com.sun.xml.internal.ws.developer.JAXWSProperties not found at compile
提问by Alexander Rühl
We used the class JAXWSPropertiesfrom the com.sun.*package in the code in order to set timeout properties like this:
我们使用了类JAXWSProperties从com.sun.*包中的代码，以这样的设置超时属性：
import com.sun.xml.internal.ws.developer.JAXWSProperties;
...
Map<String, Object> ctxt = ((BindingProvider) port).getRequestContext();
ctxt.put(JAXWSProperties.CONNECT_TIMEOUT, 10000);
It compiles fine in the local Eclipse, but not on a continuous integration system (both using JDK 1.6). From researching this problem, I learned that the com.sun.*package should be avoided.
它在本地 Eclipse 中编译良好，但在持续集成系统（均使用 JDK 1.6）上编译不正常。通过研究这个问题，我了解到com.sun.*应该避免使用包。
So my questions are:
所以我的问题是：
- What causes the failed import at compile time?
- What should be used instead of
JAXWSProperties?
- 编译时导入失败的原因是什么？
- 应该用什么代替
JAXWSProperties？

I've just had pretty much the same problem while converting one of our projects to run under Maven.
在将我们的一个项目转换为在 Maven 下运行时，我遇到了几乎相同的问题。
The solution I found, isn't really an ideal solution, in fact it's more of a "cludge" than a "fix," although it does run through the compiler OK. Like you I did a bit of research on this issue, and found a comment from Sun saying that these packages are hidden from the compiler, but are available to the JVM.
我发现的解决方案并不是真正的理想解决方案，实际上它更像是“杂物”而不是“修复”，尽管它确实可以通过编译器运行。像你一样，我对这个问题做了一些研究，发现 Sun 的评论说这些包对编译器是隐藏的，但对 JVM 可用。
So, the solution I found was to simply find the string to which the constant was pointing, and use that locally.
所以，我找到的解决方案是简单地找到常量指向的字符串，并在本地使用它。
In your case it would be:
在您的情况下，它将是：
final static String CONNECT_TIMEOUT = "com.sun.xml.internal.ws.connect.timeout";
....
Map<String, Object> ctxt = ((BindingProvider) port).getRequestContext();
ctxt.put(CONNECT_TIMEOUT, 10000);
As I mentioned, this isn't ideal, and can not be guaranteed to work in future compiler releases, so use with care.
正如我所提到的，这并不理想，并且不能保证在未来的编译器版本中工作，因此请谨慎使用。
