Servlet cannot be preloaded given web.xml is defined in Weblogic 10.3...

My web.xml loads on startup first before getting any request to initialise attributes in servlet by fetching from properties file. In Weblogic 8.1 it works fine but not in Weblogic 10.3 while setting attribute its getting null values and throws error in another jsp page.
The actual error is like :
[HTTP:101216]Servlet: "bbbbb" failed to preload on startup in Web application: "aaaaa.war". javax.servlet.ServletException: Error in Log4j File at com.z.y.bbbbb.init(bbbbb.java:49)
Log4j in 10.3 are by default. I changed the configuration from default to Log4j. The application loads successfully if I do vice versa the application fails. If i delete the line load on startup from web.xml the application starts successfully.
Any idea to deal with this situation?
Thanks.
I guess this is new kind of error which very less have came across but it will be a lesson learnt if someone could throw some light as to why such errors are resulted and how it can be prevented.
Thanks a bunch!

Hello, Any idea whats goin on?
Edited by: jennifer123 on Aug 12, 2009 1:37 PM

Contact the Weblogic guys. This problem is unrelated to Servlet API.
All I can do here is to suggest you to get rid of the buggy Weblogic appserver and go for a more robust implementation. For example Tomcat or one of its clones or Glassfish.

Calling servlet with out entry in web.xml

Hi
I want to know whether can a servlet be invoked with out having an entry in web.xml.Because to my knowledge when ever an entry is made in teh web.xml the <url-pattern> and the class file will be stored as key value combination it is only then when ever a request is made the server gets the class taht is to be invoked from the <url-pattern> that is passed from the client side.
Is ther any way by whihc we can call the servlet directly with out an entry in web.xml
Thanks in advance

Interesting that it is possible on Tomcat anyway.
What's the real benefit of not having a Servlet
definied in web.xml?
The only benefit I see is that
you don't need to understand/read/change XML when
adding or removing a servlet. That isn't worth that
imho. What are the other benefits?The only thing I can think of is , to be able to quickly access a Servlet that you've just written, because it takes additional steps to define it in the web.xml.
I think it would be a security concern (of some sort) , if the Servlet's class is known, that's why it is better to access a Servlet with a mapping from web.xml

What if i give -1 as a Servlet instance in pool in web.xml

What if i give -1 as a no of Servlet instance, in pool, in web.xml

Try it and them get back to us and let us know if it works.

What is web.xml and why it is used?

hi,
am new to servlet technology, i tried to find a topic like this in this fourm also in google but didn't get a exact one. can anybody explain me or suggest me some resource about this.
thanx in advance.

hi stevejluke,
thanx for the correct link.
nx for the correct link. but what i in doubt with is
why we should use web.xml? may be my question is very
silly, may be too basic, forgive me for that...
Thanx & Regards,
SaikatAt the most basic level:
There are several versions of the Servlet specification, You need the web.xml to tell the server which version of the spec your application conforms to so the server knows how to deal with different things.
If you have a servlet, you also need the web.xml to define what URL signals a request that should be handled by your servlet.
At this point, you need to sit down and read a book. Do what it says, blindly at first. Just do what it says (but do try to understand the 'what' of it, just don't question the 'why'). After you have a few applications running, go back and ask yourself this question again and try to see what you are using the web.xml for in those applications you have.

Registered servlets in web.xml do not work....WHY????

Hi i am executing a web application on tomcat 4.1.29 and have the following structure...the jsp pages are executed but when sendinga request to a servlet the servlets are not executed...Can somebody guide me out of this....
webapps
{MyApp}->[web-inf][jsp]
{web-inf}->[classes][lib]
{classes}->[com][src]
{src}->[source files]
when the source files are compiled package structure is followed and the class files are grneated in
com.MyApp.servlets
...etc
the servlets are registered in the web.xml file as shown below.....few lines of my web.xml file
<servlet>
<servlet-name>userServlet</servlet-name>
<servlet-class>com.MyApp.servlets.UserServlet</servlet-class>
</servlet>
even then when accessing a servlet it says the resource not found
The requested resource (/MyApp/servlet/UserServlet) is not available.
am i missing something some where...why are the servlets not executed????

