Getting Exception while connecting Spring to hibernate using H2 database

Getting Exception while connecting Spring to hibernate using H2 database - java

I am getting below exception:

I have tried to link through JDBC and it's working fine.

salary field has int type, but there is double in the hibernate mapping

This might be caused because the hibernate trying retrieving the dtd file. so, the workaround could be :
change the value of the dtd from that to "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"
Create your own function to parse the configuration then passed to the hibernate like this
public static Document parseConfiguration(String resourcePath) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false); <-- the magic is here
DocumentBuilder builder = factory.newDocumentBuilder();
return builder.parse(builder.getClass().getResourceAsStream(resourcePath));
}

I am not getting the error you are getting, though I fixed lot of errors in your entity (properties defined in the mapping file not present in the entity). I have reached the step where it is trying to insert the record, so I am well past the stage where you are getting the error.
By looking into the hibernate source file (org.hibernate.cfg.Configuration.addInputStream(Configuration.java:499)) which is throwing error, hibernate is not able to reach your mapping xml file.
Please double check if the mapping file is at proper location and also readable.
Also make sure you have correct version of hibernate jar in the classpath.

can anyone help me to getting out from this errors/exceptions.
Thanks in advance.

I am not exactly sure whether this solution will work just a small hunch.
Replace :
Resource r = new ClassPathResource("applicationContext.xml");
BeanFactory factory = new XmlBeanFactory(r);
EmployeeDao dao = (EmployeeDao)factory.getBean("d");
with :
ApplicationContext r = new ClassPathXMLContext("applicationContext.xml);
Employee dao = r.getBean("d");

Spring + Hibernate, can not read xml error

I am a newbie in Spring + Hibernate, but I have worked on this problem for last one day. I still can not figure out what is the root cause, and what should I do. So, thank you in advance if any one can give me some advice.

}
Thank you so much for any advice!

The properties should be declared like below inside your sessionFactory Bean.
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
</props>
so your sessionFactory bean would be like below.
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>com/domain/Employee.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
</props>
</property>

sometimes there is a chance of cant pick ur config files because of compiler dont konw which file shoul it take for configuration.so for this reason u should explicitly import those config file via 2 methods as i know
1)by using class
#Configuration
#ImportResource(value = {"classpath:{filename-within-resource}/Employee.hbm.xml"},"classpath:{filename-within-resource}/ApplicationContext.cfg.xml")
public class CommonSolutionConfig {
}
2)by using xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
<import resource="classpath:{filename-within-resource}/Employee.hbm.xml"/>
<import resource="classpath:{filename-within-resource}/ApplicationContext.cfg.xml"/>
</beans>
hopefully it will solve ur problem

Things you need to fix:
1 - put the JAR (javaee-api) in your LIB folder
http://mvnrepository.com/artifact/javax/javaee-api/7.0
2 - if you are using Maven, add the following dependency
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
</dependency>
3 - Configure your artifact and include this jar, allowing to be deployed
4 - Put the javaee-api jar in your tomcat/jboss lib folder

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.

You didn't configure mapping for the object Emp. The configuration file hibernate.cfg.xml should contain the mapping to the resource Emp.hbm.xml.
<mapping resource="info/inetsolv/Emp.hbm.xml"/>

I had similar problem for a simple Console application trying to use Hibernate. The solution I arrived to make the add the "packagesToScan" property explicitly for LocalSessionFactoryBean.
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="packagesToScan" value="com.mg.learning.spring.orm"/> <--- this SOLVED!
<property name="hibernateProperties">
<props>
<prop key="dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
</props>
</property>
</bean>

#Sandhu Santakumar , answer is absolutely right.
Just adding the reason behind this.
By default the JBoss hibernate reverse engineering tool maps class inside the mapping tab but resource attribute is the required attribute that hibernate.cfg.xml should have.
class attribute is optional.
e.g. if your mapping is like this
resource is mandatory attribute and class is optional attribute.
Hope this additional information helps.
