Could not read mappings from resource Error

cash1981 · **Joined:** Mon Sep 04, 2006 7:18 am **Posts:** 45

Hello all. I am using
Hibernate version: 3.1 with Eclipse 3.2
This is my package:

This is my project:
$project/src/no/detnye/moteguiden/hibernate.cfg.xml
$project/src/no/detnye/moteguiden/hibernate.properties

$project/src/no/detnye/moteguiden/hibernate/HibernateUtil.java
(The same from the tutorial)

$project/src/no/detnye/moteguiden/pojos/FargeData.java
$project/src/no/detnye/moteguiden/pojos/FargeData.hbm.xml

$project/bin/log4j.properties
$project/bin/hibernate.properties
These are the same as in my $project/src/no/detnye/moteguiden/ files, because I didn't know exactly where the configuration files should be

$project/bin/*.class (ALL java class files)

Mapping documents: FargeData.hbm.xml

Code:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class
        name="no.detnye.moteguiden.model.FargeData"
        table="farge"
        lazy="false"
    >
        <cache usage="read-write" />

        <id name="id" column="id" type="java.lang.Integer">
            <generator class="increment" />
        </id>

        <property
            name="fargenavn"
            type="java.lang.String"
            update="true"
            insert="true"
            column="fargenavn"
            unique="true"
            not-null="true"
        />

        <set
            name="produktfarger"
            lazy="false"
            cascade="none"
            sort="unsorted"
        >

            <key column="fargeid">
            </key>

            <one-to-many
                  class="no.detnye.moteguiden.model.ProduktFargeData"
            />

        </set>
    </class>
</hibernate-mapping>

My Test class is as follows:

Code:

       Session session = HibernateUtil.getSessionFactory().getCurrentSession();
       assertNotNull(session);
        Criteria criteria = session.createCriteria(ForhandlerData.class);
      
      try {
         List forhandlerListe = criteria.list();
         
         for (int i = 0; i < forhandlerListe.size(); i++) {
            System.out.println("List contains: " + forhandlerListe.get(i));
         }
      } catch (Exception e) {
         e.printStackTrace();
      }

When I run this example I get the following exception:

Full stack trace of any exception that occurs:

If someone could please help me on how to set up hibernate correctly I would appreciate it and give alot of points :)
I can also see that I have chosen to output sql but the hibernate.properties file doesnt seem to be read. So maybe the problem is that hibernate.properties and hibernate.cfg.xml is not read! How can I set these to be read? In the tutorial it said I should have them in the classpath (I didnt know where to put them, so I put them in the package)
The exception says:
13:15:44,668 ERROR XMLHelper:61 - Error parsing XML: XML InputStream(18) Element type "id" must be followed by either attribute specifications, ">" or "/>".
But I have checked my FargeData.hbm.xml file and this is well formed.
So I am quite confused :(

Please guys and girls. I really need help with this one. I have published all information, and this should be straight clean and cut for you hibernate gurus out there.

I managed to remove the first warning about the id not correct, even though I really don't understand why I got that warning, but I still get the Exception.

its a simple xml error.

the file you shows does not have an error so you must have told hibernate to parse something different.

It doesnt seem like you have read my post, only looked at the last line of the exception.
As I told, I fixed the xml "error". Because I feel there is no error since I checked if it is well-formed and it came back true.

Here is the new output a few lines:

Code:

9:36:08,640 DEBUG DTDEntityResolver:24 - recognized hibernate namespace; attempting to resolve on classpath under org/hibernate/

SessionFactory is null [/b] <-- What does this mean? 

I have tried to change my package, I have tried to put everything in the
$project/bin file, because if hibernate.cfg.xml and hibernate.properties is not in the bin directory, it doesnt load. So I tried to put everything there, but it still says it cannot read mappings from my FargeData.hbm.xml

if you could show the full exception stack trace then it might explain itself much better.

Caused by: org.hibernate.MappingException: class no.detnye.moteguiden.model.FargeData not found while looking for property: id

Seems like what I thought. It cannot find FargeData.class, and this class is located in
$project/bin/no/detnye/moteguiden/model/FargeData.class

The reason why it is in bin is because I have put this as default output for eclipse.

I found a little error.
In my Fargedata.hbm.xml file I had the wrong package name.

I changed the value from no.detnye.moteguiden.model.FargeData
too

<hibernate-mapping>
<class
name="no.detnye.moteguiden.pojos.FargeData"
table="farge"
lazy="false"
>
<cache usage="read-write" />

<id name="id">
<generator class="increment" />
</id>

But still I get this following error:

I have no idea what I did, but it seems that hibernate has started reading the mapping files. Although I get a new exception I believe I will be able to fix that myself.

The only thing I did was to change the id generator class from increment to sequence.

I will post if I get more trouble underway.

I sorted out the problem.

Since I was not mentioning about the Id, it wasn't working.

Now what if I don't have ID what need to be done.

If you dont have id? I think it is always wise to have id. My problem was also in the id. I had increment, but I changed it to assigned. Also I had comments in between the attributes and that is wrong, also I was using the wrong package name. You tend to get blind when you look at the same code your self.
