Pass ArrayList to jsp and display first index of resultset?

Is it possible for me to pass an ArrayList to a jsp, and display the each resultset stored in the ArrayList by the ArrayList index?
The code below gets passed two paramaters. An invorg, and item. It then creates resultset based upon the Object and puts the results into an ArrayList.
The resultset returned varies, but the largest resultset that I have received back has not been bigger thatn 10 resultset rows, and the largest number of columns has been 27 columns.
I would then like to pass the whole ArrayList to the jsp and display the contents for each row based on the index it is on.
Is this possible?
public class RunReportAction extends MTDAction
 ArrayList results;
 public RunReportAction()
 public boolean execute(HttpServletRequest _req, HttpServletResponse _res) throws ServletException, IOException
 String item = _req.getParameter("itemsToAdd");
 String invorg = _req.getParameter("invorg");

Your arraylist object should be a list of inventory bean objects and then, If you are using struts, you could use logic:iterate tags.. or something equivalent.. you could use forEach in jstl..

How to pass arraylist of object from action class to jsp and display in jsp

I need to do the following using struts
I have input jsp, action class and action form associated to that. In the action class I will generate the sql based on the input from jsp page/action form, create a result set. The result set is stored as java objects in a ArrayList object.
Now I need to pass the arraylist object to another jsp to display. Can I put the ArrayList object in the request object and pass to the success page defined for the action? If this approach is not apprpriate, please let me know correct approach.
if this method is okay, how can I access the objects from arraylist in jsp and display their property in jsp. This java object is a java bean ( getter and setter methods on it).
( need jsp code)
Can I do like this:
<% ArrayList objList = (ArrayList)request.getattribute("lookupdata"): %> in jsp
(***I have done request.setattribute("lookupdata", arraylistobj); in action class. ***)
Assuming the java object has two properties, can I do the following
<% for (iint i=0. i<objList.size;I++){ %>
<td> what should i do here to get the first property of the object </td>
<td> what should i do here to get the first property of the object </td>
<% }
%>
if this approach is not proper, how can I pass the list of objects and parse in jsp?
I am not sure what will be the name of the object. I can find out how many are there but i am not sure I can find out the name
thanks a lot

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.

How to send object arraylist from servlet to jsp and display using jstl

Hi All....
I have a simple application and problem with it.
Once user logged in to system the user will redirect to LoginServlet.java controller.
Then in LoginServlet I want to redirect user to another page called book_details.jsp.
this is my login servlet.
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 // TODO Auto-generated method stub
 PrintWriter out = response.getWriter();
 ArrayList<BankAccountDTO> account_list = new ArrayList();
 ResultSet resultSet = null;
 LowFairAirDB airDB = null;
 try{
 airDB = new LowFairAirDB();
 String query = "SELECT account_id, type, description, balance, credit_line, begin_balance, begin_balance_time_stamp FROM bank_account";
 airDB.sqlSelect(query);
 resultSet = airDB.getResultSet();
 while(resultSet.next()){
 account_list.add(new BankAccountDTO(resultSet.getInt(1),
 resultSet.getInt(4),
 resultSet.getInt(5),
 resultSet.getInt(6),
 resultSet.getString(2),
 resultSet.getString(3),
 resultSet.getString(7)));
 }catch(Exception ex){
 }finally{
 try{resultSet.close();}catch(Exception ex){}
 airDB.sqlClose();
 }I set bank account values to BankAccountDTO.java objects and add them to the arrayList.
Next I want to send this objects arrayList to books_details.jsp and wanna display each objects values using JSTL.
I still finding a way to go through this.
1. Can anyone say how can I do it?
2. Is there any other method to do the same thing without using JSTL?
thanks in advance,
Dil.

In your servlet,

Good. I would only follow the Java naming conventions. E.g. accountList or accounts instead of the ugly PHP/C conventions.
In the JSP,
lst = (List< BankAccountDTO >)request.setAttribute("account_list");
for(BankAccountDTO b: lst){
populate your HTML tags or whatever
Wrong. 1) You need getAttribute() and 2) you should not use scriptlets. Use JSTL c:forEach, e.g.<table>
 <c:forEach items="${accounts}" var="account">
 <tr>
 <td>${account.id}</td>
 <td>${account.type}</td>
 <td>${account.description}</td>
 </tr>
 </c:forEach>
</table>To the topicstarter: for future JSP/JSTL related questions please use JSP/JSTL forum.

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.

Servlet passing values to JSP and ClasscastException

I am using weblogic 5.1 to run my Servlets.
          I want to know when I forward from a servlet to a JSP how do I pass
          values especially Java Objects (Sometimes Objects of User written Java
          classes).
          Uptil now I have been putting all values in the session from where the
          JSP picks them up, but somehow I have a feeling that this is not the
          right way.
          In a code I am putting a Java Object (It contains two attributes of
          Java.util.Vector type) in the session so that the JSP to which I am
          forwarding it to can use it I have put my class in the ServletClasses.
          Intertestingly it runs well till the contents of the Vector are changed.
          As the contents of the vector are changed, it throws ClassCastException
          The StackTrace is as follows:
          java.lang.ClassCastException

Only can confirm your finding - the jsp is using a different class loader to the servlet that originally instantiated the object. There's the rub. I haven't figured out yet how to fix that. I can get the classloader but don't know how to get the runtime to use that class loader to perform cast.

