I have compiled mod_jserv without any problems, but when I restart Apache, I get this error message: httpd: module "mod_jserv.c" is not compatible with this version of Apache. Please contact the vendor for the correct version. I am using Digital Unix 4.0D and Apache 1.3.14. mod_jserv was build from the tomcat 3.2b6 release. The same error msg also came when I tried to use mod_jk. What am I doing wrong? Does anyone have an compile/install procedure that is supposed to work on Digital Unix 4.0 ? SteinL.
