In web.xml which tag executes first.

Hi All,
Could any one please tell in web.xml whether Filter tag gets execute first or Security-Constraint tag?
Thanks,
Swapna Soni.

In web.xml <web-app> is the root tag the container loads the web.xml when ever the application is deployed or when ever the server is started or restarted or redeployed the application In the same sequence as defined in the sun xmlschema

Which will execute first in File Adapter (parameter,Identifier,module)

Hi,
I have written a module for my sender file adapter, and choose FCC to parase my complex structure...here my doubt is whether adapter module will call first or FCC which is there in Identifier tab in file adapter?
Regards,
Irshad.

Chandras sekhar,
i have already seen that blog...
could you plz read my message once again?

ya i got it..Call sap adapter module will store the message in send queue.
just want to know which module is building the xi header whether it is same call sap adapter module or is there any specific module which will convert native message to xi message.
Is call sap adapter module is the responsible for building the xi message header with the help of cpa lookup? if its so again confuse for me.....
In File adapter we have 3 tabs one is parameter identifier and module...As u said first parameter tab will run as per FCC/ File message protocol then this parsed/content of text file will be input to the module tab .in this module tab we have custom modules and standard module these modules are executed in the same sequence as mentioned.
what is the module name which converts native message to xi message?

Which is executed first? af:setPropertyListener and af:commandButton's actionListener

I have two test apps.
First app:
It has jsf pages. And I have a few fields and a button on the page.The backing bean for my page has a method prepareToBeUpdateOrderRelease(ActionEvent ae).
My button looks like this:
                       <af:commandButton text="Update" id="cb3"
                                          binding="#{backingBeanScope.backing_editOrWithDetails.cb3}" action="update"
                                          actionListener="#{backingBeanScope.backing_editOrWithDetails.prepareToBeUpdateOrderRelease}">
                            <af:setPropertyListener from="#{backingBeanScope.backing_editOrWithDetails.toBeUpdateOrderRelease}"
                                                    to="#{pageFlowScope.toBeUpdatedOrderRelease}" type="action"/>
                        </af:commandButton>
When I run the page, I can see from the printouts on the integrated weblogic console, actionListener is called first, then setPropertyListener is called.
Second App:
It has jspx pages. I have a few fields and a button on the page. The backing bean for my page has a method prepareToBeUpdateOrderRelease(). And this method is called in getTheUpdatedOrder().
My button looks like this:
                              <af:commandButton text="Submit Changes" id="cb1"
                                                  binding="#{backingBeanScope.backing_getOneOrder.cb1}"
                                                  action="callUpdate">
                                    <af:setPropertyListener from="#{backingBeanScope.backing_getOneOrder.theUpdatedOrder}"
                                                            to="#{pageFlowScope.toBeUpdatedOrder}" type="action"/>
                                </af:commandButton>
The page works fine as this.
But if I want to use the same way as the first app, which is using actionListener, the page will fail, because of a NPE. From the printout, I can see setPropertyListener is executed before actionListener.
The only difference between the two apps is jsf vs. jspx. Is this the cause of the difference of the execution sequence between setPropertyListener and actionListener? Thanks.

User, please tell us your Jdev version!
It's a bug and feature. Check prsync.com/oracle/setpropertylistener-and-setactionlistener-might-fire-too-late-when-using-facelets-468522/ for an explanation.

Strange web.xml tag error deploying on jBoss 4.0.5 / java5 / ejb3 : local-h

Hi.
We have an ejb3 / jsf / Java5 app that lives quite happily on OC4J standalone.
When i try to deploy it on BEA 10 (tech preview) or jBoss 4.0.5 - ejb3 it throws the following:
[org.jboss.web.tomcat.tc5.Tomcat5] Problem in init
org.jboss.deployment.DeploymentException: Failed to parse WEB-INF/web.xml; - nested throwable: (org.jboss.deployment.DeploymentException: expected one local-home tag)
It's asking for the local-home tag.
We have quite a few <local> tags spread around, but no need for <local-home> (that seems to me as a ejb 2.x web.xml DTD tag for me).
Why doesn't oc4j bother me, and bea or jboss do ??
What is the standard ?? And/Or why isn't it implemented the same way ??
Any clues ..?
servlet motor (2.4, 2.5 ??)
Thanks a lot.
js.

