I'm not in front of a computer so this is all by memory & thus probably not exact... Go to your Preferences | Java | Installed JRE and point it at a 1.7 or 1.8 JDK. Then go to the Compiler options and set it to 1.7 or 1.8 for the workspace. Last check the Compiler options for each project in your workspace (right click each project & go to its properties). Make sure all of those are set to the same version or are inheriting from the workspace.
Last time I saw the same error, I had the Projects set for 1.8 Compiler but Installed JRE was pointed at JDK 1.5. Getting the Java version consistent everywhere should fix this (it did for me). -Kirk On Wednesday, July 15, 2015, darshan hs <[email protected]> wrote: > Hi i am trying to run helloworld sample program,However i am getting the > following error > Exception in thread "main" java.lang.UnsupportedClassVersionError: > com/gemstone/gemfire/cache/client/ClientCacheFactory : Unsupported > major.minor version 52.0 > > Kindly resolve at the earliest >
