Dynamic Directory Module getting null on getMessageProperty

[former_member540174]

HI - I am testing my custom module and seem to be having trouble retrieving the directory.

On the channel I have populated the filename and directory, checked the Adapterspecific Message-Attributes and checked all there items (Directory included).

I have my module in the Module tab and I see that it is called.

Code is:

Object obj = null;

Message msg = null;

MessageKey key = null;

MessagePropertyKey dirKey = null;

SimpleDateFormat sdfYear = new SimpleDateFormat("yyyy");

SimpleDateFormat sdfMonth = new SimpleDateFormat("MM");

SimpleDateFormat sdfDay = new SimpleDateFormat("dd");

String sYear; String sMonth;

String sDay;

try {

// Calculate Day, Month, and Year

Calendar cal = Calendar.getInstance();

sYear = sdfYear.format(cal.getTime());

sMonth = sdfMonth.format(cal.getTime());

sDay = sdfDay.format(cal.getTime());

obj = inputModuleData.getPrincipalData();

msg = (Message) obj;

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

dirKey = new MessagePropertyKey("Directory",http://sap.com/xi/XI/System/File);

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

//creating object for audit log audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, "AddYMDFolderToEndOfDirectory: New Module called");

// getting Directory from ASMA parameters

dynamicpath = msg.getMessageProperty(dirKey);

audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, "input Directory:" + dynamicpath);

audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, "Year Directory:" + sYear);

audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, "Month Directory:" + sMonth);

audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS, "Day Directory:" + sDay);

Audit Log shows:

10.02.2014 13:46:53.448	Information	Day Directory:10
10.02.2014 13:46:53.448	Information	Month Directory:02
10.02.2014 13:46:53.448	Information	Year Directory:2014
10.02.2014 13:46:53.448	Information	input Directory:null

What might be causing the directory to be null?  What step did I miss?

Regards,

Diane

Hello,

For testing purpose use below code + make sure u have enabled Directory attribute (under ASMA)  in sender file channel

I found three things. One I had forgotten to check the sending adapter ASMA Directory (I'd checked Filename but NOT Directory).  Two my namespace for ASMA was different than the example (http://sap.com/xi/XI/System vs http://sap.com/xi/XI/System/File).  Third I did not have the inputModuleData.setPrincipalData(msg);  

Thank you everyone!

Hi Diane,

I the code which you posted here dynamicpath is not defined any where. Can you check if you defined dynamicpath?

Harish

Hi Diane -

Can you check the code @ http://scn.sap.com/docs/DOC-46112

i see one difference in getting the message property

blog - msg.getMessageProperty("http://sap.com/xi/XI/System/File", "Directory");

your code - MessagePropertyKey("Directory",http://sap.com/xi/XI/System/File);

I've been starring at the code from http://scn.sap.com/docs/DOC-46112 all afternoon comparing it to my code (part of it above).  The code you mentioned was my source and I modified it to meet my needs.  The initial call to get the directory is returning null.  Why would it return null?

Try invoking it directly with the below statement

To read :

dynamicpath = msg.getMessageProperty(dirKey);

change it to

dynamicpath  = msg.getMessageProperty("http://sap.com/xi/XI/System/File", "Directory");

To set :

msg.setMessageProperty(dirKey,dynamicpath);

The difference is the way you pass the parameters while using get method i.e. First namespace follwed by Attribute.

Hi Diane,

Please use mpk = new MessagePropertyKey("Directory","http://sap.com/xi/XI/System/File");

instead of mpk = new MessagePropertyKey("Directory",http://sap.com/xi/XI/System/File);

The msg.getMessageProperty(String arg0, String arg1) is already deprecated.

Hope this helps,
Mark
