• ProcessEntry (...) consistency: unknown user type: java.lang.Object

  Hello!
  
  I created a new class that extends the VersionedPutAll class. When I replace processEntry (...) method I get an exception:

  Exception in thread "main" (Wrapped: Failed request execution for DistributedCache service on Member(Id=1, Timestamp=2012-08-09 18:02:13.598, Address=192.168.1.1:8088, MachineId=49553, 
  Location=site:,machine:StBook,process:18387, Role=IntellijRtExecutionAppMain) (Wrapped) unknown user type: java.lang.Object) java.io.IOException: unknown user type: java.lang.Object

  The original VersionedPutAll works well. My class without processEntry (...) works well also. But the simple substitution of processEntry (...) as
  

  protected Object processEntry(InvocableMap.Entry entry, Map mapAll, boolean fInsert, boolean fReturn) {
      return new Object();
  }

  throws an exception.
  
  Does anyone know what is the problem? Thank you.
  
  

  public class ExtVersionedPutAll extends VersionedPutAll {
      private static final Object NO_RESULT = new Object();
  
      public ExtVersionedPutAll() {}

  The problem is that you try to return an instance of the EntryProcessor NO_RESULT and No_Result is of type Object. Coherence cannot serialize an ordinary object, so you get this error. You need to do something No_RESULT that can be serialized - object to primitive type or a custom class that is serializable POF.

• operation not allowed on java.lang.object

  Hello.
  
  I use jdeveloper 11.1.1.5
  
  I had used this code in my AMImpl method
  

         ViewObjectImpl vo = this.getFinPeriodsView1();
         Row vor= vo.getCurrentRow();        
         System.out.println("Current date : " + (vor.getAttribute("FpFromDate") + 1)  //getting error as operation not allowed on java.lang.object
         + "-"
         + now.get(Calendar.DATE)
         + "-"
         + now.get(Calendar.YEAR));
    

  My scenario is to perform this operation
  

  select max(add_months(fp_from_date,1)) from fin_periods  //This value is to be set to FPFromDate Attribute for FinPeriods

  select max(add_months(fp_end_date,1)) from fin_periods //This value is set to be set to FpEndDate Attribute for FinPeriods

  I need to do this for 12 periods that example sample is
  

  for (int i=0;i<=12;i++)
  {
    select max(add_months(fp_from_date,1)) from fin_periods;
    select max(add_months(fp_end_date,1)) from fin_periods;
  }

  How can I do this in my method of AMIMpl.

  Hello
  First add after the stuff inside your implementation code

  //Code Stuff in your mathod as follows
        Calendar cl = Calendar.getInstance();
        java.util.Date dateFromTable = convertDomainDateToUtilDate((oracle.jbo.domain.Date)vor.getAttribute("FyStartDate"));//check now
        cl.setTime(dateFromTable);
        System.out.println (cl.getTime());
        cl.add(Calendar.DATE, 30);//add 30 days
        Date toDate = cl.getTime();
        System.out.println (toDate);
  //
  

  and also add convertDomainDateToUtilDate new method to your class. Method will return java.util.Date to your oracle.jbo.domain.Date

  public java.util.Date convertDomainDateToUtilDate(oracle.jbo.domain.Date domainDate) {
   java.util.Date date = null;
   if (domainDate != null) {
   java.sql.Date sqldate = domainDate.dateValue();
   date = new Date(sqldate.getTime());
   }
  return date;
  }
  

• Cannot convert oracle.jbo.domain.DBSequence to class java.lang.Integer

  Hello

  I have the following problem with my ADF application developed in JDeveloper 12.1.3:

  In my model, there are two entities MeterEO and MeterTypeEO with the following attributes:

  MeterEO

  TenantId	BigDecimal	TENANT_ID	NUMBER
  MeterCode	String	METER_CODE	VARCHAR2 (48)
  Type	Integer	TYPE	NUMBER

  MeterTypeEO

  ID	DBSequence	ID	NUMBER
  Name of the vendor	String	NAME OF THE VENDOR	VARCHAR2 (32)
  Type	String	TYPE	VARCHAR2 (16)

  Type of MeterEO reference Id in MeterTypeEO.

