Problem: org.springframework.jdbc.UncategorizedSQLException: Error setting null parameter. Most JDBC drivers require that the JdbcType must be specified for all nullable parameters.
Cause: The JdbcType property is not set in the XML mapper.
Solution: Specify jdbcType of the parameter in the mapper.
<select id="selectByYear" parameterType="map" resultMap="BaseResultMap">
SELECT *
FROM tbl_calendar
WHERE year=#{year,jdbcType=DECIMAL}
</select>
Problem: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for
Cause: The same namespace is used in 2 different mappers.
Solution: Change the namespace in one of the mappers.
<?mapper namespace="com.blogspot.adaprognotebook.dao.mybatis.CompanyMapper" >
Problem: When generating the iMbatis mapping files in Eclipse, "Fail to generate mapper files: Exception getting JDBC Driver" error is encountered.

Cause: Eclipse cannot find the JDBC library file.
Solution: Add <classPathEntry> to the "generatorConfig.xml" to define the class path of the library file.
generatorConfig.xml
