Undefined variable error
I defined the two variables upper_limit and lower_limit in my bean but I get an undefined variable message when I try to use them in my jsp page. Can anyone see what the problem is?
JSP code:
I'm thinking of a number between <%=lower_limit%> and <%=upper_limit%>.<p>
error message:

I defined the two variables upper_limit and
lower_limit in my bean but I get an undefined variable
message when I try to use them in my jsp page. Can
anyone see what the problem is?If these are defined in your bean this doesn't mean that you can access them directly from your JSP page.
try the <jsp:getProperty name="beanName" property="lower_limit"/> and <jsp:getProperty name="beanName" property="upper_limit"/>

I believe that's what these error codes are suggesting, not that you haven't defined the variable in your Bean, but that you haven't gotten the variable from the Bean.

Error when inserting into table - Undefined Variable
DB = Oracle 10.2.0.1
WEBSERV = Apache 2.0.55
LANG = PHP5
I have created (or more accurately, copied) a php script to insert data into one of my database tables when I press submit. The code is as follows (my connect string works fine and its included in the dbutils.php file):
<?php

include "dbutils.php";
$query = "insert into users values (seq_user_usr_id.NEXTVAL, '$usr_name')";
$cursor = OCIParse ($db_conn, $query);
if ($cursor == false){
echo OCIError($cursor)."<BR>";
exit;
$result = OCIExecute ($cursor);
if ($result == false){
echo OCIError($cursor)."<BR>";

Where would I declare this variable? It is just a check to see if the submit button is pressed as far as I can see. Any help would be greatfully appreciated.

<?php

HELP.! complier says one error: "undefined variable: SCROLLBARS_NONE"
I was compling my source code for a label to display properties. I decided not to have scrollbars in my applet so i put SCROLLBARS_NONE in a line of code. When I complied the source code my complier said one error: "undefined variable: SCROLLBARS_NONE". This is the line of code with the error:
Double.toString(s.getArea()),3,15,SCROLLBARS_NONE);
-Can someone please tell me or show me how to define the variable: SCROLLBARS_NONE?-java.awt.TextArea has that scrollbar variables. so you would say TextArea.SCROLLBARS_NONE.

Undefined Variable (Incoming Argument Error)
Hello,
I've created an XSD (Name: XYZ) in my BPM project and then created an instance variable (Name: asset) of type XYZ. I then created incoming argument and outgoing argument of the same type. Now I get an error message as stated below.
Undefined variable 'assetArg'
Note: I don't get an error message if i do the same steps and create it based on BPM object. But if i use XSD, I get the below error message. Any idea why?
Thanks for your help.Here's just a suggestion. I'd completely agree with you if you reported it as a bug, but here's how you can get it working.
Convert the incoming XML into a String before it arrives in the Begin activity of the process. In the logic below, I assumed that you would be willing to do this and you passed in your String as an argument variable called "incomingXmlStringArg" in the Begin activity.
In the Begin activity, you mapped the String "incomingXmlStringArg" into a variable called incomingXmlString. If this is going to be a big thing, I'd strongly recommend that you make this instance variable's type "Separated".
The xyz variable shown in the logic below is the instance variable you were wishing all along you could plop the XML directly into. "xyz" is a BPM Object instance variable of the type of the heir you created from your XSD. I'd strongly recommend that you also make this a Separated instance variable if it's going to potentially be huge.
Put this logic in and Automatic activity that immediately follows your Begin activity.
xyz = Model.Xyz()
load xyz
using xmlText = incomingXmlStringDan -
All of a sudden getting Undefined variable: attvalue in Squirrelmail
I'm running squirrelmail 1.4.17, and it's been running fine for about 2 months now. This week all of a sudden, I'm getting the following error when trying to read e-mails:
Notice: Undefined variable: attvalue in /usr/share/squirrelmail/functions/mime.php on line 1407
The attvalue variable has to do with stripping out dangerous characters from e-mails. My concern is that my system has been compromised and that someone has disabled this value in order to hack into my server.
The only non standard plugin I've installed into Squirrelmail is a filter that enables me to have an out of office message, it also helps me to move junk mail automatically. It too has been running fine for about a month.
If anyone can offer any advice, I'd greatly appreciate it. Like I said, everything was fine until just a couple of days ago. No updates took place, everything else seems fine on the surface.
Thanks
MikeI did forget to mention one thing. At the same time this started happening, I also had a problem that I had experienced before upgrading to the latest Squirrelmail, and that is that in the sending mail processing, specifically in the file deliver.class.php (line 614), I was getting a Notice: Undefined variable: default_charset in /usr/share/squirrelmail/class/deliver/Deliver.class.php on line 614.
I brute force fixed this problem by hard coding the default_charset variable in that function. I know that's not an ideal solution, but it at least fixed the problem from the users point of view.
Again, this wasn't happening until just recently, and I can't figure out what on the server changed to trigger these problems. -
Dear All,
Another post with a classic "undefined <VARIABLE> in
FORM" error message I'm afraid. I don't think this is the usual
problem of scoping however or form not submitting the data.
Basically I've checked and triple checked the file with the
<cfform> tag in it and it definately contains the relevant
controls with the names correct. I've also put <cfdump
var="#Form#"><cfabort> tags at the top of each file to
ensure the information is getting through. Looking at the Form
structure I can see the variables that are being posted (all of
which have the values passed from the file with the form tag).
However, despite this, when I remove the <cfabort> tag to let
the website process then the error message returns. I can't think
of what else might be causing this. Any ideas?
The actual .cfm files are pretty long but the jist of them is
as follows:

