    I'm having some trouble with this class. Sometimes the Job is not released and keeps entering the same section. I went to HttpJob class and found the Release Sub is empty. I can even assign the name again after it's released.
    JName = Job.JobName
    JName = Job.JobName
    That code doesn't trigger any error.

    It is not related. It is empty as it is not required in B4i. It is kept for API compatibility with B4A/B4J.

    Where should I copy the httpjob.bas and httpUtils2Service.bas file so it is shared by all projects?

    Do I have to copy this file into every project that uses httpUtils2?

    When I tried to add them into the project it said these two files exit, so I didn't added them

    I am getting a red variable for

    dim jobLogin as httpjob

    I have selected the ihttp library

    the error message is "you are missing a library reference"

    I need to httpjob.bas and httpUtils2Service.bas as modules.

    I created a folder call "shared modules" and copied httpjob.bas and httputils2service.bas into it.

    I changed tools->configure paths->Shared Modules to point to the directory

    I am still getting the library reference error

    I added httpjob.bas and httputils2service.bas as existing modules from the shared module directory
    I can see the modules in the modules tab, (this time there was not a request to override)
    The code compiled.

    Hi Erel, I think there is a bug in iHttputils, concerning :

    Explication, I've create an entry point in a code module:
    Sub InvokeWS(cUrl As String, WsName As String, Jobname As String, ParamValue() As WSParam, DoneAct As String,timeout As Int, message As String  )
    Dim jobtest As HttpJob
    Dim endPoint As String
    Dim requestSoapXML As String
    Dim i As Int

        endPoint = cUrl

        requestSoapXML = _
    "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>" & _
    "<soap:Body>" & _
    "<" & WsName & " xmlns='http://patrick.imbault.org/'>" & CRLF
    For i = 0 To ParamValue.Length -1
                requestSoapXML = requestSoapXML & 
    "<" & ParamValue(i).ParamName & ">" & ParamValue(i).ParamValue & "</" & ParamValue(i).ParamName & ">" & CRLF
            requestSoapXML = requestSoapXML & 
    "</" & WsName & ">" & _
    "</soap:Body>" & _

    Log(requestSoapXML )

        jobtest.PostString ( endPoint, requestSoapXML)
    "SOAPAction""http://patrick.imbault.org/"  & WsName)
    "Content-Type""text/xml; charset=utf-8")
        jobtest.GetRequest.timeout = timeout

    End Sub
    When I call InvokeWS from another code module:

    import code module
    Sub BookJob(cJob As String,cBook As String)
    Dim  UserWs(4As WSParam

    0).ParamName ="username"
    0).ParamValue =Main.SmileLogon.userid
    1).ParamName ="deviceid"
    1).ParamValue =Main.SmileLogon.deviceid
    2).ParamName ="jobid"
    2).ParamValue =cJob
    3).ParamName ="status"
    3).ParamValue = cBook

    "bookjob",UserWs,"import",20000,"Fetching and Booking Job " & cJob & " ...")

    End Sub

    Sub JobDone (job1 As HttpJob)
    Dim sRet As String

    If job1.JobName = "checkjobs" Then
            sRet = tools.GetWsresult(job1,Main.WS_get_pending_jobs,
    If sRet.Length>0 AND sRet <> "-1" Then
    End If
    Else If job1.JobName="bookjob" Then
            sRet = tools.GetWsresult(job1,Main.WS_get_book_job,
    If sRet.Length>0 AND sRet <> "-1" Then
    End If
    End If
    End Sub
    Complete Sub of HttpJob should call JobDone in the import code module
    'Called by the service when job completes
    Public Sub Complete (res1 As HttpResponse)
        res = res1
    CallSub2(target, "JobDone", Me)
    End Sub
    In spite of calling JobDone in the import code module (in that case), it fires an error in the CallSub2 which doesn't find apparently the import code module,

    I had to modify it like this, which in not very good:

    'Called by the service when job completes
    Public Sub Complete (res1 As HttpResponse)
        res = res1
    If target="setup" Then
    CallSub2(setup,"JobDone", Me)
    Else If target="import" Then
    CallSub2(import,"JobDone", Me)
    End If

    'bug here
        'CallSub2(target, "JobDone", Me)
    End Sub
    Many thanks

    The TargetModule parameter should be an object, not a string. You should pass Me instead of "import" and change the type from String to Object.

    V2.10 was uploaded to the first post. It adds support for multipart POST requests.

    For example:
    Dim Job As HttpJob
    "job", Me)
    Dim fd As MultipartFileData
    fd.Dir = 
    fd.FileName = 
    fd.KeyName = 
    fd.ContentType = 
    "", CreateMap("Key1""Value1""Key2""Value2"), Array(fd))

    Hi Erel,

    When posting the string, is there a limit to the size of the string? I get an error when trying to upload a ~300K jpg file. I'm encoding the bytes to 64 bits. If I post a small file 1 or 2k it works fine. Problem when I try to view the string in the log file is the post string gets truncated so I cannot see the entire sent http post.

    I used the equivalant version of this library in my Android project and that works ok with jpgs. I'm now converting my app to iOS but stuck on this final bit.

    OkHttp is a B4A library, not a B4i library. This class depends on iHttp library.

    No. It is a B4i class. However you can copy the sub to B4A HttpJob and it will work.

    I'm a newbie. Sorry for the silly question.
    How can I install the library ?
    I don't find .xml .h or similar files, so I can simply put the files unzipped in

    C:\Program Files (x86)\Anywhere Software\B4i\Libraries

    Thanks in advance
