If statement is not validating properly in JSP

Actually i'm new to Java..
The problem is when i take the parameter from another file which is an empty text box and i submit that. In the next jsp file i'am taking this value using getParameter("xxxx").
if i send the empty or some value to this parameter, the if statement is not validating properly.
here is my code in jsp....
<%
String bgcolor = request.getParameter("bgColor");
out.println("Background Color = " + bgcolor);
if (bgcolor == null)
out.println("Hello Null");
else
out.println("Hello Not Null");
%>
Thanks in advance

Hey there, you should know that Strings in Java are
different from other types like int and double for
example. Strings are objects so you cant check em
with == but with the standard method .equals This is true but is not the problem here.
@OP null and an empty length string are NOT the same thing. You probably want a check like
if(bgColor.length()<1)And you might want to trim the String first to get rid of whitespace.

Statement is not valid in a namespace site

You need to learn the structure of a program. You can not just place code willy nilly anywhere and think that will work.
Also you need to know what code can go where also. That will take time too. The information below is from the second link below. But when you read it you need to realize the difference in methods used by a console application and most other project styles.
So if you are unaware of that you may end up not understanding why certain information is not necessary for a Windows Forms app while other information is not necessary for a console app.
For example the Main Procedure I see used in console apps. In Windows.Forms apps not so much except for possibly extremely old VB.Net code and mostly I would have to guess by people who used to write console apps all the time then tried Windows.Forms apps
and for whatever reason couldn't refrain from using console app procedures in Windows.Forms apps which is unecessary and in my opinion quite confusing.
TutorialsPoint - VB.Net - Program Structure
Structure of a Visual Basic Program
File-Level Programming Elements
When you start a project or file and open the code editor, you see some code already in place and in the correct order. Any code that you write should follow the following sequence:
Option
statements
Imports
statements
Namespace
statements and namespace-level elements
If you enter statements in a different order, compilation errors can result.
A program can also contain conditional compilation statements. You can intersperse these in the source file among the statements of the preceding sequence.
Option Statements
Option
statements establish ground rules for subsequent code, helping prevent syntax and logic errors. The
Option Explicit Statement (Visual Basic) ensures that all variables are declared and spelled correctly, which reduces debugging time. The
Option Strict Statement helps to minimize logic errors and data loss that can occur when you work between variables of different data types. The
Option Compare Statement specifies the way strings are compared to each other, based on either their
Binary or Text values.
Imports Statements
You can include an Imports Statement (.NET Namespace and Type) to import names defined outside your project. An
Imports statement allows your code to refer to classes and other types defined within the imported namespace, without having to qualify them. You can use as many
Imports statements as appropriate. For more information, see
References and the Imports Statement (Visual Basic).
Namespace Statements
Namespaces help you organize and classify your programming elements for ease of grouping and accessing. You use the
Namespace Statement to classify the following statements within a particular namespace. For more information, see
Namespaces in Visual Basic.
Conditional Compilation Statements
Conditional compilation statements can appear almost anywhere in your source file. They cause parts of your code to be included or excluded at compile time depending on certain conditions. You can also use them for debugging your application, because conditional
code runs in debugging mode only. For more information, see Conditional Compilation in Visual Basic.
Namespace-Level Programming Elements
Classes, structures, and modules contain all the code in your source file. They are
namespace-level elements, which can appear within a namespace or at the source file level. They hold the declarations of all other programming elements. Interfaces, which define element signatures but provide no implementation, also appear at module
level. For more information on the module-level elements, see the following:
Class Statement (Visual Basic)
Structure Statement
Module Statement
Interface Statement (Visual Basic)
Data elements at namespace level are enumerations and delegates.
Module-Level Programming Elements
Procedures, operators, properties, and events are the only programming elements that can hold executable code (statements that perform actions at run time). They are the
module-level elements of your program. For more information on the procedure-level elements, see the following:
Function Statement (Visual Basic)
Sub Statement (Visual Basic)
Declare Statement
Operator Statement
Property Statement
Event Statement
Data elements at module level are variables, constants, enumerations, and delegates.
Procedure-Level Programming Elements
Most of the contents of procedure-level elements are executable statements, which constitute the run-time code of your program. All executable code must be in some procedure (Function,
Sub, Operator, Get,
Set, AddHandler, RemoveHandler,
RaiseEvent). For more information, see Statements in Visual Basic.
Data elements at procedure level are limited to local variables and constants.
The Main Procedure
The Main procedure is the first code to run when your application has been loaded.
Main serves as the starting point and overall control for your application. There are four varieties of
Main:
Sub Main()
Sub Main(ByVal cmdArgs() As String)
Function Main() As Integer
Function Main(ByVal cmdArgs() As String) As Integer
The most common variety of this procedure is Sub Main(). For more information, see
Main Procedure in Visual Basic.

