Problemas com Datasource e Tomcat 7

Assuntos Gerais
#1

Olá Pessoal,

Estou configurando um datasource no tomcat 7 e acredito que fiz tudo certo vejam:

server.xml

<b>Resource incluido no GlobalNamingResources</b>
&lt;Resource name="jdbc/devtecDS" auth="Container"
          type="javax.sql.DataSource" driverClassName="org.postgresql.Driver"
          url="jdbc:postgresql://localhost:5432/banco"
          username="yyyyy" password="xxxxx" maxActive="20" maxIdle="10" maxWait="-1"/&gt;

web.xml

       &lt;resource-ref&gt;
		&lt;description&gt;DB Connection&lt;/description&gt;
		&lt;res-ref-name&gt;jdbc/devtecDS&lt;/res-ref-name&gt;
		&lt;res-type&gt;javax.sql.DataSource&lt;/res-type&gt;
		&lt;res-auth&gt;Container&lt;/res-auth&gt;
	&lt;/resource-ref&gt;

Código

     Context initialContext = new InitialContext();
     DataSource ds = (DataSource) initialContext.lookup("java:/comp/env/" + dataSourceName);
     return ds.getConnection();

Vejam o sysout do ds.getClass e ds.toString()

class org.apache.tomcat.dbcp.dbcp.BasicDataSource
org.apache.tomcat.dbcp.dbcp.BasicDataSource@306dbdc9

Esse código faz o lookup do Datasource mas quando tento obter uma conexão um erro é lançado:

#2

parece que o tomcat 7 ainda nao está totalmente estável

veja se eh algum bug não reportado

#3

Sim acredito que seja um bug porque testei essa mesma configuração no tomcat 6 e deu certo.

Vou esperar o pessoal do apache corrigir o problema.
