Checkbox column in a table problem in getting and setting boolean values

hi Im a newbie in jdeveloper oracle 10g. can anyone help me with jdeveloper adf swing?
I have a table, one of its column is a checkbox that retrieves its value from an oracle database. Oracle doesnt have a boolean datatype. In java, when a column in jtable has a boolean datatype the column automatically becomes checkbox.
I dont know how to manipulate the select and deselect of checkbox.
please met me know.
thanks.

Hi thanks for the response, i already do that but im having problem with my view (user interface) it seems that its not working.
i have his code in my view -> Pa.java
        jTableCheckClearing.setModel((TableModel)panelBinding.bindUIControl("CheckClearingView",
                    jTableCheckClearing));
        ABSIJTableWrapper.adjustColumnPreferredWidths(jTableCheckClearing);
        TableColumnModel colModel = jTableCheckClearing.getColumnModel();
        colModel.getColumn(0).setHeaderValue(new String("Type"));
        colModel.getColumn(1).setHeaderValue(new String("Description"));
        colModel.getColumn(2).setCellRenderer(new ABSINumberRenderer());
        colModel.getColumn(3).setHeaderValue(new String("Status"));
        colModel.getColumn(4).setHeaderValue(new String("Default"));
How can i see the new column that i added in the view?

  • Problem in getting and setting focus on an item in j2me

    hi all,
    i wanna get focus on an item when a user selects it can any one tell me is there any class in j2me for doing so
    thx

    Hi,
    :. It's not exactly what you want, but it can bring some light to the
    matter.
    const char *JstrToChar( JNIEnv *env, jstring jstr )
      if( jstr != NULL ) return (*env)->GetStringUTFChars( env, jstr, NULL );
      else               return NULL;
    int JarrLength( JNIEnv *env, jobjectArray oarr )
      if( oarr != NULL ) return (*env)->GetArrayLength( env, oarr );
      else               return 0;
    void freeJstr( JNIEnv *env, jstring jstr, const char *p )
      if( p != NULL ) (*env)->ReleaseStringUTFChars( env, jstr, p );
    JNIEXPORT void JNICALL showArray( JNIEnv *env, jobject self, jobjectArray jv_oarr )

      jobject      jv_obj;
      int           iLen;
      const char      *content;
      iLen = JarrLength( env, jv_oarr );
      if( (jv_clsstr = (*env)->FindClass( env, "java/lang/String" )) != NULL )
        for( iCt = 0; iCt < iLen; iCt++ )
          jv_obj = (*env)->GetObjectArrayElement( env, jv_oarr, iCt );
          if( (*env)->IsInstanceOf(env, jv_obj, jv_clsstr) )
            content = JstrToChar(env, (jstring)jv_obj);
         fprintf( stderr, "Just testing. Param[%i]=%s\n", iCt, content );
            freeJstr( env, (jstring)jv_obj, content );
      else fprintf( stderr, "Error on finding class String!\n" );
    :. Meanwhile inside Java code...
    public native void showArray( Object[] arr );
    :. I sent an array of Objects instead of Strings, as you can see.
    Also the above sample was modified in a hurry, so it can bring small
    errors of typing. Hope it helps.Roque

  • How do I get and set column attributes in a table or a treetable with Java?

    Using 11.1.1.4.0
    Hi,
    How do I get and set column attributes in a table or a treetable with Java? For a simple example, say I have a table and want certain roles to see all columns (including address), and other roles can see only certain columns (no address). In a Java method, I want to test if a table's column visible attribute is true and if so, set it to false before rendering it.
    Thanks in advance,
    Troy

    Hi,
    this use case would be a perfect example for using seeded MDS customization. Instead of checking what users are allowed to see or not upon rendering time, you have a customization class and thus the framework doing this for you.
    http://www.oracle.com/technetwork/developer-tools/adf/learnmore/31-mds-sample-169173.pdf
    In this paper and sample, specific users see different layouts. It also contains a customization class that shows how this can leverage ADF Security

