NDM nearestNeighbors method with GoalNode filter
Hello everyone,
I'm trying to use the NetworkManager.nearestNeighbours method of the NDM Java API to find the path to the nearest node of a certain type. I am using the PARTITION_ID field to categorize the nodes, and the goal nodes I have in mind are of a certain partition (1). The network is directed, I'm using 10g Release 2, it has about 12000 edges and 8000 nodes.
The method invoking looks like this:
Path[] nPaths = NetworkManager.nearestNeighbors(network, startNodeId, 1, null, new HighwayGoalNode(1));
and the HighwayGoalNode class implementation:
public class HighwayGoalNode implements GoalNode {
private int partitionID;
public HighwayGoalNode(int partitionID) {
this.partitionID = partitionID;
public boolean isGoal(Node node) {
System.err.println(node.getID());
if(node.getPartitionID() == partitionID) {
return true;
} else {
return false;
My problem is this: for most of the cases (i.e. startNodeId s), the method returns null (no exceptions are thrown). If I change the noOfNeighbors parameter to 2 while keeping the same startNodeId, the method sometimes returns a path array, but still most of the times it's of length 1, even though a quick look at the graph indicates there ARE 2 (or even more) solutions.
For instance, there are cases where I invoke the method, and the System.err printout of the nodes checked by the GoalNodes filter shows that about 5 nodes in all were checked!. These are NOT dead-ends OR cycle points, the method SHOULD be able to go past them and check more nodes... And it DOES, if I just don't use the filter...
What's happening? I don't think I'm doing anything wrong, and I really don't have the time to build test networks to figure this out, I'm guessing there's a bug in the api code, could someone please confirm it or else give me a solution?...
Thank you,
Kostis Pristouris
Hey Kostis,
It is a bug. I just filed it on your behalf.
Thanks for using NDM!

I have Problem with Extract Filter which was working OK until recently.
Now, when I choose the filter the screen does not come up as the extract screen as it should and no other action can be taken except to press escape which returns me to normal. working. Looks as if the extraction function has been sleected but does not show?
I am trying to use the extract on a layer. Have tried to use it on a selection also.
Anyone suggest a solution please?
BillWithout a way to reset the tool, the only possibility seems to be to reset your preferences as described in the FAQ.

You either have to physically delete (or rename) the preference files or, if using the Alt, Ctrl, and Shift method, be sure that you get a confirmation dialog.
This resets all settings in Photoshop to factory defaults.

Strange Problem with InKeyset filter
I encountered a strange problem with inkeyset filter.I am trying to do some operations on the the selected set of keys within a cache. I have posted the psuedo code below
InKeySetFilter inKeySet=new InKeySetFilter(AlwaysFilter.INSTANCE,orgDestFlightSubset);
// Set of Keys for NamedCacheInstance
inKeySet.ensureConverted
(NamedCacheInstance.getCacheService().getBackingMapManager().getContext().getKeyToInternalConverter());
Extra code to be Added
System.out.println(NamedCacheInstance.entrySet(inKeySet).size());
Always prints 0 eventhoug the keys are present in cache. If i add the following code
NamedCacheInstance.get(orgDestFlightSubset.toArray()[0]) above printing it gives 1 as a result.
I am sure that object is in cache becoz cache.get() does not call the DB again
Can anyone tell me what could be the possible problem?Hi,

In this case you should not call the ensureConverted method. This is called by Coherence on the storage nodes upon deserializing of the filter.
Try these changes.

I would love some help with this issue. I have configured my SharePoint foundation 2010 site to use Claims Based Auth with Certificate authentication method with ADFS 2.0 I have a test account set up with lab.acme.com to use the ACS.
When I log into my site using Windows Auth, everything is great. However when I log in and select my ACS token issuer, I get sent, to the logon page of the ADFS, after selected the ADFS method. My browser prompt me which Certificate identity I want
to use to log in and after 3-5 second
and return me the logon page with error message “Authentication failed”
I base my setup on the technet article

