윙크(http://www.debugmode.com/wink/ )를 이용하면 좋을 것 같다.

Introducing Wink...
Wink is a Tutorial and Presentation creation software, primarily aimed at creating tutorials on how to use software (like a tutor for MS-Word/Excel etc). Using Wink you can capture screenshots, add explanations boxes, buttons, titles etc and generate a highly effective tutorial for your users.
Here is a sample Flash tutorial created by Wink. Click the green arrow button to start viewing it. -------->
(More tutorials created by Wink users and companies can be found at the User Forums.)

This is a good example of how you can create tutorials in Wink, by capturing screenshots, mouse movements and specifying your own explanations with them. And all this in a standard Windows-based UI with drag-and-drop editing makes it very easy to create high quality tutorials/documentation.

It is estimated that Macromedia Flash Player is installed in more than 90% of the PCs. Using Wink you can create content viewable across the web in all these users' desktops. Similar applications sell for hundreds of dollars, while Wink is free with unrivaled features. So spread the word about Wink to your friends.

Sample: Click the green button to play

configuration : Tomcat 5.5. Apache 2.0


얼마전 톰캣 로그에서 다음과 같은 Exception이 발생했고, L7 체크(jsp 체크)에서 걸려서 L4에서 약 1분동안 빠지는 일이 발생했다.
Recently, a awkward exception of tomcat is occured below, and failed in L7 check (jsp check), the tomcat server were removed L4 equiment.

나는 확인해서, 찾아봤더니 이는 톰캣의 mod_jk 연동부분이었다.
I checked up, I found that exception happened in mod_jk of Tomcat.

If host part of Http header contains semicolon(;),  Below Exception is occured. 

재현 시나리오는 다음과 같다. 당신은 확인이 가능할 것이다.
I tried to do reviva scenario like below.  You may find on your tomcat.

Reference
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23)

14.23 Host

The Host request-header field specifies the Internet host and port number of the resource being requested, as obtained from the original URI given by the user or referring resource (generally an HTTP URL,

as described in section 3.2.2). The Host field value MUST represent the naming authority of the origin server or gateway given by the original URL. This allows the origin server or gateway to differentiate between internally-ambiguous URLs, such as the root "/" URL of a server for multiple host names on a single IP address.

       Host = "Host" ":" host [ ":" port ] ; Section 3.2.2

A "host" without any trailing port information implies the default port for the service requested (e.g., "80" for an HTTP URL). For example, a request on the origin server for <http://www.w3.org/pub/WWW/> would properly include:

       GET /pub/WWW/ HTTP/1.1

       Host: www.w3.org

A client MUST include a Host header field in all HTTP/1.1 request messages . If the requested URI does not include an Internet host name for the service being requested, then the Host header field MUST be given with an empty value. An HTTP/1.1 proxy MUST ensure that any request message it forwards does contain an appropriate Host header field that identifies the service being requested by the proxy. All Internet-based HTTP/1.1 servers MUST respond with a 400 (Bad Request) status code to any HTTP/1.1 request message which lacks a Host header field




원인은 잘못된 리퀘스트 (host 정보에 스펙에 맞지 않은 내용이 올 때 문제)로 인한 것이다...

아래와 같이 textarea를 사용하면, html 태그를 내부적으로 사용할 수 있다.
아래코드의 문제는 width, height쪽이 통제가 되지 않는데. 딱 fix해서 쓰려면 java script를 써야 한다.

Tag Libarray - Fn:replace

web 2009. 11. 26. 11:56

If you want to change a string some file, you can use fn:replace tag libs.

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
..

<pre>
${fn:replace(content.value.summary,'<', '&lt;')} 
</pre>
..


In my case, I have to change '<' character to '&lt', because some tag.(ex. table) have priority over per..
So, I have to use it.

ProtocolCodecFactory를 이용해서 스트림을 보내야 한다.

다음 주소 참조.

아파치 Mina 1.0에서 2.0 을 올리니. Connector 쪽에 약간 변경이 생겼다.

다음 URL 보면 쉽게 이해가게 고칠 수 있다.


http://www.nabble.com/-CONF--Apache-MINA-%3E-Sample-TCP-Client-td25396761.html




  private static final SocketHandler HANDLER = new SocketHandler();
  future = socketConnector.connect(address, HANDLER, config);

=>
    socketConnector.setHandler(HANDLER);
    future = socketConnector.connect(address);
    future.awaitUninterruptibly();


(옛날 코드는 그냥 그대로 두지..ㅡ.ㅡ;;)
