I did not define any new sql type for vector. Vector is java.lang.Object. I
don't have any problems with vector but with array which vector class
contains. I can read the Vector object from the database, but the vector
size is 0 and data array of vector is empty.
I try not to use any sql statements, but only CMP. I did some research and
my major problem is how to store array of any type in the database with CMP.

what sql type are you using? blob?
in general I wouldnt serialize a vector to a data table. I would populate a
vector (actually probably an array list... ) from sql results.
