Tak jak vypada kod, ktery to NPE vyhodil ...
jedna se o nasledujici metody:
at org.apache.commons.digester.Digester.getXMLReader(Digester.java:891)
at org.apache.commons.digester.Digester.parse(Digester.java:1591)
Letmim pohledem do techto metod (verze 1.8, netusim, kterou pouzivate vy) bych
rekl ze ten kdo je psal je trochu cune,
ale nema se tam moc co podelat. Jedina moznost je, ze behem vytvareni SAX
parseru to vyhodi vyjimku, kterou autor vtipne
zachyti a vrati null, coz muze vest k vami popisovanemu chovani.
Takze si zapnete logovani tak, aby to pro digester vypisovalo alespon ERRORy a
pak by se vyjimka mela zobrazit ...
Hodne stesti!

// There is no portable way to specify the location of

properties.put("schemaLanguage", schemaLanguage);
}

} else {
