Hi,
I'm working on an article about compiling java-sources to c++.
I'm interessted if someone would use this to write a program in java (and
the good IDE's available for java) and convert this to C++ to get the
advantages and speed of this language.

This approach has no advantage over the current compilers/jvms which
generate assembler. It is just one extra step.

Hand converting critical code to C++ can help in some circumstances,
but then the data structures bear little resemblance to their Java
counterparts, there is no Java-style safety net, you handle
allocation/destruction manually etc. It has to be tweaked for a
particular platform. It uses the native GUI rather than Swing....

Did you try GNU gcj? This software is the Java frontend of the GNU
Compiler Collection, so you can mix java code with C++, C and all other
GCC supported languages.
