Good day,
This is the approach I use; assuming you use the war overlay method, and
linux for a development environment, this should work for you. Going
from 3.4.6 to 3.5.2 should be fairly easy.
- update the version for the cas dependencies
- run mvn dependency:resolve
- diff the two webapp jars in ~/.m2/repository/ (expected you know how a
maven repo works) by using jardiff
- make sure any of the CAS related files that you've changed are updated
with new changes. Some examples are...
- cas.properties
- deployerConfigContext.xml
- login-webflow.xml
- ticketGrantingTicketCookieGenerator.xml
- externalResources.xml
- default_views.properties
- all JSP files
A simple way of comparing the config files above, is to extract them
from the WAR, and copy them over top of our files. Then, from there, you
just need to use your favourite tool to compare. That could be eclipse,
IDEA, or svn command line. I usually do an "svn diff" and pipe it to
/usr/share/vim/vim73/macros/less.sh. Then, I use IDEA to adjust the
files in it's GUI compare tool, so that it still has my customizations,
but has all the new stuff too.
The jardiff script is below...
#!/bin/sh
function jhelp()
{
printf "Extracts two JAR files passed in to /tmp/JAR1 and /tmp/JAR2,
and compares them\n";
printf "$0 [ -k|--keep don't remove temp directories] [ -h|--help ]
jar1.jar jar2.jar\n";
}
# get the options and evaluate them
OPTS=`getopt -o kh? -l keep,help -- "$@"`
eval set -- "$OPTS"
while true ; do
case "$1" in
-k|--keep)
KEEP=true ;
shift 1 ;;
-\?|-h|--help)
jhelp ;
exit 0;
break ;;
--)
shift ;
break ;;
*)
echo "Internal error!" ;
exit 1 ;;
esac
done
JAR1=`readlink -f $1`
JAR2=`readlink -f $2`
if [ "$JAR1" = "" -o "$JAR2" = "" ]; then
echo "Two JAR arguments required"
jhelp
fi
rm -rf /tmp/JAR1 /tmp/JAR2
mkdir /tmp/JAR1 2>&1 >/dev/null
mkdir /tmp/JAR2 2>&1 >/dev/null
(cd /tmp/JAR1 ; jar -xvf $JAR1) 2>&1 >/dev/null
(cd /tmp/JAR2 ; jar -xvf $JAR2) 2>&1 >/dev/null
diff -ru /tmp/JAR1 /tmp/JAR2
if [ "$KEEP" != "true" ]; then
rm -rf /tmp/JAR1
rm -rf /tmp/JAR2
fi

Hi,
We are currently at CAS Server 3.4.6 version and using
Maven Overlay Method. Planning to upgrade to the latest version of CAS.
Can anyone please suggest the right approach. Can I upgrade straight
from 3.4.6 to 3.5.2 Release?
Thank you,
Malar