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?

ALV - need to sum values of internal table and display in ALV

I have data in internal table as:
Material date sum1 sum2
Mat_A 19990101 4 4
Mat_A 20080501 3 0
Mat_A 20080601 2 0
Mat_B 19990101 2 0
Mat_B 20080601 5 5
Required output is :
Material qty1 qty2 19990101 20080501 20080601
Mat_A 432 4 4 3 2
Mat_B 2+5 5 2 5
Thinking of using ALV to pass the internal table and display as classical report (and also to save as excel spreadsheet).
Counting your help on the following questions:
1) How to accomplish the sum in ALV report? Can ALV FM do that or one has to use ABAP to compute the sum from the given internal table?
2) Mat_A can have more date values. Here it got 3 distinct date values 19990101, 20080601, 20080501. If it has say 5 date values, how to create the ALV date columns (from 3 to 5 date columns) dynamically?

How to communicate between Flex and JSP and show the result in an Iframe

Hi all
I am trying to send some data from flex to one HTTPService and trying to show the same response jsp in an Iframe. But unfortunately i am unable to get the responce Jsp's url to set as a source for iframe.
let me explain you clearly...I have a mxml where i am having a text box and a button in the left panel and in the right panel i am having an Iframe to display jsp. So once user enters some value in the text box and clicks button then HTTPservice's send method will be called with text box's content as an arguement. So i can fetch that value from request object in jsp and display the value in jsp. So the problem here is i want display that result jsp in my Iframe. I know that , we need that result jsp URL to display in Iframe . But as i am sending POST request to HTTPservice, i am not able to get the result jsp's URL in flex side.
So i need help desperately from great minds.So anyone of you can give me some suggestions!!!!
Regards

Hi all can some one please give a solution ...Any suggestions would be greatly appreciated

Timeperiod between onClickButton and Display

Hi,
I was programming an iView which did quite a lot of data acquisition in the backend. When the data collection was fast I did not have any problems displaying the results.
As soon as the data collection took longer (more than two minutes) I had problems displaying the results in the portal. Not only was the result a blank screen, but also the portal was not running anymore due to JavaScript errors.
To trace the error I programmed a small "JSPDynPage"-iView with only one button which did (almost) nothing but cycle through several for-loops [see code below]. The result was still the same: blank page.
So does anybody know how I can accomplish this task? Is there a way to return to the JSP and display some temporary results and then when my data collection is done display the rest?
Thanks for any help,
Holger.

I tried returning ResultSet from bean but i get nothing display in my web page
instead it goes to error page (ErrorPage.jsp) which i handle in the jsp.
I tried many things but nothing work out please help me to attain a perfect

values but i got NullPointerException . But the values which i passed or
available in the database.
I dint get any reply for my last post please reply atleast to this.
i get the date in the jsp page is by this way
int Year=Integer.parseInt(request.getParameter("year"));
int Month=Integer.parseInt(request.getParameter("month"));
int Day=Integer.parseInt(request.getParameter("day"));
String startdate=Day+"/"+Month+"/"+Year;
int Year1=Integer.parseInt(request.getParameter("year1"));
int Month1=Integer.parseInt(request.getParameter("month1"));
int Day1=Integer.parseInt(request.getParameter("day1"));
String enddate=Day1+"/"+Month1+"/"+Year1;But this to check my bean whether it return any result!
public void databaseConnection(String MTName,String startDate,String endDate)
try
 java.text.SimpleDateFormat dateFormat=new java.text.SimpleDateFormat("dd/MM/yyyy");
 java.util.Date fromDate=dateFormat.parse(startDate);
 java.util.Date tillDate=dateFormat.parse(endDate);
 java.sql.Date sqlFromDate=new java.sql.Date(fromDate.getTime());
 java.sql.Date sqlTillDate=new java.sql.Date(tillDate.getTime());
 String query1="select MTName,Date,MTLineCount from Main where MTName='"+MTName+"' and Date between '"+sqlFromDate+"' and '"+sqlTillDate+"' " ;
 System.out.println(query1);
 Class.forName(driver);
 DriverManager.getConnection(url);
 preparedStatement=connection.prepareStatement(query1);
 preparedStatement.setString(1,"MTName");
 preparedStatement.setDate(2,sqlFromDate);
 preparedStatement.setDate(3,sqlTillDate);
 resultSet=preparedStatement.executeQuery();
 while(resultSet.next())
 System.out.println(resultSet.getString(1));
 System.out.println(resultSet.getDate(2));
 System.out.println(resultSet.getInt(3));
 catch (Exception e)
 e.printStackTrace();
I Passed value from my main method is like thisl

