Running servlets not described in web.xml (tomcat-4.1.24)

Is it compulsory to have a entry in the web.xml to run a servlet in tomcat-4.x. In tomcat 3.x it was not required. If it is not a must how to enable that??
thanx in advance
Binny

i had completly forgotten i could just place a servlet in the web-inf/classes. after using jsp for so long, some things just get lost.
what im wondering now is if i can have other directories inside the classes directory and still be called while not being registered in the deployment descriptor ? in otherwords, lets say i have several servlets organized into packages. can i call a servlet thats in a particular package if i fully qualify the class ? guess ill have to try

Web.xml Tomcat 5.0 Servlet problem

Hey guys....
The last time I used a servlet was before the new change in security in Tomcat. Ive been looking all over the net for some easy references about how they are to be mapped but no matter what I try nothing seems to work.
My servlet is located in ROOT\Admin\WEB-INF\classes\colt and is called AddOLO.class
My web.xml file is located in ROOT\Admin\WEB-INF and contains the following code:
<servlet>
<servlet-name>AddOLO</servlet-name>
<servlet-class>colt.AddOLO</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>AddOLO</servlet-name>
<url-pattern>/Admin/add</url-pattern>
</servlet-mapping>
On the HTML form invoking the Servlet (addOLO.html) Im using the following small piece of code
<form action="http://Colt/Admin/servlet/AddOLO" method="post" align="centre">
The server is operating on Port 80.
All I seem to be getting is a 404 Error Saying The requested resource (/Admin/servlet/AddOLO) is not available. Can anyone see what is wrong here?
Thanks in advance

I don't think there's anything to prohibit you from deploying servlets in ROOT, but webapps that have pages and servlets that work together should be in their own context. That's what you did when you created the directory under webapps. I think it's the right way to deploy web apps. Even better, learn how to create and deploy WAR files:
http://access1.sun.com/techarticles/simple.WAR.html
Once you have a WAR, which is simply a JAR'd version of the directory you just created under webapps, you can simply pick it up and deploy it by dropping it into the webapps directory of any Tomcat server. Tomcat will unpack it for you. - MOD

Not specify servlet tag role-name - web.xml

          Hi all,
          I would like to know the servlet configuration in web.xml file. What is the difference
          between specification tag <role-name> and do not have tag <role-name> in web.xml
          file.
          Please advise me.
          Thanks and Best Regards,
          Kwanjai


difference          > between specification tag <role-name> and do not have
          > tag <role-name> in web.xml
          > file.
          <role-name> is usually used for security of a resource in a web application. This is generally used in conjunction with <security-role-ref> and <security-constraint> tag in the deployment descriptor.
          There are some docs on the BEA web-site on the same : http://e-docs.bea.com/wls/docs81/security/thin_client.html#1037337

Web.xml & Tomcat

hi
I have got tomcat5.0 running and am having trouble mapping my servlet so that it will run with the browser. Please tell me where I am going wrong. Java servlet test.HelloServlet compiles OK I have place the HelloServlet.class file in the following directory

Should be localhost:8080/trial/HelloServlet, you are forgetting the name of your web application in the url.

Web.xml - Tomcat vs iPlanet

I have a web application which was written using Forte with its built-in Tomcat engine. The application works fine in this environment.
I created a war file and put the application on our iPlanet server using wdeploy. I can open a JSP in the document root, but all of the servlets give the error "HTTP 404 - File not found".
Is there a difference in how the servlets must be referenced in the web.xml file for iPlanet vs Tomcat???

Weblogic7.0 requires that servlets be mapped to a
url:
<servlet-mapping>
<servlet-name>KioskServlet</servlet-name>
<url-pattern>/DriverKiosk.html</url-pattern>
</servlet-mapping>
I don't know specifically about websphere but I
suspect that may be the problem.The servlet was mapped to a URL.
The problem was that Forte did not require a leading slash, while iPlanet did require the slash:
Forte:
<url-pattern>myServlet</url-pattern>
iPlanet:
<url-pattern>/myServlet</url-pattern>

Using Servlet Parameters defined in web.xml

Hi all,
would like to use some of the properties of the UIX-Servlet within my UIX application (they may be configured in web.xml).
But how to get to the Servlet? Typically, one just gets a BajaContext which does not provide access to the servlet itself....
any ideas?
Thanx, Ernst.

