[xmlvm-users] Using XMLVM to generate a Cocoa library

[Ian F. <ifr...@gm...>]

Hello,

I have been experimenting using XMLVM to generate an iPhone compatible
library from java source meant to be the API on the Android side.  I'm not
trying to generate a full app for the iPhone using XMLVM, just an API
library.

I generated the objective C files, built a library using those files and
your compatability files for objective C.  Now I'm trying to use that
library in a native iPhone application.

My problem is that the implementation categories don't seem to be referenced
properly as I see two things:

1 - warning like this:

: warning: incompatible Objective-C types 'struct java_lang_String *',
expected 'struct java_lang_String *' when passing argument 1 of
'__init_com_newsdart_client_NDApi___java_lang_String:' from distinct
Objective-C type


2 - runtime selector exception on this line in the generated code for one of
my classes:


    [((java_lang_Object*) _r2.o) __init_java_lang_Object__];

The object it is operating on is an object I instantiated in the native
iPhone code using:

[[class alloc] init]

This class had a constructor initializer of a String object in the original
java code.  It was translated into the init call you see in #1 above.  The
code above in #2 is near the top of that function.

It seems that for some reason the object that I'm creating is created using
the native NSObject, and not the NSObject modified using categories by
java_lang_Object.  I'm confused as to how I could control this as the steps
I went through were pretty straight forward.

Is there some compiler option needed for implementation categories to work
correctly? (either for the library I'm creating or native application using
the library?

I think my problem must be pretty basic.

Best Regards,

Ian
