java.lang.Classnotfoundexception: javax.persistence.Persistence

Question

I am in error when using Entitymanagerfactory, is a web project with Hibernate + JPA

This is the mistake:

java.lang.Classnotfoundexception: javax.persistence.Persistence at org.apache.Catalina.loader.Webappclassloaderbase.loadClass(Webappclassloaderbase.java:1407) at org.apache.Catalina.loader.Webappclassloaderbase.loadClass(Webappclassloaderbase.java:1215) at br.com.Antony.util.Jpautil.(Jpautil.java:9) at br.com.Antony.controller.Cadastrousuario.doPost(Cadastrousuario.java:47) at javax.servlet.http.HttpServlet.service(Httpservlet.java:681) at javax.servlet.http.HttpServlet.service(Httpservlet.java:764) at org.apache.Applicationfilterchain.internalDoFilter(Applicationfilterchain.java:228) at org.apache.Catalina.core.Applicationfilterchain.doFilter(Applicationfilterchain.java:163) at org.apache.Tomcat.websocket.server.WsFilter.doFilter(Wsfilter.java:53) at org.apache.Applicationfilterchain.internalDoFilter(Applicationfilterchain.java:190) at org.apache.Catalina.core.Applicationfilterchain.doFilter(Applicationfilterchain.java:163) at org.apache.Catalina.core.Standardwrappervalve.invoke(Standardwrappervalve.java:202) at org.apache.Catalina.core.Standardcontextvalve.invoke(Standardcontextvalve.java:97) at org.apache.Catalina.authenticator.Authenticatorbase.invoke(Authenticatorbase.java:542) at org.apache.Catalina.core.Standardhostvalve.invoke(Standardhostvalve.java:143) at org.apache.Catalina.valves.Errorreportvalve.invoke(Errorreportvalve.java:92) at org.apache.Catalina.valves.Abstractaccesslogvalve.invoke(Abstractaccesslogvalve.java:687) at org.apache.Catalina.core.Standardenginevalve.invoke(Standardenginevalve.java:78) at org.apache.Catalina.connector.Coyoteadapter.service(Coyoteadapter.java:357) at org.apache.Coyote.http11.Http11processor.service(Http11processor.java:382) at org.apache.Coyote.AbstractProcessorLight.process(Abstractprocessorlight.java:65) at org.apache.Coyote.Abstractprotocol$Connectionhandler.process(Abstractprotocol.java:893) at org.apache.Tomcat.util.net.Nioendpoint$Socketprocessor.doRun(Nioendpoint.java:1723) at org.apache.Tomcat.util.net.SocketProcessorBase.run(Socketprocessorbase.java:49) at java.base/java.util.Concurrent.ThreadPoolExecutor.runWorker(Threadpoolexecutor.java:1128) at java.base/java.util.Concurrent.Threadpoolexecutor$Worker.run(Threadpoolexecutor.java:628) at org.apache.Tomcat.util.threads.Taskthread$Wrappingrunnable.run(Taskthread.java:61) at java.base/java.lang.Thread.run(Thread.java:834)

This is my Jpautil class:

public class JPAUtil {

    private static final EntityManagerFactory FACTORY = Persistence.createEntityManagerFactory("desafio");      public static EntityManager getEntityManager() {

Return FACTORY.createEntityManager(); } }

My Servlet:

@WebServlet("/cadastrousuario")
public class CadastroUsuario extends HttpServlet {

    private static final long serialVersionUID = 1L;

    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        PrintWriter out = response.getWriter();

        Usuario usuario = new Usuario();
        usuario.setNome(request.getParameter("nome"));
        usuario.setEmail(request.getParameter("email"));
        usuario.setSenha(request.getParameter("senha"));

        Telefone telefone1 = new Telefone();
        // telefone1.setDdd(Integer.parseInt(request.getParameter("dddTelefone1")));
        telefone1.setNumero(request.getParameter("numeroTelefone1"));
        telefone1.setTipo(request.getParameter("tipoTelefone1"));

        Telefone telefone2 = new Telefone();
        // telefone2.setDdd(Integer.parseInt(request.getParameter("dddTelefone2")));
        telefone2.setNumero(request.getParameter("numeroTelefone2"));
        telefone2.setTipo(request.getParameter("tipoTelefone2"));

        List<Telefone> telefones = Arrays.asList(telefone1, telefone2);
        usuario.setTelefones(telefones);

        EntityManager entityManager = JPAUtil.getEntityManager();

        UsuarioDao dao = new UsuarioDao(entityManager);

        try {
            entityManager.getTransaction().begin();
            dao.cadastrar(usuario);
            entityManager.getTransaction().commit();
            entityManager.close();
            out.println("Cadastrado com Sucesso !!");
        } catch (Exception e) {
            out.println("Erro ao Cadastrar !!" + e.getMessage());
        }

    }
}
