ajax 报错
大家好，我做了个ajax本地机上一切正常，部署到服务器上就不能用了，下面是爆出的错误：
com.easyjf.web.ajax.ServiceNotAvailableException: frameworkException: 名为null的Ajax服务不可用，可能是名字已经被限制!
后台的报错是：
com.easyjf.web.ajax.ServiceNotAvailableException: frameworkException: 名为null的Ajax服务不可用，可能是名字已经被限制!

配置文件：
<ajax>
<services allowName="*">
<service name="modifyinfoService">
<include method="canModifyByCompany" />
</service>
</services>
</ajax>
请问问题是出在哪儿呢？ easyjweb 的框架。
页面上的引用：、
<script src="ejf/easyajax/prototype.js" type="text/javascript"></script>
<script src="ejf/easyajax/engine.js" type="text/javascript"></script>
<script src="ejf/easyajax/modifyinfoService.js" type="text/javascript"></script>
modifyinfoService.cantime(function(result){
.............
})
[解决办法]
你的后台用来接收 ajax 请求的代码是？
[解决办法]
有值为 nulll .了
