I'm new to hibernate and am trying to learn it. The tutorial at http://docs.jboss.org/hibernate/core/3. ... orial.html I try to start the hsqldb server with the mvn exec:java -Dexec.mainClass="org.hsqldb.Server" -Dexec.args="-database.0 file:target/data/tutorial" command and I get the following error:

Hi,

I am having the same problem. Apparently each dependency needs a version tag, but I am too new to Maven/Hibernate to know which version is right, where to place the jars, etc.

I am writing with the hope that someone would correct the tutorial, because it's very frustrating for new users when even the very first example does not work properly:

URL: http://docs.jboss.org/hibernate/stable/ ... orial.html
Section: "1.1.1. Setup"

Thanks a lot!

OK, finally I've been able to find a solution. Apparently you need to define version tags for all dependencies in the POM, and you better pick versions that match each-other well! Otherwise you get various confusing run-time messages.

I use:
hibernate-distribution-3.5.0-Beta-2,
hsqldb-1.8.1.1,
slf4j-1.5.8

I had to register my local versions of hsql and slf4j:
Code:
   mvn install:install-file -DgroupId=org.slf4j -DartifactId=slf4j-simple -Dversion=1.5.8 -Dpackaging=jar -Dfile=D:/java/slf4j-1.5.8/slf4j-simple-1.5.8.jar
   mvn install:install-file -DgroupId=hsqldb -DartifactId=hsqldb -Dversion=1.8.1.1 -Dpackaging=jar -Dfile=D:/java/hsqldb-1.8.1.1/lib/hsqldb.jar

and my pom.xml looks like this:

Code:
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <groupId>org.hibernate.tutorials</groupId>
    <artifactId>hibernate-tutorial</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <name>First Hibernate Tutorial</name>

    <build>
         <!-- we dont want the version to be part of the generated war file name -->
         <finalName>${artifactId}</finalName>
    </build>

    <dependencies>
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>3.3.2.GA</version>
        </dependency>

        <!-- Because this is a web app, we also have a dependency on the servlet api. -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.5</version>
        </dependency>

        <!-- Hibernate uses slf4j for logging, for our purposes here use the simple backend -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
            <version>1.5.8</version>
        </dependency>

        <!-- Hibernate gives you a choice of bytecode providers between cglib and javassist -->
        <dependency>
            <groupId>jboss</groupId>
            <artifactId>javassist</artifactId>
            <version>3.1</version>
        </dependency>

      <dependency>
         <groupId>hsqldb</groupId>
         <artifactId>hsqldb</artifactId>
         <version>1.8.1.1</version>
      </dependency>
    </dependencies>
</project>


Note that at present there is no Maven descriptor for hibernate 3.5, so I used 3.3.2.GA.

Good luck
