异常产生场景： 用jax-ws编写服务器端代码，当使用byte[]参数时，wsgen可以产生配置文件，但是用wsimport导出客户端代码时，报以上异常。

异常原因： 可能是jdk1.6 和 JAXWS2.2.7 版本之间的冲突。

用jdk_home下的wsimport命令使用成功，用JAXWS2.2.7/bin中的wsimport命令出错。

解决方法：

<target name="generate-client-2" depends="wsgen">

   <exec executable="${env.JAVA_HOME}/bin/wsimport">

       <arg line="-d D:\workspace_PMS\JaxWSProject\build2 -g -keep -s D:\workspace_PMS\JaxWSProject\build2 -verbose http://localhost:8089/JaxWSProject/HelloService?wsdl -p com.ws"/>

   </exec>

</target>
