Create JSONWebService without using service builder

[Raghu k, modificado hace 10 años.]

Hi All,
I have one method which does some job. I want to expose this as a JSON web service. When I googled all I found is creating JSON web services with Service builder. But to use service builder we should define an entity in service.xml and later we need to create methods in XXX-serviceImple class. But I dont have any requirement of creating a table.
How can i achieve this?

I tried something like this but this service is not available or registered under http://localhost:8080/api/jsonws
1. Created a portlet and written a class with
package com.raghu.portal.agcoservices;

import com.liferay.portal.kernel.jsonwebservice.JSONWebService;

@JSONWebService
public class RaghuSservices {

public String sayHello(String name){
return " Hello "+ name;
}
}


2. Modefied web.xml by adding below entries. In this link Registering Plugin JSON Web Services I found we need to change web.xml like this.

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

        </servlet>
        <servlet-mapping>
            <servlet-name>JSON Web Service Servlet</servlet-name>
            <url-pattern>/api/jsonws/*</url-pattern>
        </servlet-mapping>
</web-app>

3. Deployed my portlet and checked it under */api/jsonws. I didnot find any entry for my portlet.

Hi,

I tried the same am getting the same.i think you can better to use restful webservices instead of JSONWebservices.

Hi Raghu,

Did you find any solution ?

ServiceBuilder is used for building a service. Database table is not required. Just create the entity without columns and localservice.
