我想在Tomcat中使用以下server.conf運行兩個BaseX實例。我遇到了一個奇怪的問題：它們都在各自的端口上可用，但是webapp本身是相同的WAR;即webapps/WAR中只有的鏈接出現在從webapps2加載的WAR中。我不確定我的下一步應該是什麼 - 我會問BaseX郵件列表，但他們沒有在那裏使用很多的Tomcat。Tomcat多服務 - 啓動問題
這裏是我的server.conf中
<Service name="Catalina">
<Connector port="8080"
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.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
</Realm>
<Host name="localhost"
appBase="webapps"
unpackWARs="true"
autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs"
prefix="localhost_access_log."
suffix=".txt"
pattern="%h %l %u %t "%r" %s %b"/>
</Host>
</Engine>
</Service>
<Service name="Catalina2">
<Connector port="18080"
protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="18443"/>
<Connector port="18009" protocol="AJP/1.3" redirectPort="18443"/>
<Engine name="Catalina2" defaultHost="localhost">
<Host name="localhost"
appBase="webapps2"
unpackWARS="true"
autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs2"
prefix="localhost_Cat2_access_log."
suffix=".txt"
pattern="%h %l %u %t &quot;%r&quot; %s %b"/>
</Host>
</Engine>
</Service>
當我啓動Tomcat，一切都在這兩個服務的負荷還好，除了第二BaseX應用。當Tomcat開始加載時，我收到以下錯誤：

我不太確定端口是否會導致問題。 netstat和其他使用中的端口不會返回任何有用的內容。
