what are the Prerequisites for Java Mapping to start

[AbdulHammed]

Hello Experts,

I have seen lot of blogs related to how to create java mappings in SAP PI/PO but i haven't seen any blog related to how to write a code in java mapping, what do we required (basic knowledge of what????) to write...

I know it's silly because as being a fresher to SAP PI/PO from non-IT back ground i don't know where to start & how to....

the blogs i have seen so far are awesome where i learned about eclipse( download, start, creating a java project... etc.,)

But actual question is how to write a code and what are the prerequisites for it( do i need to learn core & Advance java for it)

Thanks in advance experts.

If you can cover core java(OOPS concepts) then you dont need anything to refer. Java mapping is just extending another class.

Learn about what is class, interface, methods? how to extend class? how to implement interface?.....etc

Google search ,learn and practise java and then come back to sap scn site for java mapping.

Hi,

You can look in following blog for pre-requisites/steps:

• https://blogs.sap.com/2017/11/02/sap-pi-java-map-to-read-file-and-return-it-to-target-message/

And for XML-Trasnformations via Java, you have to use concept of DOM-Parser
