Error 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.

SCRIPT(1)						    BSD General Commands Manual 						 SCRIPT(1)

NAME
script -- make typescript of terminal session SYNOPSIS
script [-a] [-k] [-q] [-t time] [file [command ...]] DESCRIPTION
The script utility makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1). If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript. If the argument command ... is given, script will run the specified command with an optional argument vector instead of an interactive shell. Options: -a Append the output to file or typescript, retaining the prior contents. -k Log keys sent to program as well as output. -q Run in quiet mode, omit the start and stop status messages. -t time Specify time interval between flushing script output file. A value of 0 causes script to flush for every character I/O event. The default interval is 30 seconds. The script ends when the forked shell (or command) exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not set) for the C-shell, csh(1)). Certain interactive commands, such as vi(1), create garbage in the typescript file. The script utility works best with commands that do not manipulate the screen. The results are meant to emulate a hardcopy terminal, not an addressable one. ENVIRONMENT
The following environment variable is utilized by script: SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most shells set this variable automatically). SEE ALSO
csh(1) (for the history mechanism). HISTORY
The script command appeared in 3.0BSD. BUGS
The script utility places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects. It is not possible to specify a command without also naming the script file because of argument parsing compatibility issues. When running in -k mode, echo cancelling is far from ideal. The slave terminal mode is checked for ECHO mode to check when to avoid manual echo logging. This does not work when in a raw mode where the program being run is doing manual echo. BSD
