hibernate.propery file is missing in ur hibernate program.
create the hibernate.property file with proper Dialect and url etc..

[saravana kumar]

Hi Sundar

i have created hibernate.propertoes which has the following settings.

hibernate.dialect net.sf.hibernate.dialect.DB2Dialect
hibernate.connection.driver_class = com.ibm.db2j.jdbc.DB2jDriver
hibernate.connection.url = jdbc b2j:C:/Cloudscape/cloudscape;create=true
hibernate.connection.username = emp
hibernate.connection.password = emp

hibernate.propery file is missing in ur hibernate program.

Ehm...it doesn't seem to be - at least the stack trace does log that its loading properties from hibernate.properties.


The actual error:

Could not find a setter for property empid in class src.hibernateEmp.Emp

comes when your mapping file defines a property which isn't supported by method in your POJO. In this case it seems Emp doesn't have the appropriate setEmpid([param]) method in it.

hi Paul

i have proper set method in Emp class. the code is

package src.hibernateEmp;
public class Emp
{
private int empid;
private String empname;
private int deptno;
private String deptname;
private String designation;

public void setEmpId(int empid)
{
this.empid = empid;
}
public int getEmpId()
{
return empid;
}
public void setEmpName(String name)
{
empname = name;
}
public String getEmpName()
{
return empname;
}
public void setDeptNo(int dno)
{
deptno = dno;
}
public int getDeptNo()
{
return deptno;
}
public void setDeptName(String dname)
{
deptname = dname;
}
public String getDeptName()
{
return deptname;
}
public void setDesignation(String desig)
{
designation = desig;
}
public String getDesignation()
{
return designation;
}

}

[Paul Sturrock]

Hmm. Can you post emp.hbm.xml?
