A JDeveloper Beginner question

Hello all,
I've just received JDeveloper + Oracle8i, and tried to test the bc4j sample located in its samples directory (the auctions sample).
While compiling the jsps.jpr component, I got the following error:
Error: (0) cannot access directory oracle\jbo\common\appmgr; verify that directory is reachable from classpath and/or sourcepath.
What is JBO and how can I install it?
Please be patient with me, as this world is really new to me :-).
Thanks,
Uri

Hi..
This #{bindings.Commit.execute} will commit whole Application module(AM).That means All altered ViewObjects in that AM will be committed.If you need to Commit a ViewObject you can do it in Application ModuleImpl.
VO.getDBTransaction().commit();

  • Beginner Question

    Hello all, hopefully I have posted this to the correct LiveCycle board!
    I'm new to Acrobat and LiveCycle in general. I'm working out of windows LiveCycle Designer 8.x  and my question is as follows....
    I'm working off of the "Quote" Form Template and what I am looking for is a way to make the rows of the Table expand as needed.  I will be converting this Template into a "Purchase Order" form, and there will be many occassions where I will need to increase the table rows - perhaps onto a second or even third page - due to the volume of different items I will be seeking prices on at a given time.
    Long story short I would like to take this "QUOTE" form template and make it such that if needed, I can expand the table size one row at a time, pushing the content beneath (Comments, subtotal, etc) onto the next page....
    Hoping I have explained my query well enough,  Could anyone provide me a solution or point me in the correct direction?
    Many thanks!

    As a followup, so as not to clog the board with numerous threads I have another beginner question
    For the sake of hypotheticals I am creating a dynamic PDF form.  This pdf is a Purchase Order Form, with a table in the Body that will expand/contract as the form user needs.  (EXA-  Default table size is 5 items, however user is creating an order for 12 items, he/she can increase the table rows to desired capactiy.) It will be a very simple layout. All data for the form will come from manual entry, no XML data binding going on.
    My new question is as follows:    Is there a way I can have this user's Adobe reader or Adobe acrobat software remember previous data entries, so that if 4 weeks after ordering widget X he/she needs to place another order for widget X, the software will autofill the table as he/she types into the table cell?
    This would be similar to how Excel will start to autofill if it recognizes a previously entered value from some other cell in the worksheet (workbook?)
    EXA-
    [NAME]   [MODEL]   [QTY]   [PRICE]
    Widget           A            433        $30.00
    Would it be possible for the software to notice that I'm typing the word "widget" somewhere after typing "wid" ???
    Many thanks for any and all followups, I'm a teenager trying to help out in my father's small business. They are in the darkages here and I'm doing my best to self teach.
    Thanks.

  • Beginner question: Can I apply one formula to all cells in a column?

    Hi,
    I'm new to spreadsheets, so apologies for asking what is probably a very simple question.
    I want to apply a formula that divides the values in one column (W) by values in another (AX) for a table containing 3000 rows, and outputs the result for each row into the appropriate cell in the new column I've created.
    Numbers 09 'help' hasn't helped to this point.
    Thanks in advance for any assistance.

    Besides Numbers '09 Help there are two other useful resources available in the Help menu: the Numbers '09 User Guide and iWork Formulas and Functions Help.
    For "Beginner questions," my first choice would be the User Guide. For the specific question you asked, a quick scan of the chapter on "Using Formulas and Functions" (pp 83-96) will provide some useful information. Start in the neighborhood of page 93.

