Hi,
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

<read-ahead>
none
</read-ahead>
<list-cache-max>0</list-cache-max>
<fetch-size>0</fetch-size>


-- In jboss.xml I have specified
<container-configuration extends="Standard CMP 2.x EntityBean">
<container-name>EntityBean Container Configuration</container-name>
<commit-option>C</commit-option>
</container-configuration>




Is this a known bug? Is it planned for new jboss 4 version?


best regards
