----------------------------------------

                 Key: JBAS-8670
                 URL: https://jira.jboss.org/browse/JBAS-8670
             Project: JBoss Application Server
          Issue Type: Patch
      Security Level: Public (Everyone can see)
    Affects Versions: 6.0.0.CR1
            Reporter: Emmanuel Bernard
            Assignee: Emmanuel Bernard
            Priority: Minor
         Attachments: JBAS-8670-symlink.patch

I was working on packagin JBoss AS into homebrew (Mac OS packaging system) and found a limitation in our command scripts.
They assume that the script has not been symlinked and hence fail to find the right jars upon symlinked scripts.

Basically, they do 

{code}
DIRNAME=`dirname $0`
PROGNAME=`basename $0`
{code}

and should do

{code}
# Extract the directory and the program name
# takes care of symlinks
PRG="$0"
while [ -h "$PRG" ] ; do
  ls=`ls -ld "$PRG"`
  link=`expr "$ls" : '.*-> \(.*\)$'`
  if expr "$link" : '/.*' > /dev/null; then
    PRG="$link"
  else
    PRG="`dirname "$PRG"`/$link"
  fi
done
DIRNAME=`dirname "$PRG"`
PROGNAME=`basename "$PRG"`
{code}
