org.hibernate.InvalidMappingException: Could not parse mapping document from resource customercare.h

[piyal sengupta]

Hi iam new to hibernate.
i m doing a toy project in jsp .At the backend i m using hibernate.
Presently i have created two bean classes user and problemsummary.


user class.

package customer;

public class User {
public String id;
public String pwd;
public String role;
DBLayer dbObj=new DBLayer();
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;

}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}

public boolean isRegister(String uid1,String pwd1)
{
boolean flag=false;

flag= DBLayer.login(uid1,pwd1);
System.out.println(" fff in user isRegistration is called");

return flag;
}

}


another class


package customer;

import org.hsqldb.types.Binary;

public class ProblemsSummary {


public ProblemsSummary()
{

}
private String id;
private String email;
private String sw_type;
private String os;
private Binary problem ;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getSw_type() {
return sw_type;
}
public void setSw_type(String sw_type) {
this.sw_type = sw_type;
}
public String getOs() {
return os;
}
public void setOs(String os) {
this.os = os;
}
public Binary getProblem() {
return problem;
}
public void setProblem(Binary problem) {
this.problem = problem;
}
public void setAllValues(String id,String email,String sw,String os,Binary problem )
{

}

}
hibrenate utility class


package customer;

import java.util.Iterator;
import java.util.List;

import javax.transaction.Transaction;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hsqldb.types.Binary;

public class DBLayer {

public static Session getSession()
{
SessionFactory sessionFactory=null;
Session session=null;
try{
sessionFactory=new Configuration().configure().buildSessionFactory();
session=sessionFactory.openSession();
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return session;
}

public static synchronized boolean login(String uid ,String pwd)
{
Session session=getSession();
int role=0;
User user=new User();
boolean flag=false;
String sql="from User as user where id='"+uid+"' and pwd='"+pwd+"'";
System.out.println(" fff "+sql);

try{
session.beginTransaction();
List query=session.createQuery(sql).list();
Iterator it=query.iterator();
if(it.hasNext())
{
flag=true;
System.out.println(" fff flaf value in dblayer"+flag);

}

}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
session.getTransaction().commit();
session.close();
return flag;
}

public static synchronized void insertProblem(String id,String email,String sw,String os,Binary problem )
{
Session session=getSession();
ProblemsSummary ps=new ProblemsSummary();
//ps.setId(id);
//ps.setEmail(email);
//ps.setSw_type(sw);
//ps.setOs(os);
//ps.setProblem(problem);

session.save(ps);
session.clear();

}

}

Which Database are you using? MySql or HQLDB.

because you are using dialect & drivers in Hibernate Mapping file are of MySql and lib's are of HQLDB

I think I put the wrong table name.thats why it was giving error.
