Closing jsp page

hi infocrats,
my problem statement:
i m using a page say A.jsp, which is home page, and it is posted to B.jsp, which is used for validation, and it may redirect to A.jsp if value entered does not meet the condition.
now at the time of redirection i get the error message:
IllegalStateException
on line of redirection
plzzzzzzzz help its urgent.

Whenever you forward/redirect make sure you return control at that point.
Otherwise it will continue execution of the page, and possibly send more data back to the page - which creates the IllegalStateException
ie something like this
if (pageHasError){
RequestDispatcher.forward("/errorPage");
// must return here, otherwise execution of this page would continue
return;
// continue as we are ok
// If the page had an error and we didn't return above, this
// line of code would create an error as we try to execute it when we have
// already forwarded to another resource to do the response.
RequestDispatcher.forward("successPage");

In JSP pages request.getParameter returns null

There are two jsp's,the first JSP has 1 textbox inside the form tag.We input the values in the textbox and submit.
Code :Ist jsp
<BODY>
<HEAD>
function validate()
document.add.submit();
</HEAD>
<FORM name="add" method="post" action=/dir/two.jsp" >
<TABLE width="37%" border="0" align="center" class="c4f3">
<TR>
<TD class="c4">Rating</TD>
<TD><input type=text name="rating"></TD?
</TR>
<TR>
<TD align=center><INPUT type="button" name="submitadd" value="Submit" onClick="validate()" </TD>
</TR>
</TABLE>
</FORM>
</BODY>
After the submit it goes to the 2nd JSP page .
code:2nd Jsp
<%
String Rating=request.getParameter("rating");
out.println(" Rating "+Rating);
%>
The 2nd JSP pages gets the values by request.getParameter.When I use method='post' in Ist JSP ,even if I enter values in the textbox, it prints null. But when I give method="get" , it prints the value.
Pls let me know if there is any problem in the code or its the problem due to webserver configuration.Also suggest the solution to over come this problem.
Thanks

If I'am right you have misplaced the opening body-tag of your first jsp-page.
The opening body-tag should follow after the closing head tag .
The structure of your HTML-code should look like this:
<html>
<head>
</head>
<body>
</body>
</html>

How to use one ResultSet many times in a jsp page ?

Hi all,
I have .jsp page and I have used it to get data from DB and display them to users. So I have to get data from DB in number of places in this particular jsp.
I thought that it is better to have one ResultSet for entire page and once it is done its job, the ResultSet will be closed and I can use it again and again like this.
Resultset rs = new ResultSet();
try{
    //My operations
}catch(Exception ex){
   //Handle Exceptions
}finally{
   rs.close();
}After above code snippet I can use same ResultSet again below the page.
I just want to know this,
1. is this a good coding practice?
2. Should i put rs = null; within finally clause?
any help will be appreciated
thank in advance,
Dilan.

Ok, Finally I switched my coding to use DAO and DTO, and I learned it through internet.
I removed all of data access codes from my jsp file(lets say 'functions.jsp'). I then created one interface and two clasess.
here is my DAO interface.
public interface UserFunctionsDAO{
    public List<UserFunctionsDTO> selectUserList();
}here is DTO class
public class UserFunctionsDTO{
    private String category = "";
    private String sub_category = "";
    private int cat_id = 0;
    private int sub_cat_id = 0;
    public UserFunctionsDTO(){}
    public UserFunctionsDTO(String category, String sub_category, int cat_id, int sub_cat_id){
        this.category = category;
        this.sub_category = sub_category;
        this.cat_id = cat_id;
        this.sub_cat_id = sub_cat_id;
    //Setters and getters will go here.
}my concrete data access class is like this.
public class UserFunctionsDataAccess implements UserFunctionsDAO{
    MyDB dbObject = null;
   private static final String SQL_GET_DISTINCT_CAT= "SELECT DISTINCT cat FROM cat_table";
   public List<UserFunctionsDTO> selectUserList(){
       dbObject = new MyDB();
       dbObject.sqlSelect(SQL_GET_DISTINCT_CAT);
       ResultSet rs = dbObject.getResultSet();
       ArrayList list = new ArrayList();
       while(rs.next()){
           list.add(new UserFunctionsDTO(rs.getString('category'), .......................));
       return list;
}I think now im following good coding practices, but I have one problem.
1. How do I retrieve this userlist from my jsp page?
2. Should I include UserFunctionsDTO in my jsp page as a bean?
3. If I include it, how can I get the list from it?
thanks in advance,
Dilan.

