In Prod env Java batch Fails sometimes with NoClassdeffoundError due to class not found exception. Occurres atleast once in a day or a week

I am facing NoClassdeffoundError due to class not found exception for Java batch application.jar files are deployed on the windows server these batch jars are getting executed via bat file from Tivoli job schedular .But I am totally clueless why it is occurring only some times in a day or in week.This issue is not coming on QA Environment but on production it occurring.My logs are as follows

The javafx.application.Application class is going to be found in a javafx library; in an IDE such as eclipse you generally configure a project to refer to those libraries it needs for compilation and execution. When you put your code into a jar and run it outside the IDE, you need to provide the library to the runtime a different way.
A standard way to do this is to set a classpath which has references to both the application jar and to any libraries it needs; the DOS command to do this would look something like:
set classpath=c:\myProjects\myApplication\myJar.jar;c:\java\libaries\javafx\jfxrt.jar
and then java would have access to the classes in both those jar files

Oracle JDK includes JavaFX on the classpath from version 1.8 onwards; if you upgrade your JDK to version 8 or later it should run. I do not recommend building production-level JavaFX applications with versions prior to Java 8 anyway.
If you really do want to use Java 7, consider using the built-in JavaFX deployment tools to build the jar, instead of the vanilla "create executable jar" from eclipse. These will properly build a jar file that includes the FX runtime, if needed. The easiest way to do this in Eclipse is to install e(fx)clipse (an Eclipse plugin); there's a tutorial which includes steps to build the jar file.

You must install the troublesome program to a folder without spaces in the full name.
