title: Is using external DAO jar/library of MyBatis possible?
body: <p>I want to make jar that consists of dao, domain(java class),mapper(xml) and mybatis-config.xml. This way, several projects can include the jar avoiding duplicated classes among the projects.</p>
  
  <p>I made the jar but got following error.</p>
  
  <p>It works fine when the classes, xml files are in the spring project instead of external jar.</p>

  <p>The spring config file is as follow.</p>
  
  <pre><code>    &lt;bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"
          p:dataSource-ref="ca-ds" p:mapperLocations="classpath:/com/test/ca/mapper/*mapper.xml"
