我们可以使用jaxws-rt.jar作为运行时实现，虽然它包含sun库吗？

Question

Many recommend not to use sun packages for various reasons. Detailed answers are provided here .

However I am using jaxws-rt.jar which uses sun library.

I am wondering if I should jaxws-rt.jar or not. I am running in tomcat container and I do not want to include jaxws implementations of Jboss,GlassFish or any other application servers.

Here is what I am trying to do (setting connection and request timeouts)

import com.sun.xml.internal.ws.client.BindingProviderProperties;
import javax.xml.ws.BindingProvider;

((BindingProvider)soapService).getRequestContext()
        .put(BindingProviderProperties.REQUEST_TIMEOUT,REQUEST_TIMEOUT_MILLI);
((BindingProvider)soapService).getRequestContext()
        .put(BindingProviderProperties.CONNECT_TIMEOUT,CONNECT_TIMEOUT_MILLI);

Thanks

As you've found, certain behaviors (such as connection timeouts) are controlled through implementation-specific means.

If you're not keen on compiling against (importing) the com.sun packages, one way to remove the compile-time dependencies yet set these properties to control the JAX-WS reference implementation the way you need, you can try just setting the BindingProvider request context properties for the reference implementation by their string values . You can set these properties even when running with other JAX-WS runtimes than the RI - it won't fail (it just may have no effect).

import javax.xml.ws.BindingProvider;

((BindingProvider)soapService).getRequestContext()
    .put("com.sun.xml.ws.request.timeout", 5000L);
((BindingProvider)soapService).getRequestContext()
    .put("com.sun.xml.ws.connect.timeout", 5000L);

Here are the two values for both constants in your question. JAXWSProperties.CONNECT_TIMEOUT and BindingProviderProperties.REQUEST_TIMEOUT .

This is a misunderstanding.

even though it includes sun libraries?

It doesn't 'include sun libraries'. It refers to a com.sun library. That's a completely different thing. Two completely different things.

Many recommend not to [use] sun packages for various reasons.

There is only one recommendation that counts, and it is the Note about sun.* packages . The operative sentence in that is:

Programs that contain direct calls to the sun.* packages are not 100% Pure Java.

The sun.* packages are there for a reason of course, and that is to provide implementations for various things in the JDK . If that's the only use your program makes of these classes, and specifically if your code doesn't contain 'direct calls to the sun.* packages', you don't have anything to worry about.
