我做了一个网络服务。我已经提供了2或3项服务，并将这些服务部署在玻璃鱼上。在每个服务上我使用的包名称如pk.mazars.basitMahmood.calculate，pk.mazars.basitMahmood.weather等。意味着pk.mazars.basitMahmood在所有包名中都很常见。现在我在eclipse上开发了一个Web服务，现在当我尝试部署它时，我收到以下错误
cannot Deploy ResourceAEAR
org.eclipse.core.runtime.CoreException: Deployment Error for module: ResourceAEAR:
Error occurred during deployment: Exception while loading the app :
java.lang.Exception: WEB0113: Virtual server [server] already has a web module

therefore web module [ResourceAEAR#AndroidBackendAuthentication.war] cannot be
loaded at this context path on this virtual server. . Please see server.log for
more details.

这个错误意味着什么。我该如何解决？我也对这个错误做了一些谷歌，但无法确切找到问题所在。所以请帮忙:(
