Is it possible to have a dynamic web-xml ?

Hi all,
I have the following problem: the mapping of a Servlet
is subject to change depending on the host on which
application resides. That is if my Servlet is installed
on Host1 the mapping will be:
<servlet-mapping>
<servlet-name>
myservlet
</servlet-name>
<url-pattern>
/host1
</url-pattern>
</servlet-mapping>
if on the other hand it's installed on "AnotherHost" it should be:
<servlet-mapping>
<servlet-name>
myservlet
</servlet-name>
<url-pattern>
/AnotherHost
</url-pattern>
</servlet-mapping>
Is it possible to have it done without changing web-xml every
time I move the application from one host to another?
Thanks a lot
Francesco

Hi,
Is it possible to have it done without changing
web-xml every
time I move the application from one host to another?You could change this during your build process (e.g. Ant) if you have one, otherwise I think you'll have to manually edit it yourself.
Cheers,
Matt

It is possible to have a dynamic Oracle Label Security procedure/script to configure data label (compartments and data label) for multiple rows at same time?

A single script which can be run below mentioned commands... instead of using multiple manual steps for configuring data labels. Is that possible and how? Having bulk of data where OLS need to be applied.
exec LBACSYS.SA_COMPONENTS.CREATE_COMPARTMENT
exec SA_LABEL_ADMIN.CREATE_LABEL

Have you ever answered this question? If not, have you tried to use the "HIDE" property on your table_options?

Is it possible to add a filter to a webapp without declaring it in web.xml

Hello,
I'd like to add a filter in my web.xml file, but without declaring it in my webapp.
Indeed, I have multiple webapps, and I'd like to have a common web.xml file that should be directly included in all the webapps including this package ?
Is it possible or not ?
As for JSF, it is possible to add faces-config file by putting it in the META-INF of the package.
Thanks in advance.

Your title and your question are opposites...
A filter must be specified in a web.xml to be used. That doesn't mean the Filter's class HAS to be in your webapp, it just must be accessible to the Servlet container (you could place it in the common/classes directory or shared/classes directory or even the server/classes directory).
I've not tried it, but I see no reason why you couldn't declare the filter and filter-mapping in the server's web.xml which would then filter all requests in all webapps.

but when i deploy this using tomcat and try to put url as this,

Its not identifying welcome file from web.xml
I am getting error like this,
The requested resource (/project/) is not available.
How to resolve this,
Thanks,
Vinutha

This might help:
http://forum.java.sun.com/thread.jspa?threadID=696586
As well, you might have to change the servlet-mapping in your web.xml. The url-pattern, I think, needs to be .xhtml. Your login.jsf file in the welcome list will need to be renamed to login.xhtml.

Web.xml question

Hi Guys!
I ran into a small problem.
Im using the struts tiles framework to redesign a shopping cart .
In the new framework,there are multiple websites(user interface tiles) that use the same servlets at the back end to process the requests. The control is passed back to the website that called the commonly shared servlets once the computations are done.The servlets, the various websites that use the servlets all reside on the same server and are a part of the same project.
The whole project shares a common web.xml file.
I was just wondering if each of the tiles can have thier own web.xml so that the servlet context can be loaded from them.
The directory structure is like this
Tiles Framework
-Servlet Source
-web.xml
-tiles (folder)
---tile1(folder...contains the 1st website)
---tile2
---tile 3
The reason being that in the older version of the shopping cart, the web.xml was used to load specfic contexts in the servlets.
Is it possible that wach of the tiles has its own web.xml ?
if so, does it require any configuration in the overall project.
Thanks.

If I understand the web.xml file correctly, there should only be one per project. But if it's just a matter of loading props for each of the tiles, can't you just have a different properties file for each tile?
I can't imagine a situation where you'd be required to have multiple web.xml files within the same project. Can you explain why you can't just have several regular property files & read from them instead?

