Axis2 Retrying request

[Scott Sauyet <li...@sauyet.com>]

I'm having a problem using an Axis2 client to connect to a service that 
seems to have a real hiccup.  I'm trying to get the group that runs the 
service to fix the hiccup, but I would like to continue on while that 
happens, and I was wondering if anyone can suggest a way.

The problem is that the service fails to respond to the initial request, 
but will respond to a retry.  I noticed this when checking the WSDL in 
Firefox.  It won't load at first, but does load after a refresh.  I 
found that Opera loaded right away and IE and Safari wouldn't load at 
all.  (Safari had the most helpful response, saying that the server had 
dropped the connection.)  I used commons.httpclient to test and it posts 
an IO exception because the server failed to respond, then does a retry, 
which works fine.

I'm wondering if I can do some sort of automatic retry for such an 
exception in Axis2.

I don't know if this makes a difference, but the service is running in 
SSL (over HTTPS.)

Thanks for any suggestions you can offer,

It didn't actually solve my underlying problem, but I think I've found 
an answer to this question, although it involved more guess work than 
actual understanding.  I knew how to write a retry handler in 
HttpClient.  (http://tinyurl.com/2b3jek#Custom_exception_handler)  To 
connect it to Axis2, I tried this, and it seemed to work:

     stub._getServiceClient().getOptions().setProperty(
             HttpMethodParams.RETRY_HANDLER, MyHttpMethodRetryHandler);

where stub extends org.apache.axis2.client.Stub.  This was just 
guesswork.  But setting the log level to DEBUG, I could see a difference 
depending upon my retry handler.


Now back to the underlying issue.

Cheers,
