Answer 1

Hi, The reason tomcat had to be used is that the software is bundled with tomcat. Hence we are in the following configuration:
-Sun Web Server 7.0 update 5
-Tomcat 6, Using JRE1.6
-The server runs Linux.
-As for the tomcat web server plugin, the 32-bit tomcat connector is downloaded from http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/solaris/jk-1.2.26/sparc/
With this configuration. seems when we refresh a page quickly, we get "service unavailable error". But if we only put web contents, the issue does not exist. Looks like the issue resides in the plugin....
Any help is greatly appreciated
