Java for C++ is a tool to generate C++-wrapper-classes for existing Java-classes. This tool reads a list of Java class names and creates source code for C++-classes to wrap them.
The implementation of the wrapper classes uses JNI (Java Native Interface) to call the "real" Java classes.
The C++-API to use these wrapper classes is very close to the API of the original Java classes. So developers of C++-software can use Java-classes as if they have been implemented in C++.
Enhancements:
- A problem where null values for method arguments, method return values, or field values caused some generated code to crash was fixed.
- Updating is strongly encouraged.

Database Independent Abstraction Layer for C (libdbi) implements a database-independent abstraction layer in C, similar to the DBI/DBD layer in Perl.
Writing one generic set of code, programmers can leverage the power of multiple databases and multiple simultaneous database connections by using this framework.
Main features:
Database-level abstraction:
Your programs dont need to deal with the arbitrary interfaces and oddities of each database library. libdbi handles all the details for you, you just tell it what you want the database to do.
Modularity:
Since database code written with libdbi is not tied to one specific database server, you can effortlessly switch databases or give your users the option to specify their own database settings.
Clean interface:
With ample documentation describing libdbi and its well thought out object-oriented design, programming with libdbi should be less painful than programming with native database libraries. And you only need to learn it once instead of learning each database librarys syntax.
Accommodates coder apathy:
libdbi is written to do The Right Thing(tm), not just some quick hack that does the job in a half-assed fashion. This saves tons of your $100/hour time from debugging, so that you can mess around having fun during the hours that clients are paying you to debug. It also strives to reduce the worldwide crisis of carpal tunnel syndrome, so it uses constructs such as this one to pack multiple function calls into one line, saving you the bother of typing more than you have to:
dbi_result_get_fields(result, "id.%i firstname.%s lastname.%s fractional_value.%f", &id, &firstname, &lastname, &floatval);
Driver interface:
The dynamic linking used by libdbi allows for driver authors to license their drivers however they please - they are not restricted to the GPL or LGPL. Drivers are easy to write, and require no special installation.
Error handling:
Instead of checking every single database call for errors, libdbi gives programmers the option of registering an error handler callback, similar to a signal handler. Because we know youll "forget" to check for errors otherwise :)
Convenience:
Spend your time writing clever code, not reinventing the wheel with your own single-use, #define-abusing, less featureful database interface.
libdbi implements a database-independent abstraction layer in C, similar to the DBI/DBD layer in Perl. Writing one generic set of code, programmers can leverage the power of multiple databases and multiple simultaneous database connections by using this framework.
The libdbi-drivers project maintains drivers for libdbi. Drivers are distributed seperately from the library itself.
There are currently drivers for MySQL, PostgreSQL, SQLite, and mSQL. More are on the way.
Enhancements:
- Support for a timezone suffix in time and date types was added.
- Error handling and error reporting were vastly improved.
- Some memory leaks were fixed.

libfirerpc is a library that provides an easy interface for C programs to make remote function queries via the XML RPC protocol.

It supports SSL/TLS, HTTP authentication, HTTP 1.1 persistent connections and pipelining. It also supports POST data compression via bzip2 and response compression via bzip2, gzip, deflate and compress.

Xrtti is an extended runtime type information for C++.

Xrtti is a tool and accompanying C++ library which extends the standard runtime type system of C++ to provide a much richer set of reflection information about classes and methods to manipulate these classes and their members.

Using Xrtti is as simple as running a tool (xrttigen) to process the class definitions of your program, compiling and linking the resulting generated code into your program, and then using the Xrtti API to reflect on the classes your program defines. You do not need to modify your class file definitions in any way to get the benefit of full reflection.
