How to use printwriter in Liferay Render Response

[Pradeep Kumar Sharma, modificado hace 11 años.]

Hi,

I would like to get some help regarding this issue mentioned below.



I have a existing code here and I am trying to bring this SpringMVC application to SpringMVC portlet environment. Any help will be really appreciated.

private void sendOutput(HttpServletRequest request,
HttpServletResponse response, String serverPath, ReportInfo rptInfo)
throws IOException, ServletException {

ReportWriter rw = new ReportWriter(response.getOutputStream());

String metric = request.getParameter("metric");
String outputType = request.getParameter("outputType");
try {

if (metric != null) {
rw.writeHtmlDetail(rptInfo, metric);
} else {
// Check and set output document type.
if (PDF.equals(outputType)) {
/* This updates the HTML header so it must be the first thing output. */
response.setContentType(PDF_CONTENT_TYPE);
response.setHeader("Content-Disposition",
" inline; filename=\"" + FILENAME + ".pdf\"");

// Format and output the report results ...
rw.writePdf(rptInfo);
return;
} else if (EXCEL.equals(outputType)) {
/* This updates the HTML header so it must be the first thing output. */
response.setContentType(EXCEL_CONTENT_TYPE);
response.setHeader("Content-Disposition",
" inline; filename=\"" + FILENAME + ".xls\"");
rw.writeExcel(rptInfo);
return;
} else {
// else HTML ...
// Format and output the report results ...
rw.writeHtml(rptInfo, serverPath);
}
}
} catch (Exception ex) {
throw new ServletException(ex);
}

How should I write a new controller to make this working.

Thank You !
Pradeep

A portlet is different than a servlet. In a servlet, you can generate the whole html that will be rendered in a page.

A portlet, however, is responsible for generating a fragment of the whole aggregated page.

To do this in a portlet, you build it as a resource request (the resource request gets to return the whole thing).

Thank you David. This helps but need a little more info regarding, how I can make Action using this code:

Note: Hope this value= "/viewDashboard" will not work in Liferay of URL, How I can define this output URL in Liferay

@RequestMapping(value = "/viewDashboard", method = RequestMethod.GET)
// Hope this value= "/viewDashboard" will not work in Liferay of URL, How I can define this output URL in Liferay
public void viewDashboard(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException, DbSqlException {
logger.info("In ComplusController.viewDashboard");
String serverPath = getThisURL(request);

ReportInfo rptInfo = getReportInfo(request);
logger.info("In ComplusController>> Server Path", serverPath);
sendOutput(request, response, serverPath, rptInfo);
}
private static List<String> getSystems(Clients clients) {
List<String> systems = clients.getSystems();
return systems;
}
private static List<String> getMgmtCodes(Clients clients) {
List<String> mgmtCodes = new ArrayList<String>();
List<Client> clientList = clients.getClients();

for (Iterator<Client> it = clientList.iterator(); it.hasNext();) {
Client client = it.next();
mgmtCodes.add(client.getMgmtCode());
}
return mgmtCodes;
}

Im my ResourceMapping, If any help will be really appreciated.

Thanks You !

This is servlet code. None of it is going to work as a portlet.

File objects would be returned as resource requests. The other code is cut off, so I'm not sure what the getSystems() and getMgmtCodes() is used for.

[Hitoshi Ozawa, modificado hace 11 años.]

Look at the following page to see how SpringMVC portlet handles Requests.

Thank you Davis and Hitoshi for quick response.

I made it working putting mock value in the JSP screen. Using this ResourceMapping, How I can store the user input and pass to the service. If any help will be really appreciated.

If any of us can suggest something regarding this will be wonderful.

HI Pradeep Kumar Badhai,

Use direct ServeResource Response to set the content type and headers.

response.setContentType("application/pdf");
response.setProperty(com.liferay.portal.kernel.servlet.HttpHeaders.CONTENT_DISPOSITION,"attachement;filename=filename");

OutputStream os = response.getPortletOutputStream();

need not use HttpServletResponce any where. directly use all serveResourseResponse and l serveResourseRequest where ever you required.
