Dear all,

I am facing a null pointer exception while trying to build a Spring JDBC application.

The code that calls the Dao Interface is :



The code for retrieveNodeLocationCount is defined in the Dao class file of XRefUtilityDao.java as below:
public int retrieveNodeLocationCount(String nodeLocation);


The implementation is defined in this file : XRefUtilityDaoImpl.java as :




For some reason the the execution doesn't reach this portion of code called. Every time I pass the parameters to this method in


It returns a Null Pointer exception.

Is it true that the service poid contains tmm_streamyx?--->false


I am still new at this Spring Jdbc, I was wondering why this problem cropped up. Maybe I missed something. Thank you.

Hi,

from your posted code I was not able to see what is the statment in MCMBSimplyForFun.java:180 line.
Basically, the getJdbcTemplate.queryForInt doesn't throw NullPointerException.
Are you sure that getJdbcTemplate is not null it self, you can check it, if not then give a try to execute a very simple query which is 100% should run (e.g. without any paramter)

Regards,
Csaba
