If I start Tomcat without the virtual host, I get Starting service Tomcat-Standalone Apache tomcat/4.0 Starting service Tomcat-Apache Apache tomcat/4.0 Using Tomcat 3.2 and Apache 1.3.19, I had no trouble managing this virtual host And trying to compile mod_webapp, after ./configure I get : APR buildconf : autoconf not found (Linux MDK 7.2 with kernel 2.4.9) Dom
