Exception Caught!! payloadName Error!!

Former Member — Thu, 21 Jan 2016 07:41:42 GMT

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;

targetFileName = fileKey.getPropertyName();

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

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

Hi Prashanth,

Have you checked this blog ?, in this blog the code takes the attachment a bit different than you.

Hi Vila,

I agree with you. In your case the file name is static for the attachment. So you have given

attachment.setName("VODAFONETR-attachment1");
attachment.setDescription("VODAFONETR-attachment"); as attachment names.

But in my case i need to set the filename dynamically from ASMA parameters. So i have written the dynamic file name UDF in ESR by using the below code

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

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

conf.put(key,FileName);

From the above code I am putting the filename dynamically to pick by ASMA.

After that in the module level, I have written the following code to get the attachment name.

Payload payload = msg.getAttachment(attName);

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

targetFileName = fileKey.getPropertyName();

payload.setName(targetFileName);

From the above I am getting the attachment and setting it!!

so after giving the above parameters i am facing this error!!

Kindly help!!

Hi Prashanth

The error log does not match the adapter module coding. There is no field named "payloadName" in the logic you provided.

Maybe the error is not due to the custom adapter module. Can you provide the whole message log section for further analysis?

Hello Prashanth,

Just for the understanding what's the reason for the below statement?

>>Also I am not supposed to use Mail Package

Thanks!

Re: Exception Caught!! payloadName Error!!

engswee — Fri, 22 Jan 2016 02:15:52 GMT

SAP encourages usage of ASMA as mail package is deprecated (refer note 856599). My guess is maybe the development team imposes this best practice.

Thanks Eng Swee for the information.. I didn't know about it..

Re: Exception Caught!! payloadName Error!!

Former Member — Fri, 22 Jan 2016 03:19:53 GMT

Hi Prashanth,

You defined the parameter name as Rename.AttachmentName when you reading the parameter in the module you mentioned only AttachmentName

//Reading file name from message header

attName = moduleContext.getContextData("AttachmentName");

Change the below statement

>>>>>targetFileName = fileKey.getPropertyName(); (this will return only property name FileName)

targetFileName = msg.getMessageProperty(fileKey)

Regards,

Praveen.

Former Member — Fri, 22 Jan 2016 05:48:56 GMT

Hi Everyone/ Hi Praveen,

Initially i have provided the setting same as your post. But I am facing the msgkey error. So as a trial and error i just have given the above setting. Here are the below details of my communication channel setting, UDF used in mapping, and module code and error screen shot.

Communication Channel Setting:

Module Code:

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();

payload.setName(targetFileName);

}

UDF used in the mapping:

MappingTrace objTrace = container.getTrace();

DynamicConfiguration objDynConfig;

DynamicConfigurationKey objDCKey;

String Fname = FileName;

objTrace.addInfo(Fname);

final String NAMESPACE = "http://sap.com/xi/XI/System/Mail";

final String ATTRIBUTE1 = "THeaderTO"; //Recipients TO List

final String ATTRIBUTE2 = "THeaderSUBJECT"; // Subject of The Email

//final String ATTRIBUTE3 = "XHeaderName3"; //ContentDisposition

//final String ATTRIBUTE4 = "XHeaderName1"; //ContentType

//final String ATTRIBUTE5 = "XHeaderName2"; //ContentDescription

final String ATTRIBUTE6 = "THeaderCC"; //Recipients BCC List

try

{

objDynConfig = (DynamicConfiguration) container.getTransformationParameters().

get(StreamTransformationConstants.DYNAMIC_CONFIGURATION );

container.setParameter(StreamTransformationConstants.DYNAMIC_CONFIGURATION, objDynConfig);

objDCKey = DynamicConfigurationKey.create(NAMESPACE, ATTRIBUTE1);

objDynConfig.put(objDCKey, ZEmail);

objDCKey = DynamicConfigurationKey.create(NAMESPACE, ATTRIBUTE2);

objDynConfig.put(objDCKey, Subject);

objDCKey = DynamicConfigurationKey.create(NAMESPACE, ATTRIBUTE6);

objDynConfig.put(objDCKey, ZEmailCC);

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

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

conf.put(key,FileName);

}

catch (Exception objException)

{

objTrace.addWarning(objException.getMessage());

}

return "";

Error In the Message Log:

Also as per your previous reply please confirm whether i need to change the module code to

targetFileName = msg.getMessageProperty(fileKey) instead of targetFileName = fileKey.getPropertyName(); or include both.

Kindly help on the same!!!

Re: Exception Caught!! payloadName Error!!

engswee — Fri, 22 Jan 2016 05:54:52 GMT

Your error log still does not match your code. There's no msgKey variable in your logic. And there is no call to method getMessageId() in your logic.

Are you sure the correct module is being called?

Re: Exception Caught!! payloadName Error!!

Former Member — Fri, 22 Jan 2016 06:10:38 GMT

Hi Eng/Hi All,

Yes the correct module is being called.in the As per the earlier screen shot if you could observe the module code and channel setting the same name is given in both. Please find the below screen shots for your reference.

Module code Name screenshot:

Channel Screen shot with same as Module name:

Module code for your reference:

inputModuleData.setPrincipalData(msg);

}

catch (Exception e)

{

throw new ModuleException(e);

}

return inputModuleData;

}

Also as per my understanding from the above error, the error is due to the below line of code is missing in the module code.

key = new MessageKey(msg.getMessageId(), msg.getMessageDirection());

So could you please confirm if i add the above the error could be resolved.

Kindly help on the same.

Thanks in advance!!!

Many Thanks,

Re: Exception Caught!! payloadName Error!!

engswee — Fri, 22 Jan 2016 06:21:35 GMT

Prashanth

Yes, your key is not initialized prior to using the AuditLog.

Add these two lines of code as the first statements in the try block


try
  {
    key = new MessageKey(msg.getMessageId(), msg.getMessageDirection());
    audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, this.getClass().getName() + ": Module Initialized");

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!!

Re: Exception Caught!! payloadName Error!!

engswee — Wed, 27 Jan 2016 06:04:23 GMT

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.

Hi all/Eng,

I have added the same payload.setContentType("text/plain;charset=\"UTF-8\";name=\"" + targetFileName + "\""); in the module code. Still the same issue persists.The attachment name is not getting changed. Here are the below details.

Re: Exception Caught!! payloadName Error!!

engswee — Thu, 28 Jan 2016 06:02:00 GMT

Hi Prashanth

Can you add the module MessageLoggerBean after your custom module so that a version of the payload is available in the logs? Refer to the following on how to do that.

Once you have it logged, can you Open the message in PIMON and provide a screenshot of the Attachments tab for the version that was logged above?

It should look something like below. I would like to see the name and content type for the attachment.
