      Hello, I responding to a Vaadin post you made a while ago.

      „Currently I’m using Spring Tools Suite + Maven + JRebel … and it’s so easy to develop a Vaadin app … I love it emoticon“

      I am a basic JSF web app developer and am following the exact same footsteps are you are into Spring and Vaadin.

      Currently, I am hoping to discover how to connect my JSF remote data to Vaadin Grid. Any suggestions greatly appreciated:

      Thank you.

        Hi, oh dear this is very old stuff 🙂 Currently I don’t use STS directly anymore and JSF is totally out of scope in my daily work 🙂 But I think if you want use Vaadin Grid in JSF directly you can given Vaadin 8 with „web-components“ a try or if you have a real Vaadin App running .. extract the „old jsf data“ code and provide a „service implementation“ in your app for that.

    Enable JMX Management for Hibernate EhCache 

    Have a look at

    • net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory.start(Settings, Properties)
    • net.sf.ehcache.hibernate.management.impl.ProviderMBeanRegistrationHelper.registerMBean(CacheManager, Properties)
    What we need is a system property „tc.active“ with value „true“
    🙂

    Bloxel with simple mining prototype 

    Last weeks I tried to make a better way to describe how a piece of our bloxel world is filled with content.

    Why … because bloxel have some memory problems with completely filled chunks (hills, underground) … so there was only a surface … no mining was possible  🙂

    In my first version all TerrainElement’s in a chunk stored with a simple ArrayList. So the TerrainLoader (height map based) initialize a chunk with some elements to build a surface. There is no underground information. I tried to fix this by creating ALL elements under the surface and storing them in the chunk … but then the memory usage was very high and the rendering very slow (actually we have no good culling implemented). I guess there is a better solution to describe the elements in a chunk. I tried the Octree.

    Imagine a 8x8x8 chunk filled with 8x8x7 dirt (underground) and 8x8x1 grass (surface). Then the chunk has 512 bloxels, most of them are the same material : dirt … so it’s better to merge same 1x1x1 bloxels into a bigger bloxel.

    Now I’m using a Octree to pack same elements for a chunk. This reduce memory and It’s faster to get the type of x,y,z bloxel from a chunk. After a change on the chunk (add or remove bloxels) the Octree needs an update.

    In the next blog I will go deeper into the technical details … for now 2 new screenshots … with a lot of sand under the surface 😀

    Progress splash screen in java with simulate mode 

    Today I will share a little piece of code … a splash screen with a progress bar feature.

    The splash screen support three modes:

    • Indeterminate – animated percentage of completion
    • Determinate – defined percentage of completion
    • Determinate + Simulation – define a FROM and TO percentage and the progress bar will run automatically  (done with the  autoProgressExecutor)

           }
         }
       });
     }
    }

        TimeUnit.SECONDS.sleep(2);
        splashScreen3.showProgress(90, 2);
        TimeUnit.SECONDS.sleep(2);

        final InputStream imageStream4 = ProgressSplashScreenTest.class.getResourceAsStream("splashscreen.jpg");
        final ProgressSplashScreen splashScreen4 = new ProgressSplashScreen(imageStream4, 1, 100);
        splashScreen4.showProgress(25, 1);
        TimeUnit.SECONDS.sleep(1);
        splashScreen4.showProgress(25, 75, 2);
        TimeUnit.SECONDS.sleep(2);
        splashScreen4.showProgress(90, 2);
        TimeUnit.SECONDS.sleep(2);
        splashScreen4.showProgress(100, 2);
        TimeUnit.SECONDS.sleep(2);
