• "" Type = "java.math.BigDecimal type =" Oracle.jbo.domain.Number "VS".

  Hi all! I need some explanation about types: Type = "oracle.jbo.domain.Number"VS Type = "java.math.BigDecimal"
  
  I have variable enableEditing:
  

   this.enableEditing = this.getSelectedTaks().getAttribute("TaksacijasPk").equals(taksId); 

  If attribute EO TaksacijasPk is with the type "oracle.jbo.domain.Number" then all work with above the line, but if this attribute is of type "Java.Math.BigDecimal" then code above line do not work. To fix it, I need to add toString() operation in the line of code:
  

   this.enableEditing = this.getSelectedTaks().getAttribute("TaksacijasPk").toString().equals(taksId); 

  Maybe the question is, why in one case, I have to add toString() operation and in others not?
  
  Best regards, Debuger!

  Javadoc for the BigDecimal said

  Unlike compareTo, this method takes two objects BigDecimal equal only if they are equal in value and scale (so 2.0 is not equal to 2.00 compared to this method).

  You try to compare a BigDecimal/number for a taskId (which we don't have no idea what class it is).

  Suppose that taskId is a string.

  . Equals() on a number will simply convert the string to a number and check if the values are equal.

  . Equals() on a BigDecimal allows you to convert the string to a BigDecimal by applying the rules described in the BigDecimal (String) constructor, to-wit:

  The scale of the BigDecimal returned will be the number of digits in the fraction, or zero if the string contains no comma, subject to adjustment for any Exhibitor; If the string contains an exponent, the exponent is subtracted from the scale. The value of the scale that results must be between Integer.MIN_VALUE and Integer.MAX_VALUE, inclusively.

  My conjecture only (since you don't seem to be ready to use the debugger and check), is that you have a scale on your BigDecimal which does not match the scale on the BigDecimal which is built from the identifier.

  If I had to try to understand the difference between the two, I'd read the docs. Maybe even create a few test cases. Maybe to run my code in the debugger to see what that my BigDecimals and numbers looked like

• In general, is it better to use java.sql.Date and java.sql.Timestamp instead of oracle.jbo.domain.Date?

  Hello world

  During playback of Oracle ADF Real World Developer's Guide, I noticed the dates match occurring in JDeveloper is different from what is the list in the book. JDeveloper is failing to oracle.jbo.domain.Date, but according to the book:

  DATE	java.sql.Date	DATE type is mapped to java.sql.Date if the column in the table is a no time didn't need information zone.
  DATE	java.sql.Timestamp	DATE type is mapped to java.sql.Timestamp if the column in the table has a component "time" and that the client needs to zone information.
  TIMESTAMP	java.sql.Timestamp	The TIMESTAMP type is mapped to java.sql.Timestamp if nanosecond precision is used in the database.

  In general, is it better to use java.sql.Date and java.sql.Timestamp instead of oracle.jbo.domain.Date? Using java.sql.Date and java.sql.Timestamp could save me some headaches conversion date. And, is there a place in JDeveloper to display these maps? I looked around and didn't see anything.

  Thank you.

  James

  User, what version of jdev we are talking about?

  In GR 11, 1 material versions db types date and timestamp are mapped to types of domain data that represents a wrapper for the native data types. The reason was that the framework can work with the domain types regardless of the underlying data type.

  Since Oracle 11 GR 2 maps the types DB to java types (default selection, you can change it when you create a model project, you can set the Data Type Mapping). Once the pilot has business components define you cannot change this setting it would break existing components such as eo or vo.

  So if you are working wit 11 GR 1 subject, you must use the domain types, if you work with GR 11, 2 or 12 c, you can use the domain types, but it is recommended to use the java type mapping.

• Installation of Oracle SQL Developer and Java

  I finished installing the Oracle Client without problems. SQL Developer opened for the first time and he asks me the full path Java.exe.
  
  That's fine, but when I entered the java.exe I just don't ask again, no errors. Repeat to infinity.
  
  I have the most recent Java SDK installed and tried the 32-bit and 64-bit versions (jdk 7u4). I even tried to install Oracle Client version 11.1.0 AND 11.2.0 to see if that makes a difference, but it is all the same.
  
  I uploaded a screenshot if that helps: http://i50.tinypic.com/mjtqte.jpg
  
  Any ideas?
  
  Kind regards

  Hi Gunnar.

  Documentation:
  http://docs.Oracle.com/CD/E25259_01/doc.31/e26419/install.htm#sthref8

  Ideas:

  -Do not use java7
  -Use JDK JRE not
  -On widows, there is a version of SQLDeveloper, including jdk 6 java
  -Instant client is not necessary - but if you want to use use at least 11.2.0.2
  -SetJavaHome updated to sqldeveloper\sqldeveloper\bin\sqldeveloper.conf to point to the JDK
  -There is some confusion about 32-bit and 64-bit operating systems, java and SQLDeveloper, you can search the forum for more details, for example: put on the title: "Unable to start Oracle SQL Developer.

