We'll chang the API of ProjX applications for some listeners. The changes are available in our nightly/weekly builds and in our repository. Please be sure to test your applications because generic listeners won't throw an exception at compile time, only at runtime.

Our Monitoring tool for JVx applications is very useful for application maintenance but also for application development. It safes time, problems and costs. The tool itself is a standalone JVx application and it connects to another JVx application which was configured with the monitoring plugin. It's not a hard job to configure a JVx application for monitoring, but it's boring.

We now have a really great VisionX AddOn which does all the boring work for you. It configures your applications for monitoring and makes it possible to monitor your applications during development time. It's very helpful to find bottlenecks or to do tuning before deployment

The plugin comes with an additional awesome Feature, which isn't available without the AddOn. It's the maintenance module. This module allows you to switch your application(s) in maintenance mode. You could use the maintenance mode to do manual database updates, config updates or simple health checks.

We have a short demo video which shows how it works:

The AddOn will be available in our Solution store, but not for free. The monitoring tool needs a separate license.

Our JVx headless UI (aka JVx.web) implementation is available as maven snapshot:

Don't forget the snapshot repository:

Our JVx mobile project is available as maven snapshot:

and only the API

Our JavaFX UI for JVx is available as maven snapshot:

or only JavaFX extensions

Our JVx online help system is available as maven artifact:

and as snapshot (weekly):

We're happy to announce that JVx 2.5.1 is available.

What's new?

• Push-light

  Our push support has nothing to do with Websockets. It's a technology independent solution for JVx. The Push-light mechanism is available on server-side and enables you to send objects from the server to the client. If you use a direct connection betwenn client and server, the objects wil be sent immediate (e.g. vaadin UI). If you use a serialized connection, the objects will be sent with next client call or alive check.

  The API is simple:

  SessionContext.publishCallBackResult("MESSAGE", "Please logout!");

  or, in a Thread

  final ICallBackBroker broker = SessionContext.getCurrentInstance().getCallBackBroker();

  Thread th = new Thread(new Runnable()
  {
      public void run()
      {
          try
          {
              int i = 0;

              while (isMessageLoopEnabled(i))
              {
                  Thread.sleep(200);
                 
                  broker.publish("MESSAGE", getMessage(i++));
              }
          }
          catch (InterruptedException ie)
          {
              //done
          }
      }
  });
  th.start();

  It's also possible to publish to all clients, via ICallBackBroker.

  The client code is short and simple:

  connection.addCallBackResultListener(new ICallBackResultListener()
  {
      public void callBackResult(CallBackResultEvent pEvent)
      {
          if ("MESSAGE".equals(pEvent.getInstruction()))
          {
              showMessage((String)pEvent.getObject());
          }
      }
  });

• H2 DB support

  We support H2 with a custom H2DBAccess. The auto detection works with URLs: jdbc:h2:.

• SQLite DB support

  We support SQLite with a custom SQLiteDBAccess. The auto detection works with URLs: jdbc:sqlite:.

• MySql limit support

  Read more...

• Life-cylcle object method inheritance
• Pie control
• Set individual cells of a table readonly
• Connection retries

  We try to re-send requests, if errors occur during transmission. This feature will be available for serialized connections only.

• Security improvements

  see Tickets: #1605, #1606, #630.

• Session validator

  We introduced ISessionValidator interface. It allows you to cancel the session after successful authentication. You don't need a custom security manager for this!
  Simply configure the validator in your config.xml:

  <lifecycle>
    <mastersession postAuthClass="com.sibvisions.apps.server.MySessionValidator">
  com.sibvisions.apps.demo.MySession
    </mastersession>
  </lifecycle>
• API changes

  ICellFormat got a Style attribute and the createCellFormat of IFactory got one more parameter.

The full changelog is available here.

This is a follow-up post for: Eclipse MARS with ANT and JRE 6 (story).

New Eclipse version, same problem. We have an updated ant plugin for you.
The plugin was created for:

Don't forget the -clean start (read the original article for more details).

Download the plugin from here. It works for us - no warranty!

The next JVx release will be version 2.5. It will be available by the end of this week (beginning of July). It's a really cool release because JVx got awesome new features. We had to change the API a little bit but it shouldn't be a problem for your existing applications.

What will be interesting?

The current update release of VisionX 2.3.235 is available for our customers or as trial.
It's a smaller update release with some nice features:

• VisionX listener

  It's now possible to get events of VisionX in you custom AddOns or Modules.

• Guides

  VisionX got Guides (Read more...). The feature is still in a test phase.

• Synonyms pointing to a view

  The Data Edit wizard supports synonyms pointing to a view. But be careful, because automatic metadata detection is limited in that case.

• Lib update

  All libs (JVx, ProjX, VaadinApps, ...) were updated to their latest versions.

The rest are fixes for smaller bugs (most are only relevant for developers):

• Support for BooleanDataType
• Help creation works if you didn't set a group label
• Designer view doesn't toggle the width while dragging
• Better variable naming for DBStorage types

Have fun with VisionX 2.3.235.
