To be clear, use the naming convention mom##1.2.0.war and you'll get
what you want. You don;t have do have multiple versions for this to work.

As has been said before:
1. Create a directory
This should be outside of the appBase for the host you're deploying on.
This should also not be in a place where a web server can serve content
(see below).
2. Add all the war files
mom-1.1.0.war
mom-1.2.3.war
mom-5.7.9.war
3. Create a mom.xml file
In the mom.xml file, have a context element. It should read something
like the following:
<Context docBase="/your-directory/mom-1.2.3.war"/>
That's it. No reloadable="true", no debug="0", no crossContext="false".
reloadable="true" is not recommended for production environments, there
is no debug attribute, and crossContext="false" is the default.
4. Place the file in the appropriate spot.
$CATALINA_BASE/conf/[hostname]/mom.xml is where it goes.
The above configuration will serve mom-1.2.3.war as context mom for that
host when accessed from Tomcat.
And no, hacking server.xml, adding a path attribute to the context.xml
file (mom.xml file), and other such games will either not work or cause
you nothing but grief.
Note on the above.
Do NOT place this war file where Apache HTTPD (or another web server)
can serve the content directly. If it's a WAR file, the user will get to
download a copy of the application. If it's an exploded WAR file
(directory, etc.) then JSP files will get served as source (most
likely), and anything in WEB-INF will be served by the web server unless
you've taken special precautions.
Just follow the instructions in the Tomcat documentation.
. . . . just my two cents.

My client has application archives files which all have version string in it as stated below :-
eg:- mom-1.2.0.war, mom-1.3.0.war, mom-1.4.0.war, mom-1.5.0.war
So they doest want the version string mentioned in the application archive to become part of application context.
The context should remain same irrespective of the application archive they deploy,
Do you have any better approach /suggestion for this requirement
thanks for your help

Thanks charles for your time, will try out your proposed solution
++++++++++++++++++++++++++++++
If you can't get that changed, your best alternative is to keep the .war file completely outside of Tomcat's directory structure, and place a <Context> element in the file conf/Catalina/[host]/[appName].xml, with a docBase attribute pointing the absolute location of the .war file.
++++++++++++++++++++++++++++++++
Thanks

The path attribute is not allowed, except when using the strongly discouraged mechanism of placing the <Context> element in server.xml.

Your user has a nonsensical requirement. If you can't get that changed, your best alternative is to keep the .war file completely outside of Tomcat's directory structure, and place a <Context> element in the file conf/Catalina/[host]/[appName].xml, with a docBase attribute pointing the absolute location of the .war file.

That is seriously not recommended. Use the approach outlined above instead.

On a side note, did you see any debug attribute in the documentation for the <Context> element? Since you didn't, why are you using it?

Thanks a ton charles for passionatly explaining me the intrinsic things , it means a lot to me...
1> What sense does it make to statically defining a Context in server.xml ??
2> Just to confirm , so using we cannot override the default application context using "/META-INF/context.xml" ??
3> As i have a user requirement that they want to have a application context as different from application archive file name , so i can achieve
this by adding the below snippet in server.xml, provided the docBase location shouldnt be the same as of Tomcat WebApps Directory
to avoid double deployment . correct ??
<Context path="/tests" docBase="/var/www/test_application1/"
debug="0" reloadable="true" crossContext="false">
</Context>
Thanks Again

And you completely ignored this wording in the description of the path element:
"This attribute must only be used when statically defining a Context in server.xml. In all other circumstances, the path will be inferred from the filenames used for either the .xml context file or the docBase."

Pardon me if i am annoying , but from the below mail link, i located the snippet(mentioned below) in which its written
that we can define application context in context.xml.
******************************************************************************
Individual Context elements may be explicitly defined:
In an individual file at /META-INF/context.xml inside the application files. Optionally (based on the Host's copyXML attribute) this may be copied to $CATALINA_BASE/conf/[enginename]/[hostname]/ and renamed to application's base file name plus a ".xml" extension.
******************************************************************************
but wrong i am doing , in defining the context in META-INF/context.xml as follows :-
<Context path="/app1" privileged="true"/>
Does we cannot override the default application context in tomcat 6.0 using META-INF/context.xml ????
Thanks all,
Vicky

Re: Context root query
Posted by vi...@yahoo.co.in.
Helo,
Yes , i restarted tomcat after that but that doesn't help.
But if i define the following in server.xml , i am able to override the default context root of an application successfully
<Context path="/tests" docBase="/var/www/test_application1/"
debug="0" reloadable="true" crossContext="false">
</Context>
But this is not the appropriate way as i don't want to touch the tomcat server.xml for every application
Please suggest how i can override the context root of an application using META-INF/context.xml
Thanks for your time,
Vicky

Apologies:
That was a correct answer, but not to your question.
