In case you are running CMP entity bean, update is done by generated persistency layer and you can perform it just be setting persistent properties (set...() methods) mapped to database table fileds.
for example, if I have a record in the table that has a primary key N, if I want to update this record with another one with the same value for primary key.....
...in this case I must generate the related entity bean (persistency layer) and use the set methods. Is this right? The record will be updated? <u>Is it the same like I write a record?</u> I don't worry if the record is present in the table(??)
Are you familiar with enitiy beanse? First you have to get reference to home interface (through JNDI), call one of find methods (or create for enitity creation), get reference to component interface of entity bean (or collection of it if it is multiple entities finder), and afterwards call one of setter ot getter(update on DB level is done implicitly).
