Need help to run java apps on openmoko

Hi, I am new to openmoko. I want to run one of my java based GUI application on openmoko. But when I tried to check for the java support on the newly brought model, I found there is no java utility pre installed (Any JVM for running java apps). So can you guide me how can I set up my openmoko to run java applications on it? Is there any extra package I need to install? Please guide me, without finding it I can't proceed. Your valuable suggestion will be greatly helpful for me. Thank you Regards Girish +91 99867 64809
