hi this is srikanth pilli from india. actually my aim is to implement the TOUCH applications with jamvm-1.5.4 and classpath-0.98 on arm9 cortex processor(ar9) i.e pandaboard. when i am trying to run java application on arm9 TFT pannel (touch screen) , it shows the message like " [dynamic-linking native method:java.lang.VMObject.wait...internel]" and after that the next line it shows "fatal IO error 0(sucess) on xserver:0".

when i follow the linux forums , most of the people suggest that this message will get due the because of HEAP MEMORY problem. so one of the person suggest me that , to solve this memory problem he suggest to change the x-loader . and he mentioned the following URL
