idoc java_java - 将iDOC从Java发送到SAP - 堆栈内存溢出

我们有从系统生成的iDOC文件。 现在，我们尝试通过RFC连接将它们发送到SAP。 我已经作为客户端建立了RFC连接，但无法发送iDOC！

我试图创建一个样本iDOC进行测试，但是它不起作用！

我什至尝试发送样本iDOC XML，但我也遇到了另一个错误，试图多次更改XML，但是我又一次遇到了同样的问题！

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：

我正在使用sapjco3-x86-64bit-3.0.5和sapidoc-3.0.1！

测试iDOC的创建并发送IDOC XML仅用于测试，但在本例中，我们已经准备好了iDOC！

我的问题是，如何通过RFC将iDOC 从磁盘直接发送到SAP？ 如果无法这样做，如何解决创建iDOC或发送iDOC XML的错误？ 我的第二个问题，一旦我能够发送iDOC，是否必须建立一个新的SERVER RFC连接，以便可以从SAP接收iDOC？

** 编辑 **

现在，我可以正确发送和接收IDoc。 我的问题是如何将IDoc作为Flat IDoc获得 。

我可以使用以下代码将IDoc作为XML IDoc接收：

package com.idoc.actif;

import com.sap.conn.idoc.IDocDocumentList;

import com.sap.conn.idoc.IDocXMLProcessor;

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

import com.sap.conn.jco.server.*;

import java.io.IOException;

import java.io.OutputStreamWriter;

{

public static void main(String[] a)

{

try

{

// see provided examples of configuration files xxxx.jcoServer and xxxx.jcoDestination

JCoIDocServer server = JCoIDoc.getServer("xxxx");

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)

{

FileOutputStream fos=null;

OutputStreamWriter osw=null;

try

{

//receiving XML IDoc, how to get the IDoc as a Flat IDoc (SAP is sending the IDoc as Flat)???

IDocXMLProcessor xmlProcessor = JCoIDoc.getIDocFactory().getIDocXMLProcessor();

fos=new FileOutputStream(serverCtx.getTID());

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();

}

}

}
