jasper查询中的参数映射

Question

这是我在jasper.jrxml中的查询：

<queryString>
        <![CDATA[SELECT c.id,
    b.nom_beneficier,
    c.date_saisie,
    cat.designation,
    c.montant_brut,
    c.montant_rs,
    c.net_rs,
    id_exercice
    FROM 
    crs_certificat c,
    crs_beneficier b,
    crs_categorie_taux cat
    WHERE 
     c.id_beneficier = b.id 
     AND c.categorie = cat.id 
     AND id_exercice = //I want to pass a parameter here
     AND c.delete_stat = 0]]>
    </queryString>

如何在此查询中加入参数并随时调用它？

修改
这是我声明我的参数但jasper无法看到它的地方：

<subDataset name="tableDataset" uuid="7a7abe40-c5fa-40c9-bc37-a573ee7d748a">
        <property name="com.jaspersoft.studio.data.defaultdataadapter" value="New Data Adapter "/>
        <parameter name="exercice" class="java.lang.Integer"/>
        <queryString>
            <![CDATA[SELECT c.id, nom_beneficier, date_saisie, designation, montant_brut, montant_rs, net_rs
FROM crs_certificat c, crs_beneficier b, crs_categorie_taux cat
WHERE id_beneficier = b.id and categorie = cat.id AND id_exercice = $P{exercice}]]>
        </queryString>
        <field name="id" class="java.lang.Integer"/>
        <field name="nom_beneficier" class="java.lang.String"/>
        <field name="date_saisie" class="java.sql.Date"/>
        <field name="designation" class="java.lang.String"/>
        <field name="montant_brut" class="java.lang.Double"/>
        <field name="montant_rs" class="java.lang.Double"/>
        <field name="net_rs" class="java.lang.Double"/>
    </subDataset>
