Hi all

At work today I downloaded and ran the emsim.jar program and on an XP 
machine it ran perfectly. What I don't understand is how, when Java was 
created to be platform independent, does it crash and burn on Debian where 
I have (AFAIK) all of the relevant program libraries, but on XP it does 
what it is supposed to do.

How do I go about checking out what libraries this Java program needs and 
which of those my Debian installation can satisfy?

TIA

Hi Andy,
It looks like the GNU gcj java support does not do SWING?  You have a couple of options:  investigate SWING support for gcj ( I do not know if it is supported or not ) , or install the sun java package via apt.  Make sure if you install the sun java you remember update-alternatives to select the sun java javac jar etcetera :)

I have the sun java for my J2ME playtime project and it works fine.

Hi Linc

Thanks for coming back to me on this. I ran apt-cache search sun and this was the output:

sun-java5-bin - Sun Java(TM) Runtime Environment (JRE) 5.0 (architecture dependent files)
sun-java5-demo - Sun Java(TM) Development Kit (JDK) 5.0 demos and examples
sun-java5-doc - Sun JDK(TM) Documention -- integration installer
sun-java5-fonts - Lucida TrueType fonts (from the Sun JRE)
sun-java5-jdk - Sun Java(TM) Development Kit (JDK) 5.0
sun-java5-jre - Sun Java(TM) Runtime Environment (JRE) 5.0 (architecture independent files)
sun-java5-plugin - The Java(TM) Plug-in, Java SE 5.0

sun-java6-bin - Sun Java(TM) Runtime Environment (JRE) 6 (architecture dependent files)
sun-java6-demo - Sun Java(TM) Development Kit (JDK) 6 demos and examples
sun-java6-doc - Sun JDK(TM) Documention -- integration installer

sun-java6-jdk - Sun Java(TM) Development Kit (JDK) 6

sun-java6-plugin - The Java(TM) Plug-in, Java SE 6
sun-java6-source - Sun Java(TM) Development Kit (JDK) 6 source files

I recognise that there are two groups java5 and java6. My inclination is to go for java6, but are there specific packages required that you have in mind wrt your recommendation?

Cheers

Andy
