MetaClass supports runtime access to metadata associated with Java program elements or artefacts. The program elements include packages, classes, methods, and fields and each metadata element is referred to as an attribute. The attributes are usually specified in the Java source files as JavaDoc markup. The source file is then processed and the metadata is compiled into descriptors that MetaClass is capable of reading. These descriptors are then loaded at runtime to provide metadata about the program elements.
MicroNova YUZU is an EL-based JSP tag library designed to augment JSTL and transform JSP into a powerful XML-style "scripting language" (compatible with both JSP 1.2 and 2.0). Features include: stackable (nestable beyond tagfile boundaries) tags, nestable/encodable map with XML/JSON support, "codec" functions, structured param with file upload/select/radio support, "subroutine" call returning non-string Object, dynamic embedded EL pattern evaluation for regular text and SQL queries, HTTP client and response control, an HTML-to-DOM parser, multipart email and mailbox, dynamic method invocation/iterator/map/resource message map, and more. All YUZU tags follow a single behavioral pattern (prepare, import, default, process, assign, export) for ease of learning and extension.
