I'm following this tutorial : https://netbeans.org/kb/docs/web/mysql-webapp.html
All is working until this :
The two resources don't display in each category.
I have still continued the tutorial and i get this error :
javax.servlet.jsp.JspException: Unable to get connection, DataSource
invalid: "java.sql.SQLException: No suitable driver found for
jdbc/IFPWAFCAD"
I have added the Connector in the libraries...
Can someone help ?
We had this tutorial assigned as a class exercise and we all ran into the same problem. Something with updates puts the "glassfish-resources.xml" in the WEB-INF section of your project. Left-click and drag this file into your "Server Resources" folder then right-click on your project folder. You should now see the jdbc/IFWAFCAD in the JDBC Resources and IfpwafcadPool in the JDBC Connection Pools of your GlassFish Server Resources.
I also had followed this document and got a similar error. Because of, I was wrong with "Referencing the data source from the application"."For Resource Name, enter the resource name that you gave when configuring the data source for the server".
I could run successfully after correct it.

i am new in talend open studio and i found no way to read dbf files .
i found actually 2 blocking ways where i am stuck each time with different errors .
i tried first to downlaod from exchange.talend , tDBFInput component and it shows an exception "dbflib.CorruptedTableException: Number of field descriptions in file could not be calculated" each time i try to run the job after putting the dbf file in that componenet .
i also tried to perform a jdbc connection using a dbf driver i downloaded , after installing it as external jar , i cannot find out the driver class , i can select the driver and it is added from the list of drivers but i cannot find the class ,which class to use .and also how to later on make the connection to a file not a table .
i also tried a second tDBFInput component that i downloaded from the exchange.talend web site but it always shows MASHAPE KEY that i need to configure , where i have no idea what value it should take , i see people saying it should be an URL pointing to an API and you also must know the authentication needed to request that url .
i even tried to find solution in edureka but no solution found .my question was detailed there with screen shots .
can anyone who extracted data from dbf FOX pro files in version 7.x tell me how to do it?
One of our client has a DNN Site. There was some issue happened in the server and the drive that host the site is crashed. Luckily the database was in other drive. So we have database of the site. I have a back up of the site in my local system too. Now I need to restore the site. So My question is what steps should I perform exactly?
Below are some twists that I came to know recently:
There were other sites too and they were in different DNN version. Can we know from database which version of DNN was the sites running?
I tried to put my files on server and provide connection string of database. When I start the site, it complete the installation process, but shows me default DNN Page. Please see attached image for the same.
When I checked the Log file, it is throwing below error
Unhandled error loading module. ---> System.Web.HttpException: The
file '/Portals/_default/Containers/Xcillion/NoTitle.ascx' does not
exist
DotNetNuke.Services.Exceptions.Exceptions -
DotNetNuke.Services.Exceptions.ModuleLoadException: Unhandled error
loading module. ---> System.Web.HttpException: The file

