Display mysql table data in a jsf page? (10 duke dollars up for grabs)

hi,
im having some trouble on how to display data from a mysql table in a JSF page under the JSF architecture. i need some help on the best and correct way of doing this?
if you could provide code on how this is done, would be much appreciated.
many thanks.

I'm going to assume that you have had experience with doing this in jsp. Watch for my comments by the **** asterisks *****. My skill level is best described as intermediate, so you'll probably want to heed replies from the more accomplished members of the community to improve upon this advice.

How to display a table data on Screen having a Table control

Hi ,
I am new to ABAP.I would like to display a table data (Eg: ZDemo) on a screen at run time.I have defined a Table control in screen. Now I want to populate data from ZDemo to table control.How can I do that?Please help moving forward in this regard.

Hi Gayatri,
After creating table control do the following steps.
1. In the flow logic section write the following code:
PROCESS BEFORE OUTPUT.
MODULE STATUS_0200.
LOOP AT I_LIKP WITH CONTROL LIKP_DATA CURSOR LIKP_DATA-CURRENT_LINE.
MODULE ASSIGN_DATA.
ENDLOOP.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0200.
LOOP AT I_LIKP.
ENDLOOP.
I_LIKP is the internal table which is used to display table data in the table control.
2. In Process Before Output, in the module STATUS_0200 write the following code:
DESCRIBE TABLE I_LIKP LINES FILL.
LIKP_DATA-LINES = FILL.
In Process After Input, in the module USER_COMMAND_0200 write the following code:
CASE SY-UCOMM.
   WHEN 'LIPS'.
    READ TABLE I_LIKP WITH KEY MARK = 'X'.
    SELECT VBELN
           POSNR
           WERKS
           LGORT
           FROM LIPS
           INTO TABLE I_LIPS
           WHERE VBELN = I_LIKP-VBELN.
    IF SY-SUBRC = 0.
     CALL SCREEN 200.
    ENDIF.
   WHEN 'BACK'.
    SET SCREEN 200.
ENDCASE.
In Process Before Output and in the module ASSIGN_DATA which is there inside the loop write the following code:
MOVE-CORRESPONDING I_LIKP TO LIKP.
So, Totally your flow logic code should be like this.
TABLES: LIKP, LIPS.
DATA: BEGIN OF I_LIKP OCCURS 0,
       VBELN LIKE LIKP-VBELN,
       ERNAM LIKE LIKP-ERNAM,

   IF I_LIKP[] IS INITIAL.

    SET SCREEN 200.
ENDCASE.
ENDMODULE.                 " USER_COMMAND_0200 INPUT
Save and Activate the program along with the screen in which you have included table control.
Hope this will help you.

New page in smart form when displaying internal table data in table

Hi ,
My requirement in smartform is like
I'm using the tables to display the internal table data in main window .
based on SORTF field in the internal table ,when SORTF field value changes all the related to that SORTF value should be displayind in the new page.
Please anybody tell me that , how to do this?
Thanks
Naveen

Hi Navi,
    Try this Logic.
1) Go to Smartform,
2) Declare a flag variable w_flag type c
3)Go to Main Window
   a) Go to table
   b) Create one more Table Line
   c) Create a CODE Line in that.
       write inside CODE as Below:-
             CLEAR: w_flag.
             ON CHANGE OF w_final-sortf.
               w_flag = 'X'.
              ENDON.
   d) Create one COMMAND Under CODE line created above.
       click on check Box "Go to New Page" ( Page1 or Page2 or give as reqd ).
       click on conditions tabe of COMMAND
       write: w_flag = 'X'.
Hope this will work

Getting problem in binding DropDown List with table data in visual JSF

Hi All,
I am new to visual JSF.
I am getting few problems while working over components.
I have succeeded in binding data of Person table in a drop down list .
By just drag drop ..it worked.
But while connecting to external DB this drag drop mechanism didn't work for me .
1st problem that i faced was by dragging method columns are not visible when i did right click-> bind to Data -> DataProvider window .
But i am successfully printed table Data in backend ie: by putting
for(int i=0; i<xn_white_listDataProvider.getAllRows().length;i++){
       System.out.println(" value :"+xn_white_listDataProvider.getValue("SUB_ID",xn_white_listDataProvider.getRowKey(Integer.toString(i))));
}I am not getting how to set Items in dropdown1
I tried putting
HelloSh.xn_white_listDataProvider.options['XNODE.XN_WHITE_LIST.SUB_ID, XNODE.XN_WHITE_LIST.SUB_ID'but it didn't work while for person data table
items="#{HelloSh.personDataProvider.options['PERSON.PERSONID,PERSON.NAME']}"it is working
when i am writting items="24,28" in dropdown1 box
& printing its value in static text Like
<webuijsf:staticText id="staticText3" style="position: absolute; left: 72px; top: 120px" text="#{HelloSh.dropDown1.items}"/> it is printing fine .
Plz help me in this regard.
Any clarification if needed plz let me know.
Thanks in advance.

