环境：
- Ubuntu 14.04
- Netbeans 8.0.2
- 野蝇8.2.1
- JDK 1.8.0_60
我可以在没有错误的情况下进行构建，但当我尝试运行项目时，我会遇到这个错误，但我还没有任何持久性配置。

我该怎么解决这个问题？
您的服务器无法启动，因为您的服务器配置有问题。根据您的错误消息，您的配置从以下内容开始：
<?xml version='1.0' encoding='UTF-8'?>
<server xmlns="urn:jboss:domain:3.0">
...
但据我所知，wildfly8.2.1支持2.2版的服务器配置，您的配置应该是这样的：
<?xml version='1.0' encoding='UTF-8'?>
<server xmlns="urn:jboss:domain:2.2">
...
这怎么会发生？最有可能的是，您错误地配置了IDE或环境属性，所以Wildfly在错误的位置进行配置。检查JBOSS_HOME环境属性，在大多数情况下您不需要它，所以取消设置。
$ env | grep JBOSS_HOME
否则，请仔细查看Netbeans中的服务器配置。
