Olá, não sei por que eu não estou conseguindo gravar no meu Banco de Dados… esse é o código que eu estou utilizando:
private void salvarButtonActionPerformed(java.awt.event.ActionEvent evt) {
try
{
entityManager.getTransaction().commit();
entityManager.getTransaction().begin();
}
catch (RollbackException rex)
{
rex.printStackTrace();
entityManager.getTransaction().begin();
List<br.com.pig.bean.CategoriaProjeto> merged = new ArrayList <br.com.pig.bean.CategoriaProjeto>(list.size());
for (br.com.pig.bean.CategoriaProjeto cp : list)
{
merged.add(entityManager.merge(cp));
}
list.clear();
list.addAll(merged);
}
}
Já o reescrevi, para essa forma, mas tbm não alterou em nada
private void salvarButtonActionPerformed(java.awt.event.ActionEvent evt) {
try
{
entityManager.getTransaction().begin();
List<br.com.pig.bean.CategoriaProjeto> merged = new ArrayList <br.com.pig.bean.CategoriaProjeto>(list.size());
for (br.com.pig.bean.CategoriaProjeto cp : list)
{
merged.add(entityManager.merge(cp));
}
list.clear();
list.addAll(merged);
entityManager.getTransaction().commit();
}
catch (RollbackException rex)
{
rex.printStackTrace();
entityManager.getTransaction().rollback();
}
}
O erro que ele me dá, é esse:
Exception in thread “AWT-EventQueue-0” java.lang.IllegalStateException:
