Hi,
thanks for sharing your ideas ...

Instead, i found the mapping from IDL to java looks missing something:
1. the mapped Java classes contains less information than the IDL, By using
the Java 5 annotations will solve this problem, and we can even write no IDL
at all, and simply writing the Java classes, and using a tool to generate
the IDL if neccessary.
We cannot use Java 5 features because we have to be compatible with
older versions.
2. the Out/In Out parameter mapping is something strange. I think using a
OutHolder<T> or InOutHolder<T> will be more clear
see above
3. No Service is mapped, this require the queryInterface called frequently.
I think a Service can be mapped to an interface which may extends other
interface or aggregate optional interface inside.
that 's true for old services but not for the new UNO ease of use
extensions. See
http://udk.openoffice.org/common/man/draft/multinherit.html for more
details.
And more, i think there should be a util to generate the POJO mapping from
exists IDL(Its better to include the documents in Java).
i am not sure if I understand you but with the new javamaker tool we
generate directly Java class files from the type library. The type
library is currently necessary for the UNO runtime to get the necessary
type information (Basic, C++). Yes we have thought about a TypeProvider
who works on IDL or better on Java class files directly but haven't
implement it until now.
