Hi Nishali, Sometimes you will get this error If you have same package name with different extension class names. Its a known error in OSGI. Please check whether you have multiple extensions in a same package. eg: org.wso2.cep.extOne and org.wso2.cep.extTwo will throw you the error when you try to deploy extTwo extension.
Thanks, Damith.
