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.

NAME
build-jar-repository - create a symbolic link to a JAR SYNOPSIS
build-jar-repository [OPTION]... DIRECTORY JAR|artifact-coordinates DESCRIPTION
Build a JAR repository in the named directory by copying files or creating symbolic links. The JARs can be identified by their names or Maven artifact coordinates. Artifact coordinates specify Maven artifact and are in format groupId:artifactId[:extension[:classifier]]:version. If extension is omitted then "jar" is used. If classifier is omitted then empty classifier is used. For more information see XMvn Configuration Reference. OPTIONS
If no option is specified the default action will be to create symbolic links -c, --copy Copy files. -h, --hard Create hard links. -p, --preserve-naming Try to preserve the names of the original JAR files (in case of a nested hit the slashes in the path will still be replaced by underscores). Using this option makes any future automated repository rebuild impossible, and implies -c unless specified otherwise. -s, --soft, --symbolic Create symbolic links (default). --help Display help text EXAMPLES
build-jar-repository . jndi - This will create a symbolic link to the jndi JAR in the current working directory. build-jar-repository -h /tmp log4j - This will create a hard link to the log4j JAR in /tmp directory. build-jar-repository -c . org.apache.commons:commons-io - This will copy commons-io JAR to the current working directory.
