docx4j usa Xalan para convertir docx a HTML, y depende en gran medida de las extensiones Xalan Java para hacer el trabajo.¿Es posible llamar a una función de extensión de Java desde Xalan en Android?
Pero las extensiones Xalan no funcionan para mí en Android (trabajando con 4.0.3). LogCat dice:

¿Alguna idea de lo que es exactamente el problema y las soluciones?
¿Cómo declara y usa su función de extensión? –
Con xmlns: java = "http://xml.apache.org/xalan/java", algo así como llamando pública estática DocumentFragment myStaticMethod ( \t \t cadena s, \t \t NodeIterator b) –

tengo XSLT (no en Android) utilizando "Java: org.foo.Bar()" - de estilo y funciones que utilizo 'xmlns: java = "http://xml.apache.org/xalan/java" '. Después de publicar este comentario, puedo ver que el 'http: //' está oculto de tu comentario original ... puedes estar peleando contra un SecurityManager u otra cosa. * shrug * –
