[Former Member]

Hi All,

Need to config the fill name at runtime from server

for ex: on server there is file  i.e ABC.txt nd in output it would be ABC(data till .)

i/p: ABC.txt

o/p: ABC

if anyone know about it then let me know

Thanks in advance.!!

Thanks to all for providing possbile solutions,

I have wrote the UDF for it and in channel in ASMA property i copy the file directory,

used UDF as below,

String SourceFileName = new String("");

DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System","FileName");

SourceFileName = conf.get(key);

1. conf.put(key,SourceFileName);

return SourceFileName;

Thanks,

Ajay

Hi Ajay,

               Please use this java mapping in ESR after all graphical mappings in the same Operation mapping.

package com.javaMapping;  
import java.io.BufferedReader;  
import java.io.IOException;  
import java.io.InputStream;  
import java.io.InputStreamReader;

import com.sap.aii.mapping.api.DynamicConfiguration;  
import com.sap.aii.mapping.api.DynamicConfigurationKey;  
import com.sap.aii.mapping.api.StreamTransformationException;  
import com.sap.aii.mapping.api.TransformationInput;  
import com.sap.aii.mapping.api.TransformationOutput;  
public class DynamicFileName_JavaMapping extends AbstractTransformation {  
     private static final DynamicConfigurationKey KEY_FILENAME =  
           DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");  
    @Override  
    public void transform(TransformationInput in, TransformationOutput out)  
            throws StreamTransformationException {  
        // TODO Auto-generated method stub  

        String newFileName = null;  




          DynamicConfiguration conf = in.getDynamicConfiguration();  
          String oldFileName = conf.get(KEY_FILENAME);               

          newFileName = oldFileName.replaceAll(".txt", "");  



          String inData = convertStreamToString(in.getInputPayload().getInputStream());  
          String outData = inData;  
          try {  
            out.getOutputPayload().getOutputStream().write(outData.getBytes("UTF-8"));  
        } catch (UnsupportedEncodingException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        } catch (IOException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }  
          conf.put(KEY_FILENAME,newFileName);  
    }  
      public String convertStreamToString(InputStream in){  
            StringBuffer sb = new StringBuffer();  
            try  
            {  
            InputStreamReader isr = new InputStreamReader(in);  
            Reader reader =  
            new BufferedReader(isr);  
            int ch;  
            while((ch = in.read()) > -1) {  
                sb.append((char)ch);}  
                reader.close();  
            }  
            catch(Exception exception) { }  
            return sb.toString();  
            }  
}  

Please tick on ASMA filename in sender and receiver file adapter.

Hi Ajay,

If you are not using ESR objects, you can deploy Eng Swee Yeoh module bean: DynamicAttributeChangeBean - The no-mapping sol... | SCN

i m using ESR object

Hi Ajay

If you want file name in the receiver file adapter then use dynamic configuration in the mapping if you're u have mapping

yes i have mapping but i have to write udf at recvr side field for that there is no field from sender side.

so without sender field how i pick up the file  at recever side

[former_member187339]

Hi Ajay,

Check the first UDF in the following link

To invoke the UDF, do a mapping like this

<source message type or Header Node in Source XML Structure> --- UDF --- <target message type or Header Node in Target XML Structue>

Make sure Dynamic Configuration (Filename) is selected in both source and target channel.
