Problems getting grails running

[peterhk]

Hi,

I want to install Neflix-Ice to monitor my AWS costs.

I am using AWS Linux AMI
grails-2.2.1
java version "1.7.0_55"

echo $JAVA_HOME
/usr/lib/jvm/jre

echo $GRAILS_HOME
/opt/grails

alternatives --display java
java - status is manual.
link currently points to /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

ls -al /usr/lib/jvm
jre -> /etc/alternatives/jre

Error:
General error during semantic analysis: unable to locate the java compiler com.sun.tools.javac.Main, please change your classloader settings

java.lang.ClassNotFoundException: unable to locate the java compiler com.sun.tools.javac.Main, please change your classloader settings

Thanks for Help
