Tomcat_配置多个端口

<Service name="Catalina">
        <Connector port="8090"
                   maxHttpHeaderSize="8192"
                   maxThreads="150"
                   minSpareThreads="25"
                   maxSpareThreads="75"
                   enableLookups="false"
                   redirectPort="8443"
                   acceptCount="100"
                   connectionTimeout="20000"
                   disableUploadTimeout="true" />
        <Connector port="8009"   enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
        <Engine name="Catalina" defaultHost="localhost">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
        <Host name="localhost"
                    appBase="webapps"
                    unpackWARs="true"
                    autoDeploy="true"
                    xmlValidation="false"
                    xmlNamespaceAware="false">
        </Host> </Engine>
    </Service>

 （2）比着上面的葫芦画下面的瓢、新增两个端口号，注意Service name、Engine name、appBase，  当然了，端口号别忘了修改，以免重复。

<Service name="Catalina1">
        <Connector port="8091"
                   maxHttpHeaderSize="8192"
                   maxThreads="150"
                   minSpareThreads="25"
                   maxSpareThreads="75"
                   enableLookups="false"
                   redirectPort="8443"
                   acceptCount="100"
                   connectionTimeout="20000"
                   disableUploadTimeout="true" />
        <Connector port="8009"
                   enableLookups="false"
                   redirectPort="8443"
                   protocol="AJP/1.3" />
        <Engine name="Catalina1" defaultHost="localhost">
            <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
            <Host name="localhost" appBase="webapps1" unpackWARs="true" autoDeploy="true"  xmlValidation="false" xmlNamespaceAware="false"></Host>
        </Engine>
    </Service>
    <Service name="Catalina2">
        <Connector port="8092"
                   maxHttpHeaderSize="8192"
                   maxThreads="150"
                   minSpareThreads="25"
                   maxSpareThreads="75"
                   enableLookups="false"
                   redirectPort="8443"
                   acceptCount="100"
                   connectionTimeout="20000"
                   disableUploadTimeout="true" />
        <Connector port="8009"   enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
        <Engine name="Catalina2" defaultHost="localhost">
            <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
            <Host name="localhost" appBase="webapps2" unpackWARs="true" autoDeploy="true"  xmlValidation="false" xmlNamespaceAware="false"></Host>
        </Engine>
    </Service>

 第二步、创建相应的部署目录 ..\Tomcat 6.0\webapps1 
                     ..\Tomcat 6.0\webapps2  
  同时可以将Tomcat 6.0\webapps下的有用的复制到新建的部署目录 
第三步、创建配置文件目录和配置文件 
..\Tomcat 6.0\conf\Catalina1\localhost
..\Tomcat 6.0\conf\Catalina2\localhost 
host-manager.xml manager.xml  配置文件的配置可参照..\Tomcat 6.0\conf\Catalina\localhost下的，只需要修改一下对应目录即可  
大概的配置步骤就是这些，现在可以把不同的war包放在不同的位置来访问了 以上配置方法同样适合Tomcat 5.5  。
Tomcat6 配置多虚拟主机，多域名绑定一IP 
实现效果： 
http://localhost 访问一个项目例如一个系统1。 
http://localhost1 访问一个项目例如一个系统2 
实现方案，需要修改两个地方  
一个是C:\WINDOWS\system32\drivers\etc\hosts文件，改为 127.0.0.1      localhost 
               127.0.0.1      localhost1

另一个要改的就是server.xml，修改后如下：

<?xml version='1.0' encoding='utf-8'?>
    <Server port="8005" shutdown="SHUTDOWN">
        <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
        <Listener className="org.apache.catalina.core.JasperListener" />
        <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />
        <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
        <GlobalNamingResources>
            <Resource name="UserDatabase" auth="Container"
                      type="org.apache.catalina.UserDatabase"
                      description="User database that can be updated and saved"
                      factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
                      pathname="conf/tomcat-users.xml" />
        </GlobalNamingResources>
        <Service name="Catalina">
            <Connector port="80" protocol="HTTP/1.1"
                       connectionTimeout="20000" redirectPort="8443" />
            <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
            <Engine name="Catalina" defaultHost="localhost">
                <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
                <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" debug="0">
                    <Context path="" docBase="E:\Tomcat6\webapps\YangFan\" reloadable="true" crossContext="true"/>
                </Host>
                <Host name="localhost1" appBase="webapps" unpackWARs="true" autoDeploy="true" debug="0">
                    <Context path="" docBase="E:\Tomcat6\webapps\hiccOffice\" reloadable="true" crossContext="true"/>
                </Host>
            </Engine>
        </Service>
    </Server>

 问题：1.  报 Caused by: Caught exception while loading file struts-default.xml 错     
解决：  删除lib下的xerces-2.6.2.jar
