Need resolution fo Nullpointer Exception

[former_member203627]

Hi

I am using Dynamic configuration for getting file name

Error:

RuntimeException in Message-Mapping transformation: Exception:[java.lang.NullPointerException] in class com.sap.xi.tf._I813_Proxy_2_EModMCS_MM_ method DateStamp$[Test, com.sap.aii.mappingtool.tf3.rt.Context@78237823]

I am using following java code but when I am testing the same in mapping.

// get the dynamic values from the container object

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

// create a key to access the Filename parameter

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

//below you access the file name from header if it was set in the sender file channel

//String filename= conf.get(key);

String fileName = IFRECID; // date stamp is an input field to the UDF

// Here you set the fileName(ur datestamp) in the Header of the message

conf.put(key, fileName);

return fileName;

Please help ! ! !

Hi Ria,

Please note that as far as the code is concerned .There are some errors in it.

String fileName = IFRECID; // date stamp is an input field to the UDF

This should be

String fileName = "IFRECID";

In java when u r declaring the String literals the correct syntax must be used.

Please check the message type attributes in the file adapter whether it is perfectly done or not.

Finally do the End to End testing rather than standalone testing in the Message mapping tab.

Thanks

Arijit

Hi

Test this mapping in the Interface mapping test tab and not in the message mapping...

Acknowledge if any error comes/

Hi

I am testing the same in test tab...

[former_member190389]

In the UDF what is the cache that you have selected

Make sure it is "Value" and not context

Are you getting or putting filename?
