I need to convert XML data to Java objects. What would be best practice to convert this XML data to object?
Idea is to fetch data via a web service (it doesn't use WSDL, just HTTP GET queries, so I cannot use any framework) and answers are in XML. What would be best practice to handle this situation?

DOM Parser is the easiest java xml parser to learn. DOM parser loads the XML file into memory and we can traverse it node by node to parse the XML. DOM Parser is good for small files but when file size increases it performs slow and consumes more memory.
To unmarshal an xml string into a JAXB object, you will need to create an Unmarshaller from the JAXBContext, then call the unmarshal() method with a source/reader and the expected root object.
XML provides a universal syntax for Java semantics (behavior). Simply put, this means that a developer can create descriptions for different types of data to make the data behave in various ways with Java programming code, and can later repeatedly use and modify those descriptions.
JAXB is a standard API for doing this: http://java.sun.com/developer/technicalArticles/WebServices/jaxb/

Have a look at XStream. It might not be the quickest, but it is one of the most user friendly and straightforward converters in Java, especially if your model is not complex.