Pass arraylist from one JSP to another

Hi all,
I have a jsp in which i have a table with a list a of users. When we select some users and click on the deactivate link all these user information must be passed to another jsp which is a confirmation page to delete the users.
In my first userlist jsp i have the code
<h:commandLink styleClass="bold" value="Deactivate User" action="delete" actionListener="#{userlistcontroller.deleteaction}" ></h:commandLink>faces-config.xml
 <navigation-rule>
 <from-view-id>/userlist.jsp</from-view-id>
 <navigation-case>
 <from-outcome>delete</from-outcome>
 <to-view-id>/deactivateusers.jsp</to-view-id>
 </navigation-case>
</navigation-rule>In my backing bean action method i populate the list of users that need to be deacivated in an array list
 String userAction;
 List<Integer> selectedUserIDList;
 public void deleteaction(ActionEvent event){
 userAction = "delete";
 selectedUserIDList = new ArrayList<Integer>();
 for (CompanyAdminUser user : userList) {
 try {
 boolean val = selectedIds.get(user.getID()).booleanValue();
 if(val){
 selectedUserIDList.add(user.getID());
 } catch (Exception e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
}can someone help me how to pass this selectedUserIDList (arraylist ) and the userAction="Delete" to deacviate users jsp.
Thank you

You can easily pass the 2 variables you mentioned using <f:param> inside your <h:commandLink>.
<h:commandLink styleClass="bold" value="Deactivate User" action="delete" actionListener="#{userlistcontroller.deleteaction}" >
<f:param name="userAction" value="delete" />
<f:param name="userIDList" value="#{userlistcontroller.selectedUserIDList}" />
</h:commandLink>

Passing vectors into JSP from Servlet and passing data back to Servlet

I have been building an MVC application.
It has a controller which instantiates classes and evokes methods to
populate vectors. These vectors are then passed into a JSP. This part of the application works fine.
What I am having trouble with is a new JSP I have designed; this will
display the data that is actioned by the FORM action. This is actioned
based on the Search criteria entered by the user. Based on this a further vector is populated and brought back to the JSP as a vector
and this is rendered via the TABLE tag. Again this works fine.
Against each of the rows displayed, I have a print checkbox which can be checked by the user. On checking the records they want to print, they should then hint a Print button which should go back to the Servlet and print the data. THIS IS WHERE I HAVE THE PROBLEM. On going
back to the servlet the checkbox values are not displayed, rather
the values that initially populate the JSP. How do I get these new values back into the vector and hence accessible from the Servlet.
Any help with be very much appreciated.
Chris

Thanks for this.
Just to clarify I am not using Struts.
What I am having difficulties with is the fact that:
I can't get the checked values back to the Servlet - they keep the values they have in the bean - so as part of instantiating the bean class I set the value of the item to 'off'. The user will then check
the checkbox which should presumbably set the value to 'on'. This isn't happening because the setter method of the bean is not evoked again
because I don't come into this JSP again - the Servlet has finished here
and now needs to print the records. It can't do this because as
far as it is concerned nothing has changed since it last passed through
the vector to the JSP.
Even when I do the following:
Enumeration paramNames = request.getParameterNames();
String param = null;
while (paramNames.hasMoreElements())
param=(String)paramNames.nextElement();
System.out.println("parameter " + param + " is " +
request.getParameter(param));
what comes back is the valus of 'off' as opposed to 'on'.
The other thing is that 'request.getParameterNames()' only works
with the first record in the vector, i.e. it doesn't fetch any other
records that are rendered in the <TABLE> tag.
In desperation is there anybody out there who can help me.
Thanks
Chris
I am going to assume you are using a MVC framework
like Struts or very similar (I am assuming that from
the language you are using).
When the servlet passes the vector back to the JSP
page and you render the HTML that is passed back the
client your Vector is gone. The Vector is not
available at the HTML level that is being viewed at
the browser.
When the user selects the checkboxes and submits the
page (by clicking the print button) the controller
servlet (called ActionServlet in Struts, yours maybe
called something else) forwards the request to the
appropriate JavaBean and Servlet to process the
request. Either the JavaBean has to recreate the
Vector (not recommended) or the processing Servlet can
(better). You can do this by recreating the Vector
from scratch for the HttpRequest parameters or, at the
time of the initial request, saving Vector to a
session and then updating with the data you get back
from the client (again from the HttpRequest
parameters).
Either way you have to work with
HttpRequest.getParameter().

How to get the query values from the url in a servlet and pass them to jsp

ok..this is the situation...
all applications are routed through a login page...
so if we have a url like www.abc.com/appA/login?param1=A&param2=B , the query string must be passed onto a servlet(which is invoked before the login page is displayed)..the servlet must process the query string and then should pass all those values(as hidden values) to the login jsp..then user enters username and pswd, then there should be another servlet which takes all the hidden values of jsp and also username and pswd, authenticates the user and sends the control back to that particular application along with the hidden values...
so i need help on how to parse the query string from the original url in the servlet, pass it out to jsp, and then pass it back to the servlet and back to the original application...damnn...any help would be greatly appreciated...thanks

ok..this is the situation...Sounds like you have a bad design on your hands.
You're going to send passwords in a GET request as clear text? Nice security there.
Why not start with basic security and work your way up?