Significance of context param in web.xml to initialize any variable?servlet

I am writing a standalone web appplication for rss (xml) creation where i am having jsp servlets class etc.
Now to write rss.xml and read it back in application i have temporarily used c:\\rss.xml but to make it capable working in web application which can be uploaded in website i need to make it configurable i need to kep it in context param of web.xml and in init() method of servlet of my application what exactly i should do there.what i have tried is this :
public class Startup extends HttpServlet {
private static String rssFeed;
private ServletContext ctx;
Logger log = Logger.getLogger(Startup.class);
public void init(){
log.debug("Initializing APPLICATION CONTEXT Variables");
ctx = getServletContext();
rssFeed = (String)ctx.getInitParameter("RssFeed");
log.debug("Rss : " + rssFeed);
String rssFile = this.getServletContext().getRealPath("") + File.separator + "WEB-INF" + File.separator + "rss.properties";
Properties property = new Properties();
try{
InputStream propertiesFile = new FileInputStream(rssFile);
property.load(propertiesFile);
catch (IOException e) {
log.error("IOException during domainValuesList file Reading");
e.printStackTrace();
log.error("Exception while loading AllowedDomainValues file");
log.debug("Domain Values Lists Updated");
/** Get Host Name (Server Name) where application is hosted on
public static String getRssFeed(){
return rssFeed;
after that i called this startup servlet class in other servlet taken this getRssFeed()
stored it as string passed as parametr to other class where i need to call it but there i am getting null pointer exception which says not initialized.
even what i have written in web.xml is here:
<context-param>
<param-name>RssFeed</param-name>
<param-value>c:\\rsshandler.xml</param-value>
</context-param>
<servlet>
<servlet-name>Startup</servlet-name>
<servlet-class>src.Startup</servlet-class>
<init-param>
<param-name>RssFeedConfig</param-name>
<param-value>/WEB-INF/rss-config.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>Startup</servlet-name>
<url-pattern>/Startup</url-pattern>
<load-on-startup>1</load-on-startup>
</servlet-mapping>
i tried what i know or understood but its not working.
one more thing i have doneis:created rss.properties files in web-inf
lines added are
rssfeed=c:\\rsshandler.xml
but even i am not getting this why
or what sholud i do here.
this thing needs to be configurablewhich we can change later easily.
any suggestions.
thanks

Ben -
There can be init params for the servlet or for the servlet context. For the servlet, this looks like:
<servlet>
<servlet-name>InitServlet</servlet-name>
<servlet-class>package1.InitServlet</servlet-class>
<init-param>
<param-name>message</param-name>
<param-value>Hello From Initialization Parameter</param-value>
</init-param>
</servlet>
in the web.xml file, and is accessed using:
public void init(ServletConfig config) throws ServletException
super.init(config);
message = config.getInitParameter("message");
For a servlet context init param, you define it as you did using the web.xml settings editor:
<context-param>
<param-name>hello</param-name>
<param-value>hi</param-value>
</context-param>
This is accessed using:
public void init(ServletConfig config) throws ServletException
super.init(config);
message1 = config.getServletContext().getInitParameter("hello");
Hope this helps,

Init-params in web.xml are not loaded (Tomcat 4)

Hello all...
I register a servlet in webapps/<my-servlet>/WEB-INF/web.xml file, and pass 1 <init-param> tag. The file gets parsed (I know because when I made errors tomcat complained during initialization). However, when in the init method of the servlet I try to access this parameter, its not there. In fact, the servlet has NO init params at all.

I know what the problem is. If you call servlet with the default URL (http://host/app/servlet/package.Servlet) than Servlet DOES NOT read init parameters. I don't know why it was designed this way.
To make servlet read init parameters, you have to assign it a name and then call it with that name, like this:
<servlet>
<servlet-name>ServletName</servlet-name>
<servlet-class>package.ServletClass</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ServletName</servlet-name>
<url-pattern>/app/path/ServletName</url-pattern>
</servlet-mapping>
You can then call servlet using path specified in url-pattern and read init parameters in the normal way.

