Navigation-Rule

I'm a newbie in JSF. I got some books and online tutorials. All the examples run fine, so I'm sure my basic configuration is fine.
Now I have the problem, thatI'm not able to do some navigation. I have the following files:
/usr/local/tomcat/webapps/fcms is my context, defined in Tomcat 5.5.7
Where I have this file in /usr/local/tomcat/webapps/fcms /admin

It instantiates fine the bean, because it displays the init-values. Here is the bean:
package applications.fcms.handlers;
import applications.fcms.ChapterRow;
import applications.fcms.ChapterBean;
public class NewChapter extends ChapterBean {
    int localid=0;
    public void setId(int v) {
     System.out.println("Setze ID: " + v);
        localid = v;
     if ( ( localid > 0 ) && (getDataSource() != null) ) {
         ChapterRow chapter = new ChapterRow(getDataSource());
            try {
         chapter.searchById(localid,true);
         chapter = chapter.next();
         if ( chapter != null ) {
          setId(chapter.getId());
          setButtonid(chapter.getButtonid());
          setName(chapter.getName());
          setValidfrom(chapter.getValidfrom());
          setValidto(chapter.getValidto());
          setCreationdate(chapter.getCreationdate());
          setDescription(chapter.getDescription());
          setSortname(chapter.getSortname());
          setWebsite(chapter.getWebsite());
          setText(chapter.getText());
         } catch (java.sql.SQLException sqle) {
          localid= 0;
         chapter.close();
    public int getId() {
     return this.localid;
    public NewChapter() {
        System.out.println("init bean");
     setButtonid(0);
     setName("");
     setValidfrom(new java.sql.Date((new java.util.Date()).getTime()));
     setValidto(getSomeYears());
     setCreationdate(getValidfrom());
     setDescription("");
     setSortname("");
     setWebsite("");
     setText("");
     setId(0);
    private java.sql.Date getSomeYears() {
     java.util.Calendar today = java.util.Calendar.getInstance();
     today.add(today.YEAR,+10);
     return (new java.sql.Date(today.getTimeInMillis()));
    String dataSource = null ;
    public void setDataSource(String v) {
     this.dataSource = v;
     System.out.println("Setze Dtasource: " + v);
    public String getDataSource() {
     return this.dataSource;
    public String saveChapter() {
        String msg="failure";
     System.out.println("SAVE CHAPTER");
        if ( (getDataSource() != null) && ( getWebsite() != null ) ) {
         ChapterRow chapter = new ChapterRow(getDataSource());
         chapter.setId(getId());
         chapter.setName(getName());
         chapter.setValidfrom(getValidfrom());
         chapter.setValidto(getValidto());
         chapter.setCreationdate(getCreationdate());
         chapter.setDescription(getDescription());
         chapter.setSortname(getSortname());
         chapter.setWebsite(getWebsite());
         chapter.setText(getText());
         if ( chapter.getId() == 0) {
          msg = chapter.insert();
         } else {
          msg= chapter.update();
         if (msg.toLowerCase().startsWith( "ok" ) ) msg = "success";
         chapter.close();
     return msg;
}and here the initial bean:

Navigation and Creating a navigation rule at runtime

Hi all,
How can I create a navigation rule at runtime?
I got all my pages (names and locations) stored in a database table.All my pages are jspx format.
I don't want to create navigation rules for each page, Instead I want to use the location stored in the database and create a navigation rule to navigate to.
I tried navigating using ServletRequest :
        ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();
        HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
        HttpServletRequest request = (HttpServletRequest)ectx.getRequest();
        request.getRequestDispatcher("/faces/Titles.jspx").forward(request,response);But it blows after the first call.
is it possible to create a navigation rule in a Bean or is there another way to call jspx pages from a Bean without loosing the session.
Can someone help me please.
thanks in advance,
Ahmad Esbita

