No worries mate. You don't need to modify openjpa (in this case),
it's designed to allow you to plug in your own classes, which live
inside your own jar files, by specifying your plug-ins in the
properties. Other than my DBDictionaries (I have plugged in separate
DBDic for Oracle, Postgres, etc.) I have some other classes plugged in
to kodo.FilterListeners and kodo.AggregateListeners and so on... So
far I haven't needed to modify the openjpa distribution. Anyway, good
luck with it.
cheers!

Hi Drew, thanks for your suggestion, I had thought of that but didn't
want to go modifying weblogic's distribution of openjpa.

Subject: Re: java.util.Data mapping to abstime (deprecated) in
postgres
Hi Daniel. I also had your problem and fixed it by implementing my
own DBDictionary (subclass of PostgresDictionary) and plugging it in
using the kodo.jdbc.DBDictionary configuration setting... Below is
an
sample of my dbdictionary which might be helpful...
cheers!
.droo.
public class MyPostgresDictionary extends PostgresDictionary
{
private static final String TIMESTAMPTYPENAME = "timestamp";
/**
* return the Database type for the given Java type.
* When using postgres 8, map java.util.Date type to postgres
TIMESTAMP column type,
* instead of the Kodo PostgresDictionary default, which is
ABSTIME. ABSTIME cannot
* represent dates beyond 19/01/2038. if the type parameter does
not specify a a Date,
* then the default PostgresDictionary behaviour applies.
*/
@Override
public String getTypeName(int type)
{
if (type == Types.TIMESTAMP)
{
return TIMESTAMPTYPENAME;
}
else
{
return super.getTypeName(type);
}
}
//...
}

Hi all,
I am using BEA Weblogic 10, which implements persistence by using
kodo
and openjpa.
I have set this up to persist to a Postgres 8.3 Database.
I have a java.util.Date that I want as a column in a table.
When I run the mapping tool, it maps the java.util.Data datatype to
Postgres datatype "abstime". However, this datatype is deprecated,
and
should be mapping to "timestamp without time zone" instead.
Has anyone had any success in mapping this properly?
Perhaps I should raise a bug against openjpa?
Thanks
