changing the default application

[Thomas Schweikle <tp...@vr-web.de>]

Hi!

How can I change the default application from the tomcat
"ROOT/index.jsp" page to an application installed in
"$CATALINA_HOME/Catalina/localhost/app.xml"?

I found the default application in "web.xml" and changed it from

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

to

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/tomcat</url-pattern>
    </servlet-mapping>

For the web application I defined (in
"$CATALINA_HOME/Cataline/localhost/app.xml"):

<Context
   path="/"
   docBase="/opt/app"
   debug="0"
   reloadable="false">
   <Logger
      className="org.apache.catalina.logger.FileLogger"
      prefix="mywebapp."
      suffix=".log"
      timestamp="true"/>
</Context>

but after restarting tomcat it seemd not to have any effect: calling
http://server:8080/tomcat did just not work and give back an error
404 - resource not available.

http://server:8080/ did work, but returned the tomcat default page.
My own webapp was not reachable at all.

Any idea what I am missing?

Name your application ROOT - that's your only choice.  If you use a
<Context> element in conf/Catalina/[host]/ROOT.xml, store your app
outside of the <Host>'s appBase directory and use the docBase attribute
to point to it.

You're confused.  That's the default _servlet_, not the default webapp.
That servlet is needed to deliver all static content.  Change it back to
the way you found it and leave it alone.

The path attribute is not allowed in this instance; the file containing
the <Context> element must be named ROOT.xml for it to be treated as the
default webapp.

Lots - see the above.

That's not going to help. You should probably put it back the way it
was.  That's the *default servlet* not the default application.

That also is not going to work, mostly because you're changing the wrong
application.

That's becau... see above.

You've not stated which version of Tomcat you're using, and to hazard a
guess, you're missing some quality time spent in the company of the docs.

Reply with your server version and I'll talk you through it.
