ADF-Faces table and mass data

Hello Oracle,
we consider to use ADF-Faces with Spring and TopLink or Hibernate that supports all important commercial databases.
We need a solution for selecting mass data and show them using a ADF-Faces component.
ADF-Faces table looks great and is fine for for some hundred datasets. But we have customers who could do a select over 80.000 or more datasets and it cannot be the solution to load them completly in collection-model in memory.
Do you have a solution or do you plan somthing? A JSF data table component for mass data (e.g. load from database on every "next or "previous" click)?
Regards
Florian

I'm pretty new to ADF Faces etc. but I know the ADF Table component supports paging. If you're using ADF Business Components as the persistence framework it supports paging out of the box giving you exactly what you're looking for.
If you're using EJBs or Toplink I think you have to write your own paging interface but I don't know this for sure.

ADF Faces table and link to detail

Hi all,
I am trying to create a link to a detail page from an ADF table. My problem is, that the action is invoked as often as there are entries in my table. Interesting enough the param "objektId" each time contains the same primary key from the link that has been chosen. This is the code that I am using:
<h:form>
<af:table value="#{organisationListe.trefferzeilen}" var="row">
<af:column sortable="false" formatType="text">
<h:commandLink action="#{organisationListe.showDetail}">
<f:param name="objektId" value="#{row.trefferobjektId}"/>
<af:outputText value="#{row.anzeige01}"/>
</h:commandLink>
</af:column>
</af:table>
</h:form>
Does anyone know the reason for this behavior?
FYI: I don't want to use TableSelectOne as I do not want to have a radio button next to the rows - the customer insists on having a link.
Regards
Peter

Hi,
1. you don't need <af:outputText value="#{row.anzeige01}"/> if using af:commandLink because it has a text attribute. Less code is less work.
2. You cannot use the parameter for this because the request map always shows empty, try
          <af:column sortable="false" headerText="Details">
            <af:commandLink text="Detail for #{row.EmployeeId}"
                            action="#{ShowDetailLinkInTableBean.showDetail}"
                            partialSubmit="true">
              <af:setActionListener from="#{row.EmployeeId}"
                                    to="#{sessionScope.empId}"/>
            </af:commandLink>
          </af:column>in the mangaged bean
    public String showDetail() {
        FacesContext fctx = FacesContext.getCurrentInstance();
        System.out.println("---"+fctx.getExternalContext().getSessionMap().get("empId"));
        return null;
    }Note that even when using f:param the code never executes more than one time

How to select rows in adf faces table

Hi guys
im new to adf faces .I created a adf faces table with some data.My task is to select one row and if i click tht row, the data of tht row will be displayed in an input text fileds.How can i select a row in a adf faces table and give actions to rows...i read so many tutorials...none of them didnt give a correct idea....plz help me...
thanks in advance..

You're here in the Sun JSF forum, not in the Oracle JSF forum.
Try here: JDeveloper and ADF
If the ADF datatable is technically comparable with the RI datatable, check http://balusc.xs4all.nl/srv/dev-jep-dat.html to get some insights how to retrieve the selected row object.

URGENT: ADF Faces table updating issue.

I have a project that uses JSF, ADF Faces, EJB 3.0, and the ADF binding framework.
In this project, I have a page with a databound ADF Faces Table. The table has a number of read-only columns and two read-write columns. I also have an Edit button that allows the user to pop up a dialog box to edit the selected row of the table. When the user clicks OK in the dialog box, the data is passed back to the main page and the table is updated.
Everything works correctly for the read-only columns. For the read-write columns, however, the table data does not get updated following an edit. This is what I have found:
1. The table row data gets passed in to the Edit dialog correctly.
2. The data gets passed back correctly.
3. The model gets updated correctly (up to and including the database).
4. Looking at the iterator in the debugger shows the correct, updated data.
5. When the table row is getting redrawn, the getter calls for the read-write columns return the updated data.
6. As mentioned above, the read-only columns get updated correctly.
7. Updating the read-write columns directly from the table works correctly.
So, the problem appears to be in the GUI layer. I suspect that, somehow, the submitted values of the read-write columns are not getting set properly, but I cannot figure out how to do this.
Note that clicking on the Edit button results in a partial submit. In the return listener, I add a call to AdfFacesContext.getCurrentInstance().addPartialTarget(getRecipientTable()) in order to redraw the table (getRecipientTable() is the bound value of the ADF table).
Please help! We are so close to production and we need to fix this.
Thanks,
Ara

Hi,
I don't have a testcase for this, so I just come up with ideas to try
1. refresh the parent container of the table. It seems that the input text components are not triggered to refresh if the refresh is on the table.
2. If using ADF, make sure the update is performed directly on theiterator (which automatically is the case if you use a ADF bound form for this)
3. Check if executing the table iterator and then setting back the current row makes a difference

An extra column of a query in an ADF Faces Table?

