Hi everyone. I have OpenGinga running over Vmware Player, I've been
able to run the BBBxlet example and switch channels. But when I tried
to run my "HelloWorld" xlet( which I previously tested with xletView),
I got major minor error, so I would like to know how shoud I proceed
in order to succesufully compile my java source and run it in
OpenGinga. Thx in advance

Hi.
I fixed this by switching to version 1.4 of java. Anyway, I can´t see any graphics, seems mhp is no longer supported( at least for running; you can still compile mhp stuff in OpenGinga).

Hello,
MHP requires some APIs that are not present in Ginga, Then, if you use
some classes from HAVI or DAVIC, your application will not be able to
compile in OpenGinga, But, if you are using only javaTV stuff, you
should not have problems to compile them.
Regards,
Raoni

Hi Raoni.
Thx for your answer. In fact, my source( which uses some Havi classes) is able to compile in OpenGinga. The problem is on execution: program is loaded, writes to standard output but I don't see any graphics( in particular, it should show some HLabel).
Best Regards

In fact, I'm trying to run a simple HelloWorld xlet, showing a single Label, but I'm using this time Java-DTV( in a similar way as the BBBXlet eexample): My program is not able to show any graphic( I'm using form.setVisible() but it's being ignored, my form is not set visible). Basically, I'm making a simpler version of the BBBXlet example which comes with OpenGinga.
Until now, the only succesufull xlet I have ran is the BBBXlet example( I know for sure it's not a problem with compilation: I copy the source code from OpenGinga and compile it again, then copy the .class back to OpenGinga and it worked as expected). I suspect I'm missing some configuration issue. I thought it was something related with the apliccation id or the organization id in tmp/config.xml , but I changed this parameters for BBBXlet and it still ran.
If someone can shed some light in how to run a "visible" xlet in OpenGinga, I would be very grateful.
Greetings.

I was finally able to run my own aplications: what was happening is
that i was simply drawing outside my Form. Anyway, My ouput messages
were misleading, because many of the methods in Form and Label are not
yet implemented in OpenGinga Beta 1, one example: when you set your
Label text, this text is in fact shown in your Label, but when you use
the getText() method, you get null in return, cause this.text is not
actually updated. Similar things happen with Form.isVisible and other
methods, so you must not really rely on them unless, of course, you
modify the required sources.
Hope this info can help someone.
Regards.
