Retrieving All Objects From Session

I'm developing a JSP shopping cart application, i have problem with sessions. A user can add a product to their cart, this adds the product name and the product price to the cart using:
<%
session.setAttribute("pname", pname);
session.setAttribute("pprice", pprice);
%>
The problem I have is viewing the cart. The page must display all items the user has added to the cart. I need to retrieve all the objects from the users session.
session.getAttribute("pname") will only return the last object which was added to the session. Is there a method or mechansim to loop through all the objects in a users session?
Any suggestions appreciated.

session.getAttribute("pname") will only return the
last object which was added to the session. Is there a
method or mechansim to loop through all the objects in
a users session?You can't use session.setAttribute("pname",pname); repeatedly. Each time it will overwrite contents of existing attribute. Thats the reason why you are always getting last added value.
You can do one thing. Add pname to the Vector or Hashtable, like this,Vector v = (Vector) session.getAttribute("pname"); // Get the existing Vector in the session.
if(v == null) v = new Vector(); //If there is no attribute "pname" in the session, create an object of Vector.
v.add(pname) //add item to the Vector.
session.setAttribute("pname",v); //Now add this vector to the session.Hope this helps.

Re: [iPlanet-JATO] Re: Retrieving all Values from a Tiled View

Todd,
Let me try to explain you this time. I have a text field in a TiledViewBean.
When I display the page, the text field
html tag is created with the name="PageDetail.rDetail[0].tbFieldName" say
five times/rows with same name.
The html tags look like this.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
When the form is submitted, I want to get the text field values using the
method getTbFieldName().getValues() which
returns an array object[]. This is in case where my TiledViewBean is not
bound and it is working fine.
Now in case when my TiledView is bound to a model, it creates the html tags
as follows.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[1].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[2].tbFieldName" value=""
maxlength=9 size=13>
Now when I say getTbFieldName().getValues() it returns only the first
element values in the object[] and the rest of the
values are null.
May be we need to create a utility method do get these values from
requestContext.

I wanted to know how the getValues() method works the reason being,
when the tiled view is NOT bound to a model, it populates all the
fields with the same name as some thing likeI'm afraid I don't understand your point--can you please clarify? Do you
mean "value" instead of "name"?
What are you trying to do? What behavior are you expecting but notseeing?
>
Without further clarification, I can say that the setValues() methodsNEVER
populates data on multiple rows of a (dataset) model, nor does it affect
multiple fields on the same row. Perhaps what you are seeing is theeffect
of default values. Model that derive from DefaulModel have the ability to
carry forward the values set on the first row to other rows in lieu ofdata
in those other rows. This behavior is for pure convenience and can be
turned off, and it is turned off for the SQL-based models.

Hi,
I wanted to know how the getValues() method works the reason being,
when the tiled view is NOT bound to a model, it populates all the
fields with the same name as some thing like
PageDetail.rDetail[0].tbFieldValue
PageDetail.rDetail[0].tbFieldValue
in which case, the getValues() method works fine.
But in case where the tiled view is bound to a model, it populates
with different field names such as,
PageDetail.rDetail[0].tbFieldValue
PageDetail.rDetail[1].tbFieldValue
in this case, the getValues() doesn't work. Any soultion to this?
We are using Moko 1.1.1.
thanks in advance,
raju.

Does anyone know of is there a single method to get all values of a

resetTileIndex() / nextTile() approach.
ie Something that returns an Object[] or Vector just like ND returned a
CspVector. I tried using the getValues() methods but that allways returns
a
single element array containing the first element.
(I think now, that method is used for multi selecteable ListBoxes)Actually, no. We can add this in the next patch, but for now, I'd recommend
creating a simple utility method to do the iteration on an arbitrary model

Retrieving all values from hashmap in order you put them in

Hi guys,
I want to retrieve all values from a HashMap in the order I put them in.
So I can't use the values() method that gives back a collection and iterate over that.
Do you guys know a good way to do that ?

