将iDOC从Java发送到SAP

Question

我们有从我们的系统生成的iDOC文件。现在，我们正试图通过RFC连接将它们发送到SAP。我已经建立了一个RFC连接作为一个客户端，但我无法发送iDOC！

我尝试创建一个示例iDOC来测试它，但是它不起作用！

Exception in thread "main" java.lang.NoSuchMethodError: com.sap.conn.idoc.jco.SAPRepository$ConnectionProvider.execute(Lcom/sap/conn/jco/JCoFunction;Lcom/sap/conn/jco/rt/AbapRepository;)V

我甚至试着发送一个示例iDOC XML，但我也面临着另一个错误，多次尝试更改XML，但我再次面临同样的问题！

com.sap.conn.idoc.IDocParseException: (7) IDOC_ERROR_PARSE_FAILURE: Invalid character encountered in XML input data source:

这是我用来创建iDOC和发送iDOC XML的代码：

package com.idoc.sender;


import com.sap.conn.idoc.*;
import com.sap.conn.idoc.jco.JCoIDoc;
import com.sap.conn.jco.JCoDestination;
import com.sap.conn.jco.JCoDestinationManager;

import java.io.BufferedReader;
import java.io.FileReader;


public class IDocClientExample {

 public static void main(String[] args) {

  try {

   String iDocXML = null;
   FileReader fileReader;

   try {
    fileReader = new FileReader("TestSalesOrder.xml");
    BufferedReader br = new BufferedReader(fileReader);
    StringBuffer sb = new StringBuffer();
    String line;
    while ((line = br.readLine()) != null) {
     sb.append(line);
    }

    iDocXML = sb.toString();

    br.close();
    fileReader.close();
   } catch (Exception ex) {
    ex.printStackTrace();
   }

   // see provided configuration file xxxx.jcoDestination
   JCoDestination destination = JCoDestinationManager.getDestination("xxxx");
   IDocRepository iDocRepository = JCoIDoc.getIDocRepository(destination);
   String tid = destination.createTID();
   IDocFactory iDocFactory = JCoIDoc.getIDocFactory();

   System.out.println(destination.getAttributes());


   // a) create sample new idoc
   IDocDocument doc = iDocFactory.createIDocDocument(iDocRepository, "SYSTAT01");
   IDocSegment segment = doc.getRootSegment();
   segment.addChild("E1MARAM");
   JCoIDoc.send(doc, IDocFactory.IDOC_VERSION_DEFAULT, destination, tid);


   // b) use existent xml file
   IDocXMLProcessor processor = iDocFactory.getIDocXMLProcessor();
   IDocDocumentList iDocList = processor.parse(iDocRepository, iDocXML);
   JCoIDoc.send(iDocList, IDocFactory.IDOC_VERSION_DEFAULT, destination, tid);
   destination.confirmTID(tid);

  } catch (Exception e) {
   e.printStackTrace();
  }
  System.out.print("program end");
 }
}
// a) create sample new idoc
IDocDocument doc = iDocFactory.createIDocDocument(iDocRepository, "SYSTAT01");
IDocSegment segment = doc.getRootSegment();
segment.addChild("E1MARAM");
JCoIDoc.send(doc, IDocFactory.IDOC_VERSION_DEFAULT, destination, tid);


// b) use existent xml file
IDocXMLProcessor processor = iDocFactory.getIDocXMLProcessor();
IDocDocumentList iDocList = processor.parse(iDocRepository, iDocXML);
JCoIDoc.send(iDocList, IDocFactory.IDOC_VERSION_DEFAULT, destination, tid);
destination.confirmTID(tid);

} catch (Exception e) {
 e.printStackTrace();
}
System.out.print("program end");
}
}

这是我的连接文件：

jco.client.lang=EN
jco.client.client=100
jco.client.passwd=xxxx
jco.client.user=xxxx
jco.client.sysnr=01
jco.client.ashost=xxxx

这是我的xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<DEBMAS06>
<IDOC>
<EDI_DC40>
<DOCNUM>20120114120000</DOCNUM><IDOCTYP>DEBMAS06</IDOCTYP>

我使用的是皂甙3-x86-64位-3.0.5和皂甙-3.0.1！

测试iDOC的创建和发送IDOC只是为了测试，但是在我们的例子中，我们已经准备好了iDOC！

我的问题是，如何通过RFC将iDOC 直接从磁盘发送到SAP？如果我不能这样做，我如何避免创建iDOC或发送iDOC XML的错误？我的第二个问题，一旦我能够发送iDOC，我是否必须建立一个新的服务器RFC连接，以便我可以从iDOC接收iDOC？

** 编辑 **

现在我能够正确地发送和接收IDoc。我的问题是如何将IDoc作为一个平面IDoc来获得。

我可以使用以下代码接收我的IDoc作为XML IDoc：

package com.idoc.actif;

import com.sap.conn.idoc.IDocDocumentList;
import com.sap.conn.idoc.IDocXMLProcessor;
import com.sap.conn.idoc.jco.*;

            server.addServerErrorListener(listener);
            server.addServerExceptionListener(listener);
            //server.setConnectionCount(1);
            server.start();

        }

Answer 1

我猜您使用的两个SAP库之间可能存在不兼容性。我建议首先安装最新的修补程序级别。目前，这是JCo版本3.0.17和IDoc库3.0.12。

我只是不明白你在用StringBuffer做什么。如果您想从文件中读取IDoc-XML，那么IDocXMLProcessor提供了适当的解析方法--最好是

IDocXMLProcessor.parse(IDocRepository repository, InputStream xmlStream)

这样，它还可以处理在包含的XML编码属性中指定的不同文件编码。如果您选择了一个java.io.Reader或一个字符串，那么您必须自己处理这个问题(在您的示例中没有这样做)。

但原则上，您的代码乍一看似乎没有错。与IDoc本身不同的是，IDoc本身缺乏针对和BEGIN=标记的强制性SEGMENT="1“和SEGMENT=”1“属性。
