JDBC driver does not accept good md5 passwords

[Adam Radlowski <adamr@xxxxxxxxxxxxxxxxxxxxx>]

I'm using very often OpenOffice to administrate databases (It has 
options, wchich are not present in pgadmin3).
If I use JDBC connection and server don't requiers md5 passwords, I can 
edit and administrate the databases/tables via OpenOffice and JDBC. I 
can only read the tables. When server requiers md5 passwords I can't. Of 
course, I want to have possibility to edit tables via OpenOffice :-). 
Has anybody any idea, how to do this ?
I'm using "postgresql-8.2-504.jdbc3.jar" and "jre1.5.0_06". Server 8.0.7 
compiled/using on FC3 or binary installation 8.0.6 on Win2003. I've 
tried older *.jar version with this same result. OpenOffice 2.0.3 or 1.4.1.
Greetings
