Java questions
« on: July 17, 2004, 08:48:44 am »
I am thinking of installing the pdaXrom in my c860 but what i really need is to be able to run (and maybe compile) java programs. I know there is a blackdown java version for this ROM but i don't know what are the differences between this VM and the sun personal profile VM and the jeode vm. Has anyone tried to run a java program in the X11 ROM and compare the times with the jeode or sun vm's?. Does this zaurus-blackdown java has swing implemented? I have seen that there is a jave sable vm for the debian zaurus version (www.pocketworkstation.com) Is it better than the blackdown? are there plans to port this vm to the X11?

Thanks

Hi,
Jeode and PP4Zaurus only work with QT based roms. So you can not develope GUI-programms with them under the pdaXrom. There are other alternatives. One is jamvm, which comes with the gnu classes. If you are able to compile them for the pdaXrom, you can use them with the pdaXrom. I tried it earlier this year and was able to compile jamvm directly on the zaurus. But I was not able to compile these gnu classes on the top of jamvm. Perhaps it is now much easier. You will find jamvm at sourceforge.

Hi thanks flens for the information, I didn't know about this jamvm. I have tried the sable vm (which has some swing implemented) in the debian-linux for the zaurus but for what I've seen, it's slower than the pp4zaurus or jeode vm. Do you know if there is any (future) project (supported by the pdaXrom team) for building a decent java vm (perhaps this javavm) optimized for the X11 ROM?.

Thanks

Hi,
Please have a look at
http://faqs.adorphuye.com/index.php?sid=20...igen&rubrik=008

Here you can find mire informations about java vm's, which run on the Zaurus. Perhaps Blackdown is an alternative. I didn't try it.

Someone has put together a Blackdown JVM ipk that will install and run on the pdaXrom. I installed it and it works perfectly. I can even run fullblown swing apps, which none of the other "micro" JVMs support!

You will find everything you need here:

Hi,

Good to know that someone has tested a "real" swing app that it actually works!.  I'll have to try the pdaXROM and compare the execution times with this vm and the jeode and pp4zaurus ones.

Thanks to all for the information.
