codavaj is Javadoc in reverse: a seemingly useless reverse engineering tool to transform HTML Javadoc into Java source file skeletons (or a reflection API) like internal representation. You can: convert an entire local Javadoc tree into Java source code; download an entire remote Javadoc tree via HTTP(S); and derive a Reflection-like API based on information derived from a Javadoc tree. It is provided as a Java command line tool.
Jumpi is a simple, protocol agnostic, and extensible message passing communications API written in Java. The fully documented plug-in based reference implementation provides protocol adapters for MPI, TCP, UDP, JMS, Email, and HTTP for MIDP1.0 Midlets. The connectionless messaging paradigm can dramatically simplify client application code and is a complementary technology to JMS and RMI. Jumpi is compatible with Midp1.0, PersonalJava1.0, and J2SE.
protobuf-rpc-pro is a Java developer library that provides an RPC layer for Google's Protocol Buffer services. It builds upon Netty for low-level NIO. Features include bidirectional RPC calls from client to server and from server to client. The client and server are equal communicating peers. TCP connection re-use / keep-alive, SSL encryption support, RPC call cancellation, timeout and a pluggable logging facility logging RPC call data in Protocol Buffer format are included.
Webcockpit is a Web application generator for reporting and monitoring applications. It generates complete JSP-based Web applications which contain charts and tables whose contents are retrieved using database queries. The charts and tables can be configured to link to each other, enabling master detail-like drill-down. You can provide your own HTML or JSP template files which are mixed with the generated JSP to provide a final Web application.
