And below are my sql statement.

    <select id="select_TB_OC_USER_BADGE_INFO_001" parameterClass="TB_OC_USER_BADGE_INFO_VO" resultClass="TB_OC_USER_BADGE_INFO_VO">
        <![CDATA[
            SELECT
                    BADGE_MC,
                    BADGE_WB
                FROM
                    TB_OC_USER_BADGE_INFO
                WHERE
                    USER_ID = #USER_ID#
                AND
                    COMPANY_CODE = #COMPANY_CODE#
        ]]>
    </select>

Belows are TB_OC_USER_BADGE_INFO_VO. Didn't bring getter and setter.

public class TB_OC_USER_BADGE_INFO_VO {

    private String USER_ID;
    private String COMPANY_CODE;
    private String TYPE;
    private int BADGE_MC;
    private int BADGE_WB; }
Solution

  • The problem was firewall. The firewall had blocked java to access to database on other computer. When permitted the access, my program started working.
