\viewkind4\uc1\pard\lang2052\f0\fs20 Hi Arnaud,
\par
\par From your description, you're using WCF basic httpbinding to consume a JAVA webservice, however, you found the service call will always report error "underlying connection closed..." after the first method call, correct?
\par
\par As for this issue, based on my experience, it is likely the underlying soap request(from WCF to JAVA side) or the soap response(from JAVA side to WCF) doesn't quite meet the receiver's expected format. As you said the problem occur after the first method call, does it occur after you make the webservice call and haven't get the correcct response result. Or does it occur when you make the second webservice call?
\par
\par If the first call finish completely, then, is there any particular difference between the two ones or maybe the second one may take a long runtime time? If the problem can be isolated to method specific, we can then concentrate on that particular webmethod.
\par

\par Subject: WCF : Underlying connection was closed

\par Hi all,
\par
\par we meet a problem since we use WCF to consume java WebServices.
\par Often the first call works then the second raises the following error :
\par "The underlying connection was closed : "
\par
\par We use a basicHttpBinding over HTTPS to connect to WebService. The
\par configuration is the following
\par <binding name="SoapBinding" closeTimeout="00:01:00" openTimeout="00:01:00"
\par receiveTimeout="00:10:00" sendTimeout="00:02:00"
\par allowCookies="false"
\par bypassProxyOnLocal="false"
\par hostNameComparisonMode="StrongWildcard"
\par maxBufferSize="65536000" maxBufferPoolSize="524288"
\par maxReceivedMessageSize="65536000"
\par messageEncoding="Text" textEncoding="utf-8"
\par transferMode="Buffered" useDefaultWebProxy="true" >
\par \tab\tab\tab
\par \tab\tab <readerQuotas maxDepth="32" maxStringContentLength="8192"
\par maxArrayLength="16384"
\par maxBytesPerRead="4096" maxNameTableCharCount="16384" />
\par <security mode="Transport">
\par <transport clientCredentialType="None"
\par proxyCredentialType="None" realm="" />
\par <message clientCredentialType="UserName"
\par algorithmSuite="Default" />
\par </security>
\par </binding>\tab
\par </basicHttpBinding>
\par
\par We found some solution about the "KeepAlive" property of the generated proxy
\par but it concerns "standard" webservice. We don't know how to reproduce this on
\par WCF client.
\par
\par Is there a solution with Binding configuration or with code ?
\par
\par Thanks
\par
