Please try to upgrade to the latest AWPr version 1.5.0 and let us know how that goes.<br/> <br/> Thanks. Thanks Alaaedin, <br/> I still get junk character for Content Retrieval (getContent) GET /alfresco/service/api/node/content{property}/{store_type}/{store_id}/{id}?a={attach?} using AWPr 1.5<br/> <br/> I tried modifying doView of JSPPortlet with following COde<br/> public void doView(RenderRequest req, RenderResponse res) throws IOException, PortletException {<br/> WebscriptPreferences wsprefs = (WebscriptPreferences) req.getPortletSession().getAttribute(<br/> Constants.SESSION_ATTRIBUTE_WSPREFS);<br/> if (wsprefs == null) {<br/> wsprefs = new WebscriptPreferences();<br/> wsprefs.readPortletPreferences(req);<br/> <br/> req.getPortletSession().setAttribute(Constants.SESSION_ATTRIBUTE_WSPREFS, wsprefs);<br/> }<br/> <br/> if (&quot;&quot;.equals(wsprefs.getAlfrescoHost()) || &quot;&quot;.equals(wsprefs.getWebscriptUrl())<br/> || wsprefs.getAlfrescoHost() == null || wsprefs.getWebscriptUrl() == null) {<br/> include(viewJSP, req, res);<br/> } else {<br/> // Get Alfresco ticket for the user<br/> String alfTicket = getAlfrescoTicket(req, wsprefs);<br/> System.out.println(&quot;Alfresco Ticket Generated: &quot; + alfTicket);<br/> System.out.println(&quot;wsPrefs WebScriptURL sent: : &quot; + wsprefs.getWebscriptUrl());<br/> // Execute script<br/> byte[] image=executeScript(req, res, wsprefs, alfTicket);<br/> //byte[] image=(byte[])req.getAttribute(&quot;webscript-content&quot;);<br/> <br/> HttpServletResponse httpResponse = PortalUtil.getHttpServletResponse(res);<br/> httpResponse.setContentType(&quot;image/gif&quot;);<br/> <br/> javax.servlet.ServletOutputStream outputStream = httpResponse.getOutputStream();<br/> outputStream.write(image, 0, (int)image.length);<br/> outputStream.flush();<br/> //include(webscriptJSP, req, res);<br/> }<br/> Even though I set httpResponse contenttype to image/gif I still get Junk characters on portlet. When i did view source I found that the content is wrapped by div tag so I am not able to set the contenttype Please attach your webscript code so I can take a look at it.<br/> <br/> Thanks.

This is not a bug. AWPr is not meant to be used this way. Content streaming Web scripts are special since they stream binary content that must be handled differently. For binary content we must use Portlet 2.0 resource URLs and thus to achieve what you want you must do the following:<br/> <br/> - Create a new Web script in your Alfresco repository and add the following line in your FTL:<br/> <br/> &nbsp;&nbsp;&nbsp;&nbsp;&lt;img src=&quot;${url.serviceContext}/api/node/content/workspace/SpacesStore/1a4d715b-316b-4a92-9b31-8b6163e26742/ORG-CHART.gif/&gt;<br/> <br/> Note: It would be advisable to generalize the image information (storeType, storeId, Id, FileName) by getting it through Web script arguments that can be passed from AWPr using the &quot;Constant Script Parameters&quot; preference. <br/> <br/> - Next add a new AWPr portlet to your page and use your new Web script&#39;s URL ( you can call it image_viewer or something :) ).<br/> <br/> That should do it. Hope this helps. Thanks <br/> Now we are able to view images by creating new script Development Rank 0|i00e1b: Rank (Obsolete) 2275 Resolution Date Mon, 20 Jul 2009 00:00:00 +0000
