Java使用JAX-WS来写webservice时 Unable to create JAXBContext

<

div id=”content” contentScore=”3754″>webservice，作为web开发人员来说必须掌握的一门技术，它的好处这里就不多说了，MyEclipse中自带了一种生成webservice的方法，使用JAX-WS，如果我没有弄错的话，它需要javaEE5.0、JDK1.5以上，了解完这些就开始写接口方法。各种随心所欲。不料在用MyEclipse生成webservice时出现错误了，生成不了，错误信息如下“ An internal error occurred during: “Generating JAX-WS Web Services”. Unable to create JAXBContext ”  ,错误堆栈如下：

真心让人郁闷，尤其是刚开始搞webservice的时候。其实仔细阅读一下堆栈信息就会发现，说 ResultSet是一个接口，而JAXB不能处理接口。记得网上有人说 JAX-WS只支持基本数据类型，int、String等，其实不是的，JAX支持的数据籼/div>
