Problems with LOV'S in Web

Hi,
I have a problem with LOV'S in Web. I've Forms Server in two servers. User's work with them.
When I push the LOV'S keys, the session is killed.
Please Help Me
Thaks

You need to break the problem down. Do you get the same problem with a one field Forms launching and LOV?
1) What key did you use?
2) What version of Forms
3) What OS?
4) Did you try on another OS?
5) Does it work client server?
1) I use Ctrl + L
2) Forms Deleveloper 6i Release 2
3) Windows 2000 server
4) No
5) Work OK
Why the session is killed ????
Thanks

  • CurrentUISkin  problem with LOVs

    Hello JheadStart Team
    I'm using user selected skin by using menuAdminService and setting adf-faces-config to
    <skin-family>#{jhsDynamicMenu.currentUISkin}</skin-family>
    but i have problem with LOV's:
    Error getting property 'currentUISkin' from bean of type oracle.jheadstart.controller.jsf.bean.DynamicMenuBean: java.lang.RuntimeException: Cannot find JhsModelService, Binding container UsersPageDef data control data provider is null
    Kind regrads

    I was able to reproduce the problem. We will provide a fix in the next patch release.
    For now, you can apply the fix yourself as follows:
    - create a subclass of oracle.jheadstart.controller.jsf.bean.DynamicMenuBean
    - Add member variable to this class:
    private String myCurrentUISkin;
    - Override method setCurrentUISkin as follows:
    public void setCurrentUISkin(String currentUISkin)
    this.myCurrentUISkin = currentUISkin;
    - Override method getCurrentUISkin() as follows:
    public String getCurrentUISkin()
    try
    if (JhsModelServiceProvider.getInstance().getJhsModelService() !=null)
    setCurrentUISkin((String) getCurrentModule().getAttribute(SKIN_ATTRIBUTE_NAME));
    catch (Exception e)
    // do nothing, return "previous" currentUISkin;
    return this.myCurrentUISkin;
    - Make a custom template for JhsCommonBeans.vm. In this template replace oracle.jheadstart.controller.jsf.bean.DynamicMenuBean with your own fully qualified class name
    - Set the JHS_COMMON_BEANS template key at service level to your custom template
    - Generate again.

  • Problems with error-page in web.xml and page caching

    Having a few problems with error pages and web.xml with browsers caching the error pages and strange errors coming out of weblogic.servlet.intenal.WebAppServletContext
    I'm trying to set a web app up so that all http errors and all exceptions are routed thruogh predefined resources. For now, I'm simply send 400 errors to 400.html and the ServletException, IOException and RuntimeException to respective html pages.
    What I'm finding is that the error codes work fine but the exceptions are only be routed to the correct error page for the first call to the servlet after server restart.
    So for example, I have my servlet throwing a ServletException as a test case. The weblogic server log shows that ServletException is thrown, and the correct error page for ServletExceptions is shown.
    If I change the Servlet code to throw IOException in place of SevletException, the weblogic.log shows that IOExceptyion is being thrown (so the servlet has deployed successfully), however the Servletxception error page is shown on the browser.
    I'm using IE6 and I've changed the setting such that a new page is requested every time using the tools-internet options-temp internet files-settings option to "check for new versions of stored pages: Every visit to the page".
    Despite this, the servlet exception error page still appears.
    If you clear the cache from the temp intenet files->delete files IE option, the correct errror page will be shown so it appears that the browser cache is being used after all.
    everytime I delete the temp intenet files I get the correct error page on the first request after but then not after that.
    I have implemented the service method for this test to throw the exceptions - does this make a differecne?
    As a test, I have moved the imlpementation to the doGet method instead bu I now get a strange eror from weblogic comlpaining about an arrayOutOfBoundsException because eror codes in the web.xml are not supported! - see error above.
    Any help is appreciated