Try these:
Servlet servlet = bajaContext.getService(Servlet.class, null);
ServletConfig config = bajaContext.getService(ServletConfig.class, null);

Catch the exception thrown when database is not available in web.xml

Hi,
I have an app that uses a mysql database configured in the web.xml configuration file - a javax.servlet.jsp.jstl.sql.dataSource param
There have been occasions where that server has been down, and this causes the expected error stack trace to be dumped to the jsp page
Is there anywhere I can catch that exception in the jsp page, so the end user does not see that nasty error?
Thanks,
Tom

You have answered your own question, catch the exception with a try catch block !!
try
// doing something stupid
catch (Exception exception)
out.println("sorry user, you did something really stupid");
// it is acceptable to do nothing here if you dont want to handle the
// error or output a message

Taglib element not allowed in web.xml conforming to web-app_2_4.xsd ?

Hello,
I want to configure taglibs in my web.xml file.
The beginning of the file looks like this:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<taglib>
    <taglib-uri>/tags/struts-bean</taglib-uri>
    <taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
</taglib>element just after the welcome-file-list element. When I "validate XML" in Netbeans I get :
cvc-complex-type.2.4.a: Invalid content was found starting with element 'taglib'. One of '{"http://java.sun.com/xml/ns/j2ee":description, "http://java.sun.com/xml/ns/j2ee":display-name, "http://java.sun.com/xml/ns/j2ee":icon, "http://java.sun.com/xml/ns/j2ee":distributable, "http://java.sun.com/xml/ns/j2ee":context-param, "http://java.sun.com/xml/ns/j2ee":filter, "http://java.sun.com/xml/ns/j2ee":filter-mapping, "http://java.sun.com/xml/ns/j2ee":listener, "http://java.sun.com/xml/ns/j2ee":servlet, "http://java.sun.com/xml/ns/j2ee":servlet-mapping, "http://java.sun.com/xml/ns/j2ee":session-config, "http://java.sun.com/xml/ns/j2ee":mime-mapping, "http://java.sun.com/xml/ns/j2ee":welcome-file-list, "http://java.sun.com/xml/ns/j2ee":error-page, "http://java.sun.com/xml/ns/j2ee":jsp-config, "http://java.sun.com/xml/ns/j2ee":security-constraint, "http://java.sun.com/xml/ns/j2ee":login-config, "http://java.sun.com/xml/ns/j2ee":security-role, "http://java.sun.com/xml/ns/j2ee":env-entry, "http://java.sun.com/xml/ns/j2ee":ejb-ref, "http://java.sun.com/xml/ns/j2ee":ejb-local-ref, "http://java.sun.com/xml/ns/j2ee":service-ref, "http://java.sun.com/xml/ns/j2ee":resource-ref, "http://java.sun.com/xml/ns/j2ee":resource-env-ref, "http://java.sun.com/xml/ns/j2ee":message-destination-ref, "http://java.sun.com/xml/ns/j2ee":message-destination, "http://java.sun.com/xml/ns/j2ee":locale-encoding-mapping-list}' is expected. [53]
cvc-complex-type.2.3: Element 'web-app' cannot have character [children], because the type's content type is element-only. [71]
XML validation finished.Indeed, looking at the web-app_2_4.xsd I cannot find a description for the taglib element.
Where should a put taglibs ? Is it enough to include them in every JSP so I don't need to place them in web.xml ?
Thank you.
Vlad.

web.xml 2.4 uses a <jsp-config> to enclose the
<tag-lib>
<jsp-config>
<tag-lib>
</tag-lib>
</jsp-config>I believe that is the syntax. I will check when I get
to my server comp.You are right. That's how it's done. Thanks a lot for the reply.
I hope there were good reasons to break compatibility with the old format. There are a lot of examples out there that use the old one. Without knowing the reason for such a change, I find it very annoying.
Thanks again

