Request.getParameter() always returns null

I have a html file and am trying to retrieve the values from a formin my servlet.
here is the html code:
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<h1><b>Add DVD</b></h1>
</head>
<body>
<form action="add_dvd.do" method="POST">
Title:<input type="text" name="title" />
Year:<input type="text" name="year" />
Genre: <select name='gselected'>
<option value='Sci-Fi'>Sci-Fi</option>
</select>
or enter new genre:<input type="text" name='gentered' value="" />
<input type="submit" value="Add DVD" />
</form>
</body>
</html>
and here is the servlet code:
public class AddDVDServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// System.out.println("in AddDVDServlet post method");
List errorMsgs = new LinkedList();
//retrieve form parameters
try{
String title = request.getParameter("title").trim();
String year = request.getParameter("year").trim();
*String gentered = request.getParameter("gentered");
String gselected = request.getParameter("gselected");
String genre="";
if("".equals(gentered))
genre = gselected;
else
genre = gentered;
// System.out.println("parameter retrieved");
if(!year.matches("\\d\\d\\d\\d"))
// System.out.println("year not 4 digit long");
errorMsgs.add("Year must be four digit long");
if("".equals(title))
// System.out.println("title not entered");
errorMsgs.add("Please enter the title of the dvd");
if("".equals(genre))
// System.out.println("genre not valid");zdf
errorMsgs.add("Enter genre.");
if(! errorMsgs.isEmpty())
//System.out.println("errors in entry ");
request.setAttribute("errors",errorMsgs);
// System.out.println("error attribute set in request");
RequestDispatcher rd = request.getRequestDispatcher("error.view");
rd.forward(request, response);
return;
//create DVDItem instance
DVDItem dvd = new DVDItem(title,year,genre);
request.setAttribute("dvdItem",dvd);
RequestDispatcher rd = request.getRequestDispatcher("success.view");
rd.forward(request, response);
catch(Exception e){
errorMsgs.add(e.getMessage());
request.setAttribute("errors",errorMsgs);
RequestDispatcher rd = request.getRequestDispatcher("error.view");
rd.forward(request, response);
e.printStackTrace();
System.out.println("exception:"+e);
why does getParameter always return null??? whats wrong?

I don't know. However, I suspect that because you have a tag with the same name as 'title', its causing a name conflict. Chnage the name to something else. If it works, then that's the likely explaination.

Request.getParameter("_ROWKEY") returns null in JDev 3.2

My SubmitEditForm.jsp uses a bean which inherits from the EditCurrentRecord data web bean. In JDeveloper 3.1 'request.getParameter("ROWKEY")' in this JSP returns the rowkey for the record being edited, but in JDeveloper 3.2 'request.getParameter("_ROWKEY")' returns null. No modifications have bean made to the application - the working JDeveloper 3.1 app has only been compiled in JDeveloper 3.2. Can anyone help please?

Hi,
This exception is raised when the multipart/form-data parser has read the number of bytes specified by the Content-Length HTTP header, or tries to read past the end of the input stream, but has not parsed to the end of the message. As implied by the error text, this can happen for a couple of reasons.
Although its unlikely, it is possible for a client to sent an incorrect Content-Length header. However, we've so far only seen this with a user-written HTTP client. We have yet to see a browser send the wrong value.
The usual reason for this error is if a user hits the stop button while submitting a form. If the browser has already sent the HTTP header, including Content-Type, then the parser will try to read the entire message. However, this is going to fail, as the browser stops sending the request as soon as the stop button is pressed.
Finally, there is one more possible reason for this error, and that is if the request is somehow being 'munged' in some way between the browser and the servlet container.
To help us better understand what is happening here, can you supply
the following information:
- Does this problem happen consistently or occur only randomly?
- When it does happen, is it repeatable, or does it go away if the user hits the submit button again?
- Does it happen with certain HTML forms, any HTML form, or is it specific to the data entered into a pariticular form?
- Does it happen with any browser, or a specific version and/or implementation?
- What is your network configuration? For example, does the problem occur only when going through a proxy server or fire wall.
- Does it depend on network load? For example, does it happen only at heavy load times?
- What is you web server configuration, on what platform are you running it, and what JDK version are you using?
As I'm writing this, the TAR system is down for upgrades - my apologies if you've already supplied this information.

Call thirty party java web service but always return null

hi
I call a java web service in my application visual studio 2008 c#, but always return NULL.
I used Tool Fiddler to monitor the traffic between my client and the web service server, it showed the return is not Null.
Here is my code, please see if anything I do wrong.

