@SanTiaGo_KarThiCk Can you try removing the `jdbc_driver_library` setting from your configuration and copying `mongojdbc1.6.jar` onto a location on the Logstash classpath? (`<LOGSTASH_HOME_DIRECTORY>/logstash-core/lib/jars`)

@SanTiaGo_KarThiCk I'm no MongoDB expert, but I suspect there are still some missing dependencies. I did a search for that class, and it looks like it comes from the MongoDB java driver (as opposed to the MongoDB JDBC driver). You will need to add that, plus any other dependencies that MongoDB requires to the classpath in addition to the JDBC driver you have already added.
