Download JAR files tagged by loaded with all dependencies

A tool for generating "wrapper" JAR files. A wrapper JAR file contains a Class-Path manifest attribute listing a group of JAR files to be loaded from a common codebase. It may also, depending on applicability and selected options, contain a JAR index file, a preferred class list and/or a Main-Class manifest entry for the grouped JAR files.

In brewing, you prime nearly finished beer with a little extra sugar (or similar fermentable product) just before bottling to help the beer carbonate. In Java, Prime adds a little structure or manipulates data in your database just before starting up your application. Prime leverages Flyway to deliver "sugar" to your database - we just do a little bit to package it up to run when your war is loaded.

In order to properly test OSGi-loaded t2ference modules we need a module that is entire external to t2reference and to the test cases. If the test implementations are included in either the api, core implementations or test modules they will be loaded by the root classloader of the test runner - by putting them in an independent artifact we allow them to be loaded through various SPI discovery mechanisms as they would be in a 'real' environment.

manage jar dependencies for gems and keep track which jar was already loaded using maven artifact coordinates. it warns on version conflicts and loads only ONE jar assuming the first one is compatible to the second one otherwise your project needs to lock down the right version by providing a Jars.lock file.

JPA Security is an Access Control Solution for the Java Persistence API (JPA). With JPA Security your access control can be performed in the database. You may query the database for all objects of a certain type and will receive only the objects you have read access for. This filtering is performed in the database. Unaccessible queried objects will not be loaded into memory. JPA Security enables you to completely remove security-related code from your code-base. All access control may be configured via Annotations or XML. With JPA Security you do not have to change your access control paradigm (but maybe you want to, when you see the great capability of JPA Security). You even can mix access control paradigms easily. JPA Security is not designed to replace current security solutions, but to extend them. It integrates smoothly into the security mechanisms of the Java EE Platform, but may be used with third-party frameworks like Spring Security or in Java SE, too. With the extensibility of JPA Security it is easy to provide your own access control paradigm, access rules storage or login mechanism.

A powerful library for creating classes during runtime, facilitate the use of reflection, search subtype and much more...

According to Docker best practices a Docker container should not be up if the process fails to load properly. Apache Tomcat deploys all the web applications loaded in its webapp folder. This is a resilient solution for web applications not influencing the application server. However, In a Docker environment according to best practice, the process should fail in case the web application failed to initialize properly. By adding the additional jar created by this project to Tomcat classpath and adding the new listener in the Tomcat conf/server.xml the user can make sure the Tomcat process fails in case there is an initialization exception in their web application which will cause the Tomcat used the tomcat container to abort in immediately indicate that there was an initialization error Abort tomcat when a webapp fails to deploy in Docker container Docker container best practice. Tomcat does not stop if a webapp fail to deploy and the container will continue to run. By adding this listener the tomcat will abort in case the Tomcat fails to deploy the webapp, And the container will not start. You will need to place the listener in Tomcat server.xml and set the Tomcat classpath to contain this jar

In some data processing tasks we need to use huge maps or sets that are bigger than available JVM heap space or they are loading too slow to standard Java or Scala Maps. We use TSV format (text file with tab separated columns) for persist this kind of Maps or Sets. Some columns are used as a key and rest of columns as a value. Idea of this library is simple. We can prepare these maps once (sort by key), store it to file and then use it as memory mapped file. Searching key in sorted file has log(n) complexity. If more processes uses the same memory mapped file, it exists in memory just once (on Linux). This file can be loaded lazy by OS.
