[jira] Created: (CXF-1724) Nullpointer error in DOMUtils
Nullpointer error in DOMUtils
-----------------------------
Key: CXF-1724
URL: https://issues.apache.org/jira/browse/CXF-1724
Project: CXF
Issue Type: Bug
Affects Versions: 2.1.1
Reporter: Christian Schneider
Fix For: 2.1.2
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(i);
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:

[jira] Updated: (CXF-1724) Nullpointer error in DOMUtils
Posted by "Dave Leatherdale (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CXF-1724?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dave Leatherdale updated CXF-1724:
----------------------------------
Attachment: CXF-1724.diff
Added a null check to the part of code in question. Not sure that a blank string will ever be returned but i coded to accept with null or a blank string. Added some javadoc and renamed most of the variables so they make more sense to me.
