How do I change servlet contexts???
Tomcat: 4.1.24
I have a war file whose base context is /example.
Within that context there is an HTTP servlet
(GuestServlet) with a servlet mapping that captures
everything under /example/guest/*. Within
GuestServlet.class I create a RequestDispatcher to
forward control to an HTML page (lookup.html) under
the base context (/example). The problem is when
control is forwarded to /example/lookup.html it does
not work. The context remains unchanged at
/example/guest and so it actually attempts to display
/example/guest/lookup.html when I need
/example/lookup.html. I use the following code within
GuestServlet.java to try and display lookup.html under
the base context /example. Will someone please tell
me what I am doing wrong?
public class GuestServlet extends HttpServlet {
...
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
...
RequestDispatcher rd = null;
// Dispatch to next url
ServletContext cntxt =
context.getContext(/example);
rd = cntxt.getRequestDispatcher(/lookup.html);
rd.forward(request, response);
...
}
...
}

Where is mod_jk2?
Maybe I overlooked something, but I cannot find a link to download mod_jk2 (or coyote) for Apache 1.3.27 to talk with Tomcat at the jk2 website (http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/index.html). Does anyone know where the link to download mod_jk2 is? I find it incredible that there is no link to download jk2 at the jk2 website. There is only a link for mod_jk. TIA. __ Do you Yahoo!? Yahoo!

Re: Tomcat vs. JBoss
It is sad really to be exposed like this. Your company's web site does present you as the J2EE expert and yet you ask questions that do not mix, for lack of a better description. If you truly understood J2EE and merely glanced at the JBoss web site (www.jboss.org) you would hopefully be able to ascertain that JBoss functions primarily as an EJB container, while Tomcat can actually work with JBoss as its servlet container. Perhaps I am being a bit too harsh and should recognize that maybe its your mastery of the English language that is at fault here and you really do understand the differences between JBoss and Tomcat and simply did not pose the question clearly. If that is the case I apologize, but please be careful in presenting future questions otherwise I would anticipate plenty more grief from others. Finally, to answer your questions as best as I can interpret them. You are absolutely correct in that JBoss is complex. Hell, most production level J2EE servers (BEA Weblogic, IBM Websphere, etc.) are complex, probably due to the J2EE specification being a bit involved. But, as with all things they become much simpler with experience. As for Tomcat being a J2EE engine, that is a bad characterization. Tomcat merely implements a piece (servlets) of the J2EE specification. Tomcat, last I checked, does not function as an EJB container and so you cannot really compare it to JBoss. Although, JBoss does come with its own servlet container (JBoss Web, formerly Jetty). To answer your overall question, you can keep Tomcat and use it synergistically with JBoss as many others have done and it seems to work well in production depending on how they are being used. I hope this helps. Thanks. --- Michael Maier [EMAIL PROTECTED] wrote: hi johannes! i took a look at your companies homepage and there i can find infos about you: *snip on* Mag. Ing.

Re: SUCCESSFUL Tomcat Install!

Re: Search engines and MVC--to clarify
Your question is not descriptive enough, which is the reason you were directed to the java.sun.com website. What you are asking makes no sense. You must elaborate more about what you are trying to accomplish. You have 2 websites implemented under the MVC design pattern. Okay, now what? You would like to have them indexed? Huh, what does that mean? Indexed how? Do you want your controller to access a database (index) of URL's to redirect the user to the appropriate view or is it something else? Your inquired about search engines and their handling of the MVC design pattern. Well, search engines do not handle MVC. A developer can decide to use an MVC architecture and build their search engine into it to possibly function as part of the controller part of the paradigm. The way your question is worded it does not seem as if there is a clear understanding of what MVC is, nevermind the fact that it was mistaken for multi-view-controller. Unless, of course, I am totally mistaken, for which I would apologize, and that MVC has a second meaning. I would suggest that you either visit the site to understand more about the MVC design pattern or elaborate more on what you are trying to accomplish. I hope this helps.

Re: NEWBIE: Intercepting the jsp request before its written as a java file
If I understand your question correctly, why don't you
just use one of the include directives to insert that
into your file where you want it?
Either:
%@ include file=relativeURL %
-- OR --
jsp:include page={relativeURL | %= expression %}
flush=true| false
jsp:param name=parameterName
value={parameterValue | %= expression %} /+
/jsp:include

I would appreciate any help that you can provide in

Re: Digested Passwords and the server/lib/catalina.jar file
It's error prone either way-- .../common/lib or .../WEB-INF/lib-- upon upgrade. Without understanding the full scope of your project I would tend to lean towards the first solution (.../WEB-INF/lib) unless the .jar file needs to be available to all web applications. The common directory according to Jakarta-Tomcat is: Common - This class loader contains additional classes that are made visible to both Tomcat internal classes and to all web applications Moving a Tomcat server .jar file does not seem like a comfortable option-- it is like moving system libraries the OS depends on to a shareable area because you do not like them where they currently are located-- but if it works and you feel comfortable with it then use it.

I need to programatically digest passwords entered into the application for storage in the users table (when a new user is created or password changed). In the Digested Passwords section of the Realm HOWTO (Tomcat 4.1.10) there is a description of using the static Digest(). In order to use this method then I must, and I quote To use either of the above techniques, the $CATALINA_HOME/server/lib/catalina.jar file will need to be on your class path to make the RealmBase class available. There are a few ways to do this. I could copy the catalina.jar file to my web application WEB-INF/lib directory. Or, I could copy the catalina.jar file to $CATALINA_HOME/common/lib. I don't like the first method as it is error prone when I move to the next version of Tomcat (and forget to replace the cataline.jar file). So I'll probably go with the second method and copy the .jar file to the common/lib directory. Should I move the file instead of copying it? Could I create a symbolic link instead of copying?

Best Connector Setup???

In a production environment with Tomcat 4, which connector setup (HTTP, WARP, AJP) is best regarding performance and security??? Will one connector setup be better than another in a J2EE environment (OpenEJB, OC4J for the EJB containers)??? Should the Realm / element be used for authentication or is there a better method???
