Jeff Thomas updated AXIS2-6091:
-------------------------------
Description:
I am testing upgrading to Axis2 2.0.0 (and associated Axiom 2.0.0 upgrade).
I am seeing a processing error when a HTTP 404 is received by an
OutInAxisOperationClient when an endpoint is not available (target application
not running) but the Tomcat instance is running.
The returned response obtained from the input-stream is:
{code:java}
<!doctype html>
<html lang="en">
<head>
<title>HTTP Status 404 – Not Found</title>
<style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1,

<h3>Apache Tomcat/11.0.5</h3>
</body>
</html> {code}
The stacktrace for the fault is as follows:
{code:java}
org.apache.axis2.AxisFault: org.apache.axiom.core.stream.StreamException:

{code}
Ultimately it lands in this chain:
* OutInAxisOperationClient#processResponse ->
* TransportUtils#createSoapMessage ->
* ...
* TransportUtils#createDefaultDocumentElement
It lands here because it cannot find any configured MessageBuilder for the
content-type "text/html".
Here it comes in this code:
{code:java}
private static OMElement createDefaultDocumentElement(MessageContext msgContext,
InputStream inStream,
String type) {
OMElement documentElement;
if (msgContext.isDoingREST()) {
if (log.isDebugEnabled()) {
log.debug("Could not find a Builder for type (" + type + "). Using
REST.");
}
OMXMLParserWrapper builder = BuilderUtil.createPOXBuilder(inStream,
null);
documentElement = builder.getDocumentElement();
} else {
// FIXME making soap defualt for the moment..might effect the
// performance
if (log.isDebugEnabled()) {
log.debug("Could not find a Builder for type (" + type + "). Using
SOAP.");
}
String charSetEnc = (String) msgContext
.getProperty(Constants.Configuration.CHARACTER_SET_ENCODING);
SOAPModelBuilder builder = BuilderUtil.createSOAPModelBuilder(inStream,
charSetEnc);
documentElement = builder.getDocumentElement();
}
return documentElement;
} {code}
The '{{{}isDoingRest{}}}' returns _false_ and the {{contentType}} is
'text/html' and encoding 'UTF-8'.
The exception is thrown trying to parse the HTML to SOAP:
{code:java}
documentElement = builder.getDocumentElement(); {code}
Possibly this is also related to the code in {{HTTPSender#send}} for handling
404/500 HTTP responses?
{code:java}
else if (statusCode == HttpStatus.SC_INTERNAL_SERVER_ERROR
|| statusCode == HttpStatus.SC_BAD_REQUEST ||
statusCode == HttpStatus.SC_NOT_FOUND) {
processResponse = true;
fault = true;
}{code}
We would really like to get off our custom forks of Axis2/Axiom/Rampart - or at
least as close to the current release as possible but this is currently a
blocker for us. Our monitoring continuously polls endpoints that may or may
not be available and this generates loads of errors / stacktraces in our logs.
I enabled the following parameter as a test to use the "UnknownBuilder"
{code:java}
<parameter name="useDefaultFallbackBuilder">true</parameter> {code}
I didn't get the Axiom exception, but it only leads to a follow-up exception:
{code:java}
java.lang.IllegalArgumentException: The MessageContext does not have an
associated SOAPFault.

{code}
So all in all, if I am not analyzing this incorrectly, Axis2 doesn't seem to be
handling the case where an endpoint returns a 404/500 response that is HTML and
not SOAP (and probably other HTTP status as well (400 BAD_REQUEST, 401
UNAUTHORIZED, 403 FORBIDDEN, 418 (I am a teapot! :P), ...).
