Hi, I am programming a request to a webservice several times in a loop.
The program gave me this error java.io.FileNotFoundException: C:\Users\GRUPOV~1\AppData\Local\Temp\2 (denied). I am using a system administrator account. I am Glad if someone have a insight about this issue. I am attaching the code (It runs when you click directly to it). I am running in a windows server 2016 with administrator rights and running it from the windows task scheduler.

This Issue is very similar to https://www.b4x.com/android/forum/threads/posible-bug-in-b4j-with-poststring.83965

Best Regards

Call a Webservices several times:
Private Sub Button1_Click
    Dim data As String
    Dim data_list As List
    Dim lineas_registro As List
    Dim requestSoapXML As String
    data_list =  File.ReadList(File.DirApp, "data.csv")
    File.WriteList(File.DirApp, "existencia_inventario.csv", lineas_registro)
    Log("Process Started")
    For i = 0 To 10 ' data_list.Size -1
        Dim j As HttpJob
        Dim material_numero As String
        Dim item_list As List
        j.Initialize("", Me)
        j.Username = "myuser"
        j.Password = "mypassword"
        item_list = Regex.Split(",",data)
        material_numero = item_list.Get(0)
        requestSoapXML =  File.ReadString(File.DirApp, "request.xml")
        requestSoapXML = requestSoapXML.Replace("$MATERIAL$",material_numero)
        requestSoapXML = requestSoapXML.Replace("$CENTRO$","2002")
        j.PostString ("http://myipaddress.com:8102/sap/bc/srt/rfc/sap/zdsd_mm_existencia_preventa/300/zdsd_mm_existencia_preventa/zdsd_mm_existencia_preventa", requestSoapXML)
        Wait For (j) JobDone(j As HttpJob)
        If j.Success Then
        End If
    Log("Process Finished")
End Sub

Hi Erel, Good News!!!,
The program message was
java.io.FileNotFoundException: C:\Users\GRUPOV~1\AppData\Local\Temp\2 (Access Denied) ,

As I said, this is a windows server 2012 machine , with serveral users, so i tried with other users, however, the program break at 15th iteration (with other user break at second iteration), so I Just Find Offending directory "\2" and renamed it to "\2x" and everything works like a charm. Maybe it is related to autorization schema in windows?. I also read that because I am running a .bat file I need to authorize the cmd command?. But renaming the directory work very fine for me. If someone else have a issue like this, it will be good to add comments to this tread.

Best Regards Erel and have a Good Day

Came across this issue. To fix multiple temp folders for user sessions, do this

Using Group Policies (best practice)​

  1. Open Group Policy.
  2. In Computer Configuration, Administrative Templates, Windows Components, Terminal Services, Temporary folders, double-click the Do not use temp folders per session setting.
  3. To disable the creation of a separate temporary folder for each terminal server session, click Enabled. To enable the creation of a separate temporary folder for each terminal server session, click Disabled.
  4. Click OK.
