Directory listing server side

Hi,
I am looking to provide a list of files. These files exist on the application server (it is actually the image directory i wish to list). I have had a look at the package text_io which can read and write files to the server side, but there doesnt seem to be a way to list files.
Does anyone here know a way of doing this. I cannot do it via the database as the database and App server will exist on different boxes

As you have probably found out there is no native functionality to do this within PL/SQL Another alternative to those already suggested is to use JAVA
Tom Kyte has an excellent example here:

  • Cascading lists drop downs in SharePoint Designer (no server-side code) without postback

    I've created cascading drop downs populated from SharePoint lists, by following
    this post by Lars in SharePoint designer without using code, it works fine, my issue is that the secondary drop down only populates if the main drop down causes auto-post-back, is there any way to make the secondary drop down populate without causing
    post back and without using server-side code?
     

    Since you are using the ASP:DropDownList, you will need the post-back since it's a server-side control that doesn't use a callback. The following JavaScript library provides for a way to creating cascading dropdowns on the client-side,

    Download the free TextWrangler and drag the enclosing folder into it. Alternatively, open the AppleScript Editor in the /Applications/Utilities/ folder, paste the following in:
    do shell script "ls -AR " & quoted form of POSIX path of ((choose folder) as alias) & " >> ~/Desktop/inventory.txt"

  • Prepopulating dropdown list on server side

    We are preparing a PoC for a potential customer and they want to see how to prepopulate a dropdown list on server side. We found some useful samples from internet. But all of them are using roughly same method: get data from database and populate into a hidden text box then populate into dropdown list by javascript.  But when I compare this solution with other LiveCycle utilies I believe that there must be another simple method. (Maybe came with ES2 so there is no documentation on internet yet. )  So we decided to consult you? Do you have any suggestions?
    Thank in advance.
    Here are sample links for the common solution on internet:

  • Pb Server-Sides inludes  + Dynamic List Wizard with PHP 5.2

    Hi
    I include some Dynamic Lists in a master page with Server Side Include beahavior.
    It was Ok in PHP 5.1 with any number of items (50 items per page).
    But there is problem with PHP 5.2, it's OK with 20 items per page, nothing is displayed with 50 items per pages.
    I've seen that there is a new memory manager for the Zend Engine with PHP 5.2...
    SO I modified some parameters in php.ini (memory_limit...) with no result.
    Is there somebody have the same problem, an idea ?
    Thank you
    Marie

    Hi Marie,
    I´m running PHP 5.2.2 with the Zend Memory Manager enabled as well, and so far I didn´t encounter such issues -- maybe you´ll just need to increase the currently defined "max_execution_time" value ?

  • Directory Listing Using Weblogic Server

    Hi all,
    I need to be able to browse few directories via web page using Weblogic as WebServer ( on Linux RedHat 5.0)
    for example the directory to be browsed are:
    /home/oracle/swift
    /home/oracle/payables
    Please let me know how I can achieve this !!
    Thanks
    KS

    maybe it's a bit overkill to use the JCA File Adapter
    http://docs.oracle.com/cd/E21764_01/integration.1111/e10231/adptr_file.htm#BABFGIEJ
    which has a "directory listing" feature
    but I think it's not very recommended to use directly the java.io.File class to perform this operation...
    any other thoughts?

  • Still!!! server side activities have been updated. restart SPD to use the updated version of activities

    server side activities updated... restart SPD to use latest activities"
    pretty huh? I have been working with SP13 online and a custom list which I would simply like to add a workflow too,
    When creating a workflow I receive this error, I have uninstalled SPD I have cleared/deleted cache files in the following locations:
    <user profile>\appdata\roaming\microsoft\SharePoint Designer\ProxyAssemblyCache
    < user profile>\appdata\local\microsoft\websitecache\<sitename>
    restarted computer
    reinstalled SPD
    and...same message "server side activities updated... restart SPD to use latest activities"
    Same Image as above
    Now what else can I do, there aren't any language packages other than the default English, and a lot of people find this issue with no luck as to a resolution, need an answer that will work

