Newbie Instantiation question

[Torsten Rüger <to...@firsthop.com>]

Moi,

so I just got my "hello world" (userguide/example3) to work and all 
looks fine.

But for real life, I want to access existing objects. So axis wouldn't 
intantiate the object, especially not for every call to the service.

Is there a way to describe this using the wsdd. For example to specify a 
factory method for the class ?
As in:

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
            xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

 <service name="MyService" provider="java:RPC">
  <parameter name="className" value="samples.userguide.example3.MyService"/>
#### guess work ####
  <parameter name="factoryMethod" value="my.package.class.staticMethod" >
    <arg  name="uri" />  ## or <arg name="serviceName"/>
### ??
  <parameter name="allowedMethods" value="*"/>
 </service>

</deployment>

Any other ideas how to do this are welcome ,

    Thanks
        Torsten

Ok, that sounds sort of promising. Do I take it that then the service 
would be only instantiated once ? Still, by who, or how ?
And where do I find this documented ?

 From the User guide:

"The skeleton contains an implementation of the AddressBook service.  
This implementation is either passed into the skeleton on construction, 
or an instance of the generated implementation is created.  When the 
AXIS engine calls the skeleton's addEntry method, it simply delegates 
the invocation to the real implementation's addEntry method."

So I understand I could use the *WSDL*2Java tool, generate those 
skeletons and pass my implementation in. But how ? Same question again, 
who instantiates the Skeleton ?

Thanks

Hi,
I thinks you speak about scope in web service. You can specify scope for
your service with an extra parameter in wsdd file:

...
<Parameter name="scope" value="Application"/>
...

By default, this parameter is set to Session
