Error in File scenario

Question

I am doing File->File Scenarios. There is no Recrod set also. I want to rename the file using XI. No mapping required. To rename the File name we can do the coding related to Dynamica configuration in one UDF and will map to the top node of the target. But i don't have the mapping here, So How can i execture this UDF or Do i need to write the Module in File adapter CC.
I tried with dummy mapping , But I am getting the following error
</SAP:Category>
<SAP:Code area="MAPPING">EXCEPTION_DURING_EXECUTE
</SAP:Code>
<SAP:P1>com/sap/xi/tf/_MM_Target_File_determined_
</SAP:P1>
<SAP:P2>com.sap.aii.utilxi.misc.api.BaseRuntimeException
</SAP:P2>
<SAP:P3>Fatal Error: com.sap.engine.lib.xml.parser.Parser~
</SAP:P3>
<SAP:P4/>
<SAP:AdditionalText/>
<SAP:ApplicationFaultMessage namespace=""/>
<SAP:Stack>During the application mapping com/sap/xi/tf/_MM_Target_File_determined_ a com.sap.aii.utilxi.misc.api.BaseRu
ntimeException was thrown: Fatal Error: com.sap.engine.lib.xml.parser.Parser~
</SAP:Stack>
The mapping part is correct. There is no doubt on that. I don;t know why i am getting this error. Can you please tell me what could be the reason or any solution to resolve my problem.

Hi,
Use Java Mapping instead of GraphicalMapping with UDF.
The purpose of JavaMapping is to bypass the inputstream to outputstream along with Dynamic Configuration code which meant for renaming the picked source file name according your requirement
Code:
import com.sap.aii.mapping.api.StreamTransformation;
import java.io.*;
import java.util.Map;
public class RenameSourceFile
    implements StreamTransformation
    public RenameSourceFile()
    public void setParameter(Map map1)
        map = map1;
    public void execute(InputStream inputstream, OutputStream outputstream)
        try
          DynamicConfiguration conf = (DynamicConfiguration) param.get("DynamicConfiguration");
          DynamicConfigurationKey KEY_FILENAME = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
          ourSourceFileName = conf.get(KEY_FILENAME);
//logic to rename the file name - do it according to your requirement
          // put the filename in below statement
          conf.put(KEY_FILENAME, "ModifiedFileName");
          String s = null;
          BufferedReader bufferedreader = new BufferedReader(new InputStreamReader(inputstream));
          StringBuffer stringbuffer = new StringBuffer();
          while((s = bufferedreader.readLine()) != null)
               outputstream.write(s.getBytes());
        catch(Throwable throwable)
            throwable.printStackTrace();
    private Map map;
Thanks,