    In my case the solution to this problem was the following. I discovered that the contents of <user profile>\AppData\Local\Microsoft\WebsiteCache\<sitename>\<version> was empty aside from Activity.xml for the website in question. This directory
    should actually download the following list of files from the server in order for the workflows to operate in SPD. This is not the case when things go wonky.
    Microsoft.ReportingServices.SharePoint.UI.WebParts.Proxy.dll
    Microsoft.SharePoint.WorkflowServices.Activities.Proxy.dll
    Microsoft.Web.Design.Client.dll
    Newtonsoft.Json.dll
    ProxyAssembly.xml
    System.Net.Http.dll
    System.Net.Http.Formatting.dll
    System.Net.Http.Formatting.xml
    System.Net.Http.xml
    System.Web.Entity.Proxy.dll
    System.Web.Extensions.Proxy.dll
    So I found that if I copied these from another websitecache directory that is working or perhaps copying them from another machine where SPD is working properly that my workflows will start working once again. I haven't checked but I'm certain that you could
    hunt down all these dll's manually on the server as well.

  • Directory listing : Codepage problem ???

    Hi there,
    i want to fetch a list of files from a specific directory (the directory would be in the application server and not in the presentation server) during a background execution of a report.
    I have tried the function modules 'SUBST_GET_FILE_LIST' and 'EPS_GET_DIRECTORY_LISTING'.
    The problem is that the list of files comes with unknown characters when there is a file name with Greek characters.
    Is this an application server setup problem or there is a possibility to get a correct file list through another function module?
    Thanks in advance.

  • HOWTO: Setting up Server-Side Authentication with SSL

    This howto covers the configuration of server-side SSL authentication for both Net8 and IIOP (JServer) connections. It documents the steps required to set up an SSL encrypted connection; it does not cover certificate authentication.
    It is worthwhile noting that although the setup of SSL requires the installation of certificates, these certificates do not have to be current, only valid. For some reason, in order to enable SSL connections, it is necessary to set up valid certificate file on the server whether you intend to use certificate authentication or not.
    NOTE: I have been unable to determine whether or not the above statement is entirely correct. If anyone can confirm or disprove it, please let me know.
    The steps described below must all be carried out from the same logon account. They have been tested on both 816 and 817 databases, but will probably work for all versions, including 9i (unless there have been some drastic changes in 9i that I'm not aware of).
    1. Log on to the database server with an administrative login.
    Configure the database and listener to run under the current login account (Control Panel -> Services). It is not necessary to restart these services at this time.
    2. Create an Oracle wallet and set up the required certificates
    (i) Open the Oracle Wallet Manager:
    Start -> Programs -> [Oracle Home] -> Network Administration -> Wallet Manager
    (ii) Create a new wallet (Wallet -> New).
    (iii) When prompted, elect to generate a certificate request.
    (iv) On the request form, the only field that matters is the Common Name. Enter the fully qualified domain name (FQDN) of the database server (i.e. the name with which the database server will be referenced by clients).
    (v) Export the certificate request to file (Operations -> Export Certificate Request).
    (vi) Obtain a valid server certificate from an authorised signing authority. It will also be necessary to download the signing authoritys publicly available trusted root certificate. Certificates can be obtained from Verisign (http://www.verisign.com/)
    (vii) Install the trusted root certificate obtained in (vi) into the wallet (Operations -> Import Trusted Certificate). Either paste the contents of the certificate file, or browse to the file on the file system.
    (viii) Install the server certificate obtained in (vi) into the wallet (Operations -> Import User Certificate). Either paste the contents of the certificate file, or browse to the file on the file system.
    (ix) Save the wallet (Wallet -> Save). The wallet will be saved to the [user home]\Oracle\Wallets directory.
    3. Configure the listener for SSL.
    (i) Open the Oracle Net8 Assistant:
    Start -> Programs -> [Oracle Home] -> Network Administration -> Net8 Assistant
    (ii) Select Net8 Configuration -> Local -> Profile.
    (iii) From the drop-down list at right, select Oracle Advanced Security. Select the SSL tab.
    (iv) Select the Server radio button.
    (v) In the wallet directory field, enter the location of the wallet created in step 2, e.g. C:\WINNT\Profiles\oracleuser\ORACLE\WALLET
    (vi) Uncheck the Require Client Authentication checkbox.
    (vii) Select Net8 Configuration -> Listeners -> [listener name].
    (viii) Add a new address:
    Protocol: TCP/IP with SSL
    Host: [database server FQDN] (e.g. oraserver)
    Port: 2484
    (ix) Add a second new address:
    Protocol: TCP/IP with SSL
    Host: [database server FQDN] (e.g. oraserver)
    Port: 2482
    Check the Dedicate this endpoint to IIOP connections checkbox.
    (x) Save the Net8 configuration (File p Save Network Configuration).
    (xi) Restart the listener service.
    4. Configure the database to accept SSL connections.
    (i) Open the database inti.ora file (\admin\[SID]\pfile\init.ora or equivalent).
    (ii) At the bottom of the file, uncomment the line that reads
    mts_dispatchers = "(PROTOCOL=TCPS)(PRE=oracle.aurora.server.SGiopServer)"
    (iii) Save the file and restart the database service.
    5. Test the SSL confi guration using the Net8 Assistant.
    (i) Open the Oracle Net8 Assistant.
    (ii) Select Net8 Configuration -> Local -> Service Naming.
    (iii) Add a new net service (Edit p Create).
    Net service name: [SID].auth (e.g. iasdb.auth)
    Protocol: TCP/IP with SSL
    Host: [database server] (e.g. oraserver)
    Port: 2484
    Service Name/SID: [SID] (e.g. iasdb.orion.internal)
    Note: at the end of the net service configuration, click Finish, not Test. The test can hang if run from the wizard.
    (iv) Test the connection (Command -> Test Service). If the only error to appear is username/password denied, the test has succeeded.