    After further investigation: -
    There are no problems with error pages based on error codes, only error exceptions.
    As a test case, I have a service method in a servlet throwing either one of the three exception types that servlets can throw (Runtime, Servlet & IO) the following rules apply. The exception to be thrown is hardcoded and is changed and the web app rebuilt each time. The correct web.xml has been deployed to the app server (checked through console). the webapp is being redeployed correctly - this can be seen in the weblogic log, where the correct exception is reported.
    I am using WLS 8.1, Servlet 2.3, JDK 1.4.1_02
    In all cases, the weblogic log reports that the servlet is throwing the exception as expected.
    Despite having set error-page for exception javax.servlet.ServletException, the exceptions are diverted to the error page that has been set up for http error code 500
    The error page for ServletException is therefore never reached.
    I have the browser set to request pages every time it is asked.
    Once the servlet has thrown an IOException, the only way to get the browser to report an IO or Runtime exception error-page is to clear the browser cache. Restarting the server has no effect.
    Once the servlet has responded with ANY exception, it is not possible to get it to report a ServletException (which is incorrectly reported as a 500 anyway) unless the cache is cleared. Restarting the server has no effect.
    In the case where the servlet throws ServletException, it has no root exception. The servlet 2.3 spec states that if ServletException is thrown but cannot be found in the error pages, the root excpetion will be extracted and the error page list traversed again. Knowing that the RuntimeException error page is correct shown when RuntimeException is throwm, I have nested this inside the ServletException, however error page for http error 500 is still shown.
    I don't believe this is a WLS 8.1 problem, as the console shows that the correct exception is thrown each time. this is backed up by the fact that the correct exception page is thrown when the cache is cleared regardless of what exception was previousdly thrown by the servlet. This excludes ServletException which is always incorrectly thrown as a 500.

  • Problem with win2000sp3 and Java web start

    I have JRE and Java web start (1.2.0_01, build b01) which come downloading file j2re-1_4_1_01-windows-i586-i.exe from sun.
    I have win2000pro running on my PC.
    I had updated win2000 to service pack 2 and everything was fine.
    Now i decided to update to service pack 3 (in the process I also updated other components) from Microsoft and:
    1) Java applets seem to be running fine within i.e.
    2) If i try to run an application from java web start my PC freezes and I have to restart it.
    3) Staroffice 6.0, which runs on Java, seems to be fine.
    I reinstalled both sp3 and jre etc, with no result.
    Is this a known problem?
    Thanks to all.
    Maurizio

    I suspect that you have hit a known problem with Swing on Java 1.4.1 with buggy video drivers. Do you have an ATI card? They are the worst offenders. ATI released new drivers for its Radeon line today. They fix the problem.

  • Problem with '-' (dash) in BEx web analyzer

    Hi All,
    we are having a strange problem with 0BPartner and 0Material. Our BPartner and Material have '-'(dash) sign as part of key. While selecting this BPartner/Material in Bex Analyzer, we do not have any problem, but when we try to select the same Bpartner/Material in BEx Web Analyzer, it puts an escape char in from of the dash. For eg:
    If i select the Bpartner "1234-5467" then in Web Analyzer selection box, it is displayed as  "1234\-5467" in the selection screen.
    If i do a search on 1234-5467, it returns zero value.But if i do a search on 1234\-5467, then i get the search hit.
    If i enter the Bpartner in the selection window directly and If i do not put the escape char, then it considers the input as range 1234 - 5467 and returns me no value in the report output.
    Has anyone had this type of issue? Please respond.
    Thanks
    Niveda

    Thanks Olivier,
    Sorry if you had misunderstood my question. They are 2 different Info objects. and i am having problem searching values in each one of these info objects.
    Let me explain it with an example.
    Scenario:
    Let say company defines material in the following format.
    "123", "456", "788", "345"....etc.
    And I have a report which has material as input selection.
    To run this report with single material i enter "123" in the selection screen
    To run this report with a range of materials, I need to enter 123 - 456 in the selection.
    I have no Issues
    Scenario 2.
    Consider a case if the materials are defined in SAP as "001-1234", "987-234"
    "123-234" etc.
    In this scenario, to run the same report for 1 material, i will enter 001-1234. But now the question is how will BW system interpret this material entry.
    Is this 1 single material(001-1234) or a material range (001 - 1234)??
    We have issue here. The system considers this material "001-1234" as a range (001 to 1234) instead of single material and gives me zero output.
    Any help??

