高分求解

使用JAX-WS 2.1生成webservice客户端后，编译为5.0版本的class，测试环境JDK6.0，Tomcat5.0运行正常，正式环境同样是JDK6.0，Tomcat5.0，但是在正式环境中抛出空指针异常，无法正常工作，求解。
错误日志如下：java.lang.NullPointerException

解决方案 »

  1.   

    经过自己排查，发现是由于jdk的版本不统一，导致通过jax-ws生成的类产生了问题。在服务器端使用wsimport生成类文件后，使用javac -target 1.5将类重新编译为1.5版本的class，调用成功。
      

  2.   

    JDK版本不一样
    这种错误都能有。。
    恩记住了
      

  3.   

    确实没想到会存在这样的问题，而且很明显能感觉到beta2版的jdk和正式版的jdk在使用wsimport生成webservice客户端的时候存在明显差异，真是学了个乖
