Hibernate Mapping Exception class not found

I'm working for several hours on this issue about hibernate mapping. I think the error could be a simple syntax mistake but I can't find it!!!
I ran into the following exception when I executed my code:
Initial SessionFactory creation failed.org.hibernate.MappingException: entity class not found: LegalFee
Exception in thread "main" java.lang.ExceptionInInitializerError
at com.plm.dao.util.HibernateUtil.buildSessionFactory(HibernateUtil.java:33)
at com.plm.dao.util.HibernateUtil.getSessionFactory(HibernateUtil.java:39)
at com.plm.dao.AppTest.main(AppTest.java:15)
Firstly, I'm using hibernate 4.2 with Java 8 and MariaDB 10.
See all configurations below.
My hibernate.cfg.xml, I removed C3P0 configuration:
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name='connection.driver_class'>com.mysql.jdbc.Driver</property>
<property name='connection.url'>jdbc:mysql://localhost:3306/PokerLeagueManager</property>

<property name='connection.password'>mypassword</property>
<property name="show_sql">true</property>
<!-- SQL dialect -->

<mapping resource="mappings/BlindStructure.hbm.xml"/>
<mapping resource="mappings/Tournament.hbm.xml"/>
<mapping resource="mappings/LegalFee.hbm.xml"/>
</session-factory>
</hibernate-configuration>
The error is on LegalFee bean so focus on it.
See the sql table creation of legalFee:
CREATE TABLE `legalFee` (
`idFee` int(11) NOT NULL,
`shortName` varchar(50) NOT NULL,
`description` varchar(200) DEFAULT NULL,
`feePercent` int(11) DEFAULT NULL,
`feeFixed` int(11) DEFAULT NULL,
PRIMARY KEY (`idFee`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
The class :
public class LegalFee implements Serializable {
/**
* generated serial uid
*/
private static final long serialVersionUID = -2259355205530727294L;
private int idFee;
private String shortName;
private String description;
private Integer feePercent;
private Integer feeFixed;
private Set<Tournament> tournaments = new HashSet<Tournament>(0);
public LegalFee() {
}
public LegalFee(int idFee, String shortName) {
this.idFee = idFee;
this.shortName = shortName;
}
public LegalFee(int idFee, String shortName, String description,
Integer feePercent, Integer feeFixed, Set<Tournament> tournaments) {
this.idFee = idFee;
this.shortName = shortName;
this.description = description;
this.feePercent = feePercent;
this.feeFixed = feeFixed;
this.tournaments = tournaments;
}
public int getIdFee() {
return this.idFee;
}
public void setIdFee(int idFee) {
this.idFee = idFee;
}
public String getShortName() {
return this.shortName;
}
public void setShortName(String shortName) {
this.shortName = shortName;
}
public String getDescription() {
return this.description;
}
public void setDescription(String description) {
this.description = description;
}
public Integer getFeePercent() {
return this.feePercent;
}
public void setFeePercent(Integer feePercent) {
this.feePercent = feePercent;
}
public Integer getFeeFixed() {
return this.feeFixed;
}
public void setFeeFixed(Integer feeFixed) {
this.feeFixed = feeFixed;
}
public Set<Tournament> getTournaments() {
return this.tournaments;
}
public void setTournaments(Set<Tournament> tournaments) {
this.tournaments = tournaments;
}
}
And lastly the LegalFee.hbm.xml:
<?xml version="1.0"?>

Thanks for your help.

If your LegalFee class is not in default package you need to provide the fully classified name of the class.
e.g "class name="com.abc.xyx.LegalFee" table="legalFee" "

org.hibernate.hql.ast.QuerySyntaxException: UserType is not mapped [from UserType]

The exception is about table not mapping to class, however I failed to debug what went wrong.
I have checked the xml configurations. the class is UserType and the database table is called UserType as well.

I appreciate any helps!

The problem is in hibernate mapping configuration:
name: should be same as class field name and
column: is the name of database table column, or the column name to be set while table creation by hibernate.
Note: The mapping file instructs Hibernate how to map the defined class to the database table.
your UserType.hbm.xml should be look like:
<hibernate-mapping>
<class name="com.howtodoinjava.entity.UserType" table="UserType">
<meta attribute="class-description">
user type
</meta>
<id name="_userTypeID" column="userTypeID" type="int">
<generator class="native"/>
</id>
<property name="_userTypeName" column="userTypeName" type="string"/>
<property name="_typeIsSuperUser" column="typeIsSuperUser" type="string"/>
</class>
</hibernate-mapping>

It turned out this is related to the HQL issue: instead of using from UserType, use from com.howtodojava.entity.UserType;
and the error message will be gone.