    Dear Alex,
    Thank you for reaching the Small Business Support Community.
    I would first suggest you to uncheck the "Perfect Forward Secrecy" setting on the RVS4000 and if see if there is some similar setting enabled, then disable it, on the other side.  If still the same thing happens, then go to RVS4000, VPN Advanced settings, and disable the "Aggressive Mode" so it becomes "Main mode" and use the same on the other end of the tunnel.
    Just in case and as a VPN configuration guide, below is a document called "IPSec VPN setup" if it helps somehow;
    http://sbkb.cisco.com/CiscoSB/Loginr.aspx?login=1&pid=2&app=search&vw=1&articleid=587
    Besides my suggestions I would advise you to contact your ISP to make sure there is no IPSec traffic restrictions and/or if there is something in particular they require to make this happen and please do not hesitate to reach me back if there is any further assistance I may help you with.
    Kind regards,

  • Poriblems with Server Side Include

    I amtrying to convert to Spry Menus using SSI. into a template.  been beating my head against the wall on what can go in and what can't in an include fil but that turns out not be my big problem
    when in using Dredamweaver CS5   and  do a server side I have major issues at the differeent levels
    i have the file in a directory off the site root called  Includes
    the file i am trying to include
    using a page at the root level my statement using document relation is
    <!--#include file="Includes/Navbar.html" -->
    works fine   channg to site relation does not work   Ok so far so good
    however a page in a lower level director gets the dreaded
    [an error occurred while processing this directive]
    and i get an error
    [Sat Sep 01 16:51:42 2012] [error] [client 174.57.220.98] unable to include file "../Includes/Navbar.html" in parsed file /usr/local/www/kasdivi.com/blog/beachguide.html

    the php errors don't seem mahor although they seem to have i have another iisue or are the related
    but that aside
    If I move the include file to the same level as the pade with approprirate include statement no problem it works
    if i move it to a subditrectory  then it doesn't work
    summary
    i can get SSI to work for page on the root level using Includes from a subdirectory
    but on other level I must have the include in the same directory with the page
    any thoughts??

    Your menu links are inside an include file.  There should be nothing else inside that file except the list tags, classes & hyperlinks.  Links are relative to the parent page(s) in which they will occur.
    All supporting scripts and CSS go inside the parent page -- in your case, the Template.dwt file.
    Local Files Panel:
         -Includes
              menu.html
              footer.html
         +Styles
         +SpryAssets
         -Templates
              main.dwt
         about.shtml
         contact.shtml
         index.shtml
         services.shtml
    Problems will occur if you use document relative link paths with pages that are located inside sub and sub-sub folders. Obviously, you want to avoid doing that.  For best results, keep all your site pages at root level.
    Hope this helps,
    Nancy O.

