Java og xml

Umiddelbart tror jeg at du skal prøve at skifte XML parser implementation.

Java 1.4.x : prøv og fjern Saxon

Java 1.3.x : prøv og fjern Saxon og tilføj Xerces eller Crimson

altså fjerne jar filen med saxon fra mit projekt ??

jeg kan nemlig ikke bare fjerne saxon.jar filen, da den bruges af andre klasser. Er der andre muligheder ?

Det var det jeg tænkte på.

Bruger de andre klasser Saxon specifikke klaser/metoder ?

Har du nyeste version af Saxon ?

Hm.

Det er et kendt problem !

ja, jeg fandt også de artikler.....

kan jeg ikke bruge jdom i stedet for ?

Jeg fandt dette eksempel som bruger xerces, men den giver samme fejl......

har fundet en løsning....


System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl");

så virker skidtet.....
