------------------------------------------------------------------
After some discussion with Trygve I tried using a wrapper script around the JSW
script. This seems to work because ulimit and other environment properties are
inherited when spawning the new shells. This solves my problem without adding
more responsibility/pollution/noise to the appassembler and seems like better
than my patch.
A wrapper script can look something like:
(remember to enable maven filtering to resolve properties from the pom)
#!/bin/sh
# The following two lines are used by the chkconfig command. Change as is
# appropriate for your application. They should remain commented.
# chkconfig: 2345 20 80
# description: ${pom.name}
echo 'Running wrapper for ${pom.name}'
if [ "$1" = "start" ] || [ "$1" = "console" ]; then
ulimit -n 65000
echo "ulimit set to $(ulimit -n)"
fi
echo 'Calling JSW script'
exec ${rpm.path}/bin/${rpm.appname} $1
The issue can thus be converted to a documentation issue.