I think that the above statement says it all. I
wish that I had a dollar for every time that I looked at a piece of
code and could swear that there was nothing in it that could be
causing "the problem".... yeah, right.
Even if it is long, you might consider posting it if, for no
other reason, another pair of eyes may be able to spot the
"obvious" problem that your eyes may be skipping over (and over and
over.....).
<edit> FYI, I once actually had a CF template that
would fail just because it was a certain size... period. It was a
few CF versions ago, but if I made the template larger, or smaller,
no problem, But I made no actual changes other than size to keep it
from failing... very strange, but heck, you never know sometimes

Formula node forbid to run VI when undefined variable is used
On all LabVIEW version, we can use Formula node to evaluate mathematical formulas.
We can define input and output variable freely and calculate using some variety of formula.
But when we use undefined variable as output, can execute VIs with no errors.
We think it is a problem because when programmer makes a typo, they cannot notice the mistake.
When undefined variable is used as output variable, LabVIEW should forbid to run VI.I think you are going to get the same (or similar) answers than to my suggestion(s) to make VI outputs potentially "required" and the same for some functions (built-in VIs):
http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Allow-required-outputs-in-VIs/idc-p/3157058
http://forums.ni.com/t5/LabVIEW-Idea-Exchange/quot-Function-terminal-not-connected-quot-detection-plus/idi-p/1858573
In general, I agree with you, there is a potential for problems. Not really for the reason you are mentioning, because a typo will break the VI (unless you have two output variables with very similar names - unlike in your example - such as y and y0). But it could make for some frustrating debugging session. -
I am new to PHP & MySQL and am having a little difficulty. I am using Dreamweaver CS5.5 for website building. I just recently completed a tutorial by David Powers titled "Setting up a PHP developement environment for Dreamweaver. I downloaded and installed the latest version of XAMPP and found that things have changed a little since he made the tutorial making some of the screen shots and directions obsolete, but I managed to make my way through it with success until I got to the end. Everything was working and I successfully made a connection to my database, but when I clicked on "Live View" in dreamweaver I got error messages instead of the expected list of information stored in the database. Those error messages:
Notice: Undefined variable: database_connTest in C:\xampp\htdocs\php_test\comments.php on line 34Notice: Undefined variable: connTest in C:\xampp\htdocs\php_test\comments.php on line 34
Warning: mysql_select_db() expects parameter 2 to be resource, null given in C:\xampp\htdocs\php_test\comments.php on line 34
Notice: Undefined variable: connTest in C:\xampp\htdocs\php_test\comments.php on line 36
Warning: mysql_query() expects parameter 2 to be resource, null given in C:\xampp\htdocs\php_test\comments.php on line 36
Any Idea what is causing this and how to repair it. I desire to continue learning more about building a dinamic website but feel I need to discover and correct my mistakes before I go on. Is it possible that the sample file was created in a PHP or MySQL language that isn't recognized by the newest version of the XAMPP software package?
Thanks so much for your help.Yea I'm just really confused because I tested the server by making the "Time" php page that David had in his tutorial and it worked great. But when I installed the sample files as he instructed I was able to open the comments PHP file in dreamweaver and view it in design view or code view, but when I try viewing it in Live view, or on a browser all I get is the error message I pasted to my first post.

I have a beta version of a task management system that uploads new tasks to a SQL database using post and an HTTP service request. The same PHP page being posted to writes back an XML file that I use to get all of the information in a datagrid. All of the forms upload the all of the task info smoothly and the datagrid updates on the fly. My problem arises with a delete button inside the datagrid that that sends the ID of the selected item to my delete tasks PHP page through a function. I keep getting an error 1065 (undefined variable) when I click the delete button nested in a column of the datagrid. The code for my button is as follows
<mx:DataGridColumn headerText="clear task" editable="true">
<mx:itemRenderer>
<mx:Component>
<mx:Button label="Delete" click="deleteInfo();" />
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
The function in my CDATA reads
function deleteInfo()
var number = dgtasks.selectedItem.number;
del_number = number;
deleteTask.send();
Alert.show(del_number);
I have tried writing a number of different functions inside deleteInfo () just to see if it would even be called and I still get that error 1065. If anyone could help me out I would really appreciate. Thanks!Here is my entire file. The only thing negated are the URL's for the service requests. Thanks again!

Undefined variable or class name
I am trying to call a java class to another class but gets the error: "Undefined variable or class name"
Both my java files are in the same directory and I am able to compile only one of the program. Wondering what am I missing?
The source code is:
ServletUtilities.java: (I am able to compile)
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletUtilities {
public static final String DOCTYPE =
"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
"Transitional//EN\">";
public static String headWithTitle(String title) {
return(DOCTYPE + "\n" +
"<HTML>\n" +
"<head><title>" + title + "</title></head>\n");
HelloWWW3.java (getting error when compile)
public class HelloWWW3 extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println(ServletUtilities.headWithTitle("Hello WWW") +
"<body>\n" +
"<h1>Hello WWW</h1>\n" +
"</body></html>");I tried and I got these errors:

Undefined variable or classname snpRef (when executing Java within a KM)
Hi there,
I'm looking into ODI, specifically customizing scripts using java functions and have hit a bit of a problem.
Does the following error ring any bells?
Attempt to resolve method: getobjectname() on undefined variable or class name: snpref
I find it quite weird and strange that it cannot find snpref?
The script is below - as you can see, I'm just having a play around
drop table <%=odiRef.getTable("L", "COLL_NAME", "A")%>
+<%String sTestString = odiRef.getFrom(); %>+
+<%sTestString = sTestString.toLowerCase();%>+
+<%out.print("/*"+sTestString+"*/");%>+
As you can see, I have no clue where snpref is being called from. It may be an internal translation of odiRef but I thought snpRef has been deprecated!? What's also weird is that without the last or penultimate line, everything works fine?
For example, this works:
drop table <%=odiRef.getTable("L", "COLL_NAME", "A")%>
+<%String sTestString = odiRef.getFrom(); %>+
+<%out.print("/*"+sTestString+"*/");%>+
it gives:
drop table ODI_TESTING."C$_0SmalldatetimeTable"
+/*Testing.dbo.SmalldatetimeTable as SMALLDATETIMETABLE*/+
Also this works:
drop table <%=odiRef.getTable("L", "COLL_NAME", "A")%>
+<%String sTestString = "TeSt"; %>+
+<%sTestString = sTestString.toLowerCase(); %>+
+<%out.print("/*"+sTestString+"*/");%>+
outputting (as totally expected):
drop table ODI_TESTING."C$_0SmalldatetimeTable"
+/*test*/+
What gives? I know this is a bit theoretical but I'd really love to know what's causing it to break so spectacularly? Could it be some sort of misconfiguration?
Here's the stack trace:

Edited by: 979675 on Jan 9, 2013 1:04 AMOkay here is the solution.
I tried 100s of ways but it didnt work. So the alternative is create one more step in your KM with jython technology. Below code will print it in lowercase.
sTestString= '<%=sTestString%>'
raise (sTestString.lower())
Note: Click on ignore error. So that the flow will move on.

PHP returning "undefined" variable to flash
Hello Everyone, I am working on a touch screen POS login interface that takes in a four digit user pin and searches a database. It uses Flash, PHP and MYSQL. I need PHP to return the user name and access level. The AS3 code below is what I have so far, but it doesn't work correctly.
"IntLogin" is the 4 digit pin that is sent to PHP when the user touches login on the GUI.
function onLoginClick(e:MouseEvent):void
keyLogin.gotoAndStop("KeyDn");
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("Login.php");
var variables:URLVariables = new URLVariables();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
request.method = URLRequestMethod.POST;
variables.login = intLogin;
request.data = variables;
trace(request.data = variables);
loader.addEventListener(Event.COMPLETE, onComplete);
loader.load(request);
function onComplete(event:Event):void{
var loader:URLLoader = URLLoader(event.target);
var variables:URLVariables = new URLVariables(loader.data);
txtUser.text = variables.username;
Next is the PHP code which works great in the browser when I implictly give $select a value, returning "username=Walker&access=1"
However, when I run the program from Flash it returns an undefined variable and the end of the PHP file.
<?php # Login.php
require_once ('mysqli_connect.php');
//Connect to the db
if (!empty($_POST['login'])){
$select = $_POST['login'];
$sql = "SELECT Last_Name AS name, Access_Level AS level FROM Users WHERE User_ID = '$select'";
$q = mysqli_query($dbc, $sql);
if($q){
$row = mysqli_fetch_array($q, MYSQLI_ASSOC);
$name = $row['name'];
$access = $row['level'];
echo "username=$name";
echo "&access=access";
?>
I have have tried debugging the both the PHP and the AS code, but I am stuck. When I trace in AS3 I get the following:
1445
login=1445
undefined
$access";
?>
Please if you anyone can help with this it would be greatly appreciated. I am on a strict timeline and I don't know what to do here.
Thanks:)
JusmarkYou have to send it as a flash var
Take a look at the code on my php webpage:
http://www.spectacularstuff.com/php-test/inprogress/scrfix/home.php
That is how I sent it to flash. Now, we want to receive it in
flash. You need the following actionscript in AS3.
// Display FlashVar onto webpage to ensure we are
// receiving it
var tf:TextField = new TextField();
tf.autoSize = TextFieldAutoSize.LEFT;
tf.border = false;
tf.x = 50;
tf.y = 10;
addChild(tf);
// Detect the FlashVar from the webpage
try {
var keyStr:String;
var valueStr:String;
var paramObj:Object =
LoaderInfo(this.root.loaderInfo).parameters;
for (keyStr in paramObj) {
valueStr = String(paramObj[keyStr]);
if (keyStr.indexOf(".") != -1){
keyStr = keyStr.substring(0, keyStr.indexOf(".")); //now
it's "home"
// tf.appendText(keyStr);
} catch (error:Error) {
// tf.appendText(error); -

