Built a fouondation in Java, now what?

We built the foundation of our system in Java using Spring and Hibernate and exposing a nice service layer. We used a little bit of Struts for the early front end, but have only developed the tip of the front-end iceberg so far. Now we are at a fork in the road and would love to get your feedback. When developing the front-end (a newspaper-like consumer site) should we: 1) Building it using Struts 2) Develop the site in PHP/Python/Ruby and have it talk to the Java service layer through some bridge technology (like http://php-java-bridge.sourceforge.net) 3) Dump what we've written so far and start from scratch (obviously a difficult one to choose)

Any thoughts?

Thanks, Jay.
