resty gwt - How can I create synchronous calls to rest via javascript using GWT? -

-

I'm calling my GWT client for the web service being hosted on a different server of Javascript which requires the answer And sung on the UI I used to do it comfortably through living organisms but I am unable to capture the response when the JavaScript method is called from HTML which in turn invokes the rest call. Besides, I want to make sure that if I bring two calls from Javascript after the second call (which calls each other) then the second call is only made when the call is completed first. Is there any way to achieve that?

I think there are 2 different problems in your question: / P>

A) that Unable to capture the response

B) Create a sequence of calls

for A) Should you give us more information, code snippets, is it related to your problem? B) These are my suggestions.

If you are using 2 asynchronous calls then there is no way to guarantee that the second will return before the second one. Still you can get some sort of synchronization differently.

I see 2 options

1) Wait for the first call to launch the second call. This means by sending the second call on the onsoot of the first call (and possibly even if your argument is unsuccessful).

This option is not optimal in terms of performance because you may have to wait before the unnecessary time, the second request is sending, depending on if it comes to the reply of the first request to send you the second information. Needs some information.

2) Send the call independently, then save the boolean (OK1 and oak 2) within the onuscut method of each call. Call the same method within 2 ofSuccess methods: afterBothSuccess ()

Check the value of 1 and 2 right inside this method 

  If (Ok1 & amp; oak 2) // Here you are guaranteed that both of your calls are returned successfully

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
