Some time ago I’ve posted about using multiple -exec options for find command which can be used to find in what JARs particular class lies. Below you can find enriched and more intuitive/detailed solution for finding your class in a bunch of JARs: #!/bin/bash if [ $# -lt 1 ] then echo 'Usage: jarfind CLASS_NAME [DIR_WITH_JARS]'; exit 1; fi WHAT="$1" if [ $# -eq 2 ] then WHERE="$2" else WHERE="." fi FIND_RESULT=`find "$WHERE" -maxdepth 2 -name '*....
When you create a deployment using Arquillian (great test runner for testing your Java EE code in the container of your choice: jBoss, Glassfish, OpenEJB, … either in embedded, managed or remote mode) remember that the name of the deployment archive file is the exact filename that will be executed in the container. It does make a difference if you use *.war or *.jar for your deployment, so beware the following construct if it’s not exactly what you intended to do:...
If you want to add your classes (or any other resources) to your ShrinkWrap archive to a non-root location, you can use the following: @Deployment public static JavaArchive deploy() { // This is the classes and resources archive JavaArchive ar; ar = ShrinkWrap.create(JavaArchive.class, "resources.jar") .addPackage(TestClass.class.getPackage()); /* * The 'ar' archive will be added to the 'yourDir', so you'll * end with test.jar#/yourDir/TestClassPackage/TestClass.class */ JavaArchive endArch; endArch = ShrinkWrap.create(JavaArchive.class, "test.jar") .merge(ar, "yourDir"); endArch....
I was trying to execute several commands on a single record found by the GNU/Linux find command. The first attempt was to create something like: find . -name "*.pdf" -exec echo 'test' && echo 'test2' \; But it’s not the way the find command works. If you want to execute more than one command for each hit, you should use multiple -exec actions: find . -name "*.pdf" -exec echo 'test' \; -exec echo 'test2' \; I used this feature to list JAR files in a specified location along with classes they consist of:...
Servlets 3.0 in Java EE 6, brings new interface called ServletContainerInitializer. The name is very self-explanatory, but the question is – how it’s different from the ServletContextListener? Well, technically, the ServletContainerInitializer is not a listener – it is an initializer and it’s executed before any servlet context will even be ready. You can use this initializer to do some programmatic servlet/filters/listeners addition (which is also possible in Servlets 3.0!). The ServletContainerInitializer....
When you create a *.jar file using jar command-line tool, it is worth to remember that the order of arguments does matter, so: jar cmvf projects/myTags/etc/MANIFEST.MF myTags.war myTags means that you must firstly provide the manifest file (m), than the JAR filename (f). If you use the same order of arguments but change the switches like this: jar cvfm projects/myTags/etc/MANIFEST.MF myTags.war myTags the command will not be executed. According to the switches, your first argument should be the JAR filename (f) and then manifest file (m)....
