Redirect from JSF backing bean to another application

Hi,
I need to open another (non-JSF) application in a new window from the backing bean of my JSF application.
My JSF application is in frames. - heading, menu, content.
I've a commandlink in the menu frame.
I tried with
FacesContext.getCurrentInstance().getExternalContext().redirect(loginUrl);
This is opening in the menu frame itself.
I tried using target="new" , but no result.
I also need to pass the userId to the external application.
Any ideas?
~Thanks.

Thanks.
Yes, GET works. I used a <h:outputLink and used target="new" and
window.open("url?userId=someId")
But i donot want to pass userid in GET in the url, since that is a sensitive information.
Please let me know if there's any other way.
Thanks,

Open URL in a new browser from a JSF backing bean

I want to use commandButton action in jsf to launch a new browser instead of using commandLink.
How do you launch url in a new browser window by firing up a method in backing bean?
So far I am able to launch a URL within the same browser window. Here is my code:
In jsp file:
<h:commandButton rendered="#{openDataList.valueModifiable}" value="link" action="#{openDataList.link}" />
In backing bean:
public void link()
     try{
     FacesContext faces = FacesContext.getCurrentInstance();
     faces.responseComplete();
     ExternalContext context = faces.getExternalContext();
     context.redirect("http://www....");      }
     catch(java.io.IOException e)
...

with a commandButton i dont belive you can
well there are ways you can use javascript window.open
or you can use a commanLink ans set the target
but from my understanding there is no way to open a new browser from the backing beans ( this is because this is a client function and your backing beans are on the sever )

ADF-BC/JSF How to display acustom error message from a backing bean

Hi all
Can anybody provide an example of how to manipulate the list of error messages from a JSF backing bean.
In my code I use a different navigation case and this directs the user to the page displaying the error message but I am sure that there must be a more elegant way.
Thanks in advance
Thanassis

Thanks Kris
I think you 've put me on the right track here, it's just that in my case what I really want to do is prevent my users from editing records not belonging to their own group. This is done via a selectOne table component and then the backing bean code tests if the value #{row.UserGroup} matches the #{bindings.LoggedOnUserGroup.inputValue}. If the values are equal then the beans returns the navigation case to the edit page. Otherwise it returns the navigation case for the "cannot edit" page.
So what I am thinking is to return null and somehow raise the right kind of exception in order to display the error in the af:messages tag.

The difference in calling an application module from a backing bean

Hello everybody!
I don't understand exactly, where is the difference in calling an application module from a backing bean in the following ways.
Example 1
FacesContext context = FacesContext.getCurrentInstance();
ValueBinding vb = context.getApplication().createValueBinding("#{data}");
BindingContext bc = (BindingContext)vb.getValue(context);
DCDataControl dc = bc.findDataControl("AppModuleDataControl");
AppModuleImpl appModule = (AppModuleImpl)dc.getDataProvider();Example 2
String amDef = "model.services.AppModule";
String config = "AppModuleLocal";
AppModuleImpl appModule = (AppModuleImpl)Configuration.createRootApplicationModule(amDef, config);Example 3 (the same like Example 1???)
String EL = "#{data.AppModuleDataControl.dataProvider}";
FacesContext fc = FacesContext.getCurrentInstance();
ValueBinding vb = fc.getApplication().createValueBinding(EL);
AppModuleImpl appModule = (AppModuleImpl)vb.getValue(fc);Please can anybody explain, what the three examples do? Which example is preferred to call an application-module-method from a backing bean?
Thanks and regards
Majo
Edit: I am using ADF BC 10g in JDev10 :)

Hi :)
>
This could work, but can you describe the use case for which you need to get the ApplicationModule?
Maybe we can find a better way to implement your functionality.
>
Sure, i know a lot of better ways to implement the same functionality too but its a huge project, its not my code and we have no time to reimplement this functions ;)
Frank, i don't understand the first line of your code.
DCBindingContainer bindings = ... resolve #{bindings}Where do i get the bindingContainer, if I don't have the "JSFUtils"- or "ADFUtils"-classes?
Regards
Majo
Edit:
Sorry, i have answer, before i think about it ;)
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
DCBindingContainer bindings = (DCBindingContainer)app.getVariableResolver().resolveVariable(context, "bindings");
BindingContext bctx = bindings.getBindingContext();
DCDataControl dc = bctx.findDataControl("AppModuleDataControl");
AppModuleImpl am = (AppModuleImpl)dc.getDataProvider();or in my backing bean, when i add the property to the faces-config.xml
DCBindingContainer bindings = this.getBindings();
BindingContext bctx = bindings.getBindingContext();
DCDataControl dc = bctx.findDataControl("AppModuleDataControl");
AppModuleImpl am = (AppModuleImpl)dc.getDataProvider();Is this right?

