我刚刚在websphere中部署EARS时遇到了问题。我在安装应用程序后遇到的错误如下所示。

我认为这与web.xml中的资源绑定有关，但我不确定。我没有创建ibm专有绑定文件并将其包含在EAR中，而是期望在部署过程中完成。为了实现这一点，我试图告诉它在覆盖现有绑定时生成新绑定，以及绑定设置的其他组合，但我似乎总是得到上面的错误。我在下面提供了我的web.xml。你能找出出错的东西吗？我已经尝试删除resource-ref元素的id属性，但这似乎没有帮助。

非常感谢你的帮助。 杰里米

问题是由两个具有相同名称的不同servlet引起的。一旦我拿出下面提供的项目，我就能够再次成功启动应用程序。
<servlet-mapping>
<servlet-name>
default
</servlet-name>
<url-pattern>
/css/*.css
</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>
default
</servlet-name>
<url-pattern>
/js/*.js
</url-pattern>
</servlet-mapping>
我希望这有助于其他人。

检查您是否要安装与WAS中已安装的相同的耳朵（名称不同）。
我在上述问题上也遇到了类似的例外情况