    <servlet>
        <servlet-name>UserServlet</servlet-name>
        <servlet-class>com.MyApp.servlets.UserServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>UserServlet</servlet-name>
        <url-pattern>/User</url-pattern>
    </servlet-mapping>I'd invoke it with this URL:
http://localhost:8080/MyApp/UserServlet
hmm something seems to be wrong here ;-)
URL should be
http://localhost:8080/MyApp/User (see <url-pattern>)

Processing web.xml -Adding servlet

Can you please give me an out line how to add servlets/filters/session-configs to web.xml programatically.
I have writen a program for adding these but In web.xml the order in which elements are placed matters. So right now in the program I specify that I should add this element before another specified element like that .
How can we make this generic ? I mean how I can maintain the same order as of DTD ?
please help me.

Answering your original question. Yes it is possible to have a web.xml without servlet classes, if you are not using servlet classes.

MalaiIt looks like there may be BOM characters (invisible in regular editors), before the opening angle bracket of the XML prolog: <?xml version="1.0"
The special characters usually are inserted by some editors such as Notepad.
You can download a free Hex editor, like Cygnus hex editor and see if you have the 3 special characters (in Hex) appearing before the XML prolog.
If you see anything before the prolog delete them, save the web.xml file and re-test it.

Odd message about web.xml

I'm getting this message on the console of the WL9.0 Admin server when
it starts up:

Question: does it work?
From my understanding this is not what you should do. The Welcome page is used when no specific page of the application is given in the url. It can either be a jspx page or a html page. A task flow may contain a page, but is not a page. From this definition I conclude that you should not do this.
One other reason is that is you use security you secure a task flow (as a whole resource) and the welcome page is the entry point giving the use the ability to log in (so it is not secured). The welcome page might also be the landing page after a logout.

What is Wrong with my filter and filter-mapping in web.xml?

First, thanks all for your attention.
I have checked the place where I should place <filter> and <filter-mapping> in web.xm. They should be after the <display-name>, before <servlet> and <servlet-mapping>.
However, as soon as I insert the <filter> and <filter-mapping> elements in my web.xml, all my struts-bean.tld, struts-html.tld, etc. in the web.xml cannot be found at the runtime.
Please help in identifying the problem. Thank you.

Filters were introduced in the servlet 2.3 specification (j2ee 1.3) - http://java.sun.com/products/servlet/Filters.html.
Your web.xml constraints your web application to adhere to 2.2 standards (according to your DOCTYPE definition in your web.xml). Change it to conform to 2.3 standards
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

You must declare TestServCon.java on web.xml as you did for the first servlet
and in the sendRedirect use the following code :
response.sendRedirect("TestServCon");//   TestServCon is the servlet mapping you declared in web.xml
//or this
response.sendRedirect("./TestServCon");

Add virtual directory to orion-web.xml file of embedded OC4J instance

I'd like to add a virtual directory to the orion-web.xml file of the embedded OC4J application which comes with JDeveloper (version 10.1.3.3.0.4157). Every time I run my application however, a new orion-web.xml file is created which overwrites the orion-web.xml file with my virtual directory. The orion-web.xml is located in the <JDev_Home>\jdev\system\oracle.j2ee.10.1.3.41.57\embedded-oc4j\application-deployments\current-workspace-app\<app Name> directory.
Does anybody know a solution to this problem?
Regards,
Matthieu

hi there,
i have the same problem, all the configuration files are included in the EAR file, like application.xml,...
but the orion-web.xml is not included.
I dont have that option that you mencioned File->New->Deployment Descriptiors -> web...for oc4j...
I can create a EAR, WAR or JAR in File->New->Deployment Profiles.
I need the orion-web.xml to define the MIME types the servlet can return, is it really needed?

