I wanted to add a jar file to a Maven project but I don't want to create an artifact and install it to the repository. This is a third party jar that will be used only for this project and not shared with other projects, so it's convenient just to drop it in the project folder and package it with the target. Maven provides the system dependency scope to do just that: <dependency> <groupId>com.thirdparty</group...

Maven is a powerful yet complex tool. When I started learning Maven, the first obstacle was, of course, its complexity. The second, was the lack of documentation that can get me off the ground quickly. This tutorial is an attempt to create a pragmatic guide that aims to get you familiar with Maven in the quickest way possible. The main theme is to get you on some hands on experience to start out and lead you through the creation of a simple Java EE project as quickly as possible. Instead of trying to give you a good read, I try to get you on the journey right away. The topics are roughly ordered by the logical sequence but you can jump around in any way...

Some dependencies may not be available from the central Maven repository, or any public repository (for example, due to licensing issues). You can install these to your local repository with the Maven Install Plugin : mvn install:install-file -Dfile=path-to-your-arti... Only the file parameter is required.

In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print <p>john</p> <p>steve</p> <p>mike</p> with custom tag <my:foreach> : <my:foreach var="who" value="john steve mike"> ... These are the files: pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... src/main/java/com/example/UIForeash.java : package com.example; import java.io.IOExcep... src/main/resources/META-INF/faces-config.xml : <?xml version="1.0" encoding="UTF-8"?> <faces-c... src/main/resources/META-INF/foreach.taglib.xml : <?xml version="1.0" encoding="UTF-8"?> <facelet... How to use: Put the JAR file generated by the above project in the WEB-INF/lib folder of the web app. If the web app is a Maven project, just add the taglib project as a dependency:...

This is a step-by-step example to create a really simple facelet taglib (in JSF 2 with Maven). Create a simple Maven project with: mvn archetype:create -DgroupId=com.example -Dartif... Three files are created as a result: pom.xml src/main/java/com/example/App.java src/test/java/com/example/AppTest.java This project should be able to build with: mvn package Add facelet API dependencies to pom.xml : <project xmlns="http://maven.apache.org/POM/4.... The compiler plugin section is optional. Remove src/main/java/com/example/App.java , create a new Java class as the facelet Tag Handler ( HelloTagHandler.java ): package com.example; import java.io.IOExcep... This tag handler simply prints a "Hello" message. Create facelet tag declaration file src/main/resources/META-INF/hello.taglib.xml : <?xml version="1.0" encoding="UTF-8"?> <facelet... Build the JAR with mvn clean package Optionally, install it to the local repository: mvn install To use the taglib, simply drop the...

This error happened when I loaded a JSF page, using Apache MyFaces. From the stack trace it looked like the XML parser failed, but in reality the runtime was not able to load the class specified in the handler-class element - a typo in the class name! That's the price you pay for wiring together components with XML! This was the stack trace: Caused by: org.xml.sax.SAXException: Error Handlin...

Facelet tag library descriptors can be specified in one of two ways: In web.xml , as <context-param> : <context-param> <param-name>javax.faces... where javax.faces.FACELETS_LIBRARIES is interpreted as a semicolon ( ; ) separated list of paths, starting with "/" (without quotes). Each entry in the list is a path relative to the web application root, and is interpreted as a facelet XML tag library descriptor. The parameter facelets.LIBRARIES is an alias to javax.faces.FACELETS_LIBRARIES for backwards compatibility reasons. Via auto-discovery, by placing the XML tag library descriptor within a jar on the web application classpath (for example, under the folder WEB-INF/lib ). The file should have a name suffix .taglib.xml , and be placed in the META-INF folder of the JAR file.

I want to add my own file to the META-INF folder of maven generated JAR. This is how: Create folder resources/META-INF under src/main (if it doesn't exist already). Copy the file to resources/META-INF . Maven package will automatically add the file to the finished JAR.

Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app : <project> <modelVersion>4.0.0</modelVersion>... Create a directory named ear under javaee-app . Create pom.xml under ear : <project> <modelVersion>4.0.0</modelVersion>... Modify pom.xml in the webapp directory so that it looks like this: <project> <modelVersion>4.0.0</modelVersion> ... Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....
