通过SAPjco + sapidoc3 来实现第3方系统和SAP R3系统进行IDOC的双向传送数据

1.从SAP market上下载sapidoc3和sapjco3下载两个java包

2.jco服务器端代码如下

import com.sap.conn.idoc.*;

import java.io.*;
import com.sap.conn.jco.server.*;
import com.sap.conn.idoc.jco.*;


public class IDocServerExample
{
    public static void main(String[] a)
    {  
        try
        {
            // see provided examples of configuration files MYSERVER.jcoServer and  BCE.jcoDestination
            JCoIDocServer server = JCoIDoc.getServer("MYSERVER");
            server.setIDocHandlerFactory(new MyIDocHandlerFactory());
            server.setTIDHandler(new MyTidHandler());
           
            MyThrowableListener listener = new MyThrowableListener();
            server.addServerErrorListener(listener);
            server.addServerExceptionListener(listener);
            server.setConnectionCount(1);
            server.start();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
     }
   
    static class MyIDocHandler implements JCoIDocHandler
    {
        public void handleRequest(JCoServerContext serverCtx, IDocDocumentList idocList)

        {
            该方法用来侦听SAP的IDOC 端口，如果有idoc发送到该端口，该方法就会把该idoc生成xml文件
            FileOutputStream fos=null;
            OutputStreamWriter osw=null;
            try
            {
                IDocXMLProcessor xmlProcessor =
                    JCoIDoc.getIDocFactory().getIDocXMLProcessor();
                fos=new FileOutputStream(serverCtx.getTID()+"_idoc.xml");
                osw=new OutputStreamWriter(fos, "UTF8");
                xmlProcessor.render(idocList, osw,
                        IDocXMLProcessor.RENDER_WITH_TABS_AND_CRLF);           
                osw.flush();
            }
            catch (Throwable thr)
            {
                thr.printStackTrace();
            }
            finally
            {
                try
                {
                    if (osw!=null)
                        osw.close();
                    if (fos!=null)
                        fos.close();
                }
                catch (IOException e)
                {
                    e.printStackTrace();
                }
            }
        }
    }
   
    static class MyIDocHandlerFactory implements JCoIDocHandlerFactory
    {
        private JCoIDocHandler handler = new MyIDocHandler();
        public JCoIDocHandler getIDocHandler(JCoIDocServerContext serverCtx)
        {
            return handler;
        }
    }
   
    static class MyThrowableListener implements JCoServerErrorListener, JCoServerExceptionListener
    {
       
        public void serverErrorOccurred(JCoServer server, String connectionId, JCoServerContextInfo ctx, Error error)
        {
            System.out.println(">>> Error occured on " + server.getProgramID() + " connection " + connectionId);
            error.printStackTrace();
        }
        public void serverExceptionOccurred(JCoServer server, String connectionId, JCoServerContextInfo ctx, Exception error)
        {
            System.out.println(">>> Error occured on " + server.getProgramID() + " connection " + connectionId);
            error.printStackTrace();
        }
    }
   
    static class MyTidHandler implements JCoServerTIDHandler
    {
        public boolean checkTID(JCoServerContext serverCtx, String tid)
        {
            System.out.println("checkTID called for TID="+tid);
            return true;
        }

   
        public void confirmTID(JCoServerContext serverCtx, String tid)
        {
            System.out.println("confirmTID called for TID="+tid);
        }

   
        public void commit(JCoServerContext serverCtx, String tid)
        {
            System.out.println("commit called for TID="+tid);
        }

   
        public void rollback(JCoServerContext serverCtx, String tid)
        {
            System.out.print("rollback called for TID="+tid);
        }
    }
}

 

以上程序需要server 配置文件和Destination的配置文件如下

server 配置文件格式：

#用来测试!
#2009-06-01
jco.server.connection_count=2
jco.server.gwhost=XXXXXXXX "SAP 服务器 IP
jco.server.progid=JCO_SERVER  "这个可以取个有意义的名字
jco.server.gwserv=sapgw00  "sapgw + SAP 服务器系统编号
jco.server.repository_destination=ABAP_AS_WITH_POOL "Destination的属性的文件名字

 

Destination的配置文件格式：

jco.client.lang=en
jco.destination.peak_limit=10
jco.client.client=200
jco.client.passwd=XXXXX "密码
jco.client.user=XXXXXXX "用户名字
jco.client.sysnr=00   "SAP系统编号
jco.destination.pool_capacity=3
jco.client.ashost=XXXXXX "SAP 服务器 IP

 

3.从jco server发送idoc给SAP
import com.sap.conn.jco.*;
import com.sap.conn.idoc.jco.*;
import com.sap.conn.idoc.*;
import java.io.*;

public class IDocClientExample {

    public static void main(String[] args) {
       
        try
        {
            String iDocXML = null;
            FileReader fileReader;

            try
            {
                fileReader = new FileReader("MyIDocDocumentAsXML.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 BCE.jcoDestination
            JCoDestination destination=JCoDestinationManager.getDestination("ZATF91");
            IDocRepository iDocRepository = JCoIDoc.getIDocRepository(destination);
            String tid = destination.createTID();
            IDocFactory iDocFactory = JCoIDoc.getIDocFactory();
           
            // a) create new idoc
            //IDocDocument doc = iDocFactory.createIDocDocument(iDocRepository, "MATMAS02");
            //IDocSegment segment = doc.getRootSegment();
            //segment = segment.addChild("E1MARAM");
            // and so on. See Idoc Specification .....
            //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");
    }
}

 

4.在SM59里创建RFC Des之前先把Jco server的代码运行起来，能建立jco server和SAP的连接

 

 

图中的Program ID 必须和jco server 属性文件里的jco.server.progid所指定的名字一致。在sap里定义IDOC的port都必须用该DES，这样jco server才能接受idoc

 

用SMGW来查看jco server是否登陆SAP
