[jira] Created: (MUSE-146) NotificationProducer unable to send
complex type elements
NotificationProducer unable to send complex type elements
---------------------------------------------------------
Key: MUSE-146
URL: http://issues.apache.org/jira/browse/MUSE-146
Project: Muse
Issue Type: Bug
Environment: Windows XP SP2, Apache 2.2, Tomcat 5.5, Muse 2.0.0, Eclipse 3.2.1, XmlBeans 2.2.0
Reporter: Vinh Nguyen
Assigned To: Dan Jemiolo
Sending a notification containing a complex element doesn't seem to work. It only works for an element containing a simple string message. I'm using XmlBeans for conversion between xml schemas and java objects. Using the code below, the notification does not appear to be sent, nor do any errors get thrown in the process.
BoxDocument doc = BoxDocument.Factory.newInstance();
BoxType type = doc.addNewBox();
type.setWidth(BigInteger.valueOf(123));
type.setHeight(BigInteger.valueOf(123));
QName qname = new QName(NAMESPACE_URI, "MyMessage", PREFIX);
Element payload = XmlUtils.createElement(qname, XmlUtils.getFirstElement((Document)doc.getDomNode()));
NotificationProducer np = ...
np.publish(TOPIC_NAME, payload);
Here is the XML from doc.xmlText():
<box:Box xmlns:box="http://cisco.com/musebox/schemas/box"><box:width>123</box:width><box:height>123</box:height></box:Box>

Okay, using my latest build, I get the following trace when I send a message payload that doesn't use prefixes:

This is very weird. The NotificationMessage element is removed! the <wsnt:NotificationMessage part is erased, but the namespace declarations remain as text, and the closing bracket (>) has been normalized to the proper character code (as if it were text data). When you put a prefix back in, the NotificationMessage element remains.
Because the NotificationMessage element is removed (and its children become Notify's children), the parser gets screwed up.
I honestly don't know what to do about this, because that server-side logging (LoggingUtils.logMessage()) happens right after the XML is received from Axis2. I'm guessing it may be an Axis2 problem, but I will doublecheck using our new "mini" platform tonight.

It's not Axis2, it's Xerces:
2006-11-27 18:46:15 StandardWrapperValve[ApacheMuseServlet]: Servlet.service() for servlet ApacheMuseServlet threw exception
java.io.IOException: Element or attribute do not match QName production: QName::=(NCName':')?NCName.

Xerces and default namespaces in DOM L2 do not jive. The only info I could find on this online was from the Cocoon project, which was not too helpful. I'm going to resolve this by adding an item to our "troubleshooting" section.

[jira] Updated: (MUSE-146) NotificationConsumer creates empty
NotificationMessage array when no XML prefixes present
Posted by "Dan Jemiolo (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/MUSE-146?page=all ]
Dan Jemiolo updated MUSE-146:
-----------------------------
Component/s: Core Engine - Routing and Serialization
WSN NotificationConsumer
Summary: NotificationConsumer creates empty NotificationMessage array when no XML prefixes present (was: NotificationProducer unable to send complex type elements)
Fix Version/s: 2.1.0
Affects Version/s: 2.0.0
Priority: Minor (was: Major)
The root of this problem is actually on the consumer side. The ReflectionMessageHandler, when using NotificationMessageSerializer to parse an array of NotificationMessage elements, returns an empty array if the message payload does not use XML prefixes for its namespaces. The call does not fail with a runtime exception, NPE, etc. - it simply does not parse any messages, and so the array that the notify() implementation iterates over is zero-length. If prefixes are used, the messages are parsed properly.
If I cannot determine the cause of this by EOD tomorrow, it will have to wait for 2.2 and we will make an entry in the troubleshooting section of the manual.
