pessoal tenho o seguinte persistence.xml
<?xml version="1.0" encoding="UTF-8"?>

<properties>
<property name="toplink.jdbc.user" value="postgres"/>
<property name="toplink.jdbc.password" value="dna44100"/>

<property name="toplink.jdbc.driver" value="org.postgresql.Driver"/>
</properties>
</persistence-unit>
</persistence>
e chamo ele assim:
emf = Persistence.createEntityManagerFactory("CaixaNovoPU");
return emf.createEntityManager();
porem eu li q o createEntityManagerFactory recebe um Map que seria alguns parametros adicionais e caso esse parametro ja existe… ele sobrescreve o mesmo… porem eu tentei o seguinte:
[code]Properties prop = new Properties();
prop.setProperty(“toplink.jdbc.url”, “jdbc:postgresql://10.0.0.111:5432/db_dnaso”);
emf = Persistence.createEntityManagerFactory("CaixaNovoPU",prop);
return emf.createEntityManager();[/code]
e nao deu certo. .eu nao consigo mudar ali o servidor q ele vai buscar o DB… alguem sabe como eu posso fazer isso?? pois o meu persistence.xml esta dentro do meu arquivo .jar, entao qdo iniciar a minha aplicacao eu vou no diretorio do meu .jar e nao consigo mexer em tempo de execucao, logo se eu deixar um arquivo properties fora do meu .jar sempre q iniciar a aplicacao eu busco nele o ip do servidor
segue o texto o createEntityManagerFactory