The SQL statement is not valid - when importing data from SQL Server using a query

Hi there,
I am trying to import data from SQL to Power Pivot using a SQL query like below:
SELECT Score.FieldCount, Score.Record.GetAt(0), Score.Record.GetAt(1), Score.Record.GetAt(2), Score.Record.GetAt(3), Score.Record.GetAt(4)
FROM
SELECT * FROM dbo.CLR1(
dbo.CLR2('c:\FILES\Test.xml'),
'SELECT * FROM [dbo].[CXCustomer_Small]') Input
) Score
And when I tried to validate it, it returns
The SQL statement is not valid. A column name cannot be blank.
I ran the above SQL statement in Management Studio and it works without problem. Any idea?
Thanks!

SQL command (with XPath) does not work properly with JSP

Hello everyone,
I try this SQL command on Oracle SQL Developer,
select filename,
extract(xml_col, '/Operation/Records/tabDetail/Vehicle_Level/text()') as Vehicle_Level,
extract(xml_col, '/Operation/Records/tabDetail/Vehicles_Closed/text()') as Vehicles_ID
from ope
where upload_datetime in
(select min(upload_datetime)
from ope
where (TO_DATE(TO_CHAR(upload_datetime, 'DD-MM-YYYY'),'DD-MM-YYYY'))
between TO_DATE('01-01-2008','DD-MM-YYYY') and TO_DATE('01-07-2008','DD-MM-YYYY')
HAVING (filename like '60-1-%')
GROUP BY filename);
It works properly, the result is :
FILENAME --------------------- VEHICLE_LEVEL --------------------- VEHICLES_ID
60-1-OPE-1.xml --------------------- 3 --------------------- 60-1-VEH-43
But when I try this command on JSP, the result is :
FILENAME --------------------- VEHICLE_LEVEL --------------------- VEHICLES_ID
60-1-OPE-1.xml --------------------- null --------------------- null
I don't want "null" value, but I don't know where is wrong. Please help me.
Thank you very much.

Hello experts read table statement is not working properly

Hello Experts.
my code is like this.
sort it_matnr by matnr.
loop at itab_result.
read table it_matnr with key matnr = itab_result-matnr binary search.
endloop.
there are nearly 2000 records in it_matnr . The records which satisfy the above condition is there here in this internal table. But it is unable to read the record which matches the condition. One thing is that , there are more than one record with the same material. ie mblnr is different but material is the same. In it_matnr table i have only 1 field ie matnr ,so i need to compare only with the matnr.I also tried by sorting it_result by matnr but of no use. Then finally I used loop at where matnr = it_result-matnr , it is working fine. But due to performance reasons we should not use this. so please tell me what to do and correct the code.

