Pessoal, usando este fonte:

Map parameters = new HashMap();
									parameters.put("Filial", valor);
																					
									try{
										JasperFillManager.fillReportToFile("C:\classic.jasper", parameters);
										JasperExportManager.exportReportToPdfFile("C:\classic.jrprint");
										//JasperRunManager.runReportToPdf("C:\classic.jasper", parameters);
										JasperViewer.viewReport("classic.pdf",false);
									}catch (JRException e1){
										e1.printStackTrace();
									}

Deu esse minúsculo erro que não consigo decifrar:

Alterando o fonte para:

try{
										
										Map parameters = new HashMap();
										parameters.put("Filial", valor);
										//System.out.println(valor);
										JasperRunManager.runReportToHtmlFile("C:\classic.jasper", parameters);
										//JasperFillManager.fillReportToFile("C:\classic.jasper", parameters);
										//JasperExportManager.exportReportToPdfFile("C:\classic.jrprint");
										JasperViewer.viewReport("C:\classic.html",false);
										
									}catch (JRException e1){
										e1.printStackTrace();
									}

Dá o seguinte erro:

paulinhohd:
Alterando o fonte para:
JasperRunManager.runReportToHtmlFile("C:\classic.jasper", parameters);

Esse método retorna a String do caminho do arquivo criado.

Tenta fazer assim:

String filePath = JasperRunManager.runReportToHtmlFile("C:\classic.jasper", parameters);
JasperViewer.viewReport(filePath,false);

PS: Uma olhada na API e voce veria isso.

Colocando exatamente como falou, veja o erro:
