Hi Dekaa,
can you check which other types (beside of java.lang.Object) are available for the input field type in the lower half of the adapter service?
Please check if you have latest Fixes for JDBC Adapter applied, there are sometimes issues solved there in relation to SPs.
You might want to have a look at the JDBC Adapter Users Guide if there is a hint about arrays.
Regards,
Holger
