Hi all,
I'm having problems with Tapestry and JPA together using Hibernate as the
provider. When i try to make a connection, tapestry gives me this exception:
org.apache.tapestry.BindingException Exception invoking listener method
gravar of component Home: Failure invoking listener method 'public
org.apache.tapestry.IPage site.Home.gravar()' on [EMAIL PROTECTED]:
javax/persistence/Persistence
[EMAIL PROTECTED] parameter
action, component=Home, methodName=gravar,
location=context:/WEB-INF/Home.html, line 29]
java.lang.NoClassDefFoundError javax/persistence/Persistence
code:
import javax.persistence.*;
public final class Connection {
private static EntityManagerFactory factory = null;
private static EntityManager manager = null;
private Connection(){
factory = Persistence.createEntityManagerFactory("exemplo"); //the
problem is here
manager = factory.createEntityManager();
}
...
it seems that the app cannot found the class javax.persistence.Persistence,
but the jar is on the lib directory... i don't know why he is giving me this
exception because on an non-web environment everything is doing fine. When i
switch the provider to Toplink, i can connect fine too, but my db doesn't
support it. Am i missing something? Any help will be appreciated!
