I have already implemented all java beans with SqlArrayAdapter,IntArray and
IntArrayTypeHandler..But iam still facing the same problem....Actually i had
implemented my project using spring mvc with iBatis..I think spring MVC
problem...
I again mention that particular error as follows....Any body have any idea
to solve that problem... Please sent reply immediately...
INFO [org.springframework.beans.factory.xml.XmlBeanDefinitionReader] -
<Loading XML bean definitions from class path resource
[org/springframework/jdbc/support/sql-error-codes.xml]>
INFO [org.springframework.jdbc.support.SQLErrorCodesFactory] -
<SQLErrorCodes loaded: [DB2, Derby, H2, HSQL, Informix, MS-SQL, MySQL,
Oracle, PostgreSQL, Sybase]>
