Filtering a set of collections using JSTL

Hi, i am currently facing a problem where i tried to query a set of collections in JSTL. My 1st query is using date for example,
<sql:setDataSource var="ds" driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" url="jdbc:sqlserver://192.168.250.86:1223;DatabaseName=eleavedb;SelectMethod=cursor" user="sa" password="sapassword"/>
<sql:query var="countLeave" dataSource="${ds}">
SELECT * FROM VCST_EMPLOYEE_LEAVE WHERE leave_from LIKE 'May 31 2006%'
<sql:param value="${dates}%" />
</sql:query>
After querying through date, i need to query these collection of data based on its type. But, my problem is....how to do it? This is because it's type is not unique.

Can you set pager attribute using jstl c:out tag?

I am trying to use the pager tag library from jsptags.com. The pager tag has a maxPageItems attribute. I want maxPageItems to be variable. I also want to use the jstl instead of scriptlets and expressions. Instead of writing
<pg:pager
maxPageItems="<%= myPageItems %>" >I want to write
<pg:pager
maxPageItems="<c:out value='myPageItems'/>">When I do this I get a java.lang.NumberFormatException: for input string: ""
I think this issue is documented on the jsptags website. So maybe I have no choice but to use the expression format. I guess I should also mention that I am using jstl 1.1 and jsp 1.2 (implemented in tomcat 4.1.27)
Has anyone tried this and had success?
Did I provide enough information?

Sorry, but you can't use tags as attributes to other tags (where would it end?)
You're stuck with using <%= %> syntax.

How to retain current set of records in advanced table in OAF

I have an advanced table in a OAF page. Number of records displayed is set to 5. Now, when I have more than 5 records, we can view the next set of records using navigation buttons of the advanced table. One of its column is an image which has "Action Type" as "fireAction" and "Submit" set to "True", which when clicked displays further details about the selected record in a separate region. However, in this process the page is getting refreshed and the table is again displaying the first set of 5 records even if i chose to display details about record in the next set of 5 (i.e after navigating using "Next 5" button of the table).
Is there any way to retain the current set of records displayed in the advanced table across the page refresh.?
Thanks

Solved.
Somewhere in our code, while populating one of the columns of the table, we were resetting the VO which was causing the issue. Modified that method call to add a parameter to mention from which row should the table be populated.

HT204291 Using Azul media player app on my ipad Apple tv will only display sound but not video from movies. Any ideas on a fix. I set mirroring to on but it still does not display video. It will display photos and video recorded from my iphone.

Using Azul media player app on my ipad Apple tv will only display sound but not video from movies. Any ideas on a fix. I set mirroring to on but it still does not display video. It will display photos and video recorded from my iphone.

Here are the steps for AirPlay:
Before starting Azul from your (running iOS 5.x/6.x) home screen where have have all your apps we need to turn on mirroring
On your iPhone 4S/5 or iPad 2 or 3, double-click the Home Button to view your recently-used apps.
Swipe all the way to the right to until you see the icon.
Note: If the icon does not appear, go to the "If AirPlay Mirroring is not visible or available on your mobile iOS device" section.
Tap the icon to see the list of available AirPlay devices.
Enable AirPlay Mirroring in this menu by tapping on an available Apple TV, then sliding the Mirroring slider to ON.
Now you should be seeing your iPad/iPhone on your TV.
Start up Azul now and using the settings icon on the top right corner go to the option that say "TV out" ON.
When you do that you will see an Orange screen
Now click "Done" and play the video you want to watch and it will AirPlay

Please Help::How to display a Map with LIsts as Keys and Values using JSTL

Hi,
I need some assistance on how to display a Map in JSP using struts or core JSTL. I have a HashMap which has a List of keys and each key maps to a value of an ArrayList.i.e I have an ArrayList of taxCodes and each taxCode maps to a value of taxDetails which is an ArrayList of details for for that particular taxCode. I have some trouble to display each taxCode then display taxDetails for each taxCode. Here is my code below:

hi evnafets,
yes i need a nested for loop.I have tried your advice but my bean properties are not found.Am getting this error:
javax.servlet.ServletException: Unable to find a value for "key_item" in object of class "java.lang.String" using operator "."
I have tried this as stated earlier in the post:I have tried to make the method getItemTaxDetails return a List and get the returned list value as taxDetails. I then tested to display this list on JSP and its displaying fine.

How to send object arraylist from servlet to jsp and display using jstl

Hi All....
I have a simple application and problem with it.
Once user logged in to system the user will redirect to LoginServlet.java controller.
Then in LoginServlet I want to redirect user to another page called book_details.jsp.
this is my login servlet.
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          // TODO Auto-generated method stub
          PrintWriter out = response.getWriter();
          ArrayList<BankAccountDTO> account_list = new ArrayList();
          ResultSet resultSet = null;
          LowFairAirDB airDB = null;
          try{
               airDB = new LowFairAirDB();
               String query = "SELECT account_id, type, description, balance, credit_line, begin_balance, begin_balance_time_stamp FROM bank_account";
               airDB.sqlSelect(query);
               resultSet = airDB.getResultSet();
               while(resultSet.next()){
                    account_list.add(new BankAccountDTO(resultSet.getInt(1),
                                                                 resultSet.getInt(4),
                                                                 resultSet.getInt(5),
                                                                 resultSet.getInt(6),
                                                                 resultSet.getString(2),
                                                                 resultSet.getString(3),
                                                                 resultSet.getString(7)));
          }catch(Exception ex){
          }finally{
               try{resultSet.close();}catch(Exception ex){}
               airDB.sqlClose();
     }I set bank account values to BankAccountDTO.java objects and add them to the arrayList.
Next I want to send this objects arrayList to books_details.jsp and wanna display each objects values using JSTL.
I still finding a way to go through this.
1. Can anyone say how can I do it?
2. Is there any other method to do the same thing without using JSTL?
thanks in advance,
Dil.

In your servlet,

Good. I would only follow the Java naming conventions. E.g. accountList or accounts instead of the ugly PHP/C conventions.
In the JSP,
lst = (List< BankAccountDTO >)request.setAttribute("account_list");
for(BankAccountDTO b: lst){
populate your HTML tags or whatever
Wrong. 1) You need getAttribute() and 2) you should not use scriptlets. Use JSTL c:forEach, e.g.<table>
    <c:forEach items="${accounts}" var="account">
        <tr>
            <td>${account.id}</td>
            <td>${account.type}</td>
            <td>${account.description}</td>
        </tr>
    </c:forEach>
</table>To the topicstarter: for future JSP/JSTL related questions please use JSP/JSTL forum.

Using JSTL to display space conditionally

Hi,
I need to use JSTL to insert a space when the value of a particular variable is null.
The obvious approach would be to use the following code:
<c:choose>
<c:when test="${var} != null">${var}</c:when>
<c:otherwise> </c:otherwise>
</c:choose>
OR
${var} <c:if test="$var== null}"> </c:if>
However, i need to do this in a lot of places ( a number of table cells to be precise) and the above code looks bulky to be inserted everywhere.
I read the JSTL documentation and found that the following code can also be used:
<c:out value='${var}' default=" " />
As per JSTL documetation, the default will be used if the variable has a null value and hence the above code should work theoretically.
My problem is that whenever the value of the variable is null, the output is and not a space. i.e. actually the text is displayed. Is there some way of getting the space to display?
Or is there any other alternative to condinally insert a space without having to write the bulky <c:choose> OR <c:if> code?
Thanks in advance.

My iPad 4 does not show up on my TV screen when in AirPlay mirroring mode using WiFi. The iPad displays AirPlay set to TV with the Mirroring On (green).
My iPad IOS software is 8.2 and my Apple TV software is at 7.1. The TV displays the Apple Menu. The “Settings” does however displays the General menu allowing me to see:
Apple software: 7.1 (7003)
Apple TV: Model No. A1464, Part No. MD199B/A
Signal Strength shows 5 circles.
It does not display the iPad screen but when I use the BT Sport App I can hear the sound but there is no video. I have searched the internet for a solution to no avail. The problem first arose when the IOS was at 8.1+ but it worked correctly briefly when I updated to IOS 8.2. Can you help please?

Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.
If you are still having problems, the following article(s) may help you.

Set Property to javaBean using JSTL

Hi all,
I have a custom object variable that I read from the session using JSTL.
<c:set var="someObj" value="${sessionScope.myObj}" scope="page"/>
Now i wan to set the obj into my JavaBean.
<jsp:useBean id="myBean" scope="request" class"ObjectA">
     <jsp:setProperty name="myBean" property="objA" value='????' />
</jsp:useBean>
How may I achieve this?
I've tried the following ways:
value = ${someObj}
value = '<c:out value=$"someObj">'
value = 'someObj'

How to to display entire records using PL/SQL(anoyomous block)

Hi All,
I have created a region of type PL/SQL by using rownum, and it wil display few records due to rownum.
But the end user is asking to display the rest of records also using some pagination concept or any other way.
How can we achieve this?
In mean time i have tried to execute the by removing the rownum, then it is throwing the below Query

How to devide the set of records into groups in SQL itself.

Hi , i am using 10.2.4.0 of oracle.
I am having one requirement, in which i have to devide the set of records into certain groups , so that they can be executed partly but not in one run.
So in the 'SELECT' clause itself i want to asssign particular value (may be 1 )to first 50000 records then another value(may be 2) to next 10000, like wise. And again the total count of records will also varry time to time , if the total count of record set is less than 10000 , then it should only assign '1' to all the records. i will set the group values (1,2,3...) as another column itself.
Can you please let me know if this can be done in SQL without going for PLSQL?

Hi,
That's called a Pagination Query , and here's one way to do it:
WITH     got_grp          AS
     SELECT     x.*
     ,     CEIL ( ROW_NUMBER () OVER (ORDER BY x_id)
               / 50000
               )          AS grp
     FROM     table_x x
--     WHERE     ...          -- If you need any filtering, put it here
SELECT     *               -- Or list the columns you want
FROM     got_grp
WHERE     grp     = 1
;ROW_NUMBER () OVER (ORDER BY x_id) assigns unique integers 1, 2, 3, ... to all all rows, in the same order as x_id (even if x_id is not unique).
CEIL (ROW_NUMBER () OVER (ORDER BY x_id) / 50000) maps the 1st 50,000 of those numbers to 1, the 2nd 50,000 to 2, and so on.
Analytic functions (like ROW_NUMBER) as computed after the WHERE clause is applied, so, to use the results in a WHERE clause, then you need to compute them in a sub-query. If you just want to display the number, and not use it in a WHERE clause, then you don't need a sub-query.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
In the case of a DML operation (such as UPDATE) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using.
