i searched stackoverflow for any solution to a similar error, but i didn't find any, any solution suggested to fix this ?

Instead of :
return ResponseEntity.ok(hospitals) ;
Try this :
return ResponseEntity<List<hospitals>>(hospitals);

In this code when we call the Service using restTemplate.exchange() it gives me the error below. I am using Spring framework 4.0.1.

So, what am I doing wrong?

You didn't defined any strategy to your generated id for message.
By default, Hibernate will check on your database to find any sequence or strategy to generate values. Try this :
#GeneratedValue(strategy = GenerationType.IDENTITY)

How to return text_html type response in Jersey

I am developing a REST API using jersey jax-RS. This consumes data in JSON format and produces the output in html format.
When I set the MediaType for #Produces as TEXT_HTML and #Consumes as #APPLICATON_JSON and requested the 'GET' query on POSTMAN REST client, it gave me the following error:
org.apache.catalina.core.StandardWrapperValve invoke

On searching about this on the internet, I did not come across any useful solution except it was mentioned to download the genson jar and add it. After adding it as external jar in Eclipse (Java EE) MAVEN Project, it still gave the same exception which I guess is due to the fact that this jar is for json MediaType and is not used in the context of html content type.
Basically, I want to produce the content as HTML. How can I do it? I am entirely new to Jersey and the concept of REST API.

The class that retrieves the Hibernate Session from HibernateUtil Class.
package com.project.util;
import javax.faces.application.FacesMessage;
import javax.faces.application.FacesMessage.Severity;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;
public class FacesUtil {
public static Object getRequestAttribute(String name) {
FacesContext cxt = FacesContext.getCurrentInstance();
ExternalContext ecxt = cxt.getExternalContext();
HttpServletRequest request = (HttpServletRequest) ecxt.getRequest();
return request.getAttribute(name);
}
}
package com.project.util;
import java.io.Serializable;

public class Repositorio implements Serializable {
/**

private static final long serialVersionUID = 1921518600016820244L;
private Session getSession() {
return (Session) FacesUtil.getRequestAttribute("session");
}
}
I'm passing the session value to the app using a Servlet filter
package com.project.util;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;
import org.hibernate.Session;
import org.hibernate.Transaction;
#WebFilter(servletNames={"Faces Servlet"})
public class HibernateSessionFilter implements Filter {
#Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
Session session = HibernateUtil.getSession();
Transaction trx = null;
try {
trx = session.beginTransaction();
request.setAttribute("session", session);
System.out.println("Init ...");
chain.doFilter(request, response);
trx.commit();
System.out.println("closing ...");
} catch (Exception e) {
if(trx != null) {
trx.rollback();
}
} finally {
session.close();
}
}
#Override
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
#Override
public void destroy() {
// TODO Auto-generated method stub
}
}

Yes I'm using FacesContext.getCurrentInstance() in a class that is called inside a method with that annotation to retrieve HibernateSession. Here is the class.

Updating my answer since the error stackTrace has been provided.
StackTrace says you have a NullPointerException at UsuariosHibernate.java:22
Can you post the code for UsuariosHibernate.java?
You have a lot of flaws here. The main Culprit is Using HibernateSession instead of HTTPSession.
Import HTTPSession instead of HibernateSession in Repositorio class.
Do you have a getUsuarios(); method in Repositorio class?
Also you seem to be mixing HTTPSession with HibernateSession in
HibernateSessionFilter. HTTPSession should be imported.
Please fix these things first!
You are missing <rewrite> tag. Add the tag in pretty-config file as shown below,
<rewrite match="/pages/user/cadastro.htm" substitute="/cadastro_usuario" redirect="301"/>
