database connection error property, error, null, java

amy

In Spring when I use datasource as -

lt;bean id=quot;dataSourcequot; class=quot;org..jndi.JndiObjectFactoryB  eanquot; destroy-method=quot;closequot;gt;
lt;property name=quot;jndiNamequot; value=quot;java:SmartLMSDBquot; /gt;   lt;property name=quot;resourceRefquot; value=quot;truequot; /gt;        
lt;/beangt;
it gives me connection=null for first hit to database at second hit it works fine.

And, when I use datasource as -

lt;bean id=quot;dataSourcequot; class=quot;org..jdbc.datasource.DriverM  anagerDataSourcequot; gt;
lt;property name=quot;driverClassNamequot; value=quot;com.mysql.jdbc.Driverquot;/gt;
lt;property name=quot;uclquot; value=quot;jdbc:mysql--10.20.10.7/SmartLMSquot;/gt;
lt;property name=quot;usernamequot; value=quot;SmartLMSquot;/gt;
lt;property name=quot;passwordquot; value=quot;SmartLMSquot;/gt;
lt;/beangt;

there is no problem.