Accessing a JSF element from a back bean method

Hi,
short question, can I access the JSF element from a back bean method?
So, for example, if I have the following JSF code:
<h:panelGroup id="test1" rendered="#{bean.someMethod}">...</h:panelGroup>
<h:panelGroup id="test2" rendered="#{bean.someMethod}">...</h:panelGroup>
<h:panelGroup id="test3" rendered="#{bean.someMethod}">...</h:panelGroup>
Can I found out in some way, which element (esp. which ID) calls the someMethod-method?
Kind regards
Matthias

There are more possibilities as well. If you depend it on for example the User's rights/groups, then you can also do for example:
rendered="#{user.admin}" // getter = public boolean isAdmin()
rendered="#{user.groupName == 'admin'}" // getter = public String getGroupName()
rendered="#{user.groupId > 1}" // getter = public int getGroupId()
rendered="#{fn:contains(user.groups, 'admin')}" // getter = public String[] getGroups() or public List<String> getGroups()
etc..I think it's after all just a matter of learning about the capabilities of EL a bit more.

How can fill javascript array from list in jsf backing bean

Hello
i have an array in javascript and i want to fill in from the list which is coming from the backing bean how can i do that.
Regards

Hi,
using the ExtendedRenderkitService class you can send JavaScript calls from a managed bean to the client. So in your case you call a client side javaScript method and pass the array information as an argument. The way you pass the array data is up to you. You may just pass a character delimited list, or use JSON object notation in case the list shows objects. Note that this is for JDeveloper 11.In 10.1.3 there is no server side JavaScript API. Here you would have to add the JavaScript to the page when rendering it.

WebSphere Custering and JSF Backing Beans

Hello All,
Can anyone enlighten me on exactly how backing bean state is maintained by JSF?
In what scope does JSF store the backing beans? (session perhaps)
Does it make sense to use JSF without stateful backing beans?
What would happen if a client post did not find its corresponding backing bean on the application server calling it?
Background:
In a clustered WebSphere Server environment, a client post may be directed to any one of the machines in the cluster. If the client post gets directed to a machine other then the machine that originally sent the client a response, the page will not find the corresponding page beans.
It is possible to serialize session beans in WebSphere and have each machine share its memory with all the boxes in the cluster. However, this practice is not permitted in some environments.
Any thoughts? Thanks in advance.

I am probably not an expert on the subject. But here are some thoughts:
1. A backing bean can have (application, session, request or None) as a scope.
Less app or session scope beans the better (from server perspective). But
There are practical reasons why you would want to use them in many cases.
2. JSF supports Client State Saving mode. But keep in mind the overhead
Involved (serialization, de-serialization, bandwidth,...).
3. You probably need to read about WebSphere load balancing capability. From
what I know it is somehow sophisticated. People typically use session affinity
to force requests initiated by same session to be served by the same app
server (enforced by network, hardware/software tools available to do so,...). Of
course with failover mechanism to ensure high availability.
Hope that helps!

Error when I call a method of AppModule from a backing bean.

