&#34;res&#34; is RenderResponse. <br /><br />public ActionForward render(ActionMapping mapping, ActionForm form,<br /> PortletConfig config, RenderRequest req, RenderResponse res)<br /> throws Exception {<br /><br /> <br /> HttpServletResponse response = PortalUtil<br /> .getHttpServletResponse(res);<br /> response.setContentType(&#34;application/vnd.ms-excel&#34;);<br /> response.setHeader(&#34;Content-Disposition&#34;,<br /> &#34;attachment;filename=&#34; + fileName);<br /> res.setContentType(&#34;application/vnd.ms-excel&#34;);<br /> res.addProperty(HttpHeaders.CONTENT_DISPOSITION,<br /> &#34;attachment; filename=&#34; + fileName);<br />}<br /><br />I set the content type in both RenderResponse and HttpServletResponse and it worked for me

Hey my question may be silly but I am doing this for the first time.<br /><br />What is res in the below line ?<br />HttpServletResponse response = PortalUtil.getHttpServletResponse(res);<br /><br />And do we need to set the content type two times using response and res ?<br />response.setContentType(&#34;application/vnd.ms-excel&#34;);<br />response.setHeader(&#34;Content-Disposition&#34;, &#34;attachment;filename=&#34; + fileName);<br />res.setContentType(&#34;application/vnd.ms-excel&#34;);<br /><br />BTW Thanks !!!

I have tried with the following code which worked for me:<br /><br /><br />HttpServletResponse response = PortalUtil.getHttpServletResponse(res);<br />response.setContentType(&#34;application/vnd.ms-excel&#34;);<br />response.setHeader(&#34;Content-Disposition&#34;, &#34;attachment;filename=&#34; + fileName);<br />res.setContentType(&#34;application/vnd.ms-excel&#34;);<br />res.addProperty(HttpHeaders.CONTENT_DISPOSITION, &#34;attachment; filename=&#34; + fileName);<br /><br />try {<br /> OutputStream out = res.getPortletOutputStream();<br /> InputStream in = new FileInputStream(new File(excelPath));<br /> if (in == null) {<br /> out.close();<br /> } else {<br /> byte[] buffer = new byte[4096];<br /> int len;<br /><br /> while ((len = in.read(buffer)) != -1) {<br /> out.write(buffer, 0, len);<br /> }<br /><br /> out.flush();<br /> in.close();<br /> out.close();<br /> }<br /><br /> } catch (Exception ex) {<br /><br /> _log.error(ex);<br /> }

Hello,<br />I developed a custom portlet for Liferay 6 where Clicking on a link should download an excel file.<br />I use response.setContentType (&#34;application/excel&#34;).<br />Below is the code snippet:<br /><br />ServletOutputStream outs = null;<br />File f = new File (&#34;/Users/Sraddhanjali/desktop/sony_bmg.xlsx&#34;);<br />response.reset();<br />response.setContentType (&#34;application/excel&#34;);<br />response.flushBuffer();<br />outs = response.getOutputStream();<br /><br />But I am getting the following error:<br /><br />java.lang.IllegalStateException: Cannot obtain OutputStream because Writer is already in use<br />at com.liferay.portlet.MimeResponseImpl.getPortletOutputStream(MimeResponseImpl.java:67)<br />at com.liferay.portlet.PortletServletResponse.getOutputStream(PortletServletResponse.java:188)<br /><br />Do you have suggestions?<br /><br />Thanks in advance,<br />Sraddha