DotNetNuke.Services.Exceptions.Exceptions -
DotNetNuke.Services.Exceptions.ModuleLoadException: Unhandled Error
Adding Module to ContentPane ---> System.NullReferenceException:
Object reference not set to an instance of an object.
Then I thought the site may use the inbuilt database (I am not remembering exactly what kind of database I set up). So I copied the site code in separate folder and tried to map this folder with IIS. And that is giving me below error:
DotNetNuke.Common.Initialize - The connection to the database has failed, however, the application is already completely installed, a 500 error page will be shown to visitors"
Can anyone tell me how can I recover this site?
Thanks in Advance.
Ouch!
Having the database (or databases) is a good start.
Look in the Versions table and the last row is the last DNN Version installed. Look in the Portals table to see which portals were created in that install.
The errors that refer to Containers refer to files that are missing from the site's file system. Your IIS configuration for the site points to the root of the file system.
The module load exception probably refers to a module's files that should be in /DesktopFiles/ModuleName.
So, if you have the database AND you have a copy of the files that correspond to the database, then put them all back, make sure that the connection strings are pointed correctly in web.config ... and cross your fingers.
If you have the DNN version and the correct database, you might try doing a clean install of the DNN, install the modules that you had installed on the one that crashed, and THEN swap the clean version's database with the one that you have -- actually a copy.
Make sure that you are keeping copies, and you may be able to reconstruct lots of things.
And, it goes without saying that you should take a blood oath about making good and regular backups, and storing them on a different disk.
I have created a sample WPF project, worked fine.
I added a MVVMLight project, made it a default startup project, and ran fine.
Now I added a class library project, and added an ADO.NET data model with "Code First From Database", and selected relevant tables, that gave me a good collection of entity classes.
I thought this way, I can keep my data model seperate from presentation and businesss logic layers, plus add additional target plateforms if needed and take the advantage of SoC.
So far so good.
Now I want to enable Migrations on my data layer only. I fired up Nuget console, selected dataLayer project in the "Default Project" drop down. Issued Enable-Migrations command and very first error I got was
"No connection string named 'dpFinDataModel' could be found in the application config file."
Now I modified Startup project - i.e. Mvvm project's App.Config to add App.Config details from DataLayer project.
Tried to rerun "Enable-Migrations", and following error occured:
PM> Enable-Migrations
The project 'dpFinMvvm' failed to build.
Am I doing something wrong here?
Will this approach work?
Thanks for all your help.

1) PM> Enable-Migrations would get an error if your project itself contains errors.
Try going through your code such as in debug mode and check if you have any build errors then try.
2) And for your config file error you may have not referenced it properly, try this tutorial to solve your issue.

To start with, I would like to stress that I do know how to define XML Namespaces correctly in my XAML files. This repeated error is not caused by an mistake in my code. The problem does not stop my project from being built successfully, or running and the mentioned Converter class works perfectly.
When I build the project, the errors disappear. However, the designer show the familiar error message:
When I click on the 'Reload the designer' link, the errors return. The worst part of this problem is that I lose all Intellisense on these views.
The error highlights these namespaces:
But you can clearly see that they have been declared correctly:
I'm sure that I have found a solution for this problem before, but after an extensive search just now, I can only find a million posts relating to this error where users have actually made errors. Please also note that this was a brand new WPF Application and not downloaded from the internet or a network drive.
Is the project ON a network drive? XAML has issues with projects stored on a network drive. In corporate environments your Documents are often remapped to a network path, causing this problem for the default project folder.
Try like c:\projects\yourprojecthere instead?

I am a newby in the beautiful world of Microsoft Azure and made my first hello world website. The next step is to create a database (entityframework) but I get an exception while creating the database from PackageManagerConsole (PMC). I read a few posts on the web that explained that I need to add the startupprojectname to the PS command, but unfortunatelly that doesn't resolve my problem.
I have 2 projects in my solution.
"partyonwebsite" which is the startup project and obviously my website :).
"models" where I will design my models / entities.
In the "models" project I have the classes "User" and "UsersDb". UsersDb is the class that inherits from DbContext.
Now, when I execute the following line in PMC:
enable-migrations -StartUpProjectName "PartyOnWebsite" -ContextTypeName "Models.Users.UsersDb"
I receive the following (not very helpful) error:
System.ArgumentException: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
I've had a look at get-help enable-migrations and played around a bit but not a lot of luck.
Did anybody bump into the same problem? Or can you point me in the right direction to help me solve it?
Thanks a lot in advance!

Solved. If you run into the same problem, make sure that EntityFramework is setup correctly for your seperate "Models" project.
Open "Manage NuGet packages for solution" in solution explorer (right click solution in solution explorer)
Select "Installed packages"
Select "EntityFramework" and click "Manage"
Check your "Models" project (I checked both my website project and the "models" project)
Run your enable-migrations command again.
I also added a project reference from my Website project to the Models project, I don't know if that matters.
The command that successfully executed after my adjustments in NuGet:
enable-migrations -ProjectName Models -ContextTypeName Models.Users.UsersDb
Hope this answer helps another lost soldier in his path to get his first app running in Azure :).
Cheers,
