Dynamic Classpath Using ClassLoader

Once you use the ClassLoader to change the Thread.currentThread().getContextClassLoader() classpath, is there a way to reset it back be the ClassLoader.getSystemClassLoader() classpath?
I have a set of classes within an app that each need a separate classpath. Only the first one works correctly, the second to n classes in the set end up with an aggregate classpath that contains their specific information and the information of all classes before it.
Example:
Class foo is called first and gets the classpath: java default + foo paths
Class bar is called second and gets the classpath: java default + foo paths + bar paths
What I want to happen is for Class bar to get the classpath: java default + bar paths
Thanks in advance,
Brian

I am using separate classloaders. The problem is that the second classloader somehow inherits the newly created classpath of the first classloader. i thought maybe there was a common trick to doing this or to removing stuff from the classpath that someone was willing to share.

  • How to create a viewobject dynamically without using wizard

    Hi,
    I am Using jDEV 11G, i need to create a viewobject dynamically without using wizard, without binding from any entity.

    just like shopping cart.
    i have done thsi code:
    ViewObjectImpl view=new ViewObjectImpl();
    view.addDynamicAttributeWithType("Att1","String",null);
    view.addDynamicAttributeWithType("Att2","String",null);
    view.addDynamicAttributeWithType("Att2","String",null);
    Row rw=view.createRow();
    rw.setAttribute("Att1","First1");
    rw.setAttribute("Att2","First2");
    rw.setAttribute("Att2","First3");
    view.insertRow(rw);

  • Question regarding the creation of a custom dynamic stamp using "Will Print" from "Set Doc. Actions

    Hi all,
    Using Acrobat 9.0 Professional, I have successfully created a dynamic stamp using the forums where I have added Login / Date to my own image and it works great as designed.  However, the problem I am having is that when a document is stamped it becomes flat and doesn't update dynamically which does not work for my requirements.
    I need to create a pdf that is stamped by myself so that other users (using only Reader) can open the pdf and when printed the stamp will print with the correct date/time (in the format I describe below).
    I found a workaround (outside of a stamp) where I added a text box (called "Today") that updates everytime the document is printed by going to
    Advanced / Document Processing / Set Document Actions / Document Will Print
    and adding the following Java Code:
    var f = this.getField("Today");
    f.value = util.printd('yyyymmddhMMss', new Date());
    This provides me with the unique number that I need for printing  (ie: 20100317102030).  It works great as an inserted text field on my pdf.
    My problem is that when I use the "create custom stamp" as in other tutorials by inserting this new text field, it will not update (or display) on print, even though it was set the exact same way as the custom stamp I got working using the Adobe dynamic stamp information.
    Can you offer any advice on how I can get this to work as a custom stamp?  I would rather not have to create both a stamp and then overlay the text field manually as I have hundreds of documents (maybe more) to do this for.
    Also, as an aside, if I could get this to work, I would also like to add Login ID that updates in the same manner as my custom date format (but one problem at a time I guess! )
    Thanks for any and all help that you can provide.  I looked through these forums and elsewhere, but I don't seem to see anyone else with the same problems (with solutions posted).
    I really wish Adobe had a Custom Stamp creator as part of their program, with the dynamic option.  It would be so easy for them and save a lot of users so much time.

    Stamps are just like a inked rubber stamp, except in Acrobat you can suppress printing them and you can move them. So if you use a dated "Faxed" stamp when you fax a document, even though you can adjust the stamp before affixing the stamp, once the document is stamped the date on the document can not be changed or moved. It appears, that the use of a stamp might not be the best solution.
    "Interactive" means Acrobat JavaScript programing.
    With JavaScript not only can you insert variable data but also fixed text strings or a combination of both.
    So your script could be updated to something like:
    var f = this.getField("Today");
    f.value = "Printed : " + util.printd('yyyymmddhMMss', new Date());
    http://forums.adobe.com/message/1333261#1333261
    Getting the 'login name" will require some special JavaScript code being added to an application level JavaScript folder that runs upon initialization and is the data or function created is then accessed  by your PDF. This file will need to be installed on each user's system.

