WSO2 Enterprise Integrator 6.0.0 unable to find snappy-java jar

Question

Following the quick start guide in https://docs.wso2.com/display/EI600/Quick+Start+Guide

Since I am using Windows, I have downloaded snappy-java and put into \wso2\analytics\lib but the exception as below still occurs when starting the EI analytics

I am suspecting the guide is placing the jar at incorrect path, in previous version ESB 5.0.0, the path is in \repository\components\lib as given by https://docs.wso2.com/display/ESB500/Quick+Start+Guide

Answer 1

The right path is EI_HOME\lib . When you see "starting polling event receivers" and the error does not appear,it works. Then you can go on. :)
