• How to get the value of a literal XML node content in BPEL 2.0?

  Hello!

  I have a problem creating A Expression in the distribution of the XML literal one activity, I would like to help me...

  Well, I have the same activity in the 1.0 version of BPEL and is now different is BPEL 2.0,.

  I have a Web Service < WSEjecutaComandos > when having a function of controls remote that connects,

  Entries of my Web Service: "int numEquipo, String [] comandos, int numCta, int publicar, int, String date version"

  The second argument is an array of string type...

  Now in my BPEL process, I do is the following assignment:

  ************************************************************

  < assign the name = "AssignCreaPath" >

  < copy >

  < from >

  < literal >

  " < fnCRexecElement xmlns =" http://Servicios/ ">

  < numEquipo > 2 < / numEquipo >

  < comandos >mkdir etl/entries/mmkis /< / comandos >

  < numCuenta > 1 < / numCuenta >

  < publicar > 0 < / publicar >

  < / fnCRexecElement >

  < / literal >

  < / from >

  < to > $InvokeClear_fnCRexec_InputVariable.parameters < /pour >

  < / copy >

  < copy >

  (< a >concat(ora:getContentAsString($InvokeClear_fnCRexec_InputVariable.parameters/comandos),$inputVariable.payload/client:fecha)< / from >

  < to >$InvokeClear_fnCRexec_InputVariable.parameters/comandos< /pour >

  < / copy >

  < copy >

  < a > $InvokeVersion_fnGetVersionProcesoByFecha_OutputVariable.parameters/version < / from >

  < to > $InvokeClear_fnCRexec_InputVariable.parameters/version < /pour >

  < / copy >

  < copy >

  < a > $inputVariable.payload / client: date < / from >

  < to > $InvokeClear_fnCRexec_InputVariable.parameters/date < /pour >

  < / copy >

  < / assign >

  ***************************************************

  Well the conflict I have is as follows,

  previously defined an entitlement with the XML Fragment copied on the payload to the Web Service (WSEjecutaComandos), input variable

  and the XML code is copied to each of the variables,

  Then him concatenating input values (I noted in red) < comandos > with the value of 'farm' (String), and once again copy Variable < comandos > and has not had any problems

  but now with the new BPEL 2.0, I do the same thing now using literal XML (this good!) but the option to concatenate (that I've noticed in red) and copied to the same variable ( I noticed blue ), I mark the following error message:

  

  I should know, I am doing wrong, or you need to to XPath function as the value that they already have the variable < comandos > will concatenate date,

  and is the final value of my entry, my Web Service.

  must be defined as table of values of type < comandos [i] >

  define the following activities before $InvokeClear_fnCRexec_InputVariable.parameters/comandos [1],

  but it seems that this BPEL 2.0 does not respect me in the form of hooks index.

  Thank you...

  See you soon,.

  I found the solution to get the value of an xml element and it concatenated with another variable within a beneficiary.

  is:

  ORA: getNodeValue (ora:getChildElement($InvokeCreaPath_fnCRexec_InputVariable.parameters,2))

  first get the desire here in my tree xml element is position 2 < comandos=""> and then get the value of this node.

  See you soon,.

  ADF7,
  I'm not sure that understand what you're up to.
  For as far as I understand you want to get the value of display rather than the index
  I use this code

      public void StatusChangedListener(ValueChangeEvent valueChangeEvent)
      {
          BindingContext lBindingContext = BindingContext.getCurrent();
          BindingContainer lBindingContainer = lBindingContext.getCurrentBindingsEntry();
          JUCtrlListBinding list = (JUCtrlListBinding) lBindingContainer.get("Status");
          int newindex = (Integer) valueChangeEvent.getNewValue();
          Object row = list.getDisplayData(); // Wichtig um die liste zu laden!!!!
          Row lFromList = (Row) list.getValueFromList(newindex);
          Object lAttribute = lFromList.getAttribute("Value");
          String newVal = (String) lAttribute;
      }

• How to get the value of row current table when press the button submit

  Hello
  
  I want to get the current value of the SuccessionPlanId line which is part of the column in a table that is advanced.
  
  I created a (created using customization, from action through CO) button in the table as column, so each line with a single key, if I press the button of the first line means so I want to extract the first line SuccessionPlanId and if it's the 3rd way so I want to get the value of the value of the third row.
  
  How in the post of controller?
  
  Please answer soon, its urgency.
  
