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.

You may try the paging taglib ...

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.

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'
But none of them works. Any suggestion? I do not wish to have any scriplets.
Thank you.

Here is an example of how to do it:
<%@page contentType="text/html"%>

    <c:out value="${firstBean.name}" />
    
    <c:set   value="newName" target="${firstBean}" property="name" />
    <BR><c:out value="${firstBean.name}" />
    <P>
Second bean :
    
    <jsp:useBean id="secondBean" scope="request" class="com.test.testBean"/>

        <c:out value="${firstBean.beanRef.name}" />
        
        <c:set   value="A completely new name" target="${secondBean}" property="name" />
     <br><c:out value="${firstBean.beanRef.name}" />
    </body>

</head>
and
<%@ page pageEncoding="UTF-8" %>
No improvement. please help me out of this.
how can i get arabic support in oracle AS by using jstl?
Thanks,

Only Apple Account Security could help at this point. You can try calling Apple Support in Canada - you'll have to find one of the several ways, such as Skype, to call an 800 number from outside of the relevant country - and ask for Account Security and see if they can help. Or you can find a friend who speaks Chinese and ask them to help you talk to Apple Support in China. There are really no other options that I know of.
Note, by the way, that these are user-to-user support forums. You aren't speaking with Apple when you post here.

How do I use jstl to insert links that passes sql info?

Hi all,
I'm using JSTL with sql and I want to create a link for every row so that the link would also contain the item in the first column of every row. But I keep getting stuck at saving the value. This is what I've tried:
<c:set var="myName" value="test" scope="page"/>
<tr>
<c:forEach var="row" items="${name.rowsByIndex}">
     <tr>
<c:forEach var="column" items="${row}">
     <c:if test="row =='uname'">
          <c:set var="myName" value="${column}"/>
     </c:if>
     <td>myName=<c:out value="${pageScope.myName}"/>"> <c:out value="${column}"/> </td>
</c:forEach>
</tr>
</c:forEach>
I either get a link of "edit.jsp?uName=$myName".
Any ideas would be appreciated.
Chris

Introducing the <c:url> and <c:param> tags!
<c:url value="edit.jsp">
<c:param name="uName" value="${myName}"/>
</c:url>Why the nested loops? When does row=='uname'? Could that ever occur?
If you are after a specific column why not have one loop over ${name.rows} and get ${row.uname}?
What server are you using?
What version of JSTL?
What is the taglib import you have made?

Invalid table name error when updating object in collection using SQL

Hi,
I have pl/sql code where I am selecting a object from a collection using sql select query. I am processing this record and now I want to update the collection with the new object. ie. ensure that the object that was fetched be removed and this new one be added.
considering my_ot is the object type and my_tt is the table type.
DECLARE
my_col my_tt;
my_col1 my_tt
my_var my_ot;
my_var2 VARCHAR2(10);
BEGIN
// populating my_col1 with select query
//populating my_col with select query
FOR my_col1.FIRST .. my_col.LAST LOOP
//populating my_var2
BEGIN
SELECT my_ot(c.field1, c.field2 ,c.field3) INTO my_var FROM TABLE(my_col) c WHERE c.field3 = my_var2
//processing the field my_VAR
UPDATE TABLE(my_col) c SET c.field1 = my_var.field1 , c.field2 = my_var.field2 , WHERE c.field3 = my_var.field3;
EXCEPTION WHEN NO_DATA_FOUND
my_col.EXTEND;
my_col(my_col.LAST) := // new my_ot object
END;
END LOOP;
Here, when compiling the update query is not being compiled. I am getting a error 'invalid table name'. Is there any way to modify an object in the collection without knowing its index?
If not, is it possible to find the index of a object in the collection in select query?
Thanks in advance
Paddy

Hi,
Is there any way to find the index of a object in the collection? Then I will simply replace the object at that index, right!
Thanks

How to count the length of a collection in JSTL?

Hi ,Everyone.
I want to count the length of a collection in JSTL.
For example:
<c:out value="${length(ownerList)}" />
the program compile wrong. Is length function supported in JSTL?
Thanks in advance!

Use:
<c:out value="${fn:length(ownerList)}"/>You'll have to include the functions taglib to use the function:

Using JSTL variables in JSP or Javascript. Possible ?

Hi All,
Is it possible to share or use the variables which are declared are used by JSTL in JSP expression or scriplet code and in Java Script.
Example:
This Works:
<fmt:set var="test" value="JSTL" />
<fmt:out value="${test}" />
But, this gives error:
<% out.println(test) %>
And passing the value of variable 'test' to Java Script code also gives error.
How to use JSTL variables in JSP and in Javascript ?
Yours,
Sankar.B

By default, JSTL variables are kept in servlet
attributes. Default is to store it in the page
context. You can make it request/session/application
scope as required by an attribute of the set tag.Hi there,
Can anyone advise how to access JSP variables in JSTL?
Can it be done as the same method through request/session/application scope?
Thnks...

