Hello, in this video I will show you how you can call the rest web service in the ADF application. I will show you how you can call your custom method and there's a built in method using programmatic way because I like to do it in programmatically. So that you could we will be able to call this web service at any Java program you have. So, here I create empty if application core rest application. In this cold rest application, I just create one class. This class has two methods, one to invoke, get wrist web surface and one to invoke ill posed wrist with surface this is a generic function so that you will be able to call it at anywhere in your PDF application.
So let's explain the get wrist function. This get wrist function will receive the rest URL, the URL of your web surface and the content type. Here I will create a URL for this web surface and create a connection. Here I will sit method which is a good method because it's a good method and I will say it's a content type which you will see this symbol and if the status is okay, here, I will build the output to make it symbol here string. Call it final output. Okay, so we'll be more readable for you.
Okay, so once you invokes a get method of course, it must return loads of JSON format line by line. So, here I will a will read line by line and fail the final outputs and I will return the final output for the post web surface, you will send the URL and the content and you will both to the input of this web surface. So, it will be the same, but the request method will be post and here I will sit since the input which you will send and I will return the output of this web service. So, let's try to run it locally here is the main method. So, here you will generate to system out print line I will put into line one will call the JIT missile is a good misheard one will cause a postman So, in Zakat method I sent the URL of the method and I will add even the barometer limited What do we need to return 20 departments and this is the content type same in the post, I will send the URL of the web service seem like we did it here and this is the input and this is the content type.
So, I take the content type here and I take the input to be here. So at least now try to run it here just locally here. So you will find it is invoked correctly is the web surface. the get method will return items department number and all department for 20 departments as opposed to Mrs. Return the finance as a department. So if even in the post missile sits a barometer Instead of 100 to be 10 so, the workmen name will be administration. So, now, we able to call the web surface programmatically and to get output.
But I need to display this output in EDF application by somehow is a table for example, if we need to to displays a get information from the get result from the wrist surface in EDF table okay you able to call it in Java and it written something like this what how I can borrow this information as a Java object to that I will be able to call it so I will use Jackson library Jackson library is you can use it to map the JSON format like this to others. Java plus object and you can display this object in your ADF application as a table. So, this video, I will show you how you can parse or convert the output of the get method to Java objects Java class and how you can display the shell of a class to the ADF beach. So see you Nick activity
