Actually you can, but it is a pain and inefficient because
you do it on every field access.
public abstract MyEntityBean extends EntityBean
{
public abstract int getField1Internal();
public abstract void setField1Internal(int value);
public int getField1External()
{
return getField1Internal();
}
public void setField1External(int value)
{
if (value != getField1Internal())
doModified(); // Here is your hook
setField1Internal(value);
}
public abstract Date getLastModified();
public abstract void setLastModified(Date date);
public void doModified()
{
setLastModified(System.currentTimeMillis());
}
}
You expose get/setField1External on the remote/local interface
and use field1Internal in the cmp mapping.
Writing your own xdoclet template might help with the boilerplate.
This is an alternate mechanism that is jboss specific:
