I am executing a simple select HQL query

from CertObjRel where certificatePrimary in (:certificatePrimaryList)
where certificatePrimaryList is a java arrayList of certificatePrimary

CertificatePrimary class:
class CertificatePrimary implements Serializable{
//private int primaryId;
private String certificateId;
private Short trsSequenceNbr;

public String getCertificateId() {
return certificateId;
}

public Short getTrsSequenceNbr() {
return trsSequenceNbr;
}

public void setCertificateId(String certificateId) {
this.certificateId = certificateId;
}

public void setTrsSequenceNbr(Short trsSequenceNbr) {
this.trsSequenceNbr = trsSequenceNbr; }
}

CertObjRelMapping contains CertificatePrimary as component

CertObjRel.hbm.xml

<component name="certificatePrimary" class="com.csc.exceed.certificate.domain.CertificatePrimary">
<property name="certificateId" type="java.lang.String" column="CERT_ID" length="36" not-null="true"/>
<property name="trsSequenceNbr" type="java.lang.Short" column="CERT_TRS_SEQ_NBR" />
</component>

I am getting the following error

DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=(;RT_TRS_SEQ_NBR) in (;<values>, DRIVER=3.50.152 )
