Policy with 'Layout' 'Lax' having no subelements leads to a
NullPointerException in PolicyEngine
------------------------------------------------------------------------------------------------
Key: RAMPART-143
URL: https://issues.apache.org/jira/browse/RAMPART-143
Project: Rampart
Issue Type: Bug
Components: rampart-policy
Affects Versions: 1.3
Environment: Windows Vista 32bit(XP32bit, Java 1.4.2, Eclipse 3.3
Reporter: Heinz Zerbes
I'm using a quit simple policy with Rampart. The Element 'Layout' having
subelement 'Lax' wich itself has no more subelements or attributes, leades to a
NullPointerException in PolicyEngine.processOperationElement:164. THe fact that
'Lax' has no subelements is not checked, thus the usage of this null
(sub)element leads to a NullPointerException. The specification says explicitly
that 'Lax' can be empty.
The code from PolicyEngine.java:
private static PolicyOperator processOperationElement(
OMElement operationElement, PolicyOperator operator) {
if (Constants.TYPE_POLICY == operator.getType()) {
Policy policyOperator = (Policy) operator;
OMAttribute attribute;
OMNamespace namespace;
QName key;
// <<<<<<<<<<<<<<<<<< my comment: operationElement ist null because of missing
subelement, tus next statement fails >>>>>>>>>>>>
for (Iterator iterator = operationElement.getAllAttributes();
iterator
.hasNext();) {
attribute = (OMAttribute) iterator.next();
namespace = attribute.getNamespace();
if (namespace == null) {
key = new QName(attribute.getLocalName());
} else if (namespace.getPrefix() == null) {
key = new QName(namespace.getNamespaceURI(), attribute
.getLocalName());
} else {
key = new QName(namespace.getNamespaceURI(), attribute
.getLocalName(), namespace.getPrefix());
}
policyOperator.addAttribute(key, attribute.getAttributeValue());
}
}
OMElement childElement;
