Did you start your hsql first?

mvn exec:java -Dexec.mainClass="org.hsqldb.Server" -Dexec.args="-database.0 file:target/data/tutorial"

I had to launch mvn compile

And a new error.
Now my problem is that hibernate.cfg.xml is not found.

Where should i put this file?
l have tried the root of the project and the same folder than EventManager.

If you put under src/main/resources, maven will copy it to class path

Thanks.
I have already corrected this error.
But now it's resource: org/hibernate/tutorial/domain/Event.hbm.xml that is not found.

Event.hbm.xml is in src/main/java/org/hibernate/tutorial/domain with Event.java.

But it's not duplicated with Event.class after a "mvn install" command.

Natoine (or anybody else!):
I have encountered what appears to be the same error as you - I get a resource not found error concerning org/hibernate/tutorial/domain/Event.hbm.xml when running the Maven exec command to invoke the EventManager class file. That's after I run the "mvn compile" command in the root folder (where my pom.xml and src and target folders are). The compile step is successful - it puts the hibernate.cfg.xml and log4j.properties files in the target\classes folder and the EventManager.class, Event.class, and HibernateUtil.class files in their appropriate folders.

Before running the Maven exec command for EventManager, I did run the Maven exec command for org.hsqldb.Server in a separate command window, and it appeared to have no errors or warnings.

The compile does give a "warning", as follows: "[WARNING] Using platform encoding (Cp1252 actually) to copy filtered resources, i.e. build is platform dependent!" I don't know if that is important. My platform is Windows XP pro, 32 bit.

The compile doesn't copy the Event.hbm.xml anywhere in the target folder, however. I'm thinking this is a problem. I copied that file manually to the target folder, and then ran the Maven exec again for EventManager, and it appeared to work.

So I guess my open question is why didn't Maven copy the Event.hbm.xml file to the target folder?

(Obviously I'm a Maven and Hibernate newbie, so please forgive my absolute ignorance! I did see that it's possible to generate java code from the *.hbm.xml file, but that doesn't appear to be part of the Tutorial, at least not yet - I'm still working my way through the first page of it!)

Hi all,
I did not succed in starting HSQLDB server using maven command line:
Code:
mvn exec:java -Dexec.mainClass="org.hsqldb.Server" -Dexec.args="-database.0 file:target/data/
I am receiving this error message from the command line:
    C:\Users\blutch009>mvn exec:java -Dexec.MainClass="org.hsqldb.Server" -Dexec.arg
    s="-database.0 file:target/data/tutorial"

I use Windows Vista, JDK 6, mvn 2.2.1. I am surprised when they say that mojo:java requires a project with an existing pom.xml. Do I have to create a pomm.xml file to have the server started using maven exec plugin? Could you help me?

Location: Toronto
I was able to solve the resource not found error by creating a packaged named org.hibernate.tutorial.domain in the source folder src/main/resources. Maven will copy the resources to the correct location in the target directory. It won't copy any non java files into the target WEB-INF/classes folder from src/main/java.

My directory layout is now:

/project
pom.xml
...other files
/src/main/java
...../org/hibernate/tutorial/domain
..........Event.java
..........Person.java
/src/main/resources
.....hibernate.cfg.xml
...../org/hibernate/tutorial/domain
..........Event.hbm.xml
..........Person.hbm.xml
