Hi,
I didn't know about DCEVM. Thanks for sharing.
In my poor old development machine I am employing hot-deploy on tomcat.
This works nicely because my webapp has zero initialization cost and the
time is actually consumed on war zip/copy/unzip. We are talking 7sec vs
21sec differences.
Here is the script I use. Your mileage may vary. Also take into account
that you will need some iterations to make sure that it actually hot
deploys in tomcat as it is more fragile than reploy. And AFAIR there was
also a tomcat configuration variable that enables hot deploy but I
cannot remember details.
Hint: Put some logs in the constructor of your service so that you know
the redeploy is triggered.
---- cut here hot-deploy.sh ----
#!/bin/sh -e
TOMCAT=$HOME/tomcat;
WEBAPPSDIR=$TOMCAT/webapps;
LOGDIR=$TOMCAT/logs;
WEBAPP=sn;
LOG=$LOGDIR/$WEBAPP.log;
[ -d war ] || { echo "Cannot find war directory" >&2; exit 1; }
prev_line=`tail -n 1 $LOG`;
rsync -av war/ $WEBAPPSDIR/$WEBAPP;
[ "$1" = "-n" ] && exit 0;
touch $WEBAPPSDIR/$WEBAPP/WEB-INF/web.xml;
#echo $prev_line;
while : ; do
next_line=`tail -n 1 $LOG`;
/bin/echo -ne ".";
sleep 1;
[ "$prev_line" = "$next_line" ] || break;
done;
echo "";
#echo $next_line;

@David I improved the productivity using DCEVM

server side code is modified. There are another alternatives, but this
is free.

The nice thing about DevMode was that if you made client
changes that you could test them straight away without a
redeploy. (We are using -noserver because our server is Jboss
Fuse).
I will need to rebuild and redeploy the application now for
every client code change (or am I understanding this wrongly ?)
You understand it wrong. When you make a client code change you
hit the recompile bookmarklet of SuperDevMode (which you can drag
in your browser's bookmark bar) to trigger a recompile of your
app. After the app is recompiled the page reloads automatically
and you will see the changes. You only need to redeploy if you
make server changes. When you activate SDM through its bookmarklet
all client side code will be downloaded from the SDM code server
and not from your Jboss Fuse server.
With GWT 2.6 the recompile time may take some time (its similar to
a -draft compile)...how long that greatly depends on your app.
However GWT trunk already has initial support for
incremental/modular compilation. With incremental compilation
turned on GWT will only recompile the GWT modules in which you
have made changes and the ones that depend on them. So to make
best use of incremental compilation your app should consist of
multiple smaller GWT modules instead of a single large one.
