我有两个webservice SOAP(Axis2)和另一个类型REST(Jersey 2).
一切正常,但我想把一个放在端口8080上,一个放在端口8081上.
我开始在tomcat/conf文件夹中编辑我的server.xml,用他自己的连接器,引擎和主机创建一个新服务,如下所示:
server.xml:
我在第二个服务上的上下文有问题.当我添加这个并尝试启动Tomcat时,我遇到了这个异常:

当我删除上下文tomcat启动并在此端口上侦听.
这是我第一次尝试这样做,我做错了什么,但我不知道我在google和stack上搜索的位置,但我还没有找到解决方案.
我在windows 10,tomcat 8和eclipse Mars上工作.
如果你们其中一个人知道解决方案,我将非常感谢他的帮助.谢谢
您的问题是，您正在尝试从Eclipse IDE中以这种配置启动Tomcat。
Ghayel是正确的，以下是主要原因：
Caused by: java.lang.IllegalArgumentException: The main resource set specified [C:\DEV\eclipse\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps\REST] is not valid at org.apache.catalina.webresources.StandardRoot.createMainResourceSet(StandardRoot.java:723) at org.apache.catalina.webresources.StandardRoot.startInternal(StandardRoot.java:684) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150)
有关参考，请参阅Tomcat FAQ中的Eclipse IDE和Eclipse处的Eclipse WebTools Project Tomcat FAQ。
您的问题是由以下两个事实的组合引起的：
默认情况下，Eclipse IDE不使用server.xml您在IDE中编辑的文件，但是在复制到其他“ CATALINA_BASE”目录中时会对其进行处理。从您的日志消息中，该目录为C:\DEV\eclipse\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps。
首先，查看conf/server.xml该目录中的文件。它可能与您编辑的文件不同。
其次，我希望的Eclipse IDE处理server.xml不支持多个Engine元素。（它可能会支持他们，但如果这样做，我会感到惊讶）。
如果Context在server.xml中定义了element，则无法启动此上下文会导致整个Tomcat的启动失败。
这是未在中定义Context元素的原因之一server.xml。
AFAIK（Eclipse中的Tomcat服务器）可以配置为使用不同的CATALINA_BASE目录，并且可以配置为将上下文发布为xml文件（而不是将其放入server.xml），但是我仍然怀疑这样的配置是否支持多个Engine元素。
我认为您最好的选择是在Eclipse外部配置Tomcat实例，并使用其他工具（例如Apache Ant）在其中打包和部署您的Web应用程序（通过复制文件+依靠自动部署，或通过使用Tomcat Ant任务来完成）将应用程序部署到正在运行的Tomcat实例上）。
如果您不需要这些Web服务位于同一JVM上，只需在Eclipse中配置几个Server实例并并行启动它们即可。（当然，它们的端口号必须不同）。