Error when deploy a jsp page which includes customizable component

Hi all,
I add a customizable component to my jsp page. It works fine on local but when I deploy it and run the deployment I get the error below:
500 Internal Server Error
OracleJSP:
JSP Error:

anyone who has an idea?
thanks a lot in advance

Did you define a web.xml and application.xml file for the deployment of your application?
Are you using deployment profiles to configure your application on a standalone OC4J?

Using JavaBeans in a JSP Page

I wan't to know the advantages and disadvantages of using JavaBeans in a JSP page.
Like for example general traditional approach for a database connection
is to create a connection and access the database from that and close the connection
at the end of the page, instead of the If I use a common connection bean for making connections,
is that suggestable and then when should i close the connection then.
One good application of JavaBeans is using a Set and Get methods for form fields in
a registration form to get back the values.
So may i know how best can we use the JavaBeans other than this application.
ThanX in advance,

I believe putting processing and query code in the JavaBean was one of the reasons for putting JavaBeans support in JSP in the first place. The original idea was to use the setXXX methods to populate the bean's data from the posted form, then do the processing (or database query), then use the getXXX methods to display the bean's data.
Efficiency-wise, it's exactly the same as putting all the code in-line in the JSP page (actually, it might be a bit slower, because of the reflection required to do it.) Code-wise though, it makes the JSP easier to read.
Of course, we have EJBs now too, which tie very closely and can match database queries almost one-to-one, one way to incorporate these is inside the JavaBean you reference from the JSP, another way from a servlet you redirect the JSP to, etc...

Uploading a photo in a jsp page

hi Friends,
i have 4 fields

when i click on 'Save ' , it shud save the link in database as well as show the uploaded photo in apge called 'Photos.jsp"
basically my query is how i upload photo thru jsp ?
thnx in advance

Here is the solution to your problem dear.
just set the attribute of form ENCTYPE="multipart/form-data" and call this servlet from your jsp page
//=============================This Servlet stores image
import myConPack.Connect; //my own class to connect to db
import java.sql.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
public class UploadIntoDB extends HttpServlet {
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException
     PrintWriter out=response.getWriter();
     String contentType = request.getContentType();
//IF FORM HAS PICTURE ALSO THEN IF CONDITION WILL EXECUTED FOR WRITING IMAGE INTO DB
     if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0))
     DataInputStream in = new DataInputStream(request.getInputStream());
     int formDataLength = request.getContentLength();
     byte dataBytes[] = new byte[formDataLength];
     int byteRead = 0;
     int totalBytesRead = 0;
     while (totalBytesRead < formDataLength)
     byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
     totalBytesRead += byteRead;
     String file = new String(dataBytes);
String saveFile = file.substring(file.indexOf("filename=\"") + 10);
          saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
     saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
     int lastIndex = contentType.lastIndexOf("=");
     String boundary = contentType.substring(lastIndex + 1,contentType.length());
     int pos;
          pos = file.indexOf("filename=\"");
          pos = file.indexOf("\n", pos) + 1;
          pos = file.indexOf("\n", pos) + 1;
          pos = file.indexOf("\n", pos) + 1;
     int boundaryLocation = file.indexOf(boundary, pos) - 4;
     int startPos = ((file.substring(0, pos)).getBytes()).length;
     int endPos = ((file.substring(0, boundaryLocation)).getBytes()).length;
     ByteArrayInputStream bais=new ByteArrayInputStream(dataBytes,startPos,(endPos-startPos));
     //========================================
     if((bais.available())>0)
     try{
          Connect connect=new Connect();
          Connection con=connect.getConnection();
          String SqlQuery="insert into tbl values(?,?)";          PreparedStatement pst=con.prepareStatement(SqlQuery);
          pst.setString(1,saveFile);//filename of image
          pst.setBinaryStream(2,bais,bais.available());//image itself
          int result=pst.executeUpdate();
          System.out.println(result+ "Row Added");
     }catch(Exception e) { System.out.println("Exception : "+e); }
     RequestDispatcher rd=request.getRequestDispatcher("/backto.jsp");
     if(rd!=null)
          rd.forward(request,response);
     else
out.println("NO IMAGE WAS Found ");
     }//if closed
}//function closed
}//class closed

Problem in Reloading JSP Page

I am having list of users in parent window(1st JSP Page), user selects one user and presses edit button, the details of the selected user is populated in the pop-up window (using java script), now user modifies the details and presses the save button and i am fwd to parent window(child window is closed), now the details are saving in the database but the parent page is not displaying the updated user details. i am using struts to pass data from jsp to db. Even i used System.out.println statement in the user display loop(parent jsp page), the updated details is printing, but it is not shown in the web page.
Sabarish R L

Hi,
This is because ur page is not refreshed.
After updating database when u coming back to ActionClass, you can invoke mapping which refreshed ur JSP (means call a mapping which invoke ur JSP again but remember do not hit the database again it will reduce programe efficiency).

