Re: [xmlvm-users] Using the posix backend

[Arno P. <ar...@pu...>]

look at src/android2iphone to see which Android classes can be 
cross-compiled to iOS.

As for standard J2SE API, XMLVM cross-compiles Apache Harmony. We have 
deemed some classes as not required for iOS. We call these "red 
classes". You can see a list of those classes in xmlvm/lib/redlist.txt. 
If you happen to need a class that is on the red list, simple remove it 
in redlist.txt.

You ran into an unimplemented native method. Although we cross-compile 
Harmony, some classes require access to the native layer (in your case 
you are trying to create a socket). That code is in 
xmlvm/src/xmlvm2c/lib/native. You would have to provide a C 
implementation for the API you need.
