Problems to update byte value in a table informix

[Anonymous]

I need help ... I have to update a table with a string of type byte. Paste the string in the TMAP by the cast: Byte.valueOf (dg1651dv161sd51 ..."), but when I try to upgrade gives the following error:
Exception in component tMap_5
java.lang.NumberFormatException: For input string: "504b0304140002000800074f5a3d75465ac3b ....
The field of the table that I update is byte, so realizao cast.
I hope I can teach. Thanks.

Hello
There exist some chars such 'a' ,'b' in these string "504b0304140002000800074f5a3d75465ac3b ....", you must remove these rows or do some processing before convert it to byte using Byte.valueOf(String s)
Best regards
