Tomcat server exception - java:comp is not bound in this Context

In doing something else, I added a jar to my lib folder called catalina.jar . This allowed me to serve static content (which works), but my previously working struts actions (which access a database through hibernate) no longer work. The first indication of failure occurs on tomcat startup:

SEVERE: Null component Catalina:type=DataSource,path=/,host=localhost,class=javax.sql.DataSource,name="jdbc/UpdatableDB"

The subsequent failures happen on running an action that access the database:

ERROR [http-8080-1 14:21:29,789] (DatasourceConnectionProvider) - Could not find datasource: java:comp/env/jdbc/UpdatableDB

Why would adding a jar cause this? And what can I do about it (without just getting rid of catalina.jar)?

Some suggestions I've found on the web included removing naming-common.jar, naming-factory.jar, and naming-resources.jar from your source - but I already don't have these files.

At Jim Garrison's request, heres where jdbc/UpdatableDB is bound to a DataSource - its not in server.xml, its in context.xml, and this has been working for us for a very long time:

<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;"
        />

In Tomcat 5.5, we used the following syntax to look up jdbc resources:

java:/comp/env/jdbc/UpdatableDB

I am not sure if that is equivalent to what you are using, but I thought I would mention it in case it helps someone else.

Even thought the original author no longer needs the answer I stumbled over a similar problem and the answer was found here JNDI lookup works fine using lookUp but not when used in persistence.xml of JPA The reason was a missing slash after java, similar to the location below:

Could not find datasource: java:comp/env/jdbc/UpdatableDB

You shouldn't be adding catalina.jar to your WEB-INF/lib because that is a container specific jar. That's why you're getting that error. Remove the jar file and add it as a Target Runtime Tomcat in eclipse
