Exception Caught!! payloadName Error!!

[Former Member]

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:

Hi Eng,

Apologies for the delay!!!

Thanks for your Patience and reply.

As per your previous blogs, I have splitted the requirement in to two flows. Here are the below details.

1.IDOC-PI-SOAP

2.SOAP-PI-MAIL

In the first flow I have created one node MAIL with the fields THeaderTo, THeaderCC, THeaderSubject, FileName underneath to it.

In the second flow I have used content conversion in SOAP Channel and then in the Mapping part I have used Java mapping with dynamic configuration parameters with all the above MAIL fields.

Also the first of the flat file I have replaced with blank data instead of MAIL field values and used While loop for multiple Item occurrences.

This is the way we have completed it Eng with out constructing any MIME parameters in JAVA mapping.

Please let me know if you need in detail with screenshots so that i can share the same.

Also will try your case and update you soon.

Thanks in advance!!

Many Thanks,

Hi Prashanth

That's fine. I was just curious if setting the Content-Disposition helped resolved your issue, since that worked for me.

Anyway, if your issue has been been fully resolved, I'd suggest that you close this thread.

Hi Prashanth

Were you able to resolve this in the end?

I believe setting the content disposition should resolve it. I've also mentioned this in my post below.

[Former Member]

Hi Eng,

     Thanks for the reply!!! Is it better idea to include the above two lines of code and test or add the payload.setname and test and if if does not work again adding the payload.contentdisposition one time.

Also I have added the code like below!! Kindly suggest the same whether i can proceed.

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

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

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

            payload.setName(targetFileName); 

            payload.setAttribute("content-disposition", "attachment;filename=\"" + targetFileName + "\"");

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

            inputModuleData.setPrincipalData(msg); 

Will try the same and deploy it and get back to you!!

Thanks again for the patience!!

Many Thanks,

I would suggest you do it one at a time so that you can identify the root cause of the issue.

Code looks ok, try deploying and test it again.

HI Eng/

    Sorry for the late and refrain!! I have added the MessageLoggerBean in the channel after my custom module. Please find the below screenshots of the same.

Communication Channel Setting:

PIMON Screenshot Step 2:

PIMON Screenshot Step 2:

From the above screenshots i have provided the log details from PIMON and also the data inside the attachment. And from the body attachment it will be converted to mail body.Would request you to kindly help on the same and let me know whether i need to change any module code.

Also Please suggest me if i need to try with attachment api's in the module code.

Kindly help on the same.

Hi Prashanth

Unfortunately, different mail providers act differently on the MIME details, so it is always a trial and error.

For your mail server, it looks like the content type is not enough, so let's try a few more things.

1. Set payload name

Add the following to your code at the appropriate position.

payload.setName(targetFileName);

Then retest your case.

If it still does not work, try below

2. Set content disposition

Add following code in addition to above

payload.setAttribute("content-disposition", "attachment;filename=\"" + targetFileName + "\"");

If it still does not work, provide the same screenshot for the Attachment tab of the logged version.

Hi all/Eng,

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.

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.

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.

            throw new ModuleException(e);

    } 

}

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!!!

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/ 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!!!

[engswee]

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?

[former_member182412]

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.

[justin_santhanam]

Hello Prashanth,

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

>>Also  I am not supposed to use Mail Package

Thanks!

[engswee]

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

[justin_santhanam]

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

[engswee]

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?

[iaki_vila]

Hi Prashanth,

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

Regards.

[Former Member]

Hi Vila,

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

1. attachment.setName("VODAFONETR-attachment1"); 
2.   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!!
