source part of WebLogic Workshop

Posted on by

Just saw this article on eWeek. The article states that BEA is slated to announce plans to open-source portions of its WebLogic Workshop tool at the upcoming eWorld conference. BEA has a pretty good record of supporting open-source software and the XMLBeans project is a good example of that. I think the support of AspectWerkz is another example.

If BEA does open-source some of the features of Workshop, this could really help the Eclipse Webtools platform project. I am not a Workshop power user by any stretch of the imagination, but it still does have some pretty cool features. It would be nice to incorporate things like page flow and some of the other cool features into the Eclipse webtools product – Give IntelliJ’s Fabrique a run for the money.

XMLBeans arrive @ Apache

Just caught this email in my mailbox and I’m really excited to see this development. I was blogging about this topic earlier and I am really glad to see this happen.

Kudos to BEA for donating XMLBeans to the Apache Group and kudos to Apache for accepting it. I am really excited about participating in this project and I’m downloading the source as we speak.

XML Beans: The Best of Both Worlds

Posted on by

BEA’s dev2dev site has an article titled XML Beans: The Best of Both Worlds on their cover page. XMLBeans is a pretty interesting technology from BEA that provides easy navigation of XML data using cursors or XQuery statements. In addition, Java classes representing the XML document is automatically generated based on the XML Schema provided. These generated Java classes enable easy read/write access to XML information and enforce XML Schema constraints. Pretty neat idea and it’s fast. And the support for XML Schema is pretty nice.

This brings up an issue as Sun has been pushing JAXB as the standard API/tool that automates the mapping between XML documents and Java objects. Will these 2 products directly compete or will BEA support JAXB completely in their product line? BEA has typically had a really good record of supporting and leading the charge on creation of new standards via. the JCP. Hitesh Seth, the author talks about it in his article and I second his hope that these initiatives converge at some point. ok.. Now back to Hibernate 🙂
