The revised specification removes support for columnmetadata. This makes the Nullable property retrieval exception obsolete. |
This code: <li><b>Nullable:</b> <c:out value='${columnMetaData.nullable}'/><br/></li> Causes the following exception: javax.servlet.ServletException: Unable to find a value for "nullable" in object of
