Help:accessing beans method

hello
i have made one application in which i have made two beans under different packages. i am trying to access beans through jsp pages. i am able to access beans and their methods but when i add new method in bean and tried to access that method with different new jsp page say page1.jsp. I am not able to access new method though i am able to access old methods of same beans with this new jsp page. then i made new bean and copied that method in this new bean . then i tried to access that method of this new bean with page1.jsp and i am able to access it can any body guide me what is the reason for this. i want to run this method in old beran rather than new bean
my directory structure is:
projectlms---main folder
addstream---old jsp page
page1---new jsp page
web-inf/classes
com-------main packageof beans
ProgramManager----sub package of classes
bean1--------old bean
new bean------new bean just for testing
now the problem is that i want to add one more method to bean1 and want to access it through pag1.jsp
but i am not able to access it and same method when i take to new bean i am able to access that method through page1.jsp
but i am able to access old methods of bean1 through page1.jsp
thanks
regards
vivek

Could be a caching issue.
Wipe out the COMPILED jsps and try again.

Unable to call bean method at second JSP.

I have a Bean called "Database" in that two methods
1.public String methodReturnsString()
2.public List methodReturnsList()
And also i have three jsp's.
1.First.jsp
2.Success.jsp
3.fail.jsp
i called methodReturnsString of "Database" in the First.jsp ,after receiving intended String from the method methodReturnsString() i.e "success" or "fail" i can goto Success.jsp. or fail.jsp.
Assume i got String "success" eventually leads me to Success.jsp , In this Success.jsp i was trying to access Bean method methodReturnsList() , Now the problem is I cant access the Bean method methodReturnsList() in Success.jsp, where i want to print the List that is returned by methodReturnsList().
Can anybody tell me what is the mistake i am doing.
here is "Success.jsp"

Help accessing methods in classes load with forName()

Hi all,
I am dynamically loading classes at runtime by using Class.forName() and .newInstance(). Is there any way I can access the methods of those classes after they are dynamically loaded? It doesnt seem that they are available for use.
Any help would be appreciated.
Ryan

To clarify, are you asking how to invoke a method on an Object without knowing its class? In any case you should use the reflection api that are avaliable.
Ex: cl = Class.forName(); Method[] methods = cl.getMethods(); for(int i = methods.length; i-- > 0;) System.out.println(methods[i-1].getName());
or
methods[i-1].invoke(cl.newInstance(), new Object[]{});

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 to set button disabled property based on backing bean method

JDeveloper 12c
I have a table and a button on the page. When user selects certain table row I want to enable/disable the button.
My backing bean (which has backing bean scope in the task flow where the page is) is
package view.backing;
public class Studybrowse {
 public Studybrowse() {
 public String b1_action() {
 //Do something here
 return null;
 public boolean b1_user_auth(){
 // Do something here to return true or false
 return true;
My button is something like this:
<af:button text="Do something" id="b4" action="#{backingBeanScope.Studybrowse.b1_action}"
 disabled="#{backingBeanScope.Studybrowse.b1_user_auth THIS DOES NOT WORK}"
 partialTriggers="t1"/>
The first problem is in design time, it says: "Reference backingBeanScope.Studybrowse.b1_user_auth not found"
and in runtime, desired behavior does not work.
Any help is appreciated

Timo:
I changed my backing bean method like this:
 public Boolean isUserAuthorized(){
 // some code here that will return true or false, hardcode to true for now
 return true;
and the button disabled property like this:
 <af:button text="Go to Reports!" id="b5" action="#{backingBeanScope.Studybrowse.b1_action}"
 disabled="#{backingBeanScope.Studybrowse.isUserAuthorized}"
 partialTriggers="t1"/>
Still same problem in design time there is a warning and 500 error in runtime.

Error while accessing EJB method from JSP

Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component. I.e., I would like to take an action when a user clicks in a column in a datatable.
Cheers,
Ralph

How to call a bean method through javascript?

public String doAction() {
 tryStuff1();
return "samplejsf";
public void tryStuff1()
System.out.println("Enter the trystuff method");
 FacesContext facesContext = FacesContext.getCurrentInstance();
UIViewRoot uIViewRoot = facesContext.getViewRoot();
Application application = facesContext.getApplication();
UIComponent formComp=uIViewRoot.findComponent("subbody:form1");
HtmlPanelGrid grid= new HtmlPanelGrid();
grid.setId("panelgrid2");
grid.setColumns(2);
grid.setBorder(2);
//UIComponent panelGridComp=formComp.findComponent("subbody:panelgrid1");
//UIComponent panelGroupComp=panelGridComp.findComponent("panelgroup2");
 HtmlOutputText output = new HtmlOutputText();
output.setValue("dynamic jsf text2");
System.out.println("hello output text2");
output.setRendered(true);
grid.getChildren().add(output);
HtmlInputText input = new HtmlInputText();
input.setSize(40);
input.setValueBinding("value", (ValueBinding) application.createValueBinding("#{sample.text2}"));
input.setRendered(true);
grid.getChildren().add(input);
System.out.println("hello output text1");
grid.setRendered(true);
formComp.getChildren().add(grid);
System.out.println("hello output text3:");
formComp.getRendersChildren();
formComp.setRendered(true);
public boolean getRendersChildren() {
 return true;
jsp code is
<h:form id="form1">
<h:panelGrid columns="2" binding="#{sample.formElements}">
</h:panelGrid>
<h:panelGrid id="panelgrid1" columns="1">
<h:panelGroup id="panelgroup1">
<h:outputText value="hardcoded jsf text1"/>
<h:inputText value="#{sample.text1}"/>
</h:panelGroup>
</h:panelGrid>
<h:commandButton id="add" action="#{sample.doAction}" value="add" type="SUBMIT"/>
</h:form>
when i click on the button its going into the method and diaplying s.o.p but the text box is not updated to the page.
why is it so.
i thought there may be a problem in calling the method directly thru button. i want to try thru javascript calling the bean method.
why is the page not updated.
can u help me out
thanks in advance

How to call a bean method in the faces-config file?

Hi,
I would like in my menu to call the method of a bean (it initialize some properties before opening the page) instead of opening directly the page, by I can't find how to do that.
I tried :
<managed-property>
<property-name>viewId</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
And :
<managed-property>
<property-name>outcome</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
With no success...
Can someone help me?
Thank you and merry christmas !

Hi,
a managed property only gives you a anlde to a bean or property, it doesn't execute it. To execute a bean, you can use a custom JSF PhaseListener that calls a bean method. The reference to the bean is achieve through value binding
ValueBinding vb = FacesContect.getCurrentInstance().getApplication().createValueBinding("Name of Managed Bean);
TypeOfBean theBean =(TypeOfBean) vb.getValue(FacesContext.getCurrentInstance());
.... theBean.theMethod() ...

Calling a backing bean method after load of fragment in adf

I needed to call a backing bean method after page load of fragment in adf.
I used the method suggested in:
https://community.oracle.com/message/11044570
only difference is im giving the if clause as:
if (refreshFlag == RegionBinding.RENDER_MODEL ) {
instead of
if (refreshFlag == RegionBinding.PREPARE_MODEL)
It was working fine, but page was not getting refreshed so used the code as mentioned in example:
public void refresh() {
 FacesContext facesContext = FacesContext.getCurrentInstance();
 String refreshpage = facesContext.getViewRoot().getViewId();
 ViewHandler viewHandler =facesContext.getApplication().getViewHandler();
 UIViewRoot viewroot = viewHandler.createView( facesContext, refreshpage);
 viewroot.setViewId(refreshpage);
 facesContext.setViewRoot(viewroot);
Now issue is once page is loaded and backing bean method is called, the refresh code refreshes the page and upon page load, refresh method is called again in recursive fashion.
please advise what to do in such scenario?
I tried to do selective refresh using some variable(also with static) but it does not help as page wont be refresh at all or page will keep refreshing recursively.

