How to deal empty field with jsp:setProperty ...

Ive come across a bug in what I've done so far, not sure if its because of my approach...
I sucessfully store a value entered in a text field in a bean without any problems, and navigate back to the page where the value re-appears (via html, not relying on the browser). The problem is, if I edit that field to be blank, resubmit, then navigate back, the old value returns.
As far as I can tell, this is due to my jsp interpreting the input as null (ie. no input) and not changing the tag. IE sends the parameter as myPage.jsp?para1=&para2=some+value as it should (where para1 is the input in question).
I use the 'parameter="*"' usage of jsp:setProperty - is that a problem? Does this usage of setProperty not allow for setting values back to "" ? If so, how can i overcome this problem without losing the benefits of using <jsp:setProperty name="myBean" property="*">, that is, you can store all property values in javaBean in one go, instead of repeatly using <jsp:setProperty name="myBean" property="myProperty" value="myValue"> for each property.

hi,
first clearly tell u' r problem and then only any one can help u.
we are not unable to understand u'r query. it's like a Composition.

Modify Collection with jsp:setproperty

Hello:
I have a problem with jsp and struts.
I have a collection of items (List) and view the elments in jsp page. This It works fine.
But the problem happens when i like modify the collection.
The code to view the collection in jsp is:
<jsp:useBean id="ItemListForm" class="com.myapp.struts.ItemListForm" scope="session" />
<html:form action="/ItemEditAction" >
<logic:iterate name="ItemListForm" property="listaItems" id="item" >
<P>
<BASEFONT SIZE="3">
<jsp:getProperty name="item" property="etiqueta" />
</BASEFONT>
<P>
<jsp:getProperty name="item" property="grafico"/>
<P>
</logic:iterate>
<P>
<html:submit>Save File</html:submit>
<html:hidden property="do" value="saveXML"/>
</html:form>
The question is:
How to modify the element "grafico" with jsp:setproperty.
Thanks for all.

Thank you, I had forgotten the set part, but then the next problem occurs:
<jsp:setProperty name="date" property="locale" value="${locales.locale}"/>
generates:
org.apache.jasper.JasperException: Unable to convert string '${locales.locale}' to class java.util.Locale for attribute locale: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
could I only use Strings as input?

How to create a field with 1200 chars length

Hi,
Will anybody let me know how to create a field with length 1200 in a table.
Regards,
Madhavi

Hi Madhvi,
Other thing what you can do is
1. First create a Table type.
Goto SE11-> Dataelements ->Table type
There on the next screen select Predefine radio button & there provide data type & size.
2. Create a structure having a field typa of Table type created before. say that field is quant.
Now in your program refer that structure to create an internal table & work area.
Now if u append ur text to the field quant.
try creating line type of size more that 255 if it works then fine other wise reduce it.
Note:: This will be a deep structure.
so first append value to the field quant, the at the end of first record append valu to ur internal table.
thanks

Replace the empty field with below data content field in xml pub report

Hi Gurus,
Please give me the solution for the Replacement of empty field with below data content field in XML PUBLISHER REPORT.
ex:
Name:Philips.M
Address 1:XP APPTS,
Address 2:S:R ROAD
Address 3:
COUNTRY:INDIA
Here i have to get only address 1,address 2 and the COUNTRY data.I dont want to display Address 3 field here.
Thanks,
David

I'm not sure if this answers your question but you could try putting out the address all in one item in the SQL eg somthing like:
address1 || DECODE(address1, NULL, NULL, 'newline character') ||
address2 || DECODE(address2, NULL, NULL, 'newline character') ||
address3 || DECODE(address3, NULL, NULL, 'newline character')
where 'newline character' is somthing like CHR(12)

Need Help: Problem with JSP setProperty to Bean

Hi,
This is my first time posting to this forum so I am not completely aware how Duke dollars work but if anybody can help me I will be happy to give some... whats normal for solving a problem?? 10??
Anyway... the problem...
I have a simple JSP with a simple HTML <form> that has a text field and a Submit button. Submit takes the user to the next JSP page however the setter method for property 'user' is never called. I can verify this through an attached debugger.
I am using Tomcat 5.5, and I never had a problem like this in previous versions of Tomcat.
I have tried changing the scope of the bean to request however nothing changed. I excluded all my business logic and tested this one more time just to make sure I wasn't inadvertadely screwing with something however this still does not work.
I am sure I am missing something small but for the life of me I can't figure out what.
Here is my code:
index.jsp
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <jsp:useBean id="something" scope="session" class="com.db.servlet.UserBean">
            <jsp:setProperty name="something" property="*"/>
        </jsp:useBean>
        <p>Select</p>
        <form id="Form1" method="post" action="multi.jsp">
            <p>User: </p>
            <input type="text" name="user" size="20"><br>
            <input type="submit" value="Submit">
        </form>
    <br><p>Or select Single mode.</P><br>
    <a href="tris.html">tris</a>
    </body>
</html>UserBean:
package com.db.servlet;
public class UserBean {
    private String user = null;
    public UserBean() {
    public void setUser(String user) {
        this.user = user;
    public String getUser() {
        return user;
}

Oops!
I not only realized my mistake, I also accidentally posted this in the wrong forum. I meant to post in the JSP Forum.
For reference, what I did wrong was I placed my setProperty tag in index.jsp rather than placing it in multi.jsp (the file specified in the form action).
Everything works now.

