How to extract String (from Java code) into HTML page?

Question

I have eclipse project (Using MyBatis and Jersey) which controls "Login page". Jersey services create two different pages, where you can see string output about events (for ex.: login created, creation error, wrong data and so on). But how can I transfer this string from java code into HTML page:

//some fancy looking HTML form
    <div class="header">
        <h1>Login Form</h1>
        <span>Some text which I want to extract from String.</span>
    </div>
//form continues

Jersey class which can create two different pages at this moment (with only string output):

package qLogin.rest;

import javax.ws.rs.*;
import javax.ws.rs.core.*;

import qLogin.validator.*;

@Path("/")
public class LoginInfo {

    @POST
    @Path("/logged")
    @Consumes("application/x-www-form-urlencoded")
    @Produces(MediaType.TEXT_HTML)
    public Response LogIn(
            @FormParam("email") String email,
            @FormParam("password") String password//,
            /*@Context UriInfo uriInfo*/) {
        LoginValid loginValid = new LoginValid(email, password);
        String output = loginValid.getHtmlAnswer();
        return Response.status(200).entity(output).build();     
    }

    @POST
    @Path("/create")
    @Consumes("application/x-www-form-urlencoded")
    public Response newCreate(
            @FormParam("email") String email,
            @FormParam("password") String password) {       
        CreateValid createValid = new CreateValid(email, password);
        String output = createValid.Outputter();        
        return Response.status(200).entity(output).build(); 
    }
}

To build html page i can use following code:

 URI uri = uriInfo.getBaseUriBuilder().path("/test.html").build();
 return Response.seeOther(uri).build();

But how do I put String output into this page?

If you want to do it server-side, you could use a templating framework/engine and produce the expected HTML output during a call to a custom MessageBodyWriter.