  • Problem with Dates in the Web Intelligence

    Hello Everyone,
    I am facing a problem with the Web Intelligence Report, in the universe there is a Date field (L01 Date and L01 Date Key). In the report Web Intelligence when i use L01 Date Key it works fine (like 10/07/2010), but when i use L01 Date it shows a Strange Date like 31/12/69. I´ve already tried out with another infocube and query, but the value is the same (31/12/69).
    Does anybody have any idea ?

    Hi,
    The problem is coming because L01 field contains summary data of L01 filed and L01 key field contain actual value of that field.
    so date field cant be summarize so that's why you are getting an error. Please check with some non date field. hope it will work perfectly fine.

  • Problem with lovs in viewobject instances

    Hi,
    Working with Jdev11.1.1.16 ,
    Referring to  forum : Problem with Two VO's from same EO with different where clause
    I was also facing the same issue with static where condition ,using this recommended approach the issue is solved .
    The recommended approach is working fine for fetching data .
    I have create one viewObject with two viewcriteria and created two instances of viewobject in datamodel . In datamodel i have added viewcriteria too.
    But in my case, i need to populate different lovs on same attributes on both the tables (instances of same view object).
    I have added two lovs to the attribute and switch condition based on other attribute.
    While fetching, the data is coming correct and lovs are also correct but while clicking on createinsert lovs are not cuming properly .

    Hi,
    I would suggest that you post relevant pieces of code here - so that it is easier to help you.
    Just a thought:
    Please note that the event handlers may be called again while you are processing another event (there are at least some cases when this is happeneing) - this might lead to "confusing" forms.

  • Pleaseeeeeee Help - Problems with position of my web page

    Hi, first sorry on my english
    I have problem with position of my page. I had made my web page in Indesign CS5 and exported to swf file. My web page is working fine (www.igor-flytying.com) but the page is not in the middle of the web browser. How can I fix the problem????? I am a beginer in Indesign. I had try to make some changes in html file (salign) but still nothing.
    Please HELLLLLPPPPPP
    Regards
    Aljosa

    Petteri, SWFObject is much better because it loads the JavaScript so you don't see it inside the HTML page, but it still wraps the swf in a div which by default will be positioned in the upperleft of the browser window.
    This is the only way I've been able to center using SWFObject—note that it's the "flashcontent" div style that does the centering not the align embed parameter:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
    <head>
    <title>S W F | Centered</title>
    <meta http-equiv="Content-Type" content="text/html" />
    <!-- Centers the swf on the page. Note: width and height need to match the swf and margin left and right are -.50%-->
    <style type="text/css">
              #flashcontent {width: 1000px; height: 750px; margin-left: -500px; margin-top: -375px; position: absolute; left: 50%; top: 50%;}
    </style>
              <script type="text/javascript" src="swfobject.js"></script>
              <script type="text/javascript">
                        var flashvars = {};
                        flashvars.myFlashVar = "Testing";
                        var params = {}; //Embed parameters: http://kb2.adobe.com/cps/127/tn_12701.html
                        params.quality = "best";
                        params.align="t"
                        //SWFObject parameters: http://code.google.com/p/swfobject/wiki/api
                        swfobject.embedSWF("swftest.swf", "flashcontent", "1000", "750", "10.0", false, flashvars, params);