I use Jdeveloper 10.1.3.0.3 EA.
In my application I have created ApplModule and UsrView(for my table USR).
I have a login page (login.jsp and the backing login.java) with 2 fields userName and password and an ADF Faces Core command button (cmdCheckPass) and the method cmdCheckPass _action() for the click event .
The problem is that I cant call method testPassword(userName, password) which is written in AppModule. (I get error:
javax.faces.FacesException: #{backing_login.cmdCheckPass_action}: javax.faces.el.EvaluationException: java.lang.NullPointerException) from line:
answer = app.testPass(st1,st2);
The code is as follows:
public String cmdCheckPass_action() {
String answer="";
String mes = "";
String st1=this.getInputText1().getValue().toString();
String st2=this.getInputText2().getValue().toString();
AppModuleImpl app = new AppModuleImpl();
answer = app.testPass(st1,st2);
if (answer == "OK") {
return "toMain";
} else {
answer = "";
mes="Invalid username, password !!!";
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(mes));
return answer;}
I dont know if theoretically is right to call, from a backing bean, a custom method of AppModule.
Can I have any help on this?
Thanks in advance,
Panos

Some quick ideas:
Is the clip the same NTSC/PAL standard as the project you are importing it to?
Have you tried to rename the offending clip (do NOT rename any clips inside the iMovie /Media folder!!).
How much free space do you have on the iMovie project volume -- what is the size of the imported clip?

JSF Backing bean / JSP interaction questions

A few questions about JSF beans and JSP page interactions. Bear in mind that I'm new to both JSP and JSF, so a solution that might be obvious to the rest of the world may be new to me.
1. Can I pass a parameter to the backing bean method from an "action" attribute:
<h:commandLink action="#{TableData.SortRec}">
<h:outputText value="#{msgs.selectedHeader}"/>
</h:commandLink>
I'd like to call the same method from several controls, but pass it a parameter to determine which field to sort on.
2) Is there a way for a backing bean method to determine which control invoked it?
3) Is there a way to access JSF backing bean methods from JSP tags. I'd like to do some conditional page assembly based on a JSF bean property... JSF doesn't appear to have a conditional like JSP's <c:if>, but I could use JSP's if it could access the JSF bean.

Could you pl tell me how to pass parameter thru CommandButton
I have the following situation
1) greetingList.faces which list the Ids & greeting Text
Id Text
1 Hello World
2 Hello World
2) Pl note Ids are h:commandLink. A click on the Id will render greetingForm.faces with data pertaining to that Id and with Update h:CommandButton
3) When i click Update button it results in the following error
javax.faces.FacesException: Error calling action method of component with id greetingForm:_id4
Caused by: javax.faces.el.EvaluationException: Exception while invoking expression #{greetingForm.update}
Caused by: java.lang.NullPointerException
So i verified with h:message that Id is passed as Null when click on Update button. I also checked greetingForm.faces has a not null value by printing <h:outputText value="#{greetingForm.message.id}"/>
So i guess the Id value is overwriteen with null. Also i have defined Id as property in managed bean
<managed-bean-name>greetingForm</managed-bean-name>
<managed-bean-class>com.mycompany.GreetingForm</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>id</property-name>
<value>#{param.id}</value>
</managed-property>
Any pointers/suggestions at the earliest on how to pass the value of Id on a click of update button from greetingForm.faces to greetingForm.java will be highly appreciated
I am willing to upload my war file

Is it possible to call a custom method in App Module from a backing bean?

I would like to know if a custom method in App Module can be called from inside a backing bean.
I am not sure if it is logically right to call, from a backing bean, a custom method in App Module. But would like to know if that makes sense or if it is possible.

Hi..
Yes it is possible.You have to add that method for client interface of AppModule.Now you can see that method in Data Controls(Refresh the data control). To call this method using bean it should add as method action to bindings(Click Bindings>+>methodAction>and Create action binding).
Now you can call this method in bean class.
Check following example use this concept to execute view criteria

How to set values in a CoreTable programmatically from a backing bean

Hi,
One of the columns in my CoreTable is "af:inputText" field, I need to set the value of inputText field in each row from a backing bean.
I have bound this table to a component in the bakcing bean and in the setMyCoreTable method I'm also preselecting certain rows. For all the preselected rows I need to set a value in the inputText field.
Can someone point me to some code samples or give me some ideas to solve this.
Thanks

