Axis调用webservice中遇到的问题，请指教。

下面是产生的错误，不清楚怎么回事，有谁能帮忙解答一下，如需要提供其他内容，请回复，谢谢！

[b]问题补充：[/b]
谢谢xuxiaolei的回复，我看到faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Client 这个，这个是不是说是客户端产生的问题，可是我客户端并没有用hibernate，怎么会有could not get next sequence value; nested exception is org.hibernate.exception.SQLGrammarException: 的异常呢？
异常是在程序代码中java.lang.Object _resp = _call.invoke(new java.lang.Object[] {in0});这行发生的。这些有说明什么呢？谢谢！

nested exception is org.hibernate.exception.SQLGrammarException: could not get next sequence value
应该是client端或service端中hibernate取得sequence出现的异常。检查下你的hibernate中取得sequence部分的配置代码吧。

java.lang.Object _resp = _call.invoke(new java.lang.Object[] {in0});
这句就是client调用service端服务的代码。

有可能service端用的hibernate吧，可能是service端的问题
