Do we need to put the following code in the web-xml for the project to run

Hi^^^,
actually I have created a project in Eclipse WTP and I am running it from remote server. Its giving me 404 error when I tried to run it.
I know 404 error is generally due to some error in deployment descriptor.
I am going through this tutorial for creating project in eclipse WTP
this says that I need to include the following code in web-xml. Please look at the quotes below
"Web modules in J2EE has a deployment descriptor where you configure the web application and its components. This deployment descriptors is called the web.xml. According to the J2EE specification, it must be located in the WEB-INF folder. web.xml must have definitions for the Servlet and the Servlet URI mapping. Enter the following lines into web.xml:"
"Listing 2. Deployment Descriptor web.xml"
<servlet>
<servlet-name>Snoop Servlet</servlet-name>
<servlet-class>org.eclipse.wtp.tutorial.SnoopServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Snoop Servlet</servlet-name>
<url-pattern>/snoop/*</url-pattern>
</servlet-mapping>
My question is, it is necessary to include the above lines between <servlet> and </servlet-mapping> in web-xml
thanks and regards,
Prashant

<servlet>
<servlet-name>Snoop Servlet</servlet-name>
<servlet-class>org.eclipse.wtp.tutorial.SnoopServlet</servlet-class>
</servlet> Every Servlet has to have a <servlet></Servlet> tag in the web.xml
the <servlet-name>is for the naming the servlet and the <servlet-calss>is for class file of the servlet in your case the .class file is to be in the package of tutorial,if it's not then how the container will no where the calss file is
<servlet-mapping>
<servlet-name>Snoop Servlet</servlet-name>
<url-pattern>/snoop/*</url-pattern>
</servlet-mapping>You type something in your url likk http://localhost:8080/webappname (Tomcat server),so for url mapping instead of typing the entire class file name ,you just enough have to type what you've put in the <url-mapping> tag and it has to be inside of <servlet-mapping>
I think the problem is in <url-pattern> change it like /snoop<url-pattern>
My question is, it is necessary to include the above lines between <servlet> and ></servlet->mapping> in web.xmlSo now you think whether you need something inside <servlet>and </servlet-mapping>

How to configure a JNDI ressource in the web.xml file

Hi,
does someone know if there is a way to configure a JNDI ressource with its parameters only in the web.xml file ?
In my case, the JNDI ressouce is an oracle database an its conenction paramters: driverClassName, username, password, etc...
Actually, I put everything in the configuration file of Tomcat but I would like my war file to be 100% independent of the application server.
Thanks in advance.
Fred.

I wrestled with this for a long time. I may have done something wrong, but to get my mySQL JDNI reference to work, I had to add it to the server.xml file. You can try with web.xml, but I eventually just got frustrated and put it in server.xml.
The following is between two <context> tags:
<Resource name="jdbc/instance_name_goes_here"
               auth="Container"
               type="javax.sql.DataSource"/>
          <ResourceParams name="jdbc/same_instance_name_here">
               <parameter>
                    <name>username</name>
                    <value>user_name_goes_here</value>
               </parameter>
               <parameter>
                    <name>password</name>
                    <value>password_goes_here</value>
               </parameter>
               <parameter>

How do you modify the web.xml to lock down the pages from a user role

how do you modify the web.xml to lock down the pages from a user role

I'll make a stab at your question:
The following is an example of where a URL is protected within a web.xml deployment descriptor. In this example, the URL /protectedA within the application is protected:

<security-constraint>
<web-resource-collection>
<web-resource-name>protectedA</web-resource-name>
<url-pattern>/protectedA</url-pattern>
</web-resource-collection>

<auth-constraint>
<role-name>sr_developer</role-name>
</auth-constraint>
</security-constraint>

JSP compiler reading the web.xml file?

Hi,
          I am trying to use the weblogic JSP compiler (weblogic.jspc) to
          pre-compile some JSP that use custom tags. Does the compiler
          read the web.xml file if there is one? In particular the taglib
          elements in that file so that the compiler understands the
          <%@ taglib ... %> directive.
          In the JSP I try to compile I use this statement to declare a taglib:
          <%@ taglib uri="xyz/xyz-taglib" prefix="xyz" %>
          and in my web.xml I have:
          <taglib>
          <taglib-uri>xyz/xyz-taglib</taglib-uri>
          <taglib-location>/WEB-INF/tlds/xyz.tld</taglib-location>
          </taglib>
          When I try to compile the JSP I get the following error:
          Could not parse embedded JSP code: weblogic.utils.ParsingException: nested
          IOException: java.io.IOException: cannot resolve 'xyz/xyz-taglib' into a
          valid tag library.
          Any ideas how I can resolve this?
          In advance thank you for any help.

I'm pretty sure you can't do it that way round. The logic of the thing is that database access URLs etc. tend to depend on the where the server is. The whole idea of these resources is to put the stuff that's specific to the server in server.xml and refer to it using names that should remain the same if you deploy your webapp on another server. Of, for example, you have test, stage and production servers running the same webapps but connecting to different databases.

