How to Run a shell script from Perl script in Parent shell?

Hi Perl/UNIX experts,

I have a problem in running a shell script from my perl script (auto.pl).

I run the perl script using
perl auto.pl
from the shell prompt

The shell script picks the files in "input" folder and procesess it.

The shell script blue.sh has this code.

Code:

export JAVA_HOME=/opt/j2sdk1.4.2_02
export PATH=${JAVA_HOME}/bin:${PATH}
export MANPATH=${JAVA_HOME}/man:${MANPATH}
export RUNPATH=:.:/export/home/lib/activation.jar:/export/home/lib/commons-dbcp-1.1.jar:/export/home/lib/jdbc2_0-stdext.jar:/export/home/lib/libmqjbnd05.so:/export/home/lib/postcard.jar
export RUNPATH=$RUNPATH:/export/home/lib/ant.jar:/export/home/lib/commons-logging-api.jar:/export/home/lib/jms.jar:/export/home/lib/log4j-1.2.8.jar:/export/home/lib/providerutil.jar
export 
java -classpath $RUNPATH placeOrders ./input/

I tried to run this in perl script using
exec("blue.sh")
exec("./blue.sh")
`./blue.sh`
`sh blue.sh`

I get this error - ./blue: JAVA_HOME=/opt/j2sdk1.4.2_02: is not an identifier

But if i run it manually from the shell

Code:

./blue.sh

the script runs fine.

I guess the problem is because perl spawns a new shell.