  • Beginner question regarding 32-bit mixing and mixdown workflow

    Hello
    I have a beginner question regarding 32-bit mixing and mixdown.
    If I edit some 16Bit, 44.1kHz Stereo WAV Files and put them into multi-track view to do crossfades, how should I do the mixdown?
    Audition shows me in multi-track view, that it is doing 32-Bit mixing.
    Can I just mixdown to 16Bit, 44.1kHz Stereo without any dithering (as the files are 16Bit, 44.1kHz Stereo to begin with), or will I lose quality that way?
    I will be performing a normalization to 96% to the mixdown and then split to tracks in Audition, as in the end I want to to have an audio CD.
    I guess I could mixdown to 32Bit, then normalize and in the end save back to 16Bit, 44.1kHz Stereo WAV (with dithering, I suppose?), but I want to avoid any unnecessary converting steps.
    Greetings

    Any time you do any processing on a 16bit file in 16 bit only it will degrade the audio slightly due to rounding of the calculations. Working in 32 bit floating point (Audition's default) takes account of all bits generated due to processing.
    So it is always best to work in 32 bit, even if your originals were 16, all the way through until the last stage of saving the files for CD burning. Any losses due to conversion will be insignificant against those due to working 16 bit.

  • Beginner question - how to efficiently check if a photo is part of the selection

    Dear all,
    Sorry for this beginner question, however I don't know how to solve it and I'm sure that there is a quick and easy answer to this:
    My target is to get all the "heads of stack" (photos with Position 1 in stacks) of the selection ("photos" below).
    for i, photo in ipairs( photos ) do
      local photoName = photo:getFormattedMetadata('fileName')
       if photo:getRawMetadata( 'isInStackInFolder' ) then
       --Photo is in a stack
            local photoHeadOfStack = photo:getRawMetadata('topOfStackInFolderContainingPhoto')
            local stackPos = photo:getRawMetadata( 'stackPositionInFolder' ) -- get the position in the stack
            local photoHeadName = photoHeadOfStack:getFormattedMetadata('fileName')
            app:logVerbose("Photo nb ^1, name ^2 is in a stack with the position ^3", i, photoName, stackPos)
            if stackPos == 1 then
            -- photo is master of the stack
                 stackTop[#stackTop+1]=photo
                 app:logVerbose("Photo ^1 is top of the stack ^2", photoName, #stackTop)
                 -- check if couple if correct
            elseif photos.photoHeadOfStack then
                 app:logVerbose("Photo ^1 is in a stack, but not on top. Top of the stack already selected", photoName)
            else
                 stackTop[#stackTop+1]=photoHeadOfStack
                 app:logVerbose("Photo ^1 is in a stack, but not on top. Top of the stack ^2 - ^3 ", photoName, #stackTop, photoHeadName)
            end
      end
    end
    In the if structure in the middle checking the Position in the stack, if the Position is not 1, I would like to check if the photo heading the stack ('photoHeadOfStack') is part of 'photos'. I tried 'elseif photos.photoHeadOfStack then' and 'elseif photos[photoHeadOfStack] then' but it doesn't work ->this elseif is never true even if 'photoHeadOfStack' is part of 'photos'.
    Is there anyway to have this check done without checking "manually" photos ?(via for example a for Loop)
    I'm sure that Lua proposes this, but I don't know how...
    I thank you for your Support!

        --[[ This code creates "stackTops", an array of LrPhotos that are the
        tops of all the stacks containing photos in the array
        "photos". ]]
    stackTopSet = {}
    for _, photo in ipairs (photos) do
        local stackTop = photo:getRawMetadata ("topOfStackInFolderContainingPhoto")
        if stackTop ~= nil then stackTopSet [stackTop] = true end
        end
    stackTops = {}
    for photo, _ in pairs (stackTopSet) do table.insert (stackTops, photo) end

  • Beginner Question: SA520 Admin access through WAN port

    Dear all,
    I've a beginner question regarding my brand new SA520: How can I configure the box so that I'm able to access the admin GUI not only through the LAN ports but also from the WAN ports?
    I tried already to allow inbound traffic to the firewall's internal IP address (not sure if done right, so) and granted the admin user access profile from WAN and LAN: I can access the box from the LAN but not from the WAN. Any ideas?
    Thanks,
    Eric
    PS: Yupp, I know that it's not a good idea to expose a FW admin GUI to the WAN - but this is only a lab environment

    Go to Administration -> Users.
    click on the 'Edit User Policies' 'Login' button.  It's there you can enable WAN access.

