Cannot find the constant XMLConstants.ACCESS_EXTERNAL_DTD in JDK 1.6

[Jack Lau]

Hi all,

The following code cannot be compiled in JDK 1.6 but can be compiled in JDK 1.7, do anyone know any other solution with the same function as the code provided which can be compiled in JDK 1.6 ?

TransformerFactory transFact = TransformerFactory.newInstance();
transFact.setFeature(XMLConstants.ACCESS_EXTERNAL_DTD, false);
Transformer trans = transFact.newTransformer(xsltSource);
trans.transform(xmlSource, result);

Error message:
Caused by: javax.xml.transform.TransformerConfigurationException: [ERR 0337] Cannot set the feature 'http://javax.xml.XMLConstants/property/accessExternalDTD' on this TransformerFactory.
at com.ibm.xtq.xslt.jaxp.AbstractTransformerFactory.setFeature(Unknown Source)

Thanks,
Jack

Can I use the code "f.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);" instead of "transFact.setFeature(XMLConstants.ACCESS_EXTERNAL_DTD, false);"? Is it the same purpose to prevent accessing external XML ?


TransformerFactory f = TransformerFactory.newInstance();
f.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
Transformer t = f.newTransformer();
t.transform(xmlSource, result);


Thanks,
Jack
