GroovyConnector class not found

Bonita BPM 5.7
Server Glassfish : 3.1.2
JDK : 1.7

We have the exception listed below while calling a groovy script connector in a task. In glassfish3\glassfish\domains\domain1\bonita-server-v5.7.2\server\default\tmp there are scripting-5.7.2.jar listed. Is there any other reference to the groovy jars? Where do we have to put the classpath references?
Thanks in advance
