B4J Question Automating data collecting from web pages with Ajax

[iglrs1]

Hi,

I want to automate some tasks (data colleting) in some webpages. I'm using the webview control and I have some questions:

a) Error com.sun.webkit.network.URLLoader doRun error,
When I login on the webpage I receive in the log the current error:

Waiting for debugger to connect...
Program started.

Looking in the forum I found and added the SetSystemProperty but still same error

SetSystemProperty("deployment.security.TLSv1", "true")
SetSystemProperty("https.protocols", "TLSv1")
MainForm = Form1
MainForm.RootPane.LoadLayout("1") 'Load the layout file.
MainForm.Show
WebView1.LoadUrl("https://www.audaxenergia.com/")

Wait For WebView1_PageFinished(Url As String)

b) In a Webpage with AJAX I need to wait until the Ajax is executed. This is done after pressing a enter in an input field (Pressing the enter is done by code ). The Wait For WebView1_PageFinished(Url As String) is not working. Could someone help me?

Dim js As String = $"e=jQuery.Event('keyup');
                             e.which = 13;
                             e.keyCode = 13;
                             $('input[name="test"]').keypress().trigger(e);"$

joWV.RunMethodJO("getEngine", Null).RunMethod("executeScript", Array As String(js))
Wait For WebView1_PageFinished(Url As String)

I've tried it with:

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("1") 'Load the layout file.
    MainForm.Show
    WebView1.LoadUrl("https://www.audaxenergia.com/")
End Sub

The web page is loaded properly. There is an error about an invalid cookie which is probably a server problem. However the site loads.

I tested it with Java 11.

Thanks Erel. Any idea for the second question?

 

[Erel]

Each thread should focus on a single question or issue. If the SSL issue was resolved then start a new thread for the second one.

OK, thanks
