Impossible to tell without you showing your class. Protected methods are no problem for hibernate.

basically I have parent clas called AccurateDate:

public class AccurateDate implements Serializable, Cloneable {

private Timestamp timestamp;

private int nanoseconds = -1;

{some more code here...}

protected void setTimestamp(Timestamp timestamp) {
if (timestamp != null) {
this.timestamp = (Timestamp) timestamp.clone();
updateTimestampNanos();
}
else
{
this.timestamp = null;
}
}

protected Timestamp getTimestamp() {
Timestamp returnedTimestamp = this.getDate();
if (!DBMS_SUPPORTS_MILLISECONDS) {
returnedTimestamp.setNanos(0);
}
return returnedTimestamp;
}

{similar accessor for the nanosec which is proetcted}


Then I have another class which is a subclass of this and this is what I'm trying to persist, here is the code:


public class PartialDate extends AccurateDate implements Serializable, Cloneable {
private PrecisionCode precision;

protected char getPrecisionChar() {
return precision.getPrecision();
}


protected void setPrecisionChar(char precision) {
this.precision = PrecisionCode.valueOf(precision);
}
}


here is my mapping for this: -- the partial date will be a component for a persistable class

<component name="dateOfBirth" class="com.orchestral.index.common.data.date.PartialDate">

<property name="timestamp" column="dateOfBirth" />
<property name="precisionChar" column="dateOfBirthPrecision" />
<property name="nanoseconds" column="dateOfBirthNanoseconds" />

</component>


The problem that I'm having is everytime I try to persist this class, Hibernate throws an exception that says it couldn't find the property called timestamp.

If I try to change the accessor methods to public, then it works without any problems -- so i guess my question is I thought hibernate supports public, protected or even private accessor methods?

Hm, I wonder why this should not work ... are you running under some kind of SecurityManager restrictions? Sure you made no typos?

Yep, I'm sure I haven't made any typo errors as I've checked it many times just to be sure it's not something silly like that. I am not aware of any securityManager that will cause this problem. Also, the things is if I cahnge the accessor methods into public then I don't get any errors. Some other team in our company has been using the PartialDate class in their project and the weired thing is they can get it to persist using the same mapping files as the one I'm using.

I've finally found out what's causing the problem. It just so happens that we are using an obfuscator for the java classes and the protected methods are being changed into some arbitrary method name, in which case this is the reason that hibernate cannot find the propected methods.
