Cannot find the tag library descriptor Error

Hi
In SAP Netweaver Developer Studio 7.3 SP 03, i am facing the following problems:
- When compiling JSP portal applications i am having problems using SAP tag library's or classes. Do i need to configure the class path for a specific path in the server?
Error: Can not find the tag library descriptor for "LayoutTagLibrary"
Portalapp.xml
<property name="LayoutTagLibrary" value="/SERVICE/com.sap.portal.pagebuilder/taglib/layout.tld"/>
JSP
<%@ taglib uri="LayoutTagLibrary" prefix="lyt" %>
Regards
Eben Joyson

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 .

    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.*" %>

  • 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.

    I have researched quite a bit about this and haven't anything solid. Most of the discussions suggest to clear the .fsd file and let the whole app layer re installed. 
    I am hesitant to do that as this is happening for only one user and for particular app.

    you can try to 'repair' the application: Ask the user to close all applications of that package, then use the App-V client MMC (sftcmc.msc) to locate the application entry. Right-click and 'repair'. This has to be done in the user's context/session

    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.

  • [Forum FAQ] Cannot perform a backup schedule via Windows Server Backup and receive "The system cannot find the path specified." Error

    Symptom One
    You attempt to
    schedule a backup every day via Windows Server Backup on Windows Server 2008 R2. At the beginning, the backup works without issue. But after a few days it failed and you receive the error “Windows Server Backup:
    The system cannot find the path specified.”
    Cause
    The issue may occur if there is
    no shadow copy storage space available on the backup volume.
    Verify
    You can use the List ShadowStorage command to check if you have enough storage space to store the newly created shadow copy. If you've reviewed the size of the backup snapshot and discovered
    that there is no allocated space for the storage association, you need to resize shadowstorage.
    Solution
    You could run the command below to create shadow copy storage space on the backup volume:
    vssadmin resize
    shadowstorage /for=<ForVolumeSpec> /on=<OnVolumeSpec> [/maxsize=<MaxSizeSpec>]
    More Information
    Vssadmin resize shadowstorage
    http://technet.microsoft.com/en-us/library/cc788050.aspx
    Symptom Two
    When you add
    another external hard drive to backup schedule via Windows Server Backup on Windows Server 2012, it fails and you receive the error “The System cannot find the path specified.”
    Cause
    The issue is due to the
    Original Destination Disk was not attached to the server.
    Verify
    You could check the disk status in Disk Management to see if the Original Destination Disk is offline or removed.
    Solution
    You need to attach
    Original Destination Disk to the Server then choose another external hard drive as backup target. After that, you could remove the Original Destination Disk.
    Workaround
    To work around this issue, please use the WBADMIN command line tool to add disk.
    WBADMIN ENABLE BACKUP -addtarget :{ DiskID}
    The AddTarget parameter takes disk ID as parameter. It can be retrieved by running "WBADMIN GET DISKS" command.
    Example:
    WBADMIN ENABLE BACKUP
    -addtarget :{ aa123d14-bba0-1dd9-0d93-80aaaa6bbb63}

  • 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?

    What version of the CAD software are you trying to install?  Is it compatible with win 7?  Older installations (on older OS) installed to a different default location that win 7 does not have.

  • 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??

  • LV Applicatio​n Builder: solving "The system cannot find the file specified.​" error?

    Hello everyone,
    I don't mind banging my head off of something that feels complex but it's always frustrating to be stumped by something that seems simple... I have LabVIEW 2014 and Application Builder. I've built an program that runs flawlessly as a VI, then compiles and runs flawlessly as a .exe. But I can't seem to get the installer to work. I get the following error:
     Per the suggestions in this thread and this KB article, I created a new installer build spec, then a new application build spec, then a new project with all my VIs in it, building and testing the installer at each step. None of that seemed to make a difference.
    I ran the installer as admin, I created the install directories ahead of time (in case it didn't have the privileges to create folders), and built an installer without the Run-Time in it. None of that worked either. Lastly, I played around with putting all my subVIs in a library.
    So since the tutorial worked I'm assuming that it's some quirk in my program. Does anyone have any experience or advice as to what specific aspects of a program play nice with the AB installers? It's one primary VI, less than a dozen subVIs, a few Type Defs, and no hardware integration. Seems like a pretty straightforward and simple program but maybe something in there is persona non grata with Application Builder?

  • 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.

  • Error code: 2147778144 Cannot find the QE property.

    I have been working to get Coldfusion 8 and Crystal Enterprise 10 to work together.  The following were two approaches I knew of to try:
    1) using Crystal "unmanaged URL reporting":
    a href="AOC_Summary.rpt?prompt0=#variables.Record_Month#&prompt1=#variables.Fiscal_Year#&user0=userid&password0=pswdn">AOC SUMMARY</a>
    2) using  the Coldfusion <cfreport> tag:
    <cfreport report = "AOC_Summary.rpt"  
    dataSource = "#variables.dsn#"  
    username = "userid" 
    password = "pswd">
    {AB145_AMTS.REC_MONTH} = 5 and
    {AB145_AMTS.FISCAL_YEAR} = 8
    </cfreport>
    I got the CFREPORT tag to work but was disappointed to find that it only rendered the report in HTML.  The reports we have been producing with our current configuration of CF4.5 & CR 8.5 can be saved as PDF's.  So I abandoned the Coldfusion <cfreport> tag to see if I could get the Crystal "unmanaged URL reporting" to work.  This included me trying to find any documentation anywhere to guide me along with going into Crystal Admin and 'experimenting' to see if there was anything I needed to do there to make the unmanaged URL reporting work.
    Management is now telling me that producing the report in HTML is acceptable.  I am now trying to set up a demo for management.  When I went back into my CF code and uncommented the work I had done with the CFREPORT tag (which had been working at the time I commented it out), I receive the following error code.
    CrystalReport Integration Exception.
    Error code: 2147778144 Cannot find the QE property.
    Error source: Crystal Reports ActiveX Designer 
    I have tried searching the SAP site to find more information on this error message to no avail.   Any guidance would be greatly appreciated.
