NullPointerException coming from StandardDaoManager

Mon, 25 Apr 2005 06:24:03 -0700

Has anyone seen this issue?

 

I am receiving a NullPointerException within the [com.ibatis.dao.engine.impl.]StandardDaoManager class when It tries to invoke getTransaction() on my DAO.  The

exception is occuring below: (source is from StandardDaoManager.java)

 

  public DaoTransaction getTransaction(Dao dao) {

    DaoImpl impl = (DaoImpl) daoImplMap.get(dao);

    return impl.getDaoContext().getTransaction();  <-- NullPointerException

  }

 

In this particular case, I do not have any required transactions setup for this DAO; just a simple select (like 'select count(1) from dual'...)    I have checked my DaoConfig object - it appears to be fine.  I'm trying to figure out if it has to do with my sqlMap declaration in my sql-map-config.xml file, or is that my DaoConfig loaded, but incorrectly, or ....

 

Does anyone have any pointers on this?

 

Thanks.
