The entity bean wizard in MyEclipse by default puts the xdoclet tags needed to create a CMP at the top level. However, the only way to add CMP fields is just to manually add the getter/setter fields with the corresponding xdoclet tag:
/**
* @ejb.persistent-field
* @ejb.persistence
* column-name="fieldName"
* sql-type="VARCHAR"
*/
public abstract String getFieldName();
public abstract void setFieldName(String str);
