Installing GWT

Now we will set a wonderful framework GWT.This article does not claim to originality, similar articles you can find a lot, but still I decided to write a step-by-step man installation, since my first topic.You can write your application in your favorite editor, but I decided that if there is an opportunity to tie gwt to such a wonderful development environment like Eclipse, then write and use will.

So what we need to get started:
1. Download GWT. 2. Download Eclipse. I rocked version of Eclipse Classic. 3. To force to work the whole thing.In General, installation of GWT, and Ecliplse does not cause problems — just razorwire in neobhodimoe place and all.Now screw the GWT to Eclipse.First things first, you need to set a variable GWT_HOME. It is simple — the Main menu = > Windows = > Preferences...Then, under Java = > Build Path = > Classpath Variables create a new variable (New). Call it relevant GWT_HOME and set the folder where you unpacked GWT.That's all. You can now create a project. This is done as easy as anything else. In General, the creation of the project, the comrades of Google divided into 2 parts: 1. Create a project template. 2. Creating the application template.The first part is to just go to the folder Kula unpacked GWT and write in the console:projectCreator -eclipse MyFirstGWTApplication -out d:\Projects\MyFirstGWTApplicationthen you will see a notification about the generated files.Further on the second point — never left you write:applicationCreator -eclipse MyFirstGWTApplication -out d:\Projects\MyFirstGWTApplication EN.habrahabr.client.MyFirstGWTApplicationAgain, look what was created. If everything is OK, then import the project in Eclipse:File => Import => General => Existing Project into WorkspaceFurther all is simple, if you are going to write one, then I have nothing else to do. If provides team development, it is necessary for the project to determine the placement of the libraries through GWT_HOME, which we created in the beginning.To do this go:Project => Properties => Java Build Class => Libraries. We find there gwt-user.jar removed it. Then Click Add Variable => Select GWT_HOME => Click Extend... => Select gwt-user.isochrones the whole thing. That's not all. Similarly, it is necessary to specify the Classpath for the project. Run => Open Debug Dialog => Java Application => MyFirstGWTApplication => Classpath => gwt-dev-wondows.jar => Remove => Advanced => Add Classpath Variables => GWT_HOME => Extend => gwt-dev-wondows.jar => Ok.Phew, now everything seems to be. Press Ctrl+F11 and see what happens.The application is simple. Possible problems with encoding when using Cyrillic characters. Solved by placing the appropriate code pages for the editor and Eclipse for the project.

ODBC Firebird, Postgresql, executing queries in Powershell

Изображение
Sometimes, system engineers may need to obtain specific data directly from the DBMS by means of Powershell. In this article I want to demonstrate two methods of operating firebird, postgresql through the odbc driver and client library. let's Start with the firebird and work with the database through the ODBC driver, you first need to register in the system client library GDS32.DLL, its bit width should be the same as the ODBC driver which should be installed next, download on the manufacturer's website , be sure during installation you need to tick on the registration of the library. Next install itself ODBC, who also take on the manufacturer's website , do not forget that the bit size should match the bit count of a previously installed client. Now actually have a powershell script, it was based on example in C# for postgresql. the $dbServerName = "localhost:base.gdb" $dbUser = "SYSDBA" $dbPass = "masterkey" [string]$s

this weekend, Kiev will host a very cool event Garage48 — the idea is that for two days to create a startup. In the “create “ includes everything needed to present your business idea, qualify, technically, to bring it to life, and then be able to sell it to strict spectator and wise mentors. This event was invented in Estonia and has already managed to visit many countries of the world. Finally, Garage 48 has reached the Ukraine: from 11th to 13th may we occupy the Library of KPI , which is located on the Avenue Victory 37 and start enjoying foreign mentors (they will guide you in the right direction to create a startup and guide you on the right path, if you go into the jungle), as well as the company of their colleagues and event organizers — representatives of Garage48 Foundation And IT DOU-activist Vicky Zorbas. On Friday we will get acquainted with the ideas of the participants, will select the best ideas and form teams. Saturday morning will see which team surv

The Ministry of communications wants to ban phones without GLONASS

Today in the Ministry of communications submitted the bill , according to which in Russia it will be possible to use only those mobile phones that include support for the GLONASS navigation system. Although it is not clear how this will be monitored, most likely, we are talking about banning the importation and sale. This decision was taken in order, and I quote in order to ensure the stability of the unified telecommunication network of the Russian Federation in various conditions. Requirements (in the case of the adoption of this act) will apply to manufacturers and sellers. To monitor the implementation of law be entrusted to Roskomnadzor. How has this come? For me personally this news is not very surprising (and not only because this is another project state silly the Duma), not so long ago there was another similar initiative, the essence of which was to translate public transport to use the system "To the end of the year practically the whole of Moscow is covered
