soft 1.6 java problem-english

Hi to all the members.
I have just upgraded my sgh s100 to 1,6 ver with me everything works fine i can even download polyphonic ringtones via wap via gprs and they are saved what was previously impossible for me.The only problem which is still unsolved is java.Every time i try to download any java application the same message appears"jad file damaged" and then wheni try to install it phone resets gprs connection(csd too) and starts connecting again but nothin hapens.I tried many wap sites without any result.I want to mention that my gsm provider supports 15 kb limit on the downloads file via wap which is quite good.Wap over gprs and csd works perfect.
Is there any solution for this.Any public gateway i can use(for gprs connection).
P.s Downloading Java is not possible via gprs nor csd
Please do not give me a link to this forum because i already translated many of them i didn't find anything that helps me.
Thanks for help
Regards Tom.
