Hi,
Updating an Entity in the @prepersist or @preupdate method is permitted.
This was previously discussed on the dev forum [1] with the JIRA [2]
resolved for the 1.2.x, 1.3.x, and trunk branches.  Are you finding that
this support is not working for you, or were you just asking the question?

These type of updates to the Entity will affect the sql that is generated.
But, I agree with Jody that OpenJPA does not allow direct manipulation of
the generated sql.

can't you set the attibute "active = false" and then use normal 
persistence instead of delete?

During user search you can set "active = true" in the search pattern...

I misunderstand?

for example, when I delete User entity I need to set active = false , instead
of actually deleting the record.

I don't think that the SQL generated by OpenJPA entitymanager operations
can be directly modified.  What sort of modifications are you looking
for?  There might be supported function to direct OpenJPA to create the
sort of SQL that you are looking for.