A question about a method with generic bounded type parameter
Hello everybody,
Sorry, if I ask a question which seems basic, but
I'm new to generic types. My problem is about a method
with a bounded type parameter. Consider the following
situation:
abstract class A{ }
class B extends A{ }
abstract class C
public abstract <T extends A> T someMethod();
public class Test extends C
public <T extends A> T someMethod()
return new B();
}What I want to do inside the method someMethod in the class Test, is to
return an instance of the class B.
Normally, I'm supposed to be able to do that, because an instance of
B is also an instance of A (because B extends A).
However I cannot compile this program, and here is the error message:
Test.java:16: incompatible types
found : B
required: T
return new B();
^
1 errorany idea?
many thanks,Hello again,
First of all, thank you very much for all the answers. After I posted the comment, I worked on the program
and I understood that in fact, as spoon_ says the only returned value can be null.
I'm agree that I asked you a very strange (and a bit stupid) question. Actually, during recent months,
I have been working with cryptography API Core in Java. I understood that there are classes and
interfaces for defining keys and key factories specification, such as KeySpec (interface) and
KeyFactorySpi (abstract class). I wanted to have some experience with these classes in order to
understand them better. So I created a class implementing the interface KeySpec, following by a
corresponding Key subclass (with some XOR algorithm that I defined myself) and everything was
compiled (JDK 1.6) and worked perfectly. Except that, when I wanted to implement a factory spi
for my classes, I saw for the first time this strange method header:
protected abstract <T extends KeySpec> T engineGetKeySpec
(Key key, Class<T> keySpec) throws InvalidKeySpecExceptionThat's why yesterday, I gave you a similar example with the classes A, B, ...
in order to not to open a complicated security discussion but just to explain the ambiguous
part for me, that is, the use of T generic parameter.
The abstract class KeyFactorySpi was defined by Sun Microsystem, in order to give to security
providers, the possibility to implement cryptography services and algorithms according to a given
RFC (or whatever technical document). The methods in this class are invoked inside the
KeyFactory class (If you have installed the JDK sources provided by Sun, You can
verify this, by looking the source code of the KeyFactory class.) So here the T parameter is a
key specification, that is, a class that implements the interface KeySpec and this class is often
defined by the provider and not Sun.
stefan.schulz wrote:
>
If you define the method to return some bound T that extends A, you cannot
return a B, because T would be declared externally at invocation time.
The definition of T as is does not make sense at all.>
He is absolutely right about that, but the problem is, as I said, here we are
talking about the implementation and not the invocation. The implementation is done
by the provider whereas the invocation is done by Sun in the class KeyFactory.
So there are completely separated.
Therefore I wonder, how a provider can finally impelment this method??
Besides, dannyyates wrote
>
Find whoever wrote the signature and shoot them. Then rewrite their code.
Actually, before you shoot them, ask them what they were trying to achieve that
is different from my first suggestion!
>
As I said, I didn't choose this method header and I'm completely agree
with your suggestion, the following method header will do the job very well
protected abstract KeySpec engineGetKeySpec (Key key, KeySpec key_spec)
throws InvalidKeySpecException and personally I don't see any interest in using a generic bounded parameter T
in this method header definition.
Once agin, thanks a lot for the answers. -
How do you invoke a method with native int array argument?
Hi,
Will someone help me to show me a few codes samples on how to invoke a method which has only one argument, an int [] array.
For exampe:
public void Method1(int [] intArray) {...};
Here is some simple code fragment I used:
Class<?> aClass = Class.forName("Test2");
Class[] argTypes = new Class[] {int[].class};
Method method = aClass.getDeclaredMethod("Method_1", argTypes);
int [] intArray = new int[] {111, 222, 333};
Object [] args = new Object[1];
args[0] = Array.newInstance(int.class, intArray);
method.invoke(aClass, args);I can compile without any error, but when runs, it died in the "invoke" statement with:
Exception in thread "main" java.lang.IllegalArgumentException: object is not an instance of declaring class
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
at java.lang.reflect.Method.invoke(Unknown Source)
at Test1.invoke_Method_1(Test1.java:262)
at Test1.start(Test1.java:33)
at Test1.main(Test1.java:12)
Any help is greatly appreciated!
JeffSorry, my bad. I was able to invoke static methods and instance methods with all data types except native int, short, double and float, not sure the proper ways to declare them.
After many frustrating hours, I posted the message for help, but at that time, my mind was so numb that I created a faulted example because I cut and pasted the static method invocation example to test the instance method passing int array argument.
As your post suggested, "args[0] = intArray;", that works. Thanks!
You know, I did tried passing the argument like that first, but because I was not declaring the type properly, I ended up messing up the actual passing as well as the instantiation step.
I will honestly slap my hand three times.