  CREATE OR REPLACE FUNCTION F_SECONDMAX_J (NUMBER value) RETURN NUMBER

  AGGREGATION to the HELP of SecondMax_j;
  /
  
  
  
  When I now use the F_SECONDMAX_J function.
  
  "(Columnname) select F_SECONDMAX_J from Tablename t;
  
  It works perfectly and shows me the right result.
  
  Then I tried to implement the fusion part as follows:
  
  public BigDecimal ODCIAggregateMerge (oracle.sql.STRUCT ctx2) throws SQLException {}
  
  BigDecimal Key2 = null;
  
  BigDecimal ctx_max = null;
  BigDecimal ctx_secmax = null;
  
  BigDecimal ctx2_max = null;
  BigDecimal ctx2_secmax = null;
  
  retrieve the context stored with the key
  StoredCtx_SecMax ctx = null;
  try {}
  CTX = (StoredCtx_SecMax) ContextManager.GetContext (Key.intValue ());
  } catch (Exception e) {}
  
  }
  
  Object [] impAttr = ctx2.getAttributes ();
  
  Key2 = (BigDecimal) impAttr [0];
  
  retrieve the second context stored using the key2
  StoredCtx_SecMax ctx_sec = null;
  try {}
  ctx_sec = (StoredCtx_SecMax) ContextManager.GetContext (key2.intValue ());
  } catch (Exception e) {}
  
  }
  
  ctx_max = ctx. LeseMax();
  ctx_secmax = ctx. LeseSecMax();
  
  ctx2_max = ctx_sec. LeseMax();
  ctx2_secmax = ctx_sec. LeseSecMax();
  
  If (ctx2_max.compareTo (ctx_max) == 1)
  {
  If (ctx2_secmax.compareTo (ctx_secmax) == 1)
  {
  CTX. SchreibeSecMax (ctx2_secmax);
  }
  on the other
  {
  CTX. SchreibeSecMax (ctx_max);
  }
  CTX. SchreibeMax (ctx2_max);
  }
  on the other
  {
  If (ctx2_max.compareTo (ctx_secmax) == 1)
  {
  CTX. SchreibeSecMax (ctx2_max);
  }
  }
  
  return a SUCCESS;
  }
  
  When I now try the function
  
  "Select / * + parallel (t 4) * / F_SECONDMAX_J (Columnname) of Tablename t;
  
  I always get a pointer NULL-error because the variable key2 is always 0 and therefore the functions LeseMax() and LeseSecMax()
  in the second context 'ctx_sec' produce this error NULL pointer.
  
  To me it seems that each parallel process is the construction of an additional class for himself, which is not available are my main process.
  
  My question is now how it is possible to access the context of stored of the parallel process, so that I can combine the results.
  
  Thank you very much

  Hi Josef,

  just guess that I've never implemented with java user-defined aggregate functions or support parallel execution:

  Maybe you have to implement ODCIAggregateWrapContext?

  + Application of ODCIAggregateWrapContext is optional. It should be implemented only when the external memory is used to hold the aggregative, context and the user-defined aggregate is evaluated in parallel (which is, stated as PARALLEL_ENABLE). If the user-defined aggregate is not evaluated in parallel, ODCIAggregateWrapContext is not necessary. +
  [http://docs.oracle.com/cd/B12037_01/appdev.101/b10800/dciaggfns.htm#i1004974]

  Report it to progress and success.

  Good luck

  At run time, when searching on an attribute in the nested criteria (ViewObj2), I get: ORA-00904: "QRSLTSQ1." "' VO1_ID ': invalid identifier.

  The query that is executed is:

  SELECT *
  FROM
    (SELECT 1 VO1_ID,
      'ViewObj1' TITLE
    FROM DUAL
    ) QRSLT
  WHERE ( ( (EXISTS
    (SELECT *
    FROM
      (SELECT 1 VO1_id, 2 VO2_ID, 'ViewObj2' TITLE FROM DUAL
      ) QRSLTSQ2
    WHERE ( (VO1_ID      = :vc_temp_1 ) )
    AND (QRSLTSQ1.VO1_ID = QRSLTSQ2.VO1_ID)
    )) ) )
  
  
  

  As you can see on line 13, it's with the help of QRSLTSQ1. VO1_ID when he is recommended to use QRSLT. VO1_ID.

  I'm doing something wrong? If not, is there a fix or a workaround for this bug?

  Thank you

  Bill

  It seams to be a strange behavior in the 12.1.3 sql builder. In this post VC Jdeveloper application encapsulating a user has reported something similar. He found a work around (last post of the thread) that you can try.

  Anyway, if thre is a fix available for what you ha vet oask support.oracle.com (paid support contract). They are the only ones who can tell you if it's a bug, after all, and if a fix is available. If this isn't the case, you can request a.

  For any help, I'll be very grateful

  Concerning

  Tender,

  As I mentioned in the other thread, the var0 comes null which causes this problem.

  Why var0 just null?

