JDEdwards XMLInterop

Wondering if anybody out there has any success in using the JDEdwards XMLInterop functionality. I've been using it for a while (with a simple PInvoke, will post code later). I'm looking to see if there's a better and/or more robust way.

Thanks.

As promised, here is the code for integrating with JDEdewards using XML. It's a webservice, but could be used as you see fit.

namespace YourNameSpace

{

/// <summary>
/// This webservice allows you to submit JDE XML CallObject requests via a c# webservice
/// </summary>
[WebService(Namespace = "http://WebSite.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class JdeBFService : System.Web.Services.WebService
{
    private string _strServerName;
    private UInt16 _intServerPort;
    private Int16 _intServerTimeout;

    public JdeBFService()
    {
        // Load JDE ServerName, Port, & Connection Timeout from the Web.config file.
        _strServerName = ConfigurationManager.AppSettings["JdeServerName"];
        _intServerPort = Convert.ToUInt16(ConfigurationManager.AppSettings["JdePort"], CultureInfo.InvariantCulture);
        _intServerTimeout = Convert.ToInt16(ConfigurationManager.AppSettings["JdeTimeout"], CultureInfo.InvariantCulture);

    }

    /// <summary>
    /// This webmethod allows you to submit an XML formatted jdeRequest document
    /// that will call any Master Business Function referenced in the XML document
    /// and return a response.
    /// </summary>
    /// <param name="Xml"> The jdeRequest XML document </param>
    [WebMethod]
    public XmlDocument JdeXmlRequest(XmlDocument xmlInput)
    {
        try
        {
            string outputXml = string.Empty;
            outputXml = NativeMethods.JdeXmlRequest(xmlInput, _strServerName, _intServerPort, _intServerTimeout);

            XmlDocument outputXmlDoc = new XmlDocument();
            outputXmlDoc.LoadXml(outputXml);
            return outputXmlDoc;
        }
        catch (Exception ex)
        {
            ErrorReporting.SendEmail(ex);
            throw;
        }
    }
}

/// <summary>

internal static class NativeMethods
{
    [DllImport("xmlinterop.dll",
        EntryPoint = "_jdeXMLRequest@20",
        CharSet = CharSet.Auto,
        ExactSpelling = false,
        CallingConvention = CallingConvention.StdCall,
        SetLastError = true)]
    private static extern IntPtr jdeXMLRequest([MarshalAs(UnmanagedType.LPWStr)] StringBuilder server, UInt16 port, Int32 timeout, [MarshalAs(UnmanagedType.LPStr)] StringBuilder buf, Int32 length);

    public static string JdeXmlRequest(XmlDocument xmlInput, string strServerName, UInt16 intPort, Int32 intTimeout)
    {
        StringBuilder sbServerName = new StringBuilder(strServerName);
        StringBuilder sbXML = new StringBuilder();
        XmlWriter xWriter = XmlWriter.Create(sbXML);
        xmlInput.WriteTo(xWriter);
        xWriter.Close();

        string result = Marshal.PtrToStringAnsi(jdeXMLRequest(sbServerName, intPort, intTimeout, sbXML, sbXML.Length));

        return result;
    }
}

}

You have to send it messages like the following one:

<jdeRequest type='callmethod' user='USER' pwd='PWD' environment='ENV'>
  <callMethod name='GetEffectiveAddress' app='JdeWebRequest' runOnError='no'>
    <params>
      <param name='mnAddressNumber'>10000</param>
    </params>
  </callMethod>
</jdeRequest>
