I am newcomer to SAP and JCo programming. Based on your JCo development manual, I have started working with JCo. I am now trying to get the details from SFLIGHT using BAPI FLIGHT, but I keep getting a NULLPOINTER EXCEPTION. Please help me out with these, and it would also be helpful if you could suggest a good book for working on JCo.
Null pointer exceptions usually indicate that you simply forgot to initialize an object. Without having your source code there is nothing much that I can recommend here. As far as a book is concerned, my tutorial (available for free by sending me an email) is still the only useful documentation to my knowledge. that I have seen.
