Tried doing this.But the results are not accurate.

Property property = (Property)persistentClass.getProperty(propertyName);
((Column)property.getColumnIterator().next()).getLength();


System.out.print(persister.getPropertyColumnNames(propertyName)[0]);

I have following table structure:
TYPE_NAME VARCHAR2(200)
CREATION_DATE DATE
CREATED_BY VARCHAR2(200) Y
LAST_UPDATE_DATE DATE Y
LAST_UPDATED_BY VARCHAR2(200) Y
DISPLAY_NAME VARCHAR2(200) Y
ENABLED VARCHAR2(1) Y
DESCRIPTION VARCHAR2(4000) Y


The results I got is:

CREATED_BY Column length :::255 STRING
CREATION_DATE Column length :::255 TIMESTAMP
DESCRIPTION Column length :::255 STRING
DISPLAY_NAME Column length :::200 STRING
ENABLED Column length :::255 STRING
LAST_UPDATED_BY Column length :::255 STRING
LAST_UPDATE_DATE Column length :::255 TIMESTAMP
TYPE_NAME Column length :::200 STRING

Please advice

You can also use the JDBC meta data for that.