How to run servlets n sun one web server 6.1

Unable to run servlets on IWS 6.1

I would like to use "anonymous servlets" (i.e. servlets not defined in web.xml file or in a war file) on IWS 6.1
I could run servlets in this fashion on IWS 4.1 ve 6.0, however when I migrated my test server to IWS 6.1 I see servlet directory mappings are not present in this version of Iplanet, therefore my existing servlets did not run.
Does anybody know how to use servlet in anonymous fashion? My servlets are in /servlet directory of server root.

Right,
I have now created a new SSID (e.g. GUEST2) for which I have set to use WPA, under express security I can see broadcast enabled for both SSID's, however this second ID cannot be seen by any of my devices. I have ticked the "Multiple BSSID Beacon" as Set SSID as Guest Mode.
Nothing happens when I try to click the radio button "Multiple BSSID" for the two Radio's.
Many thanks

Can i run a servlet without a web.xml file for servlet mapping?

Hello everyone.
The code i want to run compiles and everythink looks ok.
It produces the .class file.
I run Tomcat 4.1 and i build my Web site with Dreamweaver.
I have a form in a page and i want to send the data upon form completion to a database i already have build with MySql.
The database is up and running and the server is set-up ok.
I have changed the port in Tomcat to run on port 80.
The directory i have my site is
Tomcat41\webapps\ROOT\se
and the directory where i keep the servlet class is
Tomcat41\webapps\ROOT\se\WEB-INF\servlet
I have a web.xml file to map the servlet and placed it in
Tomcat41\webapps\ROOT\se\WEB-INF
In the Form action i write action:"/servlets/Classes/GroupRegistration"
and I RECEIVE AN 404 ERROR FROM APACHE.

Thanks for any help.

and the directory where i keep the servlet class is
Tomcat41\webapps\ROOT\se\WEB-INF\servletOthers have pointed out that "servlet" should be "classes", but there is another mistake that hasn't been spotted. If you want your servlet to appear in the root context, you should use:
Tomcat41\webapps\ROOT\WEB-INF\classes
If you want your servlet to appear under the /se context, then you should use:
Tomcat41\webapps\se\WEB-INF\classes
and also, in the latter case, your form action should be /se/myGroupRegistration.

          It seems the weblogic.servlet.reloadCheckSecs property is not taking effect.
          The
          default value of -1 is always used. I did stop and restart weblogic.
          I also trid to set the servlet classpath in the web.xml file with
          weblogic.servlet.classpath
          property and it did not change the classpath for the servlet. It seems that
          other
          items are working such as adding new servletrs to the web application. Note
          that
          this is the cookie sample application that installes with the beta 2
          download.

Hi All:
Thanks for all your help regarding the adfAuthentication success_url. Now I am able to configure to make this work. But now I am facing another issue i.e. I am getting 401 Not authorized message when the success_url is pointed to the jspx page.
Note: I am using custom login module similar to DBProcOraDataSourceLoginModule so my roles are stored in the custom Role class. So I am not sure how to pass this role info to the security in ADF in order to authorize the page to be viewed.
Could you please help and can you point me to any specific link.
Thanks & Regards

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>

JDev 10.1.3 compile error in servlet 2.4 web.xml

I built a Servlet 2.4/JSP 2.0 application in JDev 10.1.3. When I try to make/compile/deploy it the compiler gives me errors like the following for every JSP file that has a JSTL 1.1 taglib:
Error(2,9): Element "web-app' used but not declared
Error(2,63): Attribute 'xmlns:xsi' used but not declared
Error(3,103): Attribute 'xsi:schemaLocation' used but not declared

Error(5,15): Element 'description used but not declared
It is obviously havng problems with the web.xml file (which is in the servlet 2.4 format) and is probably not finding the web.xml DTD document. How do I fix it?
