我使用gwtupload插件在GWT中开发了多个文件上传。它在调试模式下工作正常。我创建了war并在jboss-as-7.1.1.Final开始。如果我上传一个文件它的工作正常，但当我选择其他文件上传其投掷和错误。
java.lang.RuntimeException: The request has been rejected because the server is already receiving another file.这是我的服务器日志。现在该如何解决这个错误？

发生这种情况是因为servlet中使用的前一个侦听器尚未从内存中删除。通常，如果浏览器中有多个选项卡实例，或者在上载文件时重新加载应用程序，则可能会发生这种情况。等一会儿，再试一次。
我从未在我的项目中使用jboss，因此可能是其servlet容器中的一个问题，尽管它使用了与gwtupload兼容的tomcat。
如果您可以在一个可以重现问题的简单项目中隔离问题，请将其发布，以便我可以查看和调试。