    With a PDF Dynamic form using show/hide actions, how to ensure that when the completed form is saved, closed and re-opened, the form still show the fields as before it was closed?
    I have developed a form with fields hidden by default, that become visible based on box ticked or radio button selections.
    My problem is that, when I close the form and re-open it, it comes back to it's default presentation, regardless of the information already recorded in the form (including in the now hidden fields.
    How to correct that

    Go to the "Form properties..." in the File-menu. Select "Run-time" to the left and in the box "Scripting" Preserve scripting changes to form when saved: choose Automatically (Script-based state changes are saved locally in an insecure fashion. This option cannot be used for certified forms).

  • How to create a dynamic newsflash using dreamweaver and PHP

    Hi there,
       I would like to create a dynamic newsflash using dreamweaver and PHP in that the newsflash will be pulling information from a MySQL database. The newsflash should also have a link to view more information about the piece of news a user wants to know more about. Which tools do I need to use in dreamweaver and how's the procedure to go about that. Any advice is highly appreciated. Thanx in advance!

    I think you´ll need at least a MySQL table with the following columns:
    - id (primary key, int, auto_increment etc)
    - news_headline (varchar)
    - news_teaser (text)
    - news_content (text)
    What I´d personally add are columns such as:
    - news_date (date or datetime)
    - news_external_link (varchar), if a "read more..." link is supposed to navigate to an external URL rather than displaying the contens of the "news_contents" column.
    Based on such a MySQL table it should be easy to use Dreamweavers standard Server Behaviors to create the usual datalist.php, insert.php, update.php and delete.php documents, and there are numerous tutorials out there which will teach you how to do that.
    Am I right when assuming that you´ll also need to know how to automatically pull, say, the 5 most recent news records from the database ?

  • How to create two level dynamic list using JSP , Java Script and Oracle

    I am new in JSP. And i am facing problem in creating two level dynamic list using JSP ,Java Script where the listdata will come from Oracle 10g express edition database. Is there any easy way in JSP that is available on in ASP.NET.
    Plz response with details.

    1) Learn JDBC API [http://java.sun.com/docs/books/tutorial/jdbc/index.html].
    2) Create DAO class which contains JDBC code and do all SQL queries and returns or takes ID's or DTO objects.
    3) Learn Servlet API [http://java.sun.com/javaee/5/docs/tutorial/doc/].
    4) Create Servlet class which calls the DAO class, gets the list of DTO's as result, puts it as a request attribute and forwards the request to a JSP page.
    5) Learn JSP and JSTL [http://java.sun.com/javaee/5/docs/tutorial/doc/]. Also learn HTML if you even don't know it.
    6) Create JSP page which uses the JSTL c:forEach tag to access the list of DTO's and iterate over it and prints a HTML list out.
    You don't need Javascript for this.

  • How to make dynamic actions using Set Value work in all browsers?

    I’m having a cross-browser incompatibility issue with dynamic actions using Set Value.  The dynamic action works like a charm on Chrome but has no effect on either IE or Firefox.  The code in oracle.apex.com and here are the credentials:
    Workspace: DDBA
    Username: [email protected]
    Password: redtruck12
    These code is on page 3 and here are the details:
    There are two report lists (Standard and Special) and some of the reports require additional information supplied in either select lists or text boxes.
    If the user selects a Standard report requiring a select list/text box, then the dynamic action sets the value of Special Reports to NULL (and vice-versa).
    The dynamic action is to prevent a simultaneous selection of both the Standard and Special reports.  To see how it works on Chrome, do this:
    Run Page 3
    Select the ‘Report for Search Criteria’ option from the Standard Report list.  A ‘Search Criteria’ text box appears
    Select the ‘Report by Release’ option from the Special Reports list.  A select list appears and the ‘Search Criteria’ text box disappears.
    If you do the same things on IE or Firefox, the text box does not disappear. 

    Hi,
    Things are going wrong with setting the item values to NULL. If you check your session state, you'll see that in chrome your items values indeed will be set to null, but in firefox they won't.
    Also I've noticed that you don't reset the other input fields, so their values persist in the session state. Since you submit your page every time you change one of the report select lists, this might lead to unexpected behaviour. Lastly, I've noticed you use a sql exists expression to manage the display/hide of your page items. A condition of type "Value of  expression 1 = expression 2" causes less overhead as you don't need to switch to the db sql engine for every item to validate.
    I'd suggest you rethink your specs and try to create:
    - One dynamic action (since a value of standard select excludes the value of special select, and vice versa)
    - Set the values for hidden items to null, also in session state
    - Use a refresh of region as extra event in your dynamic action, instead of submitting your page for every change.

