Error: No class Def found error while setting up Java as a Windows Service

Following is the error log I'm getting:

I'm using

wrapper-windows-x86-32-3.5.25-pro

in order to make my already developed application in Spring-boot. I wanted to execute this application as a windows service but I'm not.

This problem is specific to Tanukisoftware as I'm unable to configure it.

PFB the configuration I'm using for setting up the class path here:

wrapper.java.classpath.1=../lib/wrappertest.jar
wrapper.java.classpath.2=../lib/wrapper.jar
wrapper.java.classpath.3=../lib/slf4j-api-1.7.5
wrapper.java.classpath.4=../lib/myApp.jar

even if myApp.jar contains the slf4j classpath already and its running already. I think this is library specific problem and its not finding up the classpath even if I explicitly set it like did above.

Can you please let me know how it can be solved?
