Operator ' ' undefined for type K

Hey,
Trying to implement a binary search tree.
I can't get the search feature working...
I keep getting this error:
The operator < is undefined for the argument type(s) K, K BinarySearchTree/src/myPackage BSTree.java line 35 similarly for '>'http://www.darkdayssoftware.com/BSTree.java
http://www.darkdayssoftware.com/TreeNode.java
Any Help much appreciated.

Without wishing to state the obvious, the error message is simply telling you that the two operators cannot be used to make comparisons between objects of that particular class. Remember that Java - unlike C++ - does not support operator overloading so it is not always possible to use all of the operators to perform comparisons between different objects. It is quite likely that you would see a similar message if you tried to compare two Strings using these operators.

               System.out.println(t);
Test2[] passArray = new Test2[4];
testArray(passArray); // error: Method testArray(Test2[]) is undefined for type Test.Also, for future reference, how do I format the code for this forum so that it has proper indentation and is easier to read? Thanks.

Unsupported operation read for type realm

Hi everybody,
I'm trying to list the realms of the Top organisation with this code:
("token" is the SSOToken of a valid amadmin session)
     try
         AMIdentityRepository idRepo = new AMIdentityRepository(token, "");
         IdSearchControl controlSearch = new IdSearchControl();
         controlSearch.setMaxResults(1);
         IdSearchResults resultSearch = idRepo.searchIdentities(IdType.REALM, "*", controlSearch);
         Iterator orgListIterator = resultSearch.getSearchResults().iterator();
         if (orgListIterator.hasNext())
          AMIdentity org = (AMIdentity) orgListIterator.next();
          return org.getMembers(IdType.REALM);
     catch (Exception ex)
         ex.printStackTrace();
     }But I'm getting this error:
Plug-in com.iplanet.am.sdk.AMSDKRepo does not support operation read for type realmFor children organisations (like "business"), the Set returned by getMembers() is empty...
Any idea??
thanks

It's the price we "early adopters" pay. It usually takes a few weeks to even months before Apple and Adobe add support for the latest RAW camera profiles. There is no standard RAW format, even within a brand. It's maddening, but that is the nature of the format.
For now all we can do is either shoot JPEG and grin and bear it or shoot JPEG + RAW, and when RAW support is available trash the JPEGs and upload the RAWs. Or in your case use the 5000 when you absolutely need RAW.

Generated servlet error: method is undefined for type

Hi,
I keep getting the following error when I attempt to run my JSP:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 12 in the jsp file: /jsp-examples/JSPandMySQL/loginuser.jsp
Generated servlet error:
The method getValidUser() is undefined for the type LoginDetails
In my JSP file I have the code:
<%
boolean validName = login.getValidUser();
if(validName == false) {
out.println("Invalid Username");
} else {
out.println("Valid Username");
%>
and the method getValidUser(); is in a Java Bean that I have created and the code for that method is just :
public boolean getValidUser() {
return valid;
I've tried searching the net for some answers but none of the solutions given work for mine, I would be grateful for any advice on how to solve this program.

DId you import the class at the top of the jSP? Does the method exist? Is the class compiled properly?

Hi ,
I have a method defined in my dataManagerDAO classIs it dataManagerDAO or DataManagerDAO?
getNoc( strRppsId) throws Exception {}That's not a legal Java method declaration, so it's clearly not your actual declaration, so I have no idea what your actual declaration is, so I can't tell you what you're doing wrong.
Now I am calling this method inside my JSP page :
DataManagerDAO dataMgr = new DataManagerDAO();
dataMgr.getNoc(strRppsId)..
But whenver I am running it locally , it fails to compile and gives following error msg :
The method getNoc(String) is undefined for the type DataManagerDAOQuite obviously you're calling a method getNoc(String) but that method doesn't exist on the DataManagerDAO class. No matter how much you may think you know that it does, you're wrong and the compiler is right.
Maybe you misspelled or mis-capitalized something. Maybe you're passing the wrong type of argument. Maybe you're still using an older version of the DataManagerDAO class from before you added that method. Not enough information here to say for sure.
ny clue wats going wrong in here ?I assume you mean "any", not "ny" and "what's", not "wats". Clear, correct, precise communication counts with folks here almost as much as it does with the Java compiler.

PreparedStatement.getGeneratedKeys(): undefined for the type PreparedState

All,
I'm getting this exception:
"The method getGeneratedKeys() is undefined for the type PreparedStatement" When I try to run this code:
Connection con = (Connection)getConnection();
PreparedStatement stmt = null;
stmt = con.prepareStatement("INSERT INTO article (title, description, creationDate, createdBy) VALUES (?,?,?,?)");
stmt.setString(1, title);
stmt.setString(2, description);
stmt.setDate(3, creationDate);
stmt.setInt(4, createdBy);
stmt.executeUpdate();
ResultSet rs = stmt.getGeneratedKeys();Javadoc says PreparedStatement inherits getGeneratedKeys() from Statement. Then why does it go wrong?
Thanks alot!

