I am currently having an issue deploying a WAR file to my Tomcat7 server (Im new to web dev with java). Everything works great in eclipse but when I generate a WAR file and deploy it to the server I get the following error. "Failed to start component []" Below is the log dump.
Caused by: org.apache.catalina.LifecycleException: Failed to process either the global, per-host or context-specific context.xml file therefore the [] Context cannot be started.

当我删除/META-INF/context.xml文件时，似乎可以正常加载，但是我无法使用数据库连接.
When I remove my /META-INF/context.xml file it seems to load just fine however I cant use my DB connection.
我的context.xml在下面.
My context.xml is below.
<context>
<Resource name="jdbc/mysitedb" auth="Container"
maxActive="100" maxIdle="30" maxWait="10000"
username="myusername" password="mypassword"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://www.mysite.com/mysitedb?autoReconnect=true"
logAbandoned="true" removeAbandoned="true"
removeAbandonedTimeout="60" type="javax.sql.DataSource" />
</context>
我是JSP的新手，所以将不胜感激.
I am new to JSP so any help would be greatly appreciated.
推荐答案
如果这确实是您完整的context.xml，则需要将其包装在Context元素中:
If that's really your complete context.xml, you need to wrap it in a Context element:
<Context>
<Resource name="jdbc/mysitedb" auth="Container"
maxActive="100" maxIdle="30" maxWait="10000"
username="myusername" password="mypassword"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://www.mysite.com/mysitedb?autoReconnect=true"
logAbandoned="true" removeAbandoned="true"
removeAbandonedTimeout="60" type="javax.sql.DataSource" />
</Context>
您的Tomcat正在尝试加载未命名的组件.可能是context.xml损坏了.对于损坏的web.xml，您可能会收到类似的错误.
Your Tomcat is attempting to load an unnamed component. Could be that broken context.xml. You can get similar errors for a broken web.xml.
