Herwig David commented on SYNAPSE-675:
--------------------------------------
Hi Hiranya,
I have changed the web service to return less data and the response now arrives
the client.
But with another web service I have still an issue with the response.
synapse.xml:
...
<!-- define a reuseable endpoint definition -->
<sequence name="_ProxyOut">
<log level="full"/>
<send/>
</sequence>
<sequence name="WS7X4PilOrder_ProxyIn" trace="enable">
<send>
<endpoint>
<address uri="https://app02-srapme.medical-
intern.com:8443/axis2/services/WS7X4PatientInfoLeafletOrder"/>
</endpoint>
</send>
</sequence>
<proxy name="WS7X4PatientInfoLeafletOrder" transports="https">
<publishWSDL key="WS7X4PilOrder_ProxyWsdl"/>
<target inSequence="WS7X4PilOrder_ProxyIn" outSequence="_ProxyOut">
</target>
</proxy>
...
I have changed the client coding by adding additional timeout parameter and
retry handler configution. See below.
Also I have set the parameters SO_TIMEOUT and CONNECTION in the axis2.xml in
synapse conf directory and the axis2.xml on tomcat installation for the web
service.
Instead of the 'InputStream cannot be NULL' message I now get the axis fault
'The server bro02-srapme.medical-intern.com failed to respond'.
When calling the web service directly on the tomcat the response takes about 5
seconds. So timeout shouldn't be the issue here.
I have attached the synapse log files but do not see an issue there. Alsp the
log files on tomcat do not contain a fault behavior.
I assume the amount of data processed by synapse is the issue here.
Thanks and regards,
Herwig

> Hi,
> When calling one of my web services via synapse proxy service I get an
> AxisFault 'InputStream cannot be NULL'.
> When calling the web service directly on the tomcat I get the response
> without problems.
> Both are https requests.
> Searching the internet I have found two solutions to increase the timeout:
> 1st: setting the client options:
> "
> ServiceClient client = stub._getServiceClient();
>
> client.engageModule("addressing");
> client.engageModule("rampart");
> // get option object
> Options options = client.getOptions();
> // set username / password
> options.setProperty("user", TestClient.userAlias.toString());
> options.setProperty("encryptionUser", TestClient.serverAlias);
> options.setTimeOutInMilliSeconds(1200000);
>
> //setting created option into service
> client.setOptions(options);
> "
> 2nd: Increasing the timeout in synapse.xml

> Unfortunately this doesn't help.
> I assume that the connection issue is on synapse side.
> Is there another way to increase the timeout in synapse when using as proxy
> service?
