jsp - jstl <c:foreach error "attribute items does not accept any expressions" -


नीचे mentiond मेरा jsp पृष्ठ jstl sql क्वेरी है: 

  & Lt; sql: क्वेरी sql = "postname चुनें, root.posts से टिप्पणियां" var = "rs" डेटा स्रोत = "$ {ds}" / & gt; & Lt; c: forEach var = "पंक्ति" आइटम = "$ {rs.rows}" & gt; & LT; टीआर & gt; & Lt; td align = "center" & gt; & lt; c: out value = "$ {row.postname}" & gt; & lt; / c: आउट & gt; & lt; / td & gt; & Lt; td align = "center" & gt; & lt; c: out value = "$ {row.comments}" & gt; & lt; / c: आउट & gt; & lt; / td & gt; & Lt; / टीआर & gt; & Lt; / c: foreach & gt; Jsp मेरी त्रुटि निष्पादित करने के बाद:  विशेषता आइटम कोई अभिव्यक्ति नहीं स्वीकार करता है  और त्रुटि कॉर्डिएट शो (28,3) जो कि -  & lt पर है ; C: foreach var = "पंक्ति" आइटम = "$ {rs.rows}" ..  
 
 मेरा  context.xml  फ़ाइल है:

 मेरा  web.xml  फ़ाइल:

 अतिरिक्त जानकारी: 
 -  एलेप्से इंडिगो  
 - सर्विसलेट संस्करण 3 के अंदर डेटाबेस के लिए  एंबेड डर्बी  का उपयोग करना 
 - jstl.jar संस्करण 1.2, मानक.जर संस्करण 1.1.2 
 -  एचटीएमएल 5  
 का प्रयोग करके: ट्यूटोरियल से लिया गया है: (वास्तव में ट्यूटोरियल सर्वर संस्करण का उपयोग कर रहा है डर्बी ने इसे संशोधित करने के लिए एंबेडेड डर्बी में इसे संशोधित किया है) 
 - सफलतापूर्वक जेएसटीपी, सर्वलेट, जेएसटीएल के साथ MySql डीबी का उपयोग करके क्रूड एप्लीकेशन तैयार किया है, लेकिन  एंबेड डर्बी  के साथ नहीं (क्योंकि एम्बेडेड डर्बी भी उपयोगी है मेरे स्टैंडअलोन एप्लिकेशन और वेब एप्लिकेशन)

आप जेएसटीएल 1.0 के यूआरआई का प्रयोग कर रहे हैं, जो इसे संभाल नहीं करता अभिव्यक्ति की भाषा।

अपना जेएसटीएल यूआरआइ को सही करें: 

  & lt;% @ taglib prefix = "c" uri = "http://java.sun.com/jsp / JSTL / मूल "% & gt;

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

multithreading - Reorderings in java memory model -

Read again, find out I do not understand a sentence: We consider only the variables here that are readable and writeable as a nuclear unit - That is, there is no bit field, unrecognized access , or larger than the word sizes available on any platform. is. Anyone can explain the above cases on which the words are bold. On some architectures, the processor can access multiple storage in one command: BIT FIELD: Setting up some pieces of memory; It is usually implemented with different access to reading and writing, using read-write-write. Unwritten Access: On some CPU architectures, the processor impedes the barriers to the addresses you can use, when you access multibeat values, especially if you exceed the word limitations. Most modern processors Does not have this problem because they can perform multiple readsets to cover the required address range; If you read from 0x01 to 0x05, then it is read 0x01-0x04 and a 0x05. If you have to write there, then it is complicated;...

java - Add color code support to a Bukkit plugin -

I would like to add color code support in my config.yml . How do I add translateAlternateColorCode to my code correctly? Public boolean on command (CommandSender sender, command CMD, string label, string [] args) {player player = (player) sender; If (cmd.getName () .all ignored cas ("member") {player.sendMessage (getConfig (). GetString ("member text")); } You can simply use translateAltranateColorCodes . Here's an example: string nonColoredText = getConfig (). GetString ("member text"); // "member text" string get colored text = raw string. Translate Altinetic Color Code ('& amp;', nonColoredText); // Edit the colors code Any of the above text which is & amp; starts with the correct color code, for example, if & amp; A was in config, it would convert it to green color or ChatColor.GREEN , which will show the message in green, it also works with other characters such as you color If you want to use...
