Help: running servlets on IIS
Hello, I had a very simple question that I have been struggling with and any help on which I would greatly appreciate. I am trying to run servlets on IIS using tomcat below IIS. I have an external *.properties file that contains all the initial arguments for my servlet. Can anybody tell me how I can get this properties file loaded every time the servlet is invoked by the browser. I tried giving the properties name and file location in the web.xml file in the init param section but I still get an error message in the browser saying it did not find the file. I have tried both C:\jakarta-tomcat and, the partial \WEB-INF\ as the param value. I heard an other option is to extend init and load the file. Details regarding any of this will be greatly appreciated. I am new to most of this stuff Please help!!! Thanks. Raghu
Help with Servlets
I've spent DAYS and DAYS and DAYS trying to get tomcat to run servlets. Nothing I try works. I have followed the instructions in three books, several online tutorials and attempted to decipher tomcat documentation on the apache site. I've installed and reinstalled two versions to Tomcat (currently on 4.1.24). I've modified server.xml and web.xml files until my fingers are sore from typing. Any help would be GREATLY appreciated. Nothing helps; nothing works except the tomcat examples which mock me! Here is my problem: From a clean install of tomcat, create a new directory under webapps called dumfries. Create subdirectories dumfries/WEB-INF/classes. Copy the file HelloWorldExample.class from webapps/examples/WEB-INF/classes and paste it into webapps/dumfries/WEB-INF/classes Create the following file and save as web.xml in the webapps/dumfries/WEB-INF directory: ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/j2ee/dtds/web-app_2_3.dtd; servlet servlet-nameHelloWorldExample/servlet-name servlet-classHelloWorldExample/servlet-class /servlet web-app /web-app Add the following tag to the server.xml file: Context path=/dumfries docBase=dumfries debug=0 reloadable=true / Start the server and browse to http://localhost:8080/examples/servlet/HelloWorldExample; Note that the page displays. Now browse to http://localhost:8080/dumfries/servlet/HelloWorldExample; and behold the error message. What am I doing wrong How can I make this work??? I'm supposed to be half way done with my project and I can't get my first servlet to work!!! Help!

Re: Help with Servlets
At least you didn't say you've tried everything: I hate that, if you
have tried everything, something would have worked ;-),
but anyways, I'm going of on a tangent ...
Firstly, your web.xml looks kinda screwed: You have nothing mapped
int the wep app.
Then, quite likely your major problem is that you have not
mapped any requests to your servlet.
You need to map your web application to it's implementation. It's not
enough to just state your web descriptor {Like your post shows}, you
will also need something like
!-- Map requests to servlet --
servlet-mapping
servlet-nameServletName/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
after ALL the servlet / definitions.
So something like ...
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app
PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN
http://java.sun.com/dtd/web-app_2_3.dtd;
web-app
!-- Publish the servlet to the container --
servlet
servlet-nameYourServletName/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet
!-- Map requests to servlet --
servlet-mapping
servlet-nameYourServletName/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
/web-app
That's of course, assuming a few things ...
1. Your servlet is compiled, and a proper extension of HttpServlet
2. You want everything under
http://yourservername.domain/YourServletName to go to your servlet.
3. And probably another few things,
Hopefully this will help you in the right direction ...

If I have multiple servlets, do I need to publish all to the container

Re: Help with Servlets
Yes, you do need to provide a servlet mapping for each of your servlets you
wish to run, unless you want to run the invoker servlet (not recommended).
Usually you map a different url pattern for each servlet in your webapp.
This can be somewhat tedious, so I use XDoclet to generate my web.xml file
for me! But, for simple projects, this is not necessary.

Oh, yes the order matters how you define things in your web.xml file. It
has to follow the DTD.

Re: Help with Servlets
First, as a suggestion, you will need to understand XML and DTD's: This
will explain what the web.xml file can and can not do.
Then: There are multiple ways of doing servlet mappings: I tend to stay
away from war files, for no particular reason at all, so, in that case,
I need to map all my servlets and their requests in the web.xml file. I
have no experience with war files, but understand you do / can do it
differently using that.
web.xml
You need to publish every and all servlets, FIRST.
You need to map all the servlets to their requests, after publishing all
the servlets ...

Subject: Re: Help with Servlets
First, as a suggestion, you will need to understand XML and DTD's: This
will explain what the web.xml file can and can not do.
Then: There are multiple ways of doing servlet mappings: I tend to stay
away from war files, for no particular reason at all, so, in that case,
I need to map all my servlets and their requests in the web.xml file. I
have no experience with war files, but understand you do / can do it
differently using that.
web.xml
You need to publish every and all servlets, FIRST.
You need to map all the servlets to their requests, after publishing all
the servlets ...
web-app
!-- Publish the servlet to the container --
servlet
servlet-nameServlet1/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet
servlet
servlet-nameServlet2/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet
servlet
servlet-nameServlet3/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet
!-- Map requests to servlet --
servlet-mapping
servlet-nameServlet1/servlet-name
url-pattern/Servlet1/*/url-pattern
/servlet-mapping
servlet-mapping
servlet-nameServlet2/servlet-name
url-pattern/Servlet2/*/url-pattern
/servlet-mapping
servlet-mapping
servlet-nameServlet3/servlet-name
url-pattern/Servlet3/*/url-pattern
/servlet-mapping
/web-app
etc, ad infinitum ...
hth,

Thank you. I am seeing some success with this!
If I have multiple servlets, do I need to publish all to the container
individually and map each request to the servlet individually and does
the
order matter?
Thanks again...

Subject: Re: Help with Servlets
At least you didn't say you've tried everything: I hate that, if you
have tried everything, something would have worked ;-),
but anyways, I'm going of on a tangent ...
Firstly, your web.xml looks kinda screwed: You have nothing mapped
int the wep app.
Then, quite likely your major problem is that you have not
mapped any requests to your servlet.
You need to map your web application to it's implementation. It's not
enough to just state your web descriptor {Like your post shows}, you
will also need something like
!-- Map requests to servlet --
servlet-mapping
servlet-nameServletName/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
after ALL the servlet / definitions.
So something like ...
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app
PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN
http://java.sun.com/dtd/web-app_2_3.dtd;
web-app
!-- Publish the servlet to the container --
servlet
servlet-nameYourServletName/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet
!-- Map requests to servlet --
servlet-mapping
servlet-nameYourServletName/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
/web-app
That's of course, assuming a few things ...
1. Your servlet is compiled, and a proper extension of HttpServlet
2. You want everything under
http://yourservername.domain/YourServletName to go to your servlet.
3. And probably another few things,
Hopefully this will help you in the right direction ...

I've spent DAYS and DAYS and DAYS trying to get tomcat to run
servlets.
Nothing I try works. I have followed the instructions in three books,
several online tutorials and attempted to decipher tomcat documentation
on
the apache site. I've installed and reinstalled two versions to Tomcat
(currently on 4.1.24). I've modified server.xml and web.xml files until
my
fingers are sore from typing. Any help would be GREATLY appreciated.
Nothing
helps; nothing works except the tomcat examples which mock me!
Here is my problem:
From a clean install of tomcat, create a new directory under
webapps
called dumfries. Create subdirectories dumfries/WEB-INF/classes.
Copy the file HelloWorldExample.class from
webapps/examples/WEB-INF/classes and paste it into
webapps/dumfries/WEB-INF/classes
Create the following file and save as web.xml in the
webapps/dumfries/WEB-INF directory:
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app
