Exception Caught!! payloadName Error!!

[#1]

Hello Experts,

     My Scenario is IDoc to Mail. I need to send the file as an attachment with dynamic filename and body. I am able to send the the file with attachment and body but not with the dynamic filename. Also  I am not supposed to use Mail Package.So for the reason I have implemented Module code for changing the dynamic filename.Here is the code and error exception occurred in the Message Log.

Module Code:

package com.sap.mailmodule;

import javax.ejb.Stateless;

import com.sap.aii.af.lib.mp.module.ModuleContext;

import com.sap.aii.af.lib.mp.module.ModuleData;

import com.sap.aii.af.lib.mp.module.ModuleException;

import com.sap.engine.interfaces.messaging.api.Message;

import com.sap.engine.interfaces.messaging.api.MessageKey;

import com.sap.engine.interfaces.messaging.api.MessagePropertyKey;

import com.sap.engine.interfaces.messaging.api.Payload;

import com.sap.engine.interfaces.messaging.api.PublicAPIAccessFactory;

import com.sap.engine.interfaces.messaging.api.auditlog.AuditAccess;

import com.sap.engine.interfaces.messaging.api.auditlog.AuditLogStatus;

/**

* Session Bean implementation class MailAdapterModule

*/

@Stateless

public class MailAdapterModule implements MailAdapterModuleRemote, MailAdapterModuleLocal

{

    public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData)throws ModuleException

    {      

        Message msg = (Message) inputModuleData.getPrincipalData();

        MessageKey key = null;

        AuditAccess audit = null;

        String attName = null;

        String targetFileName = null;

        try

             {          

             //Custom Adapter module  : Module called

            //Reading file name from message header

            attName = moduleContext.getContextData("AttachmentName");

            Payload payload = msg.getAttachment(attName);                  

            MessagePropertyKey fileKey = new MessagePropertyKey("FileName","http://sap.com/xi/XI/System/Mail");

            targetFileName = fileKey.getPropertyName();

             audit = PublicAPIAccessFactory.getPublicAPIAccess().getAuditAccess();

            audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, "Input file read successfully");

            //Reading the Directory Names from the Module Context           

            if(targetFileName == null)

            {

                targetFileName = "Reservation.txt";

            }

            audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, " Name of Attachment after msg.getattchment method: " + targetFileName);

            audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, " Name of Attachment after msg.getattchment method: " + targetFileName);

            payload.setName(targetFileName);

            audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS,"Attachment renamed successfully : " +targetFileName);

            audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, " Entering Mail Adapter");

             inputModuleData.setPrincipalData(msg);

            }

        catch (Exception e)

        {

            throw new ModuleException(e);

        }

     return inputModuleData;

    } 

}

Hi everyone/Eng,

I have adjusted the code as per your previous reply and the deployment is successful after the import with the latest change. Now while testing the same the attachment name for the file is still "MainDocument.txt". But the message log is displaying Attachment renamed successfully. Please find the below screen shot of the same!!

Hi Prashanth

Your logic does not do any renaming of the attachment. It just retrieves the attachment name from dynamic configuration (which was stored by mapping) and does nothing to it, it is just kept in the variable targetFileName.

In order to set the filename of the attachment, you need to set it in the Content Type of the attachment. The content type needs to be set in the following format, assuming you are only dealing with plain text MIME types.

text/plain;charset="UTF-8";name="file.txt"

To do this, you need to use setContentType() method of the Payload interface. For your case, you can do something like below:-

payload.setContentType("text/plain;charset=\"UTF-8\";name=\"" + targetFileName + "\"");

Make sure this is after the variable has been populated.
