Greetings, been banging my head against the wall on this one. I'm using jRDC2 with B4J for my android, when I run my SELECT statement it works
SELECT:
Sub get_user (count As Int)
    Dim req As DBRequestManager = CreateRequest
    Dim cmd As DBCommand = CreateCommand("get_one_user", Array(count))
    Wait For (req.ExecuteQuery(cmd, 0, Null)) JobDone(j As HttpJob)
    If j.Success Then
        req.HandleJobAsync(j, "req")
        Wait For (req) req_Result(res As DBResult)
        'work with result
        req.PrintTable(res)
    Else
        Log("ERROR: " & j.ErrorMessage)
    End If
    j.Release
End Sub

But when I try my INSERT
INSERT fails:
Sub add_user(fullname As String)
    Dim cmd As DBCommand = CreateCommand("add_user", Array(fullname))
    Dim j As HttpJob = CreateRequest.ExecuteBatch(Array(cmd), Null)
    Wait For(j) JobDone(j As HttpJob)
    If j.Success Then
        Log("Inserted successfully!")
    End If
    j.Release
End Sub

The error I get in the log is
ResponseError. Reason: Server Error, Response:
<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>
<title>Error 500 org.eclipse.jetty.io.EofException: Closed</title>

(I took out the HTML tags, wasnt sure it would affect the post)

my config.properties SQL commands are
sql.get_one_user = SELECT full_name FROM UserTable WHERE count = ?;
sql.add_user = INSERT INTO UserTable (full_name) VALUES (?);

I'd appreciate any suggestions. Thanks.

Another clue would be the log that is produced by the jRDC2 server. For initial setup, I usually just run jRDC2 from the IDE (often in Debug mode) and then use the log window to see what is going on server side.

I think you mean this log:

Command: query: getusers, took: 256ms, client=192.168.0.11
(MySQLSyntaxErrorException) com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'full_name VALUES ['Kirk']' at line 1
(EofException) org.eclipse.jetty.io.EofException: Closed
Command: , took: 4ms, client=192.168.0.11


I think you may have found the issue. I have missed this community.
I had a field that did not have a default value, I change that to null and it solved the issue.
Thank you Oliver, Aeric and Jose.
