AW: sessions and client config

[Oliver Adler]

Hi,

the simple session handler adds the session  id  only if there exists the right 
property in MessageContext. If this property doesn't exists the session header will 
not be craeted.

 

 

Hi,

I fiddled around with session management in Axis for a few days now and I
encountered some problems, mainly related to the client configuration.
The following explanation is quite long but I think necessary to get the
whole background.

OK

First I tested the example test.session.TestSimpleSession and it worked
fine.

Then I tried to make my service session enabled, adding a method that works
more or less similar to the one in the example (just for testing purposes).
The server part is generated with the Java2WSDL and WSDL2Java tools and I
added the SimpleSessionHandler to the server .wsdd like that

...
<handler name="SimpleSessionHandler"
type="java:org.apache.axis.handlers.SimpleSessionHandler"></handler>
        <!-- Services from FMConnectorService WSDL service -->
        <service name="FMConnector" provider="java:RPC">
                <requestFlow>
                <handler type="SimpleSessionHandler"/>
                        <handler type="soapmonitor"/>
        </requestFlow>
        <responseFlow>
                <handler type="SimpleSessionHandler"/>
                        <handler type="soapmonitor"/>
        </responseFlow> 
...

Session management on the server seems to work because I see (in the
SOAPMonitor) a response with session ID

        <?xml version="1.0" encoding="UTF-8"?>
        <soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
         <soapenv:Header>
          <ns1:sessionID soapenv:actor="" soapenv:mustUnderstand="0"
xsi:type="xsd:long"
xmlns:ns1="http://xml.apache.org/axis/session";>6254954670844961902</ns1:sess
ionID>
         </soapenv:Header>
         <soapenv:Body>
          <ns2:commitReceiptResponse
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:ns2="FMConnector">
           <commitReceiptReturn
xsi:type="xsd:string">org.apache.axis.session.SimpleSession@87e704
1</commitReceiptReturn>
          </ns2:commitReceiptResponse>
         </soapenv:Body>
        </soapenv:Envelope>

My client app is simple and again a modification of the
SimpleSessionHandler.

        import org.apache.axis.client.Service;
        import org.apache.axis.client.Call;
        import org.apache.axis.configuration.XMLStringProvider;


        public class TestClient {
           
             static final String clientWSDD =
                    "<deployment xmlns=\"http://xml.apache.org/axis/wsdd/\";
" +
       
"xmlns:java=\"http://xml.apache.org/axis/wsdd/providers/java\";>\n" +
                    " <handler
type=\"java:org.apache.axis.handlers.SimpleSessionHandler\" " +
                              "name=\"SimpleSessionHandler\"/>\n" +
                    "<globalConfiguration>\n" +          
                    "  <requestFlow><handler
type=\"SimpleSessionHandler\"/></requestFlow>\n" +
                    "  <responseFlow><handler
type=\"SimpleSessionHandler\"/></responseFlow>\n" +
                    "</globalConfiguration>\n" +
                        " <transport name=\"http\" " +
       
"pivot=\"java:org.apache.axis.transport.http.HTTPSender\"/>\n" +
                    "</deployment>";
            
             
            static XMLStringProvider clientProvider = new
XMLStringProvider(clientWSDD);
           
            public static void main(String[] args) {
               
                try {
                    String FMConnector_address =
"http://localhost:8080/axis/services/FMConnector";;   
                    Service svc = new Service(clientProvider);
                    svc.setMaintainSession(true);

                    Call call = (Call)svc.createCall();
                    call.setTargetEndpointAddress(new
java.net.URL(FMConnector_address));
                   
                    System.out.println(call.invoke("FMConnector",
"commitReceipt", null));
                    System.out.println(call.invoke("FMConnector",
"commitReceipt", null));

                    System.out.println(call.invoke("FMConnector",
"commitReceipt", null));
                    System.out.println(call.invoke("FMConnector",
"commitReceipt", null));
                } catch (Exception e) {
                    e.printStackTrace();
                }
               
            }
        }

I'm just calling the service method four times. That works but there is no
session ID in the request (!?)

        <?xml version="1.0" encoding="UTF-8"?>
        <SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/";>
         <SOAP-ENV:Body>
          <ns1:commitReceipt xmlns:ns1="FMConnector"/>
         </SOAP-ENV:Body>
        </SOAP-ENV:Envelope>

So what's wrong ?

A few words to the wsdd in the client app. I used that bit in the originally
example and it works fine.
I tried also variations with <requestFlow> and <responseFlow> inside the
<transport> tag.


Another question:
How can I set e.g. the timeout for the SessionHandler ? Is there a way to
put it in server wsdd ?
As I mentioned before, the server bits are generated. In which part can I
put handler related stuff like changing the timeout programmatically (in the
skeleton ?).

Thanks


Sven
