Display pdf in browser using a rest service

Question

I am generating a pdf with japser reports and I would like to create a REST web service that will return this pdf and display it in the browser. I have already tried the code displayed here:

REST web services method to display pdf file in browser

But in this way the pdf file is downloaded. I would prefer it to be displayed in the browser first and then if the user wants he could download it later.

(sorry for the duplicate question, but as you can see the above question has not been answered... )

EDIT:

Working REST Service Code:

@GET @Path("/pdf") @Produces("application/pdf") public javax.ws.rs.core.Response getPdf() throws Exception {     File file = new File("E:\\tmp\\test.pdf");     FileInputStream fileInputStream = new FileInputStream(file);     javax.ws.rs.core.Response.ResponseBuilder responseBuilder = javax.ws.rs.core.Response.ok((Object) fileInputStream);     responseBuilder.type("application/pdf");     responseBuilder.header("Content-Disposition", "filename=test.pdf");     return responseBuilder.build(); } 

Answer 1

change

response.header("Content-Disposition",  "attachment; filename=restfile.pdf"); 

to

response.header("Content-Disposition",  "filename=restfile.pdf"); 

Answer 2

Using InputStream first we can load the file into inputstream, then pass to IOUtils.copy and use this response.header("Content-Disposition", "attachment; filename=restfile.pdf") for download, use this for preview response.setHeader("Content-disposition", " filename=" + output)

    InputStream inputStream = new FileInputStream(new File(path)); // load the file     IOUtils.copy(inputStream, response.getOutputStream());      response.setContentType("application/pdf");     response.setHeader("Content-disposition", " filename=" + output);      response.flushBuffer(); 

Return type of the method is `ResponseEntity