Whats the purpose of the web.xml file?

Hi
What is the purpose of the web.xml fle?
and does it have any impact on deployment?
I get this msg when I am compiling .
ignoring C:\JDeveloper9iRC\jdev\mywork\MIS_IntranetWS\mis_intranet\public_html\WEB-INF\web.xml; not on sourcepath
I cannot deploy but for what reason I don't know. Am wondering if this is related at all
Thanks

The web.xml file is the standard deployment descriptor for a J2EE web application (or "web module" when it is part of a J2EE Application). The full details of what the web.xml is for is described in the Servlet 2.2 spec (if you're using J2EE 1.2) or the Servlet 2.3 spec (if you're using J2EE 1.3). You can download the Servlet spec from http://java.sun.com/products/servlet/download.html
The web.xml file is used when deploying a WAR file to a J2EE app server. However the message you cite isn't indicating a deployment failure. When you get a deployment failure, you should see a message in the JDev Log Window indicating the reason for the failure. Be sure the Log Window is visible by selecting View | Log Window from the main menu.

Trouble adding alias to the web.xml file (External Facing Portal)

I'm trying to implement the external facing portal. I don't really have any real custom content to add to it but have just created an iView that contains a webpage that's contained within a copy of the light framework.
I'm having trouble adding or accessing the alias that I've created to go to this iView.
I can test my iView by adding it to the master rule collection under one of the predefined aliases in the web.xml (e.g. portal/anonymous etc) but when i define my own (e.g. "ext" etc) and then go to http://portal:<port>/irj/ext I'm just getting an error:
The requested resource does not exist.
Details:   Go to main page of this application!
This is what my entry in the web.xml file looks like:
<web-app>
<display-name>The Java iView Runtime</display-name>
<listener>
<listener-class>
com.sapportals.portal.prt.session.HttpSessionHandler
</listener-class>
</listener>
<servlet>
<servlet>
<init-param>
   <param-name>
      portal/anonymous
   </param-name>
   <param-value>
anonymous=1,proxy=0,low_bandwidth=0,include_in_url=1,include_application_name_in_url=1
   </param-value>
</init-param>
<init-param>
<param-name>
   ext
</param-name>
<param-value>
anonymous=1,proxy=0,low_bandwidth=1,include_in_url=1,include_application_name_in_url=1
</param-value>
<init-param>
</servlet>
My master rule collection seems to be correct, since I can test the iView etc by adding it to a predefined alias. I've tried closing all browsers etc. Nothing seems to work.
Any ideas what this could be?
Thanks!
I'll award points for any help.

Hi Beau
Just Have a try.
In the servlet mapping add the following entry.
<servlet-mapping>
<servlet-name> gateway </servlet-name>
<url-pattern> /portal/* </url-pattern>
</servlet-mapping>
<b><servlet-mapping>
<servlet-name> gateway </servlet-name>
<url-pattern> /ext/* </url-pattern>
</servlet-mapping></b>
<servlet-mapping>
<servlet-name> prt </servlet-name>
<url-pattern> /irj/* </url-pattern>
</servlet-mapping>
Restart after making the changes.

How to avoid inserting CheckSessionFilter in to the web.xml file?

Mobile Server modifies the web.xml during adding a .war-file to the publication. A new entry- CheckSessionFilter will be inserted inside the web.xml after uploading to the mobile server:
****************** inserted part **********************
<filter>
<filter-name>CheckSessionFilter</filter-name>
<filter-class>oracle.lite.web.CheckSessionFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CheckSessionFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
****************** inserted part **********************
Our application has own security-concept and don’t need this additional session checking.
How can we avoid including of CheckSessionFilter in to our web.xml?

Don't do "add a war option" Instead, package your application using packaging wizard omitting the filter. Or, you can edit the WEB-INF/web.xml file on the mobile server after you deploy it.
Make you update the APPLICATIONS table
UPDATE APPLICATIONS
SET PUBLISH_TIME = SYSDATE
WHERE NAME = 'you application';
You application will be uploaded to:
STANDALONE
ORACLE_HOME/mobile_oc4j/j2ee/application/mobileserver/applications/yourapplication/WEB-INF/web.xml
IAS
ORACLE_HOME/j2ee/application/mobileserver/applications/yourapplication/WEB-INF/web.xml

How to deploy the web.xml file when trying to use the JSP SDK from SAP?

I want to use the adduser.jsp which downloaded form SAP SDK samples to add user in BO, but I cannot run it sucessfully. I believe it's caused the web.xml file was not deployed appropriately.
could you please teach how to deploy the web.xml file for the JSP samples ?
Could you show me some sample of web.xml for the SDK jsp files? Thank you very much!

Ensure that you have followed below directory structure while deploying your web application.
   web_application_name
      WEB-INF
         lib
         classes
web.xml must be placed in WEB-INF. Ensure that you have included all the jar files and other necessary files in your application.
