Changing the file name dynamicallly in file Adapte...

Former Member · ‎04-26-2007

Hi, I want to change the file name directly from Java Mapping in the file adapter for this i have written this code:

[code]

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

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

String newFileName = CCC'_'NNN'_'NOMCIA'_'DATE;

conf.put(key, newFileName);

return newFileName;[/code]

Where CCC, NNN, NOMCIA and DATE are input of the user-defined function.

but it gives a null pointer exception:

[code]16:44:53 Start of test

The message is: Exception:[java.lang.NullPointerException] in class com.sap.xi.tf._MM_JDBC_2_HSBCAltasTrabajadores_TEST_ method FileName$[123, James, Gates, Spectory, com.sap.aii.mappingtool.tf3.rt.Context@247d247d]
