What can be the error any help??
Try changing the DOCTYPE to this:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
This means that hibernate will load the DTD from classpath - it is usually included in hibernate jar in org/hibernate directory.
However, we use hibernate 3.5.6 - I don't hnow if this approach still works in the newer version - give it a try. The benefit of this is that you are completely independent on internet connection, proxies and so on.
Hibernate Configuration File Location
The first solution was to provide the DTD file location in the system using classpath. So the DocType that worked offline would be;
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
Use SourceForge DTD URL with SYSTEM
Another solution I found working is when I change the DTD URL to SourceForge and changed the declaration from PUBLIC to SYSTEM.
So below will also work if your system is offline.
<!DOCTYPE hibernate-configuration SYSTEM
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
I am new to Hibernate, so I have few dumb questions hope someone would be able to assist me. I have a query in regards to configuring hibernate file i.e. hibernate.cfg.xml file. Normally we configure it as below :
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hbm2ddl.auto">update</property>
<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
<property name="connection.url">jdbc:oracle:thin:#localhost:1521:xe</property>
<property name="connection.username">system</property>
<property name="connection.password">oracle</property>
<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<mapping resource="employee.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Where the considers relevant mapping files. Lets say I have another mapping file, call it company.hbm.xml file and have a one-to-many relationship with employee.hbm.xml file. So, as and when the number of mapping files increases we include them into tag.
Query : How is it different to include multiple mapping files with individual tag from having just a single mapping file with all the relevant mappings.
Appreciate your response
Because such separation is cleaner. Single file with whole configuration tends to grow up and to become a yet another huge, unmaintainable and unreadable XML file.
Please also note, that using annotations right inside your model classes seems to be the right way for you (just as #Shiju Babu stated).

Please check if the jars of Hibernate are added properly in your dev environment.
You might be getting the error because you've wrong DTD declaration in your mapping file.
Change it to the following & then try:
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
I'm trying to run HQL queries in IntelliJ's Hibernate Console. I've added the datasource to the Data Sources view and added my hibernate.cfg.xml to the Hibernate facet such that in appears in the Persistence view. The content of hibernate.cfg.xml is:

The .hbm.xml is shown in green, whereas if I change it to a file that doesn't exist it is shown in red, so it seems that IntelliJ can find it. However, if I run a simple query in the console like:
from XmlApiDlrMapping xmlApiDlrMapping
where xmlApiDlrMapping.retries = 5
I get an error:

This only happens when I'm offline. Does hibernate try to read the DTD when parsing the config? What's the root cause here?
Here is my hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

Hibernate can resolve the DTDs locally (without a network connection).
Your DOCTYPE is using the new namespace (http://www.hibernate.org/dtd/) for Hibernate 3.6, so you might have an older version of the Hibernate libraries in your classpath.
I experienced the same issue after upgrading to Hibernate 3.6.8.Final. I had multiple versions of hibernate3.jar on the classpath causing an old incompatible version of the DTD Entity Resolver to be loaded which only works with the old namespace (http://hibernate.sourceforge.net/). For reference, here's a link to the newer DTD Entity Resolver.
I'm using hibernate3-maven-plugin which has a transitive dependency on an older version of Hibernate so I just had to specify a plugin dependency on Hibernate 3.6.8.Final.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
...
</configuration>
<dependencies>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>3.6.8.Final</version>

It is not possible because, hibernate jar files is also load the some dtd content but slow internet connection it is worked.
(1) Hibernate Configuration File Location
The first solution was to provide the DTD file location in the system using classpath. So the DocType that worked offline would be;
<!DOCTYPE hibernate-configuration SYSTEM

So below will also work if your system is offline.
<!DOCTYPE hibernate-configuration SYSTEM

Hibernate Work Offline
Another Way is You should download DTD file and set the file path.
and also set the dtd file location in java Build path (eclipse).

In case this helps anyone else ... my problem was that I was including the wrong Maven artifact. I was including spring-hibernate3:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-hibernate3</artifactId>
<version>2.0.8</version>
</dependency>
Replacing it with spring-orm fixed this issue:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>2.5.6.SEC03</version>
</dependency>
Just check this site https://forum.hibernate.org/viewtopic.php?f=1&t=943281&start=0
Hope that it will solve your problem.
I think you are using Hibernate3 jar file, but the Hibernate4 DTD file.
so the solution is choose one of them: 3 or 4.
BTW, I strongly recommend you using Maven for the jar dependency management.
You can use an internal DTD (not pretty IMO) or download the DTD file to your filesystem.
Check W3Schools' for more information: http://www.w3schools.com/dtd/dtd_intro.asp
In your mapping files, you must have the exactly SAME doctype as found in the mapping DTD's.
Then and only then you'll see that the dtd's found in hibernate3.jar can be found through the classpath, and running behind a firewall, stand-alone, etc. will be no problem at all.
No local dtd's in your projects to solve this issue, no code to intercept. :-)
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
The same is of course applicable for the configuration file.
I had this problem too.
My DOCTYPE was:
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">
It should be:
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
Can you see the difference?
The first URI has NOT www and the second URI has www
So, the www in the URI must be declared in the configuration file and in all the mapping files.
It is not your case (cause I can see you have the http://www... URI), but it may help somebody.
Regards.
I have used following method to skip the validation of Doctype in the Configuration file
Code:-
public static Document parseConfiguration(String resourcePath) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false);
DocumentBuilder builder = factory.newDocumentBuilder();
File f=new File(resourcePath);
FileInputStream fs=new FileInputStream(f);
Document dtd = builder.parse(fs);
return dtd;
}
public static void main(String[] args)
{
Document dtd=null;
try {
dtd = parseConfiguration("src/hibernate.cfg.xml");
} catch (Exception e) {
e.printStackTrace();
}
SessionFactory factory=new AnnotationConfiguration()
.configure(dtd).buildSessionFactory();
/*
Now this code worked for me
You just have to use annotation instead of hbm.xml file because I was not able to skip the validation of mapping file as it is written inside the cfg.xml file
Reply if you got some other answer to run hibernate application in offline */
instead of
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
use
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
it worked fine for me
Alberto Daniel actually is right, indeed adding the "www." fixed for me the problem.
I guess, since the hibernate-core.jar file contains the dtd files, exactly the location http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd is treated somehow specially by the XML parser, so that the dtd from the jar file is used. I did not verify this, but it may be an explanation. However: Thank you Alberto!
Regards.
