Good afternoon, Can someone please give me some advise... I am having a difficult time getting IIS Isapi Redirector to function properly. I am running IIS 4.0 on Windows NT 4.0 (SP5) and I am hosting 10 different sites off of this server. I configured to ISAPI filter under WWW master properties (Machine name, not root web) and I have verified that the filter is functioning properly ("Green arrrow"). If I access the url http://127.0.0.1:8080/examples/jsp I am able to connect and the examples all run OK. However, if I access the url http://127.0.0.1/examples/jsp I recieve an IIS "HTTP - Internal Server Error 500" if I try accessing the site from a different PC, if I try to access the site localing using the troubled url I recieve the following error message: "Server Application Error The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for assistance. " In the event log an entry is logged with the following details: The server failed to load application '/LM/W3SVC/3/Root/jakarta'. The error was '80040154'. Any help would be GREATLY appreciated... So the final breakdown is that tomcat is functioning fine, but I can't get the redirector to work... PS: Also in my iis_redirect.log I see a few entries that state [jk_uri_worker_map.c (335)]: jk_uri_worker_map_t::uri_worker_map_close, NULL parameter [jk_uri_worker_map.c (185)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL parameters [jk_uri_worker_map.c (335)]: jk_uri_worker_map_t::uri_worker_map_close, NULL parameter [jk_uri_worker_map.c (185)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL parameters [jk_uri_worker_map.c (335)]: jk_uri_worker_map_t::uri_worker_map_close, NULL parameter [jk_uri_worker_map.c (185)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL parameters Thanking you in Advance !! _________________________________________________________ Do You Yahoo!?