  Appropriate VO of the meter uses a MeterTypeVO LOV to create a list containing the provider and Type as well as the user's selection.

  In the ModelTester, everything works well when I try to change a counter, select a new type and validate my changes to the database.

  A JSFF, it looks quite different. Selection is made by SelectOneChoice with the LOV list containing the provider and Type. Of the LOV the appropriate values are selected for the (integer) to the meter, then the user gets a readable text instead a few cryptic. But when I change the value by selecting a new choice I always got the error ' Can' oracle.jbo.domain.DBSequence to class java.lang.Integer.

  Why it works without problems in the Modeltester but not on the page?

  

  Please see the attached screenshots to make it clearer what I mean.

  Any hint is appreciated,

  Björn

  I solved my problem now in view objects. Maybe someone who has the same problem and is interested in the solution:

  In MeterTypeVO - which is the source for the LOV - I added a new transitional field called IntId of type Integer that refers to the field Id of type DbSequence by Expression. DbSequence is automatically converted at length which can be also automatically converted in full.

  At the counter, I changed the key of the LOV to IntId instead of code.

  It works like charm.

  VCloud Director version is 5.5 and the CentOS operating system.
  

  I hope someone can help.

  Solved the problem by directly inserting the values into the database of the vcloud Director.

  We found values in 'dbo.config' and change the 'value' for

  'consoleproxy.external.address '.

  "restapi.baseUri" and

  'system.external.link '.

  In our case there no had no entry for this three values so we created the entries.

  Now everything works fine.

  Thank you.

  Hi Rudy,.

  I guess that you have spotted it right. Instead of 5 in your disabled property, use '5'

  
  

  I mean, just surround it with quotes like below
  

  
  

  disabled="#{bindings.PGSchedType.inputValue ne '5'}"

  OK guys, we found the solution. We had to update the files of PVE strategy on our SOA server Linux machine.

  Thanks to Varun Guruvugari (Support Salesforce) who responded with below the answer on another forum:

  --===========================
  There are countless reasons for uninitialized encryption error, but I'm sure that this reason is because of SSL certificates and you saw the error above for good reasons that salesforce.com ensures the safety and security.

  You will be able to integrate successfully in this instance, by deploying the latest version of the files of Extension JCE (Java Cryptography) unlimited strength jurisdiction policy-6 for JDK1.6 on the server SOA in FMW. Here is a good article to allow strong encryption algorithms FMW:http://docs.oracle.com/cd/E19644-01/817-5447/sgencryp.html#wp15647

  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);

  The Java Exception: java.lang.reflect.InvocationTargetException: during the java.lang.reflect.Method .invoke call.

  I came across the same thing as you. I did a lot of experimenting and found it works:

  var result = (function() {
      var ReflectiveArray = java.lang.reflect.Array;
      var CreateSQL = Packages.PeopleSoft.PeopleCode.Func.CreateSQL;
      var columns = ReflectiveArray.newInstance(java.lang.Object, 1 /* number of selected columns */);
      var results = [];
  
      SQL = CreateSQL("SELECT OPRDEFNDESC FROM PSOPRDEFN WHERE ROWNUM < 10");
      while (SQL.Fetch(columns)) {
          results.push(columns[0]);
      }
  
      return results.join();
  
  }());
  

  He seems to have been a problem with translation between the JavaScript array and the Java array Object []. I solved this by using java.lang.reflect.Array.newInstance to create a new instance of the object [1].

