  You can not convert the ArrayList to direct object value

  java.util.ArrayList selectedValues = (java.util.ArrayList) valueChangeEvent.getNewValue ();

  write like this-

  ArrayList selectedValues = new ArrayList();

  	Object [] str = (Object []) valueChangeEvent.getNewValue ();
  	for (int i = 0; i)< str.length;="" i++)="" {="">
  	System.out.println (STR [i]); selectedValues.add (str [i]); Add the values from an ArrayList

  I use my own enterprise Java API (they make to apache savings) in my blackberry project. but when I use these classes in my project, his error giving because they use arraylist map etc but here in my project its error, ID do not coz you know there is no card ArrayList etc classes in BB.

  There is no way you can use except re-implement all of your API, because Blackberry using JavaME and not JavaEE/SE. But the work will be too big to do.

• How killi thread and stop java.util.Timer?

  Hello
  
  I have table list, this list contains my objects (areas of Thread) and these threads use the Timer (java.util.Timer).
  
  In some time, I need to find the object in the list of tables, destroy this specific thread and immediately to stop the timer.
  
  I don't know what is the best way how a) destroy the thread and b) stop the timer.
  
  Could you tell me what technique to use?
  
  Thank you.

  I don't think you're catching what everyone tells you:

  Unless I missed something in your code, you do the following:

  1 create a thread that starts a timer (the thread itself dies immediately after the launch of the timer)
  2 put the dead (or soon to die) wire reference in a list of tables.

  To solve your problem, as has already been said: stop timers, they exist independently of your son now dead. Remove the reference ArrayList where you keep a list of the dead son. They will be eligible for garbage collection when you have no refrence to them any longer. Java garbare collector will not immediately work to show you got something, it is that way by their design, but ultimately it will collect your dead and not referenced objects and drop them.

  It's your original code, with a few lines more pronounced:
  ArrayList tempCommonWatchedMovies = new ArrayList();
          for (int i = 2; i < watchedMoviesSet.size(); i++) {
              ArrayList tempWatchedMovies = watchedMoviesSet.get(i);
              for (int movie : tempWatchedMovies) {
  ***            for (int commonMovie : commonMovies) {
                      if (movie == commonMovie) {
  @@@                    tempCommonWatchedMovies.add(movie);
                      }
                  }
              }
  ###         commonMovies = tempCommonWatchedMovies;
          }
  
  Although the version of your table might work, I'll explain the problem with your original version of ArrayList.
  The line I marked with # fact "commonMovies" have the same value as "tempCommonWatchedMovies". For i = 2, your loop will pass by without exceptions. At that time, ' commonMovies! = ' tempCommonWatchedMovies and therefore him 'Add' on the line with @ has no bearing on the same list. However, for I = 3, 'commonMovies' points to the same list as "tempCommonWatchedMovies" (that is, "commonMovies == tempCommonWatchedMovies' set to true). Then when you are iterating "commonMovies" online *, you are iterating over the same list to which you add items to the line. So, the ConcurrentModificationException occurs. According to what is originally watchedMoviesSet, the error may occur not on i = 3. The error occurs for the first 'i' for which the line @ is called.
  For I > = 3, your loop where the error occurs is actually:
  ***            for (int commonMovie : tempCommonWatchedMovies) {
                      if (movie == commonMovie) {
  @@@                    tempCommonWatchedMovies.add(movie);
                      }
                  }
  
  or equivalently,
  ***            for (int commonMovie : commonMovies) {
                      if (movie == commonMovie) {
  @@@                    commonMovies.add(movie);
                      }
                  }
  
  When writing in this way, it may be more obvious as to why the ConcurrentModificationException happens - you are iterating over the list to which you add items.
  Instead of line #, you can try this:
  commonMovies = new ArrayList(tempCommonWatchedMovies);
  
  Then you hold the same values in both lists, but the lists themselves are different, and the ConcurrentModificationException will not happen.
  You can also try to look of the ArrayList retainAll method. You'll probably want to make copies of the list (as in my example of code) to avoid damaging the original lists (if you need the originals to be still intact). But, retainAll should allow you easy ways to keep only the common elements. Underneath, retainAll will always make the loops that you do, but your code will be shorter, because the curls will no longer appear in your own code. You will have just a few copies and a few calls to retainAll.
  		   

• Foglight v558 - Script fails with ScriptAbortException: script1001968: java.util.ConcurrentModificationException

  I have changed most of our rules through several Wssf and use a number of rule-level Variables. I got these variables through groovy scripts.

  Recently, I had to change a variable that appears in all the rules.

  This is the script that I have written so far:

  com.quest.nitro.service.sl.interfaces.rule import. *;

  def ruleInfo = "";
  def ruleSvc = server.get ("RuleService");
  def ruleList = ["DBSS - ADH Service status"];
  def varExp = "INST_NAME;
  def varText = "scope.parent_node.mon_instance_name";

  allRules = ruleSvc.getAllRules ();

  for (rule allRules) {}
  ruleName def = rule.getName ();
  def ruleCart = rule.getCartridgeName ();

  If (ruleList.contains (ruleName))
  If (ruleCart.equals ("DB_SQL_Server_UI")) {}
  def ExpressionSet = rule.getExpressions ();
  for (expression in ExpressionSet) {}
  If (expression.getName () .equals ("INST_NAME")) {}
  ExpressionSet.remove (expression);
  ruleInfo += "Removed variable $varExp of $ruleName \n";
  }

  }
  Add a new term
  ExpressionSet.add (rule.createExpression ("INST_NAME", varText));

  rule.setExpressions (ExpressionSet);
  ruleSvc.saveRule (rule);
  ruleInfo += "added $varExp variable $ruleName \n";
  }
  }

  Return ruleInfo;

  The part of the script that adds the variable work consistantly.  The part of the script removes it expresion of level rule fails most of the time with the following error:

  com.quest.nitro.service.sl.interfaces.scripting.ScriptAbortException: script1001968: java.util.ConcurrentModificationException

  I'm still fairly new to groovy and java script, but I gather that when I have to iterate over a collection that is changed in another thread, the iterator survey a java.util.ConcurrentModificationException.  I read that I should look somehow collection synchronization.  Before we go down this rabbit hole, I thought I would just ask here, how should I write this code then it work consistantly?

  This is due to brakes on an object. You can try to break your code into pieces. First of all try and get all the rules in a list that matches your criteria. Call it a refinedRuleList, and then iterate through this refinedRuleList for Expressions and remove them. This gives a try!

  Thank you

• move on java.util.Map parameter to Servlet

  Hello

  I use jdeveloper 11.1.1.3.0

  I have set a java.util.Map as pageFlowScope parameter setting and fill in a bean:

  java.util.Map paramMap = new HashMap();
  paramMap.put("key1","value1");
  .
  .
  .
  Map<String, Object> pageflowScope =
  AdfFacesContext.getCurrentInstance().getPageFlowScope();
  pageflowScope.put("formParam", new HashMap());
  pageflowScope.put("formParam", paramMap);
  
  
  
  
  

  so, I want to send this parameter to servlet by a goLink as follows:

  <af:goLink text="goLink 1" id="gl1"
           destination="/render_image? param=#{pageFlowScope.formParam}"
     targetFrame="_blank"/>
  
  
  
  
  

  but in the servlet when I wanted to get this parameter the exception below occurs

  Map paramMap = (Map)request.getParameter("param");
  
  

  Error 500 - Internal server error

  java.lang.ClassCastException: java.lang.String cannot be cast java.util.Map

  How can I pass a parameter java.util.Map to servlet?

  Habib

  And that returns a String is a

  #{pageFlowScope.formParam}

  I guess?

  As a final attempt by me:

  1. before redirecting to servlet (by af:goLink), put your hashMap not the pageFlowScope, but the sessionScope attribute, say "formParam.

  2. in the redirect (when specifying the destination for the goLink), don't specify any parameter (jump? param =... part)

  3. in the servlet, try again with the code I gave you already:

  public void doGet (HttpServletRequest request,

  HttpServletResponse response) throws ServletException,.

  IOException {}

  HashMap param (HashMap) = request.getSession () .getAttribute ("formParam");

  }

  If this does not work, then I don't have the answer

  import java.sql.SQLException;

  to import java.text.ParseException;

  import impossible;

  import java.util.Calendar;

  Import oracle.jbo.domain.Date;

  Import oracle.jbo.domain.Timestamp;

  Here is the method:

  public static Date (String sDate, int day, nextDay

  SimpleDateFormat String) {}

  Date result = null;

  java.util.Date date;

  If (sDate! = null) {}

  try {}

  System.out.println ("Try...");

  Calendar calendar = Calendar.GetInstance ();

  SimpleDateFormat dateFormat =

  new SimpleDateFormat (simpleDateFormat);

  calendar.setTime (dateFormat.parse (sDate));

  Calendar.Set (Calendar.DAY_OF_WEEK, date); day = Calendar.SUNDAY

  Calendar.Set (Calendar.HOUR_OF_DAY, 0);

  Calendar.Set (Calendar.MINUTE, 0);

  Calendar.Set (Calendar.SECOND, 0);

  Calendar.Add (Calendar.DATE, 7);

  dateFormat.format (calendar.getTime ());

  try {}

  System.out.println ("try (inside)... ») ;

  "System.out.println (" new Timestamp (calendar.getTime () .getTime ()) "):" +.

  new Timestamp (calendar.getTime () .getTime ()));

  result = new Date (Timestamp (calendar.getTime () .getTime ())) new; Code does not work here.

  return the result;

  } catch (SQLException e) {}

  System.out.println ("catch (SQLException e)... ») ;

  e.printStackTrace ();

  }

  Returns a null value.

  } catch (ParseException exception) e {}

  System.out.println ("catch exception e ParseException... ») ;

  e.printStackTrace ();

  }

  Returns a null value.

  }

  Returns a null value.

  }

  Here is the result:

  try...

  Try (inside)...

  new Timestamp (calendar.getTime () .getTime ())): 2013-12-29 00:00:00.0

  catch (SQLException e)...

  java.sql.SQLException: failed initialization

  to oracle.sql.DATE. < init > (DATE.java:237)

  to oracle.jbo.domain.Date. < init > (Date.java:378)

  try to convert timestamp to jbo.date as

  java.sql.Timestamp datetime =newjava.sql.Timestamp(System.currentTimeMillis());

  oracle.jbo.domain.Date daTime =new  oracle.jbo.domain.Date(datetime);