But it is taking default as 8168, leading to HASH join between the tables..leading to FULL TABLE access.

I can use hints to use indexes but planning to avoid it as of now. Currently the time shown in explain plan is not accurate

Thanks Tubby,
While searching I had found out that we can use CARDINALITY hint to set statistics for TABLE funtion.
But I preferred not to say, as it is currently undocumented hint. I now think I should have mentioned it while posting for the first time
http://www.oracle-developer.net/display.php?id=427
If we go across the document, it has mentioned in total 3 hints to set statistics :
1) CARDINALITY (Undocumented)
2) OPT_ESTIMATE ( Undocumented )
3) DYNAMIC_SAMPLING ( Documented )
4) Extensible Optimiser
Tried it out with different hints and it is working as expected.
i.e. cardinality and opt_estimate are taking the default set value
But using dynamic_sampling hint provides the most correct estimate of the rows ( which is 2 in this particular case )
With CARDINALITY hint
SELECT
    /*+ cardinality( e, 5) */*
FROM
     TABLE
          SELECT
               CAST(TABLE_ESC_ATTACH(OBJ_ESC_ATTACH( 9999, 99991, 'file1.png', NULL, NULL, NULL),
               OBJ_ESC_ATTACH( 9999, 99992, 'file2.png', NULL, NULL, NULL)) AS TABLE_ESC_ATTACH)

Note
   - dynamic sampling used for this statement (level=2)I will be testing the last option "Extensible Optimizer" and put my findings here .
I hope oracle in future releases, improve the statistics gathering for collections which can be used in DML and not just use the default block size.
By the way, are you aware why it uses the default block size ? Is it because it is the smallest granular unit which oracle provides ?

I understand that the add row button is currently doing a submit.
To not submit the page you need a dynamic action on the page.
Does the javascript function addRow do what you want?
Otherwise have a look at the following two threads Add row in manual tabular form using dynamic action and Accessing Tabular Form & Add Elements to Collection without Page Submit.
You're process could be something like:
Add the new values to the collection using the idea's in the second thread and at the same time add the new row.
And as second action refresh your tabular form.
If you get stuck set up what you have done on apex.oracle.com using the tables from the demo application.

JSP Worked Well Using Scripting Elements, But, Becomes a Null Using JSTL

I have to bother all of you again with my JSTL problems. I am working on a JSP, which is very similar to the one that caused a lengthy discussion on this forum before. This JSP is a bit more complicated.
Again, this JSP worked well and displayed what I expected when the page was coded using the scripting elements.
I tried to use JSTL where possible and managed to correct all the compilation errors.
Now, I got a simple message: 'null' in the browser without any explanation - typical problem working with JSP: very difficult to debug.
I have tried to identify problems "one by one" and found the first encounter is where I want to set the background color for each row inside the <c:forEach ....> tag.
I examined the code again and again, I could not see what would lead to 'null'. I need a hand again.

Where is the null occuring? Have you looked at the returned HTML code to see where the 'null' is?
You might try just a few <c:out value=""/>, like:
The postRows = <c:out value="${postRows"/><br/>
<c:forEach var="postBean" items="${postRows"/>
The Current postBean = <c:out value="${postBean}"/><br/>
The Current parentPostID = <c:out value="${postBean.parentPostID eq 0}"/><br/>

<c:set var="background" value="#FFFFFF"/>
<c:choose>
    <c:when test="${postBean.parentPostID eq 0}">
      <c:set var="background" value="#FFCE9C"/>
    </c:when>
    <c:when test="${(i+1)%2 ne 0}">
      <c:set var="background" value="#EEEEEE"/>
    </c:when>
    <c:otherwise>
      <c:set var="background" value="#FFFFFF"/>
    </c:otherwise>
</c:choose>
The Background is now = <c:out value="${background}"/><br/>
<table width="95%" border="0" cellspacing="1" cellpadding="5" align="center" bgcolor="#999999">
    <tr bgColor="${background}">
    </tr>
</table>
</c:forEach>By adding output like that when we are debugging we can help track down where problems that occur are coming from. That and looking at the source code have been invaluable to me...

Link to summary report with filtered data set within FormsCentral

Is it possible to generate a link to a summary report with a filtered data set within FormsCentral?
If I have 4 sales agents each using the form to submit their repsective sales (with a dropdown indicating the sales agent) is it possible to filter the data so that only Sales Agent A see a report of their sales?
Thanks,

User selection to return filtered record set

Hi,
I want to create a JSP which allows a user to enter search criteria for several columns of a table. I will use the entered values to set the sql where clause and produce the filtered record set. (eg the user enters a particular customer code and status code in order to see a list of orders placed by that customer which have the selected status code.)
The problem I have is this: I want the input fields for the selection criteria to be combo boxes populated with values from the database.
What is the best way to do this?
