MAF: Using rest with JSON

Hi all

I use jdev 12.1.3

While practicing the CRG, I am facing a problem with the help of rest with JSON response.

I followed this: https://blogs.oracle.com/adf/entry/simple_get_operation_with_json

A slight difference is that I already have a Restful services with JSON response I have hace created in Oracle Apex.

Following the example, I followed the steps but when I open the application in the Android emulator after deployment, I don't get all the lines, I dropped the data as MAF List View control.

I don't get all the lines and I am showing 0 in the first row.

Please let me know what could be the problem.

Kind regards

See your json output you can't edit it directly to the employee object.

First you must get the json object, then json for the elements array, then one by one, you must create the Employee object.

In addition, you see 0 because for a PGE no integer, the default value is 0 because the data are not filled the json output.

Try the code below and your question should get solved:

answer = restServiceAdapter.send("");

JSONObject jsonObj = new JSONObject (response);

JSONArray empList = (JSONArray) jsonObj.get ('items');

int size = empList.length ();

ArrayList empArray = new ArrayList();

for (int i = 0; i)

try {}

Employee emp = new Employee();

JSONObject result = empList.getJSONObject (i);

String empno = (String) result.get ("empno");

Ename string = (String) result.get ("ename");

emp.setEmpno (Integer.parseString (empno));

emp.setEname (ename);

empArray.add (emp);

} catch (System.Exception e)

{}

Employee [] e = (Employee []) empArray.toArray (New Employee [empArray.size ()]);

e return;

Your method signature must be:

public employee [] fetchEmpDetails()

With the signature above you return an employee table which can be used for a list view.

Let me know if it helps.

Kind regards

MAF and REST

Does anyone know the requirements and limits for the RESTServiceAdapter?
I spent the last day or so to study different options and seem to have reduced in the absence of Content-Length in the response, or maybe connection: close
For example, a REST service that works returns the following raw http response
HTTP/1.1 200 OK
Access-Control-Allow-Origin: *.
Content-Type: application/json
Date: Tuesday, July 22, 2014 10:48:27 GMT
Content-Length: 225
{'ip': '122.109.131.63', 'country_code': "to THE", "country_name": "Australia", "region_code": "05", "region_name": 'South Australia', 'city': 'Adelaide', 'postal code': latitude '',' ':-34.0287, "longitude": 138.0986, ' metro_code ': '',' area_code' ":" "}
Conversely, a REST service that does not work will return the following raw http response
HTTP/1.1 200 OK
Date: Tuesday, July 22, 2014 10:56:02 GMT
Server:
Connection: close
Host: 192.168.0.4:8080
Content-Type: application/json
{'ip': '122.109.131.63', 'country_code': "to THE", "country_name": "Australia", "region_code": "05", "region_name": 'South Australia', 'city': 'Adelaide', 'postal code': latitude '',' ':-34.0287, "longitude": 138.0986, ' metro_code ': '',' area_code' ":" "}
The code I use is this and will display the string correctly for the first sample, but is empty in the second sample.
RestServiceAdapter restServiceAdapter = Model.createRestServiceAdapter ();
Claire each previously defined properties of the request, if any
restServiceAdapter.clearRequestProperties ();

Set the login name
restServiceAdapter.setConnectionName ("GeoIPOAG");

Specify the type of request
restServiceAdapter.setRequestType (RestServiceAdapter.REQUEST_TYPE_GET);    MESSAGE switching makes no difference, get the same results
Specify the number of attempts
restServiceAdapter.setRetryLimit (0);
ADDED to this to see that she had no effect - if not
restServiceAdapter.addRequestProperty("Connection","Keep-Alive");
restServiceAdapter.addRequestProperty ("Content-Type", "application/json");         Define what is recommended in the guide of dev MAF but has no effect
restServiceAdapter.addRequestProperty ("Accept", "application/json");                Define what is recommended in the guide of dev MAF but has no effect
Set the URI which is defined after the end point in the connections.xml.
The application's endpoint + defined URI
restServiceAdapter.setRequestURI("/json/122.109.131.63");
Run the SEND and RECEIVE operation
try {}
System.out.println ("\nInvoking Service REST on GET and the details are" + restServiceAdapter.getRequestURI ());
For a GET request, there is no payload
String answer = (restServiceAdapter.send(""));
System.out.println("\n**********************************************************************************************");
System.out.println ("\nResponse GET album was" + response);
System.out.println("\n**********************************************************************************************");
} catch (Exception e) {}
e.printStackTrace ();
}

Add this in case someone has this problem - the MAF for REST of treatment seems to require Content-Length. Without it, it will not process the answer - that is, the answer is «»

It is a bit of a pain if you have a REST service on the API Oracle Gateway what not will BE NOT Content-Length of back (except if you call another server as part of your policy).

