Thank you for reading my post
Hibernate version: 3.2

I have problem with loading hibernate.cfg.xml in my application.
here is the code snippet:

Code:

package learn_hiber.chapter4;

import java.io.File;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;

public class GenerateSchema
{

    public static void main(String[] args)
    {
       // Amended to allow a path (to the hibernate.cfg.xml) to
       // be passed to the configuration.
        AnnotationConfiguration cfg = ExampleConfiguration.getConfig();;
        
        cfg.addFile(new File("learn_hiber/hibernate.cfg.xml"));
        
        SchemaExport schemaExport = new SchemaExport(cfg);
        schemaExport.create(true, true);
    }
}

when i try to run this code it return

Code:

Exception in thread "main" org.hibernate.MappingException: Could not read mapping document from file: learn_hiber\hibernate.cfg.xml
        at org.hibernate.cfg.Configuration.addFile(Configuration.java:297)
        at learn_hiber.chapter4.GenerateSchema.main(GenerateSchema.java:17)
Caused by: java.io.FileNotFoundException: learn_hiber\hibernate.cfg.xml (The system cannot find the path specified)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:106)
        at org.hibernate.cfg.Configuration.addFile(Configuration.java:294)
        ... 1 more
Java Result: 1

while my directory structure is like:
src folder contains:
-learn_hiber\chapter4
-learn_hiber\hibernate.cfg.xml
-learn_hiber\log4j.properties

the chapter 4 folder contains my annotated classes source code
src is roof folder for all my source codes.
Thanks

Maybe you should try with slash (/) instead of antislash ? I suspect the system is understanding \ as a "despecializer" in your case.

\ is not to be used in Java, it's a bizarre windows choice, because it can sometimes conflict with the usual \ used in programming (\n, \r, \t, etc.). When asking for paths, Java will convert your slashes for the right platform (see System.getProperties() => one is indicating what it used : / or \, but code should always use /).

Thanks, but it does not helps.
it looks like that it does not find the mapping file even after changing.
Thanks

Have you tried using a full path? Sometimes a FileNotFoundException is just that. It can't find your file. Using a full path might help figure out if your relative path is correct.
