Colegas,

Criei um projeto com o jboss tools e quando tento executá-lo recebo os
erros abaixo.
Parece-me que ele não encontra o datasource. É isso mesmo? Onde eu
declaro o datasource e o persistence unit?

Muito obrigado,

Marques

Você tem que configurar tanto o persistence.xml quanto o components.xml para funcionar e criar um seam managed context.
 
persistence.xml fica mais ou menos como:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Persistence deployment descriptor for dev profile -->
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
             version="1.0">
            
   <persistence-unit name="mps-arquitetura">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <jta-data-source>java:/PostgresTesteDS</jta-data-source>
      <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
         <!-- property name="hibernate.hbm2ddl.auto" value="update"/ -->
         <property name="hibernate.show_sql" value="true"/>
         <property name="hibernate.format_sql" value="true"/>
         <property name="jboss.entity.manager.factory.jndi.name" value="java:/teste-arquiteturaEntityManagerFactory"/>
      </properties>
   </persistence-unit>
   
</persistence>
 
Components.xml:
 
Adicione a linha:
<persistence:managed-persistence-context name="entityManager" auto-create="true"
                      persistence-unit-jndi-name="java:/teste-arquiteturaEntityManagerFactory"/>

Se for JBOSS vc deve consigurar um datasource, por exemplo, um postgre-ds.xml que fica no diretório onde fica o ear (normalmente /default/)

<datasources>
    <local-tx-datasource>
        <jndi-name>PostgresTesteDS</jndi-name>
        <connection-url>jdbc:postgresql://localhost/teste</connection-url>
        <driver-class>org.postgresql.Driver</driver-class>
        <user-name>FBI_intend_dbrest</user-name>
        <password>ueps_cia</password>
              <min-pool-size>80</min-pool-size>
           <!-- The maximum connections in a pool/sub-pool -->
              <max-pool-size>90</max-pool-size>
        <!-- sql to call when connection is created
        <new-connection-sql>some arbitrary sql</new-connection-sql>
        -->
        <!-- sql to call on an existing pooled connection when it is obtained from pool
        <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
        -->
    </local-tx-datasource>
</datasources>

Pode ser no próprio persistence.xml, dentro da tag properties:

            <property name="hibernate.connection.driver_class" value="<Driver>" />
            <property name="hibernate.connection.username" value="usuario" />
            <property name="hibernate.connection.password" value="senha" />
            <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/<NOME_DO_BANCO> />

Tenta fazer rodar pelo persistence com o o Tiago Silva falou acima. Depois você pode tentar configurar o datasource do tomcat via context.xml ou server.xml
Atenciosamente,

Coloquei um exemplo de uma APP Seam + JbossWS mais voltado a minha realidade disponível para download.

É o meu workspace eclipse.

https://189.10.81.186:8443/infosolo.rar (workspace eclipse)

https://189.10.81.186:8443/teste.backup (banco de dados postgresql - modelo usado pela app, postgresql 8.4.x)

Precisa somente do jdk5 e jboss 4.2.3 e seam 2.1.2.
