Are you absolutely sure the problem is with CensusQuery and not a referenced class? It could be that Tomcat can't find another class that is referenced by CensusQuery, so it cannot load CensusQuery
Try stripping (or commenting) out all of the code except for a println call. This will show you if the servlet is actually being located or not. -----Original Message----- From: Jim Cobban [mailto:[EMAIL PROTECTED]] Sent: Monday, March 18, 2002 1:34 PM To: Tomcat Users List Subject: Re: Urgent Re: Newbie: Servlet under Windows does not run ----- Original Message ----- From: "Wagoner, Mark" <[EMAIL PROTECTED]> Subject: RE: Urgent Re: Newbie: Servlet under Windows does not run > What URL are you using to get to the servlet? I have tried a very wide range of URLs. According to all of the documentation the one that should work is http://localhost/servlet/Census.CensusQuery That is using the class name. However when that failed I also tried /servlet/Census/CensusQuery, and /servlet/CensusQuery. Since in my web.xml file, which I posted earlier, the name of the servlet, as opposed to the class, was Census1901 I also tried /servlet/Census1901. I have also tried using URL mapping specified in the WEB-INF/web.xml file. In any event the bottom lime is that when I request the above URL TomCat does go looking for my class. It just can't seem to find it! I know that I must be doing something wrong, because nobody else seems to be having any difficulty running servlets, but this is driving me crazy. I have been trying everything I can think of for more than a week and TomCat keeps claiming that it can't find the class. I have read the documentation over and over again. I have gone with a fine tooth comb through the examples trying to see what they are doing that is different from what I am doing. I just don't understand why this is so bloody difficulty. Just to put every bit of the documentation of this problem in one place: The first few lines of my servlet are: package Census; import java.io.*; import javax.servlet.*; import javax.servlet.http.*; import java.sql.*; public class CensusQuery extends HttpServlet { which I compile using the following .bat file: set PATH=C:\jdk1.3.1\bin;%PATH% set CP=D:\jakarta-tomcat-3.3a\lib\common\servlet.jar;WEB-INF\classes;%CLASSPATH% javac -d WEB-INF/classes -classpath %CP% ConnectionPool.java | more javac -d WEB-INF/classes -classpath %CP% DBResults.java | more javac -d WEB-INF/classes -classpath %CP% DriverUtilities.java | more javac -d WEB-INF/classes -classpath %CP% DatabaseUtilities.java | more javac -d WEB-INF/classes -classpath %CP% ServletUtilities.java | more javac -d WEB-INF/classes -classpath %CP% CensusQuery.java | more jar cf Census.war *.html WEB-INF The .war file this produces contains: D:\MyPrograms\JavaProgs\CensusServlet>jar -tf Census.war META-INF/ META-INF/MANIFEST.MF CensusQuery.html WEB-INF/ WEB-INF/classes/ WEB-INF/classes/Census/ WEB-INF/classes/Census/ConnectionPool.class WEB-INF/classes/Census/DBResults.class WEB-INF/classes/Census/DriverUtilities.class WEB-INF/classes/Census/DatabaseUtilities.class WEB-INF/classes/Census/ServletUtilities.class WEB-INF/classes/Census/CensusQuery.class WEB-INF/web.xml The web.xml file is: <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd";> <web-app> <display-name>My Web Application</display-name> <description> This is version X.X of an application to perform a wild and wonderful task, based on servlets and JSP pages.
