Remove all the old files you no longer want:
$CATALINA_BASE/webapps/test.war
$CATALINA_BASE/conf/Catalina/localhost/test.xml
$CATALINA_BASE/conf/Catalina/localhost/sg#server#test.xml


Andy: Yes, I have deleted all the unnecessary war files as well as the xml
files.


Rename your WAR to sg#server#test.war

Place your renamed war in:
$CATALINA_BASE/webapps/

Any META-INF/context.xml will be extracted to:
$CATALINA_BASE/conf/Catalina/localhost/sg#server#test.xml

Andy: Yes, there is a file under my unpackaged sg#server#test.war. The file
is /usr/local/apache-tomcat/webapps/sg#server#test/META-INF/context.xml and
its content is:

<Context path="/test" debug="99" reloadable="true"
    antiJARLocking="true" antiResourceLocking="false">

    <!--Resource name="jdbc/moneysend" auth="Container"
type="javax.sql.DataSource"
              maxActive="100" maxIdle="30" maxWait="10000"
              driverClassName="oracle.jdbc.driver.OracleDriver"
              username="MS3_STL" password="password"
              url="jdbc:oracle:thin:@192.168.0.37:1521:MS3"
              defaultAutoCommit="true" removeAbandoned="true"
              removeAbandonedTimeout="60" logAbandoned="true"/-->
</Context>

I noticed that the context path is still /test. I have removed path="/test"
from the Context element. I done the same for
/usr/local/apache-tomcat/conf/Catalina/localhost/sg#server#test.xml and
restarted Tomcat.


Under catalina.log, I saw new errors:

As stated in the docs for the context element, you should not specify
the path attribute in this case.

If Tomcat finds:
$CATALINA_BASE/conf/Catalina/localhost/sg#server#test.xml

It expects to find a matching war
$CATALINA_BASE/webapps/sg#server#test.war
or directory
$CATALINA_BASE/webapps/sg#server#test
