Hi Ravi, There is only one possible reason for this issue - incorrect classpath. And this thread doesn't have enough information to resolve this remotely.
I suggest you to do the following: 1. Switch to Maven. There is a very big chance it will resolve the issue right away and will also make your life much easier. 2. Use debugger to find out where the wrong class is coming from. 3. If above doesn't help, please create a project that will reproduce the problem, upload it to GitHub and provide the link here. Someone will take a look and provide a solution then. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/LOOK-THORUGH-THIS-ERROR-tp6977p7144.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
