Pass paramters between jsp's

I have one combo box in the jsp page. on selecting an option, i want to call onchange method and process the selected index in a jsp/servlet with database locally and again redirect the resulted values to the current jsp page.
How to achieve the above task.
Please help
thanks

html:select property="comboboxName" styleClass="formfield" onchange='getCity()'>
</html:select>
<script language='javascript' type='text/javascript'>
function getCity() {
// write ur code
=================
my answer is
function getCity() {
document.mainform.action="pmTimeSheet.do?";
document.mainform.submit();
in the action class u need to filterout the required data from whole data
so u need to call action class in the function as shown in the above.

Urgent! pass parameters between jsp pages

Does anyone can give an example about how to pass parameters between jsp pages?
This is what I do:
pageContext.forward("pag_loginc.jsp?p_idusr=" + strUsr + "&c_password=");
But when deployed is not working.
Help is needed.

can you put that stuff in the session context in the first page, then pull it out in the second page?

Passing values between jsp and php

hi there, is it possible to pass values between jsp and
php? i really need to find out the way if there is
any. thanks in advance
-azali-

Yes, there are a few ways to do this.
1) Think about using Cookies.
2) Maybe use a Redirect passing the values in the Query string.
3) Retain the data in a repository in the back end.
4) Using Hidden fields within your pages.
I am sure you can use these Idea's for a base to develop other methods on how to pass values back and forth from JSP -> PHP and vice versa.

Process Flow - Pass paramters between activities

Need to pass argument from one mapping/component to next piece. What is the way. Process Flow Editor does not seem to show OUT paramters.
Pasting from a previous post
Hi,
I have a requirement to pass output parameter from a Mapping as input to another Mapping. These Mappings are tied together through a Process Flow.
Start Proc1 -> Map1 -> Map2 -> Proc2 -> End
Proc 1 will produce an output that will be used by Map1, and then Map1 will produce an oputput to be used by Map2, and so on till Proc2.
Also, Mapping Output Parameter is not showing up in the Process Flow.
What is the way to pass a parameter from one Mapping to next one one in a Process Flow?
Any answers are most welcome.

Hi,
What I have is a wrapper procedure that does a select from a control table. I would like to use this wapper procedure to drive the rest of the mapping by passing the parameter through the process flow.
It makes no sense to do the same select directly as this would be bypassing the wrapper/interface routine.
Would still prefer to have the ability to pass parameters between activities.
Would anybody who is presently close to OWB be in a position to answer that. It is important if we want to continue to use OWB to provide us benefits than headaches.

Pass value between JSP pages

I would like to pass values between pages.
I don't want showing up on the url. Ex: some.jsp?param=value
I don't feel it's safe.
It's not coming from form either....
How can I hide the value and pass it to next page?
I want to pass the value when the user click on a hyperlink
Thanks In Advance.

Client side information is never safe no matter what you do. If the values don't end up in the url, they are always present SOMEWHERE in the html content.
If you don't want the values to end up in the url, rework the page so it DOES do a post form submit. You could turn the hyperlink into a javascript call that submits the form for you.

Passing parameters between JSP and Servlet

The scenario is as follows:
There is a JSP page that sends a string as a hidden parameter to a servlet:
<input type="hidden" name=<%= Book.NAME %> value=<%= book.getName() %> >
In the servlet there is a print statement that checks the parameter value:
System.out.println("Book name: "+request.getParameter(Book.NAME));
The problem is as follows: if the name of the book consists of more than one word
such as "Servlets and JSP", the print statement will print only Servlet.
If the JSP page passes a string directly as shown here:
<input type="hidden" name="Test" value="Test String" >
The servlet will print the complete string: Test String
The same problem appears if the string is passed between two JSP pages.
Any help is greatly appreciated.
Regards,
Basil Mahdi

You might want to try
<input type="hidden" name="<%= Book.NAME %>" value="<%=URLEncode.encode(book.getName(), "UTF-8")%>" >This will take care of any wierd un-url friendly charcters that might appear in the book titles such as the ' or " which may be the problem.

Jsf passing parameter between jsp's

Hi
I have my main.jsp and another screen which i call object.jsp
the object.jsp can present an object in multiple ways : add, edit, view
i have 3 buttons in my main.jsp add, edit, view. I want to pass a parameter from main.jsp to object.jsp such that object.jsp will know in what state its being loaded... how do i do this?
Thanks..

session?
as the article says :
To avoid these problems, developers might use session-scoped variables instead. This fixes both of those problems, but adds new ones:
A single user cannot have two windows open simultaneously; session-scoped variables are global to the user. So, for instance, a user could not work with two different search results simultaneously.
Back button support is highly limited, since navigating back can't magically restore the session to its old state.

Passing parameter between jsp pages

Hi
I'v got the following problem: I have an jsp page that shows result of sql query as a list of 5 items, if there are more items returned - it shows first five, user is able to see more by clicking to a link which shows him the same page with next 5 items etc. The piece of index.jsp file with that link looks like that:
        <html:link action="<%=(String)request.getAttribute("actionMod")%> module=... name=... styleClass=...>and at the end of initSearchAction I have:
req.setAttribute("actionMod","initSearch.do");Action is defined:

        <action path="/initSearch"
                type="...list.InitSearchAction"
                name="productListForm"
                validate="false"
                scope="request"
                unknown="false"
                >
                <forward name="success" path=".search"/>
        </action>      .search is defined as
<definition name=".search" extends=".main">
        <put name="body" value="/list/index.jsp" />
</definition>The problem is when I set a paramter in initSearchAction like that:
req.setAttribute("handle",h);and try to read it next time when initSearchAction action is running, parameter h is null. I need that to pass handle to stateful session bean that holds important information that need to be static during a session. Can anyone tell me how to pass that handle in some other way?
regards
ania

now it works :)
I'm new to this things so I'm not familiar with all those sessions and requests...
thanks a lot

Passing parameter between JSP

Thanks in advance.

