How to open all the downloading douments in browser

[Chandra Men]

Hi,

My reqquirement is opening all the requested(httpRequest) documents within the browser and not in the new tab. My application is supporting to the all MIME types but its initailly finding the local installed software then its opened.

The problem is required software is not available then its throws exception. See the below code and point me in the right direction.

Any help will be greatly appreciated. Thank you for your help.

ServletOutputStream out = response.getOutputStream();
		FileInputStream fis = null;
		ServletInputStream in = null;
		String mimeType = null;
		Session session = null;
			
		List<String> mimeTypeList = Arrays.asList("application/pdf",
				"application/octet-stream", "application/msword",
				"application/rtf", "application/x-visio",
				"text/comma-separated-values", "application/vnd.ms-excel",
				"application/x-msg", "text/html", "application/xml",
				"application/plain", "text/plain", "image/gif", "image/jpeg",
				"image/png", "image/tiff", "image/bmp");

		try {
			session = HibernateSessionFactory.getSessionFactory().openSession();
			session.beginTransaction();
			
			String id = request.getParameter("documentID");
					
			String hqlQuery = "from Documentinstance as doc where doc.documentInstanceId="+id;
			Query dmsQuery = session.createQuery(hqlQuery);
			Object obj = dmsQuery.uniqueResult();
			Documentinstance docInstance = (Documentinstance) obj;

			String relPath = "D:" + docInstance.getDocRelativePath()
					+ docInstance.getDocName() + "."
					+ docInstance.getDocContentType();

			File file = new File(relPath);
			fis = new FileInputStream(file);
			MimetypesFileTypeMap mimeTypesMap = new MimetypesFileTypeMap();
			mimeType = mimeTypesMap.getContentType(file);
			String fileName = file.getName();

			if (mimeTypeList.contains(mimeType)) {
				response.setContentType(mimeType);
				System.out.println("MIME : "+mimeType);
			}
			response.setContentLength((int) file.length());
			response.setHeader("Content-Disposition", "attachment;filename=\""
					+ fileName + "\"");

			int readBytes = 0;
			while ((readBytes = fis.read()) != -1) {
				out.write(readBytes);
			}
		
				
		} catch (Exception e) {
		
		}
