NullPointerException in XMLbeans code generation with xmime:contentType
-----------------------------------------------------------------------
Key: AXIS2-774
URL: http://issues.apache.org/jira/browse/AXIS2-774
Project: Apache Axis 2.0 (Axis2)
Type: Bug
Components: databinding
Versions: 1.0
Reporter: Kent Tong
In the org.apache.axis2.xmlbeans.CodeGenerationUtility class, the
findBase64Types() method (as shown below) contains a bug: It is calling
getDocumentElementName() on the outer type but this method works on the
"document type" only, otherwise it will return null:
if (sType.getContentType() == SchemaType.SIMPLE_CONTENT &&
sType.getPrimitiveType() != null) {
if
(Constants.BASE_64_CONTENT_QNAME.equals(sType.getPrimitiveType().getName())) {
outerType = sType.getOuterType();
//check the outer type further to see whether it has the
contenttype attribute from
//XMime namespace
SchemaProperty[] properties = sType.getProperties();
for (int j = 0; j < properties.length; j++) {
if
(Constants.XMIME_CONTENT_TYPE_QNAME.equals(properties[j].getName())) {
base64ElementQNamesList.add(outerType.getDocumentElementName());
break;
}
}
}
}
The result is, the base64 qname list will only contain null's as its elements.
This will later cause the
AxisServiceBasedMultiLanguageEmitter.getBase64Elements() to fail. The stack
trace is:
