Passing Request Parameters to Non JSF Page
I want to pass request parameters from a JSF page (Page1.jsp) to a non JSF page (paramTest.jsp) and am having trouble.
The parameters are 'null' in the non JSF page.
Here is code (in Page1.java) that is called when 'button1' is clicked in Page1.jsp (modified from JSF, Bergsten p.167):
public String button1_action() {
FacesContext context = javax.faces.context.FacesContext.getCurrentInstance();
ExternalContext ec = context.getExternalContext();
try {
ec.redirect("http://xxx/paramTest.jsp");
} catch (Exception e) {
// print exception information in the server log
log("Exception occurred when redirecting page", e);
error("Trouble redirecting page");
return null;
context.responseComplete();
return "success";
}Here is Page1.jsp code: <?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="1.2" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:jsp="http://java.sun.com/JSP/Page">

Hi,
I dont see any parameters that you are trying to pass in the below code.
public String button1_action() {
FacesContext context = javax.faces.context.FacesContext.getCurrentInstance();
ExternalContext ec = context.getExternalContext();
try {
ec.redirect("http://xxx/paramTest.jsp");
} catch (Exception e) {
// print exception information in the server log
log("Exception occurred when redirecting page", e);
error("Trouble redirecting page");
return null;
context.responseComplete();
return "success";
}

JSF Page -- Backing Bean -- Non-JSF Page ...
Hi
I have a JSF page where the user enters data and submits by clicking on the Submit button. My backing bean then takes the data and processes it. After successful processing, I want to direct the user to a non-JSF page.
What is the best way of achieving this?
ThanksI am doing the following to get the desired effect now:
FacesContext ctx = FacesContext.getCurrentInstance();
ExternalContext ectx = ctx.getExternalContext();
HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
String nextUrl = "....";
response.sendRedirect(nextUrl);
Is there a better way? -
Use commandLink to forward non-jsf page cause other commandLink invalidate
Hi :
I use commandLink to forward to non jsf page , after click the link , it worked , success to 1.jsp. Then I click another link , the other commandLink doesn't work.
any one have the same problem ?
JSF page:
<h:commandLink action="#{MenuHandler.go}">
<h:outputText value="process" />
<f:param value="1.jsp" name="forward" />
</h:commandLink>
MenuHandler.java
public static String go() {
HttpServletRequest req = getRequest();
String forward = req.getParameter("forward");
getExternalContext().redirect(forward);
FacesContext.getCurrentInstance().responseComplete();
return "success";
}ps:there is one <h:form/> in my jsf page and I use:
jdk1.5.0
jsf-1_1
Tomcat-5.0.28to supplement:
I found something strange:
The JSF page I used is for menu purpose.
So there is a <BASE target="mainFrame"> tag in my JSF page.
If I mark it . Then other commandLink can work ~~
Because the page is a menu page , so I can't mark the <BASE target="mainFrame"> -
Newbie: what is the equivalent of passing request parameters?
Hi-
I am new to JSF. I have read many tutorials and articles. I still don't get one concept about passing parameters. Note: I don't want to store stuff in the session unless I have to.
Let's say I have a page with a list of users. I layout the page with a panelGrid. Each row of the table has the first and last name of the user. If a user clicks on the name of a user on the user list, it should go to the user profile page. The backing bean for the user list page will be the UserListBean. It has a method called getUsers() that returns a List of User objects.
For the View User page, I have a ViewUserBean. The ViewUserBean retrieve the entire profile for that user.
How do I pass the user ID to the ViewUserBean? In struts, I would pass it as a request parameter (I would manually write the link URL with the userID). I know I can use the request like that in JSF, but that seems ugly. I looked at the code of the J2EE bookstore tutorial and it does a funky thing with all sorts of data stored in the session.
What is the best way to request a page and "pass in" a userID?
Thanks for your help.
AdamI have a case on my current project very similar to your case. What you want, very simply, is an easy way to allow faces to handle URLs like http://www.domain.com/showUserDetails?userId=50
The natural trouble is that when loading the page, there is no action to use to prefetch the User object based on the Request Parameters in JSF.
All the solutions above either rely on the session or they are exceedingly complex. This case is actually very easy to do and is very straight forward using Managed Properties and a Request Scope bean...
Here is the rather straight forward solution I used...
First, make a "ShowUserDetailsBean" which represents the "logic" for this page.
public class ShowUserDetailsBean
/** Will point to the actual user service after dependency injection*/
private UserService userService;
/** Will hold the userId from the HTTP Request Parameters*/
private String userId;
/** Will hold a lazy loaded copy of the User object matching userId*/
private User user;
public void setUserService(UserService userService) {
this.userService = userService; //dependecy injection
public void setUserId(String userId) {
this.userId = userId; //dependency injection
/** Lazy loads the User object matching the UserId */
public User getUser() {
//Trap the case where the URL has no userId
if (userId == null) return null;
if (user == null) {
user = userService.getUser(userId); //Lazy Load
return user;
}Next, configure the managed properties in faces-config.xml
<faces-config xmlns="http://java.sun.com/JSF/Configuration">
<managed-bean>
<managed-bean-name>userService</managed-bean-name>
<managed-bean-class>foo.UserServiceImpl</managed-bean-class>
<managed-bean-scope>application</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>showUserDetails</managed-bean-name>
<managed-bean-class>foo.ShowUserDetailsBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>userService</property-name>
<property-class>foo.UserService</property-class>
<value>#{userService}</value>
</managed-property>
<managed-property>
<property-name>userId</property-name>
<property-class>java.lang.String</property-class>
<value>#{param.userId}</value>
</managed-property>
</managed-bean>Finally, you just make your webpage as you normally would...
<h:outputText value="#{showUserDetails.user.userId}"/>
<h:outputText value="#{showUserDetails.user.firstName}"/>
<h:outputText value="#{showUserDetails.user.lastName}"/>
Now you're ready to test, so you visit the page
http://www.domain.com/showUserDetails?userId=50
And your user details with userId=50 appears!
It's just that simple!
Regards,
Doug
Caveat: I haven't added any sample logic to handle cases where you visit:
http://www.domain.com/showUserDetails
without specifying a userId. I suggest you add some basic logic to your page to handle this case more gracefully. -
Passing URL parameters to PL/SQL Pages
Hi,
I want to pass parameters from url to the PL/SQL page . How is this possible?
http://myserver/pls/portal/url/PAGE/page_group/page/testplsqlpage?course_ref=##COURSE_ID##&staff_ref=##STAFF_ID##
I will to received course_ref and staff_ref in the PL/SQL page and pass the values to SQL query so that its filtered.
Can pls anyone guide me? If there is any alternate way or there is sample code pls let me know
Many Thanks
GaneshHi Mick,
Thanks for your reply. However my problem is still not resolved.
I have created a Omniportlet with lists the staff details. When I click on the staff link I am passing to parameters as follows
http://servername/pls/portal/url/PAGE/CCM_MIS_PORTAL/TUTOR_HOME/Course_Info?Param1=10017031/M2523&Param2=001434
on the receving page I have a omni portlet which must receive these 2 parameters and pass it on to the query and filter the results.
On the received page I have created 2 page parameters (Param1 and Param2)
I have assigned these 2 paramaters to the portlet paramers through page parameters' section
on the omni portlet in the query I have created 2 bind variables (p1, p2) and the default value of the bind variable is set using ##Param1## and ##Param2## so the received values from page is passed to to bind variable and hence to the query.
However the omni portlet is not received the parameters and I can not figure out whats wrong?
Is there any problem with my URL (guide says I should use relative URL)
Please help -

JSF and links with parameters to restore jsf page state
Hi,
I've been developing a forum using JSF. It's going to be something similar to the one we are just using.
If a user, while browsing forum, find something interesting he should have a possiblity to copy URL form his browser and give it to his friend.
The URL should contain all necesary parameters to restore a same view (a subpage of a forum etc) a first user had. What's best approach to do it ?
Say, I have a few AJAX components on a forum page, how can I restore their states ? What's even more interesting how can I generate add parameters to URL in a browser ?
I've found a good solution for my problem:
[http://ocpsoft.com/prettyfaces/]
"PrettyFaces is an OpenSource extension with enhanced support for +JavaServer
Faces+ - JSF 1.1, 1.2 and 2.0 - enabling creation of bookmark-able,
pretty URLs. PrettyFaces solves the "RESTful URL" problem elegantly,
including features such as: page-load actions, seamless integration with
faces navigation, dynamic view-id assignment, managed parameter
parsing, and configuration-free compatibility with other web frameworks"best approach would be http://www.phpbb.com/ :-)
seems crazy going to all that hassel, phpbb is so simple, infact a lot of jsf forums such as primefaces [http://primefaces.prime.com.tr/forum/] use phpbb, as you can have your fourm up and running in no time

Forwarding requests on to non-java pages from servlet.
I have designed a web application using a form of single controller pattern.
I have a number of JSPs.
Each of these JSP's has a form element which if submitted got to a single servlet (Controller)which then forwards on the request to a different class based on the paramter passed. For example this form would call the SubmitFeedback class.
<form name="feedbackform" method="post" action="<%=request.getContextPath()%>/controller">
<input type="hidden" name="action" value="SubmitFeedback"/>
<input type="hidden" name="page" value="feedback.jsp">
<tr><td><input type="submit" name="go" value="Go"/></td></tr>
</table>
</form>After the class has done its processing it returns what page to go next to the Controller class and this forwards the request on. to the next jsp
String nextPage = createAction(request.getParameter(PARAM_ACTION)).handleRequest(this,request, response, request.getParameter(PARAM_PAGE));
request.getRequestDispatcher(nextPage).forward(request, response);
return;This is all fine but now I have a sitation where after the user submits the form I want do some processing then forward them onto another page which is not part of my system, nor java. But the RequestDispatcher is only for the current Context within a Servlet Container.
Could someone explain how I do this, what am Im missing please.i am not a JavaScript expert, so I can't be sure this is everything, but:
1) The javascript has to be put inside a <script></script> block (you also had an extra close bracket):
<script type="text/javascript">
<!--
function validateAccept() {
toReturn=true;
if (form.accept.checked==false) {
alert("You must select at least one checkbox to search");
toReturn=false;
return toReturn;
//-->
</script>The script block is usually put in the head section also, but that is not necessary.
2) I would call this function from the onsubit event of the form rather than the onclick of the submit button
<form name="form" action="..." method="post" onsubmit="return validateAccept();">
//...3) You will need to identify the form that you want to use inside the function. Just using the name form won't work, it has to be retrieved from a certain context. The easiest thing is to pass it in as a parameter:
<script type="text/javascript">
<!--
function validateAccept(form) {
<form name="form" action="..." method="post" onsubmit="return validateAccept(this);"> -
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

Actions/submitting non JSF forms to JSF pages
Ok, I am new to JSF so bear with me,
I am trying to execute some logic BEFORE displaying a JSP/JSF page - a simple example of this is checking if user is logged in, or getting data for the page based on parameters passed in from a non-JSF page (or on URL line), or deciding which page to display, etc. In other words similar to struts action.
Seems basic but I cant figure out how to do it without placing logic into JSPs. All examples I see seem to require a submit from a JSF page to get to the controller logic. What am I missing?
Thanks.I decide the struggling is a sheer waste of time and hurts future reusability and maintainability.
Write a set of JSF embedded JSPs from scratch.

Passing parameters from one OAF page to another OAF PAge
Hello
I was wondering, if there is a possibility of passing request parameters from one page to another page in EBS ( E-Business Suite).
I tried using the following
a) PageContext.putParamater ( "MyParamater", "ParamaterValue")
b) I addded the above line of code by extending an page controller of the OAF page and personalized the page
When I am trying to retrieve the value by getParameter() in the next page. I am also unable to get access to the parameter in the next page.
I am trying the above code while trying to create expenses in I-Expense module...I would like to pass the ReportHeaderId from one page to another page for customization purposes. I Am not able to get ReportHeaderId in the ReviewPAge...There are no Business Objects in the Review page...hence trying the putParameter idea.
Any help will be highly appreciated
Thank YouWhat is the source of the parameter? If the source is a VO, you can use the method I have specified in my previous post regarding updating the button properties. For example, you can include the param in the destination URL of the button as such:
OA.jsp?page=/xyz/oracle/apps/.../myPG&retainAM=Y&addBreadCrumb=Y&myParam={@ParamSource}
where ParamSource is an attribute from a VO.
You can get this value via oapagecontext.getParameter()
Can you please give details as to the source of your params (param-1, param-2, etc.). This will help in providing you suggestions.

What is the best way to Process non-JSF request??
I am engaged in new project using JSF.
We came across the serious problem that there is no-way
to let JSF execute action method of managed bean at the
first request.
That is because, JSF gets method binding information only
from pre-displayed UIComponent, it seems impossible to
let JSF know about the method binding info when they receive
the request from external system, or from non-JSF pages i n the
same system.
I get to two ways to solve this problem.
1. develop a custom-servlet
The tasks of the custom servlet is,
- receive a request from external system or non-JSF pages.
- get managed bean and execute it's action method.
- get next page info
- dispatch to next page through FacesServlet
2. use bridge-JSF page as a intermediation
This is kind of last resort.
As I described above, JSF can get method binding info, only
from components of pre-displayed pages.
So, I use bridge -JSF page to let it work as a intermediation.
It displays nothing, just click the commandbutton automatica
lly(by JavaScript).
Of-cource, I prefer 1 to 2.
Codes below are custom servlet sample , I made.
Pls let me know if it's ok or not.
thanks
public class FESFacesServlet extends HttpServlet{
public void doPost(HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
/* init process */
LifecycleFactory lFactory = (LifecycleFactory)
FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
Lifecycle lifecycle = lFactory
.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
FacesContextFactory fcFactory = (FacesContextFactory)
FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
FacesContext facesContext = fcFactory.getFacesContext(getServletContext(), request, response,lifecycle);
Application application = facesContext.getApplication();
/* set from-view-id */
ViewHandler viewHandler = application.getViewHandler();
String viewId = request.getParameter("fromviewid");
UIViewRoot view = viewHandler.createView(facesContext, viewId);
facesContext.setViewRoot(view);
/* find managed bean and execute it's action method */
ManagedBeanBase managedBean = (ManagedBeanBase)application.getVariableResolver().
resolveVariable(facesContext, request.getParameter("command"));
String outCome = managedBean.start();
/* look for next page info */
NavigationHandler navigationHandler = application.getNavigationHandler();
navigationHandler.handleNavigation(facesContext, null, outCome);
/* dispatch to next page throw FacesServlet */
facesContext.getExternalContext().dispatch("/faces" + facesContext.getViewRoot().getViewId());
facesContext.release();
public void doGet(HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
this.doPost(request,response);
-the common approach is kind of like your number 2)
but you dont need a commandButton
just have your first page redirect to your start page
e.g.
index.html
<html>
<head>
<!�redirect to startPage -->
<meta http-equiv="Refresh" content= "0; URL=index.faces"/>
<title>Start Web Application</title>
</head>
<body>
<p>Please wait for the web application to start.</p>
</body>
</html> -
How to send a request parameter to a dialog pages with jsf
I'm using the dialog framework of oracle, java server faces.......
