Problem converting java.util.HashMap in an ActionScript object

• Basic question on java.util.HashMap

  Hello
  
  Say I want to store the number of copies of books like the value of a HashMap and use the key of the book object. Suppose that my book objects are very large.
  
  My question is this: will my HashMap object store the actual book or simply use the result of the hash function (called on my book of things) to 'put' a new book as well as the number of copies in the hash table?
  
  Here's how "to" the book in my card:
  

  myMap.put(firstBook, 8);
  myMap.put(secondBook, 2);
  etc...

  Thanks in advance for your help,

  No objects are copied (except if you explicitly copy) and no objects are stored in the map. (Indeed, no object is is never stored "inside" other objects in Java.) The hash table stores a reference to the key object and a reference to the value object. But also long your exsists in key-value pair in the leaf of the object key and the value object will be resident in memory and GC in United Nations.

• problem of java.util.Date

  Hi gurus,
  
  My requirement, that is to make a date validation, a process runs only between January 1 and 5, how can I retrieve the current year and place it in a two variables, so I can compare to the current day... I try to do this without success, when I ran the app shows me error, I am doing this with OFA, here is my code:
  
  OANLSServices service = pageContext.getOANLSServices ();
  SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/YYYY");
  Day dToday = new Date();
  String sToday = sdf.format (dToday);
  dToday = services.stringToDate (sToday);
  Date d1 = new Date();
  Date d2 = new Date();
  String s1 = sdf.format (d1);
  String s2 = (d2) sdf.format;
  D1 = services.stringToDate (s1);
  D2 = services.stringToDate (s2);
  D1. SetDate (1);
  D1.setMonth (1);
  D1.setYear (dToday.GetYear ());
  D2. SetDate (5);
  D2.setMonth (1);
  D2.setYear (dToday.GetYear ());
  If ((dToday.equals (d1) | dToday.after (d1)) & & (dToday.equals (d2): dToday.before (d2))) {}
  some instructions
  } else {}
  instructions of another
  }

  This seems to do the hard work of a simple problem. Why not just create a departure Date of 1 Jan 00:00 object, a last Date 5th Jan 23:59 object, then use Date methods to compare the Date of today with these two object?

  No you can use this code you don't use link layer

  remove this code. You will get the selected value in this string variable

  Just write this about you button action and verification.

• 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

• Access denied ("java.util.PropertyPermission" "user.timezone', 'writing') [WINDOWS 7 64 bit]

  Hello

  that we got on several computers, the error message

  
  

  access denied (java.util.PropertyPermission""user.timezone', 'write')

  When we try to open an internal Web site. Until today, that everything worked well.

  An update of Java for windows 7 64, Version 7 45 update does not resolve the problem.

  I tried to set the Java security permissions in the control panel to the Middle, but it also did not work after this change.

  We also got this problem on another computer when you try to open an external site that also use the Java.

  Someone has any idea how to solve this problem?

  Hi guys.

  I solved the problem by adding a rule to the following file

  $JAVA_HOME\lib\security\java.policy

  grant {}

  ...

  permission java.util.PropertyPermission "user.timezone", "write";

  };

  After that I killed the java process and rebooted. The problem disappeared

  That's pretty much what you should expect when you write code that has absolutely NO verification errors or parameter control at all.

  GIGO - Garbage In, Garbage Out.

  Your compression method uses an array of bytes for a parameter. This byte array can be any legal size.

  Then you HARD-CODE the size of the byte array target/tablet to 2 million bytes. You want to keep only the fingers crossed that the compressed size will fall into this buffer. And your method does not check for errors.

  What makes you think that an array of bytes in the entry that is 1 GB in size will compress in 2 million bytes?

  Then you make similar assumptions for the method to decompress; you ASSUME that the decompressed data size will be no more than three times the compressed size.

  int compressionFactorMaxLikely = 3;
  int bufferSizeInBytes = numberOfBytesToDecompress * compressionFactorMaxLikely;
  byte[] bytesDecompressed = new byte[bufferSizeInBytes];
  

  And you already know what's going to happen if your assumtions are wrong.

  If you want to learn how to write good code you can not make any assumptions as you do. If you make assumptions, you need to add code to validate that your assumptions are correct, check the length of the tables being passed and add the error handling so that you know when things are bad.

  The foregoing would be bad enough, but the biggest mistake you do is reinvent the wheel. You write custom code to implement features that Java already provides for you.

  The best solution to your problem is to simply create a zip file standard of your entry. ALWAYS, ALWAYS, ALWAYS start with the simplest solution that meets your needs.

  A solution of zip files:

  1. the uses out of the box functionality Java – you have to write code that interacts with the API classes
  2. you can read/write the files of any arbitrary size without having to allocate buffers of unknown size.
  3. has a very minimal overhead in the zip file for the central directory structure of input data that are necessary for a single file and zip.
  4 makes it easy to inspect the contents of the zip file, because the file can be opened with ANY zip utility.
  5. makes it easy test read and write functionality separately. Just use Winzip or another utility to create a zip of an example of BMP file and then test your code to see if you can decompress.
  6. you can only work with the flow of input/output instead of arrays of bytes.

  I suggest abandon you your current approach and implement a read/write zip utility that interfaces with your BMP files you need. Only if that is not your needs in the long run you must use a custom approach.

  There are many simple examples on the web that show how to create, read and write zip using Java files. And here are two:

• 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.

• java.util.concurrent.Executor.execute)

  Hi all
  
  The API for java.util.concurrent.Executor.execute () says:
  
  Executes the given command at some point in the future. The command can execute in a new thread, a thread from the pool or in the calling thread, at the discretion of the implementation of the executor.
  
  If the calling thread is the EDT and I need to process something on a thread split to release the EDT and it is processed (by the execute() method) on the calling thread, which is the EDT, there would be a problem. Is there a way to tell execute() does not treat on the calling Thread?

  No standard implementations run on the current thread. It is all explained in the javadocs, with "known application classes.

  Of this kind, I understand that my list object is not correctly stated on this point is the generic type. LinkedList generic type E, what is false. Can someone explain to me how do I correctly report LinkedList, or otherwise I do wrong. I'm not sure that understand this generic problem here.

  Collections.sort can only sort comparable objects (or use a separate comparison). You would need to have a Comparable upper limit for E.

  Since java.sql.Timestamp extended (i.e., "is a") java.util.Date, simply use the constructor Timestamp (java.sql.Timestamp):

  // y is a java.util.Date
  
  oracle.jbo.domain.TimestampLTZ x = new TimestampLTZ(y);
