JDEdwards XMLInterop

想知道是否有人在使用JDEdwards XMLInterop功能方面取得了成功。我已经使用了一段时间(使用简单的PInvoke,稍后会发布代码)。我想看看是否有更好的和/或更强大的方式。

感谢。

正如所承诺的,这是使用XML与JDEdewards集成的代码。这是一个网络服务,但可以按照您认为合适的方式使用。

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>
/// This interop class uses pinvoke to call the JDE C++ dll.  It only has one static function.
/// </summary>
/// <remarks>
/// This class calls the xmlinterop.dll which can be found in the B9/system/bin32 directory.  
/// Copy the dll to the webservice project's /bin directory before running the project.
/// </remarks>
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;
    }
}

}

您必须向其发送以下消息:

<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>

对于任何尝试这样做的人来说,xmlinterop.dll都有一些依赖关系。

你会在胖客户端找到这些文件 - &gt; c:\ E910 \ system \ bin32

这将创建一个“瘦客户端”

PSThread.dll
icudt32.dll
icui18n.dll
icuuc.dll
jdel.dll
jdeunicode.dll
libeay32.dll
msvcp71.dll
ssleay32.dll
ustdio.dll
xmlinterop.dll

在看到此代码后,我将JDE Web服务更改为使用XML Interop,此后我们没有遇到任何稳定性问题。以前我们使用的是COM Connector,它会出现常规的通信故障(可能是连接池问题?),并且安装和配置都很糟糕。

我们在尝试使用事务时确实遇到了问题,但是如果您正在进行简单的单业务函数调用,那么这应该不是问题。

更新:详细说明事务问题 - 如果您尝试通过多次调用保持事务处于活动状态,并且JDE应用程序服务器正在处理适度数量的并发调用,则xmlinterop调用开始返回“XML响应失败”消息,数据库事务处于打开状态,无法提交或回滚。可能会调整内核的数量可能会解决这个问题,但就个人而言,我总是试图在一次调用中完成交易。