  Next issue to deal with is your memory problem. In the error message, it seems to have something to do with the Garbage Collection and a lot of temporary objects. You declare you line and cell by using the var =... line and cell var =...? If not, then they are in the global namespace and properties of the global object. At the end of each iteration of the loop, use delete line and delete cells. If you declare the var, then set their value null at the end of each iteration. Based on your code, I expect each time through the loop would decrease the number of references, but I saw where setting explicitly using null. The only other temporary object I see is the value in the table. Just for fun, I added this at the end of each loop, and he ran very well:

  columns[0] = null;
  

• JDeveloper Extension Project does not have a class of jar - java.lang.NoClassDefFoundError

  I created a JDeveloper extension project, I need to see some external pots according to my condition. I added the jar to the project and I'm not facing problems at compile time. But when I run my extension, I get the following error:

  class java.lang.NoClassDefFoundError: < subject >

  .

  .

  Caused by: oracle.classloader.util.AnnotatedClassNotFoundException

  I tried the following options:

  1 added the pots to the project

  2. Add the jars as library

  3 referenced by MANIFEST pots. MF file

  But none of the above worked for me. The pots are getting delivered with my ExtensionProject.jar, but even when I add the extension for JDeveloper, it does not work.

  I am using JDev version 11.1.1.6

  Finally, this solved!

  The pots should be added as dependencies in the expansion project extension.xml file.

  Hello everyone

  I use JDeveloper version 11.1.2.3.0 and iReport 5.1.0.

  I created an application where users can upload their own jrxml files, these files get compiled and stored in the FS. When users need to create PDF reports, they can select one of the types of reports from those downloaded and generate the report.

  Everything worked fine at first, but after a few tries, I got this error, only on the report part of filling:

  ... more than 44

  I saw several posts about this error, saying that there could be more than one reference in the same container, or two pots imported with the same content/dependencies.

  Here is the list of the pots that I use in my application:

  -groovy-all - 2.0.1

  -iText - 2.1.7.js2

  -jasperreports - 5.1.0

  -jasperreports-fonts - 5.0.4

  -3, 7 - poi poi-ooxml-3, 7

  -commons-io - 2.4

  (over a few other commons-* jars not related).

  These are the same that I used when the application is running, more I used Jasper before and never had this error.

  Help, please!

  Thanks in advance.

  Thnx everyone who responded.

  I'll give you some information since I've solved, and I'm not delete this post someone else might find it useful.

  First of all, as I said in the original post, he worked well at first. This is because I was using some empty reports with no data inside, and in the very first attempt to insert a static text again, the error above was deleted. It might even work if you remove the text. This is a result of the language property of the report itself which is default Groovy. The problem seems to be a sort of double method called from the libraries of groovy and jasperreports imported in the class path.

  Solution: I changed the language of Groovy in Java, in the properties of the report. Then used this static method for compiling:

  JasperCompileManager.compileReport (design);

  This will require to include jdt - compile in the classpath, you can find it in the lib of JasperReports.

  I hope this post can help others.

  Kind regards!

• Unable to see java.lang.string in IOM utility API

  Hello
  
  I am not able to see java.lang.string and java.lang.object in IOM utility API when an adapter of the entity is created. Here's what I did
  
  (1) created a feature adapter
  (2) adding a task
  (3) selected utility, and then click utility (excluding the two selection utility options or IOM Thor APIs)
  (4) creates a new instance
  (5) tried to select java.lang. string in the API of the application which I am not able to find.
  
  Please let me know if this could be a problem with installation or some jar file missing.
  
  Thank you
  
  Rahul Sharma

  I tried the workaround below...

  In the adapter factory
  1. click on add a new task
  2. Select utility-> utility
  3. in the drop-down list, select tcUtilStringOperations and methods drop-down list, select the holdData() method
  4. map to the input to your string variable variable
  5. no need to map output variable. Click Save
  6. click on add new task
  7. Select utility-> utility
  8 to object of the Instance selection, select the 'task return value instance' radio button and select the task of the adapter which was created above
  9. click on continue.

  Now you'll see java.lang.string API with all the methods under him.

  I followed this approach to make use of the API of the chain. Experts in our forum can help you the best ways to see it.
