Difficulty in setting proprties in session/request bean

Hello,
I have a datatable which has 3 columns displayed and one hidden.The first cloumn is of type Hyperlink.When i click on this hyperlink i need to open a popup window so that i can edit the record values. The problem im facing is that i can open a popup window using the window.open() methode ,but this is javascript function.i need to carry the id value to a next page so that i can retrive the details.How do i set the id value or rather all the row values in the request or the session bean.
In the next page i need to populate the textfields with the existing values passed from the previous page.
The problem I'm facing is to open the window using javascript function and also set the bean properties.How can i caombile these together so as to solve the problem of passing values between two pages. As show in one of the tutorials
Please let me know at the earliest
Thanks in advance
abhi

Hi,
Thanks for the reply but sorry i havent really understod what u have mentioned .Please could you provide some more details as to how i can access the requestBean to set the values. I get the id when i call a function as
onClick="modalWin('#{currentRow.value['ID_PLAN_PERSON']}');"
hence the id is available in the javascript level.
Thanks
abhi

Need Clarification - Request Bean vs Session Bean?

Could someone clearify to me the difference between a Request bean and Session bean and when to use which one.
In a netbeans Visual Web Project I notice that the backing beans or code behind files that the web pages use are request beans but there is also a Applications Bean, Session Bean, and Another Request Bean.
What type of logic should be going where in terms of the jsp's request bean, the single session bean, and single request bean?
A few years ago when I was in school we created regular Web projects that used session beans as the backing beans which handled all the logic and passed data to and from a EJB layer which did all the Database connectivity.
And finally where do EJB fit into this style of Visual Web Projects?
Thanks,

So in terms of where certain types of logic goes I would so something like this login example:
User clicks a Login button, this is bound to the RequestBean, the request beans checks the session bean if user is logged in, if no then use a EJB to validate against DB, return true/false. Set user login state in the session bean? That a proper flow and useage of the different types of beans?
When all is said and done the request bean would be used to forward off actions fromt he jsp to wherever they need to go?

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Master-Detail Problem SESSION & REQUEST

I'd really appreciate some help with this:
I got a very simple master detail application, with a data table in the master page that gets it's data from a spring-hibernate bean, pretty straightforward.
My business requirement indicates that at first the list will be empty, and after selecting a few criteria values, the list should return with the results(query results).....
I'm using one of the columns with a commandLink tag as usual, to go to the detail page like any number of applications you have seen.
Now the problem arises in that, if my backing bean for my list and criteria is set as a SESSION, everything works fine. However if i set the backing bean in REQUEST scope navigation doesn't ocurr acording to the action and it just redisplays an empty list in the same page (the master list page).....
I changed everything back and forth between sun and apache's releases and nothing...tried a bunch of different things and nothing either...the log doesn't show any exceptions or anything...
Anybody have a clue on this?????

What is the meaning of initialFlag?
If the bean in request scope, when firstly invoking
getPersonData()
the flag is true because queryGenerator() is not
invoked yet in the request.
If the bean in session scope, the value of
initialFlag may hold to be false
since invoking queryGenerator() in the previous
request.initialFlag is just something I use to bring back an empty list
when the action is performed....
However my problem is not displaying the list correctly, is actually Jumping to the detail form (a different JSP) from the commandLink on the datatable results....,
instead it just re-renders the same page (just like if there was a conversion or validation error)

Keeping the values in Request bean across more than 2 pages

Hi...,
I have created a Bean with request scope & want to access it across 3 different pages.
From the 1st page once I submit the values , I do a forward (redirect=no) to the second page where I can print the values . From the 2nd page I then do a forward to the 3rd page (redirect=no) & I loose the values.
How do I keep the request bean active across multiple pages. But I don't want to make it session as this is a form to enter values & our users might open multiple forms as the same time.
Regards,
Praveen

Hi....Balu,
We are having a issue when using ajax on top of JSF . Setting the variable hidden is somehow not working.
Secondly, what is requestMap & where can I find the information.

