Hi,
I'm a relatively new Hibernate user looking to use hbm2java within ant for a webapp I am developing. I'm using the latest released hibernate-tools.jar, but the tool cannot find my .hbm.xml files, which I've placed in the "project_root/src/org/marketcharts/data/" directory and am pointing to from the hibernate.cfg.xml file in my src/ directory:
<mapping resource="org/marketcharts/data/Ticker.hbm.xml"/>
<mapping resource="org/marketcharts/data/HistoricalQuote.hbm.xml"/>


The error I am receiving is as follows:

bmccann@chameleon:~/Documents/Programs/marketTracker> ant codegen
Buildfile: build.xml

codegen:
[hibernatetool] Executing Hibernate Tool with a Standard Configuration
[hibernatetool] 1. task: hbm2java (Generates a set of .java files)
[hibernatetool] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
[hibernatetool] log4j:WARN Please initialize the log4j system properly.

BUILD FAILED
/home/bmccann/Documents/Programs/marketTracker/build.xml:227: org.hibernate.MappingException: Resource: org/marketcharts/data/Ticker.hbm.xml not found



Here is the releveant excerpt from my build.xml file which resides in the project root directory:
<!-- Load Hibernate's code generation tool -->
<taskdef name="hibernatetool"
classname="org.hibernate.tool.ant.HibernateToolTask"
classpathref="project.classpath"/>


<!-- Generate the java code for all mapping files in our source tree -->
<target name="codegen"
description="Generate Java source from the O/R mapping files">

<hibernatetool destdir="${src.home}">
<classpath refid="project.classpath"/>

<configuration configurationfile="${src.home}/hibernate.cfg.xml" />

<hbm2java />
</hibernatetool>

</target>


Any ideas or help you could give me would be much appreciated.

Thanks,
Ben

I had to remove the mapping entries from my .cfg.xml file:

<!-- Mapping files -->
<mapping resource="org/marketcharts/data/Ticker.hbm.xml"/>
<mapping resource="org/marketcharts/data/HistoricalQuote.hbm.xml"/>


And I added a fileset to the configuration:
<configuration configurationfile="${src.home}/hibernate.cfg.xml" >
<fileset dir="${src.home}">
<include name="**/*.hbm.xml"/>
</fileset>
</configuration>


This really seems like a bug to me. I'd rather not have to delete the mappings from my .cfg.xml file everytime I want to update my code.

huuh ? if the resources are in the classpath of the hibernatetool it works.

I'm not sure what you mean exactly by "in the classpath". I have not set the .hbm.xml files to be in the Java compile path which is surely not what you mean... They are however within the src directory. My first post does state the directories in which each of my files resides.
I was dumbfounded when that turned out to be the solution to my problem since it was not the behavior described in the documentation, but I tried a hundred other things none of which worked. When I put the mapping lines back in the hibernate.cfg.xml file it broke again, so that's definitely the problem as far as I can see. I'd love for this issue to get resolved in future releases, so if there's anything else I can do to help clarify the problems I've had please let me know. This problem occured whether I ran the build through eclipse or not. Also, I am using Suse 10.0 from opensuse.org

you are using mapping resource in cfg.xml, those resources need to be in the classpath of the <hibernatetool>

Thanks. You're right, this was a usage issue. I was unaware that anything other than Java classes, or jars containing Java classes, could be in a classpath. Although it's mostly an issue with my knowledge of ant, it might be helpful if the documentation made this more clear to help other newcomers.

Seems that changing the configuration line to jdbcconfiguration worked for me. Spent three long hours on this.

Look at this:

<target name="codegen" description="Generate Java source from the O/R mapping files">
<taskdef name="hibernatetool"
classname="org.hibernate.tool.ant.HibernateToolTask"
classpathref="project.classpath"/>
<hibernatetool destdir="${src.dir}">
<classpath refid="project.classpath"/>
<jdbcconfiguration configurationfile="${src.dir}/hibernate.cfg.xml"/>

<!-- <configuration configurationfile="${src.dir}/hibernate.cfg.xml">
<fileset dir="${src.dir}">
<include name="**/*.hbm.xml"/>
</fileset>
</configuration>-->
<hbm2java />
</hibernatetool>
</target>

yes...did you read the docs ? (you must have since you could write the ant file)

look at:
"JDBC Configuration for reverse engineering (<jdbcconfiguration>)"
