SAP E-commerce for ERP in Netweaver CE 7.3

Hi,

We've CE 7.3 and need to implement SAP E-commerce for ERP (not CRM) B2B scenario. Is SAP E-commerce web application compatible with CE 7.3 or does it work only with Netweaver 7.0 java stack? As it is built on Struts 1.1 and developed using JDK 1.4.2, does it work with CE 7.3 which uses JDK 1.6 or higher?

We currently have NWDI 7.0 and NWDS 7.0 SP18. Can we use NWDS 7.0 SP18 and NWDI 7.0 for E-commerce development and deploy on CE 7.3? Or should we upgrade to NWDS 7.3 and NWDI 7.3?

Have anyone successfully deployed SAP E-commerce B2B scenario on CE 7.3?

Thanks

Kumar
