JDEdwards XMLInterop

Question

我想知道是否有人已经成功地使用了JDEdwards XMLInterop功能。我已经使用它一段时间了(只有一个简单的PInvoke，稍后会发布代码)。我正在寻找是否有更好和/或更健壮的方法。

谢谢。

正如所承诺的，下面是使用XML与JDEdewards集成的代码。它是一个see服务，但可以按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;
    }
}

}

您必须向它发送如下消息：

<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>

对于任何想要这样做的人来说，对xmlinterop.dll都有一些依赖。

你可以在胖客户机上找到这些文件，这里是->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

在看到这段代码后，我将我们的JDE web服务更改为使用XML Interop，从那以后我们就再也没有遇到过任何稳定性问题。以前我们使用的是COM连接器，它经常出现通信故障(可能是连接池问题？)正确安装和配置是一件很痛苦的事情。

当我们尝试使用事务时，我们确实遇到了问题，但如果您正在进行简单的单个业务函数调用，这应该不是问题。

xmlinterop更新：详细说明事务问题-如果您试图在多个调用中保持一个事务的活动状态，并且应用服务器正在处理适度数量的并发调用，则调用将开始返回一条“XML”消息，并且DB事务处于打开状态，无法提交或回滚。调整内核的数量可能会解决这个问题，但就我个人而言，我总是试图在一个调用中完成事务。
