Subject: Urgent Re: Newbie: Servlet under Windows does not run
I am really desperate. I need to be able to demonstrate this servlet by
Tuesday evening and Tomcat still refuses to run it.
Essentially all that I have done is copy the examples from a book and change
the names to protect the innocent. The first few lines of the .java file
are:
package Census;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
public class CensusQuery extends HttpServlet {
I then compile this class and create the .war file with 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% CensusQuery.java | more
jar cf Census.war *.html WEB-INF
When the .war file is deployed by Tomcat the class file is located at:
D:\jakarta-tomcat-4.0.3\webapps\Census\WEB-INF\classes\Census\CensusQuery.cl
ass
All of this looks completely according to the documentation I have read.
What am I doing wrong so that Tomcat cannot find the class?

Basically, one machine will be serving a bunch of different hostnames from one IP address. For various reasons which I won't go into right now, it is an absolute impossibility to have separate IP addrs for these different machines, and also we can't configure them as virtual hosts in the server.xml file (trust me on this, it's an absolute impossibility). All the files that are served are in a few specific directories, like /statichtml, or /userhtml or whatever, which contain either static html or jsp pages. So here's what I did: I put this line in web.xml for the app: servlet-mapping servlet-name director /servlet-name url-pattern / /url-pattern /servlet-mapping I created a servlet called director.java, which would look at various parameters in the request, and then forwards it to the right place like this: RequestDispatcher rd = request.getRequestDispatcher(/staticpages/hello.html); rd.forward(request, response); or RequestDispatcher rd = request.getRequestDispatcher(/dynamic/hello.jsp); rd.forward(request, response); What happens is that when RequestDispatcher.forward() is called, it goes back through the mappings list, and sends the request straight back to director.java, which then looks at it and forwards it again, etc, in an endless loop. I understand what's going on, but is there a way to do it differently? I tried this also: RequestDispatcher rd = ServletContext.getNamedDispatcher(settings.corphtmlindex); but then I got this error: RequestDispatcher rd = ServletContext.getNamedDispatcher(/statichtml/hello.html); ^ director.java:159: non-static method getNamedDispatcher(java.lang.String) cannot be referenced from a static context I'm not sure what's going on here. One thought I had was this: in the mappings list, more specific mappings override less specific mappings, and / is the least specific mapping possible. Is there a way to put in mappings in web.xml to prevent the director servlet from being called? This seems like it would be a common thing to do under the MVC model, so there must be some solutions out there. Thanks

'Object Moved - 302' returned from https connection from a servle t
Hi, I'm trying to do a remote log on. I've tried a couple of sites, including www.bt.com. I do the Https connect using a POST.

JSP Naming Standards ?
Are there recognised naming standards for JSP's ? If I have a customer login page for Company ABC should I call it. ABC_Customer_Login or abc_cutomer_login or abccustomerlogin or abcCustomerLogin or what ? Please could you give me a reference to the standard, as I only want to change everything once ! Thanks David

How do I do an SSL handshake from a Java Servlet ?
I've got to write a java servlet to Login to a website which uses SSL. When you look at the web page that does the log on, the form uses a post. I create the url url = (URL) new URL(https://www.nxtrains.co.uk/NASApp/Neg/RoutingControl;); then set up a connection HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setRequestMethod(POST); conn.setDoOutput(true); conn.setDoInput(true); conn.setRequestProperty(Content-Length, +postData.length()); Then do the connect conn.connect(); OutputStreamWriter os = new OutputStreamWriter(conn.getOutputStream()); os.write(postData, 0, postData.length()); os.flush(); os.close(); But it isn't returning the screen which confirms the log on. Do I need to do an SSL handshake first, and if so what does it look like ? Thanks David
