I have been asked to interface a .Net application with SAP. We are in the process of implementing SAP 7.1. I was planning on using Web Services, but I have been told that we did not implement the Java stack so the web services are not available. I'm not really sure how to proceed. Are there any other avenues that offer interoperability?
If we were to implement the Java stack would it be reasonable to implement one Java based ECC server for all our ABAP server environments or would I need to have one for each environment?
