Re: [Newbie] Failed access to servlet via URL mapping (context setting problem?)
I notice you are using 1.4.2 Does the compat install mean you set it up to use 1.4 in place of the 1.5 per RUNNING.txt? Doug - Original Message - From: "Geoffrey Charters" <[EMAIL PROTECTED]> To: Sent: Saturday, January 15, 2005 11:47 PM Subject: [Newbie] Failed access to servlet via URL mapping (context setting problem?) Mac OSX 10.3.7; Tomcat 5.5.4; JDK 1.4.2; compat installed I have installed Tomcat 5.5.4 with a view to using it to implement a web-based interface to a MySQL database. I began by following the guidelines here: http://developer.apple.com/internet/java/tomcat1.html, but as these related to V4 of tomcat, this has served to trip me up a little. I could not get any of the example servlets to function by following the directions given. I subsequently found further guidelines here: http://www.coreservlets.com/Apache-Tomcat-Tutorial/, I have got to the point where I can run all of the sample servlets described there. These involve directly copying resources into the $CATALINA_HOME/webapps/ROOT/WEB-INF(/classes) directories. I could now develop my application and copy it to the ROOT directory and access it through a URL like localhost:8080/hi, but this seems like poor structure to me. I could also place the app in a subdirectory and access it with localhost:8080/hi/servlet/hi, but that is not too tidy. What I would like to do, and what I think is possible, is somehow to advise tomcat of the location of my webapp in its own directory (not under ROOT) and access it with localhost:8080/hi. No amount of tweaking servlet mappings and URL patterns has worked, and I suspect that somewhere I need to have a element. (I admit to confusion over the apparent need to specify the path both in the context and the servlet mapping, so I've missed a big point somewhere). The nearest I have got is to obtain an empty "Directory listing for /" page in response to my http://localhost:8080/hi request. I enabled request logging and obtained the following: Created MBeanServer with ID: c3e82b:10179d228c6:-8000:XarqiMac.local:1 Jan 16, 2005 5:40:16 PM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on http-8080 Jan 16, 2005 5:40:16 PM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 4706 ms Jan 16, 2005 5:40:17 PM org.apache.catalina.core.StandardService start INFO: Starting service Catalina Jan 16, 2005 5:40:17 PM org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/5.5.4 Jan 16, 2005 5:40:17 PM org.apache.catalina.core.StandardHost start INFO: XML validation disabled Jan 16, 2005 5:40:22 PM org.apache.catalina.core.ApplicationContext log INFO: org.apache.webapp.balancer.BalancerFilter: init(): ruleChain: [org.apache.webapp.balancer.RuleChain: [org.apache.webapp.balancer.rules.URLStringMatchRule: Target string: News / Redirect URL: http://www.cnn.com], [org.apache.webapp.balancer.rules.RequestParameterRule: Target param name: paramName / Target param value: paramValue / Redirect URL: http://www.yahoo.com], [org.apache.webapp.balancer.rules.AcceptEverythingRule: Redirect URL: http://jakarta.apache.org]] Jan 16, 2005 5:40:23 PM org.apache.catalina.core.ApplicationContext log INFO: ContextListener: contextInitialized() Jan 16, 2005 5:40:23 PM org.apache.catalina.core.ApplicationContext log INFO: SessionListener: contextInitialized() Jan 16, 2005 5:40:24 PM org.apache.catalina.core.ApplicationContext log INFO: ContextListener: contextInitialized() Jan 16, 2005 5:40:24 PM org.apache.catalina.core.ApplicationContext log INFO: SessionListener: contextInitialized() Jan 16, 2005 5:40:25 PM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on http-8080 Jan 16, 2005 5:40:27 PM org.apache.jk.common.ChannelSocket init INFO: JK2: ajp13 listening on /0.0.0.0:8009 Jan 16, 2005 5:40:27 PM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=0/77 config=null Jan 16, 2005 5:40:27 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 10702 ms Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO: REQUEST URI =/hi/ Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO: authType=null Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO: characterEncoding=null Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO: contentLength=-1 Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO:contentType=null Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO:contextPath=/hi Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO: cookie=JSESSIONID=A1159716478A6F61B9760CCB58402392 Jan 16, 2005 5:40:28 PM org.apache.catalina.valves.RequestDumperValve invoke INFO: header=host=localhost:8080 J

I didn't do any setting up, other than to install the compatibility patch as directed. It is my understanding that this acts as a bridge between the "new" V5.5 tomcat architecture, and the old 1.4 JDK. From the success of the trial servlets, the installation seems to be working, and I just suspect that I have failed to configure something properly. Thanks for responding. (BTW, I didn't actually receive your response via email, but discovered it in an archive. I'm getting notification of other postings to the list, but not this one. Weird.

Just wanted to be sure as this has been the issue on several posts lately. Now for your problem. There are two (or more) ways that you can deploy an application. One is by manual file and folder creation and the other is by WAR files. Either way there is a directory structure that needs to be followed.

Still no success. This is what I have: $CATALINA_HOME/webapps/hi/WEB-INF/classes/hi.class $CATALINA_HOME/webapps/hi/WEB-INF/web.xml http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"; version="2.4"> Hello, World Application This is a simple web application with a source code organization based on the recommendations of the Application Developer's Guide. HelloServlet hi HelloServlet /h* $CATALINA_HOME/webapps/hi/META-INF/context.xml I've also tried it with the context.xml file renamed as hi.xml and placed in $CATALINA_HOME/conf/Catalina/localhost. When I use http://localhost:8080/hi, I get a tomcat generated page with a blank directory for "/".
