Gerar Relatório com JasperReport

Boa tarde.

Estou pesquisando alguns fóruns e tópicos pela internet para tentar entender o funcionamento do JasperReport. Não tive sucesso! Todos os métodos que encontrei utilizam um resource como parâmetro juntamento com o InputStream do arquivo .jarper e o Map.

O que eu gostaria de fazer:

                        HttpServletRequest request = ServletActionContext.getRequest();
			String numeroPedido = request.getParameter("numero");
			
			pedido = pedidoServicoRepository.getById(Integer.parseInt(numeroPedido));
			
			Map<String, Object> parametros = new HashMap<String, Object>();
			
			parametros.put("numero_pedido", pedido.getNumeroPedido());
			parametros.put("permissionario", pedido.getOcupacao().getPermissionario().toString());
			parametros.put("pnr", pedido.getOcupacao().getPnr().toString());
			parametros.put("data_solicitacao", pedido.getDataPedido().toString());
			parametros.put("situacao_pedido", pedido.getSituacaoPedidoServico().getDescricao());
			parametros.put("prioridade_pedido", pedido.getPrioridadePedidoServico().getDescricao());
			parametros.put("email", pedido.getEmail());
			parametros.put("fone", pedido.getFone());
			parametros.put("descricao_pedido", pedido.getDescricaoPedido());
			parametros.put("retorno_pedido", pedido.getRetornoPedido());

E agora gostaria de compilar o jrxml que contém todos os campos declarados no Map:

Como posso gerar um pdf com isso?

Isso é uma aplicação web e também estava tendo problemas na localização do arquivos jrxml/jasper dentro do WebContent.

Agradeço a ajuda.
