• We can access the session scope variable just by using its name

  Java EE 6 tutorial contains a "Case Study of the Duke's Bookstore example". I did not understand after statements of this case study:
  
  * bookdetails. XHTML *.
  
  {code}
  < h:outputText value = "#{selected.title}" / >
  {code}
  
  * BookstoreBean.Java*
  
  {code}
  public String details() {}
  Context()
  . getExternalContext()
  . getSessionMap()
  .put)
  "selected."
  getFeatured());
  
  return ('bookdetails");
  }
  {code}
  
  I want to know we can access the defined in bookdetails.xhtml session variable by simply using his name as done previously?

  This is a feature of basic Expression Language (EL), it is not specific to JSF. And it is not specific to the scope of the session, or you can put the beans in any area (page, request, session, application, flash, conversation, regardless of how extensive custom that you create) and reference it using EL only his name. The thing you need to take care of, is that the bean lives in a scope, which can be done using JSF specific or files of configuration, through CDI, annotations or by manually setting the bean in a specific through Java code scope. It is flexible, that is the nature of the Java platform.

• How to get the static attribute by using its name as a string

  I have an app with about 100 boxes of single drop-down list (this is a requirement of the Government, I'm not that bad a designer) and I would like to define the choices in a single file separated like this:

  package components {}

  Import mx.collections.ArrayCollection;

  public class {choice}

  [Bindable] public static var A0310A: collection ArrayCollection = new ArrayCollection ([] collection
  {value: '01', label: 'Admission'},
  {value: "02", label: "Quarterly"},
  .. .snip...
  ([{value: "99", label: "NOT the OBRA required"}]) ;
  
  public static void getChoices(name:String):ArrayCollection {}
  var temp: ArrayCollection = collection?
  Return temp;
  }
  
  }//----------------end of class--------------------------------
  }//======================== end of package==============================

  I want to use it like this

  < my: ComboBox id = "mdscombo" tag = "A0310A" / >

  Where the definition of my: ComboBox includes the code like this

  var zz:ArrayCollection = Choices.getChoices (name);

  but I can not find any function that will allow me to do.  I don't want really clutter up the code by creating a name-> object mapping table.

  I had also considered using the XML data type, but I have the same question, unless I had all the choices under a single root (possible), but this could be a nightmare when debugging in typo XML file.

  Any suggestions?

  To answer your question, you can access static variables with a chain in this way:

  Choice ["A0310A"]

  However, you probably want to re-evaluate your design because this isn't a very desirable approach.

• How to find a table, using the name of the column in the database schema

  Dear all,
  
  Please help me on
  
  using the name of the column, how to find a table name in the database schema.
  
  Thanks in advance

  Hello

  You can query the data dictionary views all_tab_columns and user_tab_columns.
  For example, to find the tables in the scott schema have called deptno columns:

  SELECT  table_name
  FROM    all_tab_columns
  WHERE   owner           = 'SCOTT'
  AND     column_name     = 'DEPTNO';
  

  Remember that anything inside quotes is case-sensitive.

  The all_tab_columns view has one row for each column in each table (or view) that you have the privileges to use.
  The user_tab_columns view is a subset of all_tab_columns, containing only your own tables (and views).

• How is group a cluster by its name?

  I created a group of 2 calculated values (x = r * cos (angle) and y = r * sin (angle) where are and angle are given by sensors (the angle is converted to radians).)  The documentation says "right click on the cluster and enter the names (presumably, x and y in my example.).  I followed the instructions, but no window open to allow me to provide the names.  What I am doing wrong?

• help Windows cannot access the specified device, path or file. You can not have the appropriate permissions to access the item.

  I downloaded a game and I'm going to open and it says Windows cannot access the specified device, path or file. You can not have the appropriate permissions to access the item.

  The thing is I had this game on this laptop before and worked fine.

  But every time that there is a update for the game, you have to uninstall it and then reinstall it.

  When I reinstalled it.

  I now get Windows cannot access the specified device, path or file. You can not have the appropriate permissions to access the item.

  It's windows 8, I am using.

  What is the problem?

  Hello

  Thanks for the reply.

  You can try to temporarily disable the antivirus program and check the results. It can also occur if you have not enough permission to run the file.

  Caution:
  

  Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

• How can I get Mozilla to use the name of the page for the name of the real instead of the URL bookmark when I bookmark a page

  I just noticed that (in comparison to Internet Explorer): in IE, when you preferred a Web page, it uses the actual name of the Web page (for example, for this page, it would be "Ask a Question Firefox Help" as the name of the bookmark), but in Mozilla, it uses the URL as the name of the bookmark. I was wondering if it was possible to change my Mozilla settings so that it uses the name of the Web page as the bookmark name instead of the URL? I hope that everyone understands what I am getting? If anyone can help me, I would really appreciate it. Thank you.

  Firefox uses the tag title for the name of the newly saved bookmark.

  When I bookmark on this forum page I get this for the 'name' of the bookmark.

• Use: How to read a single line of names of channel or units?

  Most of the examples of programming to use use channel names in separate lines, as in the following example:

  Channel
  Name: time
  Type: time

  Channel
  Name: XShift
  Type: R64

  Channel
  Name: YShift
  Type: R64

  Most of my data sets have channel names and / or units in one line separated by tabs as

  "Dehnung" "Standardkraft" "Sensor" "Zyklusnummer" "PWM".

  « mm » "N" "V" « » « % »

  Is there a more effective way to add channels appointed and equipped with units along these lines to bike through some index variable? Like my channel number, etc. naming vary frequently, I would be looking for a more flexible solution, avoiding fixed table or names hardcoded sizes.

  I guess

  aMyChannelNames = split (File.GetNextStringValue (eString), vbTab)

  aMyChannelUnits = split (File.GetNextStringValue (eString), vbTab)

  for i = 0 to UBound (aMyChannelNames)

  Adjust the strings = Block.Channels.Add (aMyChannelNames (i), eString)

  Channel.Porperties ("Unit") = aMyChannelUnits (i)

  next

  could do the job - but it's the most effective way?

  Thank you for helping.

  Michael

  Hello Michael,

  I don't see the real problem.

  You read the header and split it into an array. This is information you have how many channels. Table size ubound depends on the line you have red and is not fix. Everything should be good now.

  You read the information and would divide the tables. Then, you use a loop to generate channels and set the properties. I don't think that there is a better way to do it.
