Assigning Bean to a jsp variable

The following is code for my bean:
package com.brainysoftware;
public class CalculatorBean2{
private int memory1;
private int memory2;
public void setMemory1(int number) {
   memory1=number;
public int getMemory1( ) {
   return memory1;
public void setMemory2(int number) {
   memory2=number;
public int getMemory2( ) {
   return memory2;
public int doubleIt(int number) {
return 2 * number;
public int CombineIt(int number1, int number2) {
return (number1+number2);
public int HalfIt(int number) {
return number/2;
}And the jsp is given below:
</HEAD>
<BODY>
<h1>Using the CalculatorBean2</h1>
<jsp:useBean id="theBean" class="com.brainysoftware.CalculatorBean2" />
<jsp:setProperty name="theBean" property="memory1" value="10"/>
<jsp:setProperty name="theBean" property="memory2" value="20"/>
The value of memory1 is <jsp:getProperty name="theBean" property="memory1" />
The value of memory2 is <jsp:getProperty name="theBean" property="memory2" />
<%
int memory1= theBean.getMemory1 ( );
int memory2= theBean.getMemory2 ( );
%>
The combine value of memory1 and memory2 is <%= theBean.CombineIt(memory1, memory2)%>The above is working fine but when I am assigning value to jsp var through bean tags, its not working:
<% int mem1= %> <jsp:getProperty name="theBean" property="memory1" />
<% ;
int mem2= %> <jsp:getProperty name="theBean" property="memory2" />
<%; %>
The combine value of memory1 and memory2 is <%= theBean.CombineIt(mem1, mem2)%>
</BODY>
</HTML> Can somebody plz help me with this?

Help: How to assign dynamically a javascript variable to a jsp variable???

Hello all,
What I need to do is to assign the value of the html form element which is a checkbox in this case:
<input name="ADB02_checkbox" type=checkbox id="ADB02_checkbox" onClick="decide_enable_or_disable_particular_checkbox()" value="ADB02">
to a jsp variable :
<%
String riderCode = "";
%>
Its dynamic because i need to do different operations based on different rider codes like in this function:
function decide_enable_or_disable_particular_checkbox() {
var rider = document.rider_form;
alert(rider.ADB02_checkbox.value);
if (rider.<%= riderCode%>_checkbox.checked == true) {
enable_all_row_elements_for_<%= riderCode%>();
else {
     disable_all_row_elements();
which uses the naming of the rider code to call other corresponding functions.
so is there any way that you guys ca suggest a solution.
what i thought is to do this:
function decide_enable_or_disable_particular_checkbox() {
var rider = document.rider_form;
HERE--> riderCode = rider.ADB02_checkbox.value;
alert(rider.ADB02_checkbox.value);
if (rider.<%= riderCode%>_checkbox.checked == true) {
enable_all_row_elements_for_<%= riderCode%>();
else {
     disable_all_row_elements();
or
add an onFocus="riderCode = document.rider_form.ADB02_checkbox.value;" in the checkbox tag.
but can i do that or is there any other way or is it totally impossible to assign javascript values to jsp variables.

Hi again,
I got a problem here abt looping in javascript.
The prob is that only the 1st loop works the rest are not.
So only the checkbox in the 1st row is enabled, the rest aren't.(only ADB02 is enabled not DLP01 cause ADB02 is 1st in the loop)
Here are 2 of many of the checkboxes in different rows:
<input name="ADB02_checkbox" type="checkbox" id="ADB02_checkbox" value="checkbox" onClick="val_checkbox()" disabled=true>
<input name="DLP01_checkbox" type="checkbox" id="DLP01_checkbox" value="checkbox" onClick="val_checkbox()" disabled=true>
This is declared in jsp:
<%
//to be used with javascript function prepare_elements() for checking to enable/disable checkbox , to check age base and limit of insured
String[][] riderCheckArray = {
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_ACCIDENTAL_DEATH_BENEFIT, "20", "60"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_LIFELINE_BENEFIT, "20", "50"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_MEDICASH_100_PLAN, "0", "55"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_MEDICASH_200_PLAN, "0", "55"},

{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_MANUTERM_REDUCING_TERM_ASSURANCE_PLAN, "16", "65"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_PERSONAL_ACCIDENT_BENEFIT, "20", "65"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_15_YEAR_LEVEL_AND_CONVERTIBLE_MANUTERM_RIDER, "16", "55"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_20_YEAR_LEVEL_AND_CONVERTIBLE_MANUTERM_RIDER, "16", "50"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_5_YEAR_RENEWABLE_AND_CONVERTIBLE_MANUTERM_RIDER, "16", "60"},
{allPlans.PLAN_HER_MY_FUTURE, allRiders.RIDER_10_YEAR_RENEWABLE_AND_CONVERTIBLE_MANUTERM_RIDER, "16", "60"},
%>
Here's the script (the riderCheckArray[any no.] should be eg: riderCheckArray[0] (has an i in front))
<script>

function prepare_elements() {
var rider = document.rider_form;

for (i=0 ; i < <%= riderCheckArray.length%> ; i++) {
if ("<%= txtPlanCode%>" == "<%= riderCheckArray[i][0]%>" ) {
riderCode = "<%= riderCheckArray[i][1]%>";
if (<%= insuredAge.intValue()%> < <%= Integer.parseInt(riderCheckArray[i][2])%> ||
<%= insuredAge.intValue()%> > <%= Integer.parseInt(riderCheckArray[i][3])%>) {
disable_particular_checkbox();
alert("This rider cannot be attached. This rider can only be attached for age range " +
<%= riderCheckArray[i][2]%> +
" to " +
<%= riderCheckArray[i][3]%>);
else {
enable_particular_checkbox();

function enable_particular_checkbox() {
var Rdr_Checkbox = riderCode + "_checkbox";
var rider = document.rider_form;
rider.all(Rdr_Checkbox).disabled = false;
rider.all(Rdr_Checkbox).style.background ="FFFFFF";
function disable_particular_checkbox() {
var Rdr_Checkbox = riderCode + "_checkbox";
var rider = document.rider_form;
rider.all(Rdr_Checkbox).disabled = true;
rider.all(Rdr_Checkbox).style.background ="CCCCCC";

How to get javascript variable in jsp variable

Hi all,
i have a variable str in my javascript function
var str = somevaluei want this str value in jsp variable in the same page...
how can this be done..???
any ideas...
Thanks

I dont know if its possible or not.
Actually it depends on what do you want to do with the variable.
as far as assisginng value to the hidden variable is concerned it can be done this way.
<% jsp code
String hiddenVar = "";
%>
< html code
<input type type = "hidden" name="hidden" vale="<%=hiddenVar %>"
html ends>
while in js function you can assign vale to the hidden variable which will ultimately assign value to the JSP variable as follows.
var str = "value";
document.form_name.hidden_field_name.value = str.
hope this hepls.

Assining a bean attribute to a jsp variable

I am writing a struts application and am using
<bean:write name="configattribute" property="name"/>
to print out info on my jsp page.
I was wondering if I could assign that value to a local jsp variable so I can check its value and change the colour of the text accordingly.
e.g.
String name = <bean:write name="configattribute" property="name"/>;
if name.equals("Ben"){
out.print(<font color=\"red\">;
else{
out.print(<font color=\"blue\">;
}

You should still be able to use the code I listed...the logic:iterate tag creates the bean "configname" in the page scope. So you should be able to do something like this:
<logic:iterate id="configname" name="confignames">
   <tr>
      <td>
<% ConfigName configname = (ConfigName)pageContext.getAttribute( "configname" );
   String color = "blue";
   if( "julius".equalsIgnoreCase( configName.getOwner( ) ) )
      color = "red";
   } %>
        <span style="color: <%= color %>"><bean:write name="configname" property="owner"/></span>
      </td>
      <td>
         <bean:write name="configname" property="name"/>
      </td>
   </tr>
</logic:iterate>Does that sound right?

Assigning html input value to a jsp variable

I have the following problem: I need to assign the value of html <input> field to a jsp variable. This should be done without submittion of the form.
<form name="main">
<table>
<tr>
<td><input type="text" name="gantry" value="123"></td>
</tr>
<table>
</form>
Is there any way to access main.gantry.value from jsp and assign it to a variable? I tried
<% prevGantry = main.gantry.value; %>
but it didn't work, and the problem is not with parsong or initialisation. Please, can anyone help?
Best regards, SoVa.

No it can't be done. You are mixing up java with javascript.
Java/JSP runs on the server end. Generates an HTML page and stops running.
The page loads in the browser, and and can run javascript locally.
The only way to run java code again is to go through the request/response process. ie submit a form, click a link, make an Ajax call...
The only way to get a field from the screen into a java variable is via request.getParameter().

Assigning a javascript value to a JSP variable

How do i assign a javascript value to a JSP variable?
eg
<%
String JSPvar;

Unable assign a BPM Object field value to a JSP Variable using "invoke"

Hi,
I'm unable to retrieve a value returned by a BPM Object Method and use it in JSP. Here is what I'm trying to achieve:
BPM object named : "myObject" has a method "getRequiredValue" which returns a "String". I want to assign the value returned by "getRequiredValue" to a JSP Variable "myVariable" using invoke method as below:
<% String myVariable = ""; %>
<f:invoke var="${myObject}" methodName="getRequiredValue" retAttName="myVariable"/>
<% out.println ("myVariable: " + myVariable); %>
When I execute the above code I don't get the value being returned by "getRequiredValue" into "myVariable".
Any help would be highly appreciated!
regards,
MK

