È possibile chiamare una funzione di estensione Java da Xalan su Android?

docx4j utilizza Xalan per convertire docx in HTML e fa molto affidamento sulle estensioni Java Xalan per eseguire il lavoro.È possibile chiamare una funzione di estensione Java da Xalan su Android?

Ma le estensioni Xalan non funzionano per me su Android (funziona con 4.0.3). LogCat dice:

Qualche idea su quale sia esattamente il problema e soluzioni alternative?

Come stai dichiarando e utilizzando la funzione di estensione? –

Con xmlns: java = "http://xml.apache.org/xalan/java", qualcosa come chiamando public static DocumentFragment myStaticMethod ( \t \t String s, \t \t NodeIterator b) – JasonPlutext

ho XSLT (non su Android) con "Java: org.foo.Bar()" - le funzioni di stile e io uso 'xmlns: java = "http://xml.apache.org/xalan/java" '. Dopo aver postato questo commento, posso vedere che 'http: //' è nascosto dal tuo commento originale ... potresti essere in lotta contro un SecurityManager o qualcos'altro. * scrollando le spalle * –

Android include la propria copia di alcune librerie XML di Apache. Se desideri includere le tue versioni nella tua app, la soluzione migliore è riconfezionarla utilizzando lo instructions here.

Ho riconfezionato varie cose (ad esempio javax.xml.bind), ma non vi è alcun suggerimento che questo sia il problema qui, c'è? – JasonPlutext

È possibile chiamare una funzione di estensione Java da Xalan su Android?