  • Problem with inbuilt Solaris Apache Web Server v 2.0.58

    Hi,
    Set-up:
    We are working on a custom application which works with the inbuilt Apache Web Server on the Sun Solaris platform. Here are the details of the versions of the various components involved:
    Apache Web Server: Version 2.0.58
    Platform: SunOS 5.10 Generic_127111-03
    Our application is in the form of a shared library(.so binary) which is loaded into the Apache Web Server by mentioning the following directive in the Apache Web Server's configuration file (httpd.conf).
    LoadModule at_module "/var/apache2/logs/sample/sample.so"
    where, sample.so is our application's binary
    and at_module is the name of the module.
    httpd.conf file has been attached for your reference.
    Attachments:
    httpd.conf - Apache Web Server's configuration file.
    sample-apache.cpp - Sample program which is showing the problem.
    httpd.h - Apache Software Foundation's file which contains the structure "request_rec" that represents the current request.
    Problem summary:
    For each request to the Apache Web server, the server maintains a table of type "apr_table_t" which contains the header environment from the request. There is a structure "request_rec" maintained in the httpd.h file:
    /** A structure that represents the current request */
    struct request_rec {
    /** The pool associated with the request */
    apr_pool_t *pool;
    /** Request method (eg. GET, HEAD, POST, etc.) */
    const char *method;
    /** MIME header environment from the request */
    apr_table_t *headers_in;
    In our case, when we try to retrieve the address of "headers_in", we get a NULL Value. Please refer to the attached "sample-apache.cpp" program. In this program, inside the access_checker() method, we try to retrieve the address of "headers_in" and get that as NULL:
    extern "C" int access_checker(request_rec *r)
         FILE * fp;
         fp = fopen("/var/apache2/logs/sample.txt", "a");
         fprintf(fp, "\n r->headers_in = %u, r->method = %s", r->headers_in, r->method);
         fclose(fp);
         return OK;
    Here is the output of the sample program after accessing the main page of the Web server:
    r->headers_in = 0, r->method = GET
    r->headers_in = 0, r->method = GET
    r->headers_in = 0, r->method = GET
    Though we are able to retrieve one member of the structure request_rec (method), we are not able to retrieve the address of the other member (headers_in).
    Observation:
    We made an interesting observation that when we used the same sample program with the inbuilt Apache 2.0.52 Web Server on Solaris, we were able to successfully retrieve the address of headers_in. Here are the details of the set-up which is working fine:
    Apache Web Server: Version 2.0.52
    Platform : SunOS 5.10 Generic_118822-30
    Thus, there is something different which has happened between the Sun's Solaris Apache Web Server's versions 2.0.52 and 2.0.58 which is making it unable to retrieve the address of the request headers (headers_in).
    I am requesting someone to kindly shed light on this difference and let us know if we need to change the way of retrieving the request headers for Solaris Apache 2.0.58.
    Thanks,
    Atul.

    The only way you can achieve it is by running the web server to listen on port 80
    Please change the port in your httpd.conf file for the webserver and restart it.
    If any other processes are running/using on port 80 on that machine, then please stop them, otherwise you will not be able to achieve your requirement.

  • Problems with LOVs

    I'm working with ADF 11g, and I have a problem when i work with LOVs.
    I have a table in my database which has a composite primary key of 4 fields (columns). I have also created a viewObject for this table and i have added a list of values to each field. After this, i created an ADF Table in my JSF page.
    When i execute my page i have problems editing and creating a register, as only the first LOV it's available. The other LOVs don't open when I select them.
    I'm working with more pages with some LOVs in each of them and they work fine. I only found problems while working with pages that have composite primary keys.
    Could you please tell me a way to solve this?
    Thank you in advance.

    In the EO and VO I've checked the option "While New" in the four fields of primary key.
    If I make AM Tester, works properly. However, in jspx page I get an error when trying to open the second LOV.

  • Problem with mime type in web.xml file

    Hi everybody,
    I actually got a problem with mime types on Weblogic 6.0 under Linux.
    I read the documentation so I added the next lines in the web.xml file in
    the WEB-INF directory of my server :
    <mime-mapping>
    <extension>
    doc
    </extension>
    <mime-type>
    application/msword
    </mime-type>
    </mime-mapping>
    <mime-mapping>
    <extension>
    ppt
    </extension>
    <mime-type>
    application/vnd.ms-powerpoint
    </mime-type>
    </mime-mapping>
    Why can't I retrieve a .doc or .ppt files with an internet browser correctly
    ? I get only text/plain ...
    Can someone help me ?
    Regards,
    Alexis Berger

    I am having the same problem with doc and xsl. I have added this
    <mime-mapping>
    <extension>xls</extension>
    <mime-type>application/vnd.ms-excel</mime-type>
    </mime-mapping>
    <mime-mapping>
    <extension>doc</extension>
    <mime-type>application/msword</mime-type>
    </mime-mapping>
    to my web.xml. I even restarted the server. I still see doc and xsl in binary.
    Is there some other setting that needs to take place?
    I am using WL6.1 with fixpack 1.
    I can see the doc and excel files in the browser if I don't go through the weblogic
    server. That just confirms it's not my browser.

