Using Xfire to transfer a file

[ying lam]

Hi,

I am trying to use xfire to transfer a file.

I have a WebService client which calls a method call 'getLog' to get a file from the WebService server.

My service.xml

  <properties>
   <property key="mtom-enabled">true </property>
   </properties>

On my Web Service server, i have printfs statement on my server on
before and after return the datasource, it works (I see the printfs at
the console).
My Server code:
[code]
public DataSource getLog()
{
System.out.println (" getLog is getting called");

try {
DataSource ds = new FileDataSource ("/hibernate_db.properties" ) ;

System.out.println ("done created!");

return ds;

} catch (Throwable t) {
t.printStackTrace();
}
return null;
}
[\code]


My client code:
[code]
DataSource source = service.getLog();

I set breakpoint at the client, it fails when it is calling that method.

[code]

I get this exception:
[code]

Exception in thread "main" org.codehaus.xfire.XFireRuntimeException:
