Are you trying to create the client using wsimport and deploy the same on server?

Thanks a lot Martin

Hi Moderator i need to edit my post
https://coderanch.com/t/620233/Web-Services/java/Expression-based-Json-Query-Engine

in the last part of the post i need to change the line
List<String> names = JsonQueryEngine.getExpressionValues(String expression, String propertySeperator, JSONObject jsonObject);
With
List<String> names = JsonQueryEngine.getExpressionValues("Persons.name", ":", JSONObject jsonObject);

Can you please help?

Hi Ranchers,

Here is a small utility to query the JsonObject for a particular property. It may be helpful to some of you.

import java.util.ArrayList; import java.util.List; import org.json.JSONArray; import org.json.JSONObject; public class JsonQueryEngine { public static List<String> getExpressionValues(String expression, String propertySeperator, JSONObject jsonObject) throws Exception{ String[] nodesList = expression.split(propertySeperator);//Splitting each property in expression List<String> expressionValues = new ArrayList<String>(); List<JSONObject> jsonObjects = new ArrayList<JSONObject>(); //Temporary Objects for swapping (Won't consume much memory as the values are pointers) List<JSONObject> intermediateJsonObjects = new ArrayList<JSONObject>(); jsonObjects.add(jsonObject); //Populating targeted Json for (int i = 0; i < nodesList.length - 1; i++) { for (JSONObject propertyObject : jsonObjects) { intermediateJsonObjects.addAll(getNodeJsonObjects(nodesList[i], propertyObject)); } jsonObjects.clear(); jsonObjects.addAll(intermediateJsonObjects); intermediateJsonObjects.clear(); } //Populating targeted Json Values for (JSONObject propertyObject : jsonObjects) { expressionValues.add(propertyObject.get(nodesList[nodesList.length - 1]).toString()); } return expressionValues; } private static List<JSONObject> getNodeJsonObjects(String node, JSONObject parentObject) throws Exception{ List<JSONObject> nodeJsonObjects = new ArrayList<JSONObject>(); Object object = parentObject.get(node); if(object instanceof JSONObject) nodeJsonObjects.add((JSONObject)object); else{ JSONArray jsonArray = (JSONArray)object; for (int i = 0; i < jsonArray.length(); i++) { nodeJsonObjects.add((JSONObject)jsonArray.get(i)); } } return nodeJsonObjects; } }

It contains a static public method which accepts an expression, property separator and JsonObject.

The expression can be of the form Node1:Node2:Node3, where Node3 is the targetted property and ":" is a property seperator. See Sample.

{ "Persons":[ { "name":"Jack", "age":35, "profession":"Engineer", "gender":"male", "addresses":[ { "addressType":"postal", "addressValue":"No 23 North Edmund, San Jose California" }, { "addressType":"email", "addressValue":"jack@jack.com" }, { "addressType":"home phone", "addressValue":"00000" }, { "addressType":"cell phone", "addressValue":"11111" } ] }, { "name":"Jill", "age":30, "profession":"Singer", "gender":"female", "addresses":[ { "addressType":"postal", "addressValue":"No 23 North Edmund, San Jose California" }, { "addressType":"email", "addressValue":"jill@jill.com" }, { "addressType":"home phone", "addressValue":"00000" }, { "addressType":"cell phone", "addressValue":"22222" } ] } ] }

if you want to query the name property of the above object then you can call the method as
List<String> names = JsonQueryEngine.getExpressionValues("Persons:name", ":", jsonObject);

The output of the method is list of string, i.e if the targeted property is a JsonObject then it will be toString() ed.

Hi,

My query is regarding practical of OCPJWSD. Can you please suggest some link(s) or books for practical?
Currently, I am stuck to following example/situation -
- Environment: Eclipse, Tomcat 7.0, JDK 1.7, Axis2.
- Create a WebService with annotation @WebService, @WebMethod, @SOAPBinding.
Here, I am unable to create a WSDL. I am trying to access a webservice using standalone client and stub.

If you have any input, please comment.

Thanks in advance,
Satyajit Bhosale

http://www.eclipse.org/webtools/community/tutorials/BottomUpAxis2WebService/bu_tutorial.html

Please go through the link. Also there is nothing wrong in using Eclipse for your practice / real development. Atlast thats why its built for. I suggest you to try out contract first approach od web service development for better understanding. Have a look at Apache CXF its really good and widely used.

No i was unable to overcome this. It will help if you pin point the exact location. Didnt find any clue in the code.

thanks Ulf that was it.....

Hi Ranchers,

I have to share some information between two web apps. for that i am trying to use cookies. I have two web apps (App1 and App2) hosted on the same tomcat server. when user navigate to App1 (http://localhost:8080/App1) i set a session cookie, when user navigates to App2 http://localhost:8080/App2) i want that cookie to do some logic (also i want the Vice-Versa). is this possible using cookies? if yes can you please tell me how to implement? if no, any other mechanism to share session related information across webapps?

Yes, exactly that is the problem...... here is my dependency tree, in this it is nowhere mentioned the dependency on hibernate 3.x...... I dont know why my org.springframework.orm.hibernate4.LocalSessionFactoryBean initialize method refering to that......... may be some bug in spring..... will try to post my issue in springsource community......

Thanks Mark

thanks for sharing chris....... looks like a treasure...........

As per my (limited )knowledge of Map-Reduce algorithm, i believe that in a job, reduce tasks will start running only after all the map tasks (also the combiner tasks if there are any) have finished execution. if there is no chance of a reduce task running (correct me if i am wrong ) while there are pending map tasks, why the tasktracker have separate (configurable) slots for map and reduce tasks? i have read that before starting a map task, a task tracker will look for a free map task slot, if it finds any it will allocate that slot to the map task, if there are no free task slots left then it will allocate a slot from reduce task slot . i just want to know why there is a configuration like this in hadoop . is this configuration is per job (make no sense, since reduce tasks cannot start before the completion of all map tasks.... again correct me if i am wrong) or per system (a system with many job...... this make some sense )

SOLVED!!! i was missing a schemapattern attribute in ddltodatabase task. thank peter.
