I am recently new here. I have a problem about Apache Wicket Framework version 1.6.0 using IDE netbeans 8.0 to Create Login Form and to connect in mysql database .I have many errors please reply on my problem
Wicket is unmanaged UI Framework. There is no way to use Wicket to connect to database.
You have to use any other mean to connect to database.
Here are some steps that might be of use:
1. Learn to access database in Java
Connect Java to a MySQL database
2. Process information obtained from Database
3. Use Apache wicket to display information obtained from database to user. In your case, IF user is authorized then redirect to other page.

Excuse me asking maybe silly/dumb
I'm Rookie self-taught developer
I trying to get my flutter app to work with my PostgreSQL database
Unforturnly I couldn't find anything related to Getting Flutter and postgreSQl to work togeather
All I can find is using Aqueduct a dart package which I was not able to install
https://medium.com/flutterpub/flutter-how-to-do-crud-with-postgresql-part-1-57d8d3652a31
as they couldn't find a library to install Aqueduct
Is there any other way I could get Flutter work with PostgreSQL?
Or there a way I could get Aqueduct to work?
Greatly appreciate your help in this.
For interaction of your app with a relation db you need a backend, in any technology, as the negotiator of both parties.I dont know aqueduct but you can try node js + express js as it is a popular backend stack, here a tutorial is quite simple to understand and setup, theres is also a js postgresql package called pg so you will need to add it to your node backend. I don't know how much knowledge do you have about http request/response, backend, frontend or http apis, so you should maybe study all of that before doing your project.

I need to save some data into mysql, let´s say "LONDON" and I can use Javascript , jQuery and Ajax, but NO node.js or PHP.
Is there any way to do it?
Thanks,
R.
There is no way to connect to MySQL server using only JavaScript, jQuery or Ajax directly because connecting to DB server to save or retrieve data is what server does which none of 3 can do alone.
However, there is service that does the server-like tasks for you.

Please take a look.
A solution for this problem would be to use the micro-services architecture and the RESTful Web Services.
Javascript could send the data to an URL and on the server side the data would be sent to the database.

I want to send log events to BAM 2.4.1 via client REST but I dont find any example about it so I need to know what is the endpoint url and some example about building of the json message to send.
Thanks in advance for any help
Currently, it doesn't have a REST API to publish events. Current options are listed here.
In addition you can use Analytics JavaScript (JS) API as well. It has this limitation.
Currently due to a limitation, client applications should be deployed
in the same domain as the Dashboard server. i.e -
DAS_HOME/repository/deployment/server/webapps

I successfully integrate the postgres and eclipse but unable to test the database. I need to know where can i get help if any suggestions would be appreciate.By the way i am using java. Thanks in advance.
Selenium is not the right tool here, as it is a tool for automating testing of web front-ends. You cannot directly test your database using this tool.
You can test an application like phppgadmin, but it isn't clear that is what you want.
A better approach is just to write test cases through jUnit and jdbc, in my view. That gives you better control and testing than you can via a web front-end and it is easier to solve the question of whether you want transactions to rollback or not (selenium poses this problem since it is indirect and tests a web app that interacts with the db over a stateless connection).

I see many Grails applications using version 1.3.3. Will upgrading our Grails 2.3.11 application to use mongodb-2.0.1 cause any problems.
If you want to see what changed between versions I suggest you look at the change log for the plugin.
Typically plugins which have issue trackers (on the plugin portal page for the plugin) have some type of change log within them.
