[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - facing issues in persisting standalone application using hib
Hi I am new to this area and I am using hibernate3.2, hibernate-annotation3.2 and
hibernate-entitymanager3.2 for persisting a object in the database in a standalone
program i.e. plain java, but i am getting the following program when i run.
Please suggest any solution or if i am missing anything: exception is =:
[java] Exception in thread "main" java.lang.IllegalAccessError: tried to

Code is some thing like this:
/**
* AB generated by hbm2java
*/
@Entity
@Table(name="ABs"
,schema="Cat"
, uniqueConstraints = { }
)
public class ABs implements java.io.Serializable {
// Fields
private NId id;
private Cdates cdates;
// Constructors
/** default constructor */
public ABs() { }
/** full constructor */
public ABs(NId id, Cdates cdates) {
this.id = id;
this.cdates = cdates; }
// Property accessors
@EmbeddedId
@AttributeOverrides( {
@AttributeOverride(name="A",...))
@AttributeOverride(name="B", ...) ) } )
public NId getId() { return this.id; }
public void setId(NId id) { this.id = id; }
@ManyToOne(cascade={},
fetch=FetchType.LAZY)
@JoinColumn(name="A", unique=false, nullable=false, insertable=false,
updatable=false)
......
}
another class
/**
* NId generated by hbm2java
*/
@Embeddable
public class NId implements java.io.Serializable {
// Fields
private String a;
private String b;
// Constructors
/** default constructor */
public NId() {
}
/** full constructor */
public NId(String a, String b) {
this.a = a;
this.b = b;
}
// Property accessors
@Column(name="a", unique=false, nullable=false, insertable=true,
updatable=true, length=200)
public String getA() { return this.a; }
public void setA(String a) { this.a = a; }
@Column(name="B", unique=false, nullable=false, insertable=true,
updatable=true, length=30)
public String getB() { return this.b; }
public void setB(String b) { this.b = b; }
public boolean equals(Object other){.....}
public int hashCode() {....)
}
and the main class is
public class SSTest {
public static void main(String[] arg)
{
SSTest sstest = new SSTest();
sstest.addNS();
}
public void addNS()
{
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("manager1");
NId item = new NId( "111111", "111111" );
ABs ns = new ABs();
ns.setId(item);
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
em.persist( ns );
em.getTransaction().commit();
}// end of method
}// End of Class
