Syntax error in Java persistence language

Question

I wrote this simple program to use Java Persistence Query
public static void main(String[] args) {
test test = new test();
EntityManagerFactory emf = Persistence.createEntityManagerFactory("SVGTopLink");
EntityManager em = emf.createEntityManager();
String sql_text = "SELECT NEW " +
"joinBasicShapes(c.chartName,c.height,c.width,sh.idShape,sh.points,sh.r1,sh.rx,sh.ry,sh.typeName,sh.widthR,sh.x1,sh.x2,sh.y1,sh.y2) "+
"FROM SvgCharts c JOIN BasicShapes sh ON c.id_chart=sh.id_chart WHERE c.id_chart = 1";
Query query = em.createQuery(sql_text);
List lista = query.getResultList();
Iterator it = lista.iterator();
for(int i=0;it.hasNext();it.next()) {
System.out.println("---");
em.close();
emf.close();
But EntityManager doesn't like the query. Do you have any ideea?

Can you tel me what means DOT - this is what is supposed to wait - in from clause eg FROM SvgCharts c JOIN BasicShapes sh .
Many thanks,

Answer 1

I have these entities ,
public class SvgCharts implements Serializable {
@Id
@Column(name="ID_CHART", nullable = false)
private Long idChart;
@OneToMany(mappedBy = "svgCharts")
private List<BasicShapes> basicShapesList;
public class BasicShapes implements Serializable {
@ManyToOne
@JoinColumn(name = "ID_CHART", referencedColumnName = "ID_CHART")
private SvgCharts svgCharts;
ID_CHART is the PK in svgCharts and FK in basicShapes
I have write this code
String sql_text = "SELECT o FROM SvgCharts charts JOIN charts.ID_CHART shapes WHERE charts.ID_CHART = 1";
Query query = em.createQuery(sql_text);
List lista = query.getResultList();
But I get the following error ;
Exception Description: Error compiling the query [SELECT o FROM SvgCharts charts JOIN charts.ID_CHART shapes WHERE charts.ID_CHART = 1], line 1, column 44: unknown state or association field [ID_CHART] of class [svgtoplink3.SvgCharts].
What do you think? I use JDeveloper 11TP4 for this
Thans in advance,
