We are reviewing a number of portal engines for our intranet. Many of them are JAVA based sytems. We have a small number of servlets and web services written in JAVA that will remain in place(using JRUN) We also use PeopleSoft in HR. I am proposing we go with .NET to build our new portal intranet. Any cons to interacting with servlets and or PeopleSoft or other items in general? Would you guys reccommend a .NET initiave knowing some servlets will remain?