Use clientListener on the page load event
<af:document id=”d1″>
 <af:serverListener type=”onloadEvent”
 method=”#{<managedbean name>.<method name>}”/>
 <af:clientListener method=”onLoadClient” type=”load”/>
 <af:resource type=”javascript”>
 function onLoadClient(event) {
 AdfCustomEvent.queue(event.getSource(),”onloadEvent”,{},false);
 return true;
 </af:resource>

Problem Calling Remote Session Bean Method

Need help. I am trying to call a method in a remote stateless session bean in an EJB in my web application from a stateless session bean in a different EJB in the web application. I am getting a run-time error that says,
"java.lang.NoClassDefFoundError: dtpitb.common.sb.reports.CommonReportsHome"
ref = ctx.lookup( jndiName );
// Cast to Local Home Interface using RMI-IIOP
commonReportsHome = (CommonReportsHome)
PortableRemoteObject.narrow(ref, CommonReportsHome.class);
If while in a session bean of an EJB, I want to call a public method in the session bean of a totally different EJB, is there something in particular I am missing. I can make the call from the web application code. I can make a remote call from this session bean to itself in the exact same fashion. I just can't call a session bean in another EJB. All thoughts are welcome.
Thanks,
Pete

Thanks for replying. That could very well be the case I suppose. I'm using JBuilder and WebLogic, and JBuilder pretty much does all of the deployment descriptor code for me. However, maybe this is something I need to incorporate manually.
One EJB is in the same project as the web application code. The other EJB (common_ejb) is in another project. The calling session bean is in the project with the web app, and the remote session bean method that I'm targeting is in the common EJB session bean. Both EJBs are included in the web app's WEB-INF\lib dir and in the war file.
So theoretically, this isn't an unconventional practice I assume?
Thanks,
Pete

How to achieve Entity Bean methods ONLY by calling them from a Session Bean

Hi,
I used a session bean as a business facade to a entity bean.
In the session bean I achieve the entity bean with a jndiContext.lookup("java:comp/env/ejbEntityBean").
Now I am looking for a solution that it is only possible to call the entity bean methods or the whole entity bean from the corresponding session bean.
In other words: "How can I forbid the access to the entity bean, if the calling object is not the corresponding session bean?"
--->
I only found a way the regulate the access to the entity bean methods by declaring a security-role.
But the existence of the security-role at runtime depends on the calling user-authorizations!
Is there a way to set the entity-security-role within the session bean context?
Best Regards
Steffen

Hi Srikanth Reddy.T,
sorry, I am not looking for a special tag <entity-security-role>.
I am looking for a way to specifiy that my session bean "has" the special security-role (in my case "WebZaehlerEjbRole") of my entity bean "in my case "WebZaehlerEjbRole") that is necessary to call the methods (findAlleEntries, findByWindowId,...) of my entity-bean.
Here is the relevant part of my ejb-jar.ml:
 <assembly-descriptor>
 <security-role>
 <role-name>WebZaehlerEjbRole</role-name>
 </security-role>
 <method-permission>
 <description>method-permission</description>
 <role-name>WebZaehlerEjbRole</role-name>
 <method>
 <ejb-name>WebZaehlerBean</ejb-name>
 <method-name>findAllEntries</method-name>
 <method-params/>
 </method>
 <method>
 <ejb-name>WebZaehlerBean</ejb-name>
 <method-name>findByWindowId</method-name>
 <method-params>
 <method-param>java.lang.Long</method-param>
 </method-params>
 </method>

How to access a method of a class which just known class name as String

Hi,
Now I have several class and I want to access the method of these class. But what I have is a String which contain the complete name of the class.
For example, I have two class name class1and class2, there are method getValue in each class. Now I have a String containing one class name of these two class. I want to access the method and get the return value.
How could I do?
With Class.forName().newInstance I can get a Object. but it doesn't help to access and execute the method I want .
Could anybody help me?
Thanks

Or, if Class1 and Class2 have a common parent class or interface (and they should if you're handling them the same way in the same codepath)...Class c = Class.forName("ClassName");
Object o = c.newInstance(); // assumes there's a public no-arg constructor
ParentClassOrInterface pcoi = (ParentClassOrInterface)o;
Something result = pcoi.someMethod(); Or, if you're on 5.0, I think generics let you do it this way: Class<ParentClassOrInterface> c = Class.forName("ClassName");
// or maybe
Class<C extends ParentClassOrInterface> c = Class.forName("ClassName");
ParentClassOrInterface pcoi = c.newInstance();
Something result = pcoi.someMethod();
