Problema com Netbeans + Glassfish

15/02/2017

Ol�, tudo bem?

Estou acompanhando o curso [url:descricao=Construindo uma aplica��o completa com JavaEE]https://www.devmedia.com.br/curso/curso-de-java-ee-construa-uma-aplicacao-completa-java-ee/403[/url], fazendo algumas modifica��es em cima do que est� sendo ensinado (PostgreSQL e Hibernate com anota��es JPA).

Embora tenha sido mostrado como configurar a infraestrutura da aplica��o, fiz o mesmo passo, por�m, quando vou rodar um teste unit�rio, recebo a mensagem:

Caused by: org.apache.derby.client.am.DisconnectException: java.net.ConnectException : Erro ao conectar no servidor 'localhost' porta '1527'. Recebida a mensagem: 'Conex�o recusada (Connection refused)'.

Meu persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
  <persistence-unit name="BugTrackerEE-ejbPU" transaction-type="JTA">

            <property name="c3p0.max_size" value="30"/>
            <property name="c3p0.max_statments" value="10"/>
            <property name="c3p0.min_size" value="5"/>
            <property name="c3p0.timeout" value="120"/>
            <!-- hibernate  -->
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
            <property name="hibernate.show_sql" value="true"/>
            <property name="hibernate.format_sql" value="true"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>
        </properties>
  </persistence-unit>
</persistence>

Algu�m poderia me auxiliar e dizer o que esqueci de configurar na persist�ncia?

Mexe aqui e acol�, agora meu problema � s� de n�o encontrar a unidade de persist�ncia.

	
Exception while preparing the app : Invalid resource : jdbc/bugtrackerpool__pm
com.sun.appserv.connectors.internal.api.ConnectorRuntimeException: Invalid resource : jdbc/bugtrackerpool__pm

[url:descricao=Nesse f�rum]http://www.guj.com.br/t/invalid-resource-weshare--pm/85953/5[/url] tem a solu��o, por�m, quando tento criar o resource pelo glassfish, retorna o erro:

HTTP Status 500 - Internal Server Error
type Exception report
messageInternal Server Error
descriptionThe server encountered an internal error that prevented it from fulfilling this request.

java.lang.IllegalStateException: getOutputStream() has already been called for this response
note The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 4.1.1 logs.

No aguardo de uma alma caridosa que saiba como resolver :)