  • Dynamic Routing Using Query String (SOAP)

    Does anyone have any examples on how to do a dynamic routing using a query string from a SOAP Adapter. I know how to get the query string but don't know how to map for dynamic routing.
    Thanks,

    After some further examination it seems that both calls are picked up by the same interface. In the RWB both the messages are picked up by the MIOS_GetDetails...

  • Dynamic ALV using REUSE_ALV_HIERSEQ_LIST_DISPLAY

    Hi All,
    My requirement is to display a dynamic output table using REUSE_ALV_HIERSEQ_LIST_DISPLAY.
    I was able to successfully display the dynamic output in grid display using REUSE_ALV_GRID_DISPLAY. But when I try to display the hierarchial list, then only the T_OUTTAB_HEADER data is getting displayed. The T_OUTTAB_ITEM is not getting displayed.
    I am creating the dynamic table using

    Any pointers in this regard will be helpful. Also any existing code for dynamic ALV for grid display, will be helpful.
    Thanks & Regards,
    Sonali.

    Hi All,
    Thanks for your inputs.
    All those demo programs are for displaying static output table. I need to display dynamic internal table.
    Also the table name LIST / <I_FS_DYNOUT> does not make a difference.
    Actually there is an existing tcode MB51. In this report first there is a list display, then when u click on detail button, then there is a grid display.
    I had to modify this report to add some more columns.
    So I made a copy and added few more columns to the output table dynamically.
    now when I pass data for list display to REUSE_ALV_HIERSEQ_LIST_DISPLAY, then my list display shows only header data. And when I click on u201Cdetailsu201Dbutton, then the grid display that comes, shows all the data. So the grid display is displaying the dynamic output table contents correctly.
    But the same output table isnt getting displayed in list display.
    Any pointers?
    Thanks & Regards,
    Sonali Gupta.

  • Displaying a dynamic image using a PDF file.

    I am trying to find a way to display an image dynamically in my report.  The image happens to be .pdf  I have Crystal Reports  XI and I have the graphic location formula completed "
    10.93.138.250\Production\ProdOut\00\" & {Order_Record.URN_text} + "_p1.pdf" however it tells me PDF is not supported.  Is there a way around this?

    I have to agreed that what you are saying appears to be true from my attempts at getting .pdf files to work dynamically.  Using .bmp and .jpg files seems to work just fine but not .pdf, .xls, or .doc.
    In the Users Guide, in chapter 16, in the section titled "Working with static OLE objects" - it only talks about the picture type formats you mentioned and metafiles.  Later in this section is where it explains how to make a static OLE object dynamic.
    While it doesn't specifically say it won't work for other types - it sure doesn't seem to.  I see no reason why this should be true however!  Certainly Crystal appears to be set up to allow this and the fact that the objects are not images shouldn't matter.  Why is there a picture tab and a conditional formula button next to the graphic location label on the object if it can't be used?
    I'm trying to do something similiar to Carey.  I have maps to customers in a customer list and they are in .pdf files.  The location of the map is stored in the database.  I'm putting together a report of service calls and I want to print the map with each call.  It looks like I'll have to convert several thousand .pdf files to .jpg - that should be fun!
    Any chance this limitation will be eliminated sometime soon...

  • Dynamic site using Paypal

    Can anyone recommend a tutorial which will help me set up a dynamic site using Paypal?
    I have some - although not a lot - of experience with php and mySql, and have set up simple sites using Paypal buttons - I really want to learn to combine the two.  I'm having trouble finding anything I can understand on the Paypal site, and googling it brings up such a lot of (mostly out of date) tutorials I don't know where to start.
    Thanks,

    BCDoherty wrote -
    All the PayPal button does is to take the data that's already on the
    page for that item and send it to be processed, in this case by PayPal.
    There is no magic here and no extra DB on that end of things.
    On a database driven site where everything is generated dynamically for the page, you cannot use a generic code as items such as - product name, price and product code will be different for every item, this means storing that info in the database.
    However, one does need a DB set up to handle the customer data - name,
    address, etc. BUT NOT credit card info, as well as the details of the
    order itself. Also, a single order may consist of a number of items.
    Not required, all this is handled by paypal, and one can set-up a shopping cart if required using paypal, (especially useful for beginners). Storing such things as name and address also requires the site to comply with data protection legislation, (I know most do not, but that is no excuse).
