关于AXIS Server.generalException错误

客户端调用WebService时出现异常，代码：        org.apache.axis.client.Call _call = createCall();
        _call.setOperation(operations[1]);
        _call.setUseSOAPAction(true);
        _call.setSOAPActionURI("");
        _call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS);
        _call.setOperationName(new javax.xml.namespace.QName("http://josso.org/gateway/identity/service/ws/impl", "findUserInSession"));        setRequestHeaders(_call);
        setAttachments(_call);
try {
   java.lang.Object _resp = _call.invoke(new java.lang.Object[] {username});
}catch(org.apache.axis.AxisFault axisFaultException){
   throws axisFaultException;
}
产生的异常信息： AxisFault

_call.invoke(new java.lang.Object[] {username})调用以上代码时出错！
是不是漏了什么关键代码比如call.setTargetEndpointAddress等
首先要保证ws调用框架代码的普遍正确性然后再研究参数的问题我觉得
我也遇到了类似的问题，看了好几个帖子，好像说是在tomcat中的引用出错了

同问，刚刚遇到这个问题。
我觉得是对方返回的soapMessage与本地的Bean不符，但对方是不可能改的，自己改，问题是怎么改呢？
请问LZ客户端调用WEB SERVICE的代码是不是用ECLIPSE 自动生成的客户端代码？