To pass value between jsp page

How can I pass hidden's value from a jsp page to other?
My code is:
a.jsp
<h:form id="insUser">
<h:inputHidden id="flag" value="1"></h:inputHidden>
</h:form>
b.jsp
<%String flag="";
flag=request.getParameter("flag");
out.print("flag="+flag);
%>
b.jsp shows: flag=null
Could you help me?

Because this hidden field id is insUser:flag, but not just flag.
If you have subview or other naming container(s) around form, the id name might be even longer.

Passing values between jsp pages

Hi all,
I am a newbie to jsp. I am trying to pass value from one jsp to another.
Let me post the code here and make my point clear. I have 3 jsp pages and am trying to get the value into my 3rd page that was in the first page.
This is my Test.jsp page:
<%@page contentType="text/html"%>
<html>
<head><title>Test JSP Page</title></head>
<body>
<%-- <jsp:useBean id="beanInstanceName" scope="session" class="package.class" /> --%>
<%-- <jsp:getProperty name="beanInstanceName" property="propertyName" /> --%>
Testing.. JSP Page
<FORM action='Response.jsp' method="POST">
<input type='Text' name='get_name'>
<input type="submit" value="Click Me">
</FORM>
</body>
</html>
This is my response.jsp page:
<%@page contentType="text/html"%>
<%@page import = "sun.jdbc.rowset.CachedRowSet" %>
<html>
<head><title>Response Page</title></head>
<body>
<%-- <jsp:useBean id="beanInstanceName" scope="session" class="package.class" /> --%>
<%-- <jsp:getProperty name="beanInstanceName" property="propertyName" /> --%>
Thank you... <%=request.getParameter("get_name") %>
// I want to pass this get_name to my next page, but since request.getParameter returns an object and not a string, how will I capture the value and pass it to my next page.
</body>
</html>
The 3rd jsp page is:
<%@page contentType="text/html"%>
<html>
<head><title>JSP Page</title></head>
<body>
// I am trying to get the value of the name here in this page.
<%-- <jsp:useBean id="beanInstanceName" scope="session" class="package.class" /> --%>
<%-- <jsp:getProperty name="beanInstanceName" property="propertyName" /> --%>
</body>
</html>
Your help is appreciated.
Thanks

Hi,
Thanks for the reply, it works. I was wondering whether this is an efficient way of doing this. What I want to do further is to setup a connection to a database and use the value I got from my previous page to query the DB and get the results and display.
I have see some code in the java website and a lot of people do by writting a bean /class(believe bean is just a class) and then importing it and do the things that way. I have good knowledge of OO and Java as a language and would definitely love to do it this way.
What i think i am missing is the basic idea to doing this way. So if you could let me know how to do this using java classes I would really appreciate it. If its too much to explain can u point to some good source(URL's) that explain's this. I have searched on this and all i find is code with no good explaination.
Thanks a lot

Pass values between jsp pages

Admin1.jsp
In this jsp page i have a drop down list with<select name=Update
From this page i move to the page Adnim2.jsp
Admin2.jsp
In this page i request for the value of selected entry in the drop down list as follows
String a=request.getParameter("Update");
From this page i move onto a servlet UpdateContribution.java
UpdateContribution.java
Here i need the value of the selected entry in drop down list ie Update
but String a=request.getParameter("Update"); does not work here and i get a Null Pointer Exception
Please help me

In Admin2.jsp, add a hidden form field and assign the selected value of drop-down to it. Now, you can obtain
the selected value of drop-down in Servlet(UpdateContribution.java) using given hidden form field.
Or,
Store the selected value of drop-down list in session. Now, you can obtain the value in servlet(UpdateContribution.java) through session

Passing values between JSP and Bean

I am trying to validate a date entered by the user on a form. I need to do an "alert" when the user enters a date outside of the valid range depending on a value entered in a drop down.
Am doing this in checkform function. Here is what I want to do:
1. Send the the value from the drop down and the date to bean to do the calculations. Call the EJB function from checkform.
2. Get a string values back into the jsp from the bean
3. Blow an error to the user to enter a valid date.
Any help in this case would be greatly appreciated.
Thanks.

I only see some design requirements.
What's the exact coding question? Where are you stucking while coding those requirements accordingly?

Pass user-defined Interfaces between JSPs

Communication between jsp and abstractportalcomponent

Hello All
Communication between jsp and abstractPortalComponent.
jsp contains one input text field and one submit button.
when the user clicks on submit button it will call the component and that input value will
display in same jsp page.
how this communication will happen?
Rgrds
Sri

Hi Srikanth,
In the JAVA File,
OnSubmit Event,
String inputvalue ;
InputField myInputField = (InputField) getComponentByName("Input_Field_ID");
if (myInputField != null) {
               inputvalue = myInputField.getValueAsDataType().toString();
request.putValue("textvalue", inputvalue);
request is IPORTALCOMPONENTREQUEST Object.
In JSP File,   to retreive the value,
<%
String textstring = (String) ComponentRequest.getValue("textvalue");
%>
In PORTALAPP.XML File,
<component name="component name">
      <component-config>
        <property name="ClassName" value="classname"/>
        <property name="SafetyLevel" value="no_safety"/>
      </component-config>
      <component-profile>
        <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
Using the code above, You can pass and read values between abstract portal component and Jsp Page.
Instead of this, I suggest you to use JSPDYNPAGE Component for Data Exchange.
