I wanted to know how to start off by understanding SAP architecture (it is defintely huge and complex). Basically, I would like to connect to a SAP system from Java and read data from the SAP system. I understand that a Java connector is needed for this, but wasn't able to find a free trial version - do you know if one exists or how to get one ?.
Also, is there any free SAP trial software that could be used to test this out ? I was looking on the SAP SDN site and there are so many trial softwares, that I didn't know where to start. Also, could you please guide me as to what it takes to read data from a SAP system?
Thx a ton.