Issue with parameter/filter - trying to display null rows
This is how my data looks in the database
Order_ID ----- Vendor
ID123 NULL
ID234 ABC
ID456 NULL
ID001 CDE
I want to create an SSRS report with a filter for vendors
*All Vendors should be checked off by default
*Users should be able to select multiple vendors
So I started by creating the VendorDataSet, the query looks like
SELECT VendorName
FROM Vendor
WHERE Active = 1
*This query will return all active vendors stored in my vendor table
Then, I created my parameter @prmVendor and it looks like:
-Data Type: Text
-Allow blank value("")
-Allow multiples values
Available Values:
-Dataset: Vendor
-Value field: vendor_name
-Label field: vendor_name
The main query of the report looks like
Select Order_ID, Vendor
FROM Order
LEFT JOIN Vendors
ON Order.VendorID = Vendor.ID
WHERE Vendor IN (@prmVendor)
So at this point it does what is supposed to do except - that when I run the query with all the vendors selected,
the query will only return the ones with vendors populated.
Order_ID ----- Vendor
ID234 ABC
ID001 CDE
I've tried adding the following to my VendorDataSet:
SELECT VendorName
FROM Vendor
WHERE Active = 1
UNION ALL
SELECT '' -- I've also tried SELECT NULL
But when I run the report and look at the list of vendor displayed - it won't show the empty row in the vendor drop down filter
thus, my main query will ignore the orders with no vendors.
Any ideas on how to fix this issue?
-AlanSo I changed my VendorDataSet to look like this:
;WITH cteVendors AS (
SELECT VendorName
FROM Vendor
WHERE Active = 1
UNION ALL
SELECT ''
SELECT (CASE WHEN Vendor IS NULL THEN '' ELSE Vendor END) AS VendorName
FROM cteVendors
This allowed me to show an empty box in my drop down filter see link for
image
Is there a way to make some changes to my main query so this works? so if the user was to select the blank box the query will return something like :
Order_ID ----- Vendor
ID123 NULL
ID456 NULL

Trying to Imitate the html POST method with an applet
I am trying to imitate the POST method with an applet, so that I can eventually send sound from a microphone to a PHP script which will store it in a file on a server. I am starting out by trying to post a simple line of text by making the PHP script think that it is receiving the text within a POST-ed file. The reason I am doing things this way is in part because I am, for the time being, limited to a shared server without any support for servlets or any other server side java.
The code I am trying is based in part on an old thread found elsewhere in this forum, concerning sending data to a PHP file by imitating the POST method:
link:
http://forum.java.sun.com/thread.jspa?threadID=530399&messageID=2603608
someone named "harmmeijer" provided most of the answers on that thread. If that person is still around hope they take a look at this,also I have some questions to clarify what they said on the other thread..
My first attempt at code is below. The applet is in a signed jar file and is trying to pass a text line to the PHP script in the same directory and on the same server that the applet came from. It is doing this by sending header information that is supposed to be identical to what an html form would send if it was uploading a .txt file with the line of text within it. The applet displays one button. When you press it, it sucessfully starts up the postsim method (defined at the end), which is supposed to send the info to the PHP script at the server.
I have two questions:
1) I know that the PHP script is starting up, because it prints out a few messages depending on what happens. However, the script does not recognize any file coming down the line, so it does not save anyting on the server, and prints out a message saying the no file was uploaded.
Any idea what might be going wrong? I'm not getting any error messages from the applet. I've tried a few different variations of the 'header' information contained in the line:
osToServer.writeBytes("--****4353\r\nContent-Disposition: form-data; name=\"testfile\"; filename=\"C:testfile.txt\"\r\nContent-Type: text/plain\r\n");
The commented out line below it shows one variation (which was given in the thread mentioned above).
2) You'll notice that I've commented out the two lines having to do with the input line:
//InputStream isFromServer;
and
//isFromServer = uc.getInputStream();
The reason is that the program crahes whenever I put the latter line in - to the extent that Opera closes down the JVM and then crashes when I tried to exit it.. I must be doing something horribly wrong there! I first tried using isFromServer = new DataInputStream(uc.getInputStream());
becuase it was consistent with the output stream, but that caused the same problem.
Here's the code:
public class AudioUptest1 extends Applet{
//There are a few spurious things defined in this section, having to do with the fact the microphone data is evenuatly going to be sent. haven't yet insterted code to get input from a microphone.
AudioFormat audioFormat;

uc.setRequestProperty("Connection", "Keep-Alive");
uc.setRequestProperty("HTTP_REFERER", "http://applet.getcodebase");
uc.setRequestProperty("Content-Type","multipart/form-data; boundary=****4353");
osToServer = new DataOutputStream(uc.getOutputStream());
//isFromServer = uc.getInputStream();
catch(IOException e)
System.out.println ("Error etc. etc.");
return;

