最近学习soa，照着网上的例子弄bpel，遇到个问题，没有解决的思路。
报这个异常：
Multiple annotations found at this line:
- !!BPELC_PA__MSG_TYPE! [0=bpel:invoke,1=addOrder,2={http://schemas.xmlsoap.org/wsdl/}output,3=addOrderResponse,4={4},5={5}]
- !!BPELC_PA__OMIT! [0=java.lang.IllegalArgumentException: Choice Pattern incorrect: 0#node <{4}> |2#attribute "{4}",1=java.lang.IllegalArgumentException,2={2},3={3},4={4},
5={5}]
- !!BPELC_PA__MSG_TYPE! [0=bpel:invoke,1=addOrder,2={http://schemas.xmlsoap.org/wsdl/}input,3=addOrder,4={4},5={5}]
bpel文件中，红色字体的地方报错：
