通过MyEclipse 6.5 开发基于JAX的东东。

//这是生成client时的警告，不过好像指没有验证，对之后的使用没有发现问题。
WS-I: A problem occurred while running the WS-I WSDL conformance check:
org.eclipse.wst.wsi.internal.analyzer.
WSIAnalyzerException.
The WS-I Test Assertion Document(TAD) was either not found or could not be processed.
The WSDLAnalyzer was unable to validate the given WSDL file.

如果使用web项目（包括web service）时生成客户端使回到问题。
这是在web项目下做client测试时发生的exception，在java application中没有问题
Exception in thread "main" java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/C:/Program%20Files/MyEclipse%206.5/myeclipse/eclipse/plugins/com.genuitec.eclipse.ws.xfire_6.5.1.zmyeclipse650200806/lib/webservices-rt.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.5.0/docs/guide/standards/)

解决方法：是jar包jaxb的版本冲突了。删掉MyEclipse中为你添加的javaEE的包。
希望大家原谅本人水平有限，希望能跟大家一起进步~~
