I have been tying to build a simple app (using VB.net) which lets a user index (in a similar manner to web logs) files which they have on their system. One problem I had was how to access the properties which are associated with an MS Office document (i.e. Title, Author etc.). This article provided the answer. You have to first download a DLL,
dsofile.dll, from MS: Thursday, February 12, 2004
Unit Testing and Mock Objects
One of the problems in writing unit tests is that often subsystems/objects need to be simulated in order to run the test. The current answer for the test infected is to use mock objects. This article in ONJava.com gives a review of what is currently happening in this area. It is interesting to see that the unit testing community is (slowly) moving towards a concept that has always been used in the chip industry, namely "Design for Test". The article ends with the hope that Aspect Orientated Programming (AOP) can make this all easier.

Extracting HTML Links
Could use httpunit
To fetch all links of a given URL use the following (from the cookbook):
WebConversation wc = new WebConversation();
WebResponse resp = wc.getResponse( "http://www.httpunit.org/doc/cookbook.html" ); // read this page
WebLink[] links = resp.getLinks(); // find the links
links[0].click(); // follow first
The class WebLink has methods such as " asText(), getURLString(), ..."
httpunit is able to cope with javascript within the pages.
Instead could use the HTMLEditorKit from Swing. See

More RSS
The goal of the Informa Project is to provide a RSS (Rich Site Summary) library based on the Java Platform
This article shows how to to use RSS with JSPs. Possibly transportable to Java.
RSS4j is a toolkit designed to generate and parse standards-conformant RSS

Topic Maps
Nexist is being developed based on a few hypotheses regarding Topic Maps (XTM) as an interface to a collaborative knowledge repository system. Nexist is a reference implementation for further collaborative development.
The goal of the TM4J Project is to develop robust, open-source tools for creating, manipulating and publishing topic maps
SemanText is a prototype application developed (in Phyton) to demonstrate how the topic map standard (ISO/IEC 13250:2000) can be used to represent semantic networks. Semantic networks are a building block for artificial intelligence applications such as inference engines and expert systems.

Web Service Management
This tool has an interesting non-evasive approach to WSM and is a technique which could be used in any integration architecture (WS or not)
