问一下java调用bpel的问题（SOA高手进来啊）

Question

我最近在学习oracle的bpel，使用jdeveloper直接创建一个同步的流程，即synchronous bpel process，然后调用，就会一直报axis的错误。
对应发布服务的wsdl为

System.out.println(result); }}
请高手帮我弄弄啊。我觉得我快崩溃了。哎。

Answer 2

先检查下你的jdk版本，如active bpel用的是jdk5，如果是你的环境中的
jdk7就会出现这样的情况，试试吧
如果用过active bpel请跟我联系

我想知道怎么用axis2，好烦啊，jax-ws好上手多了