<h:selectOneMenu id="menu1" styleClass="selectOneMenu">
<f:selectItems value="*#{selectitems.pc_DynamicPortletEdit.regList}*" />
</h:selectOneMenu>When we bind the list to the h:selectOneMenu the code in the JSP will be as given above.
My doubts here are
1) But when i tried to bind the list to a selectonemenu the code in the JSP is looking like this one
<h:selectOneMenu id="menu1" styleClass="selectOneMenu">
<f:selectItems value="*#{selectitems.pc_DynamicPortletEdit.regList.regList.toArray}*" />
</h:selectOneMenu>2) Also in the runtime instead of displaying the values in the dropdown, i am getting the object names (javax.faces.model.SelectItem@680d0ccc) in the drop down.
What am I doing wrong? Any help here would be usefull for me.
BTW,
the code in the backing bean for setting the values is like this
List dropListValue = new ArrayList();
    for (int x=0; x<result.length; x++){ //where result is array of string values
        SelectItem tempSelect = new SelectItem();
        tempSelect.setLabel(result[x]);
        tempSelect.setValue(result[x]);
        dropListValue.add(result[x]);
this.setRegList(dropListValue );The bean is in request scope only.

JDev 1013, Webservice as Data Control in JSF page returns error

Hello,
For a client we are starting a project with Java Server Faces in combination with web services. In order to do some testing we created a web service in PLSQL (with a empno input field and a record output) and deployed this web service on an OC4J container. We then created a (new) JSF project, used the PLSQL web service as a Data Source, and used this Data Source in a JSF page.
When this JSF page is started an error occurs validation -
DCA-40007: The value for parameter "empNo" cannot be null..
The webservice can however be called in the page, the output is shown but the error stays in the page.
Communication with support gave me a temporary solution
I've put in the page definition for both the methodIterator (getEmpIter) and the accessIterator (ReturnIterator) the Refresh="Deferred". Now the error doesn't show in the page at startup of the page. Data is presented correctly after pushing the button, though still in the Jdeveloper Embedded OC4J Server Log shows a list of
ERROR Value for parameter : 'empNo' cannot be null.
In a multi row Webservice (created by JDeveloper) however i still get this error.
(1) What caused this error?
(2) When is the next version of JDeveloper due?
(3) I am looking for documentation on the following subjects
(3.1) How a JSF page is rendered by the Oracle JSF implementation
(3.2) How to read and adjust the JSF page definition, for example the <executables> part
(3.3) Problem with the extra abstraction layer is that is very hard to find where an error occurs. Is a mechanism/documentation available to find in which JSF fase an error occurs and how to bypass it?
Regards Leon Smiers

(1) I think what is happening is that your page calls out to the Web service when you first run it without any parameter. This is why you get the error and also the reason that deffer works to solve this.
I think a solution would be to have your Web service handle the case of receiving an empty parameter.
(2) When it is ready :-)
(3.2) right click the jsf page and choose "go to page defenition" you can then edit it using the structure pane and the property inspector.
(3.3) you can run in debug mode, the code for ADF will be available when we go production, and with it a lot of more documentation.

Can I display the table content of a web page??

Hi guys I am new to java and here I need to count the words in each table and display the table with largest number of words . This being a part of my huge project. Below is my code where I have succeeded in displaying all the tables present in the web page.But I need to count all the words in the table and display only that table which has largest number of words including all the tags. So java experts please help me with this piece of code...................
import java.net.*;
import java.io.*;
import java.util.*;
import java.util.regex.*;
public class findtable{
public static void main(String[] args) {
    String inputLine = null;
    String wholeHtml = "";
int trcount=0;
    try{
      URL yahoo = new URL("http://books.google.com/books?q=+subject:%22+Science+Fiction+%22&as_brr=3&rview=1&source=gbs_hplp_fict");
      URLConnection yahooConnection = yahoo.openConnection();
      BufferedReader br = new BufferedReader
        (new InputStreamReader(yahooConnection.getInputStream()));
      int start = 0;
      while ((inputLine = br.readLine()) != null) {
        wholeHtml += inputLine;
        if (inputLine.contains("<table")){
                  ++start;
        if (start != 0) {
          System.out.println(inputLine);
        if (inputLine.contains("</table>")) {
          --start;
    catch (MalformedURLException me) {
       System.out.println("MalformedURLException: " + me);
    catch (IOException ioe) {
      System.out.println("IOException: " + ioe);
    }So any help would be really really appreciated....
The code should take care of nested tables also..
So guys looking forward for the generous help....

