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

          > 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

Need api for changing security role in web.xml !!

My requirement is to change the value of the deployment descriptor "security-role" (in web.xml) through an api and inturn to persist the new value in web.xml. Also I need to know if this change is automatically redeployed or an explicit redeployment is needed ? In that case how do I redeploy using an api call ?
I found a lot of apis related to roles like createRole, removeRole etc.. But there are no apis to change the name of the role and inturn persist in web.xml.
Do I need to provide any more information ? Let me know
Thanks,
Karthick

why and when do you change security-role? try to use ant task (perhaph you need xpath also). itÂ´s the better when you perform task about lifeÂ´s cycle of application.
please, describe your problem.
of course in you change web.xml you must restart the application.

JSF - How to set up tag libs in web.xml file?

Hello all,
I have a doubt... that in an JSF application we are using two tag libraries, one for the core and other for html components. Both these *.tld files are jared inside "jsf-impl.jar" file.
The problem is that when i start the web server (Tomcat4.0.6) the console shows that taglib tag must be configured... this means that we have to specify the "<taglib></taglib>" elements in the web.xml file of the jsf application... but how do configure the jar file...
please guide...

Putting the JAR files in WEB-INF/lib and using the standard URIs in the taglib directives are all that's needed; the container locates the TLDs in the JAR files at startup.
If this doesn't work, it's a bug in the container. You may want to upgrade to a later version of Tomcat; 4.0.6 is ancient, and may very well be buggy in this area.

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);

Specifying Case-Insensitive Element Names in XML Schema

Hope someone knows this!
Is it possible to define an an XML Schema Definition so that Element names in the target XML File can be case insensitive.
At the moment my Parser throws an error if the element names in the XML file do not have the exact same case as the definition in the XML schema.
E.g
In Schema i have:
<xsd:element name="HOSTINVENTORYLINE" type="HostInventoryLineType" maxOccurs="unbounded" minOccurs="0"/>
but in xml file i have
<HostInventoryLine field=""/>
or
<hostinventoryline field=""/>
Does anyone know anyway to get around this, so that the parser accepts the HostInventoryLine element in the xml as an instance of the HOSTINVENTORYLINE element defined in the schema.
Thanks in Advance
JJ

You could use substitution groups to handle this. You would need an entry in the schema for each valid capitalization. This won't scale well if you want to be completely case insensitive, but if you only support lower case, upper case, and camel case it should do the trick.
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:complexType name="HostInventoryLineType">
          <xs:sequence>
               <xs:element name="an-element" type="xs:string"/>
          </xs:sequence>
     </xs:complexType>
     <xs:element name="HostInventoryLine" type="HostInventoryLineType"/>
     <xs:element name="HOSTINVENTORYLINE" type="HostInventoryLineType" substitutionGroup="HostInventoryLine"/>
     <xs:element name="hostinventoryline" type="HostInventoryLineType" substitutionGroup="HostInventoryLine"/>

Servlet configuration in Weblogic 5.1.. web.xml vs weblogic.properties..

Can someone please tell me how the <servlet> entry differs from
          weblogic.httpd.register.snoop=examples.servlets.SnoopServlet
          in weblogic properties?
          Do these perform identical functions?


Yes this is the source of my confusiong. It seems to be that WL can be told
          about servlets
          two ways. Firstly through the web.xml file and also via weblogic.properties.
          I don't understand
          why the second one exists.

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 can one use one specific security realm per application ? The realm-name attribute of the login-config tag of web.xml does not make any difference

Hi,
I have different sets of users coming from different databases and using different
roles mapping for each of my web applications. I would like to configure a specific
security realm per application in my weblogic server 7.0 . Is it possible ?
I try to specify the realm-name of the login-config tag from the web-xml deployement
descriptor but it doesn't make any difference. The default realm is always used.
I also would like to tell the Weblogic server to use the default realm in case
the realm isn't specified or isn't found. For example, the default would contains
my admin users.
Thanks a lot for your answer.

I thik this is a common mistake the ralm-name tag in the deployment descriptor is used
just by the browser for display purposes (when it opens the basic auth dialog box) so as
of now there is only 1 active realm which can have multiple providers as Kevin pointed
out
Kevin Lewis wrote:
WebLogic 7 now ignores the realm-name tag (I found that out yesterday).
My understanding is that there is only one realm active at a time for a domain
(I would be interested in being contradicted in this).
However, you can have multiple providers in each category of a realm: authentication,
authorization, etc. Therefore, what you can do is key authentication, et al,
off of some other information. We have our users enter their company, for example,
and use the TextInputCallback to get it. You could also encode something in the
initial page, based on the URL they hit, or whatever, and get that back in your
callback.
You can store that information in your own Principal implementation, and key off
of that in your authorization provider, going to a different database as appropriate,
or abstaining when a specific provider doesn’t have anything to say about a subject.
Anyway, there should be a way to do it, even if it's more complex than you would
have hoped.

Weblogic.servlet.reloadCheckSecs in web.xml not working

          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

Are not interpreted JSTL tags in a JSP page including in a servlet.

Hi people,
I have a project where una page (index.jsp) includes a servlet (MyServlet), that consult a persistence class and get a List of objects (Users),
then the servlet passes the List to a Request object and includes another JSP page (showUsers.jsp). And this is conceptually correct, but don´t works, the JSTL tags are not interpreted in showUsers.jsp.
This is my code...
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

          request.setAttribute("users", (ArrayList) um.getUsers());
          request.getRequestDispatcher("/showUsers.jsp").forward(request, response);

I suggest putting System.out.println() throughout your servlet code and out.println() in your JSP pages to see exactly what is called and when.
As a general rule, JSP files are to display data only, and submit back to a servlet. The servlet does all the business logic and dispatches to the appropriate >JSP page. The JSP shouldn't have any business logic. Including the servlet looks kinda like including business logic. Actually, in a MVC design, your >presentation, control, busines, and database layers have their own isolated responsibilities.
I suggest the servlet put data as one java bean in request scope via request.setAttribute() and dispatch to the JSP page. The JSP page gets the data via ><useBean> tag. The JSTL gets the variables from the useBean tag and uses the data from there to display it. Really, this is my web.xml file...

Respect of your last comment, I am not a expert in MVC, but I understand that the view layer can make calls to the Controller layer, I am wrong?

It's not. However thats not code, but the generated HTML.
As Balusc pointed out it's the result of running this JSP page without importing the tag library at the top.
Because the tag library is not declared, it treats the <c:forEach> and other tags as template text, and basically ignores them.
It then evaluates the ${items} attribute as an expression in template text, calling toString() on it.
Cheers,
evnafets      The file showUsers.jsp are included into the index.jsp page, that's have the header taglib. Could this works?

By the way, I dont think this is the correct format for the foreach tag:

Eclipse, WTP, Servlets and Web.xml

I wonder if you could help me.
I am using Eclipse and Web Tools Platform.
In eclipse, when I create a Servlet, I believe the servlet details (such as name, class, url-pattern) should be included into web.xml file automatically. However, this is not happening.
Would you know how I can configure Eclipse and WTP to automatically write Servlets details into web.xml files.
Thanls

Thanks for the reply
I have Eclipse 3.2 and WTP 1.5
Yes, I am creating my Servlet in a project under the Dynamic Web Projects.
I deploy my WAR file using the 'Export' menu.
Now, I have manually added the servlet details into the web.xml file:
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>com.mycom.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorld</url-pattern>
</servlet-mapping>
I am accessing the servlet as:
http://localhost:9090/MyFirstServlet/HelloWorld
But I still get HTTP 404 error when accessign HelloWorld servlet. I am not sure what I am missing.
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.
Somethink is wrong .
The following is the code from the GroupRegistration.java file
and follws the web.xml file.
Please Help.

I apreciate your time.
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.

Do I must put ALL my servlets inside the web.xml file?

Hello everybody,
I am trying to migrate from Webshere to TOMCAT a project with severals packets, one of those have 15 servlets and some classes.
Is there any way to use the servlets without have to declare each one inside the web.xlm file ?
Thanks in advance.

All servlet definitions go into web.xml, though not the actual servlets themselves :) . Say if you wanted servlet A to have a different mapping you would define the mapping in web.xml to something other than the standard one.

Can we change the web.xml file name???????

can we change the name web.xml and struts-config.xml file to other name.....if yes, then how..........

you can change the name of struts-congig.xml file
and change the strut-config file name in web.xml also.
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <servlet>
        <servlet-name>action</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>And you also try rename the file web.xml and run the application and check what is happening...

Not specify servlet tag role-name - web.xml
