Caching using - Value List Handler

Hi All,
Iam new to Value List Framework.I had a doubt regarding the caching in Value List Handler.Suppose there are 1000 records in DB.I querying the DB using Value List Handler.I want to display the paging functionality in JSP.That is i want to display 50 recodrs each in the jsp.Then if have to provide the Link for another set of records.I had donr this functinality.What is the problem is if i click the hyperlink which is provided for PAgination Functionality now it is hiting the DB and fetching the recodrs and iam showing in JSP.I don't know how to do the Caching functionality using Value List Handler.so that i can avoid each time DB hit.First time i will hit the DB fetch all the records and store it in the Cache.Can anyone help me regarding this issue.

hi [email protected]
can you plz provide me some stuff for pagination using toplink. I am new to toplink and need to use pagination.

Transfer Objects in Value List Handler

Do we need really the EJB for Caching the data using Value List Handler.If EJB is not required then how can we cache the data using Value List Handler

Sorry for disturbing u again.Actually my requirments
is , In the Jsp page i have to display 1000You are referring to java server pages and not java script correct?
records(example) provided with pagination option ie
each page should display 50 records and options will
be given to user to see another 50 records by
clicking the pagination hyper link.This time it
should pick up from Cache memory not form DB.I came
to know thru documentation posted in website that
ValueList Handler provides the Caching Facility.Can i
achieve this by using ValueList Handler.You can achieve it in any number of ways.
Nothing in your description suggests that Value List Handler is going to help you in any substantial way.
Another
restrictions is not to use EJB.You have to get the data from somewhere.

Want detailed sample code(value list handler pattern) for my case

I am trying to write a Session Facade Bean with getAllUsers() method which get Collection pased from my UserBean(entity), to get all my users info.and I have a helper class called UserInfo
public class UserInfo implements java.io.Serializable
public String userid;
public String username;
public String password;
     public UserInfo()
     public void setUserInfo(String userid,String username,String password)
          this.userid=userid;
          this.username=username;
          this.password=password;
I dont' know How my ejb client(jsp maybe) to use value list handler pattern to implement getting all users shown.
I found http://java.sun.com/blueprints/corej2eepatterns/Patterns/ValueListHandler.html the sample code is to complex.
any one could help me figure out ...
what helper class do i need .or maybe interface
what is the best practice?
thanks in advanced.

Hi,
For a J2EE system with session facades, I've implemented that pattern based on the DTO pattern.
The idea is based on Sun's blueprint Pet Store implementation.
For that' I've created a DTO called "ListChunk", which holds a chunk of the complete list. In the Pet Store
application v1.3.2 it's called "Page".
So, those facade methods that would possibly return a huge list (such as getAllXXX and findXXX)
return a ListChunk. As arguments, those methods take start index and the maximum size.
If you want a value-list handler to control the iteration on your client side, you code such a class that
uses the facade method.
Here's some code:
public class ListChunk implements Serializable {
     private List list;
     private int startIndex;     // starts on '0'
     private int totalSize;
     public ListChunk(List list, int startIndex, int totalSize) {
          this.list = list;
          this.startIndex = startIndex;
          this.totalSize = totalSize;
     public List getList() {
          return list;
     public int size() {
          return list.size();
     public boolean hasNext() {
          return totalSize > (startIndex + list.size());
     public boolean hasPrevious() {
          return startIndex > 0;
     public int getTotalSize() {
          return totalSize;
}And a method in the facade could look like this:
     public ListChunk getAllCoWorkers(int startIndex, int maxSize, CoWorkerSortBy sortBy) {...}

Value-list handler, value-list iterator and session-facade strategy

Hello all,
Further to an earlier post, I rewrote my post trying to me more accurate in my question.
Here is my problem:
I am trying to implement the value-list handler design pattern using the session facade strategy. In the pattern as it is described here
(http://java.sun.com/blueprints/corej2eepatterns/Patterns/ValueListHandler.html) the client accesses the value-list handler AND the iterator directly.
As I chose the session-facade strategy having my value-list handler as a stateful session ejb, I don't know how the client is going to access the iterator. I see only one option: Having the client access the iterator through the ejb value-list handler. This requires adding new methods to the ejb.
Is this the correct way of doing it? Is there another way of doing this?
Thanks in advance,
Julien Martin.

u can use project list handler as ur session facade.
regarding ur second question ..session facade and value list handler session bean which is also a session facade( but there is difference between first and second) so u can use session facade and value listhandler

Connecting To Same Value List Handler

I have a question about using the Value List Handler pattern. Right now I am just working on the design of my application (class diagrams, scenario diagrams, etc).
I have a VLH that will retrieve data from the DB (via a DAO) and will return data to the caller. The VLH basically fronts the DAO. The caller in this case will be a Business Delegate. So the call sequence is:
client (JSP) --> Business Delegate --> Value List Handler --> DAO
Now the VLH is a stateless EJB. But the Business Delegate is just a plain Java class that will get instantiated on every call to the server. My hope is that it will connect to the same VLH instance (I use a ServiceLocator). But I'm not sure this will happen.
According to what I read about Stateless Session EJBs, they are dedicated to a single client. But what is the "client" in my scenario? Is it the browser session? Or is it the Business Delegate? If its the latter, then will new instances of the Business Delegate be able to connect to the same VLH?

