Hello!

I'm trying to get a simple web project to work with JBoss 5.1, Eclipselink and JPA.

My error is pretty similar to the one in thread http://community.jboss.org/thread/146562,

although  it doesn't have any solution...

When I deploy the project to JBoss it displays this info:

14:28:05,409 WARN  [SaxJBossXBParser] schema_reference.4: Failed to read schema document 'http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. @ vfszip:/C:/jboss-5.1.0.GA/server/default/deploy/pt.jboss.teste.war/WEB-INF/classes/META-INF/persistence.xml[4,28]

EclipseLink may be unable to get a spec mandated temporary class loader from the server, you may be able to use static weaving as an optional workaround.

Then, when I try to access the application on the browser it throws this Exception:

This is my persistence.xml file

{code:xml}

        </properties>
    </persistence-unit>
</persistence>

{code}

My datasource configuration in JBOSS_HOME/server/default/deploy/oracle-ds.xml

{code:xml}

<datasources>
 <no-tx-datasource>
 <jndi-name>OracleDS</jndi-name>
 <use-java-context>true</use-java-context>
 <connection-url>jdbc:oracle:thin:@XXXhost:1521:XXXsid</connection-url>
 <driver-class>oracle.jdbc.OracleDriver</driver-class>

 <metadata>
 <type-mapping>Oracle9i</type-mapping>
 </metadata>
 </no-tx-datasource>
</datasources>

{code}

This is the code I use to try to get the EntityManager

{code}
EntityManagerFactory emf = Persistence.createEntityManagerFactory("example");
EntityManager em = emf.createEntityManager();
{code}

The eclipselink.jar is in JBOSS_HOME/common/lib,

but I also tried to put it in JBOSS_HOME/server/default/lib and in my project lib.

Alway the same error...

Any help appreciated...

Thanks!