Thanks dvohra,
I looked at the post you suggested yesterday, but I wasnt sure how I can implement that in my case.
Since Im programatically preselecting certain rows in the setMyCoreTable method(which is the accessor method), I was hoping I could prepopulate the input text field as well in the same method.
For your reference below is the code from jspx and the backing bean.
<af:table value="#{bindings.ProgramComponentList.collectionModel}"
var="row"
rows="#{bindings.ProgramComponentList.rangeSize}"
first="#{bindings.ProgramComponentList.rangeStart}"
emptyText="#{bindings.ProgramComponentList.viewable ? 'No rows yet.' : 'Access Denied.'}"
selectionState="#{bindings.ProgramComponentList.collectionModel.selectedRow}"
selectionListener="#{bindings.ProgramComponentList.collectionModel.makeCurrent}"
binding="#{backing_EditProgramBean.compsTableComponent}">
<af:column sortProperty="Name" sortable="true"
headerText="#{bindings.ProgramComponentList.labels.Name}">
<af:outputText value="#{row.Name}"/>
</af:column>
<af:column sortProperty="Description" sortable="true"
headerText="#{bindings.ProgramComponentList.labels.Description}">
<af:inputText value="#{row.Description}" simple="true"
required="true"
columns="30"/>
</af:column>
<f:facet name="selection">
<af:tableSelectMany id="tableSelectMany1"/>
</f:facet>
</af:table>
CODE FROM BACKING BEAN ---------
public void setCompsTableComponent(CoreTable compsTableComp) {
ManageProgramsServiceImpl serviceImpl =

ViewObject searchProgramView = serviceImpl.findViewObject("SearchProgramView");
Row currProgram = searchProgramView.getCurrentRow();
ViewObject view = serviceImpl.findViewObject("ProgramComponents");
view.setWhereClause("ProgramsComponents.PROGRAM_ID = " + currProgram.getAttribute("ProgramId"));
view.executeQuery();
view.setRangeSize(view.getRowCount());
view.executeQuery();
Row[] programComponents = view.getAllRowsInRange();
RowKeySet rks = new RowKeySet();
ViewObject compTypesView = serviceImpl.findViewObject("ProgramComponentList");
compTypesView.setRangeSize(compTypesView.getRowCount());
compTypesView.executeQuery();
Row[] compTypes = compTypesView.getAllRowsInRange();
for (int i = 0; i < compTypes.length; i++) {
String code = compTypes.getAttribute("Code").toString();
for(int j=0; j<programComponents.length; j++){
String programCode = programComponents[j].getAttribute("ComponentType").toString();
if(programCode.equalsIgnoreCase(code)){
rks.getKeySet().add(compTypes[i].getKey());
compsTableComp.setSelectionState(rks);
List li = compsTableComp.getChildren();
System.out.println("****** li : " + li.size());
//System.out.println("****** row count : " + compsTableComp.getRowCount());
//System.out.println("****** count : " + compsTableComp.getRows());
this.compsTableComponent = compsTableComp;
The table children size(li.size()) comes up as zero and [compsTableComp.getRowCount()] gives an exception. Can you please provide any help. Seems like Im off track with this whole thing.
Thanks

Call a Function From a Backing Bean

Hello,
I am trying to call a PL/SQL function from a Backing Bean but i am getting a getDBTransaction error. Here is the example i was trying to do in a backing bean.
I Am getting the employee ID , sending it to a function that calculates the annual salary and then through a button whose code is in the backing bean, showing a message on the screen with the annual salary.
I am getting the JBO-25301 error.
Can't i use getDBTransaction in my backing bean.

Please have a look at the following thread:

JSF backing bean accessibility from external class

I am using JSF in my application. Consider i am assigning a value of the inputtext field to a string in my managed bean. This bean has the getters and setters for the string.
Now my requirement is to get the value of the string i.e. the string value entered in the input text field in another class file. If "A" is a backing bean, I want a class B to access the values(in this case the inputtext value) from A.
Thanks in Advance.

Below is the code where i am using the inputtext tag in the JSP page
<h:inputText value="#{person.name}" />
"person" is the backing bean which is declared in the faces-config.xml
PersonBean code:*
package jsfExample;
public class PersonBean {
     private String name;
public void setName(String name) {
          this.name = name;
public String getName() {
          return this.name;
Now i have another class in the same package as shown below.
package jsfExample;
public class worker extends PersonBean{
//this function should use the variable name present in the backing bean//
     public void access(){
     PersonBean person= new PersonBean();
     String str=person.getName();
     System.out.println(str);
//I am getting null value in the str variable inside here//
but if i print the variable inside the backing bean(*PersonBean*) it is working fine.
