Problema estranho com Hibernate

Assuntos Gerais Agile
#1

Olá amigos, estou com um problemão. Quando testo minha aplicação web local, em minha máquina, tudo funciona muito bem, porém quando posto no meu servidor (com SO Linux) o arquivo .WAR da minha aplicação e tento rodar o seguinte erro acontece:

javax.servlet.ServletException
org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:545)
org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:486)
org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482)
org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

root cause

Mais estranho ainda é que nos arquivos de log do tomcat não encontro erro algum. Preciso muito de ajuda.

Valew!

poste o codigo de
br.com.wwwt.animaltrace.util.HibernateUtility.getSession(HibernateUtility.java:40)

e o seu hibernate.cfg.xml

aih podemos ajudar…

Valeu

#3

O erro pode estar no arquivo de configuração do Hibernate (hibernate.cfg.xml ), poste ele para vermos como ele está!

O código do HibernateUtility.java é:

[color=“darkred”]
public class HibernateUtility {
private static SessionFactory factory;
static {
//Bloco estático que inicializa o Hibernate
try {
factory = new Configuration().configure().buildSessionFactory();
} catch (Exception e) {
e.printStackTrace();
factory = null;
}
}
public static Session getSession() {
return factory.openSession(); << (linha 40)
}
}
[/color]

e do hibernate.cfg.xml é:

[color=“darkred”]
<hibernate-configuration>
<session-factory>

	&lt;property 
		name="hibernate.dialect"&gt;