Hi to all OTN Community...
I use ADF Faces, Toplink and EJB 3.0 in JDevelooper 10.1.3.1.0, and i have a question...
I need to show in an adf faces table, the result of a query like this
SELECT COLUMN1, COLUMN2, COUNT(*)
FROM TABLEX
GROUP BY COLUMN1, COLUMN2
I do this query in the TableX named queryes...and then i have acces to this named query in the dataControl, but, when i drag and drop the dataControl to a jsf page, this only shows the columns of the tableX. Then, i want to know, ¿How can i show the count(*) column in the page in a dataControl?
PD: i want to show in the adf faces table the same result if i execute that query in an sql client.
Thanx in advance...
Darklorddany

Darklorddany,
The solution to this is to add an additional method on your EJB 3.0 session-bean that exposes an dynamic TopLink report (projection) query.
The TopLink code within the method would leverage your existing TopLink mappings to do the query like:
        ReportQuery rq = new ReportQuery(Employee.class, new ExpressionBuilder());
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.addCount();
        rq.addGrouping("firstName");
        rq.addGrouping("lastName");
        List<ReportQueryResult> results = (List<ReportQueryResult>)session.executeQuery(rq);The ReportQueryResult objects are very generic map/row type containers that will not work well in your ADF binding layer. With JPA you can specify and ad-hoc Java class to contain such projection results that make them a little easier to use in clients. This functionality will be available in the next release of TopLink. Until then you will need to write some code to convert to your own result class for this query.
In my case I'll create a simple POJO like:
    public class EmployeeNameCount {
        private String firstName;
        private String lastName;
        private int count;
        public EmployeeNameCount(String firstName, String lastName, int count) {
            this.firstName = firstName;
            this.lastName = lastName;
            this.count = count;
        public String getFirstName() {
            return this.firstName;
        public String getLastName() {
            return this.lastName;
        public int getCount() {
            return this.count;
    }Now I combine the previous report query code into an EJB 3.0 session bean method:
    @TransactionAttribute(TransactionAttributeType.SUPPORTS)
    public List<EmployeeNameCount> findEmployeeNamesWithCount() {
        Session session = getSessionFactory().acquireSession();
        ReportQuery rq = new ReportQuery(Employee.class, new ExpressionBuilder());
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.addCount();
        rq.addGrouping("firstName");
        rq.addGrouping("lastName");
        List<ReportQueryResult> results = (List<ReportQueryResult>)session.executeQuery(rq);
        session.release();
        List<EmployeeNameCount> empNameCounts = new ArrayList<EmployeeNameCount>(results.size());
        for (ReportQueryResult rqr: results) {
            String fname = (String)rqr.getByIndex(0);
            String lname = (String)rqr.getByIndex(1);
            int count = ((Number) rqr.getByIndex(2)).intValue();
            empNameCounts.add(new EmployeeNameCount(fname, lname, count));
        return empNameCounts;
    }You will also need to make sure the method exists on your EJB 3.0 session bean's interface as well. Then regenerate the data control for your session bean and you should have access to drag and drop this query with its results into your JSF pages.
As mentioned this use case will be much simpler and declarative in the next release.

ADF Faces Table with a Total row calculated?

Hi there OTN Community:
I have another doubt.
I have an EJB dataControl, and i use one of his collections to display the data in an ADF Faces Table. One of the columns of the Adf Faces Table is numeric, And i have to display the Total of that Column.
I only shows 10 rows per screen, but i need to show the total of all the rows.
How i can calculate it?

Mmmmm..... You're right!...I will try that.
Thanx :)
Hey, and....You know? i was thinking, maybe i can get the iterator and then capture each object of the iterator to compute the total. That is a crazy idea?, its possible?, its not recommended? or its ok too? :P
Thanx in advance.

