I am making a web application (E-commerce), which is the final work of the web discipline, only need to save the request in the bank but is giving an error that I can not solve. I searched, but I couldn’t find anything related.
<div class="container" align="center">
<a href="<c:url value="/pedido/pedidoFim" />" class="btn btn-success" >CONTINUAR</a><br></br>
</div>
When I click continue, it is directing me to the method in the controller that should save the request in the database. It follows method:
@Path(value = { "/pedidoFim" })
public void pedidoFim() {
Pedido pedido = new Pedido();
pedido.setCliente(clienteLogado.getCliente());
Date hoje = new Date();
pedido.setDataPedido(hoje);
pedido.setDataAlteracao(hoje);
pedido.setSituacaoPedido(1);
pedido.setTipoPagamento(1);
pedido.setValorFrete(Double.parseDouble(carrinhoLogado.getValorFrete()));
pedido.setValorTotal(Double.parseDouble(carrinhoLogado.getValorTotalPedido()));
System.out.println(pedido);
pedidoRepository.insert(pedido);
for(PedidoItem itens : carrinhoLogado.getItens()){
itens = new PedidoItem();
itens.setPedido(pedido);
itens.setProduto(itens.getProduto());
itens.setQuantidade(itens.getQuantidade());
itens.setValor(itens.getValor());
pedidoItemRepository.insert(itens);
}
result.redirectTo(PedidoController.class).pedido();
}
But you’re making this mistake:

Ever tried to make
@Path("/pedidoFim")instead of@Path(value = { "/pedidoFim" })?– igventurelli
Yes, but the same error occurs. And in the rest of the work, I use the same @Path(value = { "-----------" }) template to access the pages and run what’s inside them

I managed to resolve was giving this error because it missed the customer’s Inject. Thanks.
