I need to display the title and name of all child and grand child pages from given path in JSON format. Please provide the implementation.
First You have to try something yourself, then you call for help, not the complete solution!anyway there are couple of solution down there.
According to Adobe here you can implement page information in JSON format:
package com.adobe.example;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.ReferenceCardinality;
import org.apache.felix.scr.annotations.Service;
import org.apache.felix.scr.annotations.Reference;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.commons.json.JSONException;
import org.apache.sling.commons.json.JSONObject;
import com.day.cq.wcm.api.Page;
import com.day.cq.wcm.api.PageInfoProvider;
#Component(metatype = false)
#Properties({
#Property(name="service.description", value="Returns the public URL of a resource.")
})
#Service
public class PageUrlInfoProvider implements PageInfoProvider {
#Reference(cardinality = ReferenceCardinality.OPTIONAL_UNARY)
private com.day.cq.commons.Externalizer externalizer;
private String fetchExternalUrl(ResourceResolver rr, String path) {
return externalizer.publishLink(rr, path);
}
public void updatePageInfo(SlingHttpServletRequest request, JSONObject info, Resource resource)
throws JSONException {
Page page = resource.adaptTo(Page.class);
JSONObject urlinfo = new JSONObject();
urlinfo.put("publishURL", fetchExternalUrl(null,page.getPath()));
info.put("URLs",urlinfo);
}
}
Or you may try this Page for solution
Please refer to below link which may be useful:
http://www.nateyolles.com/blog/2015/12/converting-aem-sling-resources-to-json.
Apart from the above solution you also use recursive level to get the data in the JSON format for example /content/we-retail/language-masters/en.{placeholder}.json
replace the placeholder with the level of nodes you want to print and return back the JSON wherever needed.
To know more about the rendering data in different formats,
Refer: https://sling.apache.org/documentation/bundles/rendering-content-default-get-servlets.html

Before marking this as duplicate, just wanted you guys to know I have checked out the question posted here:
What is the difference between #PathParam and #PathVariable
Thing is, if the usage of PathParam and PathVariable are same (only that one is from the JAX-RS API and one is provided by Spring), why is it that using one gives me null and the other gives me the proper value?
I am using Postman to invoke the service as:
http://localhost:8080/topic/2
(I'm very new to SpringBoot)
Using PathParam :
import javax.websocket.server.PathParam;
import org.apache.tomcat.util.json.ParseException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class TopicController {
#Autowired
TopicService topicService;
#RequestMapping(method=RequestMethod.GET,path="/topic/{id}")
public Topic getById(#PathParam("id") long id) throws ParseException {
return topicService.getTopicById(id); //-- here id comes as null (when id is declared as a wrapper type - Long, else it throws an error)
}
}
Using PathVariable:
#RestController
public class TopicController {
#Autowired
TopicService topicService;
#RequestMapping(method=RequestMethod.GET,path="/topic/{id}")
public Topic getById(#PathVariable("id") long id) throws ParseException {
return topicService.getTopicById(id); //-- here id comes as 2
}
}
I think the pathparam in your project is under javax.ws... This one is not what they talked about. It is used in websocket, which means it is not a http annotaiton. JBoss implement pathparam needs additional jars.
I have 2 different test cases which have different URL's.
Common thing between two URL's is the unique ID. I have captured the URL of one test case and split the URL of that test case and stored the ID in a variable. I made that variable a global variable and tried to use it in 2nd test case.
Now, I want to use that ID obtained from 1st test case in 2nd test case.
I got the error below:
**Test Case FAILED because (of) org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'ba0eed2c-cba8-11e8-86a5-02e9072e0d95' with class 'java.lang.String' to class 'internal.GlobalVariable'**
**Code for Test Case A is as follows:**

WebUI.setText(findTestObject('PO_ID_Details_Passport/input_2'), '2025')
// Capture the current URL and split the URL to get the unique ID.
String url = WebUI.getUrl()
String getQueryString = url.split("\\?")[1]
String[] getFields = getQueryString.split("&")
Map<String, String> fieldValueMap = new HashMap<String, String>()
for(String field : getFields) {
fieldValueMap.put(field.split("=")[0], field.split("=")[1])
}
println fieldValueMap.get("JID")
GlobalVariable JourneyID=fieldValueMap.get("JID")
//return JourneyID
Thread.sleep(5000)
WebUI.click(findTestObject('PO_ID_Details_Passport/Upload_File'))
Thread.sleep(3000)
//Sample path. Change it to your saved location of autoIT script
Runtime.getRuntime().exec('ABC')
Thread.sleep(5000)
WebUI.click(findTestObject('PO_ID_Details_Passport/i'))
]
How can I use the value of JourneyID in different test case?
you can use A global variable to store value as shown below.
GlobalVariable.JourneyID=fieldValueMap.get("JID")
But before using this variable, create a Global Variable named 'JourneyID' and pass some static value to it.
Now you can use it in other test cases.
Hope this will help you.
I need to manipulate owl file using the Protege-Owl API. You know, creating classes and properties isn't too difficult.But I don't know how to delete a class or property.If we treat the owl file as a graph, deleting an class means deleting an node and its direct edge.For exemple:
<owl:unionOf rdf:parseType="Collection">
<rdf:Description rdf:about="&data;DataBundle"/>
<rdf:Description rdf:about="&data;DataItem"/>
</owl:unionOf>
if I want to delete the class DataItem,
how should I do it using Protege-OWL API? Does RDFResource.delete()can achieve this? I have tried it,but I can't achieve this,maybe there is something wrong.
what will I get after I delete the DataItem?
If DataItem is the domain of an property, what will I get after I delete it?
I hope to get your answer.
Edit: the Protege OWL API is the api described here, not the OWL API described here.
#Joshua Taylor,Thank you for your answer!I'm a new user and I make a mistake for posting this problem twice.Sorry for that.I make some mistakes in my code at first and today I tried to fix it.The following codes can delete a class or property.
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import java.net.URI;
import edu.stanford.smi.protegex.owl.ProtegeOWL;
import edu.stanford.smi.protegex.owl.jena.JenaOWLModel;
import edu.stanford.smi.protegex.owl.model.RDFResource;
public class DeleteClass {
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
//get model from an owl file
String filePath = "D:\\ss.owl";
FileInputStream inFile= new FileInputStream(filePath);
Reader in = new InputStreamReader(inFile,"UTF-8");
JenaOWLModel jenaOwlModel = ProtegeOWL.createJenaOWLModelFromReader(in);
//get an class from the model
RDFResource oneClass=jenaOwlModel.getRDFResource("Person");
RDFResource oneDataProperty=jenaOwlModel.getRDFResource("age");
//delete the resource
oneClass.delete();
oneDataProperty.delete();
//save the model to another owl file
URI file=URI.create("file:///D:/ssChange.owl");
System.out.println(file);
jenaOwlModel.save(file);
//System.out.println(oneClass);
}
}
I implemented workflows, but it would be nice to know if there are hooks provided by the client library which allow to hook in. When a workflow was triggered and finished, a CQ.Notification should be displayed. Or do i need to implement a polling library by myself?
As far as I know, there is no built-in CQ area to see when something is done, aside from looking here:
http://yoursite.com:port/libs/cq/workflow/content/console.html
Once there, you can go to the 'Instances' tab and see what's happening.
In one application that I worked on, we ended up writing our own method that sends notifications to us based on one of our workflows (our workflow ties into it - from the workflow models area, you can set your process to be a servlet that you've put into CQ). Here is the main piece of code from our servlet that catches the process being active, and then calls our methods to email us based on what it finds:
import com.day.cq.workflow.WorkflowException;
import com.day.cq.workflow.WorkflowSession;
import com.day.cq.workflow.exec.WorkItem;
import com.day.cq.workflow.exec.WorkflowData;
import com.day.cq.workflow.exec.WorkflowProcess;
import com.day.cq.workflow.metadata.MetaDataMap;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.Service;
import org.osgi.framework.Constants;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import javax.jcr.Node;
import javax.jcr.RepositoryException;
import java.util.Arrays;
public class YourServletName implements WorkflowProcess {
#Override
public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap args) throws WorkflowException {
session = workflowSession.getSession();
final WorkflowData data = workItem.getWorkflowData();
String type = data.getPayloadType();
String[] argStrings = args.get("PROCESS_ARGS", ARG_UPDATED).split(",");
String reason = argStrings[0];
String baseUrl = argStrings[1];
try {
if (type.equals(TYPE_JCR_PATH) && data.getPayload() != null) {
String resourcePath = data.getPayload().toString();
logger.info("Send Notification that {} has been {}.", resourcePath, reason.toLowerCase());
if (resourcePath != null && !resourcePath.isEmpty()) {
ResourceInfo resourceInfo = new ResourceInfo(resourcePath, baseUrl);
sendEmail(resourceInfo, reason);
}
}
} catch (EmailException ex) {
logger.warn("Failed to send Email");
throw new WorkflowException(ex);
} catch (MailingException ex) {
logger.warn("Failed to send Email");
throw new WorkflowException(ex);
}
}
}
You can find more info in the documentation for Extending Workflow Functionality.
Look at the first code block on that page, and that will give you the best idea of how you can implement a custom workflow handler.
EDIT
If you want to see it on the front-end, you could do an AJAX call to get the JSON list of currently running workflows - you can hit this url:
http://localhost:4502/etc/workflow/instances.RUNNING.json
Then you could loop through them and see if yours is in there. This isn't very nice though, since they are all just listed by IDs. I would instead suggest using the querybuilder, or again, just doing an AJAX GET. This is one example:
1_group.0_path=/etc/workflow/instances
2_group.0_type=cq:Workflow
0_group.property.2_value=COMPLETED
0_group.property=status
0_group.property.and=true
3_group.property=modelId
3_group.property.2_value=/etc/workflow/models/your-model-name/jcr:content/model
3_group.property.and=true
Then the URL would look something like this:
http://yoursiteurl:port/libs/cq/search/content/querydebug.html?_charset_=UTF-8&query=http%3A%2F%2Fyoursiteurl%3Aport%3F%0D%0A1_group.0_path%3D%2Fetc%2Fworkflow%2Finstances%0D%0A2_group.0_type%3Dcq%3AWorkflow%0D%0A0_group.property.2_value%3DRUNNING%0D%0A0_group.property%3Dstatus%0D%0A0_group.property.and%3Dtrue%0D%0A3_group.property%3DmodelId%0D%0A3_group.property.2_value%3D%2Fetc%2Fworkflow%2Fmodels%2Fyour-model-name%2Fjcr%3Acontent%2Fmodel%0D%0A3_group.property.and%3Dtrue
It's ugly, but it gets you the results you need, and then you can parse them to get further information you need.
I try to get the titles and URLs from a public Picasa album. But I am stuck at the very beginning: I cannot create a new PicasawebService.
My Code:
import java.util.List;
import java.io.File;
import java.net.URL;
import com.google.gdata.client.*;
import com.google.gdata.client.photos.*;
import com.google.gdata.data.*;
import com.google.gdata.data.media.*;
import com.google.gdata.data.photos.*;
import java.util.ArrayList;
public class PicasaManager implements PicasaConnector {
public List<Avatar> getPhotoURLs() throws Exception {
PicasawebService myService = new PicasawebService("HI");
myService.setUserCredentials("foo#gmail.com", "mypassword");
ArrayList<Avatar> rl = new ArrayList<Avatar>();
URL feedUrl = new URL("https://picasaweb.google.com/111420671758947023853/EWA2012");
System.out.println("dddddddddddddddddd");
AlbumFeed feed = myService.getFeed(feedUrl, AlbumFeed.class);
for (PhotoEntry photo : feed.getPhotoEntries()) {
Avatar a1 = new Avatar();
a1.setDescription(photo.getTitle().getPlainText());
a1.setUrl(photo.getMediaThumbnails().get(0).getUrl());
rl.add(a1);
}
return (rl);
}
}
The Error Message:
Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.collect.ImmutableSet.copyOf([Ljava/lang/Object;)Lcom/google/common/collect/ImmutableSet;

test.java is my test class with the public static void main method,
Avatar is a class with two variables: description and url, there are getters and setters for both
in my netbeans IDE line 27 of the PicasaManager.java file is: PicasawebService myService = new PicasawebService("HI");
the implemented interace only defines the getPhotoURLs() method
I have no idea how to solve this problem, i hope somebody here can help me.
Have you included gdata-core-1.0.jar and guava-12.0.jar? Good luck on the rest of Web Engineering UE4 ;-)
