To design Business Rules, need to install Business Rules service plugin in eclipse. As per the documentation, https://new-console.ng.bluemix.net/docs/services/rules/index-gentopic1.html#rulov002 only Eclipse Juno is supported. This plugin got installed in Eclipse Juno with Java 6 only. With higher versions of Java with eclipse Juno, plugin is not getting installed.
Also, the Bluemix plugin is not supported in Eclipse Juno.
Hence to work with this service, an user needs to switch between two eclipse versions, one is for writing business rules and other one is to write bluemix application.
