1)compiling the apr, it need an option --disable-threads otherwise the mod_webapp.so cann't be loaded by apache, it said: undefined symble:pthread_sigmask 2) in the jakarta-tomcat-connectors/webapp/docs/apache-1.3.html state: LoadModule webapp_module libexec/mod_webapp.so AddModule webapp_module //this is really really a problem!!// //it must not be present here. WebAppConnection myConnection warp localhost:8008 WebAppDeploy examples myConnection /examples/ 3) how to config the server.xml and httpd.conf correctly? the last WebAppDeploy statement must be put into a <VirtualHost> section? I can see http://localhost/examples/ , but http://localhost/examples/jsp/num/numguess.jsp does not work properly, without any response. 4) would the developer of j-t-c develop a version of apache-2.0.X?? any response is appreciative thanks Mit freundlichen Gruessen Shanghai China Ren Weili <mailto:[EMAIL PROTECTED]> TEL : 0086-21 5956-1888x62686 FAX : 0086-21 5957-7922
