UltraESB is the first [and still the only] Open Source Enterprise Service Bus (ESB) to utilize Zero-copy proxying with Memory Mapped files and Java Non-Blocking IO for extreme performance!
Scannotation is a Java library that creates an annotation database from a set of .class files. This database is really just a set of maps that index what annotations are used and what classes are using them. Why do you need this? What if you are an annotation framework like an EJB 3.0 container and you want to automatically scan your classpath for EJB annotations so that you know what to deploy? Scannotation gives you apis that allow you to find archives in your classpath or WAR (web application) that you want to scan, then automatically scans them without loading each and every class within those archives
There are really 3 main classes to Scannotation: ClasspathUrlFinder, WarUrlFinder, and AnnotationDB. The first step in scanning for annotations is declaring what archives or what parts of your classpath you want to scan in. ClasspathUrlFinder has various ways to automatically find the URLs that make up your classpath. WarUrlFinder is similar but provides ways to get things from your WAR lib directory.
Once you find the URLs that make up your classpath, you feed them to AnnotationDB to scan and index. Its best to read the javadocs
nexusBPM is an open-source enhancement of JBoss's jBPM product suite. We have added many features to both the editor and the engine.
nexusBPM provides en enhanced editor experience with a variety of preconfigured nodes such as FTP, SQL, Excel and others. All nexusBPM nodes can participate in dataflow which is very easy to use. Using dataflow means that information created by one node can be used by another for processing, formatting, output or decision making. The nexusBPM editor can even communicate with the nexusBPM server andsupports drag and drop upload and download capabilities as well as remote run commands.
nexusBPM provides an enhanced engine with support for scheduling flows using quartz, executing nexusBPM nodes using message driven beans and custom commands.
Elastica is a highly efficient and extensible, rules-based load-balancer for JBoss that adds dynamic behavior to EJB load balancing. Rules can be defined to redirect EJB requests according to request data, server performance data, or even the time of day
This is an early implementation of JSR 303 (Bean Validation), a specification of the Java API for JavaBean validation in Java EE and Java SE.
The technical objective is to provide a class level constraint declaration and validation facility for the Java application developer, as well as a constraint metadata repository and query API.
This implementation is based on the validation framework of agimatec GmbH, that is in production for more than a year and offers additional features, like XML-based extensible metadata, code generation (JSON for AJAX applications), JSR303 annotation support.