Do your standard deployment descriptors (ejb-jar.xml, web.xml, etc.) refer to the latest
Java EE 5 schema versions? The ejb-ref element was changed in
Java EE 5 to make local-home optional, since it's not needed to express a business interface
dependency. It's either that or the schema versions in the tech preview itself are not up to date.

WEB.XML gives me an error while deploying a Web Application in Weblogic 5.1

I have a Web.xml which I copied the one from their documentation and edited for my servlet specific data. When I try to deploy it I am getting the following error.

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.

Web.xml file problem in tomcat

Hi i need help in this... its urgent
currently i just subscribe to a web hosting site and i need to start the private tomcat in the web server..
The followings are the instructions and i have follow them but i do not know how to create a web.xml file to store in the folder indicated for example a HelloServlet that im testing :
To setup servlet, you need to configure servlet into the file web.xml which needs to be placed in /var/www/html/WEB-INF directory.
www root directory or webapps:/var/www/htm
Classes directory located in: /var/www/html/WEB-INF/Classes/
There you will need to upload your Java class file.
Our default url-mapping for servlet is: /servlet/*
To check servlet in your browser: www.mydomain.net/servlet/HelloWorld
Jsp Files - Upload anywhere in /var/www/html
all the above steps are follow except the web.xml file which i suppose to write and store in the folder... but i actually try to write one but i still cannot load my servlet on the webpage... test on standalone tomcat works.
pls help its urgent!!!

first sorry about cross posting the subject. i didnt know i am not suppose to do that. i post in a few forums that are related to my topic. sorry
The tomcat on the web server is of version Private J2EE / Tomcat 4.1.29 and the standalone tomcat i am using is also tomcat 4.1
the web.xml in my standalone server in root/web-inf/ is as follows and it is configure for authentication purposes. It works together with the tomcat-users.xml located on conf directory

using this web.xml, my stanalone web pages works fine for all servlets and jsp. however if i copy this over to the web server, i still cannot load my servlets and jsp. moreover it doesnt work for authentication purpose anymore. i don't know why too
i have try the codes you write before and it also doesnt work
the problem is i cannot get the support form the web hosting site. This is the link that suppose to teach me but it doesn not tell me how to configure my web.xml

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.
bgOnline

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.
HTH.

Web.xml security

Let�s say that I have 2 main groups, group USER and group ADMIN.
Now let�s say that I have 3 other groups, groups A, B, and C.
The structure in OCS would look something like this.
group USER has members group A, group B, group C and group ADMIN
group ADMIN has members that are just users, no groups
From our application to perform a isUserInRole(group B) would group B have to appear in the web.xml file or should I only have to have group USER in the web.xml file?

Hi,
the web.xml file contains all groups that you reference in URL constraints in teh web.xml or call via isUserInRole(). Note that you also can use different names in isUserInRole() but then you need to use the role-ref element to map it to a role that exists in web.xml.
Note that J2EE doesn't support RBAC in the web.xml, which means that there is no role that is a member of a role. OC4J supports this from the security provider site, but still this isn't the case for J2EE itself.

10.1.3 - OEM Deployment generating invalid orion-web.xml

Hi,
I've playing around with OracleASjms resource adapters, JMS Connector, etc - with some good results. I noticed that one of my test applications, when deployed (via OEM) gets an orion-web.xml which is not according to the XML schema and am wondering whether this is designed behavior.
In my servlet I'm using some logical names for javax.jms.ConnectionFactory and javax.jms.Destination, which I specify in the web.xml. Deploying the ear file I get the change to resolve environment references to 'physical' JNDI locations. I map the logical javax.jms.ConnectionFactory to an OracleASjms resource adapter connection factory (which in turn is pointing to an JMS ConnectionFactory) and the javax.jms.Destination I map to an OracleASjms Administered resource.
The applications deploys and works fine, however I have a question with respect to the orion-web.xml that Oracle is generating based. More specifically I see (<....> are replaced with actual values):
   <message-destination-ref-mapping
         name="<logical name>"
         location="<OracleAsjms/Administerered Object>"/>The element message-destination-ref-mapping isn't declared in the XML schema for orion-web.xml, but still it works, how come?

