IOException in: R( /) Socket closed

[Jerome Destarac]

hi,

i've this error ;

 400 R( /) null
 IOException in: R( /) Socket closed

i use apache-tomcat server  with a Vb client. i have  these properties to my client
Connector.Property("EndPointURL") = "https://server:443/soap/servlet/rpcroute
Connector.Property("UseSSL") = True
Connector.Property("SSLClientCertificateName") = "my certificate"
etc ...

on the server :
<Connector className ="org.apache.tomcat.service.PoolTcpConnector">    
                      <Parameter name="handler" value 
="org.apache.tomcat.service.http.HttpConnectionHandler"/>    
                      <Parameter name="port" value="443"/>    
                      <Parameter name="socketFactory" 
value="org.apache.tomcat.net.SSLSocketFactory" />    
                      <Parameter name="keystore" value="c:\keystore\my.keystore" />    
                      <Parameter name="keypass" value="pwd"/>    
                      <Parameter name="clientAuth" value="false"/>    
</Connector> 

i think i export corectly the client certificate in the server keystore. i don't know 
why it doesn't work !!!
an idea ???

thanks,
jerome