I need to open a url on a dialog page(request scope), and I must to pass request parameters. I put <f:param> objects inside the commandLink who I click.....
If the page is not dialog, it woks fine, but when I put in a dialog way.... nothing work
=[
anyone know what I have to do?
thanksHi, I suppose you have already seen the ADF DIalog Framework, isn't it?
I think there tells how to pass parameter
A workaround is to save them in your session and then get them back and remove -
HOWTO: command_button, action and request parameters HOWTO
Starting from carDetail.jsp example:
Click of button:
<h:command_button
action="#{carstore.storeFrontLuxuryPressed}"
value="#{bundle.moreButton}" >
</h:command_button>
Method Invoked:
public String storeFrontLuxuryPressed() {
setCurrentModelName("Luxury");
return "carDetail";
Navigation case "carDetail" maps to:
<navigation-rule>
<from-view-id>/storeFront.jsp</from-view-id>
<navigation-case>
<description>
Any action that returns "carDetail" on storeFront.jsp should
cause navigation to carDetail.jsp
</description>
<from-outcome>carDetail</from-outcome>
<to-view-id>/carDetail.jsp</to-view-id>
</navigation-case>
</navigation-rule>
So I imagine that a forward is done to carDetail.jsp
At this point I want to daviate from the sample. I would like to pass request parameters to carDetail.jsp
like:
carDetail.jsp?mode=create&date=25-Dec-2003
I want my managed bean in carDetail.jsp to get populated from request scope. The managed bean in config looks something like this:
<managed-bean>
<description>this is for item test bean.</description>
<managed-bean-name>PageParams </managed-bean-name>
<managed-bean-class> com.a.PageParams</managed-bean-class>
<managed-bean-scope> request </managed-bean-scope>
<managed-property>
<property-name>mode</property-name>
<value>#{requestScope.mode}</value>
</managed-property>
<managed-property>
<property-name>date</property-name>
<value>#{requestScope.date}</value>
</managed-property>
</managed-bean>
How should I code the following method to pass the request parameters to the next page:
public String storeFrontLuxuryPressed() {
setCurrentModelName("Luxury");
//Can I do anything here to help navigation system to pass additional request parameters to
//the carDetail.jsp page
return "carDetail";
Please help as I have many pages that have command_button and control leads to other pages that take request parameters to initialize and set themselves up. And I can't understand how to make the two concepts work together?
Thanks,
VinayThx hunangdp
your solution of using <f:parameter> is perfect #in case# <h:command_button> is not nested inside <h:data_table> , otherwise the request parameter passed will always show the value of the 1st row , not the clicked row .
consider the following :
<h:data_table var="item" value="#{shoppingCartBean.shoppingItems}" >
<h:column>
<h:command_link value="#{item.productId}" action="product" id="productAction">
<h:output_text value="#{item.productName}"/>
<f:parameter name="productId" value="#{item.productId}"/>
</h:command_link>
</h:column>
</h:data_table>
in this case using the following at the back end :
FacesContext fc = FacesContext.getCurrentInstance();
java.util.Map requestParameter = fc.getExternalContext().getRequestParameterMap();
String value = requestParameter.get("productId");
will return the value of the 1st row ..
so if, instead I consider adding an action listener which set the request attribute "productId" to the command_link value , this will work , but I have to get the value from request attribute not the request parameter ==> :
<h:data_table var="item" value="#{shoppingCartBean.shoppingItems}"
rowClasses="InnerTable">
<h:column>
<h:command_link value="#{item.productId}" action="product" id="productAction">
<h:output_text value="#{item.productName}"/>
<f:action_listener type="mybean.Listener"/-->
</h:command_link>
</h:column>
</h:data_table>
and mybean.listener ==> :
String id = (String) ((UICommand) event.getComponent()).getValue();
HttpServletRequest request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
request.setAttribute("productId", id);
any comments.. ?