  • Server side script not running on stand-alone XE

    Hello,
    In my application I created a Server side script (AJAX) which presents a select-list based on other fields on the page. The very same application runs on a 10g+APEX3.0.1 database AND on a standard XE+APEX2.1 database, which are both accessed via a HTTP-server. The application with the script runs fine on this platform (XP).
    I have two other XP-machines on which I also installed XE+APEX2.1. Both are stand-alone versions NOT accessed via a HTTP-server. I installed exactly the same application which runs on the platform with HTTP server on both of the machines. While testing the correct functioning, I noticed that everything works ok, EXCEPT the server side script which gives me a better select list. Instead of this I get the old-fashioned version of the select-list which is not able to use the value elsewhere on the page.
    I found a similar problem on the XE forum (Re: Server side scripts features ) but it doesn't answer my question how to get the script working on a standalone version of XE (= without access via a HTTP-server).
    Can anybody please help me?
    Thanks & regards,
    Jan.

    Carl,
    Thanks for your suggestion to install FireFox and the Firebug tool (which I wasn't aware of).
    After having looked at the problem for hours, I found what I think is the problem: the htmldb_html_elements.js script.
    As already mentioned, the properly functioning XE on my local PC is accessed via a HTTP-server, as well as the 10gR2+APEX3.0.1 version also running on that PC.
    On the laptop, not running HTTP-server, I get the message: <br>
    <FONT COLOR="RED">$x is not defined <BR>
    <FONT COLOR="BLUE"> f_21_select_kpn<FONT COLOR="RED">(<FONT COLOR="BLUE">input<FONT COLOR="BLACK">#P21_GBREKNR 405<FONT COLOR="RED">, "P21_KOSTENPOST") <BR>
    <FONT COLOR="BLUE">onblur<FONT COLOR="RED">(<FONT COLOR="BLACK">blur <FONT COLOR="RED">)
    </FONT><BR>
    That is in the 'Console' of Firebug.
    When changing to Script I do see a remarkable difference.
    On the PC there the following text is found in the first lines of htmldb_html_elements.js:
    /*htmld_elements will contain the lower level html access js*/<br>
    var gDebug = true;<br>
    var gkeyPressTime;<br>
    var gLastTab=false;<br>
    var gRegex=false;<br>
    var ie=(document.all)?true:false;<br>
    if(ie){document.expando=true;}<br>
    var gDebugWindow = false;<br>
    /*<br>
    $x functions have to do with either single elements or array of elements<br>
    $v functions have to have to do with manipulating values or interaction based off a value<br>
    $xml function have to do with manipulating xml values<br>
    $a functions are based on ajax<br>
    $d functions are specific dhtml constructs<br>
    */<br>
    /* begin $x functions */<br>
    function $x(pNd){<br>
    try{<br>
    var node;<br>
    ...<br><br>
    On the laptop however the first few lines are:<br><br>
    /*htmld_elements will contain the lower level html access js*/<br>
    <br>
    var gDebug = true;<br>
    var gkeyPressTime;<br>
    var gLastTab=false;<br>
    var gRegex=false;<br>
    if(document.all){document.expando = true;}<br>
    // Elements //<br>
    <br>
    function html_GetElement(pNd){<br>
    try{<br>
    var node;<br>
    switch(typeof (pNd)){<br>
    ...<br><br>
    I think that the difference is in these two scripts.
    But why are the scripts different: it is the same XE that is installed on the laptop and the PC.<br>The answer I found in the images/javascript directory of APEX3.0.1 which is located in the APACHE directory-tree (you have to copy the images to APACHE when you use the HTTP-server). And indeed: the htmldb_html_elements.js has exactly the same text as what I see in Firebug on the PC. So XE on the PC is using the javascripts in the image-directory of APACHE on the PC and not the XE-version of the scripts, embedded in XE.
    <br><br>
    So the answer seems to be: copy the APEX3.0.1 versions of the script over to the PC and try to get them into the database. Or...???
    <br>
    Can it be loaded into the database? Will XE accept it?
    <BR><br>
    Would be nice to have answers if the conclusion I found is the right one and if it can be fixed by loading the js into XE.
    <br>
    Best regards and thanks for your help so far.
    <br>
