Re: Problem calling Web Service -> HTTP 503 error

Tue, 28 Jul 2009 10:30:56 -0700 

Hi Andreas,
thank you very much! But I have at the moment not the possiblity to look at the server logs and I do not really know how to trace on my client. I've looked in the axis2.xml for logging options but found nothing that helped. 

Can you give me a tip how to trace on my client?

Jan,

This is what happens in this case:

1. Your client sends a request to the server.
2. That request is rejected by the server and it sends back an HTML
error page (instead of a SOAP fault). The particularity here is that
the error page is XHTML and contains a reference (system ID) to the
corresponding DTD.
3. Axis2 receives that response and tries to parse it (using StAX).
4. The StAX parser, seeing the reference to the DTD, tries to load
that document (from the address you see in the error message:
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd).
5. The W3C site probably has a policy in place that blocks access to
the DTD to some User-Agents. They do this to protect themselves
against libraries/products that repeatedly attempt to download the
same DTD (or XML schema) without apparent need for it.
6. StAX gets back an HTTP error 503 (Service unavailable) and reports
that as an exception. This is what you see in the logs.

Conclusion:

- Obviously there is an issue in Axis2: we should not allow the StAX
parser to download DTDs from foreign sites. Note that DTDs are never
used in SOAP messages.
- In your case, the 503 error from www.w3.org obscures the actual
error which occurs in your server. Since you are using HTTPS, probably
the only way to find out what happens is to look at the server logs or
increase the log level of the client (to DEBUG or even TRACE) to see
at least the HTTP status line received from the server.

Regards,

Andreas

Hi,


I have a problem with a web service. I wrote a axis2 web service  
client

and

it worked with a Web Service on "server 1" . Now I tried to use  
the same

web
service but on another server ("server 2").

The axis method sendRecieve throws an axis fault and the error is:

org.apache.axis2.AxisFault: java.lang.RuntimeException: [was class
java.io.IOException] Server returned HTTP response code: 503 for
URL:http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430)
.......
.....



The URL of the web service on "sever 2" is https. I have no idea  
how to

solve the problem.

Any ideas?
Thanks in advance!


JF
