I've clean installed Eclipse 3.1.1 and WTP 1.0.1 maintenance release.
It migrated a couple of Web projects I have. When I add the projects to
a Tomcat 5.5 server definition and start it, the contexts are invoked
twice each. One of the apps fires up the Dumbster fake email server and
the other starts several threads to handle requests. Both have logging
turned on so I see both start twice.
Has anyone else seen this behavior? If so, what'd you do to cure it? I
have several other apps that I'd like to add to the server that run in
other contexts, so the doubled work load is not a good thing.
Thanks,
Cary

I left the "Run modules directly from the workspace" checked like all of
my other installations. It's publishing the projects into the
workspace's .metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps
directory. I looked in the server.xml generated for this server and it
put the <Context>s in only once.

Starting with WTP 1.0, projects are published to Tomcat's CATALINA_BASE
"webapps" directory. With the default configuration of Tomcat, this
guarantees you will get one context served using the apps directory
name. At the moment, the Tomcat support uses the project name to
publish the app, so if you specified a different context-root in your
project, then the resulting <Context> element added to server.xml will
invoke another context using the context-root. For now, the simplest
way to avoid this is to keep the project name and the context-root the
same. If this approach can't be used, you can turn off auto-serving by
setting in the server.xml:
<Host deployOnStartup="false" autoDeploy="false" ...>
This will disable auto-serving of the "default" ROOT webapp. Adding the
following context to server.xml should bring it back:
<Context docBase="ROOT" path="" reloadable="false"/>
Reloading shouldn't be needed since it doesn't change.
HTH,

Yep, that was it. I have my projects named with long, readable names

While the topic is current, what prevents the Tomcat server def from
using the context root specified in .components? I know there's always
the special case of having an empty one. Are there others?
BTW, am I the only one that runs apps frequently without a context root?
The Glassfish and Geronimo plugins have real difficulty with that.
Thanks for the pointers,

This behavior is a side effect of the ".deployables" directory (from WTP
0.7) going away, and which hasn't been properly addressed yet in WTP
1.0. It's on my to-do list to check for an existing bug and enter one
if there isn't one already. Also on the to-do list is to think about
how it should be addressed. There may be enough reasons that webapps
shouldn't be published to the "webapps" directory.
As for your question, WTP should be using the context-root from
..components. In 0.7x, specifying "" as was supported. That webapp
would take precedence and "replace" the ROOT webapp that is there by
default. Regrettably, I haven't had time to test if this still works in
WTP 1.0.
Cheers,
Larry

which you would expect. In the server.xml, the context has this path

It does, in fact, replace the default ROOT web app; I've been running
some real world tests on it. So, that part is working in 1.0.x....
BTW, the latest maintenance drop has done wonders for performance. I
recommend everyone that was have performance issues with 1.0 update
immediately.
Thanks for your help.

Just a follow up on the context root. It must have worked be it was set
that way before the 1.0 install. If you type anything in the property
page's Context Root field, it will not let you set it empty. I'll look
to see if there's a bug open on this and open one if not.
