Web-inf\web.xml init parameters

Hi,
I use several servlets/JSPs which are using common init parameter, is there a way to specify that some init parameters are common or must I write all the parameters for all of my servlets/JPSs ?
Thanks

yah that's what I mean, have your parameters in your web.xml file and have a Servlet read them when the application starts up (using ServletConfig). Then you put the values into the application scope where all the JSPs and Servlets can read them. So lets say you specify a parameter called "html-path" with a value of "/www/html/" you could read this in your JSPs like this:
String htmlPath = application.getAttribute("html-path");I can't remember how to do his off-hand but I know it works.

JSF 1.2 web.xml configuration parameters

Actually, I know these JSF 1.2 web.xml configuration parameters:
javax.faces.CONFIG_FILES
javax.faces.DEFAULT_SUFFIX
javax.faces.LIFECYCLE_ID
javax.faces.STATE_SAVING_METHOD
Are there any more available?
(I have to study its performance implications in conjunction with RichFaces ones).

The JSF 1.2 specification document would contain the information you're looking for.

How to generate web.xml automatically?

Hi all!
I am new to servlets. I have configured the tomcat 5.5.9 with eclipse 3.0 succussfully. It is generating the class files. But I want to know how to generate web.xml through it.
Thanks in advance...
Code Snooker

AFAIK, there's no template for generating web.xml.
Navigate to <TomcatInstallDir>/webapps/
You would find lot of directories - each one being a web application.
Navigate to any one, say ROOT and then to the WEB-INF directory
under that.
You would find a web.xml.
Copy it into your <web-application-dir>/WEB-INF folder and make necessary changes

How should my web.xml be ?

Hi,
I have a servlet application. In my application, I make a call to my servlet through my index.html as follows:
<Form Action="/greeting/servlet/GreetingServlet" method="POST">
I also pass the values "name" and "email" through index.html
I have my servlet located at "D:\Amith\Servlet Applications\greeting\WEB-INF\classes"
I have added following lines in my server.xml
<Context path="/greeting" docBase="D:\Amith\Servlet Applications\greeting">
</Context>
The application runs fine with Tomcat 3.3.2 without web.xml
But when i try to run the application with Tomcat 5.0.24, I get the error
"HTTP Status 404 - /greeting/servlet/GreetingServlet"
Can anyone help me with this. Should i have web.xml for this. If yes, how should my web.xml be ?
Please help, I am unable to solve this problem from a very long time. I am really struck !!!
Thanks,
ammi

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

</servlet>
<servlet-mapping>
     <servlet-name>GreetingServlet</servlet-name>
     <url-pattern>/greeting/servlet/GreetingServlet</url-pattern>
</servlet-mapping>
</web-app>the servlet-class tag should contain the package where your servlet .class file is held. Just omit my one

How to Modify Server.xml and web.xml inTomcat

Hii
i am very new to tomcat..and using servlets..so plx tell me hw i can modify the server.xml and web.xml....
if my installables are in c:\program files\apache group\tomcat4.1
ok...i have my servlets file in c:\program files\apache group\tomcat4.1\webapps\ap1\WEB-INF\classes..so plz advice me on modifying the server.xml and web.xml....also tell me how and what we do in mapping
Plz tell me soon...
thanking u in advance.
rahul
Take care.:)

for web.xml you need something like this, i took this from the web.xml under the examples directory in tomcat:
<?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>
<servlet>
<servlet-name>
servletToJsp
</servlet-name>
<servlet-class>
servletToJsp
</servlet-class>
</servlet>
<servlet>
<servlet-name>
CompressionFilterTestServlet
</servlet-name>
<servlet-class>
compressionFilters.CompressionFilterTestServlet
</servlet-class>
</servlet>
</web-app>
basically you need to map the servlet with a class, for servlet-name call it whatever you like, you'll be using this name in the url to access you servlet, for the class give it the name of the class, java complied class, that's it.
server.xml is used to configure tomcat.

Modifying web.xml in Weblogic

Hi, I'm deploying an application written in JDeveloper 11.1.1.2.0 to Weblogic 10.3.2.
I'm trying to edit the web.xml file of the application. I tried to edit it here:
c:\Oracle\Middleware\user_projects\domains\uat_domain\servers\AdminServer\tmp\_WL_user\DrawingManagement\2ubcsw\war\WEB-INF\web.xml
However, any changes are not reflected in the application even though I have restarted Weblogic. However, when I change the values in JDeveloper and then deploy to Weblogic, the values are reflected in the web.xml defined above.
Is Weblogic caching this web.xml? If so, how do I modify it?
Edited by: Sean Ong on Aug 8, 2010 9:11 PM