1. Make sure that the table IT_MATNR is not getting updated inside the loop. Because it will then destroy the sorting.
2. Secondly, if there are multiple records in IT_MATNR for the same material then it will search for the first record encountered in binary algo. So it is advisable that you may provide further filter criteria if possible. check if ITAB_RESULT & IT_MATNR have any other matching field that can be put in filter criteria.
3.Thirdly, check if your requirement can be achieved by STABLE SORT.
<b>SORT <itab> ... STABLE BY <f1>[ASCENDING/DESCENDING].</b>
It will allows you to perform a stable sort, that is, the relative sequence of lines that are unchanged by the sort is not changed. If you do not use the STABLE option, the sort sequence is not preserved. If you sort a table several times by the same key, the sequence of the table entries will change in each sort. However, a stable sort takes longer than an unstable sort.
4. Lastly, you can use parallel cursor technique of multiple loops which is given below:
LOOP AT itab_result.
READ TABLE it_matnr
    WITH KEY matnr = itab_result-matnr
    BINARY SEARCH.
Process record
LOOP AT it_matnr FROM sy-tabix.
    IF it_matnr <> itab_result-matnr.
      EXIT.
    ENDIF.
Process record based on yuor condition
ENDLOOP.
ENDLOOP.

Expressions not evaluating properly in jsp:plugin tag

Hi there, running OC4J as Oracle9iAS (1.0.2.2.1)
In the JSP1.1 spec dynamic expressions in the jsp:plugin <param> tag are clearly specified as below:
<jsp:params>
[ <jsp:param name="parameterName" value="{parameterValue | <%= expression %>}" /> ]+ </jsp:params>
Unfortunately, attempting this in OC4J, the expression is simply displayed as a static String, for example the following JSP source:
     <jsp:params>
          <jsp:param name="rootSubAssembly" value="<%=rootSubAssembly%>" />
     </jsp:params>
Would output "<%=rootSubAssembly%>" as the parameter value, rather than the dynamic value specified in the JSP above.
Any ideas? We'd like to benefit from using the plugin tag over object/applet if at all possible.

Fatal Error During Solution Center Install - "Key Not Valid for Specified State"

I have encountered an error while trying to install HP Solution Center for my J6480 All-In-One. The software I'm installing is "OJJ6400_Full_10.exe"
I can get past the installation option selections (i.e., the screens that allow selection of which components you want installed) as well the online check for updates to the software. However, shortly after that I get a fatal error the full text of which are:
Error Situation Code: 23551631
The following lines were retrieved from the installation error logs.
Now Launching=X:\hpzmsi01.exe -m dot4wrp "-*"
".\autorun_network.inf" "-networkonly" -| XXX -f X:\DIVins??.DAT
Error message received: Key not valid for use in specified state.

Your help is appreciated. Thanks.

Hey @redleader74,
At this time I am going to have you unlock the hidden System Administrator Account and attempt an install under there. Ideally, if everything installs fine you should be able to log back into your normal User Account and the complete software and driver package for your HP Officejet J6480 All-in-One Printer will be installed and functional. Can I please have you follow the steps below.
Step 1: Uninstall Drivers:
Click on your Start menu
Select All Programs
Select the HP folder
Select your HP Officejet
Select Uninstall
Please follow any onscreen prompts to complete the uninstall. Once the uninstall is complete please proceed to the next step.
Step 2: Clear Temp Files:
Click on your Start menu
In the 'search programs and files' box located right above Start after you click on it, type %temp% and hit enter on your keyboard
When the Temp folder opens, select Ctrl + A at the same time on your keyboard. Everything in this folder will now highlight.
Select the 'delete' button on your keyboard. The Temp folder contains temporary internet files. No actual files or folders on your computer will be affected by deleting the Temp files. Should a Temp file still be used than you will automatically get the pop up to 'skip' that item.
Close the Temp folder once it is emptied
Right click the Recycling Bin on your desktop and select Empty Recycling Bin
Step 3: Unlock System Administrator Account:
Click on your Start menu and under the 'search programs and files' box type CMD
CMD will populate as a search option above, just right click on it and 'run as administrator'
Once CMD (Command Prompt) opens, type net user administrator /active:yes and hit enter
Next, close CMD and restart your computer
When your computer comes on log into the new Account that should show. It will be called Administrator and will not have a password on it.
If your computer automatically logs into your account after restart than go to your start menu click the arrow beside 'shutdown' and choose 'switch user'. Now log into the Administrator Account we just unlocked
Step 4: Install Device:
Under the Administrator Account please click here to download the latest drivers for your printer.
Once the website opens select the Download button on the top left
Once the download is complete please follow the onscreen instructions to install your printer
Once the installation is complete, please test the functions of your HP Officejet to ensure that everything is functioning properly now. If everything installs fine, log out of the Administrator Account and back into your normal User Account. All the Software and Drivers for your product should show installed now on your Account. Once you're logged into your User Account please test your HP Officejet again to verify that your print and scan functions are still working.
If everything works fine, you will want to Hide the Administrator Account.
Go to your Start menu and under the 'search programs and files' box type CMD
CMD will populate as a search option above, just right click on it and 'run as administrator'
Once CMD (Command Prompt) opens, type net user administrator /active:no and hit enter
Next, close CMD and restart your computer
Please let me know if these steps resolve your issue. Good luck!

