HTTP Status 404

[kjell-einar]

I'm new to JBoss..., hope someone will guide me!!!

I have deployed TassieOnline.ear (from myEclipse).
I has some EJB's (..deploy/TassieOnline.ear/TassieOnlineEJB.war) pluss some servlets (deploy/TassieOnline.ear/TassieOnlineWeb.war).

The book I'm studying says I can access the servlet via this URL:
http://localhost:8080/servlet/ServletName

Have also tried
* http://localhost:8080/TassieOnline/...
* http://localhost:8080/TassieOnlineWeb/...
and various combinations with and without .../servlet/ServletName

The result is always the same, HTTP status 404 (the requested resource is not available).

What should I do?

Do you have a jboss-web.xml in your WAR file or application.xml in EAR file? If so, can you provide them, as well as your web.xml file? That could help.

This is
..deploy/TassieOnline.ear/META-INF/application.xml
------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<applicationxmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd" >
<display-name>TassieOnline</display-name>


<web-uri>TassieOnlineWeb.war</web-uri>
<context-root>/TassieOnlineWeb</context-root>



TassieOnlineEJB.jar


-----------------------------------------
Here follows
deploy/TassieOnline.ear/TassieOnlineWeb.war/WEB-INF/web.xml:

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

Tassie Online Book Store -- Example application


<servlet-name>SearchServlet</servlet-name>
<servlet-class>

</servlet-class>

</web-app>

I should also mention that according to the log-file this application is loaded without any error:

Any ideas?

I think I know the problem you have and the solution to it: you have to define the servlet-mapping element on your web.xml file after the servlet element declaration. It can be something like:

<servlet-mapping>
 <servlet-name>SearchServlet</servlet-name>
 <url-pattern>/Search</url-pattern>
</servlet-mapping>

There are two reasons you have to add this:
- The first one is that with the servlet element you just declare the servlet for being deployed in the webapp, but with the servlet-mapping you associate an URL to your servlet, so "everyone" can access it.
- What is said in your book about accessing "anonymous" servlets (that is, servlets without mappings) using the URL "/servlet/ServletClass" is correct, but due to security reasons, almost on every web container (like Tomcat) this behaviour is disabled.
Well, after that explanation only rests to explain you the URL you have to use to access that servlet. If you use the mapping I wrote, it would be "http://localhost:8080/TassieOnlineWeb/Search". This URL is composed first of your webapp context-root (defined in application.xml) which is TassieOnlineWeb, and then the servlet-mapping name you used in the web.xml file (in the example above, "/Search").
Hope my explanations helps you in understanding the error you have.