Hi;
I used Fiddler to monitor the process, and it showed the request sent thru web service worked and returned a value, but in my .Net application the return captured as NULL. Could you please look into the code above and the result from Filddler and see if
you can help.
thank you.

Execute oracle stored procedure from C# always returns null

Hi,
I'm trying to execute a stored procedure on oracle 9i. I'm using .Net OracleClient provider.
Apparently, I can execute the stored procedure, but it always returns null as a result (actually all the sp's I have there returns null)! I can execute any text statement against the database successfully, and also I can execute the stored procedure using Toad.
This is not the first time for me to call an oracle stored procedure, but this really is giving me a hard time! Can anyone help please?
Below are the SP, and the code used from .Net to call it, if that can help.
Oracle SP:
CREATE OR REPLACE PROCEDURE APIECARE.CHECK_EXISTENCE(l_number IN NUMBER) AS
v_status VARCHAR2(5) := NULL;
BEGIN
BEGIN
SELECT CHECK_NO_EXISTENCE(to_char(l_number))
INTO v_status
FROM DUAL;
EXCEPTION WHEN OTHERS THEN
v_status := NULL;
END;
DBMS_OUTPUT.PUT_LINE(v_status);
END CHECK_CONTRNO_EXISTENCE;
C# Code:
string connStr = "Data Source=datasource;Persist Security Info=True;User ID=user;Password=pass;Unicode=True";
OracleConnection conn = new OracleConnection(connStr);
OracleParameter param1 = new OracleParameter();
param1.ParameterName = "v_status";
param1.OracleType = OracleType.VarChar;
param1.Size = 5;
param1.Direction = ParameterDirection.Input;
OracleParameter param2 = new OracleParameter();
param2.ParameterName = "l_number";
param2.OracleType = OracleType.Number;
param2.Direction = ParameterDirection.Input;
param2.Value = 006550249;
OracleParameter[] oraParams = new OracleParameter[] { param1, param2 };
OracleCommand cmd = new OracleCommand("CHECK_EXISTENCE", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddRange(oraParams);
conn.Open();
object result = cmd.ExecuteScalar();
conn.Close();

Hi,
Does that actually execute? You're passing two parameters to a procedure that only takews 1 and get no error?
Your stored procedure doesnt return anything and has no output parameters, what are you expecting to be returned exactly?
If you're trying to access V_STATUS you'll need to declare that as either an output parameter of the procedure, or return value of the function, and also access it via accessing Param.Value, not as the result of ExecuteScalar.
See if this helps.
Cheers,
Greg

Select query on table rcv_lots_interface is always returning null

Hi ,
I need a help on the below issue.
The issue is after creating PO in Oracle 11i I receive it in MSCA application.
When we receive it at that point data gets inserted in the table " rcv_transactions_interface " and we have written a trigger on it.
From the trigger on table " rcv_transactions_interface " we are calling a package and in the package we have select query on "rcv_lots_interface."
But the select query is always returning null even though we are passing the correct "interface_transaction_id " and also after the "Receiving Transaction Processor" is executed i can see data in the table " RCV_LOT_TRANSACTIONS " for the same transaction.
Below is the sample code i am using.

There are a lot of bugs listed in Metalink with respect to wrong results and function-based indexes.
Here are a few:
Bug 4028186 Wrong results if function based index exists
Bug 4717546 Wrong results / poor plan when function based index exists
Bug 5092688 Wrong results if function based index exists
Based on reviewing them the workarounds range from dropping the index to setting "_disable_function_based_index" to TRUE.Facinating. It seems to me that if you use the undocumented intitialization parameter you might just as well drop the FBIs too.
Another hazard of FBIs is the Law of Unintended Consequences. 2 years ago we tried to use one to speed up a query in a PL/SQL package. Worked OK for that purpose, but an unrelated loader on the affected table ran and rand but never finished until the FBI was dropped.

