Can not you modify procedure yo use OUT parameters? Kind of
<parameterMap id="languageLookupMap" class="java.util.HashMap">
<parameter javaType="java.lang.String" mode="IN" jdbcType="VARCHAR"
property="from_text"/>
<parameter javaType="java.lang.String" mode="IN" jdbcType="VARCHAR"
property="language"/>
<parameter javaType="java.lang.String" mode="INOUT" jdbcType="VARCHAR"
property="to_text"/>
</parameterMap>
<procedure id="languageLookup" parameterMap="languageLookupMap">
{call language_lookup @from_text = ?, @language = ?, @to_text = ?}
</procedure>