Prob with jsp setProperty

Dear fouramites,
I am using jsp SetProperty standadr action tag to set from values to beans. In update when I am changing any form field value it is working fine but when I am deleting the form field value the previous value is being set to bean.
What is the solution to this problem?
Thanks & Regards
Kavyaanjali Jena

Dear Ram,
I am using the following code for both save and update functionality.
<html>
<%@ page session="true"%>
<%@ page language="java" %>
<%@ page import="models.*"%>
<%@ page import="beans.*"%>
<%@ page import="java.util.*"%>
<%
<jsp:useBean id="DATA_MODEL" scope="session" type="models.BeanInterface" />
<jsp:setProperty name="DATA_MODEL" property="*"/>
<jsp:forward page="/servlet/FrontController" />
</html>
When I change the value This code could set value to bean but when I totally delete the value it could not set null to bean but old value is retained.
I am using FrontController architecture.
Thanks & Regards

How to fetch all fields with RFC_READ_TABLE ?

I can use RFC_READ_TABLE to fetch specified fields with the TABLE parameter "FIELDS". If I want to fetch all fields of the table, I must specified each field name. However, I can not use "*" in FIELDS, and I can not left the table empty (Error will be generated). Is there other method to fetch all fields ?
language: VB.NET
tblT = New TAB512Table
        tblTField = New RFC_DB_FLDTable
        tblTOption = New RFC_DB_OPTTable
        Dim stuTFieldRow As New RFC_DB_FLD
        Dim stuTOptionRow As New RFC_DB_OPT
        Sapproxy.Rfc_Read_Table("", "", strTN, 0, 0, tblT, tblTField, tblTOption)

Hi:
Do like this
CALL FUNCTION 'RFC_READ_TABLE'
EXPORTING
query_table = Table
delimiter = ''
no_data = ''
rowskips = 0
rowcount = 0
TABLES
options = i_options
fields = i_fields
data = t_data.

You might want to look at using a Java Bean wrapper, this can be done automically using WebSphere. It creates what is called an access bean which the JSP imports.

How to get two fields with same tech name in LIS Extractors?

Hi Experts,
I need "ERDAT" field from two structures (QMSM & QMFE) in 2LIS_18_IOTASK extractor.
In LBWE first I moved ERDAT from QMSM. When I moved ERDAT from QMFE it gives an error:
"Field with same technical name is already available in the Extract Structure".
I don't want to create Append Structure as we need to write User exit.
Can any one tell me how to get this field added in the extractor from QMSM and QMFE?
Thanks for your help.
Regards,
Sree

this is not possible as the all those fields are put in one structure. per definition you can't put the same field name twice in a structure, table in the data dictionary...
hence, you really need to use an append and fill via user exit

How to count ONLY fields with a specific value

I modified the code below from the API reference to count combobox fields with a value of "MT" so I could total the number of a specific choice the form user input.
var count = 0;
for (var i=0; i<this.numFields; i++)
var fname = this.getNthFieldName(i);
if ( this.getField(fname).type == "combobox" && this.getField(fname).value == "MT" ) count++;
this.getField("mTurb").value = count.value;
Here's the problem: I tried to use a similar script, modified only slightly from this form, in another total field to tally a different choice made with comboboxes and the script continues to tally the first choice. An example of one of the modified versions of the script is below.
var gcount = 0;
for (var i=0; i<this.numFields; i++)
var gname = this.getNthFieldName(i);
if ( this.getField(gname).type == "combobox" && this.getField(gname).value == "MT" ) gcount++;
this.getField("gPack").value = gcount.value;
I suspect I'm just missing something painfully obvious to seasoned scripters, but I can't seem to figure it out and I need this script to be able to count the number of 9 different options in the comboboxes.

OK, you can use a script like the following as the custom calculate script for the text fields that perform the counts:
// Custom calculate script for text field
(function () {
    // Declare and initialize variables
    var fn, s = "MT", count = 0;
    // Loop through the combo boxes
    for (var i = 1; i < 25; i++) {
        // Determine the current field name
        fn = "M" + util.printf("%02d", i));
        // See if the field value matches
        if (getField(fn).valueAsString === s) count++
    // Set this field value to the count
    event.value = count;
Change the value of the "s" variable to match the item that you want to count. The first and last lines prevent the unnecessary creatio of global variables, which is good. It also makes it easy to transfer to a more general document-level routine, which would be event better, something like:
// Custom calculate script for text field
function getCBCount(s) {
    var fn, count = 0;
    // Loop through the combo boxes
    for (var i = 1; i < 25; i++) {
        // Determine the current field name
        fn = "M" + util.printf("%02d", i));
        // See if the field value matches
        if (getField(fn).valueAsString === s) count++
    // Set this field value to the count
    event.value = count;
You would then call this function from the individual text boxes with the following custom calculate script:
getCBCount("MT");
and replace "MT" with the vlaue you want to count.

}This script i am calling on, onchange() for the select list item P3_CHANNEL and it is working fine.
But i have a create button and cancel button.
After filling the details in the required columns, when i click the create button, if any validation errors are there.. the page is re-rendered. while doing that the hidden items are getting displayed back.
Tried Solutions:
1. I created a same function once more and in the last added the doSubmit('CREATE') and called the script from the create button.
At that time the hidden fields labels are getting displayed.
2. I created a process On load before header To call this script on a condition :REQUEST = 'CREATE'
Then also fruitless..
I hope now it is clear....
Please! Any suggestion are mostly appreciated.
Thanks in advance

How to update TASK_hyperlink_address field with PSI?

Simple question but hard to do.
Can we have custom fields with html hyperlink?
And why having fields read only ????

Enterprise Custom Fields do not support Hyperlinks. You can use the HREF standard task field for this purpose.
