[jira] Updated: (WSCOMMONS-32) Call to
OMSourcedElementImpl.getXMLStreamReaderWithoutCaching() returns an
XMLStreamReader WITH caching
[ http://issues.apache.org/jira/browse/WSCOMMONS-32?page=all ]
Lakshmi Chaparala updated WSCOMMONS-32:
---------------------------------------
Attachment: DataObjectOMDataSource.java
Our implementation is based off the OMDataSourceTest.java code from Axiom. Our custom OMDataSource simply serializes a Byte array. The source code is attached. Our DataObjectOMDataSource is used in our code as follows:
private OMElement getQueryResults(SNLModel snlModel, Vector requiredAttrs , IDataObjectProcessor processor) {
//This populates the member ByteArrayOutputStream os with xml
getDataObjectxml(snlModel, requiredAttrs, processor);
//***** OMDataSource implementation **********
String dataObjectSetNamespaceURI = "http://www.issinc.com/gateway/domain";
OMFactory omFactory = OMAbstractFactory.getOMFactory();
OMNamespace omNamespace = omFactory.createOMNamespace(dataObjectSetNamespaceURI, "");
OMElement dataObjectSetElement = new OMSourcedElementImpl("DataObjectSet",
omNamespace,
new OMLinkedListImplFactory(),
new DataObjectOMDataSource(os.toByteArray()));
return dataObjectSetElement;
}
If there is something incorrect with this implementation, please let us know. The only way we could get it to work was to eliminate the OMSourcedElementImpl derived getXMLStreamReaderWithoutCaching() method.

> I used Axis2's OMSourcedElementTest.java as an example of how to use a custom OMDataSource. In this case you construct an OMSourcedElementImpl class and give it your custom OMDataSource. When the service implementation class the constructed OMSourcedElementImpl and Axiom streams it out, the OMSerializerUtil class makes a call to OMSourcedElementImpl.getXMLStreamReaderWithoutCaching(), which returns an XMLStreamReader WITH caching. This sends the code down an execution path that fails to stream the OMSourcedElementImpl because it looks for OMElement objects that aren't there.