http://www.oracle.com/technology/oracleas/schema/index .html
http://www.oracle.com/technology/oracleas/schema/orion-web-10_0.xsd
Thanks, jvissers. It seems that orion-web-10_0.xsd is outdated. It is probably that it was posted for the 10.1.3 preview. When the 10.1.3 production release is available, at least that schema is not updated. Hmm, all things that are changing but kept at different places are just very susceptible to inconsistency. Hmm, OracleAs team should probably make automated tests to make sure that they are in sync. (I am just thinking loudly). Let me try to communicate to someone who can further take care of this matter of outdated schemas. Thanks again, jvissers.
Where did you look?Inside my oc4j installation! oc4j will not go to the web to download the oc4j-specific schemas in case of need. The orion-web-10_0.xsd is at OC4J_HOME/j2ee/home/lib/schemas.jar!META-INF/orion-web-10_0.xsd. That is where I looked. So the orion-web.xml generated by OEM is indeed valid.

Problems with the tag error-page in web.xml

hi all, here is my code in my web.xml:
<error-page>
<exception-type>java.sql.SQLException</exception-type>
<location>/ex.html</location>
</error-page>
it seems not to work, because my JavaBean where its the code to connect to my database and execute a query has an error i made it at purpose to see if the error page works, my JavaBean reports an error: column name not valid but the error-page didn�t work, i use a servlet which instantiates my JavaBean and then my servlet redirects to a JSP, obviouslly if an error occurs my servlet didnt redirect to any place, here is the code into my JavaBean, if anyone could help me i really appreciate it...
public BeanLista seleccionaCliente()
int nBandera = 0;

}

Can it be because you are catching your exception? Why don't you try throwing the same exception in the catch block and let the server handle it for you.
Just a guess... Hope it works.

Using security-constraint in web.xml; not recognizing url-pattern tag

I am creating a very simple jsp application within JDeveloper 10.1.3.1. I have 2 jsp files...a readData.jsp and a maintainData.jsp. I would like to deploy this application to Oracle Application Server 10.1.2.2. I would like to use Oracle Internet Directory with Single Sign on enabled. The deployment to OAS works fine. For the security, I would like an administrator user to get to both pages...and a user to only be able to see the readData.jsp. I used the security constraints on the properties of the web.xml file within JDeveloper. Here is my web.xml file:
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

<security-role>
<role-name>usr_all</role-name>
</security-role>
<security-role>
<role-name>adm_all</role-name>
</security-role>
</web-app>
When I deploy to OAS I added an OID account to the adm_all role...this works fine I can log on as that user and get to both jsps. But, when I add my user to the usr_all role within OAS I try to log on to the app...I then enter my SSO username and password and I get Access Denied errors from my browser when trying to access either page. I am confused about the <url-pattern> tag...is that relative to a directory within my deployment? Most of the examples I have seen use servlets...so I was wondering if I can even use the <url-pattern> tag to restrict/allow access to individual jsps? If someone could point me to some documentation on this set-up I would appreciate it!
Thank you.

I was able to get this to work. By doing the following:
<security-constraint>
<web-resource-collection>
<web-resource-name>adm_full_access</web-resource-name>
<url-pattern>*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>adm_all</role-name>
</auth-constraint>
</security-constraint>
I was restricting access to all other groups by uisng <url-pattern>*</url-pattern>. Any other security-constraints set-up after that will not work. So saying * requires usr_all will restrict ALL webpages to ONLY adm_all, regardless of what future constraints say. So, my first security-constraints lists all directories or pages that every user can access. My next security-constraint then list resources that only my admins (adm_all) can acess. Any other security constraints then are set-up for each user role that I have...if adm_all should have access to these then the <role-name>adm_all</role-name> is added to each security constraint.

In web.xml which tag executes first.
