remove extension .pgp with out mapping after decryption

[former_member355445]

HI all ,

i have a requirement , i need to decrypt the PGP file and place it in a local NFS directory, with out any mapping

Scenario: file (NFS) to file (NFS)

initally the file will be like BR_AXBT_123.csv.pgp , after decrypting the file , the file should be placed in the target with the file name BR_AXBT_123.csv

please help me on this, how to achieve this

Thanks,

Viany.

Hi Vinay,

As Manoj mentioned, there is no slandered way to achieve this without mapping. You can try with java mapping.

I had same requirement and implemented with java mapping.

can you please share the java mapping

Hi Vinay,

You can try with the below java code. It will work perfectly fine for your requirement.

create a jar file and import it to imported archive.

Code:

import java.io.InputStream;

import java.io.OutputStream;

import java.util.Map;

import com.sap.aii.mapping.api.AbstractTransformation;

import com.sap.aii.mapping.api.DynamicConfiguration;

import com.sap.aii.mapping.api.DynamicConfigurationKey;

import com.sap.aii.mapping.api.StreamTransformationConstants;

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

{

public void transform(TransformationInput transformationInput, TransformationOutput transformationOutput)

                                                                        throws StreamTransformationException

{

  try

  {

   InputStream inputstream = transformationInput.getInputPayload().getInputStream();

   OutputStream outputstream = transformationOutput.getOutputPayload().getOutputStream();

   Map mapParameters = (Map) transformationInput.getInputHeader().getAll();

   // a) Set Output File name

   mapParameters.put(DynamicConfigurationKey.create("http://sap.com/xi/XI/Dynamic",StreamTransformationConstants.DYNAMIC_CONFIGURATION), "");

   DynamicConfiguration conf = (DynamicConfiguration) mapParameters.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

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

  String Fname=conf.get(key);

  int length=Fname.length();

  int index=length-8;

  String newName=Fname.substring(0,index);

   //Depending on your requirement edit this logic. Here, NewDynamicName + CurrentDate will be output file name.

     conf.put(key, (newName+".csv"));  //or we can try .txt

   // b) Just copy Input file content to Output file content

   byte[] b = new byte[inputstream.available()];

   inputstream.read(b);

   outputstream.write(b);

  } catch (Exception exception)

  {

   getTrace().addDebugMessage(exception.getMessage());

   throw new StreamTransformationException(exception.toString());

  }

}

}

you can check the below blog as well for this requirement.

Hi Vinay,

I know Guarav already supplied a mapping but here is a different implementation that works for both adding and removing extensions in the case you later have to add an extension for a PGP encrypted file.  It makes use of two parameters for the mapping named MODE and VALUE.

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.IOException;

import com.sap.aii.mapping.api.AbstractTransformation;
import com.sap.aii.mapping.api.DynamicConfiguration;
import com.sap.aii.mapping.api.DynamicConfigurationKey;
import com.sap.aii.mapping.api.MappingTrace;
import com.sap.aii.mapping.api.StreamTransformationException;
import com.sap.aii.mapping.api.TransformationInput;
import com.sap.aii.mapping.api.TransformationOutput;


public class DynamicConfigurationMap extends AbstractTransformation 
{
  private MappingTrace trace;
  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 
  {
    // Initialize variables, objects for processing
    trace = getTrace();
    BufferedInputStream bis = new BufferedInputStream(in.getInputPayload().getInputStream());
    BufferedOutputStream bos = new BufferedOutputStream(out.getOutputPayload().getOutputStream());

    // access dynamic configuration
    DynamicConfiguration conf = in.getDynamicConfiguration();
    String filename = conf.get(DynamicConfigurationMap.KEY_FILENAME);
    if(filename == null || filename.compareTo("") == 0)
    {
      throw new StreamTransformationException("Invalid or missing filename");
    }

    // Getting java mapping input parameter for mode and value
    String mode = in.getInputParameters().getString("MODE");
    String value = in.getInputParameters().getString("VALUE");

    if(mode.compareToIgnoreCase("append") == 0)
      conf.put(DynamicConfigurationMap.KEY_FILENAME, filename + value);
    else if(mode.compareToIgnoreCase("remove") == 0)
      conf.put(DynamicConfigurationMap.KEY_FILENAME, filename.replaceFirst(value, ""));
    else
    {
      throw new StreamTransformationException("Unsupported mode: " + mode);
    }

    // Transfer input stream to output stream without modification
    int theInt;
    try {
      while((theInt = bis.read()) != -1)
      {
        bos.write(theInt);
      }
      bos.flush();
      bis.close();
      bos.close();
    } catch (IOException e) {
      throw new StreamTransformationException("Error transferring input stream to output stream", e);
    }
  }
}
