EOFException when using ObjectInputStream in Tomcat 7 - java

I am using a JApplet which passes the value through the ObjectOutputStream to connect to the database. If the value is present in the database then the JApplet will be redrawn. When I run my program in NetBeans using Tomcat 7 in browser, it runs perfectly. But when I try running the same program in the browser in the server, I am getting an EOFException in the ObjectInputStream. The following is the exception I am getting:
java.io.EOFException

Problem in creating executable jar in Eclipse

I'm working on a desktop program made in Java (Eclipse).
The program transfers data from a pdf file to a Google sheets document.
So far it works fine in Eclipse.
I'm running into problems when I'm trying to create a runable jar.
It is made as a gradle project.
