To expand on the "use JAXB" comments above, 

In Windows
 <code>"%java_home%\bin\xjc" -p [your namespace] [xsd_file].xsd</code>

e.g., 
 <code>"%java_home%\bin\xjc" -p com.mycompany.quickbooks.obj quickbooks.xsd</code>

Wait a bit, and if you had a well-formed XSD file, you will get some well-formed Java classes

blocks|key|1381618|text|最简单的方法是使用命令行。只需键入您的.xsd文件的目录：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1381619|xjc+myFile.xsd.|code-block|syntax|javascript|1381620|所以，java将生成所有的Pojos。|1381621|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

the easiest way is using command line. Just type in directory of your .xsd file: 

<pre><code>xjc myFile.xsd.
</code></pre>

So, the java will generate all Pojos.

Maven can be used for the purpose, you need to add some dependencies and just clean your application. You will get all classes created automatically in your target folder.
Just copy them from target to desired place, here is <code>pom.xml</code> that I have used to create classed from <code>xsd</code> files:
<pre class="lang-xml prettyprint-override"><code>&lt;plugin&gt;
 &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt;
 &lt;artifactId&gt;jaxb2-maven-plugin&lt;/artifactId&gt;

 &lt;executions&gt;
 &lt;execution&gt;
 &lt;goals&gt;
 &lt;goal&gt;xjc&lt;/goal&gt;
 &lt;/goals&gt;
 &lt;/execution&gt;
 &lt;/executions&gt;
 &lt;configuration&gt;
 &lt;schemaDirectory&gt;src/main/webapp/schemas/&lt;/schemaDirectory&gt;
 &lt;/configuration&gt;
&lt;/plugin&gt;
</code></pre>
Just place your xsd files under <code>src/main/webapp/schemas/</code> and maven will find them at compile time.

JAXB Limitation.

I worked on JAXB, as per my opinion its a nice way of dealing with data between XML and Java objects. The Positive sides are its proven and better in performance and control over the data during runtime. With a good usage of built tools or scripts it will takes away lot of coding efforts.

I found the configuration part is not a straight away task, and spent hours in getting the development environment setup.

However I dropped this solution due to a silly limitation I faced. My XML Schema Definition ( XSD ) has a attribute/element with name "value" and that I have to use XSD as it is. This very little constraint forced the my binding step XJC failed with a Error "Property 'Value' already used."

This is due to the JAXB implementation, the binding process tries to create Java objects out of XSD by adding few attributes to each class and one of them being a value attribute. When it processed my XSD it complained that there is already a property with that name.

blocks|key|1381306|text|JAXB的XJC难道不是一个可能的解决方案吗？我也在努力实现同样的目标。不过，它仍处于“尝试”阶段。偶然发现了XJC，所以想到了分享。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1381307|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Isn't JAXB's XJC is a possible answer to this? I'm trying to achieve the same thing. Still in the "trying" phase though. Came across XJC, so thought of sharing.

Talking about JAXB limitation, a solution when having the same name for different attributes is adding inline jaxb customizations to the xsd:

 binding declarations

or external customizations...

I have a gigantic QuickBooks SDK .XSD schema file which defines XML requests/responses that I can send/receive from QuickBooks.

I'd like to be able to easily generate Java classes from these .XSD files, which I could then use to marshal XML to Java objects, and Java objects to XML. 

Is there an easy way to do this...? 

Ideally, it would not require any libraries external to the basic Java distro at run-time. But I'm flexible...

Generate Java classes from .XSD files...?

Windows

Java

我有一个巨大的XML模式文件，它定义了我可以从QuickBooks发送/接收的QuickBooks请求/响应。我希望能够轻松地从这些.XSD文件生成Java类，然后使用这些文件将XML编组为Java对象，并将Java对象编组为可扩展标记语言。有没有简单的方法可以做到这一点……？理想情况下，它在运行时不需要基本Java发行版之外的任何库。但我很灵活..。
