Cannot build because android-sparql uses XMLGregorianCalendar indirectly

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Created an Android project with Eclipse.
2. Copied the code from android-sparql in src
3. Imported openrdf-sesame-2.4.2-onejar.jar and slf4j-android-1.6.1-RC1.jar

What is the expected output? What do you see instead?
It does not compile since NativeLiteral imports LiteralImpl from 
openrdf-sesame, which uses XMLGregorianCalendar.

"The project was not built since its build path is incomplete. Cannot find the 
class file for javax.xml.datatype.XMLGregorianCalendar. Fix the build path then 
try building this project"

What version of the product are you using? On what operating system?

Sorry, it was my bad.

I was trying to deploy it in a 2.1 android (API version 7) and the 
XMLGregorianCalendar was not available till the version 8.
