Description

When I set endpointName to a simple string without prefix in an endpoint definition I get a Nullpointer exception in DOMUtils. This is probably easy to fix.

public static String getNamespace(Element el, String pre) {
NamedNodeMap atts = el.getAttributes();
for (int i = 0; i < atts.getLength(); i++) {
Node node = atts.item;
String name = node.getLocalName();
String pre2 = node.getPrefix();
if (pre.equals(name) && "xmlns".equals(pre2))

{ return node.getNodeValue(); }

else if (pre.length() == 0 && "xmlns".equals(name) && pre2.length() == 0)

{ <======= The error happens at pre2.length when pre2 is null return node.getNodeValue(); }

}

I have attached the stack trace:
