How to delete an application from Tomcat?

[elektrophyte]

I'm using Tomcat 5.5.9 on Windows 2000, and IntelliJ IDEA. I started
getting "no suitable driver" errors. (The driver --
mysql-connector-java-3.1.8-bin.jar -- is present in "C:\Program
Files\Apache Software Foundation\Tomcat 5.5\common\lib". It's also in
my webapp's WEB-INF/lib directory.)

I decided to clear my app out of Tomcat and redeploy it fresh. That's
worked before to solve the driver problem.

Shut down Tomcat, deleted "TOMCAT_HOME\webapps\agenda". I noticed that
there is also "TOMCAT_HOME\work\Catalina\localhost\agenda" and I
deleted that to.

Restarted Tomcat and my app "agenda" shows up in the listing in the
Tomcat manager. How is that possible? How can I get rid of it? Do I
need to reinstall Tomcat? Do I need to replace the entire computer?

The app shows up in the listing but clicking on the name returns a 404
error. Clicking on "start" returns "FAIL - Application at context path
/agenda could not be started" and clicking on "undeploy" returns "OK -
Undeployed application at context path /agenda".

The app has reappeared in "TOMCAT_HOME\work\Catalina\localhost\agenda".

Thanks,

E

Try editing the server.xml to remove it, or undeploy it from the Tomcat
manager.

Hi,

I'm using Tomcat 5.5.9 on Windows 2000, and IntelliJ IDEA. I started
getting "no suitable driver" errors. (The driver --
mysql-connector-java-3.1.8-bin.jar -- is present in "C:\Program
Files\Apache Software Foundation\Tomcat 5.5\common\lib". It's also in
my webapp's WEB-INF/lib directory.)

You probably should put the driver in javasdk/jre/lib/ext folder.

I decided to clear my app out of Tomcat and redeploy it fresh. That's
worked before to solve the driver problem.

Shut down Tomcat, deleted "TOMCAT_HOME\webapps\agenda". I noticed that
there is also "TOMCAT_HOME\work\Catalina\localhost\agenda" and I
deleted that to.

It should ne easier to just go to the Tomcat Manager and "undeploy" it. Note
if the app is residing in the tomcat/webapps folder, the whole folder will
be deleted.

Restarted Tomcat and my app "agenda" shows up in the listing in the
Tomcat manager. How is that possible? How can I get rid of it? Do I

There is no need to reinstall Tomcat. Look also at
tomcat/conf/Catalina/localhost folder.

The app shows up in the listing but clicking on the name returns a 404
error. Clicking on "start" returns "FAIL - Application at context path
/agenda could not be started" and clicking on "undeploy" returns "OK -
Undeployed application at context path /agenda".

Because the actual location of the app has been deleted.

The app has reappeared in "TOMCAT_HOME\work\Catalina\localhost\agenda".

This folder is for Tomcat to put the compiled jsp file.

Thanks,

As mentioned in my post, I did undeploy it from the Tomcat manager.

Edit server.xml?? There's nothing regarding the app in that file.
Should there be?

My question is, if I delete all app related directories from the Tomcat
hierarchy, how does it show up in the Tomcat manager application
listing after I restart Tomcat? Where is the residue of this
application hanging on?

Thanks for the reply.

I'll give that a try. There seem to be many different opinions about
where jar files go in Tomcat. That's one. I've also heard...
WEB-INF\lib
TOMCAT_HOME\common\lib
TOMCAT_HOME\common\endorsed
There's also a "TOMCAT_HOME\shared" directory in the disribution that
looks pretty enticing.

Tried that (see original post).

tomcat/conf/Catalina/localhost folder.

Nothing related to my application is in that directory. What is
supposed to be found there?

There are three ways webapps can reside in tomcat:

defined in : conf/server.xml

defined in an xml file in tomcat/conf/Catalina/localhost/

or as a folder or a .war file in tomcat/webapps


btw : Have you tried to kill the cache? shutdown, delete all content in
tomcat/work and restart

Maybe you can do a word search on the tomcat folder, that relates to your
application, to look for the "residues".

If you mean restart Tomcat then yes, I did try that. I didn't try
restarting the machine.

I'm accustomed to copying my webapp as an expanded directory into
TOMCAT_HOME/webapps. The app is "defined" (if I understand you
correctly) in TOMCAT_HOME/webapps/CONTEXT_PATH/WEB-INF/web.xml.
