Cannot find the tag library descriptor

I trying to do the Java EE 5 Tutorial. It is called 'hello1' (chapter 2) and it's supposed to run a 'hello duke' program. However it is in Netbeans and I am trying to use ECLIPSE.
I've tried to paste it into Eclipse but I get the following error message:
Cannot find the tag library descriptor for http://java.sun.com/jsp/jstl/core
when trying to include the following taglib:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
Any ideas? I'm sure it's a very basic fix but I am new to Eclipse and web development.
thanks in advance.

Check whether sharing reference and other details in portalapp.xml are correct.

JSPDynPage : Cannot find the tag library descriptor for tagLib

Hi,
I'm working JSPDynPage and i have error in IDE at design time.
i just created one JSPDynPage component. and an error is shown at the uri="tagLib"
<%@ taglib uri="tagLib" prefix="hbj" %>
The problem is that the word 'tagLib' is marked and has the hoovering text "Cannot find the tag library descriptor for tagLib". Why is this? Do I have to do add some dc dependency ? Or is there another cause for this problem?
I am working with CE 7.2 .
portalapp.xml
<?xml version="1.0" encoding="utf-8"?>
<application>
<application-config>
    <property name="SharingReference" value="com.sap.portal.htmlb"/>
</application-config>
<components>
    <component name="GCPPURLJSP">
      <component-config>
        <property name="ClassName" value="com.cts.gc.GCPPURLJSP"/>

Hi Pavan,
For using htmlb, you can use another tag library. Use the below code in your jsp
<%@ taglib uri = "prt:taglib:tlhtmlb" prefix="hbj" %>
And in portalapp.xml, replace the <property> of <component-profile> with the below line.
<property name="tlhtmlb" value="/SERVICE/com.sap.portal.htmlb/taglib/htmlb.tld">
Also, you may need to add the import statement for htmlb, if not done earlier -
<%@ page import = "com.sapportals.htmlb.*" %>

The tag handler gridcolumn does not have a setter for the attribute autoExpand specified in the Tag Library Descriptor.

So, how to correct this behaviror ? is there a patch?

I want to copy my iPhoto library to an external drive but I cannot find the folder on my Mac Air. When I open Finder there is no Picture folder showing so I cannot find the iPhoto library.

I want to copy my iPhoto library to an external drive but I cannot find the folder on my Mac Air. When I open Finder there is no Picture folder showing so I cannot find the iPhoto library.

Choose Go to Folder from the Finder's Go menu and provide ~/Pictures/ as the path. If that doesn't work, control-click a photo in iPhoto, show it in the Finder, and Command-click the folder's name in the window's title bar to find the path.

I have two IPad's and tried to create two Itune libraries on my computer. Now I cannot find the original library on my computer and the Ipad will not sync?

I have two Ipad's and tried to create two ITune Libraries on my computer. Now cannot find the original library on my computer and the Ipad will not syc?

You should be able to accept this message, it will cause existing music, photos (not camera roll) and videos (also excluding those in camera roll) to be removed and replaced with those from this computer. All other user data on the iPad will be unaffected.

My iPhoto would open with stating the files were damaged. I created a new library, thinking I could just retrieve the old one through the Pictures folder. Now I cannot find the old library.

I fear I may have deleted ALL my photos!!! When opening iPhoto it stated that the photos were damaged. By creating a new photo library, I now cannot find the old photos in the Pictures file. I think I really screwed up!!!

Download and run Find Any File to search for "Library6.iPhoto" on your hard drive. That's a file that is in every iPhoto library. And Find Any File can search inside packages as areas that Spotlight can not.
See if you find more than one of those files. If you do then you can find out where that other library is. If there's only one found click on the Desktop to get to the Finder and use the Go ➙ Go to folder... menu option. Enter in the window /Volumes.
When you created the new library did you get this window where you were to either accept the default name that iPhoto presented or rename the new library?

Cannot find the shared library on linux

Hello everyone!
I'm running labviee 2010 on ubuntu 10.10 64bit. Everything works fine except calling shared object files.
As long as I use gcc without any optimization, there is no problem at all, but if I switch on optimization in gcc labview claims being unable to find the shared object file, though I can find an select it in the corresponding dialog window.
Whenever I use the actual intel compiler (composer xe 2011) with, or without optimization, the same problem occurs. As expected ldd doens't show any other dependencies for the optimized and unoptimized case.
can anybody help me please??

Perhaps this KB Entry might be helpfull.

Eclipse vs. (WebCenter) Portlet Tag Library Descriptor

Hi there,
one more question: What's the best way to teach Eclipse WTP about the portlet tag library (http://java.sun.com/portlet_2_0) mandated by JSR 286 and bundled with WebCenter itself? So far, it complains that it 'Can not find the tag library descriptor for "http://java.sun.com/portlet_2_0"')....
For example, where can I find the actual physical TLD file that describes the WebCenter-specific implementation of this library? Or should I use the equivalent TLD coming from another portlet container (e.g. Apache Pluto), instead (while working within Eclipse, at least)?
Thanks in advance,
Chris

I'm not sure that this IDE warning really matters. Things should work fine, when you deploy your portlets into the portal container. But have you tired:
Oracle/Middleware/jdeveloper/webcenter/modules/oracle.portlet.server_11.1.1/oracle-portlet-tags.jar
You'll find a portlet TLD within that jar.

I was told by the Apple store to create multiple user ids to control the content on my iphone. I did that and now I cannot find my original library with all of my playlists

I was told by the Apple store to create separate user ids on my windows computer to create a new library to control the content on my iphone. I held down shift and clicked i tunes and created the library. I was told you can switch back and forth. I cannot find the old library and all of my playlists. Apple really needs a better way for families to manage their libraries and devices. This is such a pain in the butt!

No, as I stated in the post this is the first issue we've had with the phone. No, this was not a replacement phone, this is the same phone I bought from the apple store in December and had not been serviced by anyone, it did not have any issues until last week.

Tag Library Descriptor

I am trying to use the dbtags from Jakarta using Tomcat and MySQL. When I try to call my ASP I keeping getting an error that says:

The iPhoto library should be in your user folder/Pictures unless it was moved.

I just downloaded itunes to my PC but cannot find the library page to start transporting music files

I just downloaded itunes to my PC but cannot find the library page to start transporting music files ?????

I have music on a stick drive which I want to transport to itunes on my desktop PC running Vista. I downloaded itunes but cannot find a page on itunes to load the music onto.. When I put the stick into the USB port, an AutoPlay box comes up which says Play using .Windows Media Player..............Import music, pictures, video using Real Player. Open folder to view files using Windows explorer etc.....& set Auto Play Defaults in control Panel. By library page, I mean the page on itunes where the music would be transported to & listed by each name so I can listen to it.