ActionEvent e){

I was trying to write a signed applet that helps the
user of the applet to browse the local hard disk and
select a file from the same. The JFileChooser class
from Swing is what I used in my applet. The problem
is with the policy file. I am not able to trace the
exact way to write a policy file which gives a total
access to read,write,delete,execute on all the drives
of the local hard disk.
I am successful in signing the applets and performing
operations : read,write,delete & execute on a single
file but failing to grant permission for the entire
file.
Any help would be highly appreciated.Which policy file are you using? there might be more than one policy file.
also, u have to specify the alias of the signed certificate in the policy file to grant the necessary priviledges to the signed applet. -

Building a method with more than one result data
Hi, everyone:
I'm a little shy to ask this question, however, it's been hanging in my mind for so long, so I think I'd rather make a confession on it. You may laugh at me if you want, I'm ready for that, but I more look forward to that someone can really give me the light, or even the link, or some hint....
For your ease of reading, I give the question first, and my whole story behind:
When I need a method which can provide more than one result( in other words, multiple outputs), how can I do it in Java? As I know, either you pass and object, or the result of the function is an object will do , for the object contains the datas you want, but that means your needs for those data have to be defined in object format in advance, won't that be inconvinient? Or Java has a better solution for that?
//And here's the whole story....
I began my career as a programmer by starting with LabVIEW, it's a graphical programming language made by National Instrument, and it's powerful on DAQ, and industrial field. One of the most important issues on design is to devide your system into multiple functions( in its own term: subVI), I think it's just like applying structured analysis method.
When we dealing with functions in LabVIEW, a programmer can define his own function with mulitiple inputs and outputs, for example, I can design a function called SumAndDevide, which accepts two input ( two variables to be summed and devided) and gives two results( result of summing and that of deviding).
The methodology has its power, at least it provide the functional decomposition, and you can compose a suitable solution in certain circumstance even they are not the smallest unit function. And testing is easy. It affects me so large that I look the trail of it when I come to other programming languages. In COBOL( well, that is a VERY old COBOL version ), I was scared to find there is no protection to the inner data on the performed sections, while making a outside subroutine to be called is cubersome and really a hard work. When I came to Delphi, I knew that using the result of a function cannot satisfy me, for it give only one output, even you can define it as variant, but I think it's vague to realize. So I use the difference of called by value and called by reference to handle the problem, that is: a value parameter for the input, and a variable paramter for the output.
Well, when I came to Java, I am stunned again, now there is no passing by reference mechanism in Java, otherwise you have to pass it as an object, but that means when you need multiple outputs, the output has to be defined in object form in advance. And that will be very inconvinient!! I tried to find some solutions, but I can't. So is there any way that in Java you can define a method with multiple output? or Java handles the problem in totally different way?
Any comments will be appreciated!!
Thanks!!
aQunx from TaiwanYou missed the most common OO solution - separation of concerns and implementation hiding.
If you have a function which returns a string, that is one method of the object that provides the service.
If you have a function which returns a real, that is a different method of the object.
If both functions require common code, move that into a private method which is called by both. If the method is costly, cache the result.
eg an aerodynamics properties class, which could be done as a multivalued return of (lift, drag), refactored to independent lift() and drag() methods, which delegate to an interpolate() method, which caches the interpolated value and uses mach, pressureHeight and _alpha to determine whether it should recalculate: /**
* Calculates the aerodynamic drag force at a given mach, alpha and pressure height.
public double drag (final double aMach, final double aPressureHeight, final double aAlpha) {
interpolate(aMach, aPressureHeight, aAlpha);
return _drag;
* Calculates the aerodynamic lift force at a given mach, alpha and pressure height.
public double lift (final double aMach, final double aPressureHeight, final double aAlpha) {
interpolate(aMach, aPressureHeight, aAlpha);
return _lift;
private void interpolate (final double aMach, final double aPressureHeight, final double aAlpha) {
if (aMach != _mach) {
setMach(aMach);
_pressureHeight = Double.NaN;
if (aPressureHeight != _pressureHeight) {
setPressureHeight(aPressureHeight);
_alpha = Double.NaN;
if (aAlpha != _alpha) {
setAlpha(aAlpha);
... actual interpolation happens in the private setXXX methods. -
I want to find a bookmark in its location in the hierarchy of bookmarks, but all I can do with the filter is isolate a bookmark[s]; either using the filter of the bookmarks sidebar, or in the ShowAllBookmarks window. For instance, I know I have a certain bookmark, but I want to move it into a new "folder" and rename it, perhaps; for this I need to be able to *see* it in the hierarchy, as in the Finder of a Mac, when the filter turns up a file, then "Show Original" of "Open Enclosing Folder."
I'm just trying to understand how to use these add-ons, having just added them on, to borrow a phrase, but have now found a comment re Go Parent Folder, "This extension does not seem to work in MacOS X. " <http://forums.mozillazine.org/viewtopic.php?t=659690>. Sadly [altho I really like Snow Leopard] I'm running OS X.6.7. Nonetheless a contextual menu mousing down on a "found" bookmark indeed does give the working option of "Go to Parent Folder" from the found list of the ShowAllBookmarks window, *or* the that of the sidebar window. Bravo!!
Just a question again, how would I have learned this had I not bothered the entire forum, and taken cor-el's time/effort? -
How to call a AM method with parameters from Managed Bean?
Hi Everyone,
I have a situation where I need to call AM method (setDefaultSubInv) from Managed bean, under Value change Listner method. Here is what I am doing, I have added AM method on to the page bindings, then in bean calling this
Class[] paramTypes = { };
Object[] params = { } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
String aVal = "test";
Class[] paramTypes = {String.class };
Object[] params = {aVal } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
Thanks,
San.Simply do the following
1- Make your Method in Client Interface.
2- Add it to Page Def.
3- Customize your Script Like the below one to Achieve your goal.
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap().put("username", "oracle");
operationBinding.getParamsMap().put("role", "F1211");
operationBinding.getParamsMap().put("Connection", "JDBC");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
i hope it help you
thanks -