No sorry, it is a compile time error.
But I've solved the problem.
I'm using WSAD and it was pointing to the wrong rt.jar (the one that comes with WSAD). I've changed it to the sun rt.jar and now it works fine!
Thanks anyway!

Chris,
I'm not a database guy - so in many ways, I'm not really qualified to answer this, but I'll make a suggestion anyway:
At the very top of your code, put the following:
Option Strict On
Option Explicit On
Option Infer Off
With strict on and infer off, it will force you declare types - which I see missing in many places in the code.
It's entirely possible that by you then going through and fixing those issues, you'll have corrected the problem.
I don't know that, but it's possible -- and it should be done this way anyway, so there's certainly no harm to be done; in fact you'll actually speed up the program to a small degree because objects don't have to be inferred for the type that they actually
are.
***** EDIT *****
Also this: DON'T declare any of the types simply as "Object"; that's just trading off late binding for boxing, so you haven't really done much good. Declare them each as their correct actual type.
Still lost in code, just at a little higher level.

Popup Key LOV, NULL and "Invalid numeric value undefined for column"

Hello.
I've created an item based on database column of NUMBER type and set the following properties:
Display As = Popup Key LOV (Displays description, returns key value)
List of values definition=select 'display_value' d, 1 r from dual
Null display value=%
Null return value=
Display Null=Yes
When I select "%" in the LOV and try to apply changes to database I get error:
ORA-20001: Error in DML: p_rowid=1781, p_alt_rowid=N1, p_rowid2=, p_alt_rowid2=. ORA-20001: Invalid numeric value undefined for column N2
Error Unable to process row of table TTT.
If I set Display As = Select List, all works fine. But I need Popup Key LOV.
Could anybody help me?
I use Application Express 2.2.1.00.04

Hi all,
I did my homework and solved this issue. First I would like to thank Patrick Wolf for the invaluable help he gives out on thread Re: Null value handling in LOVs The code presented here is just a minor edit to his code, but an essential one when dealing with Popup Key LOV items.
Here's what I did:
1. Create an Application Process.
Name: RemoveNulls
Sequence: 0
Point: On Submit: After Page Submission - Before Computations and Validations
Process Text:
BEGIN
    FOR rItem IN
      ( SELECT ITEM_NAME
          FROM APEX_APPLICATION_PAGE_ITEMS
         WHERE APPLICATION_ID   = TO_NUMBER(:APP_ID)
           AND PAGE_ID          IN (TO_NUMBER(:APP_PAGE_ID), 0)
           AND LOV_DISPLAY_NULL = 'Yes'
           AND LOV_DEFINITION   IS NOT NULL
           AND LOV_NULL_VALUE   IS NULL
    LOOP
        IF (V(rItem.ITEM_NAME) = '%null' || '%' OR V(rItem.ITEM_NAME) = 'undefined')
        THEN
            Apex_Util.set_session_state(rItem.ITEM_NAME, NULL);
        END IF;
    END LOOP;
END;Error Message: #SQLERRM#Condition: None
2. You should be able to submit a Popup Key LOV with a NULL value now.
Once again, THANKS, Patrick! You rock! I'm seriously thinking of trying ApexLib now :)

The Spring bean which is exposed as a Remote Object has the following method signature..

        return mapKey;
[/CODE]
I am unable to understand why AMF Channel or Blaze DS is treating the String as HashMap !!!
This was working pefectly fine till yesterday !!
The version of the BlazeDS i am using is : blazeds_turnkey_3-0-0-544
and the Flex SDK Version is : flex_sdk_3.5.0.12683
We recently upgraded to Flex 3.5.0 version earlier we were using 3.3 version
Thanks

Hi All,
I chcked my server side java beans ( which are managed by Spring) and they are all returning the data property and none of the Keys in the returned hashmaps are null.
Not sure why this is happening.
Thanks

Ok, this may not be your problem, but I was getting this error as well.
I had multiple services running, and I was able to use SOAP test clients and connect to them and get responses, no problem.
I wrote some client code to connect to one, and it worked just fine.
Then I wrote some client code to connect to the other, and I got an error like
faultString: org.xml.sax.SAXException: Deserializing parameter 'initiateIn': could not find deserializer for type {urn:SOAPFulfillmentAPI}DoSomething
...I tore my hair out trying to figure out why a service that functions perfectly using other tests would fail in java. Then I realized I was pointing to the end point URL.
It looks like AJAX tries to deserialize the parameters before it does any of basic sanity check to see the method your looking for even exists (even in debug mode). So instead of getting a useful error like "Cant find method 'DoSomething' " you get some crap about not being able to understand the datatype for an arguement.
I hope this helps someone one day =)

Custom iterator problem - The method createChildIterator() is undefined for

Hi there, this is my first post here, still quite new to Java. I'm having trouble with a custom iterator when trying to test it with JUnit. The reason to write a custom iterator is this: I want to get the object in the array, then for each item I want to get it's child items with a new iterator call.
It's quite complicated because naturally I'm trying to hide the implementation from the "user". The iterator holds a list of classes called StandardSortElement. Each of these classes holds a class called AvailableResouce
which in turn holds an AbstractResource, and it's AbstractResource that I want the iterator to return. My JUnit testing shows that this part works correctly.
For the child items, they are also held inside the StandardSortElement as an array list. Here is the error I get
"The method createChildIterator() is undefined for the type Iterator<AbstractResource>"
First here is an interface for the custom iterator:
public interface SortIteratorInterface extends Iterator<AbstractResource>{
     public abstract Iterator<BookingInterface> createChildIterator();
}Here is the iterator class:
public class StandardSortIterator implements SortIteratorInterface {
     ArrayList<StandardSortElement> items;
     Integer position = 0;
     * a constructor that passes in a sorted list of StandardSortElement
     public StandardSortIterator(ArrayList<StandardSortElement> items) {
          this.items = items;
     * Return bookings associated with the currently iterated StandardSortElement
     public Iterator<BookingInterface> createChildIterator() {
          return items.get(position).createBookingIterator();
     * Determine if there is another item in the list
     public boolean hasNext() {
          if (position >= items.size()) {
               return false;
          } else {
               return true;
     * Return the next resource in the list. We have a list of StandardSortElement but
     * we want to return the resource within.
     public AbstractResource next() {
          StandardSortElement ssa = items.get(position);                                             // Get a handle on the StandardSortElement
          AbstractResource ar = ssa.getResource();                                                  // Now get the resource that's packaged up inside
          position++;                                                                                          // Increment the position
          return ar;                                                                                          // return the resource
     * Do not implement - mandatory interface implementation but not required here.
     public void remove() {
          // TODO Auto-generated method stub
}This is the code taken from the JUnit test class
     * This iterator also has an interal child iterator. Check this works as expected
     @Test
     public void testChildIterator() {
          Iterator<AbstractResource> iterator = new StandardSortIterator(items);
          Integer i = 0;
          while (iterator.hasNext()) {
               AbstractResource abstractResource = (AbstractResource)iterator.next();
                if (i.equals(0)) {
                     // The first element should contain children - check it works
                     Iterator<BookingInterface> childIterator = iterator.createChildIterator(); // ERROR OCCURS HERE
               i++;
          assertTrue(i.equals(items.size()));
     /************************************************************************************/Thank you in advance for any help you can provide!

Your unit test is coded against the Iterator interface, not your SortIteratorInterface, which is where the createChildIterator method is defined. You need to use a reference to a SortIteratorInterface, not an Iterator. Incidentally, when defining an interface, it's unnecessary to declare the methods as public and abstract. They're implicitly that anyway

Process and initiate operations in port types

What is the difference between the process and initiate operation in the port types definition found in wsdl file? Is this used too define sync and async processes?

Hi.
As far as I understand, process and initiate are just naming conventions. What really makes the difference is that, for sync processes you have a single portType with an input/output operation, and for async processes you have two portType definitions, each one containing an input only operation.
For sync processes, the requestor makes the call and waits for the response, using the same channel (same port).
For async processes, the requestor makes the call in one port and forget about it. Later on, a callback can be generated through the other port type as a means of notifying the requestor back in an async way.

Hi Muthu,
Thanks for your quick response. Now I solved the issue of product category. Actually problem was that, we have huge number of product categories (approx 2000) and I have maintained (*) in attribute. So when system is searching for product categories, it takes lots of time and later it time outs. Now I have maintained a small range of category in attribute and it works.
Now one more problem is coming. When I am trying to check or save the shopping cart system throwing a short dump. Kindly help

Problems in Operator Interface for LabVIEW

Hi Ray,
I am using LabVIEW 7.0 and TestStand 2.0 version. I am using the default operator interface for labVIEW provided in the TestStand and i am using custom step types in my sequence file.
This sequence calls a VI, which transmits strings that i specify from the serial port to the NI-7831 RIO Fpga Card for differnt baud rates. The same sequence is working fine when called from Sequence Editor but it is not working when it is called from Operator Interface for LAbVIEW. It justs either fails the test or skips them. Please tell me if there is any solution for it. I have attached the sequence file and the vi that i am calling from my sequence file.

Hi,
You forgot to attach your sequencefile and VI, but never mind.
I think the problem maybe that because you are using the default Operator Interface.
If it still the one in the NI folder, then you will have to re build the testexec.exe application using your LabVIEW 7.0 Application Builder. The default exe file has been built using LabVIEW 5.1.1
Before you start, copy the LV folder from OperatorInterfaces\NI\ to OperatorInterfaces\User.
Load the testexec.bld file in your Application Builder and rebuild testexec.exe.
Launch your new testexec.exe from the User\lV folder and retry your test sequencefile.
Hopefully that should cure your problem.
