using jboss 3.2.0RC1 I have found the following problem:
-- I have an entity bean B with container managed persistency.
-- It contains a field F of sql type OBJECT (a java class of my application), which is serialized when it is written on the corresponding database table.
-- I change an integer field I of this class object
-- Then I call the set method of bean B to store field F back to the database.
-- The database is not correctly updated because if we retrieve field F the value of I is not changed.
-- I have solved the problem using a clone of F before calling the set method of the bean B. The database is correctly updated that is if we retrieve F the value of I is changed.
-- It seems that in the first case the server does not recognize that the field F is changed when one of its fields has been changed and so it does not store it back to the database. With a clone of F, which is a different object, it assumes that F is changed.
-- In jbosscmp-jdbc file I have specified
-- In jboss.xml I have specified
<container-configuration extends="Standard CMP 2.x EntityBean">
<container-name>EntityBean Container Configuration</container-name>
Is this a known bug? Is it planned for new jboss 4 version?
