Here is the list of all JAR tutorial. A Java library contains code which you can access and use in your Java project. The deployment format of a Java library is a JAR file. A JAR file is a Java archive based on the pkzip file format. JAR files are the deployment format for Java. A JAR can contain Java classes and other resources (icons. How to use classes files? Ask Question I read the Java tutorials on Sun for JAR files, but I still can't find a solution for my problem. I need to use a class from a jar file called, I downloaded the file, and tried executing it (I found out yesterday files can be executed by double clicking on them. To perform basic tasks with JAR files, you use the Java Archive Tool provided as part of the Java Development Kit (JDK). Because the Java Archive tool is invoked by using the jar command, this tutorial refers to it as 'the Jar tool'. As a synopsis and preview of some of the topics to be covered in this section, the following table summarizes.

You might have sometimes downloaded some applications in your machine and you would have been asked to extract the jar file to access all the files of the application. This jar file is nothing but the bundle or group of multiple Java class files merged into a single archive file. The JAR file can store many kinds of files like images, video, or audio files. The JAR file decreases the downloading time because the JAR file is the compressed version of a normal file therefore the size is reduced. If it is not there, then you can also use decompression software to access the files in the JAR. Keeping you updated with latest technology trends, Join TechVidvan on Telegram. The basis of the JAR file format is the zip file format. Istakni oči i usne jer je Nova godina! Makeup tutorial - Sanja The canonical reference for building a production grade API with Spring.

This tutorial explains the usage and purpose of Java JAR files. 1. Defining and using Java libraries. What is a Java library? A Java library contains code which you can access and use in your Java project. The deployment format of a Java library is a JAR file. The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available. See Java Language Changes for a summary of updated language features in Java SE 9 and subsequent releases. Aug 05,  · In this tutorial, we set up a simple Java application with a main class. Then we looked at three ways of creating jar files: using the jar command, with Maven and with a Maven Spring Boot application. After we created our jar files, we returned to the command line and ran them with an inferred and a specified main class.

Generating source code can save you time in your projects and can reduce the amount of tedious redundant programming. Generating source code can be powerful, but the program that writes the code can quickly become very complex and hard to understand.

One way to reduce complexity and increase readability is to use templates. It is located in the org. This article also provides a short reference to the JET syntax.

Contributed by Remko Popma, Azzurri Ltd. Last update: May 31, for EMF 2. Before creating our first template, you'll need the EMF plug-in version 2. If you haven't installed it yet, install it now before continuing with this tutorial.

A JET template is a text file with a file name that ends with "jet". I will follow the EMF convention of appending "jet" to whatever the file extension of the generated code would be, so.

Let's follow tradition and start with a template that creates the message "Hello, world". We will create our first template using the following four step process:. After pressing the Next button, select the project you've created and click Finish. The wizard adds the JET Nature to the project creating a templates folder under the project root as shown in the image below.

Also, a JET Builder is added to the project that will automatically translate every file in the templates folder with a file name ending in "jet" to a Java class. Before creating our first template, let's make sure that the src source folder of the project is the destination folder of the translated templates.

Right-click on the project and select "Properties" from the popup menu. In the Project Properties dialog, select JET Settings on the left-hand menu and enter "src" the name of your source folder in the "Source Container" text field. Note: you can specify multiple folders in the Template Containers field, separated by a space or a semicolon.

However, if templates in different folders have the same filename, only the template in the first folder will be translated automatically by the JET Builder. If you want all templates to be translated, make sure they have different file names. The JET builder will now translate all templates to Java source files in the src folder of the project. Now we create our first template. Select the templates directory as the parent folder, and call the file helloworld.

You will get the following error when you press the OK button: "The jet directive is missing in 'helloworld. Fortunately, this does not mean that there is a real problem, just that the JET Builder tried to translate our template as soon as we created it, and discovered that it is still empty.

Press Close to close the error dialog. Open the helloworld. When you save the template file, it will automatically be translated by the JET Builder. Because we specified package hello and class HelloWorldTemplate in the first line of the template, the builder creates a hello package in the src folder and saves a Java file HelloWorldTemplate.

This Java class is the result of translating the template and is called a template implementation class. This class has a method called generate. This is the method that generates the code indicated in the template. We can create an instance of the HelloWorldTemplate template implementation class and invoke its generate method like this:.

