• 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!

• Cannot convert abcd of the type class java.lang.String interface java.util.List

  Hello

  }

  public String getLstboxcatg() {}

  Return lstboxcatg;

  }

  can I get a nullpointerexception on line object str = listBindings.getSelectedValue ();

  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.

  System.out.println (selectedVal);

  You can not convert the ArrayList to direct object value

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

  write like this-

• 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:

• ClassCastException: java.util.ArrayList cannot be cast to oracle.adf.view.f

  Hello
  
  I am currently check why I encounter this error in a line graph?
  
  Basically I have the managed bean

  public class TestMB
  {
    private List<Object[]> tabularData = new ArrayList<Object[]>();
  
    public void setTabularData(List<Object[]> tabularData)
    {
      this.tabularData = tabularData;
    }
  
    public List<Object[]> getTabularData()
    {
      
      return tabularData;
    }
  }

  In the code, I have this defined graphic line.

  <dvt:lineGraph id="lineGraph1" subType="LINE_VERT_ABS"
     emptyText="No Data To Display"
     value="#{backingBeanScope.TestMB.tabularData}"
     contentDelivery="immediate">
         <dvt:background>
            <dvt:specialEffects/>
         </dvt:background>
         <dvt:graphPlotArea/>
         <dvt:seriesSet>
            <dvt:series/>
         </dvt:seriesSet>
         <dvt:o1Axis/>
         <dvt:y1Axis/>
         <dvt:legendArea automaticPlacement="AP_NEVER"/>
  </dvt:lineGraph>

  But I continued to encounter this error.
  

  java.lang.ClassCastException: java.util.ArrayList cannot be cast to oracle.adf.view.faces.bi.model.DataModel

  My thought is that I would be able to display the emptytext attribute.

  Neliel,

  You must link to the tabularData property and not to the value property.

• 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.

• Where are the java.util.logging properties?

  Hello
  
  We have a java code that is called from PL/SQL. The Java code uses java.util.logging to connect diagnostic and error messages.
  
  Where are the papers?
  
  Where we can configure logging properties?
  
  DB is Oracle 11 g.
  
  Documentation (Guide of the Java developer, 11 g Release 2 (11.2), E10588-04) says nothing about the record.
  
  Thank you...

  Hi, Roger:
  The recorded information come to the .trc file for the Oracle (shared or dedicated) server process.
  .trc files are the Oracle Diagnostics directory, for example:
  $ORACLE_BASE/diag/rdbms / $ORACLE_SID / $ORACLE_SID/trace
  To configure log file properties read this blog entry:
