Subject Problem build and run hellojpa using Maven
Date Thu, 22 Apr 2010 14:45:32 GMT
Hi

I have successfully ran the hellojpa sample as described in the getting
started with Netbeans and Ant.

Now, I'm trying to build and run the same sample using Maven.

When the goal exec:exec is executed, the following ArgumentException is
thrown:

0  WARN   [main] openjpa.Runtime - The configuration property named
"openjpa.Id" was not recognized and will be ignored, although the name
closely matches a valid property called "openjpa.Id".
Exception in thread "main" <openjpa-1.2.2-r422266:898935 nonfatal user
error> org.apache.openjpa.persistence.ArgumentException: Attempt to cast
instance "hellojpa.Message@1094d48" to PersistenceCapable failed.  Ensure
that it has been enhanced.
FailedObject: hellojpa.Message@1094d48

        at hellojpa.Main.main(Main.java:54)


Here are the snippets of my pom.xml:

<dependency>
    <groupId>org.apache.openjpa</groupId>
    <artifactId>openjpa</artifactId>
    <version>1.2.2</version>
    <scope>compile</scope>
</dependency>
<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derby</artifactId>
    <version>10.5.3.0</version>
</dependency>
<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.1.1</version>
    <configuration>
        <executable>java</executable>
        <arguments>

 <argument>-Dopenjpa.ConnectionDriverName=org.apache.derby.jdbc.EmbeddedDriver</argument>

 <argument>-Dopenjpa.ConnectionURL=jdbc:derby:openjpa-database;create=true</argument>
            <argument>-Dopenjpa.ConnectionUserName=</argument>
            <argument>-Dopenjpa.ConnectionPassword=</argument>

 <argument>-Dopenjpa.jdbc.SynchronizeMappings=buildSchema</argument>
            <argument>-Dopenjpa.Log=DefaultLevel=WARN,SQL=TRACE</argument>
            <argument>-classpath</argument>
            <classpath/>
            <argument>hellojpa.Main</argument>
        </arguments>
    </configuration>
</plugin>


Do you have any idea of what could be the problem?
