在Tomcat下分別單獨部署兩個專案時，是正常的，都可以訪問到專案的主頁，可是在同時部署這兩個專案時，就只能訪問一個專案的主頁，另一個專案訪問主頁時報404錯誤，這是為什么呢？
另外在啟動Tomcat時也沒有報錯，訪問的時候報錯如下：
這是為什么呀？
uj5u.com熱心網友回復：
看一下localhost.log里面的內容uj5u.com熱心網友回復：
可是在同時部署這兩個專案時re:
不太懂？只要conf/server.xml中設定不同Host是沒問題的
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
</Host>
<Host name="www.域名.net" appBase="專案所在的路徑" unpackWARs="true" autoDeploy="true">
</Host>
uj5u.com熱心網友回復：
host中的name地址不應該是一樣的嗎？只是專案名稱不同而已
uj5u.com熱心網友回復：
哪你說說你的兩個war包期望的訪問域名各是什么
