Navigation of JSF pages on Linux

Hi ,
I am in process of developing an application containing JSF pages . I have deployed the EAR on WAS on windows machine and JSF pages developed are working fine and I am able to navigate the pages without any issues.
However , when I deploy the same EAR on WAS which is installed on LINUX , JSF page navigation has stopped.
There is no error as such coming on the console , I need to check the system.out/err files for any error .
Do I need to make any changes in faces-config.xml ?
Advices/Suggestions will be greatly appreciated .
thanks...

When you say the "navigation has stopped," what do you mean? The page refreshes but returns the user to the same page? The page doesn't refresh? The user is taken to a blank page?
You shouldn't need to make any changes at all. I develop on a Windows machine and deploy to a Linux server on a daily basis without any modifications before releasing. I'm using WAR files and Tomcat, but JSF applications should run just the same either way. The only thing that immediately comes to mind is the JDK installed on Linux might not be adequite. For example an older version or jre instead of jdk.

Conditional rendering of JSF page depending on Navigation case

Hi
Can we conditionally render the JSF page depending the navigation case, which brought us in that page..
Lets say that a page A does both Edit and create operations , we have two navigation cases "edit" and "create" directing to this page from main page. can we modify the components in the page depending on the navigation case.
Thanks in advance
Pradeep

Hi Grant,
your reply was helpful. i got into another scenario :-) where i need to know the navigation case which brought us into the page.
I have a page flow in adf which can be called by client applications both as a popup or a regular window. the ADF's dialog framework more or less solves my requirement. But to return values from dialog, i have to use "returnFromDialog" method on click of button in the popup window. as i am reusing the page i would write a conditional statement to show diff behaviour when launched as a popup.
my problem is that i do not want client application to set any parameter in the managed bean (this would get client apps into the implementation issues, causing unnecessary complexity). This again brings me back to the same question ability to KNOW (get handle of) the "navigation case".

How-to get attributes from one JSF page redirected to another?

How do I send information from one JSF page when the navigation rule redirects it to another?
When JSF navigation does a forward I can use request.setAttribute() in the from-page and then use request.getAttribute() in the to-page, but this doesn't work with <redirect/>.
Regards,
Al Malin

The process scope in ADF Faces solves this. See:

I'm building my JSF pages based on a template that has a navigation pane which contains command navigation items , every one of them (command navigation items) appears as a link at runtime and calls a JSF page , I wish to get the initial state for any page when leaving it then entering such page again , and I would like to know what is the suitable place to write the code to do this task.
many thanks !

Clear the cache by adding the following to each jsf page.

Problem with Non JSF Request to JSF Page

Hi All,
I am working on dynamic controls generation based on the request come from non jsf page
For the first request, pageworks perfectly. but when we go for second request, it is not rendering and I am getting same old page.
What I have identified is if I have 2 pages as JSF, application is not giving any problem.
For this I have written small test application contains both JSF pages only.
page1 contains 3 submit buttons.
When submit buttons are clicked based on the request, I get, am able to see the dynamic controls.
SO there is no problem with JSF PAGE to JSF Page Communication
Now I have done some changes in First JSF page. Instead of submitting directly I am submitting the page through JavaScript which is nonb JSF request. There I am facing the problem and based on requested qaction I am not able to see correct rendered page based on the requested action.
Any Idea why it is giving problem for non JSF requests??
Thanks
Sudhakar

For Your Convenience in understanding the problem
I am pasting entire test code
Page 1 -- (here page2 is Page1 and Page1 is page2 - some naming convention errors :) )

Same JSF page is being displayed after submitting form

I have a situation where some of my JSF pages occassionally misbehave. For example, sometimes when I click a <h:commandButton/> (which is located within a <h:form> tag) the action which the button is wired to is not executed. Instead the same page is displayed.
Please note that this glitch happens intermittently with no fixed pattern.
It is also interesting to note that the data which the user enters (prior to clicking the button) on the JSF form is also lost and has to be re-entered again by the user.
Functionally, this is only a minor problem however from a usability perspective this is a major major problem!
I have tried:
Adding <h:messages /> components to jsp pages in order to see if there are any errors.
Verified the spelling of the outcomes ("success", "cancel") in my navigation rules and in the action methods.
Verified the spelling of my bean in the definition as a managed bean in the faces-config.xml file and in the jsp page.
Verified the name of my action method, in the jsp and in the backing bean.
Checked by logging if the action method is reached.
Used the jsf phase tracker to print life cycles phases. However, when the page "misbehaves" this misses out all the application level phases i.e only phases restore view and render response are actually passed.
Created getters and setters for all bean attributes
I am desperate to fix this. Has anybody found a solution to this problem? Please let me know!
Thank you.