I have already parsed the HTML and checked all the closing of tags and corrected the indent using Tidy and then I have applied this code so some other suggestions please

Need a POP-UP which can display internal table data in ALV format

HI All,
I need to display INTERNAL TABLE values through a POP-UP. Only condition is that the window with the internal table data should be in ALV format and not in TEXT only format.
To clarify, I used FM 'POPUP_WITH_TABLE_DISPLAY_OK'   and 'POPUP_WITH_TABLE_DISPLAY', but both display the data in TEXT format and there is no provision to put the FIELD names there. Everthing needs to be put into internal table and it displays it in text format.
So I want a FM where I can display internal tabel data in ALV format( same format that would appear if you creata search help for a filed and output window would have all the ALV features like SORT buttons etc.
Hope there is some FM to achieve this ALV format data thing.
Thanks in advance for all your help.

Displaying the Selected Data in the Next Page Upon Selection????

Hi,
In my first page i have a list of data set in a displayTag with a
radio button as a decorator. When the user clicks the a particular
radiobutton the whole data (record) related to that radiobutton be selected and when the user clicks a button at the bottom the whole(selected data) should be transferred to the next page(jsp page). How
to do this??? The displayTag is using a formbean . How to get the data
from the selected record and populate it in the next page ???
Please do provide an answer for this Since it is quite urgent...
Thanks,
--JavaCrazyLOVER

It all depends on how you have the data displayed in the table?
If u have that information in Session (some kind of array), all you need to do is loop and then find the particular record and display it.

Trying to display an error message on my JSF page

Hi,
I'm very new to JSF and hopefully this will be easy to answer. I'm trying to display an error message when a user fails to login correctly. I have this on my login page:
<h:message for="userid" id="inputError"></h:message>
and in the login bean that handles the login, I invoke this method when the login fails, passing in the appropriate error string
     private void setError(String error) {
          FacesContext ctx = FacesContext.getCurrentInstance();
          FacesMessage fm = new FacesMessage();
          fm.setSeverity(FacesMessage.SEVERITY_ERROR);
          fm.setSummary(error);
          fm.setDetail("ERROR: " + error);
          ctx.addMessage("userid", fm);
But the error is not displaying upon a failed login and so I'm wondering if there is something more I need to do. Your help is appreciated, - Dave

To get the "real" client id use
ctx.addMessage(myComponent.getClientId(ctx), fm);and bind the userid input text to your backbean
view code:
<input binding="#{bean.myComponent}" ...backbean code:
private UIInput myComponent;
// getter/setter
public UIInput getMyComponent() { return this.myComponent; }
public void setMyComponent(UIInput myComponent) {
    this.myComponent = myComponent;
}I hope this helps...

Dear Gopi,
1) In decleration part you decleare like...!
    DATA: LT_SORT TYPE SLIS_T_SORTINFO_ALV,
               WA_SORT TYPE SLIS_SORTINFO_ALV.
2) Before using ' REUSE_ALV_GRID_DISPLAY' Function module
       WA_SORT-FIELDNAME = 'TICK_NO'.
      APPEND WA_SORT TO LT_SORT.
     CLEAR WA_SORT.
3) use FM : REUSE_ALV_GRID_DISPLAY. Like...!

Then use the findView method to get a pointer to the VO.

Exporting MySQL table data to a file in location of choice

Hi everyone,
As I'm still not all too familiar with JDBC and MySQL, I'm running into a problem and I was hoping somebody could give me a push in the right direction. What I want to do is create a Java tool which performs a query on a database, to then return the results in a file on the user's computer, not on the mySQL server itself. I know that you can easily create a file using the
SELECT * INTO OUTFILE
command, but this creates a file on the MySQL server, not on the computer of the person running the Java tool. Basically I would like the program to have a 'browse' button, with which I can specify where the file should be saved. Can anybody tell me how I could possibly accomplish this? I was guessing something with the JFileChooser would be an option, but can't seem to find exactly how to code it.
Thanks a lot for any input in advance, your help is greatly appreciated!
best regards

Thanks for your swift replies!
I'm sorry I had the context mistaken, I thought as it was handling MySQL data, it would be related to the JDBC theme. But your answer has definitely helped me along, thanks for that! I will look at that tutorial you linked through... Am I right in assuming that I can run the query, save the results in the ResultSet rs variable and then pass this to the file opened/created by JFileChooser?
Thanks again for your time!
