I have been requested to create a function for a web application where on the click of a button from Application A (Ruby on Rails Application) I generate a file with information that can be interpreted by Application B (Jboss/Maven Web App).
From web app A a new page opens up and shows a calculated result in web app B.
The calculated information from web app A is currently a json object to be sent (gson api) and the calculation performed on web app B is done in javascript.
So as of now I am using a form to send the data and open a new page via a GET request but I have concerns regarding the limitations of the GET request and how I should be able to retrieve the information from web app B's javascript on initiation.
Here is what I am currently doing.
Web App A
The json object
{ places: [ { latitude: 45.1, longitude: 15.2, city: 'Croatia' },
{ latitude: 30.254528,
longitude: -97.84536,
city: 'Regents School of Austin, 3230 Travis Country Circle, Austin, TX 78735, USA' },
{ latitude: 46.22764, longitude: 2.213749, city: 'France' },scores:[ 0,
0,
0,
0.0055555557,
0,
0,
0 ],transmissions: [ [ 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0 ],
[ 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0 ],
[ 0, 1, 0, 0, 1, 3, 0, 0, 0, 0, 0, 0, 0, 2, 1, 1, 1 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ] ] }'"
The form code created by JQuery:
$('body').append($('<form/>').attr({
'action': 'http://0.0.0.0:8080/webAppB',
'method': 'get',
'target': '_blank',
'id': 'centrality'
}).append($('<input/>').attr({
'type': 'application/json',
'name': 'jsRequest',
'value': JSON.stringify(arguments)
}))).find('#centrality').submit();
Web App B (javascript)
Parsing the GET data with
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
then perform the action on start.
The information I am passing to web app B will vary in size. It is very possible to go over 2 kb with some of these json requests.
the current get parameter looks like this
jsRequest="{\"places\"%3A[{\"latitude\"%3A45.1%2C\"longitude\"%3A15.2%2C\"city\"%3A\"Croatia\"}%2C{\"latitude\"%3A30.254528%2C\"longitude\"%3A-97.84536%2C\"city\"%3A\"Regents+School+of+Austin%2C+3230+Travis+Country+Circle%2C+Austin%2C+TX+78735%2C+USA\"}%2C{\"latitude\"%3A46.22764%2C\"longitude\"%3A2.213749%2C\"city\"%3A\"France\"}%2C{\"latitude\"%3A53.41291%2C\"longitude\"%3A-8.24389%2C\"city\"%3A\"Ireland\"}%2C{\"latitude\"%3A37.09024%2C\"longitude\"%3A-95.71289%2C\"city\"%3A\"United+States\"}%2C{\"latitude\"%3A55.37805%2C\"longitude\"%3A-3.435973%2C\"city\"%3A\"United+Kingdom\"}%2C{\"latitude\"%3A-38.416096%2C\"longitude\"%3A-63.616673%2C\"city\"%3A\"Argentina\"}%2C{\"latitude\"%3A23.424076%2C\"longitude\"%3A53.847816%2C\"city\"%3A\"United+Arab+Emirates\"}%2C{\"latitude\"%3A56.130367%2C\"longitude\"%3A-106.34677%2C\"city\"%3A\"Canada\"}%2C{\"latitude\"%3A49.817493%2C\"longitude\"%3A15.472962%2C\"city\"%3A\"Czech+Republic\"}%2C{\"latitude\"%3A12.879721%2C\"longitude\"%3A121.77402%2C\"city\"%3A\"Philippines\"}%2C{\"latitude\"%3A41.87194%2C\"longitude\"%3A12.56738%2C\"city\"%3A\"Italy\"}%2C{\"latitude\"%3A51.16569%2C\"longitude\"%3A10.451526%2C\"city\"%3A\"Germany\"}%2C{\"latitude\"%3A60.128162%2C\"longitude\"%3A18.643501%2C\"city\"%3A\"Sweden\"}%2C{\"latitude\"%3A52.132633%2C\"longitude\"%3A5.291266%2C\"city\"%3A\"The+Netherlands\"}%2C{\"latitude\"%3A46.818188%2C\"longitude\"%3A8.227512%2C\"city\"%3A\"Switzerland\"}%2C{\"latitude\"%3A50.503887%2C\"longitude\"%3A4.469936%2C\"city\"%3A\"Belgium\"}]%2C\"scores\"%3A[0%2C0%2C0.05347222%2C0%2C0.0125%2C0.34513888%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0.0055555557%2C0%2C0%2C0]%2C\"transmissions\"%3A[[0%2C1%2C1%2C0%2C0%2C1%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C1%2C0%2C0%2C0]%2C[0%2C0%2C1%2C0%2C0%2C1%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C1%2C0%2C0%2C0]%2C[0%2C1%2C0%2C0%2C1%2C3%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C2%2C1%2C1%2C1]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[1%2C0%2C1%2C0%2C0%2C2%2C0%2C0%2C1%2C0%2C0%2C1%2C1%2C0%2C0%2C0%2C0]%2C[1%2C1%2C3%2C1%2C3%2C0%2C2%2C1%2C1%2C1%2C1%2C1%2C1%2C2%2C1%2C1%2C0]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C1%2C0%2C2%2C1%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C0%2C0%2C0%2C1%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C1%2C2%2C0%2C0%2C2%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C1%2C1%2C0]%2C[0%2C0%2C1%2C0%2C0%2C1%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]%2C[0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0]]}"
As of now that GET parser does not function and even if I write/find a parser,this process may not get the job done for all data sets.
I have tried to use a post from a form, however it gives me the following error:
"NetworkError: 415 Unsupported Media Type
This only happens from the form though and I had assumed it was due to forms auto use of application/x-www-form-urlencoded data type.
the code on web app b runs fine if I make a straight ajax post, but that will not show the web page with the information I desire. Just a response json that I am further trying to send and run in client side javascript.
So Im wondering if I am taking the wrong approach?
