• Can java collection be fixed?

  If you're curious, attach VisualVM and watch the RAM usage graph. You'll notice that Java performs garbage collections long before reaching allocating the maximum amount of RAM allocated, and you can't even feel any performance issue in-game. Source: about 1 year ago

• Items won't drop when either mined or dropped from inventory and new chunks won't load.

  Hangs and deadlocks are significantly harder to debug. A first step is taking a thread dump so you can see what each thread in the JVM is currently trying to do. I like VisualVM for this, you can also use the command-line tools jps -l (to list all Java PIDs) and jstack for taking a thread dump. Source: about 1 year ago

• Top metrics for Elasticsearch monitoring with Prometheus

  The Java VisualVM project is an advanced dashboard for Memory and CPU monitoring. It features advanced resource visualization, as well as process and thread utilization. - Source: dev.to / about 1 year ago

• Anybody know what causes this? Entities simply going idle, can't eat, fps is still high, can break blocks etc . I have a gtx 1660 ryzen 2600 and 16gb ram. So my pc isn't bad. I allocated 8gb of ram. Doesn't happen all the time . Happening on my modpack with 200 mods

  This sounds like a server thread freeze/deadlock/crash or something. I think I would start debugging this using a tool like VisualVM; attach it to the game, wait for the hang, take a thread dump, and check what the server thread is up to. Source: about 1 year ago

• Why use javafx

  Just wanted to chip in to say that /u/UtilFunction is correct. The proper way to measure memory consumption of any Java application independent of which garbage collector is used is to perform a heap dump (which automatically forces a complete garbage collection). I like to use VisualVM for that. Source: about 1 year ago

• Spring Boot Monitoring with Open-Source Tools

  Manual instrumentation allows you to define your Spans within the code itself rather than relying on automatic instrumentation finding the entry point for a trace. Manual instrumentation is especially helpful for applications that don’t use an application server such as Tomcat, JBoss, or Jetty. - Source: dev.to / 6 months ago

• Issue with chatgpy

  99% is a huge exaggeration. Two essential deployment tools off the top of my head: Https://tomcat.apache.org/ Https://docs.jboss.org/author/display/AS71/Developer%20Guide.html. Source: about 1 year ago

• 7 years with Vaadin in production. Do we still enjoy it?

  Do we still enjoy it? We are running many Vaadin apps in production since that first one. If there are not any specific requirements we use a “modular monolith” concept, which fits our stack best. We pack applications as WAR and deploy them under Apache Tomcat. And yes, we enjoy the development process. It’s very straightforward and Vaadin and SpringBoot fit together well. - Source: dev.to / over 1 year ago

• TIBCO Jaspersoft Studio tutorial: Creating templates and integration with JasperReports Server

  JasperReports Server Community requires a Java application server and a database to create a repository in order to work properly. After downloading JRS, the installation process can install Tomcat server and PostgreSQL database automatically for us and the services will run depending on the Jasper server. It's also possible to connect JRS to services already installed on the server. Moreover, while the free... - Source: dev.to / over 1 year ago

• I wish to learn web development with java and while configuring apache tomcat 10.0.26 into Eclipse, I encountered this problem. Can anyone help me? Thank you.

  Don't use an installed copy of Tomcat. The layout can be different than expected and permission problems can appear at the worst time. For one, it needs to be able to write to that conf directory. Download a non-platform-specific "core" zip file from tomcat.apache.org instead. Source: over 1 year ago