Error VISA (Hex 0xBFFF001E) The specified state of the attribute is not valid, or is not supported as defined by the resource.

Hi,
First of all I need to say that I just beginning with the instrument control using Labview. For this reason, it's possible that the problem that i have would be easy to resolve. However, I have been looking for any solution for the forum, but unfortunately I can't fint anything.
Then the situation is the following: I'm trying to connect a power analyzer (Yokogawa WT1800) with the PC through GPIB. To achieve this objective I use the Agilent 82357B USB/GPIB Interface. The connection is done properly because I can see and comunicate with it through the NI MAX explorer.
In order to achieve the instrument control using Labview, I have downloaded and installed the Yokogawa WT1800 driver (ykt1800 Instrument Driver) using the NI Instrument Driver Finder tool. The problem that I have is that when I execute the provided examples I find the following error:
Error -1073807330 occurred at Property Node (arg1) in Yokogawa WT1800 Series.lvlib: Initialize.vi -> Yokogawa WT1800 Series Measure Continuos Normal.vi
Possible reason(s):
VISA: (Hex 0xBFFF001E) The specified state of the attribute is not valid, or is not supported as defined by the resource,
I tried to change the input arguments of the Visa open vi because I think that is there where is the problem but I can't achieve any solution. In the following image is attached the block diagram of the initialize.vi:
Any help is appreciated.
Thank you.
Solved!
Go to Solution.

Hi,
The Vi should work, I used it with a NI USB-GPIB interface. Can you use HighLight execution to see which property node is failing. Maybe your interface does not support the used property node.

Outlook 2013 - Password change breaks S/MIME Certs "An error occurred in the underlying security system. Key not valid for us in specified state."

AD password change comes up, user changes password.
Tries to send signed or encrypted email with a Comodo S/MIME certificate, and gets the following error:
""An error occurred in the underlying security system. Key not valid for us in specified state."
I now have two reports of this error - one on Windows 7, and one on Windows 8.0 (remote user).
The one on Windows 8.0, we tried removing their S/MIME cert from Outlook/Windows and re-adding, this did NOT resolve the issue.
Plan was originally to have the 8.0 user ship their machine in, and wipe it, since nothing else could fix it and I wasn't finding anyone else with the same issue. Now that I've got a second user with the same issue, its looking like a bug/issue and
not a random glitch.
Thanks in advance for any and all help with this!