You can refer to it in a JavaScript script, like this:

Getting a bad bind variable error while compiling a custom form in R12
Hi,
I am getting a bad bind variable error while compiling a custom form.
I tried setting the forms_path variable and I am still getting the error. Can anyone please suggest what can be done?
DECLARE
BEGIN
IF :parameter.p_line_ship_to = 'T'
THEN
IF :SYSTEM.cursor_item = 'LINE.SHIP_TO'
THEN
:parameter.lov_num_param1 := :line.ship_to_customer_id;
oe_lines.ship_to ('WHEN-VALIDATE-ITEM');
:parameter.lov_num_param1 := :line.ship_to_customer_id;
END IF;
:parameter.p_line_ship_to := 'F';
END IF;
END;
I am getting this error:
Bad bind variable 'parameter.p_line_ship_to'The Parameter is not defined in the form.. But, this form is already been compiled and deployed.. I have to make some changes to the form and tried to compile it, when i am getting this error. Is it possible that the parameter would be defined in some other form or can this error be due to some other reasons?
Thanks in Advance. -
"undefined symbol" error while using a custom instrument driver
Hello all, I'm facing a problem related to instrument driver creation.
I want to pack a part of my code to a .FP to be able to reuse it in other applications of mine. This part of code includes calls to Windows API and a third party dll. I have included both windows.h and the include for the dll in the header file for the instrument. I developed the source code and next a little application that simply calls one function to test the result of my work, but I get some 'undefined symbol' errores while linking the test application with the instrument. The instrument header file is included in program source file.
Situation is as follows:
I can run the test application if I include the source file for the instrument directly in the project (without loading the instrument)
I created a static library and can have the test program up and running if directly including the library in the project (again without the .fp file)
I get linker errors when trying to use the instrument I created based on the same code, both when including the instrument at source code level and when including at library level. Adding the .fp to the project makes no difference
Linker errors are all related to WinSDK and third-party dll functions.
Question is: where and how I have to declare the symbols apart including the appropriate .h files in the instrument header file?
Proud to use LW/CVI from 3.1 on.
My contributions to the Developer Zone Community
If I have helped you, why not giving me a kudos?Being waited on to log on... how flattering
I wish I had a simple and obvious solution, but I don't.
The problem in this case is that, whereas DLLs (via their import libraries) carry no additional build-time dependencies to their clients, that is not the case with object files and static libraries: any project that uses those .obj and .lib files must satisfy all of their dependencies when that project builds.
There is a mechanism, with .fp files, to advertise such dependencies to the clients of the .fp, and that is the auto-load list (Edit>>FP Auto-Load List, in the function tree editor). The caveat, however, is that these indirect dependencies must have a companion .fp that you can add to this list. And in your case, you don't have one. So the only solution I can think of is for you to create a very thin wrapper module where you would wrap all of the SDK functions that you need, then create a basic .fp for this wrapper -- you can do this semi-automatically, from the header file (Options>>Generate Function Tree) -- and then add this .fp to the auto-load list of your primary .fp. And then you'll probably have to create a second .fp wrapper for your other dependency (a non-SDK third-party DLL?).
Once you have declared the dependency chain for this .fp, you should then be able to use it on any test application and CVI should know to link in these additional static libraries whenever it builds the test application.
If you choose to go this route, you'll probably have to deal with a bunch of non-standard data types in the parameters of the SDK functions. I don't remember if these are automatically added to the .fp when you create it from the header file. If not, all you need to do is add them to the .fp later (Options>>Data Types, from the function panel editor). Don't worry about providing the definitions for these data types. They're not necessary. You just need to make sure that their names are in the list.

Html5 animation only plays once???
I have an html5 animation that plays fine if I click or tap it the first time. If I change pages and return, the animation shows the correct "start" poster, but clicking it goes directly to the last frame, as if the animation remained at that frame,