Strange Session/Entity Bean Cross-Instance Calls in Cluster

In one of our enviroments, we are seeing session entity bean cross-instance
          calls that are hard to explain. The following is our configuration:
          The cluster contains 4 instances on 2 machines (2 on each machine). The same
          beans are deployed to each instance. "jndi.properties" is on the classpath
          for the each instance with jndi provider url = mach1inst1-ip, mach1inst2-ip,
          mach2inst1-ip, mach2inst2-ip:70001. Same servlets are also deployed to each
          instances.
          Requests from the web are load balanced through weblogic's proxy plugin for
          IPlanet and are forwarded to the 4 weblogic cluster instances. The servlet
          processing the requests calls a stateless session bean which uses an entity
          bean. The entity bean is configured with "home-is-clusterable" set to
          "false".
          What we have observed is that when all 4 instances are up, sometimes (even
          when the load is not high) the session bean is accessing entity bean from an
          instance on one machine to an instnace on another machine, while if only one
          machine (with 2 instances) is up, we don't see such calls.
          My theory is that because the jndi provider url is the same for all
          instances, the jndi lookup from each instance goes to the instance bound to
          the first IP specified in the provider url: machine 1 istance 1. If the
          request is from machine 2, because of co-location optimization, even though
          the home stub is from machine 1 instance 1, the session bean returned from
          the home stub actually is from machine 2. However, when the session bean
          does jndi lookup to get an entity bean home, the home stub is from machine 1
          and instance 1. And unfortunately, because the entity bean home is not
          clusterable, the stub can only point back to machine 1, co-location can not
          work. Thus entity bean from machine 1 is referenced by the session bean
          located on machine 2. I do not have a chance to verify this. But it seems to
          make sense to me.
          Unfortunately, I don't feel that I have a theory to explain why we don't see
          cross instance session entity bean calls when only 1 machine is up (with 2
          instances).
          Any ideas or hints would be greatly appreciated.
          Thanks,
          David Chen


rs = stmt.executeQuery() , insert statement is not a query. So use executeUpdate.

NullPointerException When trying to Get Session Scoped Bean data in another ManagedBean

hello
i wont to access to some data in my session scoped bean from a request bean so when i try to get this data all i get is
com.sun.faces.mgbean.ManagedBeanCreationException: An error occurred performing resource injection
on managed bean «discussionlaoder»
in the end of the exception there is
Caused by: java.lang.NullPointerException at Hiber.discussionlaoder.init(discussionlaoder.java:35)
this is my code:
1-the request scoped bean
@ManagedBean
@RequestScoped
public class discussionlaoder {
private MyadmninHelper halper;
@ManagedProperty(value="#{serviceBean}")
     private ServicesBean serviceBean;
    @PostConstruct
    public void init() {
      halper=getServiceBean().getHalper(); // line 35
//seter and geter code
2-the sesions scoped bean
@ManagedBean (eager=true)
@SessionScoped
public class ServicesBean {
    private MyadmninHelper halper;
//seter and geter code
am using glassfish server 3.1
thank's for help

What you need to do is fix all those typos in your code, then you don't have to override names.
- the proper Java class name is DiscussionLoader, not discussionlaoder (fix english typo also)
- if you want to inject a class named ServicesBean, then also call the property the same.
@ManagedProperty
public ServicesBean servicesBean;
But what you're doing now is call the class 'ServicesBean' and then in your managed bean declaration you seem to change your mind and it should all of a sudden be 'serviceBean'. Well then rename the class so you don't have your typo anymore!

Creating a dynamicly sorted datatable from myfaces using request bean.

Hello.
Using MyFaces...
Has anyone got this working, all i get is a "Base is null" exeption when following the example sortTable.jsp from the myfaces source.
I use a BeanManager.prepareBeans(request) whom i call att the first line of the jsf file. The prepareBeans creates the beans and sets them using valuebindning, all beans are reqeust beans and should be so.
The created beans are displayed at the page with the sorting headercells rendered. When i hit the sorting header a exception occures, this can be fixed by using session beans but i dont want that.

Well i did not get this working and i am now creating my own custom component.

Session in bean

I have a bean. At the end all variables are set to "". But anyway I need to insert it into a session before, but it seams that I can�t use sessions in bean.
// Clear the form
user = "";
password = "";
rpassword = "";
session.setAttribute("icq", iicq);
iicq = "";Andreas

Or how would you add session attributes to the bean, if thats possible I do not need to use a servlet.

Performance of Session Stateless Bean in WebSphere with connection to DB

Im using WebSphere Advanced Single Server Edition Version 4.0.1. and a WebSphere DataSource to get my connections to Microsoft SQL 2000 (using netdirect's JSQLDriver).
For the EJB I set the transaction to 'requieresNew'.
For testing purposes I had been testing some code I'll be using in a Session Stateless Bean inside a servlet's method. In my servlet I use one single connection and preparedStatements to improve performance.
When I test it on the Servlet, this process takes around 3 minutes to complete, but when I put this code inside a Session Stateless Bean and call it from this servlet's method, it takes around 30 minutes to complete!. How is this possible?!
Worst of all, when the EJB ends and the process returns to the Servlet, it throws me this exception.
com.ibm.websphere.ce.cm.StaleConnectionException: class com.ibm.ejs.cm.proxy.PreparedStatementProxy is closed.
The code uses some utilities from a Framework we created, but I really doubt it affects the performance since I put such classes in a jar file and the EJB is accessing such classes correctly.
I thought that maybe I was missing something related with how I get the connection inside the EJB, but I had no luck trying to figure this out.
This is the code in my EJB, commented code was in use when this code was tested in the method of the servlet (some code has been removed or modified, so I just left the 'main' body of the code):

