I think you have referenced EcommerceResponse in your servlet using @3214626 annotation and EcommerceResponse is a POJO class right?
We use @Reference annotation to inject OSGi service. As EcommerceResponse is not an OSGi service and EcommerceResponse is not available in OSGi Service Registry that's why you are getting unsatisfied here.
Sharing one example here -
Employee is a POJO class here -
/**
*
*/
package com.aem.demo.core.models;
/**
* @380 debal
*
* This Employee POJO represents entity Employee
*/
public class Employee {
private String firstName;
private String lastName;
private String designation;
/**
* @90521 firstName
* @90521 lastName
* @90521 designation
*/
public Employee(String firstName, String lastName, String designation) {
this.firstName = firstName;
this.lastName = lastName;
this.designation = designation;
}
/**
* @2007960 the firstName
*/
public String getFirstName() {
return firstName;
}
/**
* @90521 firstName the firstName to set
*/
public void setFirstName(String firstName) {
this.firstName = firstName;
}
/**
* @2007960 the lastName
*/
public String getLastName() {
return lastName;
}
/**
* @90521 lastName the lastName to set
*/
public void setLastName(String lastName) {
this.lastName = lastName;
}
/**
* @2007960 the designation
*/
public String getDesignation() {
return designation;
}
/**
* @90521 designation the designation to set
*/
public void setDesignation(String designation) {
this.designation = designation;
}
}
Interface -
/**
*
*/
package com.aem.demo.core.services;
import com.aem.demo.core.models.Employee;
/**
* @380 debal
*
* This service is responsible to store Employee From Data into AEM
* repository
*
*/
public interface WriteEmployeeData {
public void storeEmployeeData(Employee employee);
}
Service Impl -
/**
*
*/
package com.aem.demo.core.services.impl;
import java.util.HashMap;
import java.util.Map;
import java.util.Objects;
import org.apache.sling.api.resource.LoginException;

public class WriteEmployeeDataImpl implements WriteEmployeeData {
private final Logger logger = LoggerFactory.getLogger(WriteEmployeeDataImpl.class);
@Reference

Map<String, Object> map = new HashMap<String, Object>();

try {

logger.info(" Resource Name {}", employeeData.getName());
resourceResolver.commit();
} catch (PersistenceException pe) {

} catch (LoginException e) {
logger.error("Could not get service user [ {} ]", "demoSystemUser", e.getMessage());
}
return serviceResourceResolver;
}
}
Now I have used Employee class in my sling servlet here -
/**
*
*/
package com.aem.demo.core.servlets;
import java.io.IOException;
import javax.servlet.Servlet;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.HttpConstants;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.aem.demo.core.models.Employee;
import com.aem.demo.core.services.WriteEmployeeData;
import com.google.common.base.Strings;
/**
* @380 debal This servlet will be invoked during Employee Form submission
*
*/
@Component(service = Servlet.class, property = { "sling.servlet.paths=" + "/bin/employeeForm",
"sling.servlet.methods=" + HttpConstants.METHOD_POST })
public class EmployeeFormServlet extends SlingAllMethodsServlet {
private final Logger logger = LoggerFactory.getLogger(EmployeeFormServlet.class);
/**
*
*/
@Reference
WriteEmployeeData writeEmploeeData;
private static final long serialVersionUID = -3743088247910006615L;
protected void doPost(SlingHttpServletRequest slingHttpServletRequest,
SlingHttpServletResponse slingHttpServletResponse) {
String employeeFname = slingHttpServletRequest.getParameter("fname");
String employeelname = slingHttpServletRequest.getParameter("lname");
String employeeDesignation = slingHttpServletRequest.getParameter("designation");
logger.info("**** Employee First Name ***** {}", employeeFname);
logger.info("**** Employee Last Name ***** {}", employeelname);
logger.info("**** Employee Designation ***** {}", employeeDesignation);
if (!Strings.isNullOrEmpty(employeeFname) && !Strings.isNullOrEmpty(employeelname)
&& !Strings.isNullOrEmpty(employeeDesignation)) {
Employee employee = new Employee(employeeFname, employeelname, employeeDesignation);
writeEmploeeData.storeEmployeeData(employee);
try {
slingHttpServletResponse.sendRedirect("/content/demo/us/en/reports.html");
} catch (IOException e) {
logger.error(" Unable to submit Form {}", e.getMessage());
}
}
}
}
Please focus on Employee part only.
Hope this will help.
