每当我在带有无接口EJB的动态web maven项目上的eclipse helios中执行Run on Server时，Glassfish会间歇性地部署它。成功部署通常使用以下内容进行记录：

但是，它偶尔会部分部署只有这个
INFO: file:/C:/glassfish3/glassfish/domains/domain1/eclipseApps/suffuse-management-console/WEB-INF/classes/_suffuse-management-console20748433 logout successful
INFO: WEB0671: Loading application [suffuse-management-console] at [/suffuse-management-console]

访问我的servlet时出现404错误。要完全部署它，我必须执行Project - ＆gt;清理然后再次执行Run on Server而不删除资源，它就可以了。有谁知道这背后的原因和永久性的补救措施？
