cxf做客户端时，报 javax.xml.bind.JAXBException: "" doesnt contain ObjectFactory.class
整个异常信息中，还有个错误提示：
[error] IOException during exec() of compiler "javac". Check your path environment variable.
在网上查了查，是这个原因：
“CXF tools need javac to compile the generated source files.
Please add the javac's directory into the PATH environment variable.”
原来，我在环境变量里只设置了 java_home，没在path里面加上 %java_home%\bin....
