I'm designing some jsp and servlet apps that will be used to extend some of the functionalities of php-based site on linux platform. I have tomcat 3.2 b6 working fine, should I stay with this or try to 4.0 beta? How is 3.2 vs 4.0 in terms of 1. performance 2. scalabilty 3. memory 4. Stability I'm trying to keep everything very low cost (free) in the great tradition of LAMP (Linux Apache Mysql Php) IBM vs Sun/Blackdown (currently using blackdown jdk 1.3) Jikes vs other free compilers? Comments are very welcome Thanks in advance
