Jasper download dialog not appear

[Fra83]

Hello,
I have a problem with my java web application (WebLogic 10.3.5, Spring 3.1 and Jasper 5.0.1) I want to export an excel report, but at the end of operation, jasper download dialog not appear. In Tomcat AS everything works, but not in WebLogic.

Jsp code with export button:

<a title="Export" href="javascript:window.location.replace('<%=path %>/admin/export.com');">Export</a>[/code]

Spring MVC Controller:

@RequestMapping("/export.com")public ModelAndView exportAction(@ModelAttribute("model") UserModel model, HttpServletRequest request) throws Exception{    SearchBean searchForm = model.getSearchForm();    Map<String,Object> parameterMap = new HashMap<String,Object>();    List<User>usersList = iReportService.getUsers(searchForm,null).getResults();    JRDataSource JRdataSource = new JRBeanCollectionDataSource(usersList);    parameterMap.put("datasource", JRdataSource);    return new ModelAndView("XlsUserReport",parameterMap);}[/code]

In the same spring context I use two different resolver (UrlBasedViewResolver and XmlViewResolver) so maybe this can create problems.
As I said, in tomcat AS, jasper download dialog appear, but when I deploy my web application in WebLogic, after export click a blank page appear (the URL is .../export.com)
