Java for UDF's

[Former Member]

Hi

Kindly guide me towards some basic principles or guidelines to master writing UDF's.

I have neither a Java nor an ABAP background,but i have begun SAP PI and done some straight one to one mappings and some idoc scenarios as well

Actually i want to know , the extent to which i have to know Java,If i am required to even begin learning basic Java ..what all should i basically cover and some pointers from you on the same.

I want to do selective study on Java topics so that I can learn and practise UDF's

I need some help and basic starting steps for writing effective user defined functions.

Do I have to be a Java expert to write UDF's , I actualy want to learn and master the concept of queues and contexts and consequently result lists etc.

Thanks

Basic Core java , mainly with String functions

and other methods is more than enough

For writing complex UDFs, java mapping or adapter module, learning java is very important. You need just Core java knowledge initially but for adapter modules advanced java knowledge is also required. Most important is to understand the Object Oriented concepts for the language and then the syntax could be found anywhere.
