Java mapping in realtime

[viswanahreddy]

I am trying to implement Java mapping from the below blog.

while implementing in PI is it required to mention the filename(C:/Apps/my folder/ppn/training/test.xml) in programming, if so why we require it. Without that cant we directly implement directly? In real time how we use it please explain

Annapur,

The test.xml is required to test run java mapping on your system. You can save test.xml on your desktop and give that path in Java code. When it is executed on SAP PI system, it is not required.

If you are new to Java Mapping, please check these blogs

Thanks for the quick response Raghu.

I will go through the links provided by you.

I was trying to learn the below classes but finding it difficult to learn all the methods to use it in out Java mapping.

I am eager to learn to learn all the stuffs, can i get any links for clear understanding of the below...

AbstractHelper
AbstractTrace	A mapping can use an instance of AbstractTrace to add messages to the trace.
AbstractTransformation	Each XI Java mapping program must extends this abstract class.
DynamicConfiguration	A DynamicConfiguration is a map containing adapter specific message attributes.
DynamicConfigurationKey	A DynamicConfigurationKey denotes an adapter specific message attribute.
InputHeader	Access to fields of the message header.
InputParameters	Access to input parmeter of the mapping.
InputPayload	Access to input payload of the mapping.
OutputHeader	Access to set to fields of the message header.
OutputParameters	Access to output parmeter of the mapping.
OutputPayload	Access to input payload of the mapping.
TransformationInput	Access to all input data of the mapping.
TransformationOutput	Access to all output data of the mapping.

these are api's provided by SAP.  you need to have some knowledge on core java like oops concept, interfaces, classes and abstract classes.

then you will get an idea on how to wrap and use them.

try to learn some basics it is old one.

in java mapping you will implement one method that will take input and output parameter. whatever comes into java mapping that will be input and output will be after you are done with your logic.
