Hi @ashwinikhaple 

Please see below:

 

public class MyServlet extends SlingAllMethodsServlet {

private static final long serialVersionUID = 1L;

@Reference
private transient MyService myservice;

@Override
protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {

myservice.anything();

}
}

Hope this helps!
Thanks!

        Hi, @ashwinikhaple,

         

        If you are using SCR annotation, you can use @Reference annotation to inject the service into the servlet.

        Something similar to this.

        @Reference
MyService service;

        You can refer to the below thread for more details.

        https://stackoverflow.com/questions/56732548/aem-6-4-x-osgi-servlet-how-to-access-an-osgi-service-from-a-servlet

         

         If you are using R6 annotation, Please refer to below URL for the same.

          Hello @rohit_utreja Thank you for the reply. I have created servlet below how can I call MyService here?

          import javax.servlet.Servlet;
          import javax.servlet.ServletException;
          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.SlingSafeMethodsServlet;
          import org.osgi.framework.Constants;
          import org.osgi.service.component.annotations.Component;

          @Component(service = Servlet.class,
          property={
          Constants.SERVICE_DESCRIPTION + "=My Servlet",
          "sling.servlet.paths="+ "/bin/demotraining/mypath"
          })
          public class MyServlet extends SlingSafeMethodsServlet
          {

          /**
          *
          */
          private static final long serialVersionUID = 3444770797464227100L;
          MyService ms=new MyServiceImpl();

          @Override
          protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException
          {
          response.setHeader("Content-Type","text/html");
          response.getWriter().print("<h1>Sample content using Sling servlet </h1>");
          response.getWriter().print("<h2>My SlingServlet is registered using servlet path</h2>");
          response.getWriter().close();
          }
          }