Struts web xml

Hi there,
I want to define my own error pages. Someone told me that it's possible to define them in web.xml
I use this somewhere in my code:
response.sendError(HttpServletResponse.SC_UNAUTHORIZED);
I want to keep this, but I want to make my own styled page.
Can someone help me?

in your web.xml for each error
<error-page>
<error-code>404 (500,...)</error-code>
<location>anurlto your custom page </location>
</error-page>

Question on web.xml and login

Hi all
I am doing a web-based project, registered user need to log in before they view the member area pages.
I have created a directory, called "client", in the Tomcat 4.1.24/webapps/ROOT/client I have put a index.html in the client directory. This index.html only can be viewed by the client after log in.
For the best of my knowledge in Tomcat, in order to do this, I have created a web.xml in Tomcat_home/webaggs/ROOT/WEB-INF/web.xml, in the url-pattern section, I put /client/* to tell the tomcat server that index.html in client directory is the first page after user login.
The problem is, I couldnt see the member welcome page after I login as a member, the browser gave me the error: HTTP status 400 - Invalid direct reference to form login page. However, if I specified the address http://localhost:8080/client/index.html , it show me the login page and after I input the username and password I can see the member welcome page.
I dont know whether is something wrong with the web.xml or I should do other thing to let the server know which is the first page after member login.
Thank you very much
Kelvin

Wow, you really are in the wrong place with this query, its not really even java ;o) This is the new to java forum! Perhaps you would be better off (in fact I know for a FACT that you will be as I have seen answers to identical problems there) in the Tomcat-user list...

Configuring web.xml for OpenSSO

Hello!
I am developing simple web application and want to use opensso in my web application.I have downloaded opensso,deployed and configured ,so i dont need how to configure web.xml ,what filters and jars i needed,i have the simple web.xml
<web-app>
     <security-constraint>
          <web-resource-collection>
               <web-resource-name>admin</web-resource-name>

     </login-config>
     <security-role>

     </security-role>
</web-app>so what filter should i add in web.xml so that when i access admins page <url-pattern>/admin/*</url-pattern>it should redirect to opensso s login page?

Yes, I restarted the app server after making changes to web.xml file. No effects.

Maintaining Portal Desk top URL aliases in web.xml file

Hi All,
I am planning to configure portal url alias i.e http://localhost:53000/irj/portal/finance
should take me directly to finance portal desk top.
1) Created a Desktop named finance_desktop
2) Master rule has been set for URL Alias.
3) I need to set URL alias name: finance in web.xml file
4) path for the web.xml file is C:\usr\sap\SID\JCXX\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\web.xml
5) Where exactly i have to change web.xml file
Infact i have seen a pdf "How to configure the J2ee engine deployment descriptor"
Thanks in advance
Regards,
Murali

Hi
indeed one small copy/paste mistake from me ... sorry for that...
After you copyed the large chunk of code (as i discribe in step 1 and 2) you must rename:
<param-name>portal</param-name>
to
<param-name>portal/finance</param-name>
so then that part of the web.xml will look like this:
<init-param>
<param-name>portal</param-name>
<param-value>
anonymous=0,proxy=0,low_bandwidth=0,include_in_url=1,include_application_name_in_url=1
</param-value>
</init-param>
<init-param>
<param-name>portal/finance</param-name>
<param-value>
anonymous=0,proxy=0,low_bandwidth=0,include_in_url=1,include_application_name_in_url=1
</param-value>
</init-param>
Good luck again...
Cheers,

Display error page using web.xml error-page

I need to dispaly error page when IOException in thrown. How to do that with web.xml error-page tag?
start.jsf
public String doButton1Action() throws IOException{
          String value = getText1().getValue().toString();
          try {
               File f = new File(value);
               InputStream in = new FileInputStream(f);
          } catch (IOException e) {
               throw new IOException();
          return "success";
     }I have this in web.xml:
     <error-page>
          <exception-type>java.io.IOException</exception-type>
          <location>/ioerror.jsp</location>
     </error-page>

I tried that earlier but then I get error just printed to console and HTTP 500 - Internal server error -page, bubt not my errorPage.

Tomcat 3.2.3 web.xml doesnot work in Tomcat 4.0

I have put a web.xml for my web app in wEB-INF directory. It works in Tomcat 3.2.3 but doesnot work in Tomcat 4.0. Tomcat is showing some ParsingException.
Is this true & anyone of u r facing the same problem?
Thanks in Advance

Hi
If you see the Specification the order in which the tags appear is important. In Tomcat 3.2.3 the order is not stressed upon but in Tomcat 4.0 any discrepancy in the order of Tags is immediately noted. See specification for the order of Tags and change the web.xml . Your application should work fine then.
Keep me posted on your progress.
Good Luck!
