我尝试重新安装JBoss，但在部署时仍然遇到相同的异常。 我已经尝试过更改
了<virtual-server name="default-host" enable-welcome-root="true">
to <virtual-server name="default-host" enable-welcome-root="false">
但是，通过此更改，我的应用程序无法以正确的方式运行。
我需要使用<virtual-server name="default-host" enable-welcome-root="true">

以下可能是
的原因要解决此问题，请在Jboss-web.xml中为不同的战争提供不同的上下文根