Use a stateful session bean! Says so on the Sun Blueprints site for this pattern.

How can we use C# to read dynamic parameter's value list from .rpt?

I'm using Cystal Report 2008. We know starting from CR XI we can create dynamic parameters, the list of items of this kind of parameter are fetching from database. So in general the SQLs to get the list of values for dynamic parameters are stored in the .rpt.
In Crystal Report Designer, if I preview a report with dynamic parameters, it will first query the database and then show the input dialog with list of values from database for user to choose. My question is can we implement the same thing by our C# code? I'm planning to use C# code to read this dynamic parameter's value list from .rpt and render them on the web page. Then pass back the user selected values to the .rpt to run the report after user make the choice. I didn't find any APIs can do this. Is it possible?
Thanks in advance!!

Hi,
Can you explain a bit in detail, I have similar scenario. I am using the following code but not getting the Column name for dynamic parameter list.
foreach (ParameterFieldDefinition prm
                          in reportDocument.DataDefinition.ParameterFields)
                try
                    string vParameterFieldName;
                    *vParameterFieldName = prm.ParameterFieldName.ToString();*

You don't need a cfloop. Try an IN(...) clause instead.
Obviously you have to validate that the #riderlist# is not empty

How to use array list with fixed values to insert record in trigger

I have a list of number 1,30,40,45,60 . These numbers are not being changed so I don't need to keep in a table. So have to create a after insert trigger for
As
Begin
@list = 1,30,40,45,60 // Array value
for i=1 to @list.count
Insert into mappingtable(arrayvalue,itemcode) values (list[i],Inserted.Itemcode)
Next
End
Please can you help with a code
Regards
Pol
polachan

Be careful what you assume - rarely are lists of values like this truly static. One thing to keep in mind that arrays in sql server are tables. So, one example is:
set nocount on;
/* represents the virtual inserted table in your trigger */
declare @inserted table (itemcode char(4));
insert @inserted (itemcode) values ('ABCD'), ('JJKL');
select * from @inserted;
select * from @inserted cross join (values (1), (30), (40), (45), (60)) as arrayx(value);

How to fill or bind data using Value Node in Tree Node

In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data. After/before this, you would need to build table and refresh in do-prepare_output of IMPL class.In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data.

ztyped_context->resultlist->build_table( ).
IF ztyped_context->resultlist->node_tab IS INITIAL.

Also the EH_ONEXPAND has to be implemented and event handled in DO_HANDLE_EVENT. But this expand event has to be delegated to context node directly as CL_BSP_WD_CONTEXT_NODE_TREE will already have the implementation.
ztyped_context->resultlist->expand_node( lv_event->row_key ).
Where in result list is the node ZL_CLASS_CN00.

Report using Shuttle List

Greetings
I am using Apex Version 4.2
At first, I had created an item P31_JOB_CATEGORY that was a radio button. Upon selecting a value for the radio button, a report was generated. The query is as follows
select a, b, c
from Table A
where A.Job_Category = :P31_JOB_CATEGORYThis gave me the desired report. Now I want to change the radio button to a shuttle list so multiple values can be selected for the job category and generate a the report accordingly. Instead of one value, I can have 2, 3, or all. How would I alter my query to change this? would I have to use an array. I was thinking some type of "Where....In.." clause.
Thanks in advance!

Select-options - select multiple values from personal value list

Hi experts,
In my application, I am using select-options. I select the values required from the search help into the personal value list . I want to copy these values from the personal value list into my ranges table. Do I have to copy them one row at a time. Is there any way to select the values directly into the ranges table of the select-options field?

Boy, this is something we're struggling with too. So we'd like to hear others' ideas on this also.
thank you,

How create animated power view reports using sharepoint list as a data source in sharepoint 2010?

I have heard about the power view/power pivot which does this kind of animations in reports.
Can someone please guide me on creating reports which shows animations
In power view/power pivot using SharePoint List as data source in SharePoint 2010.
Thanks in advance.
MercuryMan

Hi MercuryMan,
Yes, Power View, a feature of SQL Server 2012 Reporting Services Add-in for Microsoft SharePoint Server 2010 or SharePoint 2013 Enterprise Edition, is an interactive data exploration, visualization, and presentation experience.
It provides multiple views featuring tiles, slicers, a chart filter, and a number of visualizations, including cards, small multiples, and a bubble chart. So, we can use Power View to do intuitive ad-hoc reporting for business users such as data analysts, business
decision makers, and information workers.
Currently, Power View report only supports two types of data models: PowerPivot Worksheet, and data models based on Analysis Services Tabular Model or Multidimensional Cube.
In your scenario, you can create PowerPivot worksheets using SharePoint List as data source, deploy the PowerPivot worksheet to a SharePoint Library or PowerPivot Gallery, and then generate Power View reports based on the PowerPivot worksheets on the SharePoint
site.
To use SharePoint List as data source in Excel PowerPivot, you can refer to the following resource:
