The current version of DD4T (ver 2.0.3) uses a lot of java servlet 3.0 features including dispatcher type, etc. However our deployment environment is WebLogic 11g, which uses the servlet 2.5. This is also true for DXA. We want to use DD4T 2 or DXA with its JSON support. Instead of modifying the source code, is there any other implementation of DD4T 2 that can support java servlet 2.5?
