文件上传机制被添加到我现有的应用程序中，该应用程序已部署到WebSphere 7.我使用commons-fileupload-1.2.2.jar进行文件上载。在测试期间，我遇到了以下异常：

有人可以分享一些有关导致上述异常的见解。虽然异常可能指向服务器长响应或由于处理服务器中的超时，但有没有办法解决这个问题？就像在代码端处理异常一样？非常感谢您的帮助。如果我需要包含其他信息来解决此例外情况，请与我们联系。谢谢！
答案 0 :(得分：1)
似乎需要增加文件上传超时时间。我遇到过同样的情况，但我需要的是通过管理控制台将我的应用程序上传到websphere。由于我的应用程序很大，我必须增加管理控制台的时间。
由于您的方案是在websphere中托管的应用程序中上传文件，因此您必须更改不同队列的时间。