I am using JSF version 1.1 and the application server I am using is BEA WebLogic Server 9.1.
The page is one in a series like a "bread crumb" trail or in the style of a wizard if you like. The user goes from one page to the next and can go back if he so wishes.
I have a user form. One part of the form requests the user to enter an email address and then click an "Add" command button. However, sometimes instead of adding the email address to the data table the same JSF page is displayed when the button is clicked and all the data is lost, resulting in the user having to re-enter all the information on the form again!
Hope this helps.

Blank index.jsp and some jsf pages within WebContent folder

Hi dear all,
I have a problem with a blank index.jsp forwarding to a jsf file i.e. <jsp:forward page="/pages/xxx.jsf" />
I have tested with index.html (is showing with right contents), index.jsp (page loaded but blank), index.jsf (page loaded but blank).
Web Server details : Tomcat 6.0.18 running on Linux.
Folder structure is

But direct access to jsf files within pages directory is showing, which is not desirable.
Can someone advise me why?
Many thanks and have a good day,

JSF pages to display content from external URLs

Hi,
Is it possible for a JSF page that uses ADF controls, and the PanelPage component to provide menuing, etc. to actually allow a HTML page (accessed via a URL to an external site/application) to be displayed in an area within the JSF page?
For example, clicking a menu item to an external HTML page results in the page being displayed in a Frame or similar within the JSF page?
I've tried the FrameBorderLayout control and Frame control to try to embed a Frame to display such a page via the target setting for a menu item, but that doesn't seem to work. At least not when within a PanelPage. It works within a basic JSP page.
I would have thought it would be possible for a JSF application to incorporate HTML content from other sites/servers as if part of the application. Even if this meant defining "wrapper" pages of some sort to effectively link these into the JSF application as part of it's navigation rules.
Or am I missing something?
Gene

Thanks,
Yes, using an iFrame tag within a verbatim tag worked, allowing me to specify an external URL to a page which is then displayed at the location where I placed the verbatim tag. I need to investigate sizing/border settings, but at least I now seem to be able to embed such pages.
This works.
I tried jsp:include as well, but that only seems to allow relative URLs to pages that a part of the application. And using the c:import JSTL tag would import a page at an external URL, but didn't seem to position it where I wanted it.

Using Business Components in JSF pages

I have several questions about using BCs in JavaServer Faces pages. I'm new to the JSF-BC development world.
Here's what I'm trying to accomplish: a salesperson gets a call from a customer requesting a quote. The salesperson selects the URL for my RFQ form and begins filling it out. If there is an existing customer record in the company's database, the salesperson wants to be able to load customer info into the form from the database, rather than typing it all in. Reasonable enough, and probably simply enough.
But it's kickin' my butt. I've created the domain objects (including one for the customer database, call it "CU") and the model objects (a View Object that filters out all fields but those needed on the form, an Application Module with a View Object Instance). Initially I am routing from the main form window to a dialog window where I am hosting the customer selection components, intending to return to the main window with the selection. On the dialog window I've dropped the VO and configured it to be an ADF Navigation List (which gets implemented as an af:selectOneChoice component). So far so good. The navigation to and from is working fine. The selectOneChoice list is being populated with the first range of returned records. Here's where I'm stuck.
First of all I can't figure out how to kick the iterator into sending additional records after it's first range. You can scroll down to the end of the list in the selectOneChoice component but nothing happens after that. I know I can set the iterator's range to 0 to get all of the records dumped in at once, but that takes way too long. Any ideas?
Secondly, when a selection is made, how do I access the selected data? I have set up a ValueChangeListener method in my dialog's backing bean that gets the NewValue() from the event object, but that value turns out to be the index into the collection of selectItems. How do I get the value of the data that shows in the list? Is that the label of the selectItem? If so, how do I access it? What I really want is to get the entire row of data represented by the returned index, but I'm lost as to how to do that. Any help would be much appreciated.
At some point I want to let the salesperson type in a partial customer name and then retrieve only records matching the query's where clause. I see where I can create a bind variable on the view object, but am not sure how to pass the partial name value from the main form to the dialog. Currently I use an EL expression in the Action attribute of an af:selectInputText component to navigate to the dialog and I don't think I can pass parameters with that. I guess I would have to switch to using a method binding to a backing bean, eh? But even if I can get the partial name value to the dialog, how do I bind that value to the bind variable of the VO? (the VO that is already bound to the af:selectOneChoice component in the dialog.)
And I am totally open to alternative suggestions for how to accomplish the original intention of all of this. Thanks for any guidance.
Johnny Lee

Thanks, Shay. That has gotten me a few steps further along. I modified my VO by creating a bind variable and modified the SQL to use this variable in it's where clause. I generated Java for my AppMod (which I hadn't done before, preferring to keep things simple) and created a method to supply a value to my VO's new bind variable. I need a little more hand-holding, though, to wire an input text field & button (or af:selectInputText?) to both the AppMod's new method AND the data component that will display the query results.
"...drag the exposed method as a button onto a JSF page." That's easy enough, but I haven't yet figured out from the examples how to associate the value of an input component with the parameter of the AppMod's new method. It's getting late, I'm starting to see cross-eyed so I will sleep on this and take another look in the morning. Thanks for your help.

Adding a footer in JSF pages

Hi,
How can we add footer to a jsf page? I tried using Tiles framework. But it uses a TilesServlet class which is not there any more. I looked in almost all versions of struts jar but couldnt find it. Now i have created a footer jsp and added it inside every other jsp using f:facet tag
<h:panelGrid width="100%">
<f:facet name="footer">
<f:subview id="foot2">
<jsp:include page="/footer.jsp"/>
</f:subview>
</f:facet>
</h:panelGrid>
In my footer.jsp, i have three command links which i want to use for navigation between different pages of application. In faces-config.xml, I have created the action from footer.jsp to different pages. But when i am including the footer.jsp to other jsp's, action is not working. Clicking on the command link refreshes the same page rather than going to the specified action. Please help.
Thanks
Neha

Hi,
this is because the footer gets included in the parent page, which means that the navigation is not from footer.jsp but from the parent jsp. Change the navigation cases you created for the footer.jsp to use a wildcard instead so that they work as global navigation cases. This solves your issue

"Errors on page" with simple JSF page

Hi
I wrote a very simple JSF page as shown below. It works as is with MyFaces. Now I tried to make it work with Sun RI as well.
Here's the problem: The page appears perfectly fine (it shows two columns of links). Only one single link works, though: the first one in the left column.
When I click on that first link, the action handler method ("userClick") is called and executed fine.
But when I click on any other link, the method is not called at all. All I get is an "error on page" message in the browser status bar. No log message on the command line or log file.
Am I doing something wrong? With MyFaces it works fine.

I don't think I need to show the backing bean with the userClick() method since the error is that this method is not even called (I added a system.out.println() to this method - which is never executed)
So the problem must be before
BTW I am using Sun RI 1.1.01 as shipped with the MyEclipseIDE extensions.
Thanks a lot for your very much appreciated help

The problem is that you have two forms. Put a single form.

Why does backbean's method be invoked when page navigation to other page

Hi, All
Why does backbean's method getBeans() be invoked
when current page(list.jsp) navigation to other page(edit.jsp)?
//client list.jsp
<h:dataTable id="items" value="#{userDelegate.beans}"
var="user" rowClasses="oddRow, evenRow" headerClass="tableHeader" >
//server backbean
public class CustomDelegate extends BaseDelegate{
public ListDataModel getBeans(){}
when list.jsp first initialize(first load), jsf invoke getBeans(), is right;
but when from list.jsp navigation to edit.jsp, jsf invoke getBeans() too!
what's the matter with it?

How are you invoking the navigation? With a simple h:outputLink which links to another page or with an h:commandLink/h:commandButton which naturally first invokes the backingbean?
If you're using h:outputLink, then this behaviour may not occur. You may review/redesign your JSF and bean logic.
If you're using UICommand link/button, then this is usual behaviour. (re)read the JSF lifecycle for an explanation. If you ONLY want to get the navigation case, then you can 1) replace the methodbinding from action or actionListener by just the navigation case string, or 2) add immediate="true" to the UICommand element.

Unable to view adf query panel in jsf page

hi i cannot view the Query > ADF Query Panel when i click the query button to load the page but i can see the page in design. i can only see the search with drop down arrow but cannot see other part of ADF Query Panel . i did this by 9.Expand the EmpDetails1 data control and expand the Named Criteria node below it. Select All Queriable Attributes and drag it into the new query.jsf page. Create it as a Query > ADF Query Panel.
