Hibernate Communications Link Failure in Hibernate Based Java Servlet application powered by MySQL

Question

Let me describe my question -

I have a Java application - Hibernate as the DB interfacing layer over MySQL. I get the communications link failure error in my applic

Answer 1

I solved my communication link failure with c3p0. I came across the blog below that explained that the org.hibernate version must be equal to the c3p0 version, so this is the pom configuration that made my day

            org.hibernate
            hibernate-core
            4.3.6.Final


    org.hibernate
     hibernate-entitymanager
     4.3.1.Final
 

 org.hibernate
  hibernate-c3p0
 4.3.6.Final


  
    c3p0
    c3p0
   0.9.1.2

like he explains, it was enough to add only one property to hibernate.cfg.xml to get c3p0 pooling

no more "communication link error" , "expected to read 5 bytes,read 0" after that. here is the link:https://howtodoinjava.com/hibernate/hibernate-c3p0-connection-pool-configuration-tutorial/
