My startup.sh is:

#!/bin/sh
# -----------------------------------------------------------------------------
# Start Script for the CATALINA Server

export CATALINA_OPTS="-Xmx512m"

# Better OS/400 detection: see Bugzilla 31132
os400=false
case "`uname`" in
CYGWIN*) cygwin=true;;
OS400*) os400=true;;
esac

# resolve links - $0 may be a softlink
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

PRGDIR=`dirname "$PRG"`
EXECUTABLE=catalina.sh

# Check that target executable exists
if $os400; then
# -x will Only work on the os400 if the files are:
# 1. owned by the user
# 2. owned by the PRIMARY group of the user
# this will not work if the user belongs in secondary groups
eval
else
if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then
echo "Cannot find $PRGDIR/$EXECUTABLE"
echo "This file is needed to run this program"
exit 1
fi
fi

exec "$PRGDIR"/"$EXECUTABLE" start "$@"


but when i start it i get:

root@xxx [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# sh -x ./startup.sh
+ $'\r'
: command not found7:
+ export $'CATALINA_OPTS=-Xmx512m\r'
+ CATALINA_OPTS=$'-Xmx512m\r'
+ $'\r'
: command not found9:
+ os400=$'false\r'
'/startup.sh: line 12: syntax error near unexpected token `in
'/startup.sh: line 12: `case "`uname`" in
root@xxx [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]#

and if i list the process:

root@xxx [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# ps aux | grep tomcat
root 6822 0.0 0.0 2044 316 ? Ss May11 0:00 jsvc.exec -user tomcat -cp ./bootstrap.jar -Djava.endorsed.dirs=../common/endorsed -debug -outfile ../logs/catalina.out -errfile ../logs/catalina.err -verbose org.apache.catalina.startup.Bootstrap -security

root 11161 0.0 0.0 4320 656 pts/0 S+ 10:51 0:00 grep tomcat

what can be the problem?