ADF Faces table selection from commandLink?

I'm using the ADF faces table component and would like to allow my users to make a selection out of the table from a click onto a commandLink rather than using the tableSelection facets. How can I determine the row they have clicked on?
Thanks for any help,

Hello
Sorry to restart this thread again, but if i do table.getRowData() i don't get any rows, the rowcount remains 0, but my table contains many data rows.
Is there anybody who knows what the reason can be?

ADF faces tables - range navigation table footer

Hi,
I have a strage situation using ADF Faces' table, sometimes it displays range navigation on top and bottom of the table and sometimes only on top of the table. Is it possible to show always the range navigation on top and bottom of the table? How? If not, can someone give me an example of using an selectRangeChoiceBar to implement navigation on bottom of the table?
Thanks in advance.

ADF Faces table with checkboxes

Hi,
My dev env: jdev 11.1.1.2.0
I like to implement something like yahoo mail, with a checkbox at the column header. If selected,
all rows will be selected. I assume Yahoo's email is using javascript. How do I achieve the same
thing here with adf faces table? Is there any tutorial I could reference.
Thanks in advance!

SQL LOADER , EXTERNAL TABLE and ODBS DATA SOURCE

hello
Can any body help loading data from dbase file .dbt to an oracle 10g table.
I tried last day with SQL LOADER, EXTERNAL table , and ODBC data source.
Why all of these utilities still failing to solve my problem ?
Is there an efficient way to reach this goal ?
Thanks in advance

export the dbase data file to text file,
then you have choice of using either sql loader or external table option to use.

Spry Tables and Xml Data Sets viewed in IE7

Has anyone ever run into a problem with Spry Tables and Xml
Data Sets viewed in IE7? Work fine in IE6 and Firefox, but get the
error "exception caught while loading feed.xml: [object Error]" in
IE 7. Any ideas?
Attached is the xml I'm using.
Thanks

I came looking for the answer to this question. I could not
find an answer. Eventually I found it the answer that worked for
me, a graphic designer with not much experience in xml.
The following url provided an errata file in PDF format:
www.peachpit.com/dwcs3cib
which includes the following addendum to the incomplete
instructions in the book i was using to learn about spry:
"If Internet Explorer 7 is your primary browser, you'll nee
to take some extra steps to view spry dynamic content locally.
First, your site must be within the local server webroot; be sure
your Lessons folder is stored within the Inetpub>wwwroot folder.
Next, double-click the site name in the files panel to open the
Site Definition dialogue. Click the Testing Server category; from
the Access List choose Local/Network. Click Okay to close the Site
Definition dialogue. Now, when you preview your page with Internet
Explorer, your local Web server (localhost) serves the page as
designed."
Horray for me! Now i can move on from here and actually get
some work done!

Create a table and upload data in MS ACCESS from SAP ABAP programming?

Hi All,
How to create a table in MS ACCESS database and Upload SAP database table data into MS ACCESS table using ABAP programming?
Explain: My client requirement is " If he/she runs a ABAP Program, that will create a table and upload data into MS ACCESS Database table in background. "
Could you please give the solution or code? I know the program RIACCESS and I went through the SAP Note 583698.
Is this only solution for this? Or Any other possibilities?
Please give me solution.
Thanks in advance.

