Android Question [SOLVED] JRDC2 and Class

yfleury · Jan 9, 2020

I am noob with Class.

I have huge project and to simplify maintenance I want to put all my code for jrdc2 in class.
I can access to jrdc2 server,

My sub

My sub:

public Sub checkInternetEtServeur As ResumableSub
    Main.rdcLink = "http://192.168.1.149:17178/rdc"
    Dim req As DBRequestManager = CreateRequest
    Dim cmd As DBCommand = CreateCommand("select_test", Array())
    Wait For (req.ExecuteQuery(cmd, 0, Null)) JobDone(j As HttpJob)
    If j.Success Then
        LogColor("Server ok",Colors.Green)
        Return True
    Else
        LogColor("Server no ok",Colors.Red)
        Return False
    End If
End Sub

On jrdc2 server sql.select_test=select Version()
.

but I receive an error:

*** Service (httputils2service) Create ***
** Service (httputils2service) Start **
ResponseError. Reason: java.lang.ClassNotFoundException: yves.fleury.dbserveur$_dbcommand, Response: <html>
<head>

</body>
</html>
Server no ok

How can resolved that?

Maybe more info could be help

In class module:

Sub Class_Globals
    Type DBResult (Tag As Object, Columns As Map, Rows As List)
    Type DBCommand (Name As String, Parameters() As Object)
End Sub

 Sub CreateRequest As DBRequestManager
    Dim req As DBRequestManager
    req.Initialize(Me, Main.rdcLink)
    Return req
End Sub

public Sub CreateCommand(Name As String, Parameters() As Object) As DBCommand
    Dim cmd As DBCommand
    cmd.Initialize
    cmd.Name = Name
    If Parameters <> Null Then cmd.Parameters = Parameters
    Return cmd
End Sub

The type declarations must happen in Main as per https://www.b4x.com/android/forum/t...-rdc-remote-database-connector.61801/#content
