SchemaExport - Could not compile the mapping document

Using Hibernate 2.1 Final, Hibernate Extensions 2.0.2, MySQL 4.0.16, Connector 3.09 and generated Foo.java from Foo.hbm.xml with hbm2java.

SchemaExport produced the following error message:

Anything wrong with my configuration? Or a bug?

eh - have you compiled Foo.java and put it in the classpath of schemaexport ? ....hibernate needs the class to e.g. perform the schemaexport...

You are a star!

The reference "19.1.2. Running the tool" wasn't very specific on that.

Actually, in my case, I did compile the needed class. Here are the first few lines of output from my schemaexport ant task (mainly to show that the .class file is in the classpath):

And here is the relevant portion of my ant build script:

I'm using Hibernate 2.1.1 with JBoss 3.2.3, SQL Server 2000 SP3 with JDBC driver SP2 from Microsoft. Is there anything else I missed? Thanks.

I promise you - the class com.mycompany.mcsts.model.hibernate.MailingAddress is NOT on your classpath - otherwise that error would not occur!

I can see your path contains C:\java\bin\eclipse-2.1.2\workspace\MCSTS\build\com\mycompany\mcsts\model\hibernate\
MailingAddress.class - this is NOT the correct way to have classes on the path. it should more be something like:
C:\java\bin\eclipse-2.1.2\workspace\MCSTS\build

And your ant path id="hibernate.path" refers to concrete *.class's instead of adding directories. This is basic java stuff - please go check out something like http://www.kevinboone.com/classpath.html

Hi all, sorry my bad english,
I look the thread, but my problem "persists".

I trying to create a simple project that contains 2 classes (in package) that represents a one-to-many relationship (one people have many cars).

My java files are in:
C:\TRABALHO\Auctions\org\hibernate\auctions

My java sources are declared as:

Code:

package org.hibernate.auction;
import java.util.*;
/**
 * Created on Dec 18, 2003
 * @author mrack
 * @hibernate.class
 */
public class People extends Persistent { //Persistent have id attribute...
  private List cars = new Vector();
  //...
  /**
  * @hibernate.bag name="cars"
  * @hibernate.collection-key column="owner"
  * @hibernate.collection-one-to-many class="Car"
  */
  public List getCars() {
    return cars;
  }
}

and

Code:

package org.hibernate.auction;
import java.util.*;
/**
 * Created on Dec 18, 2003
 * @author mrack
 * @hibernate.class
 */
public class Car extends Persistent { //Persistent have id attribute...
  private People owner;
//...
  /**
   * @return Returns the owner's car
   * @hibernate.many-to-one class="People"
  */
  public People getOwner() {
    return owner;
  }
}

My compiled java classes are in:
C:\TRABALHO\Auctions\org\hibernate\auctions

My ant script generate .hbm files correctly at
C:\TRABALHO\Auctions\org\hibernate\auctions

In other words:
C:\TRABALHO\Auctions\org\hibernate\auctions\People.java
C:\TRABALHO\Auctions\org\hibernate\auctions\Car.java
C:\TRABALHO\Auctions\org\hibernate\auctions\People.class
C:\TRABALHO\Auctions\org\hibernate\auctions\Car.class
C:\TRABALHO\Auctions\org\hibernate\auctions\People.hbm.xml
C:\TRABALHO\Auctions\org\hibernate\auctions\Car.hbm.xml

The problems occurs when I try to execute schemaExport, like below:

java -cp %CP% net.sf.hibernate.tool.hbm2ddl.SchemaExport --text --output=schema.ddl org\hibernate\auction\*.hbm.xml

at C:\TRABALHO\Auctions directory.

Note: var CP contains: ;lib\cglib2.jar;lib\commons-collections.jar;lib\commons-logging.jar;lib\dom4j.jar;lib\hibernate-tools.jar;lib\hibernate2.jar;lib\jdbc2_0-stdext.jar;lib\JSQLConnect.jar;lib\jta.jar;lib\odmg.jar;lib\xalan.jar;C:\TRABALHO\Auctions

The problem is that class "Car" was not found by schemaExport.

The workaround that I found was put fully-qualified name of "Car" and "People" in xdoclet-hibernate tags, like below:

Code:

package org.hibernate.auction;
import java.util.*;
/**
 * Created on Dec 18, 2003
 * @author mrack
 * @hibernate.class
 */
public class People extends Persistent { //Persistent have id attribute...
  private List cars = new Vector();
  //...
  /**
  * @hibernate.bag name="cars"
  * @hibernate.collection-key column="owner"
  * @hibernate.collection-one-to-many class="org.hibernate.auction.Car"
  */
  public List getCars() {
    return cars;
  }
}

and

Code:

package org.hibernate.auction;
import java.util.*;
/**
 * Created on Dec 18, 2003
 * @author mrack
 * @hibernate.class
 */
public class Car extends Persistent { //Persistent have id attribute...
  private People owner;
//...
  /**
   * @return Returns the owner's car
   * @hibernate.many-to-one class="org.hibernate.auction.People"
  */
  public People getOwner() {
    return owner;
  }
}

The question is: How I can execute schemaExport without use fully-qualified class-names in xdoclet-hibernate tags? Is a erroneous classpath configuration?

Thanks for all.

You have to fully qualify the class names in the XDoclet tags.

Otherwise, the schema export (and the normal hibernate startup) are going to look for classes in the default/no package.
