XStream provides a TraxSource (extends SAXSource) that can be used as an input to XSLT transformation. The TraxSource uses a java Object and the corresponding XStream Object. The java object can then be directly converted to XSLT target without actually converting to XML. Lets look at an example package com.studytrails.xml.xstream; import java.util.ArrayList; import javax.xml.transform.Transformer; import … Read more

XStream can also be used with JSON. XStream provides two drivers : a JsonHierarchicalStreamDriver and a JettisonMappedXmlDriver. The JsonHierarchicalStreamDriver can be used to write a JSON string but cannot deserialize a JSON. JettisonMappedXmlDriver can be used to deserialize a JSON but it introduces an additional dependency. In this example we deserialize a json string into … Read more

In the earlier tutorials we saw how to convert a Java object to XML and back, custom converter and basic converters.

In the previous tutorials we saw an example of how to convert java object to XML and back. That tutorial also explained the concept of aliases and implicit collection.In the last tutorial we show how to write a custom converter. In this tutorial, lets see some of the basic built in converters of XStream and … Read more

In the previous tutorials we saw an example of how to convert a java object to XML and back. That tutorial also explained the concept of aliases and implicit collection. While serializing a Java object to XML XStream uses custom converters. These converters specify how to create XML from a Java Object or how to … Read more
