Vitaliy Tkachenko created AXIS2-5753:
----------------------------------------
Summary: HTTP errors 500 and 400 are not reported appropriately on
WS call
Key: AXIS2-5753
URL: https://issues.apache.org/jira/browse/AXIS2-5753
Project: Axis2
Issue Type: Bug
Components: transports
Affects Versions: 1.7.1, 1.6.4
Environment: Win32x64, Tomcat7, ODE 1.3.6
Reporter: Vitaliy Tkachenko
Priority: Minor
On any WS call made in ODE (for example, I think the same is expected anyway
using the Axis2) all HTTP errors are reported appropriately e.g. 404 (Page Not
Found):
[2016-04-05 14:58:50,788] [ODEServer-18] [ERROR]

service 'http://ua007478/error404'.

But only incase of 2 errors 500 (Internal Server Error) and 400 (Bad Request)
the message is still parsed further which causes [WstxUnexpectedCharException:
Unexpected character '"'] of course as the message contains no message but HTTP

This behavior prevents user to proper analyze the cause of the problem with the
WS - it requires time and efforts to understand that the original problem is in
e.g. commonly used error 500 means the WS server has some teporarily problems.
I've found that the cause why Axis2 is doing this is the code in the
org.apache.axis2.transport.http.HTTPSender.handleResponse function (in the
1.6.4 or corresponding HTTPSender implementations in the 1.7.1) which derives
the logic if (statusCode == HttpStatus.SC_INTERNAL_SERVER_ERROR || statusCode
== HttpStatus.SC_BAD_REQUEST) allowing the message to be parsed (unless non
blocking API / transport flag is set) instead of throwing exception anyway. Is
there some real reason why exception isn't just thrown anyway including errors
500 and 400?
