Passing variables to jsp

In what all ways we can pass variables to jsp??
I got one arraylist in my servlet(controller) and i have to send it to jsp page(view)...
one way of doing it is trough "session", is there any other way??
if yes .. which one is better??

Hi,
You can store your variable in 3 scopes in servlet and in 4 scopes in JSP
In Servlets you can do it in the following ways.
request scope
session scope
context scope
In Jsp you can do it in the following ways
request scope
session scope
context scope
and page scope
Request scope means, you can maintain the state only when the request is alive.
Session scope means, you can maintain the state only when the session is alive
similarly context , you can maintain the state only when the context is alive.
page scope is just for page.
I hope , you want these details. :)
bye for now

Passing Variables from JSP to a servlet

Presently I have a small Web application where by users enter data onto a jsp Page , this data then gets passed onto a servlet which then updates a sql database through a call to a sql stored procedure
While testing I determined that when there are multiple users, sometimes users records are getting crossed, some of my data, is getting written to someone elses record....
any thoughts on the cause......

below is the code to the servlet
The jsp page is a typical jsp with text boxes etc,
package cpri;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.sql.*;
public class viewfileinfoservlet extends HttpServlet {
private static final String CONTENT_TYPE = "text/html";

public void init() throws ServletException {
//Process the HTTP Post request

i dont need to link it together with as xml as ive already done so in ratios.xsl file... i think there might be some mistake in using the include code... can anyone point out to me if im wrong... thanks

Open AirPort Utility on the PC, select the Airport Extreme and click Manual Setup
Click the Advanced icon
Click the Port Mapping tab
Click the + (plus) button at the bottom of the connection list to set things up
Reference pages 49-51 in the Apple AirPort Networks guide for more info
IF.....you do not see a Port Mapping tab when you click the Advanced icon, then that would mean that the AirPort Extreme is in Bridge Mode and the main routing functions for the network are being provided by another device.
You will need to set up the port mapping on that device, which is likely your modem/router or gateway.

How to pass javascript variable to jsp function

i want to check which table header (that is <th> in html )is clicked and based on that a jsp funtion do a query in database and should show records in sorted way according to which column head is clicked.
Table is created in html.
My function is
Vector varray = workcaseid.getWorkcaseId(Long.parseLong(MasterAccountNumber),SelectedColumn);
<table border="1">
<th ><label onClick="<%SelectedColumn="workcase_id";%>">Workcase Id</label></th>
<th><label onClick="<%SelectedColumn="status_id";%>">Status</label></th>
<tr><td>etc</td></tr>
</table>

im using bean for business login, following mvc model,and i think mvc is one of good design practice to use.
<jsp:useBean id="workcaseid" scope="session"class="beanFiles.SearchWorkcaseId" />
varray = workcaseid.getWorkcaseId(Long.parseLong(MasterAccountNumber),SelectedColumn);
just tell me whether it is possible to pass javascript variable to jsp variable or not.i can do it by using hidden input type,using form and submit button.

Passing variable from one JSP to another

Hi....
I am working on customizing Oracle Application(istore).
I need to pass variable from 1 JSP to another.
JSP 1 contains the following line of code:
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
How can I pass this to another JSP Page. The other JSP should take the 'soldtoCustPartyName' and find out the primary address country.
So please help me in getting variable passed from 1st JSP to next.
By default, 1st JSP is not fwded to 2nd JSP.
This is very very urgent...Please help.....

When you push the submit button on jsp1 - it goes to jsp2?
ie
// in jsp1.jsp
<form action="jsp2.jsp">
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
<input type="submit">
</form>
//Then in jsp2.jsp all you need is
request.getParameter("soldtoCustPartyName");This will pick up the value that is coming from the hidden field on jsp1

Passing variables between data tag and JSP-scriptlets

Hi,
There were some questions about this issue. However, the answers were not satisfactory.
I would like to assign the value returned from data tag to a variable in JSP-scriptlets as follows:
<%@ taglib uri="/webapp/DataTags.tld" prefix="jbo" %>
<br>
<jbo:ApplicationModule id="isae.OPKv1.OPKv1Module" configname="isae.OPKv1.OPKv1Module.OPKv1ModuleLocal" username="t1" password="t1"/>
<br>

<jbo:DataSource id="ds" appid="isae.OPKv1.OPKv1Module" viewobject="AePk100View" whereclause=" <%= ic %> " />
<br>
<jbo:Row id="privRow" action="CURRENT" datasource="ds">
<%
String privName = (String) privRow.getAttribute("ArBau325"); // this is the suggestion of William Dwight (Jan 21, 2001 this forum)
%>
</jbo:Row>
This code did not work. I have obtained an error :
java.lang.ClassCastExeption
Any help would be greatly appreciated.
Thanks

The value return by the getAtribute might not be of type String. If you want to return a String value you need to convert the value using the toString method as follow:
<jbo:Row id="privRow" action="CURRENT" datasource="ds"/>
<%
String privName = "";
Object obj = privRow.getAttribute("ArBau325");
if (obj != null)
privName = obj.toString();
%>
Also note that you do not need to put the scriplet code inside the body of the row tag.

How can i assign a Javascript variable to JSP variable

Hi guys
how i can assign a javascript variable to jsp expression.,
e.g.,
<input type = "button" value = "Add more" onclick = "return submitform1('<%=s%>')">
function submitform1(String s)
      var s1 = s
document.form1.action = "../intimation.do";    /* Here i want to pass the value s1 to jsp or servlets without using hidden fields and Query string*/
       document.form1.submit();
      return false;
/* i want to pass the values thru session whether it is possible */
pls give sample code

You don't have the session.
All you have is HTTP.
The only way to communicate from the client to the server is via an HTTP request. The only way to send a value like that is with a parameter.
Using a form with method="submit" as mentioned will pass the parameters without displaying them in the url bar (is that what you wanted?)

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...

Equating a passed variable to another variable??

I have a simple 3 part setup as follows...
1 JSP, 1 Java Class, 1 Interface for the class
I want the JSP file to pass a variable to the java class which contains the name of a variable in the interface. (e.g. a String called "name", the variable name in the interface contains "Bob Smith") How do I get java to equate what is in the passed variable ("name") to what is contained in the name variable of the interface("Bob Smith"). Hopefully I explained this with enough detail to understand, but if I didnt, let me know.

Nevermind, I'm going to switch the flow of data so I dont have to do that.

Hi all,
Thanks for your quick response.
So u are right that we can not call javascript variable
in the same JSP. and pass them to the bean class.
So what I did --- I get java script variable in another JSP using
request.getParameter(); and then redirected to previous JSP.
and I have solve my problem.
Actually I had to call bean class and pass varible to the bean
method but I was getting the same problem that I disscussed but now it
has been solved.
Thanks again for participation

Passing variable values to the navigation block

Hi WAD Experts,
I have a requirement regarding passing variable values to the navigation block. User requirement is first give the selections on the selection screen and then after executign output should display in browser. In the output page we have a navigation block. So when user gives selections those selections should also populate in the navigation block. Your help will be appreciated.
Prasad.

Hi,
if your variable is 'Changeable at Query Navigation' the chosen values will appear in the Navigationblock.
Variables which are 'Not Changeable at Query Navigation'
will not appear.
You can set this Property when you create a Variable.
Kind Regards,
