NetOculus is a network monitoring system that provides all the functions of the well-known monitoring system MRTG. It also has a number of its own benefits. It can automatically monitor any kind of detectable alteration in a computer network (and in relatively separated network areas). It can efficiently notify staff about hardware state changes. Analytical information is aggregated. Specific pieces of hardware are associated with the staff members who responsible for them. The solutions for solved problems are reported to the staff for further use.
OpenXava is a framework to develop AJAX JavaEE/J2EE applications rapidly and easily. It allows you to define applications only with POJOs, JPA, and Java 5 annotations. It is feature rich and flexible. It generates JSR-168 portlet applications (Liferay, WebSphere Portal, Jetspeed, etc.).
Java Inherited Annotations is a library of inherited annotations for developers solving the annotation inheritance task. The annotations being inherited are of classes, interfaces, or their methods. It uses the consistent inheritance model: inheritance proceeds only if the same annotation is not present on the same element (class, interface, or method) within superclasses or superinterfaces. Annotations can be overridden within descendants.