Best Practive to resturn Resultset to a JSP page

I'm writing a class to return a resultSet to use in a JSP page or at least i think thats what i want to do. Whats the best practice to return that resultset.....As the class is written below, when i try to iterate through the resultset in the jsp page i get a NullPointerException which i understand because i closed the connection before returning....If i take out all the code in the finally section i can iterate through the data no problem....but thats not good to leave connections open.......instead of returning a resultset should i return some other type such as an Array with all the data. How should i return the data?

Yes, when you close your connection all data in your result set is lost, and yes its not a good idea to keep connections open. Its also not a good idea to pass results around. What you should do is store the data in some type of collection object and pass that to your jsp.
for exmaple if you select data from a table that stores names of people, e.g. two columns first_name and last_name, then create a class called People with two private string members to hold the first and last names. loop through your result set and build a People object for each row of data. when your done close the result set (and the connection if you want). store all your People objects is a collection (vector, array, whatever). pass the vector to your jsp for display.

Embeding audio player in jsp page.

Hello All,
I have embed the quickTime player in a jsp page. Following is my code snippet of the object embedding.
When I run the project my programme download and save the amr file from my database in the specified project location("../image/"+recordId +".amr"), but not run the amr file. Only logo of the player is displayed. Next Time when i run the project again, the amr file run smoothly. Probabely the problem is, when the programme run first time it could not find the required amr file location.
My requirement is, after click a button, it will download the amr file in specific location and then read the file from that path. The file download successfully before embedding the object, but do not run the file.
Also, the programme could not run the amr file from other than the project location. I am new in developing the jsp page, where amr file have to be play directly from the page. How can i solve the problem?
any idea, please help.
Code snippet:
<% String recordId = request.getParameter("pId");
String path=null;
path="../image/"+recordId +".amr";
%>
<object classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" width="50" height="50" standby="Data is loading..." codebase="http://www.apple.com/qtactivex/qtplugin.cab">

This makes no sense, you're only duplicating the bytes and adding unnecessary overhead. Either keep it entirely in the DB, or just keep it at the disk file system and have the file attributes only in DB.
but not run the amr file. Only logo of the player is displayed. Next Time when i run the project again, the amr file run smoothly. You apparently did not close the file outputstream after write.

Updating JSP page

Hi all,
I have a web application implemented using MVC architecture. In the application, statistics of "clients" are displayed on a table. The user can select some "clients" and clicks on a "Workbench" button. This will trigger a new window to another application (developed using echo 3 framework) through javascript window.open() whereby files uploaded by the "clients" selected is displayed. Some parameters of the clients can be changed in the 2nd application. When the user moves back onto using my application, how do i go about updating the changes done on the 2nd application over to my application? Both applications uses the same database.
Currently, this is handled through the 2nd application calling on my servlet using window.open(), which on my end, i will re-initialize the javabeans and forward back to my index page. However, this will cause an additional window to open everytime there is an update on the 2nd application, which is not elegant.
Sorry if this sounds confusing.

HI,
i suggest simply reloading your jsp page.
This can be accomplished by calling a java script function in the child window before closing:
<script>
opener.location.reload(true);
window.close();
</script>Regards,
Ape

Progress bar onLoad of jsp page.

Hello all,
I was wondering how to put a progress bar on load of jsp page.
Also I have html page that calls a servlet. It takes some time to run it.
So, is there a way to put a progress indicator while serlvet is doing work?
thanks

You can fix that in your page template by putting something like this just before the BODY tag in the Header region:
<div id="loading"
style="display: block;
         position: fixed;
         top: 0px;
         left: 0;
         z-index: 1999;
         width: 100%;
         height: 100%;
         background-color: #fff;
         text-align: center;">
<div style="position: relative;
            top: 130px;">
Wait..loading..
</div>
<img src="#IMAGE_PREFIX#themes/theme_200/images/loading.gif" height="32" width="32"
   style="position: relative;
          top: 150px;"/>
</div>and putting something like this just after the closing BODY tag in the Footer region:
<script>
$(document).ready(function(){
$('#loading').hide();
</script>

While refreshing jsp page through javascript

Hi,
I am refreshing a jsp page by calling javascript method -'reload()', when its child window is closed. It is displaying a confirmation box saying 'whether to resend the request for refreshing the page.....' with two buttons-ok and cancel.
How do I avoid this confirmation box ? I want to reload the jsp page without asking any confirmation msg.
Please help me out.
thanks

if you use meta refresh you will lose your data your best bet is to create an object relating to your page, basically a bean and store all your values into that bean, save it into the database then recall after refresh, but make sure you test that the object contains something before retrieving the values from it
