JSP Error : Attribute qualified names must be unique within an element
Today I updated an old Spring MVC application to Apache Tomcat 7 and some other newer jars and, when I started it, I get this error:
SEVERE: Servlet.service() for servlet [mvc-dispatcher] in context with path [/CG] threw exception [/WEB-INF/view/main.jsp (line: 2, column: 0) /WEB-INF/view/include.jsp (line: 3, column: 75) Attribute qualified names must be unique within an element] with root cause org.apache.jasper.JasperException: /WEB-INF/view/main.jsp (line: 2, column: 0) /WEB-INF/view/include.jsp (line: 3, column: 75) Attribute qualified names must be unique within an element |
After some search i find out that using single attribute multiple time in a single tag throw this error(it works with no problem in previous version!!!)
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %> |
I removed the duplicated “prefix” tag and everything worked fine! (…ehm… everything? Of course not… but this exception has been fixed)

The Last Lecture – Randy Pausch
The most motivational video I’ve ever seen.
Debug content model in Alfresco
When you need to customize Alfresco content model, not always everything works fine so, it’s necessary to find a way to check if your model is correct or not. It’s possible to use the built-in Get Class Definitions webscript to debug. Basically, you can use this webscript to see if an expected content type exists on Alfresco or not. You can also use this webscript to see if an expected content type exists on Alfresco or not. All you have to do is to call the webscript with your class name which in this case myroot:mycontent for me.
http://localhost:8086/alfresco/service/api/classes/myroot_mycontent |
Or you can call the same webscript without a class name, in this case webscript will dump every content type that exists on Alfresco.
The response will be something like that:

Analyzie MS Exchange log
Sometime happens to receive some interesting requests from the business like “Hey man, take a look if there are some strange access to our web mail”. This tool it’s really useful for this kind of task: Log Parser Studio
It requires (in this case) a IISW3CLOG and a simple query like that:
SELECT TOP 20 cs-username AS UserID, cs(User-Agent) AS Application, cs-uri-stem AS Vdir, c-ip AS CLIENT, cs-method, COUNT(*) FROM '[LOGFILEPATH]' WHERE cs-uri-stem LIKE '%OWA%' GROUP BY UserID, Application, Vdir, Client, cs-method ORDER BY COUNT(*) DESC |
That’s all!
How to download PDF file from url on MVC controller

@RequestMapping(value="/viewAttach", method = RequestMethod.GET) public ModelAndView viewAttach(@RequestParam(value="article_id", required = true) String article_ref, HttpSession session, HttpServletResponse response) { /* *** Remember to check if Session still valid *** */ try { URL url = new URL(remoteURL); response.setHeader("Content-disposition", "attachment;filename=" + filename); //Set the mime type for the response response.setContentType("application/pdf"); // URLConnection connection = url.openConnection(); InputStream is = url.openStream(); BufferedOutputStream outs = new BufferedOutputStream(response.getOutputStream()); int len; byte[] buf = new byte[1024]; while ( (len = is.read(buf)) > 0 ) { outs.write(buf, 0, len); } outs.close(); } catch (MalformedURLException e) { logger.error("Error ModelAndView.viewMain - MalformedURLException : " + e.toString() + " -- " + e.getStackTrace()[0].toString()); return null; } catch (IOException e) { logger.error("Error ModelAndView.viewMain - IOException : " + e.toString() + " -- " + e.getStackTrace()[0].toString()); return null; } return null; } |

Understanding Credit crunches
Credit crunches are usually considered to be an extension of recessions. A credit crunch makes it nearly impossible for companies to borrow because lenders are scared of bankruptcies or defaults, which results in higher rates. The consequence is a prolonged recession (or slower recovery), which occurs as a result of the shrinking credit supply.
