SQLGrammarException: impossible d'exécuter la requête

Je suis à l'aide de Struts2 & Hibernate et l'obtention d'erreur ci-dessous lorsque j'ai cherché des données avec de la ficelle test mais fonctionne pour moi quand j'ai cherché avec le numérique 111. Je suis l'obtention de cette valeur, de la fève de classe et défini la propriété de type chaîne de caractères dans la classe d'haricot.

Ci-dessous je suis en fournissant le code:

public String retrieveRecords() 
{    
    String empId = p.getEmpId();
    String paramValue = "";
    if(empId !=null)
        if(!(empId.isEmpty()))
        paramValue =" where b.empId="+empId;

    String empName = p.getEmployeeName();
    if(empName !=null && empName != "")
    {
        if(!(empName.isEmpty())){
        if(paramValue == "")
         paramValue =" where b.employeeName="+empName;
        else
         paramValue =paramValue + " and b.employeeName="+empName;
        }
    }
    System.out.println("=========paramvalues===="+paramValue);
    recList = (List<RequestBean>) session.createQuery("from RequestBean b"+paramValue).list();
    request.setAttribute("rec", recList);
    System.out.println("got size"+recList);
    return SUCCESS;
}