The filtered field is a list of choices with no multiples values.
I'm pretty sure the issue is located here :

What can I do ?
Thanks
Best regards / BenHi Ben,
How did you design the filter on the view?
This error usually occurred when people use SQL T-SQL. Here are two similar posts , please check whether they are useful for you:
http://social.technet.microsoft.com/Forums/en-US/e1ba76f9-855f-4087-91a7-c3e492e59be4/conversion-failed-when-converting-the-nvarchar-value-xxxxxx-to-data-type-int?forum=transactsql

Please create a new list, and create a new view, then add a filter on the view, compare the result.
I hope this helps.
Thanks,

JSR 172: error while invoking methods with the same signature
Hi
I am facing a peculiar problem which is not making sense to me. This is what I have done:
1. Written a simple web service that has two methods: sayHello and sayHellToMe. Both these methods have same signatures. They do not take in any parameter and return a string.
2. Deployed this web service (document/literal) type on Axis 1.2
3. Generated the stub classes from the wsdl file using Sun Wireless Toolkit's Stub Generator
4. I have now written a MIDlet that uses this stub class to invoke both the methods one after the other.
I enabled SOAPMonitor on Axis and saw the SOAP Request and SOAP Response messages. I observed the following:
1. In the first method: sayHello - everything works fine (with a few tweaks in the Stub class)
2. However, while invoking the second method sayHelloToMe, the SOAP Body tag in the SOAP Request does not contain any method name. I checked out the Stub class, the qnames and the types are all correct..
I also realized that this behavior is seen only when I have methods with the same signature in the web service. Any idea why this might be happening? It seems like a very weird problem.
Any help in this regard will be greatly appreciated.
Thanks,

Calling a method with a string
Here's the question:
I want to call a method with the name equal to a string variable.
For example, if the string variable contains "hellojava" , i'd like the hellojava() method to be called..
if the string contains "error", the error() method should be called..
and so on..:)Here is an example I had thrown together for this
purpose of the exact demonstration, Ar'nt you in luck.:-). If there is anything you don't understand,
I can be reached at [email protected] and will be happy to help....
import java.lang.reflect.*;
import java.io.*;
class Test {
String name = "Default";
public Test(String name) {
this.name = name;
public void test() {
System.out.println("Hello");
public void count() {
for(int i=0; i<10; i++) {
System.out.println(i);
public static void main(String[] args) {
try {
Test myObject = new Test("test1");
Class myClass = myObject.getClass();
BufferedReader bRead =
new BufferedReader(
new InputStreamReader( System.in ));
String bufStr = null;
while( (bufStr = bRead.readLine()) != "exit") {
Method noParams = myClass.getDeclaredMethod(bufStr, new Class[] {});
noParams.invoke(myObject, new Object[] {});
}catch(Exception e) {
System.out.println("No Such Method.");
}Good Luck,
