我首先启动了我的 WebSphere Application Server 8.5.5.0，没有部署任何应用程序，它启动良好，文本如下。
Launching defaultServer (WebSphere Application Server 8.5.5.0/wlp-1.0.3.20130510-0831) on Java HotSpot(TM) 64-Bit Server VM, version 1.7.0_51-b13 (en_US)
[AUDIT ] CWWKE0001I: The server defaultServer has been launched.
[INFO ] CWWKE0002I: The kernel started after 1.714 seconds
[INFO ] CWWKF0007I: Feature update started.
[AUDIT ] CWWKZ0058I: Monitoring dropins for applications.

[INFO ] CWWKO0219I: TCP Channel defaultHttpEndpoint has been started and is now listening for requests on host 127.0.0.1 (IPv4: 127.0.0.1) port 9080.
当 WebSphere 启动时，我使用 Eclipse 将我的 war 文件导出到 Eclipse，它部署到插件目录中。这部分也成功了，我在服务器日志中得到了额外的输出：
[INFO ] CWWKZ0018I: Starting application iaat.
[WARNING ] CWWJP9991W: openjpa.Runtime: Warn: An error occurred while registering a ClassTransformer with JPAPUnitInfo(PuId=iaat#iaat.war#DB2-Config)@3476b7f1. The error has been consumed. To see it, set your openjpa.Runtime log level to TRACE. Load-time class transformation will not be available.
[INFO ] CWWJP9990I: openjpa.Runtime: Info: OpenJPA dynamically loaded a validation provider.
[INFO ] SRVE0169I: Loading Web Module: iaat.

[AUDIT ] CWWKT0016I: Web application available (default_host):
[AUDIT ] CWWKZ0001I: Application iaat started in 6.774 seconds.
我的问题是当我尝试使用 WebSphere 提供的 URL 启动我的应用程序时。当页面在 Internet Explorer 中出现时，我在 WebSphere 日志中收到以下消息。我确实查看了生成的 War 文件，它抱怨的类文件位于 WEB-INF/classes/com/bah/iaat/model/data/Proposal
