jniThreadCPUUsage is a Java library to get the amount of user and system CPU time used per thread. This is done via JNI, which calls getrusage() on the system. getrusage() is only available on Linux 2.6.26 or later and Solaris. One useful application of this is measuring the amount of CPU time used for a servlet request. getrusage() CPU time reporting is better than using the real time clock because it measures actual CPU time used and disregards times when the thread is idle or waiting (such as when it is waiting for network I/O).
The OGSA-DAI Trigger component provides a mechanism to notify an OGSA-DAI server when a table in an SQL database has had its rows modified. It then executes a stored OGSA-DAI workflow to perform an action based on the notification. The trigger also provides the old and new values for the modified row which allows specific actions to be taken based on the exact database changes. These actions can use the full range of access, transformation, and delivery functionality available in OGSA-DAI.
The Maven License Verifier Plugin is a Maven plugin that is intended to check the licenses of artifacts managed by Maven. This can be done during the build process, you can choose to let the build fail if an artifact with a wrong license is used. The licenses are categorized by a definition file that lists them with their different URLs and names. This can be different from project to project.
