B4J Question Deployment Tutorial

[raphipps2002]

Is there one for this? So the app is ready...how do i publish it so that users can download it and also be advised of Auto updates?

The complete app is packed as a single jar file. You can distribute this jar.

There are also programs that will take a Java jar file and will convert it to a Windows exe file (allowing you to change the icon).

Another option is to use an installer that deploys the JAR file as is, with no wrapper, and creates shortcuts that have an alternative icon.

This gets around the problem inherent in all of the EXE-wrappers I've seen, which extract the JAR into a temporary directory and either delete after run or just leave it sitting there taking up space.

Ok..thanks...I suppose I could deploy it with vb.net; a simple vb.net app the download the jar file..or is something possible in B4J

like this in vb.net

 Sub DownLoadFileFromServer()

        Dim client As WebClient = New WebClient

        client.Credentials = New Net.NetworkCredential("username", "password")

        Try

            AddHandler client.DownloadProgressChanged, AddressOf client_ProgressChanged
            AddHandler client.DownloadFileCompleted, AddressOf client_DownloadCompleted

        Catch ex As Exception

            MsgBox(ex.Message)


        End Try

        Try

            Dim DownlaodFolder As String = FileName

            'client.DownloadFileAsync(New Uri("ftp://ftp.xxxxxxxxxxxxxxxxxxxx/DB/xxx.jar"), "c:\cashbook\DB")

            client.DownloadFileAsync(New Uri("ftp://ftp.xxxxxxxxxxxxxxxxxxxxDB/xxx.jar"), DownlaodFolder)


        Catch ex As Exception

            MsgBox("DB Download Error Line 11116  System Data is incomplete.  Please call support " & ex.Message)

        End Try

    End Sub

You can use the jNet library to download the jar and then run it with jShell (or jFX.OpenExternalDocument).