Hi,
If you will try to edit the "web.xml" from the following Location: c:\Oracle\Middleware\user_projects\domains\uat_domain\servers\AdminServer\tmp\_WL_user\DrawingManagement\2ubcsw\war\WEB-INF\web.xml
Then it will not be reflected. Because as soon as you deploy your Application on WebLogic it Reads the "web.xml" *(At Deploy time Once)* and keeps it in Memory. So if you really want to change the Deployment descriptor then You will need to redeploy the Application after editing it inside your JDeveloper project it self.
Or as an alternative you can use the "plan.xml" feature of weblogic to change the DDs...like: http://forums.oracle.com/forums/thread.jspa?threadID=1107834&tstart=0

Dynamically modifying web.xml

Hi,
          I am trying to write code that will dynamically add a servlet definition to a deployed application. ie, the deployment descriptor is dynamically edited. In Tomcat, I am able to edit the web.xml file(when the app is exploded) or I can edit the in memory copy and produce a servlet definition on the fly
          I am trying to do the same of Weblogic 8.1. Everything is straightforward as long as the app is exploded, in which case I simply edit the web.xml file..when the app is not exploded, this is not possible. I tried using MBeans to see if I can add a servletRuntimeMBean to a deployed application, but this does not seem possible..looks like these beans are instantiated by the container and there is no handle for developers to create instances of these beans. I was wondering if it was possible to edit the in memory copy of web.xml that the servlet container records. Any suggestions in this regard would be highly welcome
          Thanks, and sorry for the lengthy email!

<taglib>
     <taglib-uri>/mytags</taglib-uri>
     <taglib-location>/mytags.tld</taglib-location>
</taglib>That means that your tag libaray definition is located at /root/mytags.tld. Some people put them in the WEB-INF, which would make it /root/WEB-INF/mytags.tld.
The taglib-uri is how you are going to reference it in your JSP. With the above setup, here is how you would reference in your JSP
<%@ taglib uri="/mytags" prefix="myTagPrefix" %>
<myTagPrefix:mySpecialTag/>
Hope this helps.

Modifying web.xml for a custom tag

Hello all, I'm trying to create a custom tag, and I'm having trouble trying to understand some elements of web.xml. Can someone tell me in detail what <taglib-uri> is? I know <taglib-location> is the directory where the .tld file is stored.
Also, is there anywhere online where I could find out more about the different compinents of web.xml? (I can't find any good websites).
Thanks a lot.

How to reupdate web.xml

          hi,
          I downloaded WLS 6.0, W2K for testing.
          Whenever I updated web.xml for my new servlets, I need to stop and restart weblogic
          server.
          Is there any way for weblogic to detect that web.xml had changed and updated accordingly
          or command line to trigger update in web.xml?
          thanks.
          - yoke


          An application or application component can be dynamically redeployed while the server is running. This may be useful if you want to update a deployed application or application component without stopping and restarting the WebLogic Administration Server. To dynamically redeploy a JAR, WAR or EAR file, simply copy the new version of the file over the existing file in the /applications directory.
          You can also dynamically redeploy applications or application components that have been deployed in exploded format. When an application has been deployed in exploded format, the Administration Server periodically looks for a file named REDEPLOY in the exploded application directory. If the timestamp on this file changes, the Administration Server redeploys the exploded directory.
          If you want to update files in an exploded application directory, do the following:
          1. When you first deploy the exploded application, create an empty file named REDEPLOY in the directory where the exploded application resides.
          2. To update the exploded application, copy the updated files over the existing files in that directory.
          3. After copying the new files, touch the REDEPLOY file in the exploded directory to alter its timestamp.
          When the Administration Server detects the changed timestamp, it redeploys the contents of the exploded directory.

How to edit web.xml deployment descriptor from console in weblogic 8.1?

In weblogic 7.0, deployment descriptor such as web.xml can be edited from the admin
console, but on weblogic 8.1 I can't find a way to do so.
Is this function taken out? Why is it taken out? Do I have an alternative to edit
it without unpacking and packing the EAR or WAR?
Thanks in advance.

Re: how to recover web.xml after editing by word?

Do you seriously think that there's a way to reconstruct the full XML from these tiny pieces of information? One can guess, but it builds down to re-writing the web.xml
Your best bet is to get the last version of that file from your [version control system|http://en.wikipedia.org/wiki/Revision_control]. You surely use one, right? And if you don't, then you now know why you should be using one.

Thanks. Fortunately I got a web.xml with similar format from other's folder.
It is terrible. All the tabs in web.xml are missing and changed into microsoft word's tabs. Be careful.We are. We would never ever ever use Word as a text editor and we use a version control system.