  Thanks in advance,
  SAN

  OK, need to go with a delicate way,

  1.) create a new table with Jdeveloper and there shud be a replica of the room once except the button submit newly added, pls note button type shud be present the type of button.

  2.) hide the existing table area and create a new stacklayoutbean.

  (3.) this stacklayout bean will have the property to extend, you give the full path of the new custom of advanced table box.

  Now you should be able to get the reference of the line during the click on the "submit" button

• Get the value of a tree

  How can I get the value of a tree node? For example, I want to it works like this:
  
  When I click on a node, I get redirected to another page, but the tree needs mark the node on which I clicked.
  When I has no links in the tree, the links are marked when I click, but if I choose a link for any node, the tree is updated.
  
  I can solve my problem? I tried with examples, but still does not work.
  
  Thank you.

  Remove the column from link to leave the node or make the URL as "#" so that the page is not reload when the user clicks on a node.

  If you have a page item say "* P100_SELECTED_NODE *" which must be set with the id of the node to the selected node.

  Now to set the P100_SELECTED_NODE
  Add the following code to the section "run when the page loads" of the tree page

    $('div.tree li a').click( function() {
      node_id = $(this).parents('li:first').attr('id');
     $s('P100_SELECTED_NODE',node_id);
     alert('Node set with new value: ' + node_id );   //for testing
    });
  

• Is it possible to get the value of the resistance of a circuit with NI USB-4065 USB without using studio measure?

  Hi, I'm working on a project where there partly to measure resistance values in different parts of the circuit. Now, the company where I work currently at wants to get the NI USB-4065 USB. I use visual studio 2005 c# to develop applications and I need to know if I needed measurement studio or are there drivers (dll) just to get the values of resistance and General measures of circuit. I have need the controls or anything, just to programatically read the NI USB-4065 USB key values when I need the application.

  Any help would be appreciated. Thank you.

  Yes, you can have several NI 4065 DMM in your system. When you use the API OR-DMM, you open the handles separately for each DMM by using its name. His name can be configured inside the measurement and Automation Explorer (MAX).

  In addition, you can go ahead and install OR DMM today. It is downloadable for free on ni.com. NOR-DMM (and most of the pilots NOR) supports the simulation. You go to MAX and create your simulated three 4065 s. Then you can start writing your program now. Since these devices are simulated, they will not return the real tensions (obviously) and that it won't react realistic hardware triggers if you use (obviously), but they are pretty close to the real deal to allow you to write a lot of code and become familiar with the API. No need to wait until you get the material - you can be really ready for it by using the simulation.

  It is possible to get this value? For example, if I want to display in a TextBox?

  I am able to get the xycursor. Which and xycursorYposition but not what I want.

  Thanks for any help!

  Here is a solution to my question:

  {

  Get xy cursor index of the point in plot
  int index = xyCursor1.GetCurrentIndex ();

  Get values at that time (in the plot)
  Double x;
  Double y;
  scatterGraph.Plots [0]. GetDataPoint (index, ByRef x, y);

  X value to the DateTime format & convert to the format of the time
  DateTime t = (DateTime) NationalInstruments.DataConverter.Convert (x, typeof (DateTime));

  string time = t.ToString("hh:mm:ss");

  }

  It is also possible for which xycursor and convert it in the same way.

• [.ini files] Get the value of multiple labels with the same name

  Hello!

  In an ini.files, I need to get the value of each tag named in a certain way in a section, but unfortunately, I have 3 or 4 tags with the same name in several sections. I don't know how to retrieve these values, the program always consider that the first tag and not others, I tried to remove each tag after obtaining its values, that he did not.

  Does anyone have an idea to solve the problem?

  Thank you!

  As you can read in my last post, you must read and throw 'x' lines:

  OpenFile)

  Skip lines

  for (i = 0; i< x;="" i++)="" readline="">

  Start reading the useful lines

  ReadLine () / / read a line

  ... / / Interpret the line

  Don't forget to add a control during i/o operations of robust error and to check the end of the file.

• How to get the value of DST?

  Hello

  Is there a shortcut to get the value of DST? For example, if the device is in London (for example), while I get back to London DST (+ 2, for example). And if the time zone is not DST, it returns 0 or null.

  I use it now

      int DST = TimeZone.getDefault().getOffset(1, rightnow.get(Calendar.YEAR), rightnow.get(Calendar.MONTH), rightnow.get(Calendar.DAY_OF_MONTH), rightnow.get(Calendar.DAY_OF_WEEK), rightnow.get(Calendar.MILLISECOND));
  

  It does not return the correct value. Thank you!