Laura

Problem with web.xml

Hello,
I have a big problem with web.xml.
i can run the servlet demos with the default web.xml, but when i try to user a costum web.xml files, i receive a 404 page not found on a link.
i have some dificulty to post here. but can somebody help my with my web.xml files?
thanks for your help.
have a nice day!

Be careful with the place of your files and folders. It's possible that you've just mentioned the cause of your problem.
My web.xml is
<?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>
<display-name>gco</display-name>
<description>gco webapplicaties</description>
<servlet>
<servlet-name>MopoController</servlet-name>
<servlet-class>org.gertcuppens.controller.MopoController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MopoController</servlet-name>
<url-pattern>/MOPO</url-pattern>
</servlet-mapping>
</web-app>
When I want to call my web application locally, I use the URL http://localhost:8080/gco/MOPO.
The http://localhost:8080 calls Tomcat. With /gco, Tomcat knows it should look for a folder gco inside the webapps folder. This one should contain a WEB-INF/web.xml folder for further instructions.
With /MOPO Tomcat knows, having read the web.xml files of all webapps folders at start, it should look for a servlet with the name MopoController. And this MopoController points to the class org.gertcuppens.controller.MopoController. So, Tomcat knows where to find everything.
Try to see whether your Tomcat can find everything inside the folders using your web.xml file.

Web.xml vs weblogic.xml

i have an application :(ijust joined the production team)
and the web.xml is empty .. do i need a weblogic.xml file for the webapp or not and also if the web.xml is empty like the only tag it has is <webapp> </web-app>
what should the content of weblogic.xml be:
i am guessing it will follow the web.xml and will have <weblogic> </weblogic> tags or is there anything mandatory for the weblogic.xml

As a minimum you will need a web.xml and it should not be empty if you use any servlets in your webapp, I think you can probably get away with an empty web.xml if you only use JSPs. You can configure Servlet mappings, security roles etc in the web.xml file. If your application uses none of these thats probably why your web.xml is a bit sparse.
see
http://e-docs.bea.com/wls/docs81/webapp/weblogic_xml.html
for info on weblogic.xml deployment descriptor.

Sun-web.xml memory based sessioning issue

I recently installed Sun WebServer 7.0 Update 8 on Fedora 20. Everything seems to be working fine with my webserver except for the memory based sessioning.
My First Configuration - no sun-web.xml file defined
Expected Behavior - I would assume that memory based sessioning would be used.
Actual Behavior on my local instance - Every 1-2 minutes my session would abruptly end and a new JSESSIONID would be issued. This does not happen on other machines running the same webapp, so it does seem to be a sun webserver configuration problem.
My Second Configuration - using the following sun-web.xml file:
<!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 8.1 Servlet 2.5//EN" "http://www.sun.com/software/appserver/dtds/sun-web-app_2_5-0.dtd">
<sun-web-app>
<session-config>
     <session-manager persistence-type="memory">
          <manager-properties>
               <property name="reapIntervalSeconds" value="20000" />
         </manager-properties>
     </session-manager>
    </session-config>
</sun-web-app>
Expected Behavior - Memory based sessioning would be used
Actual Behavior on my local instance - Same as with no sun-web.xml. Every 1-2 minutes my session would abruptly end and a new JSESSIONID would be issued.
Does anyone see what is wrong with my sun-web.xml file? I'm also not sure if the file permissions/ownerships are correct on all of my sun webserver files. Is there a particular temp file or location that Sun Webserver uses to track active sessions? Or are in-memory sessions completely stored in memory and not on disk? Is there a default sun-web.xml file somewhere that is overriding my settings (and if so, where is it located)?
Thanks for your help!

Hi,
Firstly you should know Fedora is not a support platform. it might work but you could run into a load of issues as your go.
in any case you don't need a sun-web.xml file at all. For any deployed Web app the default session manager is memory. So remove that 1st. After that check that
the requests are really sending a JSESSIONID. This kind of issue can occur when you have a Load balancer.

