I think the WTP approach with the temporary tomcat installation is
very good because you can defined which projects should be started
with this tomcat, if you use one tomcat with sysdeo then all webapps
will always be starte.

Betreff: Re: My crap development environment
Sysdeo's plugin is no silver bullet, but I keep evaluating
alternatives and so far I haven't found anything better. The most
common gotchas with Sysdeo is installing devloader (which you will
need) and maintaining the set of libraries to load (for which
sysdeo-tomcat-plugin is used), setting the context path correctly and
making sure you don't have servlet-api loaded with the devloader. I
have developers asking about these over and over again.

I'll have to try the sysdeo plugin again. I used to use it
but at some
point I decided I preferred the WTP plugin (I don't quite
remember now
the reason). In any case, it's very possible it takes 45 seconds in
the initial build/publish if he has a slow disk or a large set of
libraries to copy over. After the initial build, however, it should
take a second or so to copy over any incremental changes
(that's why I
think he has an incremental builder problem).

Oh ok. Yea I never understood why WTP went with that approach.
There's
gotta
be some file locking issues though if that takes 45 seconds -
luckily
I'm on
Linux so I don't care. I use Sysdeo's Tomcat plugin that runs
everything in-place (I have Jetty as well but don't see much of a
difference in performance either way). And now with Discursive's
sysdeo-tomcat-plugin
it's
ah all so nicely automated.

When using eclipse Web Standard Tools, eclipse sets up
a temporary
Tomcat (or other app server) directory with
configuration and your
project files. Tomcat is then started from this
directory. This is
done so you can have more control of when your changes
appear in
Tomcat. You can have it set so every time it detects changes in
your build it copies the affected files to the temporary
directory, or you can have it so you publish manually
(For example
I have auto-build enabled so I don't necessarily want tomcat
restarting every time it detects a change, so I publish
manually
after I have made the set of changes I want). So basically
"Publishing" involves just synchronizing the files tomcat sees
with the contents of your eclipse biuld directory.

Just out of interest, what's this publishing step?
Compilation
is
the
only
thing and occasional re-load of the context when hotswapping
fails
(like
it
does with Tomcat most of the time) that should be
required. If
you
do
something else, I think you haven't set up your environment
correctly
for
development.

I really don't think the Jetty plugin is going to solve his

in

willing
to
bet that his problem is due to an incremental compile issue
where
his
entire project is re-compiled every time he saves one file.
He's talking about 60 seconds before the server even begins
starting
up. I
had this issue while using the AJDT plugin in
combination with
Maven
because maven uses 2 output directories by default (one for
the
test
classes) and AJDT didn't handle this properly triggering a
complete
rebuild. There is no reason it should take 15
seconds to SAVE
an
.html
file (Jetty plugin won't speed that up). From his
numbers it
looks like after saving/compiling/publishing tomcat
starts up
in less
than
10 seconds which sounds completely reasonable
depending on his
application's initialization requirements.
Saving a .java file: 15 seconds Saving a .html file: 15
seconds Saving a .jwc file: 28 seconds
Stopping the tomcat server: 2 seconds (acceptable)
Publishing
to the tomcat server: 45 seconds Starting the tomcat server:
54 seconds (it insists on publishing
first)

If you want to use Jetty 6 then you can't use

but
you
can
launch from Eclipse easily enough just by

import org.mortbay.jetty.handler.DefaultHandler;

import org.mortbay.jetty.nio.SelectChannelConnector;
import org.mortbay.jetty.webapp.WebAppContext;
public class JettyLauncher {
public static void main(String[] args)
throws Exception {
String path = (args.length > 0 ?
args[0] : "web");
Server server = new Server();
Connector connector = new
SelectChannelConnector();
connector.setPort(8080);
server.setConnectors(new Connector[] {
connector
});
HandlerCollection handlers = new
HandlerCollection();
ContextHandlerCollection contexts = new
ContextHandlerCollection();
handlers.setHandlers(new Handler[] {
contexts, new
DefaultHandler() });
server.setHandler(handlers);
new WebAppContext(contexts, path, "/");
server.setStopAtShutdown(true);
server.setSendServerVersion(true);
server.start();
server.join();
}
}

Murray,
I really enjoyed using Jetty with the
Eclipse startup
plugin on a project I did a while back. I
would highly
reccomend abandoing tomcat for development and using
Jetty during your development. If you have
dependencies
to tomcat functionality you might want to mock it out
during dev., it will definetly save you time.
Get the
Jetty
plugin
and I think you'll have alot of your issues resolved.
best,
-dh

Hi all

Does everybody else experience these delays
or is it
just
me?
It was suggested that I use maven2 -
however I looked
through
the
maven2 flash presentation and it didn't mention
anything
about making
my development work in Eclipse faster - it was more
focused
on pulling
dependencies and easing the build process.
And if I
were
to install
maven2 would it change any of the above anyway???