You can just do something like this:
class OrderedMap
    private final Map m_rep = new HashMap();
    private final List m_keys = new ArrayList();
    public Object get( final Object key )
        return m_rep.get( key );
    public Object put( final Object key, final Object value )
        final Object result = m_rep.put( key, value );
        if ( result != null )
            m_keys.add( key );
        return result;
    public Object remove( final Object key )
        final Object result = m_rep.remove( key );
        if ( result != null )
            m_keys.add( key );
        return result;
    public Iterator keyIterator()
        return m_rep.iterator();
}Then use it like this:
   for ( Iterator it = map.keyIterator(); it.hasNext(); )
       final Object value = map.get( it.next() );
   }This will be in the order you put them in. However, if you want to do this correctly, you should implement the Map interface and add all the methods. Another thing you can do is download the JDK 1.4 source, learn how they did and do it the same way for 1.2.

How to retrieve all fields from Entiy Bean

Is there a simpler way to retrieve all fields from the entity bean than calling each individual get method?
I need to retrieve the entire record not the contents of the entire table.
Though, I may eventually need to do that also.
I have 56 fields on this table. It does not make sense to code a get statement for every field.
If you can direct me to sample code that would be good.
Also, are there any good examples out there of how to create an entity bean or session bean using a local interface?
Thanks,
Jim

I think you are confusing an EJB with a DAO.
If you want to access the database why not just use JDBC?

How to remove an object from session with JSF 2.0 + Faceletes

hi all,
I have a facelets page which calls a backing bean of session scope. Now when ever i click on this page i want the existing bean object to be removed from the session . In my existing jsp i have a logic something like this to remove the object from session
<% if (request.getParameter("newid") != null) {
request.getSession().removeAttribute("manageuserscontroller");
%>
Now i have to refactor my jsp to use facelets and i should not be using scriplets anymore . I did try with JSTL but the <c:remove> tag is not supported by facelets.
Can someone help me how can i refactor this code to work for my facelets?
I really appreciate your help in advance
Thank you

r035198x wrote:
Redesign things so that the remove is done in a backing bean method rather than in a view page.Exactly that. I tend to cleanup session variables at the start and at the end of a page flow; generally the end is some sort of save or cancel action being invoked through a button but that is application specific.

Retrieving ALL values from a single restricted user property

How can I retrieve ALL values of a single restricted user property from within
a .jpf file?
I want to display a dropdown list within a form in a JSP which should contain
all the locations listed in the property 'locations'. I ever get just the default
value when I access the property via
ProfileWrapper pw = userprofile.getProfileForUser(user);
Object prop = pw.getProperty("ClockSetup", "Locations");

Well, the code you've got will retrieve the single value of the property
for the current user. You're getting the default value because the
current user doesn't have Locations property set, so the ProfileWrapper
returns the default value from the property set.
I assume you want to get the list of available values that you entered
into the .usr file in Workshop. If so, I've attached a
SetColorController.jpf, index.jsp, and GeneralInfo.usr (put in
META-INF/data/userprofiles) I wrote for an example that does just this.
It uses the PropertySetManagerControl to retrieve the restricted values
for a property, and the jsp uses data-binding to create a list from that
pageflow method.
For a just-jsps solution, you can also use the
<ps:getRestrictedPropertyValues/> tag. I've attached a setcolor-tags.jsp
that does the same thing.

How to obtain a session object from session id

Hi all,
let say that I have a list of session ids, and I want by scheduald task to check whether the session is alive\active.
I saw that the HttpSessionContext was deprecated. (see: http://javasolution.blogspot.com/2007/08/getting-session-object-using-session-id.html)
Is there any other way to check if the session is alive?

Do it the other way: let the session itself notify that it is not alive anymore.
Implement a HttpSessionListener which adds the session to list/set/map on create and removes the session from it on destroy, register it in the web.xml and run it.

Description:
1) We are using iplanet distributed session
2) We put a ArrayList of object into the session
3) Retrieve it from session immediately - no problem
4) display jsp on user browser
5) browser submit another request
6) retrieve it from session again, the above error show up. (other session attribute was able to retrieve so it is not session timeout)
if we can save the object into the session. The object 's class should be avaliable ?!?!
(currently using iplanet 6.5 with mp1 tested both on
solaris machine and win2000 machine)

I guess, the problem is due to the distributed session.
Make the session lite and check, if it works, then we can confirm that it is due to the guessed reason. Then please let me know.
Mean time I also try to reproduce the problem, and find out the solution.
Thanks and best of luck,