1. Make sure you mark the "Server Side Method" property of the getRequiredValue method to "Yes".
2. I guess you dont need to specify "<% String myVariable = ""; %>". Try removing it.
3. Replace "<% out.println ("myVariable: " + myVariable); %>" by <c:out value="${myVariable}"/> just in case!
4. Lastly, I hope "myObject" is the name of the instance variable in your screenflow, and not the BPM object name.
Hope this helps

I want to assign the value of a Javascript variable to JSP Variable

I want to assign the value of a Javascript variable to JSP Variable .. for example :
<%
Bla Bla Bla
%>
<script>
var JavaScriptVariable="hello"
</script>
<%
String JSPVariable=// The Value of JavaScriptVariable ;
%>
How can i do that ??
Thanks

>I want to assign the value of a Javascript variable to JSP Variable
cannot be done.Friend try to understand concepts properly Javascript is always excuted by the browser @clientside where as JSPCode is executed Websever(ServletContainer) @serverside.Through you are combining JSP Code blocks(Tags,Expressions,scriptlets...) & javascript under a single page webserver can only identify what is their under JSP Code blocks.
Hope this could be an appropriate answer for your question.
However,you can as well submit a request by encoding your URL with request parameters and the submit to the page and then collect it using request.getParameter(name).
But under a single context state it is not possible

here i want to set value of a JSP variable qq to session scope and here i am not invoking any servlet i want value of qq in next JSP page i am not submitting the page so how i can handle this. this code does not work so please tell me how to do this i am using struts frame work

if you are using the struts framework, then you can make an ActionForm with getters and setters for the stuff that you are writing in the JSP i mean the radio buttons and text boxes etc
from that action form you can get the values any time any where
you just need to enter some thing like below in the struts-config.xml file
<form-bean name="the action form name" type="package name.Actionform name" />
<action path="/controller " type="package name.controller name" name="Action form name" scope="session">
you can either put the action form in request scope or session scope

Assigning bean property to custom tag's attribute

1. The #{beanName.property} notation can only be used inside JSF tags.
2. The attributes of custom tags does not accept embedded tags.
e.g. <prefix:tagName attrib1="<jsftag>">
I need to assign a bean's property to the attrib1 attribute. how do I do this?

Alternatively, how can I assign the value of a bean property to a variable?
e.g.
<%
int var=<bean.property>
%>
I can use the variable on the custom tag like this:
<prefix:tagName attrib1="<%=var%>"> OR
But this may not be the best solution though because I have to use scriptlets...

Accessing JSP variables in Included Javascript

Hey All,
I want to hide my javascript to be viewed on the client browser.
I know we can do that with the javascript include ,But i am using JSP variables in
Included javascript.I can't access those variables any more.
Does anybody know any workarround.
Thanx
Vijay

Hi Vijay,
I am also facing the same problem of hiding javascript in the client browser. My javascript variables are getting initialised on the fly using JSP. Since JSP is compiled on the server side, one can't compile .js file on the client side.
What u can do is to divide your page into frames with
<frameset rows="100%,0%">. Now put your form hidden fields or the .js file in frame 2 which is not visible to the user and then assign your jsp variables in the frame2 html/jsp page. Now access your variables from frame2 in frame1 using
var i = parent.frames[1].document.forms[0].elements[0].value
Assuming that there is 1 form and 1 hidden field in frame2 html/jsp page.
I hope u get the logic rite....
I had done it for application but problem is that our users are real MORONS and they keep doing ctrl+F5 which takes them to the Indexpage.
If you get some other solution then please mail it to my email address
[email protected]

Can i assign a string to a variable in User Exit?

Friends,
I would like ot write a User Exit that will assign a string to a variable depending on the value of the other variable.
I just wanted to know if such a code is valid:
When zimport
IF i_step = 2.      " read user input parameter
        l_s_range-low = 'Important'.
     APPEND l_s_range TO e_t_range.
    ENDIF.
If so, my second problem is that in the variable exit definition with processing Customer type you need to identify a "Dimension" for the variable. Non of them really fit, because the value is a string so why convert it to another format?
Your input is appreciated in advance,
Xibi

hi Xibi,
say you have var1 and var2, var2 will be filled depend on value of var1, you can write something like following.
please be remind that var2 is not marked as ready for input and is set to mandatory variable entry.
hope this helps.
The second step (I_STEP = 2) is called after the processing of the variable pop-up. This step is called only for those variables that are not marked as ready for input and are set to mandatory variable entry.
WHEN 'var2'.
    IF I_STEP = 2.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
              WHERE VNAM = 'var1'.
        CLEAR L_S_RANGE.
        if LOC_VAR_RANGE-low = ...
