I'm running a JAX-WS web service which is based on Apache CXF 2.3.1 on a JBoss6 server.

My service offers a function `getWeight`. This function should return the values in different units (kilos, pounds) depending on an additional information within the SOAP header. For that purpose I have added my own interceptor:

```
public class MySoapHeaderInterceptor extends AbstractSoapInterceptor
{
    public MySoapHeaderInterceptor()
    {
        super(Phase.USER_PROTOCOL);
    }

    ...
}

```

The intercepting works fine and I can parse the additional element from the SOAP header and can set up a variable based on this element:

```
boolean poundsRequested = true;

```

Now my problem occurs. I don't know how to forward the variable `poundsRequested` to my actual WebService implementation `MyServiceImpl`. This class is calling another class `ValueReader` where I finally need the information from the SOAP header. 

I've already tried to set up a global static variable `ValueReader.poundsRequested`. But such a solution is not thread safe. It might happen that the calls of two clients interfere, and can overwrite each others set up variable.

**To sum up**: I basically need a possibility to forward a variable from an Apache CXF Interceptor to the actual webservice implementation. Moreover the value of this variable needs to be unique for each request.