Russell

Tomcat - web.xml

hi guys
I am running Tomcat 5 on my system. Unfortunatly I hava to make an entry in the web.xml for every test servlet I deploy. Is there a way to call a servlet without an entry in the web.xml?
greets
m.

Hi,
I have a doubt , do we really need to make an entry for a servlet in all webservers at web.xml
I was just thinking like, only those servlet which has defined to have some initparam values that are supposed to used within in the servlet should be made as a part of the entry in an web.xml
for ex: database uri/some servlet information which always changes
Im i correct..
Please tell me more abt the same..

Web.xml, struts and ssl

Hi there,
on our projects web pages we use struts, to combine the html of our pages with the java code behind. To enable SSL I added a security constraint to the web.xml:
     <security-constraint>
          <display-name>SSL Constraint</display-name>
          <web-resource-collection>
               <web-resource-name>secured login resource</web-resource-name>
               <description></description>
               <url-pattern>/index.html</url-pattern>
               <url-pattern>*.do</url-pattern>
               <http-method>GET</http-method>
               <http-method>PUT</http-method>
               <http-method>POST</http-method>
          </web-resource-collection>
          <auth-constraint>
               <description></description>
               <role-name>authenticatedUser</role-name>
          </auth-constraint>
          <user-data-constraint>
               <transport-guarantee>CONFIDENTIAL</transport-guarantee>
          </user-data-constraint>
     </security-constraint> Some of our web pages need to use no SSL. So I added (for first testing) a second security constraint to the web.xml and defined which pages should be without SSL:
     <security-constraint>
          <display-name>No-SSL Constraint</display-name>
          <web-resource-collection>
               <web-resource-name>businesstransaction resource</web-resource-name>
               <description></description>
               <url-pattern>*.go</url-pattern>
               <http-method>GET</http-method>
               <http-method>PUT</http-method>
               <http-method>POST</http-method>
          </web-resource-collection>
          <auth-constraint>
               <description></description>
               <role-name>authenticatedUser</role-name>
          </auth-constraint>
          <user-data-constraint>
               <transport-guarantee>NONE</transport-guarantee>
          </user-data-constraint>
     </security-constraint>As you can see, I exchanged *.do with *.go for testing. I simply defined all actions I want to be used without SSL with a .go instead of a .do in the struts.config.
In principle it works, but there is a problem: The default behaviour for struts seems to be that the name of the new action is posted in the url at the end of the standard starting url.
Our url starts with https://localhost:9443/client-web/, and whatever action I start, this url text in the browser window never changes, regardless of wether the next action would be protected or not.
First I thought my url pattern would be wrong, or the user or whatever. But then I found out, that when changing the url in the browser window by hand to http://localhost:9080/client-web/ it works. The web page then is without SSL active. And when I manually change the url while viewing a page that is meant to be SSL protected, the browser automatically changes to the SSL adress.
But then again, moving to a page without SSL does not enforce the browser to change its adress to the no SSL String. So again, SSL is active though a non secure access would be allowed.
Anybody has any idea how to change this default behaviour? It would be important to not only tell the server that non secure would be ok, but to actually USE non secure connection automatically.
The internet explorer is not able to upload files in SSL mode (though any other browser is able to), and our customer insists on using IE. And to tell the users "oh, just edit the line there in the window manually and reload the page will help ... or use Firefox" will not be a suitable solution.
Regards, Rommie.

There is a plugin called sslext which will do most of what you need.
http://sslext.sourceforge.net/
I think the last time I used it I made some changes to the plugin source so that I could force non-ssl to be the default behavour unless SSL was explictily stated in struts.config, but can't remember for sure. Bottom line is it will do most of what you need and can probably be modified to do the rest without too much trouble.

Servlet cannot be preloaded given web.xml is defined in Weblogic 10.3...
