Cannot Access the Servlet

[Punitha77]

I have tried to Launch the workflow through code  and got the below error

Please find below the below code

package com.geeks.demo.core.servlets;

import com.adobe.granite.workflow.WorkflowSession;
import com.adobe.granite.workflow.exec.WorkflowData;
import com.adobe.granite.workflow.model.WorkflowModel;
import org.apache.commons.lang3.StringUtils;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.servlets.SlingSafeMethodsServlet;
import org.apache.sling.servlets.annotations.SlingServletPaths;
import org.apache.sling.servlets.annotations.SlingServletResourceTypes;
import org.osgi.service.component.annotations.Component;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.servlet.Servlet;
import javax.servlet.ServletException;
import java.io.IOException;

@Component(service = Servlet.class)
@SlingServletPaths(
        value={"/bin/executeworkflow","/geeksdemo/executeworkflow"}
)

public class ExecuteWorkflow extends SlingSafeMethodsServlet {
    private static final Logger LOG  = LoggerFactory.getLogger(ExecuteWorkflow.class);

    @Override
    protected void doGet(final SlingHttpServletRequest req, SlingHttpServletResponse res) throws ServletException, IOException{
        String status ="Workflow Executing";
        final ResourceResolver resourceResolver = req.getResourceResolver();

        String payload=req.getRequestParameter("page").getString();
        try {
            if (StringUtils.isNotBlank(payload)) {
                WorkflowSession workflowSession = resourceResolver.adaptTo(WorkflowSession.class);

                WorkflowModel workflowModel = workflowSession.getModel("/var/workflow/models/practice-creation-version-");
                WorkflowData workflowData = workflowSession.newWorkflowData("JCR_PATH", payload);
                workflowSession.startWorkflow(workflowModel, workflowData);
            }
        } catch(Exception e){
                LOG.info("/n Error in Workflow{}", e.getMessage());
            }
        }



}


Steps Tried 
1. Added /geeksdemo/ in the execution path of Apache Sling servlet/ Script Resolver and Error Handler
2. Added  -/content/geeksdemo/um in Apache Sling Authentication Service

Please share your suggestion

Thanks,
Punitha

@Punitha77 Could you please check servlet url in servlet resolver and see how its resolving?

http://localhost:4502/system/console/servletresolver

[Punitha77]

 

[Saravanan_Dharmaraj]

@Punitha77 Open /system/console/configMgr and search for "Apache Sling Servlet/Script Resolver and Error Handler" and add "/geeks/" under execution path and test it. 

Also verify if the /bin/executeworkflow path works in servlet resolver

@Saravanan_Dharmaraj  I have tried to add to /geeksdemo/ and even /geeks/ as you said to "Apache Sling Servlet/Script Resolver and Error Handler"

Hi, 

Did you check if the bundle is activated? And then if the servlet is registered and exported? The code looks ok, so double-check that the code is installed correctly. You could try to remove all the bundle and reinstall it again, to make sure the latest code is being deployed.

Hope this helps

@diksha_mishra I tried both it didn't work for me. Still trying to figure out the issue

[EstebanBustamante]

If you go to your bundle, can you check if your servlet is correctly exported?, can you provide a sc?
