Subject HTTP 502 Proxy Error in Axis 1.3
Date Fri, 16 Nov 2007 19:03:38 GMT
Hi,

 

We have a webservice which is using Axis 1.3.

 

There are some clients using our webservices.  One of the clients
reported that he is getting a HTTP 502 Proxy Error intermittently when
accessing our webservices.

 

Does anyone face this problem before or know why this is occurring?  Is
there any solution for this issue?

 

Here is the stack trace of the error.

 

AxisFault

 faultCode: {http://xml.apache.org/axis/}HTTP

 faultSubcode:

 faultString: (502)Proxy Error

 faultActor:

 faultNode:

 faultDetail:

        {}string: return code:  502

&lt;!DOCTYPE HTML PUBLIC &quot;-//IETF//DTD HTML 2.0//EN&quot;&gt;

&lt;html&gt;&lt;head&gt;

&lt;title&gt;502 Proxy Error&lt;/title&gt;

&lt;/head&gt;&lt;body&gt;

&lt;h1&gt;Proxy Error&lt;/h1&gt;

&lt;p&gt;The proxy server received an invalid^M

response from an upstream server.&lt;br /&gt;^M

The proxy server could not handle the request &lt;em&gt;&lt;a
href=&quot;/webservices/ResponsysWS&quot;&gt;POST&amp;nbsp;/webservices/
ResponsysWS&lt;/a&gt;&lt;/em&gt;.&lt;p&gt;

Reason: &lt;strong&gt;Error reading from remote
server&lt;/strong&gt;&lt;/p&gt;&lt;/p&gt;

&lt;hr&gt;

&lt;address&gt;Apache/2.2.4 (Unix) mod_ssl/2.2.4 OpenSSL/0.9.7a Server
at ws1.responsys.net Port 80&lt;/address&gt;

&lt;/body&gt;&lt;/html&gt;