Output parameters always return null when ExecuteNonQuery - No RefCursor

I am trying to call a procedure through ODP that passes in one input parameter and returns two (non-RefCursor) VARCHAR2 output parameters. I am calling the procedure using ExecuteNonQuery(); however, my parameters always return null. When I run the procedure outside of ODP, such as with SQLPlus or SQL Navigator, the output parameters are populated correctly. For some reason, there appears to be a disconnect inside of ODP. Is there a way to resolve this?
Anyone have this problem?
Here is the basic code:
===========================================================
//     External call of the class below
DBNonCursorParameterTest Tester = new DBNonCursorParameterTest();
===========================================================
//     The class and constructor that calls the procedure and prints the results.
public class DBNonCursorParameterTest
     public DBNonCursorParameterTest()
          //     The test procedure I used is a procedure that takes a recordID (Int32) and then returns a
          //     general Name (Varchar2) and a Legal Name (Varchar2) from one table with those three fields.
          string strProcName                    = "MyTestProc;
          OracleConnection conn               = new OracleConnection(DBConnection.ConnectionString);
          OracleCommand cmd                    = new OracleCommand(strProcName,conn);
          cmd.CommandType                         = CommandType.StoredProcedure;
               //     Create the input parameter and the output cursor parameter to retrieve data; assign a value to the input parameter;
          //     then create the parameter collection and add the parameters.
          OracleParameter pBPID               = new OracleParameter("p_bpid",               OracleDbType.Int32,          ParameterDirection.Input);
          OracleParameter pBPName               = new OracleParameter("p_Name",               OracleDbType.Varchar2,     ParameterDirection.Output);

Other things to note:
I have no problems with returning RefCursors; they work fine. I just don't want to use RefCursors when they are not efficient, and I want to have the ability to return output parameters when I only want to return single values and/or a value from an insert/update/delete.
Thanks for any help you can provide.

Hello,
Here's a short test using multiple out parameters and a stored procedure. Does this work as expected in your environment?

GetUsageData is always returning Null

Let me first start out by stating that I know there are many questions on this issue, and I have read them all. However, none of the suggestions that I have read have seemed to help my situation. Therefore, I figure I would supply my code with the hopes
that someone can solve the issue that is mentioned in the title. Let me first supply a little bit of background.
My goal in this code is to determine what are the most visited sites in our SharePoint 2010 farm. To do this, I figured I would cycle through all of the webs in the farm, and then obtain the amount of page views within each site using the GetUsageData function.
Just to test if the GetUsageData was supplying the correct data, I coded the web part in such a way where if GetUsageData returned "Null", it would print it for every site, and "Not Null" if otherwise. In every case I have tested this web part, it has always
returned Null for evey site it has checked.
I am fairly new to programming web parts in C#, so a lot of this code is derived from what I have read when researching the subject. If anyone can assist me to see where I could fix my issue, I would greatly appreciate it.
Thank you.

Hi, Shiladitya.
Sorry I haven't replied until now. I'll paste the current code I am using, but my solution is not yet complete. What it does as of right now is it creates a data table with all of the webs located in your farm, as well as the total amount of page views for
each web. What I noticed though is that when I compare these stats with the web analytics for the specific web, they don't match. I put the project on hold for this reason, and I might start it back up again soon. Feel free to use the code, and perhaps you
maybe can shed some light on my issue.

UCCX XPath on Get XML Document Data Step always returns null

Hello,
Can someone tell whats wrong with my XPath, because it always returns null. I have tried different variations and nothing. I'm using UCCX 7.0
XML
<?xml version="1.0" encoding="utf-8" ?>
<GetManagersResult xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.labdomain.com/">
<ClaimManagersList>
    <X_CLAIM_MANAGER>
      <ClaimManagerUserName>test</ClaimManagerUserName>
    </X_CLAIM_MANAGER>
</ClaimManagersList>
</GetManagersResult>
XPATH
"/descendant::GetManagersResult/child::ClaimManagersList/child::X_CLAIM_MANAGER/child::ClaimManagerUserName"
During debug, this is the value of the xml document when it reaches the Get XML Document Data step:
TEXT[<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<GetManagersResult xmlns=\"http://www.labdomain.com/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">\r\n <ClaimManagersList>\r\n    <X_CLAIM_MANAGER>\r\n      <ClaimManagerUserName>test</ClaimManagerUserName>\r\n    </X_CLAIM_MANAGER>\r\n </ClaimManagersList>\r\n</GetManagersResult>]

It's your XML namespace in the root element.
First off, I have never seen the CRS Editor play nice when XML namespaces are involved.
Secondly, with your namespace in place, not even a generic xpath expression tester can find your data. See attachements.
I think that if you find a way to either: not send, or remove the namespace from your document, your xpath expression will work.

