The recommended solution is to use the Class-Path line in the MANIFEST.MF file inside your jar to point to required libraries (relative paths are allowed) and then deploy all files together and invoking it with \"java -jar your.jar\"
Run this method before you do anything else, and you can completely ignore the external JAR files that Netbeans gives you, and just distribute the one. As an additional note, I used this method to install javax.comm, which didn't like being distributed externally. It came with a .dll file and a properties file. These files can be installed using the exact same method, but it's worth noting that the .dll file must be placed in the Java\\lib\\ directory and properties files go in the Java\\lib\\ directory (not in the \\ext folder).
Data Structure in java is defined as the collection of data pieces that offers an effective means of storing and organising data in a computer. Linked List, Stack, Queue, and arrays are a few examples of java data structures.
We know that Threads share Object resources, which can lead to data corruption because these operations are not atomic. Learn how we can achieve thread-safety in java using different methods. Read this post to learn about the correct usage of synchronization, synchronized methods, and synchronized blocks.
Java Thread dump provides the information of the current thread. A thread dump is useful to analyze performance issues with the application. You can use thread dump to find and fix deadlock situations. This post explains different methods that can be used to generate thread dumps in java.
Deadlock is a situation where multiple threads are waiting for each other to release resources causing cyclic dependency. This article discusses the situation in which we can get deadlock in a java program. How we can use Thread dump to find the deadlock and best practices to avoid deadlock in java program.
Before Java 5, the producer-consumer problem can be solved using wait() and notify() methods but the introduction of BlockingQueue has made it very easy. Learn how we can use BlockingQueue to solve the producer-consumer problem in java.
Java Thread Pool is a collection of worker threads waiting to process jobs. Java 5 introduction of the Executor framework has made it very easy to create a thread pool in java. We can use Executors and ThreadPoolExecutor classes to create and manage a thread pool.
hey thanks for this great information on multi threading in java. I have found this really helpful. Here you covered all the things regarding multi-threading and i was going through the same . It will be helpful if you post on thread priorities.
Type 'javac MyFirstJavaProgram.java' and press enter to compile your code. If there are no errors in your code, the command prompt will take you to the next line (Assumption : The path variable is set).
When saving the file, you should save it using the class name (Remember Java is case sensitive) and append '.java' to the end of the name (if the file name and the class name do not match, your program will not compile).
Before you continue make sure that you have read and completed the tasks in the Getting started tutorial to generate an All-In-One (AIO) project, which means selecting the org.alfresco.maven.archetype:alfresco-allinone-archetype Maven archetype when generating the project. The following information assumes that the AIO project was generated with the name my-all-in-one-project.
Looking into the generated AIO parent project we can see that we got a Docker Compose file (my-all-in-one-project/docker/docker-compose.yml) that will be used to build custom Docker images and run the project, one sub-project called my-all-in-one-project-platform that will be used to build Repository customizations, and one sub-project called my-all-in-one-project-share that can be used to build Alfresco Share UI customizations.
There are also the my-all-in-one-project-platform-docker and my-all-in-one-project-share-docker projects that are used to assemble (aggregate) all the Repository and Share extensions (there are usually more than one of each in a bigger project) and then build the custom Docker images with the extension(s) applied.
Note that if you have another Alfresco SDK project running, then you need to stop it first. Also, make sure that the following ports are free: 8180 (Share), 8080 (Alfresco Repo), 9898 (Share Debug), 8888 (Alfresco Repo Debug), 5555 (Postgres).If you want to change the ports see the properties section of my-all-in-one-project/pom.xml. This project file also contains the versions of Alfresco Repository and Alfresco Share that will be used.
The Repository extension is a Web Script that can be called with the following URL: :8080/alfresco/service/sample/helloworld.The source code for the Web Script is located here: my-all-in-one-project/my-all-in-one-project-platform/src/main/resources/alfresco/extension/templates/webscripts/alfresco/tutorials and here: my-all-in-one-project/my-all-in-one-project-platform/src/main/java/ com/example/platformsample/HelloWorldWebScript.java.
The Share extension is a custom Aikau page with a custom widget, you reach it with the following URL: :8180/share/page/hdp/ws/simple-page.The source code for the Page and Widget is located here: my-all-in-one-project/my-all-in-one-project-share/src/main/resources/alfresco/web-extension/site-webscripts/com/example/pages and here: my-all-in-one-project/my-all-in-one-project-share/src/main/resources/META-INF/resources/my-all-in-one-project-share/js/tutorials/widgets.
Looking into the generated Platform project we can see that we got a Docker Compose file (my-platform-project/docker/docker-compose.yml) that will be used to build custom Docker images and run the project. We also got a directory for our extension source code: my-platform-project/src/main/java and one directory with the Docker related stuff, such as the Dockerfile used to build the custom ACS Repository Docker image: my-platform-project/src/main/docker.

Below is a description of the content in the my-all-in-one-project-platform (typically named ) sub-project. This sub-project contains the source code entirely dedicated to the customizing the Content Services Repository.
Below is a description of the content in the my-all-in-one-project-platform-docker (typically named ) sub-project. This sub-project contains the resources required to define a custom Docker image with the Content Services Repository and the customization module my-all-in-one-project-platform installed.
Below is a description of the content in the my-all-in-one-project-share (typically named ) sub-project. This sub-project contains the source code entirely dedicated to the customizing the Alfresco Share client.
Below is a description of the content in the my-all-in-one-project-share-docker (typically named ) sub-project. This sub-project contains the resources required to define a custom Docker image with the Alfresco Share Client and the customization module my-all-in-one-project-share installed.
Below is a description of the content in the my-all-in-one-project-integration-tests (typically named ) sub-project. This sub-project contains all the source code and resources needed to run the integration tests.
This integration test verifies the existence of the DemoComponent component deployed in the Content Services instance. You can find the definition of the DemoComponent as a custom component of a project created with the All-In-One archetype. For more details, see the class definition inPROJECT_ARTEFACTID-platform/src/main/java/com/example/platformsample/DemoComponent.java.
This is due to an issue with the component used by HotSwapAgent to notify the changes in the compiled class files. HotSwapAgent uses the class WatcherNIO2.java to watch for the changes in the extraClasspath folder. That class is based on the Java class WatchDir.java that, in Linux systems, is implemented using inotify. It seems that inotify is not working properlywith mounted volumes over Docker Toolbox (which internally uses VirtualBox).
A must-have book for every Java programmer and Java aspirant, Effective Java makes up for an excellent complementary read with other Java books or learning material.
