According to androidannotations.org in order to add support of android annotations to your Android Studio project using Gradle you need to perform a few simple steps. These steps are described on this page - https://github.com/excilys/androidannotations/wiki/Building-Project-Gradle
But as I discovered this is not so simple as it is described. Once you perform all the steps from the above instruction, you will be available to use annotations in the source code. Moreover, gradle sync process will be successful. But as soon as you decide to...

I think many people (who is interested in the J2EE developing) faced the situation when after deploying and running the project you see something like this in the address bar:

http://localhost
Let's start from the simplest part - removing root context from the address bar. In order to not show "Yourproject-war" part you can simply just...

In this short article I will show how to insert the line break inside the Primefaces component's value.
Let's imagine that we need to insert the line break in the value of the column in <p:dataTable>.
The simple code without line break:
<p:dataTable var="val" value="#{testMB.list}" paginator="true" rows="10" paginatorPosition="bottom" editable="true">

I have faced the issue with the <p:dataTable> when using rowEdit ajax event. Firstly, I tried to google some information regarding this and found out that many people faced the same issue.

In the previous post I told about how to upload file(image) to the database in J2EE application. Now I want to tell how to show this image on page. My toolkit is the same. So i'll use the Primefaces library for the UI.

The part of the .xhtml page that responsible for the viewing of the information:
<h:form...

In this "how to" I'll tell about the process of the uploading file to the database in J2EE project. My toolkit is consist of Netbeans IDE, Glassfish web server, UI library - Primefaces. Let's consider the example with the internet market.
Let's imagine that you have such an entity as a Product. The fields that described in the entity class are: name, description, price and image.
For now the main objective is to add Product to the database.
The part of the .xhtml page that describes the adding to the database:
<h:form enctype="multipart/form-data">

In order to describe the picture in detail we need at least two .xhtml pages and one backend bean.
Let's consider that we have two pages with such a content (use any code you wish instead of <...>. I will describe only navigation effect)
<html>
<h:head>...</h:head><h:body>...
<a href="index.xhtml">Homepage</a>
<a href="publications.xhtml">Publications</a>
...</h:body><html>
Now we need to transform these lines in something that will show us on wich of the pages...