Ahmad,
I don't know of any way to programatically create navigation cases at runtime. However, perhaps you could try creating a NavigationHandler decorator. Let's assume you have a function called "getViewIDforAction" that does the database lookup and returns the view ID for a given action code. You could do something like this:
package my.code;
import javax.faces.application.NavigationHandler;
import javax.faces.context.FacesContext;
public class MyNavigationManager extends NavigationHandler
   NavigationHandler _base;
   public NavigationManager (NavigationHandler base)
      super();
      _base = base;
   public void handleNavigation(FacesContext fc, String actionMethod, String actionName)
      String viewID = getViewIDforAction(actionName);
      if (viewID != null && ! "".equals(viewID))
         fc.getViewRoot().setViewId(viewID);
      else
         _base.handleNavigation(fc, actionMethod, actionName);
}You'll also need this in faces-config.xml:
<application>
<navigation-handler>my.code.MyNavigationManager</navigation-handler>
...any other stuff...
</application>Note: I haven't tested this or anything - just to give you an idea...

How can i add a navigation rule at the runtime of JSF?

Hello,
how can i add a navigation rule at the runtime of JSF. Maybe i should use the method "addNavigationRule()" in class "FacesConfig", but i do not know, how can i obtain the instance of class "FacesConfig". Can anybody help me?
Thank you very much!!!

Just curious: Why whould you want to add navigation Rules at run time. I believe the navigation rules should be set to begin with - "by s/w Architect Design".
Else you can always use Redirect / Forward.

JSF navigation rules sent me to different page, with same URL

Hello everybody,
Have a newbie question on JSF, if anyone can help me. I am using JSF for a web application, and i have a small problem.
If i define a navigation rule, from one page to another, and i am having a button that should send me to another page,
the browser URL remains the same, although the page content IS correctly changed.
Thanks,
Andrei

You're welcome.
Though I should have added that the advantage of the redirect after a POST request is that refreshing the request or navigating back and forward by browser history doesn't cause a re-submit of the POST request anymore. This way you avoid duplication of submitted data. This is called POST-redirect-GET pattern. Refreshing the request after a redirect (which is always a GET request) would only cause the redirect being refreshed, not the initiating POST request.
The disadvantage of a forward is less or more obvious: the URL remains the same and it is not really good for the user experience. If one copypasted the URL in a new window (a new GET request), one wouldn't see the forwarded page, but the originating page. That's why I would recommend to avoid navigation cases and just use the same page to postback the POST request to. For normal page-to-page navigation within a website, I would recommend just using outputlinks and not commandlinks with navigation cases. It's all better for the user experience.

SOS Problem with navigation rules

Hello,
I have been stuck for some time with a navigation problem: It seems my faces DD is read but the navigations rules are not. Unfortunately it does not give me any exception. The only thing that occurs is that the home page reloads itself instead of redirecting to the second page.
Here is my DD:

Hi,
I added a messages component to your home.jsp page and saw that the page produced validation errors (often the cause for failed navigation).
The problem is that the beans property minimumNote expects an int but gets a String. When you change the the type in the bean to String it works.
You will probably want to add a converter to the uicomponent to get the correct type. I'd be happy to tell you how, but I'm just starting with jsf ;-).

Adding custom navigation rules results in strange behavior

Hello,
We'd like to add navigation rules to our application. To avoid post-JHeadstart-generation-steps we created an extra faces-config-custom.xml file which contains the navigation rules. When adding this file to the web.xml and run the aplication we encounter strange behavior
- Errors are shown in duplicate
- 'Transaction completed' messages are not shown
Try adding the underneath faces-config-custom.xml to a standard HR demo project and you will get the same behavior.
(1) What is the reason of this strange behavior?
(2) How can we add custom navigation rules, without having to do post creation steps?

Leon,
When you perform a drag and drop operation, JDeveloper adds the following lines to the faces-config.xml:
<lifecycle>
<phase-listener>
Oracle.adf.controller.faces.lifecycle.ADFPhaselistener
</phase-listener>
</lifecycle>
However, JHeadstart uses its own subclass of ADFPhaselistener, and defines the lifecycle element in JhsCommon-beans.xml. Due to a bug in ADF, ADF does not look for the lifecycle element in other files than faces-config, and adds its own element in faces-config.xml If you remove these lines, everything works fine again.
To prevent this from happening again, you can move the following entry from JhsCommon-beans.xml to faces-config.xml:
<lifecycle> <phase-listener>oracle.jheadstart.controller.jsf.lifecycle.JhsADFPhaseListener</phase-listener>
</lifecycle>
And then make a custom template for JhsCommon-beans.vm where you remove this entry.

Access navigation rules programmatically?

Hello.
Is there any way to access the attributes of a navigation rule programmatically?
In Struts, I was accustomed to getting the URL of a forward that I had set up by doing something like:
<html:rewrite forward="myForwardName"...>on my JSP page, but I can't seem to find any equivalent of this functionality in JSF.
Also, I would like to be able to access the navigation rule attributes from Java code, too, particularly the "to-view-id" attribute, which is something I did in Struts with code like:
String path = mapping.findForward("myForwardName").getPath();I know that this isn't apples-to-apples, and that a global forward in Struts is not set up the same way as a navigation rule in JSF, but I'm hoping that there's some kindly JSF super-genius who can point me in the right direction. :-)
Thanks!
--Mike

Thanks, rei_nanto--that did shed a little light on the subject!
Now, unfortunately, I am not using the Sun reference implementation (we're using the IBM implementation), and so I don't have the ApplicationAssociate class you mentioned.
I went out and looked at the ApplicationAssociate and NavigationHandlerImpl classes in the RI jars, though, as you suggested, and I can see how it could be done.
The reason I'm looking for a way to get this information, especially the <to-view-id> information, is because I need to do a popup window from my JSF application page, and I would like not to hard-code the URL of the JSF page I want to appear in the popup.
Hence, if I could get the path out of <to-view-id> programatically, I wouldn't have to hard-code the path in my popup.
Any additional thoughts on the matter, given this additional information?
Thanks!

Change JSF navigation-rule not begin with "root"

Dear all,
I have a web application, call myApp, run in PC1. There is a navigation rule to control page1 jump to page2.
normally, after deploy and run my application, url for it is: [ http://{color:#0000ff}pc1:8080{color}/{color:#008000}myApp{color}/*{color:#ff6600}page1.jsf{color}* ], and click something in my page1, it will go to [ http://{color:#0000ff}pc1:8080{color}/{color:#008000}myApp{color}/*{color:#ff6600}page2.jsf{color}* ].
I have another machine, named PC2, and create a mapping and forward request to PC1. Therefore, if anyone type the url: [ http://*{color:#0000ff}pc2{color}*/subSection/{color:#008000}myApp{color}/{color:#ff6600}*page1.jsf*{color} ] , actuality, they are looking for [ http://{color:#0000ff}*pc1:8080*{color}/{color:#008000}myApp{color}/*{color:#ff6600}page1.jsf{color}* ].
Now, I have a problem is that, when people browse a page [ http://{color:#0000ff}*pc2*{color}/*{color:#ff00ff}subSection{color}*/{color:#008000}myApp{color}/*{color:#ff6600}page1.jsf{color}* ] and click something, it will go to another page [ http://{color:#0000ff}*pc2*{color}/{color:#008000}myApp{color}/*{color:#ff6600}page2.jsf{color}* ], not go to [ http://{color:#0000ff}*pc2*{color}/*{color:#ff00ff}subSection{color}*/{color:#008000}myApp{color}/*{color:#ff6600}page2.jsf{color}* ]. Therefore, it makes "404 Not Found" exception.
Does anyone help me?
Thank you
Kevin Tang.

I wanna to know can I modify my program, such as faces-config.xml, to fix my problem, or I need to modify my Tomcat setting ?I am suggesting you do not need to modify your program, but the configuration of whatever is doing the forwarding.

Dynamic Navigation mapping to Navigation Rules

I have a situation where I need to create a javascript "hover-over" nav. I'd also like to have them define the navigation rules in their faces config. My question is, how do I code the javascript "action" for each nav item so that it somehow maps to the navigation rules I defined in my faces config? Right now I'm just rendering all of my javascript in my JSP. In order to get this to work, do I have to create a JSF component? Will it fit into the architecture more cleanly if I do? Any hints? I'd like this to fit into the JSF programming model as much as possible.
Thanks,
Dave

I'm just kind of winging it at this point, basing my examples on some of the ones in Core JSF. I'm thinking my component will contain a string for the selected menu item and a collection of navigation items (display string/navigation key). Then there is the renderer for the component, followed by the Tag class and DTD. Does that sound like the right path? Since the nav is a glabal nav, I was thinking of reading in the structure from XML once, and not have all of the menu items in the JSP as child tags. I am still a bit confused as to how I will hook the action of the menu click to my backing bean action. Any help would be appreciated.

Problem with navigation-rules

Hello!!!
I'm using Jboss Jbpm with JSF and I want to navigate to other page when I fill a form and I send the data that I entered. I have declare the navigation-rules but it doesn't work and I don't know why.
In my faces-config.xml I've added the navigation-rules:
<managed-bean>
               <managed-bean-name>usuario</managed-bean-name>
               <managed-bean-class>com.miApp.UserBean</managed-bean-class>
               <managed-bean-scope>request</managed-bean-scope>
          </managed-bean>
     <navigation-rule>
               <from-view-id>/SolicitarAlta.xhtml</from-view-id>
               <navigation-case>
                    <from-action>#{usuario.registrar}</from-action>
                    <from-outcome>correcto</from-outcome>
                    <to-view-id>/results/correcto.jsp</to-view-id>
               </navigation-case>
     </navigation-rule>
     The UserBean has the method registrar:
public String registrar() {
       if(dni==null || nombre==null || apellidos==null || ocupacion==null || mail==null || tlf==null ||
password==null)
            return "campos-obligatorios";
       if ((mail.trim().length() < 3) ||      (mail.indexOf("@") == -1))
                      return "mail-incorrecto";
       else if(tlf.length()!=9)     return "telefono-incorrecto";
            else if(dni.length()!=8) {return "dni-incorrecto";}
       return "correcto";
     And with this line:
<h:commandButton type="submit" value="Enviar" action="#{usuario.registrar}"/>     the method registrar is executed and I know that this method returns the string "correcto" but ... This doesn't redirect me to the page correcto.jsp
I thought that maybe if SolicitarAlta was an xhtml file the correcto page should be also an .xhtml file. I changed it but it doesn't work.
Any ideas? Could it be that I have to add something more in the faces-config.xml & web.xml file???
Thx!

I found the solution to my problem but I don't really understand why it was not working. My problem was due to the use of command button with a render set to false. I just put them at true and all my navigation rules work!
If someone know why it was not working, I would be glad to know!

Navigation Rule for multiple Links

Hi,
I am using Eclipse & JSF.Now my problem is i having multiple links on a single JSF page. Suppose A,B & C.
Now A calling a page called AA.jsp through a backing bean.
Simmillarly, B calling a page called BB.jsp through a backing bean.
Simmillarly, C calling a page called CC.jsp through a backing bean.
I have defined a navigation rule also for that. But ,what happens is when A calls AA.jsp it gets redirected to CC.jsp.
I dont know how it is going.
My faces-config.xml is..
<navigation-rule>
         <display-name>
         Maintanance1</display-name>
         <from-view-id>

         </navigation-case>
    </navigation-rule>
   Plz suggest me...

You need to differentiate the navigation cases using from-outcome or from-action. You now say to JSF roughly: If the from view id is "maintenance.jsp" then you should go to "page1.jsp" AND "page2.jsp" AND "page3.jsp". This isn't going to work, you should tell JSF roughly: If the from view id is "maintenance.jsp" AND the outcome is "page1" then you should go to "page1.jsp" and so on. You can also just leave away the from-view-id and use from-outcome and/or from-action only, as I suggested before. This way you can go everything from everything: If the outcome is "page1" then you should go to "page1.jsp".
E.g.<h:commandLink action="page1">
<navigation-rule>
    <navigation-case>
        <from-outcome>page1</from-outcome>
        <to-view-id>page1.jsp</to-view-id>
    </navigation-case>
    <navigation-case>
        <from-outcome>page2</from-outcome>
        <to-view-id>page2.jsp</to-view-id>
    </navigation-case>
    ... (etc)
</navigation-rule>Edited by: BalusC on 28-apr-2009 11:20 (sorry, a typo in the navigation cases)

Navigation Rule not found in faces-config.xml file

Hi All,
I have a B2C custom Webshop application where in the startpage i have a client logo and when i click on that it will navigate to another page for that i have a header.xhtml page in that i have a code <h:link id="iLkL" outcome="toStartPage" value="#{i18n['main.ui.header.logo']}" styleClass="fw-header-logo"> but i was unable to find <Navigation-rule> of toStartPage which is mentioned in the outcome="toStartPage" in the faces-config.xml file. I have checked in the standard component also but didn't find anything. Please help me where can i find the toStartpage value.
Regards,
Rahul.

Hi Rahul,
As correctly mentioned by Steffen earlier, the navigation targets are maintained in the ui-repository.xml files (or navigation-rules.xml files) for each module. Since, you would like to see the definition of the target toStartPage (which is a target accessible and relevant throughout the application), it should be in the WEC main module's (wec/~/main/ui) ui-repository.xml file. Please note that sometimes, the targets are maintained in a file called navigation-rules.xml, which itself is then included into the ui-reppsitory.
Please let me know if you got what you need here.
Best Regards
Pranshu Agarwal

Re: problem getting navigation rules to work

Hello,
I am using EA4, JDK1.4.2, Tomcat 4.1.24, under Solaris 8.
When I click on the buttons, I always go back to the original page (EmailLookup.jsp) rather than following the navigation rules.
I print to a file when invoke in Action is called, in my classes, so I know that when I click on the search or clear buttons that the correct action is being ran, through my properties.
I don't know why this is not working, and would appreciate some help.
<navigation-rule>
<from-tree-id>/EmailLookup.jsp</from-tree-id>
<navigation-case>
<from-outcome>success</from-outcome>
<from-action-ref>EmailSearchModel.searchAction</from-action-ref>
<to-tree-id>/response.jsp</to-tree-id>
</navigation-case>
<navigation-case>
<from-outcome>reset</from-outcome>
<from-action-ref>EmailSearchModel.resetAction</from-action-ref>

</navigation-case>

<h:command_button label="Search"
commandName="submit" actionRef="EmailSearchModel.searchAction" />
<h:command_button label="Clear"
commandName="reset" actionRef="EmailSearchModel.resetAction" />
Thank you.

Problem solved, it ended up being that the directory name was the same as the first JSP page, it appears.
My directory was EmailLookup, and since the JSP page was EmailLookup.jsp, and EmailLookup was referenced in the faces-config.xml file, there was confusion.
I changed the directory name to DirectorySearch, and it works fine.

How to add the ability to put EL expressions in Navigation Rules

I had a need to dynamically determine what page to return to in a JSF application. There has to be an easier way, but here's how I wanted to do it. I wanted to put an EL expression in my <to-view-id> nav rules in the JSF config file (e.g. faces-config.xml). This isn't allowed. So I built my own custom ViewHandler to do it.
1) Define the ViewHandler in faces-config.xml:
     <application>
          <view-handler>com.msd.tts.pluggable.MyDynamicViewHandler</view-handler>
     </application>2) Create the class:
package com.msd.tts.pluggable;
import java.io.IOException;
import java.util.Locale;
import javax.faces.*;
import javax.faces.application.ViewHandler;
import javax.faces.component.UIViewRoot;
import javax.faces.context.*;
import javax.faces.el.ValueBinding;
import com.sun.faces.util.Util;
* Adds ability to put EL expressions in the <to-view-id> Navigation Rules in JSF
* configuration file (faces-config.xml).
* @author          Craig Peters
* @version          1.0
public class MyDynamicViewHandler extends ViewHandler {
     * The original handler we are customizing.
    private ViewHandler prevHandler = null;
    /** Creates a new instance of MappingViewHandler. By including
     * a parameter of the same type, we encourage the JSF framework
     * to pass a reference of the previously used ViewHandler. This way
     * we can use all the previous functionality and override only the
     * method we are interested in (in this case, the getActionURL() method).
     public MyDynamicViewHandler(ViewHandler prevHandler) {
          this.prevHandler = prevHandler;
     @Override
     public String getActionURL(FacesContext context, String viewId) {
          return prevHandler.getActionURL(context, viewId);
     @Override
     public Locale calculateLocale(FacesContext context) {
          return prevHandler.calculateLocale(context);
     @Override
     public String calculateRenderKitId(FacesContext context) {
          return prevHandler.calculateRenderKitId(context);
     @Override
     public UIViewRoot createView(FacesContext context, String viewId) {
          return prevHandler.createView(context, viewId);
     @Override
     public String getResourceURL(FacesContext context, String path) {
          return prevHandler.getResourceURL(context, path);
     @Override
     public void renderView(FacesContext context, UIViewRoot viewToRender)
               throws IOException, FacesException {
          String result = viewToRender.getViewId();
          if (Util.isVBExpression(viewToRender.getViewId())) {
               ValueBinding vb = context.getApplication().createValueBinding(viewToRender.getViewId());
               result = vb.getValue(context).toString();
          if (result.charAt(0) != '/')
               throw new IllegalArgumentException("Illegal view ID " + result + ". The ID must begin with '/'");
          viewToRender.setViewId(result);
          prevHandler.renderView(context, viewToRender);
     @Override
     public UIViewRoot restoreView(FacesContext context, String viewId) {
          return prevHandler.restoreView(context, viewId);
     @Override
     public void writeState(FacesContext context) throws IOException {
          prevHandler.writeState(context);
}3) Use EL in navigation rules:
     <navigation-rule>
          <from-view-id>/CommonForm.jsp</from-view-id>
          <navigation-case>
               <to-view-id>#{bean.caller}</to-view-id>
          </navigation-case>
     </navigation-rule>The "bean.caller" method will have saved the page to go back to.
Comments are welcome. I just didn't see any other way to dynamically go back to an arbitrary page.
Thanks.

Comments are welcome.Nice stuff. But that means that navigation is hardwired in the backing bean instead of faces-config.xml. Forget this comment if you've maintained a propertiesfile/configurationfile for that.
I just didn't see any other way to dynamically go back to an arbitrary page.You can declare more than one from-outcome and/or from-action for one from-view-id.

Alternative of Navigation-Rule.

Let us say I have a LoginBean java (for login web screen) and a MainBean java (for main web screen). In the JSP file I will call the LoginBean method to launch the screen with components dynamically using the following lines:
<f:view>
<h:form id="Login">
<table height="100%" width="100%" border="0">
<tr>
<td align="center" valign="middle">
<af:panelGroup binding="#{LoginBean.loginPanel}" />
</td>
</tr>
</table>
</h:form>
</f:view>
Right now I am using navigation-rule to move to the main screen reading the MainBean from the main screen JSP file. Can I create an instance of the main screen from the LoginBean? Here is an example of creating an instance:
main = new MainBean(this, "APPLICATION NAME");
Any idea?

The <from-view-id> is optional. Just remove them.
By the way, I would rather use plain vanilla links (<h:outputLink> or just <a>) for plain navigation. Navigation by POST isn't always a good idea.
