Re: TC 4.0 newbie - servlet app won't run
Have you taken a look at the global web.xml file? It's located in $CATALINA_BASE/conf and contains some default mappings. One of those I believe takes care of finding HelloWorldExample.class for the examples context. At any rate you might find it an interesting read as these settings are available to all the apps. --David On Monday 26 November 2001 01:02 pm, you wrote: The examples you mentioned are the JSPs examples.

I will reply, Mark, in bits and drabs, as I try to figure out what you are missing and what you may have wrong. First, the servlets I referred to are not any different as servlets. They are not compiled JSP pages. The are regular old servlets. Compiled JSP page servlets are kept in tomcat/work/.

Re: TC 4.0 newbie - servlet app won't run (correction)
I have not looked at the webapps/examples except incidentally, Mark, so I am not sure how the HelloWorldExample servlet is accessed. How you access a servlet and where the servlet is are very important in these contexts. Inside and outside WEB-INF are very different, for example. Inside WEB-INF is dark to the outside world and must be accessed differently than outside WEB-INF. There must, as it were, be a portal. I still have not received answers from my last questions, which I need to go forward in my attempt to see what you may be doing. Certain answers to those questions could resolve everything.

Re: TC 4.0 newbie - servlet app won't run
Mark, I don't have webapps/examples running, so I need to ask you another question. Is there a class file called HelloWorldExample.class in examples/servlets/?, i.e. examples/servlets/HelloWorldExample.class. From what I can tell about your remarks, there should be. I notice that the only reference to any HelloWorldExample.class in the whole example app is in that file.

Let's look at a non-web.xml way. A.We can do it via URL by prepending the servlet's class name with /servlet/. Thus, we can access it as typically noted by http://localhost:8080/servlet/HelloWorld B.If the servlet if part of a package, then http://[serverroot]:8080/servlet/package.name.HelloWorld, where the servlet is put into server_root/webapps/yourapp/WEB-INF/classes/package/name Note that we have NOT MENTIONED THE web.xml. Okay? I think you are probably actually putting in the servlet reference as a directory or something. Are you? Are you including classes as part of a package name? Something like that must be going on. The directory classes is not part of the classpath. I assume you know that.

Re: TC 4.0 newbie - servlet app won't run
Your pattern does not occur in your post. So, the pattern will not send the post to the servlet. If you make your post anything and make your pattern anything, that will work. Get my drift? The post is just some text that should match the pattern and that will then refer the app to your servlet. -Original Message- From: Mark [EMAIL PROTECTED] To: [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Wednesday, November 21, 2001 12:39 PM Subject: TC 4.0 newbie - servlet app won't run I installed Tomcat 4.0.1 under Win 2k using JDK 1.3 and able to run the example servlets, but not my own.

Re: TC 4.0 newbie - servlet app won't run
Sorry, I'm not following you. What pattern are you referring to? Again, this app (and the html FORM/POST snippet I included) has worked under Forte and VAJ in the past. And I've looked at other Tomcat examples that look very much like what I'm doing, eg. http://www.onjava.com/pub/a/onjava/2001/04/19/tomcat.html At 01:15 PM 11/21/2001 -0800, you wrote: Your pattern does not occur in your post.

Re: TC 4.0 newbie - servlet app won't run
Mark, The servlet tag is used to assign a name to a particular servlet class file. servlet servlet-namemyservlet/servlet-name servlet-classmyservlet/servlet-class /servlet This would attempt to assign the name 'myservlet' to the class 'myservlet.class.'

Re: TC 4.0 newbie - servlet app won't run
Mark, Scott is right, of course, but there is no reason to use a url when in fact you are just using a tag or a name. It is misleading, in my opinion. In Scott's code, substituting form action=pudding method=post for form action=/servlet/servlet method=post works just as well as long as you use url-servletpudding/url-servlet instead of url-pattern/servlet/servlet/url-pattern. This is not an incidental matter. The latter for gives the mistaken impression that the semantics of url-pattern has something to do with urls, classpath, etc, which it does not. Once you free yourself of the meaningless references to urls in url-pattern you can begin to use it for passing code, keys for the controller servlet, etc. As long as you stick with url-look-alikes, you have misleading code. Typically, a Tomcat Model 2 Architecture uses this possible way of employing and passing free semantics to the controller. The issue, in my opinion, is not a trivial matter in Model 2 design patterns. -Original Message- From: Scott Ahten [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Date: Wednesday, November 21, 2001 9:20 PM Subject: Re: TC 4.0 newbie - servlet app won't runThi Mark, The servlet tag is used to assign a name to a particular servlet class file. servlet servlet-namemyservlet/servlet-name servlet-classmyservlet/servlet-class /servlet This would attempt to assign the name 'myservlet' to the class 'myservlet.class.'
