Eclipse RCP: Tips 'n Trick

A MUST SEE Eclipse RCP demonstration .

The Eclipse Rich Client Platform provides a feature rich framework for the development of rich client applications. This talk presents tips and tricks for the development of such applications. Kai introduces some general development tricks that are helpful for all users of the Eclipse SDK, such as the usage of extension locations in combination with links, conditional breakpoints, and some logging tips.
It covers:
  • XML contributions vs. code

  • Package and Plug-in Structures

  • Deployment & Update

  • Issues when using 3rd Party Libraries

Serialize objects to XML and back again

XStream is a simple library to serialize objects to XML and back again.


  • Ease of use. A high level facade is supplied that simplifies common use cases.
  • No mappings required. Most objects can be serialized without need for specifying mappings.
  • Performance. Speed and low memory footprint are a crucial part of the design, making it suitable for large object graphs or systems with high message throughput.
  • Clean XML. No information is duplicated that can be obtained via reflection. This results in XML that is easier to read for humans and more compact than native Java serialization.
  • Requires no modifications to objects. Serializes internal fields, including private and final. Supports non-public and inner classes. Classes are not required to have default constructor.
  • Full object graph support. Duplicate references encountered in the object-model will be maintained. Supports circular references.
  • Integrates with other XML APIs. By implementing an interface, XStream can serialize directly to/from any tree structure (not just XML).
  • Customizable conversion strategies. Strategies can be registered allowing customization of how particular types are represented as XML.
  • Error messages. When an exception occurs due to malformed XML, detailed diagnostics are provided to help isolate and fix the problem.
  • Alternative output format. The modular design allows other output formats. XStream ships currently with JSON support and morphing