I forgot to mention that I create a connection (autocommit false) at the begining of my servlet, which I use throught all the servlet, then I call the EJB, and after the EJB succeds I also close the transaction in the Servlet (to commit what is on the servlet, not the EJB). Thats why I set the transaction in the EJB to requiresNew, so after the EJB ends it commits its own transaction, Am I right?.
The Exception I get I think its because the connection used in the servlet timed out while waiting for the EJB to finish.
This issue has become urgent, so please if you know why I have this problem reply ASAP.
Thanks!

Using Query String Parameters with Session Scoped bean

I would like to pass query string parameters from a product page (user clicks on a specific product commandLink) that is request scope to a details page that is session scoped.
The problem is that the session scoped page only handles the first request. If you view the details of a product and then navigate back to the product page and choose another product ... the details page will not handle the new query string parameters and display the details for the first product chosen.
Is there a way to make the session scoped bean recognize the query string parameters past the first request?

I was able to replicate this problem with a very simple app that performs a redirection... just like the real app. Here's the simple app that I put together:
From request scope page:
<f:view>
         <h:form>
           <h:commandButton value="Link 1" action="#{reqbean.Link1}"/>
           <br/><br/>
          <h:commandButton value="Link 2" action="#{reqbean.Link2}"/>
        </h:form>
       </f:view>
From request scope bean:
public String Link1() throws IOException
    // Add event code here...
    //redirect the user
    FacesContext.getCurrentInstance().getExternalContext().redirect("untitled2.jspx?p=1");
    return null;
public String Link2() throws IOException
    // Add event code here...
    //redirect the user
    FacesContext.getCurrentInstance().getExternalContext().redirect("untitled2.jspx?p=2");
    return null;
}At this point... I put a println in the constructor of the session scoped bean because this is where I want to get the query string params. The constructor only gets called the first time a redirect is performed.

ADF BC how to access session backing bean value in servlet

Hi everyone,
How do I access session backing bean value in a servlet?

Frank, thanks for your reply.
I'm not sure how I can incorporate this example into my situation. Let me explain more detail about my problem.
"servlet" in my post here actually means a custom servlet I wrote for rendering an image that is stored in db as ordimage. In this servlet, I get hold of my appmodule by using Configuation.createRootApplicationModule(). By doing so (If I'm not wrong) a new database session/connection is created. What I'm going to achieve is set application context for this new session/connection in db with the data stored in a session backing bean in the view layer.
I can pass the required data to the servlet thru url parameter, but I don't want to do it this way for the reason that the data may contains sensitive information.
I hope I have explained myself well.

Add FacesMessage to FacesContext in an session scoped bean HOWTO?

I have an simple question. How can I add an FacesMessage to the FacesContext in a session scoped bean.
This code works fine for request scoped beans.
String message = "Some message";
FacesMessage curentMessage = new FacesMessage(message, message);
curentMessage.setSeverity(FacesMessage.SEVERITY_ERROR); //Mark as ERROR
context.addMessage(�userForm�, curentMessage);          When I change bean scope to "session" I am getting java.lang.IllegalStateException at the last line when adding message to context.
Thanks:

Thanks:
-- NerminHow do you get "context"? If you are storing it as an instance variable of the bean, then you
should expect to get an exception. The FacesContext is scoped only to one request. Instead
of storing it in the bean, use FacesContext.getCurrentInstance() each time you need to use it.

Create session scoped bean in servlet?

I am working on a log in porgram for a jsp page using servlet.
I need to create a bean in that servlet after user enter correct username and password, and the bean must have scope of session.
How do I do this?
How do I control the scope of variables in a servlet?
thank you

come on people! i just answered this 2 minutes ago! search the forums first! or a servlet book.
servlet...
Bean bean = new Bean();
bean.setValue("value");
request.getSession().setAttribute("bean", bean);
jsp...
<jsp:useBean id="bean" class="Bean" scope="session" />
<%= bean.getValue() %>
OR
<%
Bean bean = (Bean)session.getAttribute("bean");
%>

Pou Session in bean

Hi
In my loion page I have bean. In bean I have methods for connection to database and checking username and password. I would like when I take user id to put in session in bean.
Is it posible at all???
If it is how??

Create a variable to hold the session in your bean:
HttpSession session;
Create a method to to pass in the sesssion to the bean:
public void setSession(HttpSession session) { this.session = session; }
In the jsp:
<jsp:useBean id="myBean" scope="request" class="beans.MyBean" />
<% myBean.setSession(session); %>
Now you will be able to access the session and it's attributes in your bean.
