複合キーを持つ連想テーブルがあります。いくつかの値（複合キー）に基づいて選択する名前付きクエリを実行しようとしています。

コードは次のようになります。

@Entity
@NamedQueries({
@NamedQuery(name = "MW.findAll", query = "SELECT mw FROM MemberWorkout mw"),
@NamedQuery(name = "MW.find1", query = "SELECT mw FROM MemberWorkout mw WHERE mw.SocialSecurity LIKE :SocialSecurity"), })
@Table(name = "MemberWorkout")
public class MemberWorkout implements Serializable {

private Member member;
private Workout workout;
private String date;
private MWId mwId;

@EmbeddedId
public MWId getId() {
    return mwId;
}

public void setId(MWId mwId) {
    this.mwId = mwId;
}
....
@ManyToOne
@JoinColumn(name = "SocialSecurity", insertable = false, updatable = false)
public Member getMember() {
    return member;
}

public void setMember(Member member) {
    this.member = member;
}

これは、これをデプロイしてサーバー（JBOSS）を起動したときに発生する最初のエラーです。

問題を正しく理解していれば、は埋め込み可能なSocialSecurityフィールドです。MWIdクエリを使用してアクセスする場合は、次のように埋め込みIDを介してアクセスする必要があります。

SELECT mw FROM MemberWorkout mw WHERE mw.id.SocialSecurity...

あなたのコードのように、プロパティ名は大文字になっていると思います。そうでない場合は、適切な名前に置き換えてください。

プロパティアクセスを使用していることに注意してください。つまり、アクセサメソッドには注釈が付けられているため、JavaBean標準に従ってクエリでプロパティに名前を付ける必要があります（getId()つまり、HQLとJPQLはプロパティにとしてアクセスしますid）。フィールドに注釈を付ける場合は、クエリをに変更する必要がありますmwId。