Can not established a connection to jdbc with Hibernate-SQL Server 2008

I made a connection to SQL server with Hibernate configuration wizard, when I click test connection, I get success message, but when I want to make hibernate mapping, I cannot I get error message, Cannot established a connection to jdbc. The below code is jdbc connection with hibernate; please say me, what is the problem?
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="hibernate.connection.url">jdbc:sqlserver://localhost; databaseName=Test</property>
<property name="hibernate.connection.username">sa</property>
<property name="hibernate.connection.password">sa123</property>
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
</session-factory>
</hibernate-configuration>
Best Regards

After looking into your code i found you did not specify the port number for database connection
<property name="hibernate.connection.url">jdbc:sqlserver://localhost; databaseName=Test</property>
There should be a port number if your trying to connect on your local machine for an example please refer following line
<property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;DatabaseName=syv</property>
Please check and let me know ...if there is any further issue
Ok here i am sending you the basic hibernate configuration : -
STEP 1 :- *Create a Java File “AddStudent” and paste the below code into that.*
//package code;
import java.sql.*;
import java.io.*;
import org.hibernate.*;
import org.hibernate.cfg.*;
public class AddStudent {
private static SessionFactory sessionFactory;
public static void main(String args[]) throws Exception {
DataInputStream d = new DataInputStream(System.in);
System.out.println("ENTER YOUR NAME");
String name = d.readLine();
System.out.println("ENTER YOUR DEGREE");
String degree = d.readLine();
System.out.println("ENTER YOUR PHONE");
String phone = d.readLine();
System.out.println("Name: " + name);
System.out.println("Degree: " + degree);
System.out.println("Phone: " + phone);
if ((name.equals("") || degree.equals("") || phone.equals(""))) {
System.out.println("All informations are Required");
} else {
try {
// begin try
sessionFactory = new Configuration().configure()
.buildSessionFactory();
} catch (Exception e) {
System.out.println(e.getMessage());
System.err.println("Initial SessionFactory creation failed."
+ e);
}
Session s = sessionFactory.openSession();
Transaction tx = s.beginTransaction();
Student stu = new Student();
stu.setName(name);
stu.setDegree(degree);
stu.setPhone(phone);
s.save(stu);
tx.commit();
System.out.println("Added to Database");
if (s != null)
s.close();
}
}
}
STEP 2 : Create a Java File “Student” paste the below code into that.
//package code;
import java.io.*;
public class Student implements Serializable {
private long id;
private String name;
private String degree;
private String phone;
public long getId() {
return id;
}
public String getName() {
return name;
}
public String getDegree() {
return degree;
}
public String getPhone() {
return phone;
}
public void setId(long string) {
id = string;
}
public void setName(String string) {
name = string;
}
public void setDegree(String string) {
degree = string;
}
public void setPhone(String string) {
phone = string;
}
public String toString() {
return name;
}
}
Step 3: Create an xml file “hibernate.cfg.xml” place the below code into that.
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory name="studentFactory">
<property name="connection.driver_class">
oracle.jdbc.OracleDriver
</property>
<property name="connection.url">
jdbc:oracle:thin:#localhost:1521:XE
</property>
<property name="connection.username">
system
</property>
<property name="connection.password">
system
</property>
<property name="connection.pool_size">5</property>
<!-- SQL dialect -->
<property name="dialect">
org.hibernate.dialect.OracleDialect
</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">false</property>
<mapping resource="Student.hbm.xml" />
</session-factory>
</hibernate-configuration>
Step 4:Create an xml File “student.hbm.xml” and place below code into that.
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping >
<class name="Student" table="Stutbl" >
<id name="id" type="long" column ="ID">
<generator class="increment"/>
</id>
<property name="name" column="name" not-null="true"/>
<property name="degree" column="degree" />
<property name="phone" column="phone" />
</class>
</hibernate-mapping>
Step 5: Add the required jar to your project
Hope it will solve your problem

Add this:
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>
and verify if your Database accept connections.

Hibernate deletes manyToMany relationship rows on fetch

I am using Hibernate4 with Spring and I am trying to map a Term class to a Document class. A term may occur in many documents and a document can contain many terms. I have read up on this, and I have attempted a number of fixes, including overriding the equals and hashCode methods.
In my database the terms and documents are stored in separated tables mediated by a relationship table. In the code here, it is called the jtable. I am using hibernates many-to-many mapping, but every time that I try to fetch a term object it simply deletes the row in the relationship table.
Here is a sample sql output that hibernate's show sql is giving out:
Hibernate: SELECT * FROM tags WHERE token='rose'
Hibernate: delete from jtable where tag_id=?
Here are the relevant classes and configs:
public class Term {
public String getWord() {
return word;
}
public void setWord(String word) {
this.word = word;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Set<Document> getDocuments() {
return documents;
}
public void setDocuments(Set<Document> documents) {
documents = documents;
}
#Override
public boolean equals(Object obj) {
if(obj.getClass() != getClass()){
return false;
}
Term term = (Term) obj;
if (hashCode() == term.hashCode()){
return true;
}
return false;
}
#Override
public int hashCode(){
return word.hashCode();
}
private String word;
private int id;
private Set<Document> documents = new HashSet<Document>();
}
And the Document class :
public class Document implements Comparable<Document> {
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public URL getUrl() {
return url;
}
public void setUrl(URL url) {
this.url = url;
}
public Integer getLength() {
return length;
}
public void setLength(Integer length) {
this.length = length;
}
public Double getRank() {
return rank;
}
public void setRank(Double rank) {
this.rank = rank;
}
#Override
public boolean equals(Object obj) {
if(obj.getClass() != getClass()){
return false;
}
Document document = (Document) obj;
if (hashCode() == document.hashCode()){
return true;
}
return false;
}
#Override
public int hashCode(){
int hash = 1;
hash *= 1 + (length == null ? 0 :length);
hash *= 2 + (rank == null ? 0 :rank);
hash *= 3 + (title == null ? 0 : title.hashCode());
hash *= 4 + (url.hashCode());
return hash;
}
#Override
public int compareTo(Document document) {
return rank.compareTo(document.getRank());
}
private int id;
private Integer length;
private Double rank;
private String title;
private URL url;
}