    It works fine for me in 6.1 SP1.

    If the following doesn't work , can you
    <br>try application/winword instead of application/msword?

  • Problems with rounding keyfigures in Webi report

    Hi,
    we have the next scenario, we have a SAP BI connected to a Universe using XIR3.1 BO version ( with the integration kit).
    When we do a report with totals using the Webi the keyfigures results haven't the expected values, if we check the values in the cube (listcube) or by a SAP BI query we get the correct values.
    We have found that the difference comes from the moment the webi report do the rounding, when we filter the query by a excluding value it seems that the rounding is done at the level of the excluding object
    Example:
    We have the quantity sales (quantity 3 decimals) at the country level displayed without decimals, at that level the totals figures match with the data displayed in the infocube in SAP BI, when we filter excluding a customer of the country the figures don't match, the quantity sales are rounded at the customer level and then are aggregated, the customer is not displayed in the report.
      Report without excluding customer:
    WEBI report                                                             Infocube / SAP BI query 
       Country     Quantity                                                  Country     Quantity
        ES             287574                                                       ES             287574
        AD                1400                                                       AD                1400
    Report excluding customer  157
       Country     Quantity                                                  Country     Quantity
        ES             274456                                                       ES             273106
        AD                1400                                                       AD                1400
    To found were is the difference we have done a query including in the drilldown the customer, rounding at that level and doing the totals as the sum of that values we have the same values in the webi report and in the SAP BI Query and it is equal to 274456 In the other case if we sum the values of the customers without rounding and we round the total the values is the 273106.
    As the diffence it is great for the business, we need to found a way to do the rounding only in the level displayed in the report.
    We have expirience in other BO projects without sap integration and we have not found that issue, it is because that we included it in the forum of the SAP integration kit.
    Many Thanks in advanced.
    Nuria

    Hi experts!
    We have a similar problem to Núria and it persists after applying the instructions given by Stratos.
    Our scenario is BO Enterprise XI 3.1 SP2 and Integration Kit for SAP 3.1 SP2.
    I have a Universe connected to a SAP BW query 7.0. When I execute a report with WebI the results doesn't match.
    We found a problem rounding quantities. The curious thing is that only happens when the quantity is "UN". In this case rounds and truncates all decimals. So, if the Quantity is 0,45 UN in BW, in Webi report is 0.
    If the Quantity is in "KG" or "L" there aren't any problem. I've seen in the BW table SUNIT that the only difference is that the field "UN" its called "ST" in the table, what makes me think that maybe the problem is related to languages. But I have no idea.
    Any suggestions?
    Thanks in advance!

  • Problem with LOV and htmldb_custom_auth.get_username

    I have a problem with the itemtype 'select list'. Why the following code creates an 'Ora Invalid Number Error'?
    SELECT ADRESSE d
          ,KAD_ID r
    FROM   V_KUNDE_ADRESSEN_STANDORTE
    WHERE  KND_KUNDEN_NR = htmldb_custom_auth.get_username
    AND    KAD_TYP_AUFTR_BESTAETIGUNG = 1It works if I put a 'to_char' arround the KND_KUNDEN_NR. But it slows down the query and it takes up to 5-7 sec.
    SELECT ADRESSE d
          ,KAD_ID r
    FROM   V_KUNDE_ADRESSEN_STANDORTE
    WHERE  to_char(KND_KUNDEN_NR) = htmldb_custom_auth.get_username
    AND    KAD_TYP_AUFTR_BESTAETIGUNG = 1Actual I use an hidden item with &APP_USER. as default value und use it in the query.
    Is there an other, maybe better way to handle this problem?
    PS: The username is the Customer-No. an it is only numeric. A 'to_number(htmldb_custom_auth.get_username)' returns the same invalid number error.

    Andreas,
    What version are you using?
    Why don't you use :APP_USER in the where clause?
