If you are using jConnect with Adaptive Server on HP, the server’s default character set cannot be roman8. There is no corresponding Java character set converter for roman8, and jConnect will be unable to connect to the Adaptive Server.
Workaround: Set the client application character set to iso_1. The character mappings for iso_1 and roman8 character sets are similar, although they are not identical in all cases. Therefore, some character conversions may fail. When using this approach, make sure the client application catches any character set conversion exceptions.
