Hello!



I run this method:

public String getDocumentAsString(boolean includeInternalDTD) throws IOException, LibraryException
{
StringWriter sw = new StringWriter();
((TXDocument)_document).setPrintInternalDTD(includeInternalDTD);
((TXDocument)_document).printWithFormat(sw);

return(sw.toString());
}



And get this error:


com.ibm.xml.parser.LibraryException: com.ibm.xml.parser.TXDocument#printWithForm
at(): Unexpected Exception: java.lang.NullPointerException
at com.ibm.xml.parser.TXDocument.printWithFormat(TXDocument.java)
at com.ibm.xml.parser.TXDocument.printWithFormat(TXDocument.java)
at com.my.test.xml.XMLCompiler.getDocumentAsString(XMLCompil
er.java:294)



Does any one know why?


Best regards


Fredrik
