Hi Liferay,
I am using Liferay 6.1.0 ga1 jsf-portlet.(Using primefaces command-button component)
I am trying to implement download pdf file functionality on button click in this way.
<p:commandbutton actionListener="#{backingBB.DownloadPDF(obj)}" update=":form" />
public void DownloadPDF(Employee obj) throws DocumentException, FileNotFoundException, IOException
{
PortletResponse portletResponse = (PortletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
HttpServletResponse response= com.liferay.portal.util.PortalUtil.getHttpServletResponse(portletResponse);
//We must get first our context
FacesContext context = FacesContext.getCurrentInstance();
//Then we have to get the Response where to write our file
//Now we create some variables we will use for writting the file to the response
String filePath = null;
int read = 0;
byte[] bytes = new byte[1024];
String pathToTheFile="http:\\174.25.1.189:8080\html\pdf";
//Be sure to retrieve the absolute path to the file with the required method
filePath = pathToTheFile;
System.out.println("PATH "+filePath);
//Now set the content type for our response, be sure to use the best suitable content type depending on your file
//the content type presented here is ok for, lets say, text files and others (like CSVs, PDFs)
response.setContentType("application/pdf");
//This is another important attribute for the header of the response
//Here fileName, is a String with the name that you will suggest as a name to save as
//I use the same name as it is stored in the file system of the server.
String fileName="Aryan sds_07_007.pdf";
response.setHeader("Content-Disposition", "attachment;filename=\"" +
fileName + "\"");
//Streams we will use to read, write the file bytes to our response
FileInputStream fis = null;
ServletOutputStream os = null;
//First we load the file in our InputStream
try {
fis = new FileInputStream(new File(filePath,fileName));
os = response.getOutputStream();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//While there are still bytes in the file, read them and write them to our OutputStream
/* try {
while((read = fis.read(bytes)) != -1){
os.write(bytes,0,read);
}
os.flush();
os.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}*/
//Clean resources
//This option isn't quite necessary, It worked for me with or without it
FacesContext.getCurrentInstance().responseComplete();
//End of the method
}
But I am getting IOException as
java.io.FileNotFoundException: http:\174.25.1.189:8080\html\pdf\Aryan sds_07_007.pdf (The filename, directory name, or volume label syntax is incorrect)
If I try to enter this url in browser window(from client machine) (above url is my server url & I am trying to download this file from any client machine)
it opens successfully.
So what I am missing in my path ?
Thanks,
Aryan sds
