This article shows how to use them to understand a UI's structure, test how it functions, and troubleshoot issues. http://www.java-channel.org/display.jsp?id=c_21832 Walk through the steps of incorporating OpenID into a sample Java application. Rather than implement the OpenID Authentication specification by hand, author J. Steven Perry uses the openid4java library and a popular OpenID provider, myOpenID, to create a safe and reliable registration process for a Java application written in Wicket. http://www.java-channel.org/display.jsp?id=c_21806 The TDA Thread Dump Analyzer for Java is a small Swing GUI for analyzing Thread Dumps and Heap Information generated by the Sun Java VM (currently tested with 1.4.x, 1.5.0_x and 1.6.0_x releases). It parses the thread dumps and class histograms from a provided log file. TDA needs at least Java 1.4.2_x to run. It provides statistic informations about the found thread dumps, gives information about locked monitors and waiting threads. It can diff between threads to look for similarities and has a "long-running-thread" detection. It also provides overview of heap objects at a thread dump, if class histogram was logged. http://www.java-channel.org/display.jsp?id=c_21793 Recently, the popular open source search library, Apache Lucene, and the powerful Lucene-powered search server, Apache Solr, have added spatial capabilities. Lucene and Solr committer Grant Ingersoll walks you through the basics of spatial search and shows you how to leverage its capabilities to power your next location-aware application. http://www.java-channel.org/display.jsp?id=c_21779 OAuth is an open protocol that enables users to share their protected resources among different Web sites, without risking exposure.
