Hi Maheshakya,
I am trying to build the CEP by sourceas [1].it was built without
errors.But when i run the ./wso2server.sh i got his error
JAVA_HOME environment variable is set to /usr/local/java/jdk1.8.0_51
CARBON_HOME environment variable is set to
/home/mahesh/GSOC/WSO2/product-cep/modules/distribution

Error: Could not find or load main class org.wso2.carbon.bootstrap.Bootstrap
do i need some additional libraries there?Is it allright to go wit the [2]
as we will be doing changes to source.
BR,
Mahesh.