  • Beginner question - using pre for flexibility in text?

    Hi,
    Apologies for the beginner question, but I am struggling to work out whether it is more sensible to use <pre> in all my texts, as it seems more flexible.
    It seems that when I use <p> - paragraph - I can't use multiple space bars to align certain bits of text, but more disruptively I have gaps between text when I press Enter (I guess this defines the paragraph, but isn't always wanted).
    Well, basically, <pre> seems more flexible, but it behaves strangely sometimes. What do other people use?
    Many thanks!
    Ivan Reshetilov
    http://www.ivanreshetilov.co.uk

    Hi Ireshe, just a beginner like you.  Have never heard of <pre> tags, use <p> tags.  If you hit SHIFT enter after a sentence this puts in a <br> tag or line break which basically leaves a blank line between text.
    If you add     &nsbp;    or lots of them between words this gives you an extra space between letters.  How all your paragraphs sit on the page is defined by CSS.  E.g.
    p {
         margin:0;
         padding: 5px 0 0 10px;}
    This would place all text within <p> tags on your page, with a 5px gap at the top, no space to the right or bottom and 10px space to the left.  Hope this helps, good luck!

  • Beginner question: Configure Tomcat for JAAS?

    Hi,
    This is a beginner question :-(. I'm trying to get JAAS to work on my Tomcat (6.0.12) installation. I used code from a Javaworld article (http://www.javaworld.com/javaworld/jw-09-2002/jw-0913-jaas.html)
    Of course I had to configure my Tomcat to work together with JAAS. The document I used is: http://tomcat.apache.org/tomcat-6.0-doc/printer/realm-howto.html
    According to the Tomcat doc I have to do the following steps before I can use JAAS to authenticate a user:
    1. Develop your code. Place the compiled classes in Tomcat's classpath
    2. Setup a login.config file for Java, and tell Tomcat where to find it (set JAVA_OPTS)
    3. Configure the JAASRealm in your server.xml
    1 Develop code: I use the following classes:
    PassiveCallbackHandler.java
    RdbmsCredential.java
    RdbmsLoginModule.java
    RdbmsPrincipal.java
    These classes I put in the package rdbmsjaas.
    In the %CATALINA_HOME%/webapps/Javaworld_Jaas/WEB-INF/lib directory I created the rdbmsjaas.jar file.
    The jsp is called jaas.jsp, and is stored in %CATALINA_HOME%/webapps/Javaworld_Jaas
    2. Setup login.config
    In %CATALINA_HOME%\conf I saved the file Javaworld_all_that_Jaas.config, containing:
    Example {
       RdbmsLoginModule required
       debug="true"
       url="jdbc:mysql://localhost/jaasdb?user=javauser&password=javadude"
       driver="com.mysql.jdbc.Driver";
    };I created an XP Environment Variable JAVA_OPTS with the value <-DJAVA_OPTS=-Djava.security.auth.login.config==C:/Program Files/Apache Software Foundation/Tomcat 6.0/conf/JavaWorld_All_That_Jaas.config> (excluding < and >)
    I used the fully qualified address, instead of $CATALINA_HOME/conf/JavaWorld_All_That_Jaas.config. I think XP balks when it sees $CATALINA_HOME).
    3 Configure JAASRealm in server.xml
    In %CATALINA_HOME%\conf\ I changed web.xml. I added the following lines:
          <Realm className="org.apache.catalina.realm.JAASRealm"
                 appName="jaas"
                 userClassName="rdbmsjaas.RdbmsPrincipal"
                 debug="99"
           />If I run the jsp from http://localhost:8080/JavaWorld_Jaas/jaas.jsp, I can enter my username/password, but when I click the Submit button, I get:
    Caught Exception: java.lang.SecurityException: Unable to locate a login configurationWhere did my configuration go wrong?
    Abel

    You will need a JSP/servlet engine such as Tomcat - Apache alone won't do it.
    I haven't seen any tutorials on set-up but the Tomcat documentation includes info on how to link to Apache. There are also books you can buy - check out the online book stores such as Amazon.
    There's also a lot of info on this forum.

