Java from VC++

[ToSam]

I am writing a VC++ program that has to fetch a Java source file,
compile it with a Java compiler, execute it at runtime, and return the
result objects back to VC++. Do you know of any sample codes to
illustrate how that works, or any suggestions?

There are some things that you can actually do in C++ (fetch a file,
probably - what exactly do you want to do?), execute a program
( std::system("path/to/javac.compiler") or std::exec* functions ),
and IIRC the Java file that is produced can be run again using
a similar std::system command.

I'm not sure what you mean with the "result objects". The closest
thing to a result object in C++ is the single int returned from
int main( ). But I could imagine the Java program producing an
output file. You could read that back in C++. In fact, since Java
sources are just text, and C++ can manipulate text, you could also
modify the Java source text before you compile it, such that the
output objects are stored to a file.

There are no functions in the C++ standard library
whose names begin with 'exec'.
