Hola. Estoy intentando hacer una aplicación web y para ello uso tomee y persistencia EJB y me da error al intentar obtener el EntityManager porque no encuentra el JDBC.
Mi fichero tomee.xml es el siguiente:
<?xml version="1.0" encoding="UTF-8"?>
<tomee>
  <!-- see http://tomee.apache.org/containers-and-resources.html -->

  <!-- activate next line to be able to deploy applications in apps -->
  <!-- <Deployments dir="apps" /> -->
   <Resource id="TestDS" type="DataSource">
     JdbcDriver com.mysql.jdbc.Driver
     JdbcUrl jdbc:mysql://localhost:3306/databaseName
     UserName user
     Password 123
     JtaManaged true
   </Resource>
</tomee>
Y el fichero persistence.xml el siguiente:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" 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_2_1.xsd">
        <persistence-unit name="TestDSunit" transaction-type="JTA">
          <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
          <jta-data-source>TestDS</jta-data-source>
          <class>dao.User</class>
     <properties>
            <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)"/>
          </properties>
        </persistence-unit>
</persistence>
He probado poniendo en jta-data-source las siguientes opciones
java:openejb/Resource/TestDS
java:comp/env/TestDS
java/TestDS
Y siempre me da el mismo error:
<openjpa-2.4.0-nonfinal-1598334-r422266:1599166 fatal user error> org.apache.openjpa.persistence.ArgumentException: The persistence provider is attempting to use properties in the persistence.xml file to resolve the data source. A Java Database Connectivity (JDBC) driver or data source class name must be specified in the openjpa.ConnectionDriverName or javax.persistence.jdbc.driver property. The following properties are available in the configuration: "org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl@fdaf18ee".
Y es que ya no sé como solucionar para que lo pueda localizar, ¿alguna ayuda? gracias

¿Conocéis algún termómetro que pueda funcionar en JSF?

Soy nueva con TomEE, me he creado un proyecto web vacío, lo he ejecutado con el servidor TomEE y me sale la siguiente excepción:

Soy nueva con TomEE, siguiendo este tutorial: http://jaxenter.com/getting-started-with-apache-tomee-105824.html he intentado implementarlo en mi proyecto, pero me da la siguiente excepción:

No entiendo qué es lo que puede fallar.



I delete The Servers folder and I configure again to run with TomEE, I get the following exception:

The problem is with the xalan-2.7.1.jar library. I do not know how to make it works with TomEE.

Mod: No hacer doble post. Utilizar etiquetas [code][/code] para publicar output.

Gracias, es verdad, sólo es necesario el import:
import java.awt.dnd.*;

¿De dónde me puedo descargar la API de Java llamada Drag and Drop?

Muchas gracias

Dentro de un programa en java, ¿cómo podría ejecutar un comando, por ejemplo reset?

Tienes razón, tendría que instanciarlo antes.
Lo que quería hacer array1=array2.

Muchas gracias.

Al ejecutar este codigo me salta una excepción NullPointerException:

      for (int i = 0; i <= array1.length; i++) {
         array2 = array1;
      }

¿Por qué?