  You must change the property of destination as below:

  You must add "="

  See you soon

• Problem of composite key chain BigDecimal, pair

  JDeveloper 12.1.3

  I have OS based on a table that has the following PK

  Task_Id NUMBER

  Id_ressource Varchar2 (6)

  Using the EO above, I have a VO to view data in the user interface. I get the problem in the bean to support (test code below)

              DCBindingContainer dcbindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
              DCIteratorBinding iterator = dcbindings.findIteratorBinding("TaskCalendarIterator");
              System.out.println(activity.getProvider().getId());
              //Key key = new Key(new Object[] { activity.getId(),activity.getProvider().getId() });
              java.math.BigDecimal key1= new BigDecimal(140080);
              String key2="ds1";
              Key key = new Key(new Object[] { key1,key2 });
              System.out.println(activity.getId());
              System.out.println(key);
              RowSetIterator rsi = iterator.getRowSetIterator();
              Row row = rsi.findByKey(key, 1)[0]; //!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here is where exception is thrown
              rsi.setCurrentRow(row);
  

  Caused by: oracle.jbo.domain.DataCreationException: Houston-25009: failed to create an object of type: java.math.BigDecimal type: java.lang.String with value: ds1

  Recording with the key 140080, ds1 exists in the iterator.

  I thought that the key can be anything, including channels?

  OK, I got the problem solved. The order of the key attributes must be identical to the order of these attributes in the original Version, NOT in OT

  The order was therefore, in my case in OT, TaskId, ResourceId

  Vo to ResourceId, TaskId

  That's why in the bean to support code, it must be:

  java.math.BigDecimal key1= new BigDecimal(140080);  //This is TaskId
  String key2="ds1";  //This is ResourceId
  Key key = new Key(new Object[] { key2,key1 });

  I am trying to create a new rule. I want to compare a value to a threshold, which comes from a variable.

  I'm stuck with this issue:

  Can't compare com.quest.nitro.model.canonical.bean.SingleValueMetricSummary with the value "97.0 ' and Java.Math.BigDecimal with the value «95.0 '»»

  https://support.quest.com/SolutionDetail.aspx?ID=SOL90787 is not useful:

  With the help of getAvg() results in java.lang.NullPointerException.

  That's how I get my values:

  Val = ds.retrieveLatestValue(scope,_it).value

  Any ideas?

  This should work:

  Val = ds.retrieveLatestValue (datastore, "totalSpace")? value?. AVG

  Just a thought, however, is that retrieveLatestValue is not a good idea for a rule, because they should work on current values.

  retrieveLatestValue displays the last value collected, that would have made last week.

  Val = #totalSpace # would be more appropriate for a rule whose scope is VMWDatastore.

  Of course, would be replaced by metric topology to the scope name.

• java load problem

  I have the following code segment of asktom.com that it can compile if I run it in the form of sql script, but when I compile and package the code in Eclipse and load it into db by sqldeveloper I get the following error

  java.sql.SQLException: ORA-29509: incorrect binary definition of class Java

  any help will be really appreciate it.

• BigDecimal rounded - no arrivez.5 round 1

  Why can't I pas.5 to round to 1 using BigDecimal.
  
  Here's the code;
  
  java.math.MathContext mc = new java.math.MathContext (1, java.math.RoundingMode.HALF_UP);
  
  Java.Math.BigDecimal obj_0 = new Java.Math.BigDecimal ("0.5");
  System.out.println ("value of obj_0:" + obj_0);
  System.out.println ("result generated method:" + obj_0.round (mc));
  
  Here is the result;
  obj_0 value: 0.5
  result of the generated method: 0.5
  
  This works as expected for greater than 1 decimals.
  
  What Miss me about BigDecimal mathematically?
  
  Thank you.

  >
  If you can use BigDecimal rounding to the nearest whole number (one or zero) when the value is less than 1 and greater than zero?
  >
  Just set the scale and the rounding mode when you use the value.

  System.out.println("method generated result : " + obj_0.setScale(0, java.math.RoundingMode.HALF_UP));
  
  method generated result : 1
  

• ADF business components Type map Oracls vs Java

  What advantages and disadvantages of each one card
  
  I thank in advance

  Take a look at this link in the developer's guide:
  http://docs.Oracle.com/CD/E16162_01/Web.1112/e16182/bcintro.htm#sm0062

  The scope of Java to map Oracle and Oracle areas type plan manage numeric data differently. When you create a new application of the type mapping default Java extended for Oracle maps the digital data to the Java.Math.BigDecimal > class that inherits from java.math.Number. The default value of Java.Math.BigDecimal corresponds to the way that web view Fusion application layer, consisting of elements ADF Faces, retains the alignment of digital data (such as numeric values > posted by ADF Faces of fields on a web page). Whereas the areas of the Oracle type that maps digital data from the oracle.jbo.domain.Number class, may not display the data with alignment scheduled by some ADF Faces > components. Apart from this alignment problem, the plan of type Oracle areas remains a valid choice and applications without ADF Faces components will work without problem.

  Thank you
