HERE IS WHERE TOMCAT SHOWS THE ERROR.
The bean name is dica. I made a test, putting a line with a condition like
this:
if (dica == null) // NEW !
System.out.println("valorrr"+dica.getteDescricaodica());
and this condition is true when this app runs!!! Why?
__ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ___
__ ____ ____ ____ ___
System.out.println(" passei no getatribute " + autorizacao);
for(int i = 0;pega.hasNext()&&i<10;i++)
{
dica = (Dica)pega.next();
int limite = 0;
if (dica == null) // NEW !
System.out.println("valorrr"+dica.getteDescricaodica());
if (dica.getteDescricaodica().length() <= 40 )
limite = dica.getteDescricaodica().length();
else
limite = 40;
if (limite == 0) limite = 1;
if ( autorizacao == null )