JSP-Editor not working properly

Hi everybody,
I am working with ISA5.0 and NWDI. I have checked out the Web-Module Project crm/isa/web/b2b.
Now I would like to modify JSP-Files. Unfortonately the JSP-Editor is not working properly.
The JSP-Editor cannot resolve references to Tag-Libraries like
<%@ taglib uri="/isa" prefix="isa" %>
Furthermore I get Errors with JSP-Includes
<%@ include file="checksession.inc" %>
The JSP-Editor does not show any other compile errors until the above mentioned errors are resolved.
So the JSP-Editor does not help with compile errors.
I have tried to use Lomboz instead, but due to the modularization in ISA5.0 and NWDI (ie the Taglibraries are defined in a separate module) I did not get it to work either.
Does anybody have experience on how to get the JSP editor to work properly?
Thanks for your help,
Andreas

Highlite the clip in the timeline, control click on it and choose "send to soundtrack as an audio file project" in the pop up menu. Don't do an "open with editor". This should work.
If it doesn't and it's just the one clip, you could launch Soundtrack and then open that clip as an audio project . . . don't do a open with editor, just open it directly. Make your adjustment and save over writing the file with the new audio. You may want to copy the clip first as a backup. When you open your FCP project, you'll have to re-link the clip. Once you do it will show up with the new sound.

ERROR: "key not valid for use in specified state" when updating to Lightroom 5.6 in Win8.1

While doing a routine update from Lightroom 5.5 to v5.6 in Win 8.1, the installation halted at the start of the installation with the vague error message, "key not valid for use in specified state". Although v5.5 was working just fine, the install routine deleted the v5.5 application files. I rolled back to the previous system restore point (set just prior to the install) and recovered the executable files. However, now the 5.5 files won't open the default catalog, none of the backups, or even create a new catalog.
As v5.x was purchased as an update to v4.x, I've tried to reinstall the original Lightroom v4.x app from the factory disk. I get the same error.
Suggestions?
Thanks. Dan

I have a similar problem to Dan. while doing a routine upgrade from Lightroom 5.5 to 5.6 I got the
: "key not valid for use in specified state"
error and now Lightroom has completely disappeared. I've tried to uninstall, but there is nothing to uninstall. Going back to try to install the original 5.4 just results in the same error.
A problem may have been that I closed Lightroom when the upgrade started to download. It then re-opened again when the install was halfway through., I assumed that was an error and closed it. just after that the error first appeared in the installer.
I still had an older version of lightroom 4 installed. I've uninstalled it, and that didn't make any difference.
I've also tried removing anything in the registry left over from the old installs and that didn't help either.
Any suggestions?

but even after doing all these steps, the error still persists!. and am not deploying into a remote server, the dev env is in a VM, where sp 2013, vs 2012, sql 2012 are installed.
just wanna share one note: there is a isue in my search admin component. index was reset due to some reason. and from that time onwards my search full/incremental crawls were not working!
will this cause an issue in my wsp deployment ? i hope it wont, still asking...
can anyone help me how to resolve this error.because this is a show stopper for me for the last few days!
help is highly appreciated!

This issue cause because of feature activation failure while WSP deployment.
when you create a WSP using visual studio, it creates WSP package with default deployment configuration settings.
Please restrict feature activation configuration, this will help you to troubleshoot this issue.
- Click on Project in WSP and press F4, it will open "Project Properties"
- set "Active deployment Configuration" - as "No Activation"
- you can activate this features in required sequence after deployment using Activate-SPFeature

Error_27_Error occurred in deployment step 'Activate Features': Operation is not valid due to the current state of the object.

I created a SharePoint 2013 farm solution project in Visual Studio 2013 (running on the same machine where SharePoint 2013 server is running) with
event receiver. I added web.config at project root level to store connection string (I'm working off external SQL DB) and got the following error during deployement:
Error 27
Error occurred in deployment step 'Activate Features': Operation is not valid due to the current state of the object.
When I commented out the ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString; the error went away. Am I missing something or not supposed to add my own App.config to SharePoint project solution?

Hi,
From your description, you might want to store your connection string in web.config and there is an error during deployment.
It is recommended to store the configuration data of SharePoint solution in either property bags or hierarchical object store.
The links below will provide more information about this:
