jXLS is Java component for exporting data to the Excel file format using XLS templates. It features simple property access notation, complex object graph export, flexible collection export, formula support, charts, macros, and many other Excel features in XLS templates, dynamic outlines, dynamic column hiding, dynamic cell style processing through custom CellProcessors, and JDBC ResultSet export.
The java.sql.ResultSet DOM Wrapper implements the Java DOM interface to represent a JDBC result-set. The resulting ResultSetDocument does not contain the actual result-set data and meta-data, but instead contains references to row and column indices. Because of this, it is very memory efficient, but it requires that the result-set be created with "scroll" capabilities. The wrapper is read-only, but since it implements the standard interfaces, it allows the use of transformers such as Xalan to perform XSLT transformation and XPath queries on the SQL result-set.
Javalogic is a library that leads to the creation of a visual implementation of application logic. This will allow the software developer to not worry about changing code against any rule modification. The software developer can delegate this to his customer, supplying him with a simple construction window.
javaSVNUpdater is a Java library that allows an application to update or patch itself automatically. The versioning information about the application needs to be stored in a subversion archive, and committing to the archive effects the distribution of new versions. It includes an updater wizard and an executor to spawn a separate process for proceeding with updates.
