Error publishing extension in server (Java Stack)


I'm doing a client to consume a web service and when I try to publish I get this error:

    package does not exist [javac] import;

I generated my classes from wsdl using JAX-WS RI 2.1.7-b01- / Generated source version: 2.1.

The platform server is 5.0 for Java. 

The output from $java -version is

java version "1.6.0_27"
Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)

Can anyone help?

Hi João,
I found the class BindingProviderProperties , in two jars, in rt.jar from the jdk (not sure if it exists in the jre) and in jaxws-rt.jar (from jaxws libraries).
Maybe you're using the wrong one
I would like you to provide more information if possible, perhaps give me a minified sample extension where the problem occurs.
For future reference and because the extension dealt with private information here's what Luís suggested:

I had a line like this in my code that was originating the error publishing

    bp.getRequestContext().put(JAXWSProperties.REQUEST_TIMEOUT, inParamrequestTimeout);

and was replaced by this one
    bp.getRequestContext().put("", inParamrequestTimeout);

Thank you Luís.