Adobe Form with XML interface cannot retrieve all data from SAP

hi all
I want to use the Adobe forms for the real estate module.
I had seen that adobe forms can have an interface with XML input and output as parameter.
In the interface type only the /DOCPARAMS an the DOCXML are INPUT parameters which are available.
No other INPUT parameter can be added to it.
When i try to retrieve the data in real estate there are some default function modules for retrieving the data from real estate.
But this function modules also are going to find out if the form which asks for this information has a IMPORT parameter
for the required data. For example, the SENDER data is retrieved, but before the default function module retrieve this data
the function module checks if the form has a INPUT parameter SENDER.
And that is not the case. And i cannot create the SENDER parameter to it, because this INTERFACE type does not allow it.
Does anybody know a solution herefore?
kind regards,
Anton Pierhagen

Hi Bhaskar
It is a long time ago, almost 2 years.
I created my own custom development for calling the Adobe form. This custom development uses the correct function module interface with the IMPORT XML.
The XML which i sent as IMPORT PARAMETER to the form is also created by own custom development. Via the default XML class of SAP
So that was my solution
Kind regards,
Anton Pierhagen

Error message- "LR has encountered problems reading this photo" after installing LR 5.6 on new computer and retrieving all contents from old HD from external HD.

Hi-
I got a new PC laptop, retrieved all old HD contents from my external HD, installed LR 5.6 (5.4 on previous PC) and when I tried to open up my old Lightroom catalog it has an error saying "Lightroom has encountered problems reading this photo. You will not be able to make adjustments to this photo". I tried to open the catalog straight from my external HD with the same error message. I've read about four billion forum threads to try to figure it out- files do not seem to be missing as most threads indicate. The other threads suggest there is a corruption with the file, but I don't THINK that is the case. Are there any other suggestions? If the file is corrupted, how do I find out for sure? Have I lost all my edits??
Thanks for your help and time!

But as you can see from the code that I get the Flat name in 1,Rent in 2 and bill in 3 which should be 2,3,5 respectively.Can you tell me why it is so?

We are facing a tight situation here. We have a scenario where we have 2 filter options.
1) Department ID
2) Project type
When department ID is selected all the department IDs should be populated in the combo box and the project type combo box should be empty.
Similarly, when project type is selected all the project types should be populated in the combo box and the department ID combo box should be empty.
Then, when more than one value is selected from department ID box and all the values from project type must be retrieved from query level (as per business logic).
How do we do this? Kindly help us with this situation.

Basically my situation slightly different.
I am trying to do a bulk insert on SQL Server table using prepared statement, during that time i am getting the exception. I am using JDBC-ODBC driver. However, if i do individual record insertion, it is working.
Any idea about this type of problem ?
Regards
Ramesh

How To Retrieve All Data From a Submitted h:dataTable ... ?

I have a table together with a button displayed in the browser. Upon click on the button, an action is invoked.
I would like to retrieve the data in the entire table in this action.
Because the displayed table is created by a managed bean class ListAction, "personnel" is the property of the bean class, and the "personnel" is a List, when I try to retrieve the data this way:
                                          ListAction listAction = new ListAction();
          DataModel personnelData = listAction.getPersonnel();
         List personnel = (List)personnelData.getWrappedData();The compiler says that a List cannot be converted to DataModel.
What should I do? I need guidance.

Thanks for the reply. I tried to follow your advice. Somehow, I ran into a runtime ClassCastException.
In my xxx.jsp I have
<h:dataTable value="#{arrival.personnel}" var="pInfo">
<h:commandButton id="Depart" value="DEPART" action="#{departure.updateDeparturePersonnel}"/>The "personnel" is the List that builds the xxx.jsp and it is also the List I try to access after the button in the xxx.jsp is clicked. Here in my configuration file:
<managed-bean>
<managed-bean-name>arrival</managed-bean-name>
<managed-bean-class>processAction.DepartureManagementBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>departure</managed-bean-name>
<managed-bean-class>processAction.DepartureManagementBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>when the updateDeparturePersonnel() method is called in the DepartureManagementBean.java, I got run-time ClassCastException. And I am unable to see the problems in my code.

                 // If this row is selected, add all data fields the corresponding message
                 if ( personnelBean.isSelectedPersonnel() )
                     departurePersonnel.add( personnelBean );
        return departurePersonnel;
    public List getDeparturePersonnel()
      return departurePersonnel;
    public void setDeparturePersonnel( List departurePersonnel )
      this.departurePersonnel = departurePersonnel;
}// End DepartureManagementBean.java
