Using XMLVM: Android to iPhone

Related to this question: Use with XMLVM to convert android app to iphone app

XMLVM comes with several demo projects which I assume must work perfectly for some people. I've been running into snags and can't find very much documentation to help me. I've been following the documentation from the xmlvm site: http://www.xmlvm.org/documentation/manual.pdf

My story so far (skip down a bit for my current problem)

First of all, this is a Windows XP SP3 32-bit system.

I installed Android SDK and downloaded and installed SDK Platform Android 1.5, 1.6, 2.2, 2.3.3, 3.0.

I checked out XMLVM and built it using ant. So far, so good. (Section 1.3 on the manual)

I tried building the android demo projects (xokoban, helloworld, afireworks). Each one fails, complaining that it can't find my Android SDK. It's been properly set up as described in the manual, so I open up the build.xml files to see what they're actually looking for... they're looking for "$sdk$/tools/android". Well, the android sdk has an "android.bat" in the right spot, so I copy the batch file as just "android" and the builds run fine now.

My current problem:

Now I invoke XMLVM using the line

java -Xmx1G -jar c:\xmlvm\xmlvm.jar --in=/demo/android/hello开发者_如何学JAVAworld --target=android-on-iphone --app-name=bleh

And I get the error

Error: Unknown target: android-on-iphone

So I try the same line, but with --target=iphone

This returns the error

Exception in thread "main" java.lang.reflect.InvocationTargetException

Caused by: java.lang.NullPointerException
    at org.xmlvm.util.FileSet$3.hasNext(FileSet.java:98)
    ...

In a nutshell, I'm stuck and I can't even get through the demo. Halp.

RTFM.......... In fact, this part was highlighted in the "related post":

In section 2.2.3 of the manual, it clearly states that the makefile will only work on a Mac OS platform with the Xcode IDE. I guess I really can't start on this project until I get the mac.
