Hi, We are making an application using Weblogic Server 6.0. We need to integrate this Enterprise Application (EJBs, servlets etc.) to back-end legacy systems. As of now I don't know what the legacy systems would be ( Seibel is going to be used for CRM). What is the best way to integrate with back-end legacy systems regardless of whether it is an ERP, mainframe, seibel or any other legacy system. I have been reading on this & found out a few possible ways. I think we can use Tuxedo or Java Adapter for mainframes or CORBA based integration. What would be the best way to integrate to the legacy system ? Thanx, Vikram.