I can't open a backup file of favorites with json extension

I opened the LIBRARY folder in TOOLS, and click BACKUP so that I can get a copy of my favorites to transfer to another laptop.

I saved the file on the DESKTOP. It has an extension of json. Cannot open it. How can I open it. My registry is corrupt? Thank you, cp

The use of a JSON backup is to restore the file through the bookmarks manager in a Firefox profile, which will replace all current bookmarks with those of this JSON backup.

A JSON backup is a text file to the format of the object and is not very readable.

If you want a readable backup then export the Favorites to an HTML file.

Why do you want to open this file?

If you have any question regarding:
- APEX_JSON then - Oracle Application Express (APEX)
- If response JSON and RESTful Services and then - ADR, SODA & JSON in the database
- If JSON in Oracle Database 12 c associated with then - SQL

CS6 Error with JSON

Updated one of my projects to CS6 and now get the error...
Line 188 1061: call to a possibly undefined method decode a reference of static type Class.
CODE:
import com.adobe.serialization.json.JSON;
Si ( » « ! is scormSuspendString) scormSuspend is JSON.decode (scormSuspendString);
This also occurs with the JSON.encode.
Due to differences in the CS6 and CS5.5, could this be another problem?
Thank you

instead of decode/encode, use parse/stringify.

you are publishing for fp 11 + and use the native JSON class actionscript, not mike class room.

Need help with JSON.decode

I get a query response JSON with about 4 deep layers of value of nested objects I need to pierce the. The JSON.decode examples that I find online are very simple and use it and the old syntax which is taken in charge in Flex 4.5.
I was hoping that someone here could give me a tip or two to extract the values of 'html_instructions' of a JSON result like this:
{
"status": "OK."
"routes": [{}
'Summary': ' US-97 S and S I-5.
"legs": [{}
'steps': [{}
"travel_mode": "En ROUTE."

Thanks a lot, a lot in advance!

Hello

As I'm not sure of what api that you use to decode json: once convert you the object info you are looking for is available as:

JSON.routes [0] .legs [0]. Steps [0] .html_instructions

or:

JSON.routes [N] .legs [N]. Steps [N] .html_instructions

Where N is the length of the data "json" and the table is loaded data object, the more

10.6.8 using. With Safari I can view the Apple start page. OK, using Firefox. What happens in the last 24 hours. How can I solve this?

You can solve it using only not the OS X version 10.6, Apple Safari here on out!

Over the years, there were no updating security for what be for OS X 10.6.8 Snow Leopard!

This version of Safari is obsolete and has not been safe to use for many years.

There is one more, last recommended Mozilla Firefox web browser update complete (worms) 48.0.0 that is always available, and probably will be more safe to use until the end of the year.

https://www.Mozilla.org/en-us/Firefox/desktop/

Mozilla is complete, at the end of the present in August, full support for Firefox on OS X 10.6 - 10, 8.

OR

Guaranteed ONLY (not more new web browser feature) support for an earlier version of th is permanent to Mozilla Firefox, web browser (worms. 45.0.0) through their program of Firefox ESR, (that you CAN download, install and use) which will continue to receive the support of a security update to Firefox until next April 2017 for OS X 10.6-10, 8.

You can use these versions of the ESR. Ignore the notes support educational/business.

How can I use tor with firefox?

I found this Tor project recommends do not to use the customer of vidalia. Also, I found that the torbutton add-on has been removed and foxyproxy tor Wizard does not work.
Is it possible to use tor with one other than its built-in firefox browser?

I found that the Tor changed its default port 9050 to 9150 so you can create a proxy setting to help foxy proxy tor Wizard and change its port to 9150.
You can also manually configure the Firefox proxy settings to use localhost on port 9150.

Using Sansung S3, not yet possible to share all the tabs opened (using NFC) with another phone NFC. But only the a main tab, I'm currently browsing is possible.

Sansung S3 using, Android 4.1.2 Firefox 24.0; not yet possible to share all the tabs opened (using NFC) with another phone NFC. But only the a main tab, I'm currently browsing is possible to share. It is the function of current NFC function of Firefox?
If so, when will it feature to share all the tabs?
Thank you.

I don't know if we implement this. Sharing of all the tabs you have open have many security and privacy issues. Someone forget that they had a tab open, they didn't want to share or miss-clicks on the sharing of all the option.

We are looking for ways to better share tabs with devices that are located nearby. Especially if they are on the same WiFi network.
