在做别的事情时，我添加了一个名为catalina.jar的lib文件夹。这使我能够提供静态内容（可以工作），但我以前正在使用的struts动作（通过休眠访问数据库）不再有效。发生在Tomcat启动失败的第一个迹象：Tomcat服务器异常 - java：comp没有绑定在这个上下文中
SEVERE: Null component Catalina:type=DataSource,path=/,host=localhost,class=javax.sql.DataSource,name="jdbc/UpdatableDB"
随后的故障发生在运行的访问数据库的操作：
ERROR [http-8080-1 14:21:29,789] (DatasourceConnectionProvider) - Could not find datasource: java:comp/env/jdbc/UpdatableDB

为什么会增加一个罐子原因？我能做些什么（不要只是摆脱catalina.jar）？
我在网上找到的一些建议包括删除源文件中的命名common.jar，命名factory.jar和命名resources.jar - 但我已经没有这些文件。
在吉姆·加里森的要求，继承人那里JDBC/UpdatableDB绑定到数据源 - 它不是在server.xml中，其在context.xml中，这一直为我们一个很长的时间：
<Resource name="jdbc/UpdatableDB" auth="Container" type="javax.sql.DataSource"
maxActive="75" maxIdle="40" maxWait="1000"
removeAbandoned="true" removeAbandonedTimeout="300"
timeBetweenEvictionRunsMillis="30000"
defaultAutoCommit="false"
username="XXXX" password="XXXX" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://<HOSTNAME AND PATH>?autoReconnect=true"
connectionProperties="autoReconnect=true;cachePrepStmts=true;cacheCallableStmts=true;cacheServerConfiguration=true;useLocalSessionState=true;elideSetAutoCommits=true;alwaysSendSetIsolation=false;enableQueryTimeouts=false;"
/>
显示server.xml的相关部分，其中jdbc/UpdatableDB绑定到DataSource – 2010-10-27 21:35:09
我不再需要这个问题的答案 - 我摆脱了catalina .jar（最有可能在其他地方重复加载）并使用默认操作来加载静态内容。 IntelliJ抱怨说它找不到默认的动作，但我应该忽略它，而不是通过Javaland进行漫长的跋涉。尽管有警告，它仍然有效。 – 2010-10-27 22:16:24