Hi,
It is not possible to create tables in a non SAP schema from inside SAP.
The SAP-Oracle license also does not allow you to create the table (see note 581312):
the following actions, among other things, are therefore forbidden at database level:
Creating database users
Creating database segments
Querying/changing/creating data in the database
Using ODBC or other SAP external access methods
Please refer following link,
[Ckick Here|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do]
You can also do it by LSMW,
If you are using Access 97, you can download directly into an access
database from SAP. See program RIACCESS for details. You have to establish
an RFC destination PS_ACCESS_1 and 2.
There are then a couple of function modules. Go to SE37 and put in
msaccess and hit PF4.
The following is from the readme file: sapgui/ps/readme.sap
For the MS-Access interface SAP delivers 4 files:
WDPSASTR.EXE This is an RFC server program that is called by SAP R/3
(PS module). This program creates a MS Access database. The structure
information of the tables is transferred from R/3. In addition to
these tables a table named DDIC is created. This table contains the
structure information and should in no case be modified or deleted.
WDPSATAB.EXE This is an RFC server program that is called by SAP R/3
after WDPSASTR. This program filles the tables of the database with data.
There must not be made any changes of the structure of
the tables between the calls of WDPSASTR and WDPSATAB.
WDPSAZET.EXE This is an RFC client program that triggers work/time
confirmations in the PS module of SAP R/3 (like transaction CN27 Collectiv
confirm).
WDPSAMAT.EXE This is an RFC client program that triggers material
confirmations in the PS module of SAP R/3 (like transaction MB1A - Goods
Please also refer following links,
[Click here|Upload data from MS Access tables, to SAP tables.;
Before using the program "RIACCESS", you need to install the PS utilities, which are part of SAPGUI install CD.
It is available in the "SAPGUIPS directory".
Then do the followings :
1. Select transaction code SALE -> Systems in network-> Define RFC Destination.
2. You will need two RFC destinations (TCP/IP connections for the front-end workstation).
Setup the two RFC destinations PS_ACCESS_1 and PS_ACCESS_2 and you'll have to get them to point to
wdpsastr.exe and wdpsatab.exe respectively.
3. Then execute RIACCESS and choose PS_ACCESS_1 to generate access tables.
The system must also be able to access the RFC-DLL files (librfc2.dll, librfc3.dll, librfc4.dll, librfc5.dll, librfc6.dll, vrfc.dll).
Please note that Access only supports tables with up to 255 fields.

Separate table and index data in RAC database

Hi Experts,
Our database is Oracle11g RAC database. I need your expertise on this
Do we need to retain the table and index data in two different tablespaces for performance perspective in RAC database too?
Please share your practical experience…Thanks in advance.

In my opinion, if there is striping implemented then performance shouldn't degrade even if the index and table blocks are in one tablespace. Exactly.. striping is NOT a good idea at tablespace level as a tablespace is a logical storage device. It is very difficult to stripe comprehensively/correctly at that level, if not impossible.
Striping is a function of the actual storage system and need to happen at physical level. A proper RAID0 implementation.
So the question about multiple tablespaces for a performance increase should not be about striping - but about issues such as data management, block sizes, transportable tablespaces and so on.
Thus my question (at the OP) - what performance problems are expected and are these relevant to the number of tablespaces?

Problem in implements ADF Faces: Detecting and handling user session expiry

Hello everybody
I´m trying to implement a method to handle user session expiry as explained by frank nimphius in his blog.
http://thepeninsulasedge.com/frank_nimphius/2007/08/22/adf-faces-detecting-and-handling-user-session-expiry/
I have implemented the class bellow and add the filters in web.xml. However when I add the JavaServer Faces Servlet to sign the filter, my hole application get nuts. I try to publish the applicatoin in the OAS and it seems that it already starts expired.
Someone konw what I´m doing wrong?
I use the filter
<filter>
<filter-name>ApplicationSessionExpiryFilter</filter-name>
<filter-class>adf.sample.ApplicationSessionExpiryFilter</filter-class>
<init-param>
<param-name>SessionTimeoutRedirect</param-name>
<param-value>SessionExpired.jspx</param-value>
</init-param>
</filter>
then I add
XML:
<filter-mapping>
<filter-name>ApplicationSessionExpiryFilter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
package adf.sample;
import java.io.IOException;

import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
this is the class
public class ApplicationSessionExpiryFilter implements Filter {
private FilterConfig _filterConfig = null;
public void init(FilterConfig filterConfig) throws ServletException {
_filterConfig = filterConfig;
public void destroy() {
_filterConfig = null;
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
String requestedSession = ((HttpServletRequest)request).getRequestedSessionId();
String currentWebSession = ((HttpServletRequest)request).getSession().getId();
boolean sessionOk = currentWebSession.equalsIgnoreCase(requestedSession);
// if the requested session is null then this is the first application
// request and "false" is acceptable
if (!sessionOk && requestedSession != null){
// the session has expired or renewed. Redirect request
((HttpServletResponse) response).sendRedirect(_filterConfig.getInitParameter("SessionTimeoutRedirect"));
else{
chain.doFilter(request, response);
I'm really having trouble controlling user sessions. if someone know where I can get materials to learn how to implements session in Jdev ADF + BC, I´m very grateful.
Thank you Marnie