  • Get and Set Parameter ID in BDC Call transaction

    Hi all
    I have written this BDC program to run a transaction eg33  to install meter. After meter get installled System generates  Device location number.

    i think there might be some time gap between CALL TRANSACTION and GET PARAMETER ID.....,that is to say,the new No. has not been generated and what you fetch is an old No..
    i think you should use the "CALL TRANSACTION" like the following one:
    CALL TRANSACTION 'EG33' USING BDCDATA MODE 'A'  UPDATE 'L'  MESSAGES INTO IT_MESS .
    then i think you can get the right value.
    P.S: the different update model(from SAP document)
           upd Effect
    "A"   Asynchronous update. Updates of called programs are executed in the same way as if in the             COMMIT WORK statement the AND WAIT addition was not specified.
    "S" Synchronous processing. Updates of the called programs are executed in the same way as if in the COMMIT WORK statement the AND WAIT addition had been specified.

  • How to get Document Set property values in a SharePoint library in to a CSV file using Powershell

    Hi,
    How to get Document Set property values in a SharePoint library into a CSV file using Powershell?
    Any help would be greatly appreciated.
    Thank you.
    AA.

    Hi,
    According to your description, my understanding is that you want to you want to get document set property value in a SharePoint library and then export into a CSV file using PowerShell.
    I suggest you can get the document sets properties like the PowerShell Command below:
    [system.reflection.assembly]::loadwithpartialname("microsoft.sharepoint")
    $siteurl="http://sp2013sps/sites/test"
    $listname="Documents"
    $mysite=new-object microsoft.sharepoint.spsite($siteurl)
    $myweb=$mysite.openweb()
    $list=$myweb.lists[$listname]
    foreach($item in $list.items)
    if($item.contenttype.name -eq "Document Set")
    if($item.folder.itemcount -eq 0)
    write-host $item.title
    Then you can use Export-Csv PowerShell Command to export to a CSV file.

  • How do I get and set cookies with JSF?

    How do I get and set cookies in a JSF managed bean?
    Regards,
    Al Malin

    Below is how I did it...I am receptive to improvements.
    FacesContext facesContext = FacesContext.getCurrentInstance();
    HttpSession session = (HttpSession)facesContext.getExternalContext().getSession(false);
    HttpServletRequest request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
    HttpServletResponse response = (HttpServletResponse)facesContext.getExternalContext().getResponse();
    String cookieName = "myCookieName";
    Cookie requestCookie = null;
    Cookie[] cookies = request.getCookies();
    logger.info("looking for cookie...");
    if (cookies != null)
    for (int i = 0; i < cookies.length; i++)
    if (cookies.getName().equals(cookieName))
    requestCookie = cookies[i];
    logger.info(cookieName + " = " + requestCookie.getValue());
    logger.info("done looking for cookie");
    Cookie responseCookie = new Cookie(cookieName, "myCookieValue");
    responseCookie.setPath("/");
    response.addCookie(responseCookie);

    Hi

    please help me out.

    You can use the call library function node. Once you drop it on your block diagram double click it and you will be able to select the dllyou want to use. Choose kernel32.dll and you will see methods listed called getsystemtime and setsystemtime. Use those

  • Code for replacing 'get' and 'set' method

    Hi,
    I was a struts programmer but now i am a jsf programmer :-)
    I was able to do the following with struts but no with jsf...
    The following code in struts allowed me to have no 'get' and 'set' method in the javabean for a property (for example, the property 'name'):
    ValueStack valueStack =ActionContext.getContext().getValueStack();
    valueStack.set("name", "John");
    ActionContext.getContext().setValueStack(valueStack);In the jsp, using the corresponding label to retrieve the 'name' property, returned value 'John'.
    Is there something equivalent in jsf?

    Hi, see on here.There are solutions for JSF, JBoss Seam: [Solutions for Java, JSF, JBoss Seam and Flex|http://flextrick.blogspot.com/]

  • Why do we need get and set methods?

    It is considered good design practice to keep all class data private and
    provide get and set methods for accessing the data in a controlled
    manner.
    So, instead of directly accessing the class data, you use getter and setters.
    I do not really feel the need to use get and set methods.
    How does that achieve encapsulation when ultimately the class data is being exposed?

    A couple of reasons why to use get and set:
    1. For example you can set an int value for month, if a user sets this to somting
    higher than 12 (or 11 if it's zero based) you want to handle that by either
    throwing an exception or adding a year for every time it can be devided by 12.
    If you dont do it in set you'll have a whole bunch of methods that might need to
    correct the value before retreiving the eventual date.
    2. If for some reason you have security set up for certain values you can
    implement this in the get method. When this is done somewhere else you have
    a whole bunch of methods retreiving the info in other classes that need to check
    first. (a canGet method could allso be used). Another good reason to use get
    is when the information needs to be converted depending on the consumer
    calling the get method.
    3. If any logic in 1 or 2 changes you'll have a bunch of code to change.
    If you feel there is no need to implement any security, error handling (on
    compiling because get and set might throw something) or validation when
    setting/getting these values there is still the argument of readabillity.
    Eclipse has a feature that will generate getters and setters for you so it's not
    like there is a lot of extra typing involved.
    Got interupted whyle typig so sorry to repeat any answer given before.

  • Bug in "Get and Set Time.vi" example for RT systems

    There is a bug in "Get and Set Time.vi" that ships as an example in the "NI System Monitor" package.  The routine does *NOT* return the hour correctly.
    Note the string "%#H:12:39.371" as the time of day.  That should be 09:12:39.371 as it was 9 AM at the time.
    Mac OS X 10.8.5
    LabVIEW 14-64bit
    NI System Monitor 14.0.1
    Pharlap RT PXI embedded system version 14.0 updated.
    NOTE: it is odd that the default "New Time" has #H as the hour but that is hard wired into the VI as a sentinel case.

    Rahul,
    It may be only in the Mac OS X code base.  But since it is one of those annoying locked VIs I can't tell.  Now of course this is locked because communication with the RT system is so sensitive or just plain messy.  My guess is that if I thow wireshark at it I can tell you what is inside and it shouldn't be that secret.
    But let me know what you find running under Mac OS X.

  • After adding one column in a table can't get the header line

    hi all,
    i have make a SMART FORM which was working perfectly.Now the requirement of user is to add one column in my table at smart form which i did and after modification i execute it it give me data as well but issue which i'm facing is that the TABLE at smart forms in which i have add one field is not displaying the HEADER LINE which i have define with SELECT PATTREN option.
    Thanks & Regards,
    sappk25

    Hi,
    Have you created the Header Text? If yes, then might be the case that your smartforms
    table which was already created is with Multiple Line. Check weather you have added
    customer field in Header Line or Not?

  • UIX Problems Trying To “Get” and “Set” Values To messageTextInput Objects

    I have created an input UIX form in the Struts Page Flow Diagram using the Page Forward Action and dropped two views from the Data Control Applet as Input Forms. I am trying to �get� the value from one bound messageTextInput object in view1 to set the value of another bound messageTextInput object in view2. I do not know how to reference the bound messageTextInput objects on the UIX page.
    Any suggestions?
    Thank you,

    Hi Alain,
    Initially it is little bit confusing.
    To get the value:
    wdContext.node<nodename>().get<nodename>ElementAt(i).get<Attribname>();
    To set the value:
    wdContext.node<nodename>().get<nodename>ElementAt(i).set<Attribname>("value");
    First check the cardinality of the node.If the cardinality is 0..1 or 0..n then you need to create an element and add it to the node.
    IPrivate<viewname>.I<node>Element ele = wdContext.create<node>Element();
    ele.set<attribname1>("value");
    ele.set<attribname2>("value");
    wdContext.node<nodename>().addElement(ele);
    If the cardinality is 1..1 or 1..n then 1 element is created by framework. You can use that element. If you want to add more elements just use the above code.
    2.IWDAttributeInfo attInfo= wdContext.node<Node>().getNodeInfo().getAttribute(<Attribname>)();
