How to use xstream fro xml serialization in eclipse

I am having some trouble figuring out how to download and use xstream in eclipse. When I download the binary distribution from the website, I get a zip file. Where should I extract it, and how do I use it?

Edit:

OK, I have added it to my build path, but now when I try to use XStream to serialize an ArrayList<Earmark> where Earmark is a class that I have defined, I get the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: org/xmlpull/v1/XmlPullParserException
at com.thoughtworks.xstream.XStream.<init>(XStream.java:334)
at examples.TestEarmarkExtractor.SerializeEarmarks(TestEarmarkExtractor.java:19)
at examples.TestEarmarkExtractor.main(TestEarmarkExtractor.java:48)
Caused by: java.lang.ClassNotFoundException: org.xmlpull.v1.XmlPullParserException
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
... 3 more

Update: The error is occurring before I try the serialization. It occurs on the line

XStream xs = new XStream();

I had added the two libraries: dom4j-2.0.0-ALPHA-2.jar and xstream-1.4.7.jar and the same issue were displayed. After adding the kxml2-min-2.3.0.jar the issue is not happening.

You can add this library:

    <dependency>
        <groupId>xmlpull</groupId>
        <artifactId>xmlpull</artifactId>
        <version>1.1.3.1</version>
    </dependency>

Got this exception, then I download kxml2-min-2.3.0.jar and add it as a library and now it works (using xstream 1.4.4.jar)

  1. Extract the zip file to a directory (e.g. C:\Program Files\XStream)
  2. In eclipse, right-click on your project and select Build Path > Configure Build Path...
  3. Select Libraries tab
  4. Select Add External Jars..
  5. Navigate to the lib folder of your XStream download and select the jar(s) to be added
  6. Select Open
  7. Select OK

And here's the Two Minute Tutorial on how to use XStream.

You need to unzip the .zip file to get at the .jar file, which you put on your classpath for your project in eclipse (Google if you don't know how to add third party library .jars to your project classpath in Eclipse).

Once it is added to your project's classpath, you use the classes contained within it as you would any other classes, and the documentation on the XStream website tells you how to use them.

Good choice by the way, XStream is great!
