Ubuntu tip: Turning Ubuntu into Kubuntu or Xubuntu - WinMatrix

    4. If you're already using Kubuntu or Xubuntu and want to enable Gnome, type "sudo apt-get install gnome-desktop"

Raible Designs | Proposed Tomcat Enhancement: Add flag to escape JSP's EL by default

  • Hello all,



    I'm working for a client that's using a proprietary Servlet/JSP-based framework that runs on Tomcat. They have their own custom JSP compiler and they're looking to move to a standard JSP compiler. One of the things their compiler supports is automatic escaping of XML in expressions. For example, ${foo} would be escaped so <body> -> &lt;body&gt;. JSP EL does not do this. It *doesn't* escape by default and instead requires you to wrap your expressions with <c:out/> if you want escaping.



    I'd like to ask what developers think about adding a flag (similar to trimSpaces in conf/web.xml) that allows users to change the escaping behavior from false to true?



    I think this is a good option to have as it allows security-conscious organizations to paranoid and escape all content by default.



    Thanks,



    Matt

Named Parameters for PreparedStatement - Java World

  • 這篇文章提供了 NamedPreparedStatement 的實作。這麼一來，SQL指令就可以有更高的可讀性，而且不會被一大堆的 '?' 和 index 給搞混了！Cool~~~

Ajaxian » Transparent Messages in JavaScript

  • 這裡介紹了如何使用「半透明訊息區塊」來取代生硬的 alter 警告對話框。基本上，這牽涉到一些比較「人性化」的介面設計。試試看他的範例吧，很不錯喔！ - benxshen on 2006-09-25
