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.

Moin is just another way to say good bye
