What's going on with Mac version?

That's a question we have got a lot of times. It was answered here and in different forums, describing why it take some time to release Mac version so I'm not going to write the reasons again. Today I'm going to show you something behind the scene. We are running Scrum process while developing Java ME SDK. Next two pictures were taken at the end of our latest sprint.

The first pictures shows our office board with table of stories and their tasks. As you can see we finished all tasks.

Taskboard

The second picture is more interesting. It shows burndown chart, which is a is graphical representation of work left to do versus time. The green line represents the ideal burndown. You can see that our progress was under the ideal line. It means that we worked faster and finished our tasks sooner than we expected when planning the sprint. Especially in the beginning the progress was quite rapid so in the middle of the sprint we added a few extra stories and we achieved all of them.

Burn down chart

That's what is happening in our team and hopefully answers the title question. Java ME SDK for Mac is in progress and it goes well ... stay tuned – coming soon to a computer near you!

1 update found

Have you started Java ME SDK 3.0 and see a small icon in the bottom right corner?

Update Notification

It appeared there about a month ago and some of you maybe asked what it means. The icon notifies you about available updates for Java ME SDK. This is a new feature in 3.0 release and allows delivery of updates faster than regular releases.

It is very easy and simple to install new updates, just click on the icon and follow instructions.

This first update contains updates of BD-J libraries from HDcookbook project and a few small fixes in Blu-ray development support. During the updating process you can see a message that plugins are signed but not trusted. You can trust them. This issue is also solved in the update and if you install the update this warning will not appear again in the future for next updates.

VisualVM understands Java ME Profiler Snapshot

Java ME SDK 3.0 supports offline profiling. Data is collected during the emulation session. After you close the emulator a profiler data snapshot is written to a .prof file which you can load and view in the SDK.

Since last Friday it is possible to load and view Java ME SDK profiler file also in VisualVM 1.1. VisualVM is a tool to monitor and troubleshoot Java applications. For more information about VisualVM visit its homepage.

How to view Java ME SDK profiler file in VisualVM? It's easy. Everything you have to do is to install Java ME Profiler Snapshot Viewer module from VisualVM update center.

  1. Start VisualVM.
  2. Open Plugins manager from Tools->Plugins menu.

    Tools->Plugins menu

  3. In Available Plugins tab select Java ME Profiler Snapshot Viewer and click Install button.

    VisualVM Update Center


When the module is installed, new action Import Java ME SDK Snapshot... is added to the application File menu.

Import Java ME SDK Snapshot...

Java ME SDK profiler file can be opened and shown in VisualVM by this action. Default location of Java ME SDK profiler file is <user_home>/javame-sdk/3.0/work/<device_number>/data.prof.

Future Directions

 

Just a day after Java ME SDK 3.0 release we decided to have the first meeting about features for next Java ME SDK version. It was a nice sunny day in Prague and we were sitting on the grass in front of our building to get fresh ideas on the fresh air. We put together long list of enhancements and new features but we would also like to know your opinion. Do you miss some feature? Do you think something should be improved? Share your mind with us, we will very appreciate it.