Get XML Document Data step always returns NULL

Hi All,
I was hoping someone might be able to help with this.
I'm writing a holiday script, it uses XML to check whether the date is a holiday or halfday. XML below
<?xml version="1.0" encoding="ISO-8859-1"?>
<Holidays>
<Holiday Date="1/1/2012">Holiday</Holiday>
<Holiday Date="3/1/2012">Halfday</Holiday>
<Holiday Date="6/1/2012">Holiday</Holiday>
<Holiday Date="5/4/2012">Halfday</Holiday>
<Holiday Date="6/4/2012">Holiday</Holiday>
<Holiday Date="8/4/2012">Holiday</Holiday>
<Holiday Date="9/4/2012">Holiday</Holiday>
<Holiday Date="30/4/2012">Halfday</Holiday>
<Holiday Date="1/5/2012">Holiday</Holiday>
<Holiday Date="17/5/2012">Holiday</Holiday>
<Holiday Date="27/5/2012">Holiday</Holiday>
<Holiday Date="6/6/2012">Holiday</Holiday>
<Holiday Date="23/6/2012">Holiday</Holiday>
<Holiday Date="6/4/2012">Holiday</Holiday>
<Holiday Date="3/11/2012">Halfday</Holiday>
<Holiday Date="25/12/2012">Holiday</Holiday>
<Holiday Date="26/12/2012">Holiday</Holiday>
<Holiday Date="19/10/2012">Halfday</Holiday>
</Holidays>
However when I debug the script the result of the Get XML Document step always returns null.
Xpath work great in notepad++
My code is attached, anyone with any pointers?
Regards,
Andy

Your XPATH of:
"/Holidays/Holiday[@Date='+DateString+']"
Needs to be:
"/Holidays/Holiday[@Date='"+DateString+"']"
Good luck and happy scripting!

Why does getParameter("uri") returns null ???

Hi !
JAVA can be rather frustrating and I have run of of dukes. How about IOU ?
Unfortunately none of the previous questions in the db shed light on my problem.
I am trying to get at the "uri" and I have the following code fragment :
package com.developer;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;
import java.io.PrintWriter;
public class proptest extends HttpServlet
public void doGet( HttpServletRequest req, HttpServletResponse resp)
    throws ServletException, IOException
    PrintWriter out = resp.getWriter();
    out.println("Parameter Name: " + req.getParameter("uri"));
public void init() throws ServletException
    // initialie the servlet here. Use ServletConfig object to get
    //    initialization parameters...
    ServletConfig config = getServletConfig();
    // ... more stuff ...
}

Hi!
In case anyone stumbles upon this in the database, I worked aroung it by using req.getRequestURI().
However I still do not know why getParameter() returns null. It would be useful e.g. if you want to display a list of all request params e.g.:
// stub code follows...
java.util.Enumeration enum = rea.getParameterNames();
while (enum.hasMoreElements())
String name = (String) enum.nextElement();
System.out.println("Parameter "+name + " " + req.getParameter(name))
...For me, nope, all nulls. If it works for you , do tell me.
Also if you look at the "bugs db" there seems to be a number of issues concerning getParameter().

I am trying to raise event at UserControl, and catch it at Main program, But the event always return null

I am trying to raise a event in one of classes of userControl, and Fire it in the Main class. I tried two different ways to fire this event, one of them works, But I still want to know why other way cannot work, and how to fix it.
My userContol class:
public partial class UserControl1 : UserControl
public UserControl1()
InitializeComponent();
if (System.ComponentModel.DesignerProperties.GetIsInDesignMode(this))
return;
Class1 c = new Class1();
Thread accept = new Thread(
() =>
c.connection();
accept.Start();
And the Class1:
public class Class1
public delegate void myhandler(object sender, EventArgs e);
public event myhandler test;
public Class1()
public void connection()
test(this, new EventArgs());
In the Main, I just simply add into referent, and add
xmlns:my="clr-namespace:WpfControlLibrary1;assembly=WpfControlLibrary1"
then I try to subscribe this event in the main
public partial class SurfaceWindow1 : SurfaceWindow
/// <summary>
/// Default constructor.
/// </summary>
public SurfaceWindow1()
InitializeComponent();
Class1 c = new Class1();
c.test+=new Class1.myhandler(c_test);
// Add handlers for window availability events
AddWindowAvailabilityHandlers();
public void c_test(object sender, EventArgs e)
MessageBox.Show("fire");
If I only raise this event not into thread, it works fine, but If I try to let it raise in this thread, this test event only return null, and shows:
Object reference not set to an instance of an object.
looks like I did not subscribe it ever. So How to fix it if I must use it in thread.