  • Beginner question: creating my own virtual instruments from samples

    Hi, I have a beginner question. I'd like to make a click-track, but I want to use my own sounds, either recorded or from the internet. Can I do this with Logic Express 7, or do I need Logic Pro 7 and the EXS24?
    Thanks,
    Ryan

    I think you can do it, but it might be a pain.
    You could import a sample of a single click and just paste it into every beat on the Arrange Page.
    Other than that, you might need the sampler included with Logic Pro

  • Beginner question: support to HTTP POST om Oracle AS

    Hi!
    I don't know if this is a suitable forum but since i use JDeveloper and Oracle BPEL I'll try my luck here :).
    I have a Java web application built in JDeveloper and a couple of BPEL processes.
    In these processes I use Java embedding (a piece of Java code) that opens a connection to a given URL and post a XML message to this URL. I didn't have much problems creating these processes.
    Now I have to provide a support to HTTP POST on my side. Since web application and services development are quite new to me I hope someone can point me the right way to do this. The requirements I have are: I can have a single URL to which the http POSTs will be issued.
    If I understand correctly I cant use a web service since I have to enable different types of XML posts. What are my options? Can I create some kind of listener for http POSTs? Can I create a jspx that will 'wait' for http posts and than call some of mine BPEL processes? Is there a way to create a BPEL process that 'waits' for http POSTs? Are there other options.
    I'd really appreciate any pointers on this.
    Regards,
    BB.

    Frank,
    I've tried creating a Servlet listener that implements HttpSessionListener interface. Now I have two methods, sessionCreated and sessionDestroyed but I don't know where to go next. I can't find any documentation on this issue yet.
    Should I create a jspx page with form node that has method attribute set to POST or maybe I don't even need a web page? I already have a login page that has a form with method set to POSt, will this pose any kind of troubles for me?
    I apologize for any stupid questions but as I said I have no experience in doing this and las couple of days I'm searching and reading different documentation on this topic so any more pointers would be appreciated.

  • Jdeveloper Debugging Questions.

    Hi All
    I have a customer who has logged a SR with the following questions, may I please request one of developers to review these questions
    Problem-1
    When running OA framework pages from JDeveloper, is there a way to get the personalizations on the pages availabe while debugging. The pages I am able to run do not have the personalizations so cannot accurately run the page.
    For iProcurement,I downloaded the pages from $ICX_TOP/mds. However the customizations done on these pages at the site/responsibility level are stored under the customizations path so not sure how to get these reflected on the downloaded seeded framework page.
    Problem-2
    I have a Descriptive Flexfield added on the OA Framework page. This DFF is comprising of multiple segments. I need to know a way to get the number of the child segment. [Descflex1, Descflex2 etc] to control the behavior of individual segment. Example - We have a DFF on the PO Requisition Lines comprising of 7 segments. I want to know how to get the positions of individual 7 segments.
    Cheers
    Roy

  • Beginner question about granting access rights

    Hi, am a total beginner, just a very simple question. I have created a number of tables with my admin account that I would like user accounts to be able to see (they should only be allowed to see these few tables)
    I then created a user account called EDWARD with just the basic connect access right (I don't want them to be able to create/delete tables etc, just to be able to query the tables I have created above and to add rows to these tables)
    Google searching has lead me to the grant statement, so I tried this from the admin account:
    grant select, update, insert on CUSTOMERS to EDWARD;
    This statement executes correctly but when I log in the EDWARD account I cannot do any of these things, instead I get the error: ORA-00942: table or view does not exist
    Any ideas?
    Thanks

    >>Would it be better to create a separate account called 'ADMIN' perhaps that I use for
    my application admin and then grant them appropriate access to confidential tables
    rather than logging them in as the SYSTEM?
    Yes, this is what I would advise, since SYSTEM (like SYS and several others...) is not user like other, it's better do not work and create object under this one. Keep it for Oracle administration usage only, not for application administration, create your own schema for this.
