Subject: XMLSchema bug
To: [EMAIL PROTECTED]
hallo,
yesterday I found one bug in org.apache.ws.commons.schema.SchemaBuilder class
(vesrsion 1.0.3). The problem occures with schemas having „redefine"
elements, seems that nobody before have tested this class with redefine
case. The code „redefine.schemaTypes.collection.put(xx, yyy)" allway throws
NullPointerException.
private XmlSchemaRedefine handleRedefine(XmlSchema schema,
Element redefineEl, Element
schemaEl) {
XmlSchemaRedefine redefine = new XmlSchemaRedefine();
redefine.schemaLocation =
redefineEl.getAttribute("schemaLocation");
//redefine has no such thing called a namespace!
redefine.schema =
resolveXmlSchema(null,redefine.schemaLocation);
for (Element el = XDOMUtil.getFirstChildElementNS(redefineEl,
XmlSchema.SCHEMA_NS)
; el != null;
el = XDOMUtil.getNextSiblingElementNS(el,
XmlSchema.SCHEMA_NS)) {
if (el.getLocalName().equals("simpleType")) {
XmlSchemaType type =
handleSimpleType(schema, el, schemaEl);
redefine..collection.put(type.getQName(),
type);
redefine.items.add(type);
} else if (el.getLocalName().equals("complexType")) {
XmlSchemaType type = handleComplexType(schema, el,
schemaEl);
redefine.schemaTypes.collection.put(type.getQName(),
type);
redefine.items.add(type);
} else if (el.getLocalName().equals("group")) {
XmlSchemaGroup group = handleGroup(schema, el,
schemaEl);
redefine.groups.collection.put(group.name, group);
redefine.items.add(group);
} else if (el.getLocalName().equals("attributeGroup")) {
XmlSchemaAttributeGroup group =
handleAttributeGroup(schema, el, schemaEl);
redefine.attributeGroups.collection.put(group.name, group);
redefine.items.add(group);
} else if (el.getLocalName().equals("annotation")) {
XmlSchemaAnnotation annotation = handleAnnotation(el);
redefine.setAnnotation(annotation);
}
// }
}
return redefine;
}
The reason is „schemaTypes" - null: it is not instanciated in
XmlSchemaRedefine constructor.
I have changed constructor with thsi code:
public XmlSchemaRedefine() {
items = new XmlSchemaObjectCollection();
attributeGroups = new XmlSchemaObjectTable();
groups = new XmlSchemaObjectTable();
schemaTypes = new XmlSchemaObjectTable();
}
now it works for as.