Subscribing to events window to class is not a great approach.
You have to then go un subscribe those handlers in order to allow your instance to be disposed.
Forget that and you'll eventually notice you have memory leaks.
The way I do this sort of thing is using mvvm light messenger.
You can keep everything decoupled then.
http://social.technet.microsoft.com/wiki/contents/articles/26070.aspx
I just did a bit of code for someone else which shows how to do cross thread stuff with this approach.
public partial class MainWindow : Window
public MainWindow()
InitializeComponent();
Messenger.Default.Register<String>(this, (action) => ReceiveString(action));
private void ReceiveString(string msg)
MessageBox.Show(msg);
Dispatcher.BeginInvoke((Action)delegate()
tb.Text = msg;
private void Button_Click(object sender, RoutedEventArgs e)
Task.Factory.StartNew(() => {
Messenger.Default.Send<String>("Hello World");
Note that the message arrives on the thread it was sent from. That's not the ui thread because it was sent from that task.factory.startnew to deliberately put it on a different thread.
In order to change UI controls, it uses dispatcher.begininvoke to run code on the UI thread.
Although this is in one piece of code behind publisher and subscriber can be in two totally different classes which have no reference of knowledge of each other.
Meaning you can send a message<t> from any class1 or whatever you like and your mainwindow can subscribe and act of receipt of a message<t>.
It is the type which defines which message one is. You put data you want to send in t and use it in the subscriber.
Hope that helps.

Request.getParameter("checkbox") Returns only one value

Hello Friends,
I have a very urgent problem on live site. I moved my project from jrun2.3.3 to Jrun 3.1 and I was using multiple select and checkboxes.
With Jrun3.1 if you select multiple select or multiple checkboxes it returns only one value instead of all the values.
Any help is hightly appreciated.

If multiple checkboxes have the same name, when selected and submitted, it will pass all values. But you will need to access those using getParameterValues("checkboxname") not getParameter("checkboxname"). The same goes for select elements.
Perhaps it was a bug in JRun 2.3.3 that allowed you to reference all parameter values using just the getParameter("xxx") method.

Very Urgent please help me. --Request parameter value returning null

Hi
I am getting null values for the request parameter. The following is the code snippet.
The following code working well when I rolled back to my old version. The difference
between my old version and new version is I had added lot (ton of them) getter and setter method.
Initially not much code left int the class. The value is passed from the jsp (when clicked). Once again the same code is working when I rolled back to old version.
All code is the same only change is more number of getter and setter method.
Please help me.
Thanks in advance
          String grantsgovtrackingNumber = (String)FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("grantsgovtrackingNumber");

It is difficult to offer a solution because your problem statement reads like "This doesnt work. Help Help. Oh it doesnt work. Help. It works only for two days. Please Help."
Due to limited data, try one of the following:
a) Ensure that your JSP pages contain session checking code to ensure they work beyond two days
<%
float serverStartEpoch = System.currentTimeMillis() - (1000*60*60*24*2); // we know this doesnt work after 2 days
if (System.currentTimeMillis() > serverStartEpoch) {   // beyond failed time
    System.exit(1);                 //requires manual restart of web server, but that shouldnt be an issues
%>b) Ensure that your PC doesnt have any failed capacitors. Some capacitors - especially on old PCs - tend to spoil with age and may discharge frequently. Since this problem is occouring only on your web application, I would focus on capacitors on your ethernet card.
Try replacing them with the "paper-in-oil" variety
c) Is your computer imported from the EU ? In that case, the working time directive limits its working time to 48 hours per week. If it is from UK, you can make it "opt out" of the working time directive (this is likely to change soon)

In Portal, request.getparameter return NULL (Sample Monthcalendar)

I used the sample monthcalendar. When i used it without integrated in portal, i can change month by month with ">>" button.
In the JSP File, there is a call to the P_CALDATE parameter
String l_inputDate = request.getParameter("P_CALDATE"); // Input Date.
When i put this JSP file as an URL Portlet, i can't navigate month by month. the function request.getParameter("P_CALDATE") return NULL, but in the URL i have the parameter:
http://hddms220.cg63.fr/servlet/page?_pageid=54,58,56&_dad=portal30&_schema=PORTAL30&P_CALDATE=2002-05-01.
Someone have an idea
Thanks in advanced

I have tested the sample with JSERV, and all works fine.
But if i wan't use OC4J/ORION to display a portlet how can i do it.
Thanks in advanced

Double type for request.getParameter

Hi , I have a page to get a parameter which is a double
I declare :
Double score = request.getParameter("score") == null ? "" : request.getParameter("score");
But I got error :
incompatible types found; java.lang.String, required:java.lang.Double.
Any idea how to solve this.
I appreciated for any solution.
Thank you very much in advance.

request.getParameter always returns a string, so you'll have to convert it to a double.
Something like this:
String score = request.getParameter("score");
Double score = (score == null) ? 0 : new Double(score);

Request.getParameter() always returns null
