The following files/directories in the META-INF directory are recognized and interpreted by the Java 2 Platform to configure applications, extensions, class loaders
and services:

  • MANIFEST.MF

.................

Tag libraries should be packed with their .tlds packed in their META-INF directory. JSP engines look through the JAR files in the /lib directory for TLDs and add the tags as necessary. Then when you are installing tag libraries, you only need to deliver one file - the JAR - no changes to the web.xml, no extra tlds hanging around.

]]>Why the select method of JTextArea don't take effect.http://www.blogjava.net/xmoses/archive/2006/02/20/31629.htmlJava-XMosesJava-XMosesMon, 20 Feb 2006 05:32:00 GMThttp://www.blogjava.net/xmoses/archive/2006/02/20/31629.htmlhttp://www.blogjava.net/xmoses/comments/31629.htmlhttp://www.blogjava.net/xmoses/archive/2006/02/20/31629.html#Feedback1http://www.blogjava.net/xmoses/comments/commentRss/31629.htmlhttp://www.blogjava.net/xmoses/services/trackbacks/31629.htmlIn my swing UI, there is JTextArea component named "textarea_webpage", I want to mark some sentence in the textarea as marked using program just as user selecting them using mouse.
------------------------------------------------------------Code Below-------------------------------------------------
textarea_webpage.setSelectionColor(Color.black);
textarea_webpage.setSelectedTextColor(Color.white);
textarea_webpage.setSelectedTextColor(Color.white);
textarea_webpage.select(urlItem.getStart(),urlItem.getEnd()); // the urlItem is self-defined object to store positon information of certain sentences
----------------------------------------------------------------------------------------------------------------------------

Every time the code is executed, there is nothing take place in my textarea.
After goolge for the answer in the net.
I found that I forgot the code 
         textarea_webpage.getCaret().setSelectionVisible(true);

There are so many tricks in Swing designing, I'm just a beginner.
Pay more attention.
