JPA + Datasource

Boa noite pessoal,

Criei um projeto JPA no NetBeans, configurei tudo certinho, porem na hora de fazer uma inserção na base, ele da o seguinte erro:

Isso tem alguma coisa haver com aquele JNDI? Coloquei qualquer coisa nele quando adicionei uma fonte de dados ao persistence.xml…

Se for, o que é esse cara? Como configuro?

Obrigado.

Meu persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" 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">
  <persistence-unit name="ProjetoWebPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <non-jta-data-source>web</non-jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
      <property name="hibernate.connection.username" value="root"/>
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
      <property name="hibernate.connection.password" value=""/>
      <property name="hibernate.connection.url" value="jdbc:mysql://localhost/web"/>
      <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>
    </properties>
  </persistence-unit>
</persistence>

Desde já obrigado.
