axis 1.4 not maintaining session
Greetings,
I'm trying to get Axis 1.4 to maintain a session for me.
Here is my Java class:
public class StatefulService {
private String keyValue; //this is the 'state' being
maintained
public String setKey() {
keyValue = "theValue";
return "value was set in private member variable";
}
public String getKey() {
String msg = "";
if(keyValue==null)msg = "Session state is not being maintained";
else msg += "keyValue= " + keyValue;
return msg;
}
}
Here is my client, a jsp being called via Ajax:
<%@ page language="java"
import="org.apache.axis.client.Call,
org.apache.axis.client.Service,
org.apache.axis.encoding.XMLType,
javax.xml.rpc.ParameterMode,
javax.xml.namespace.QName,
java.net.URL" %>
<%
String ret = "yada";
String endpointURL =
"http://localhost:8080/axis/services/StatefulService";
try {
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new java.net.URL(endpointURL) );
call.setReturnType( XMLType.XSD_STRING );
call.setMaintainSession(true);
call.setOperationName( "getKey" );
ret = ret + (String) call.invoke( new Object[] { } );
ret = ret + "\n";
call.setOperationName( "setKey" );
ret = ret + (String) call.invoke( new Object[] { } );
ret = ret + "\n";
call.setOperationName( "getKey" );
ret = ret + (String) call.invoke( new Object[] { } );
} catch (Exception e) {
ret = e.toString();
}
out.println(ret);
%>
Here is my WSDD file I am using to deploy the web service:
<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="StatefulService" provider="java:RPC">
<parameter name="className" value="StatefulService"/>
<parameter name="allowedMethods" value="*"/>
<parameter name="scope" value="session"/>
</service>
</deployment>
When I call this the first time I get:
Session State is not being maintained
value was set in private member variable
keyValue=theValue
When I call it the second time I get the same thing, but I expect:
keyValue=theValue
value was set in private member variable
keyValue=theValue
What in the world am I doing wrong? I've been baning my head against a
wall over this for 2 days reading and trying every example online that I
can find.
Much Thanks in Advance,
Jim

Andrew,
I tried what you suggested but I am still getting the same behavior as
before.
Also, if I set scope to "application" it DOES maintain the class
variable, but when I try "session" it acts like requested.
Any other suggestions?
Thanks,
Jim

Try this:
public String setKey()
{
getSession().set("keyValue", "theValue");
return "value was set in private member variable";
}
public String getKey()
{
String msg = "";
String keyValue = (String) getSession().get("keyValue");
if(keyValue==null)msg = "Session state is not being maintained";
else msg += "keyValue= " + keyValue;
return msg;
}
private Session getSession()
{
MessageContext mc = MessageContext.getCurrentContext();
mc.setMaintainSession(true); // Setup the session
return mc.getSession();
}