To recap, we just created our first template and generated some code with it. The result may not have been very impressive, but now we are all set up and we can start to explore what JET can do for you.

The next step is to pass an argument to the template. Add a new JET template file or change the existing one to the following content:. Again we create an instance of this template class, but this time we pass a string argument to the generate method:. The argument you pass to a template can be any object. In the previous example we passed a string as the argument to the generate method, but in your application you probably want to pass in your own model object. If the argument is not in the java.

A jet directive with an imports attribute looks like this:. The JET Syntax Reference section of this article gives more details on the jet directive and its attributes. In the next example we will create a template that generates XML code. To stick to the EMF convention of appending "jet" to whatever the file extension of the generated code would be, we will save this template to a file called importdemo. Note that we pass the template a java.

List object that contains the data to use when generating the XML. The code below shows how to invoke the template instance. We create a list and pass it to the generate method of the template implementation class:. This is a very simple example that creates very simple XML. When you do this, you may find it more convenient to create a special class that is a better model of an XML document than a java.

Generally, the more complex your JET template becomes, the more logic you will want to push into the model object that you pass to the template, to keep your templates readable. We will explore this further in Part 2 of this tutorial.

A neat feature of JET is that you can change the tags that mark scriptlets in the template file. To change the tag markers, add a startTag and an endTag attribute to the JET directive on the first line of the template, like in the example below. In the previous section we have looked at creating JET templates, how to set up the JET Nature to automatically translate templates into Java implementation classes, and how to use these Java implementation classes to generate code.

In this section we will take a closer look at the Java implementation classes that are the result of translating a template. We will see why we can use the implicit objects argument and stringBuffer in a template, and also look at customizing the translated implementation class by providing a custom "skeleton". A JET template is translated to a Java implementation class. There are some objects in the Java implementation class that can be referenced directly in the JET template.

The following example demonstrates how the implicit objects argument and stringBuffer can be used in a template. Notice that the generate method of the Java implementation class takes an Object parameter called argument.

This is the same object as the argument in the second line of the template. Also, notice how the Java implementation class uses a StringBuffer object to collect the resulting generated code. This object can be referenced directly in the template by its name stringBuffer. The generate method of the TranslationDemoTemplate class above is said to be part of the implementation class "skeleton". The default skeleton used by the JET engine looks like this:. The skeleton definition looks almost like a normal Java class, except for the class name.

Furthermore, the skeleton definition has the generate method that we have seen earlier. By changing the skeleton you can customize a template implementation class, for example make it implement an interface, or change any other feature of the class. For example, suppose you want all your template implementation classes to implement an interface.

The interface could look something like this:. We can tell the JET engine that we want to use a custom skeleton by setting the skeleton attribute of the jet directive on the first line of the template file. The value of the skeleton attribute is a URI that points to a file where the custom skeleton definition can be found. To try this, first create a new file generator.

Open the generator. This file is our custom skeleton. All templates that use this skeleton will be translated to classes that implement the IGenerator interface. To use this skeleton, add an attribute skeleton to the jet directive of your template, like this:. Note that the translated template now implements the IGenerator interface, and the generate method now has the comments we specified in the generator.

This is one example of how to customize a translated template with a skeleton definition. Skeleton definitions can also contain extra methods, inner classes, etc. You'll need to experiment a little to see what else is possible.

A JET template is translated into a Java implementation class. This implementation class has a method that can be called to obtain a result string. This method is usually called generate see also the skeleton attribute of the jet directive. If no skeleton attribute is specified in the jet directive, the Java implementation class has the following implicit objects, which can be referenced in the JET template:.

Directives affect how a template is translated, but do not produce any output in the generated String when the template is invoked. The jet directive defines a number of attributes and communicates these to the JET engine. A JET template file must contain a jet directive on the first line of the file, or the template file cannot be translated. Any subsequent jet directives are ignored. Unrecognized attributes result in fatal translation errors. The following directive indicates that the template should be translated to a Java implementation class called HelloWorldTemplate.

The implementation class should import the java. The included file may have JET scripting elements which will also be processed. This directive has one single attribute, file. The value of this attribute is the URI of the location of the file to include.

In addition to source releases, I have also written a number of tutorials designed to help people learn how to use code in a creative context. Here is a list of the. In this article you will learn how to create JET templates, how to use the JET Nature and JET Builder to automatically translate templates into Java classes, and.
