clear your app. server logs ( or make copies of them if will you need them) and redo the whole process. check out the logs and you should see some reason for this. i do not know if Borland's logs will turn out helpful, but it did help me out in certain other situations.

Ajax call method which return json Data

Hi, I make one function , which i want to return json value , for this which return type i mention in function:
This is javascript which call Retrieve method.
<script>
debugger;
         var remoteDatasource = new kendo.data.DataSource({
             transport: {
                 read: {
type:"POST",
url: "Controllers/Home.cfc",
dataType: "json",
                     data: {
method: "Retrieve",
                         dataLists: JSON.stringify(request)
</script>
Home.cfc
component
remote   function Retrieve(string dataLists)
try
            q = new Query();
            q.setsql("SELECT * FROM Product");
            qResult = q.execute().getresult();
            col_len = ListLen(qResult.Columnlist);
            dataArray = ArrayNew(1);
            row = 0;
            col = 0;
            for(row = 1; row <= len; row++)
                 for(col = 1; col <= col_len; col++)
                      FieldName = ListGetAt(qResult.Columnlist, col);
                      dataArray[row][col] = qResult[FieldName][col];
      jsonvar=serializeJSON(dataArray);
catch(any e)
return jsonvar;

One can see immediately that you have to make the following corrections, at least:
Give the query a name;
Point the query to a datasource;
Define the variable 'len' (even better, use a different, less confusing, name for the variable).

Call methods (which are in the servlet) in my response page

Hello !
I want to call methods which are in the servlet ( its name is ServletRecap) BUT the call is made in the response page which is generated by the servlet ServletRecap !
I just want to allow the user to update his choice in the response page.
example: i choice A in the initial form but i change my mind and now i want to choice B in the response page : the choice have to be update in the database.
the insertion in the DB is made by a method in the servlet : so i have to recall the method in the response page!

I resume : how can I call a method in my servlet into my response page (in jsp).
the servlet generate this response page and i just want to update the choice of my user.
Thanks !!

I resume : how can I call a method in my servlet into my response page (in jsp).Don't do that. Put the message into a plain old Java class which can be called from both the servlet and the JSP.

Handling Methods which return Objects

I have a class called GenericObjectQueue, which essentially maintains a queue of objects.There is a method called getTopObject() which returns the first Object in the queue.
I use this class to maintain a queue "CustomerQ" of objects of the class "Customers ".Now when i write the following statements i get an error
customer firstcust= new customer();
firstcust= CustomerQ.getTopObject();
The compiler says incompatible types,
found : java.lang.Object
required: customer
How do I deal with this?
Thanks...RJ2

method called getTopObject() which returns the first
Object in the queue.Another way is to set the return type as 'Customer' in place of Object and return a Custome

Function or method which returns the full PDC path of webdynpro iview

Hi All,
I have created a webdynpro application and created a webdynpro Iview in portal and attached this view to a role. I am looking for any standard function module or method which returns the full PCD path of the webdynpro iview, when it executed from portal.
Regards,
H.K.Hayath Basha.

Well in ABAP, we don't have portal APIs to access potal catalog info.
The only available Portal Interface is IF_WD_PORTAL_INTEGRATION

Defining enum with abstract method which returns a generic type

Is it possible to define an abstract method which returns an geneic type like below? Thanks
public enum Type{
     A{
          public List<Integer> getData(){}
     B{
          public Set<String> getData{}
     abstract<T> T getData();
}

vulee wrote:
Why not?
List<Integer> lst = Type.A.getData();Wonder, which compiler you use. Can't be Java6:
# javac Enums.java
Enums.java:23: incompatible types
found   : java.util.Collection<capture#376 of ?>
required: java.util.List<java.lang.Integer>
                List<Integer> data = Type.A.getData();
                                                   ^
1 errorEdit: Unless you do it the generic way as you proposed, which actually is a phoney. Because of the T being a generic method parameter, the compiler will infer it from the type of the variable it gets assigned to. Hence, both of the following will compile:
List<Integer> lst = Type.A.getData();
Set<String> lst2 = Type.A.getData(); // Runtime exceptionActually, javac is telling you that giving warnings on the enum constants redefined method return types.

Looping over method which returns a query

HI,
I have a method that returns a query, I pass into this method
a ID number, which the query uses in the where clause. Now I have
another query which returns a list of ID numbers that I loop
through calling the first method and passing in the ID number, for
example
methodA
loop through methodA results
call methodB passing in methodA.ID
get results from methodB
close loop
now the problem I'm having is that methodB returns a query
and I want to be able to return the results from methodB as one
single query structure. I'm not sure how many times I will loop
through the results from methodA, it could be twice, it could by
ten time. So the results from calling methodB could be very large.
How can I add the results from methodB into one single query
structure?

how about creating an empty query with cfset newQuery =
QueryNew([list of columns]);
and then on each loop through method B add a new row to this
new query, and then return that query as result?

Android Lync Mobile client authentication method

Good day dears,
I'm very interested in using passive authentication which is really an excellent method ,
and I wonder when will Andriod Lync Mobile client 2013 will support this method ?
or if there is any similar method that can be used currently
Regards.
Best Regards Bisher Shbib

Currently the passive authentication is not applied to Lync android client.

Method foo() must include java.rmi.RemoteException

Here's the full exception:
In EJB VWBaseUser, method setUsername(java.lang.String) defined in the remote
interface must include java.rmi.RemoteException in its throws clause.
The problem is, I am throwing RemoteExceptions in my remote interface! Here's
the code:
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface VWBaseUser extends EJBObject
public String getFirstName() throws java.rmi.RemoteException;
public void setFirstName() throws java.rmi.RemoteException;
public String getLastName() throws java.rmi.RemoteException;
public void setLastName() throws java.rmi.RemoteException;
public String getUserName() throws java.rmi.RemoteException;
public void setUserName() throws java.rmi.RemoteException;
public String getPassword() throws java.rmi.RemoteException;
public void setPassword() throws java.rmi.RemoteException;
What gives?!? The only thing I could think of was that I'm somehow using an old
JDK to compile with, but I thought I checked that and it was pointing to JDK 1.3.1
(unfortunately, we're still using VisualCafe, and an old version at that, since
Webgain is imploding)

Yup, that must've been it. I did have the classes elsewhere in 'exploded' format,
in addition to my EJB jar. Got rid of them, and the problem went away.
Thanks!

The usual cause is you have another version of this class in your
classpath which doesn't contain the RemoteException, and ejbc is finding
this version.

How do I deal with a Java method which returns a class object?

Hi, I am using JNI to talk to some Java code from c++;
I have a java method in class B that is defined as
class B{
A[] As;
A getA(int i){
return As(i);
where A is one of my classes.
I would like to know the code to deal with a returned object of type A and then how to access the variables in A from c++.
I have defined my method pointer as :
env->GetMethodID(B, "getA", "(I)A;");and have the jclass object of type A.
Would I do something like jclass A_CLASS = env->FindClass("A");
jobject A_OBJECT = (A_CLASS)env->CallObjectMethod(B,getA, i) ; If so, how do I then access the fields in A_OBJECT? Please let me know, thanks.

Thanks but this doesn't really help. I know how this is done in Java (see below).Presumably you also understand how that code will fail. At least based on what you have posted here.
I do not understand the syntax to do the equivalent thing in JNI, specifically, how to cast the returned object from the CallObjectMethod function to be of the appropriate type, namely A, and then how to access those fields. You don't cast it. Didn't do so in your java code either.
But you define how you are going to attempt to access any object in JNI. If you mess up it fails.

How to call function which return and out

My function specifcation is
FUNCTION GetGoogleScholarActivation (
pi_clnt_id IN google_scholar_status.clnt_id%TYPE,
pi_status_type IN ci_status_type_tab_type,
po_status OUT ci_status_tab_type,
po_date OUT ci_date_tab_type
RETURN NUMBER ;
where type is
TYPE ci_status_type_tab_type IS TABLE OF VARCHAR2 (1) INDEX BY BINARY_INTEGER;
TYPE ci_status_tab_type IS TABLE OF VARCHAR2 (10) INDEX BY BINARY_INTEGER;
TYPE ci_date_tab_type IS TABLE OF VARCHAR2 (8) INDEX BY BINARY_INTEGER;
I am trying to call function in SQL PLUS for testing as
declare
var number ( 10);
TYPE p_st1 IS TABLE OF VARCHAR2 (1) INDEX BY BINARY_INTEGER;
p_st p_st1 ;
type p_status1 IS TABLE OF VARCHAR2 (1) INDEX BY BINARY_INTEGER;
p_status p_status1 ;
TYPE p_date1 IS TABLE OF VARCHAR2 (8) INDEX BY BINARY_INTEGER;
p_date p_date1 ;
Begin
p_st(0) := 'A';
var := PQDKGOSH.GetGoogleScholarActivation(11920 , p_st, p_status ,p_date );
dbms_output.put_line ('Activation_status '|| p_status(0) );
dbms_output.put_line ('Activation_date '|| p_date(0) );
dbms_output.put_line ('Retun Value'|| var );
End;
but getting error PLS-00306: wrong number or types of arguments in call to
'GETGOOGLESCHOLARACTIVATION'
so how to test from SQL Plus

HI
I tried to execute below like this
declare
var number ( 10);
p_st ci_status_type_tab_type ;
p_status ci_status_tab_type;
p_date ci_date_tab_type;

dbms_output.put_line ('Activation_date '|| p_date(0) );
dbms_output.put_line ('Retun Value'|| var );
End;
still iget error
PLS-00201: identifier 'CI_STATUS_TYPE_TAB_TYPE' must be declared
becuse this declareation i did in package specification .
and i am trying to execute the function .

Calling a method that returns an object Array

Hello.
During a JNICALL , I wish to call a method which returns an object array.
ie my java class has a method of the form
public MyObject[] getSomeObjects(String aString){
MyObject[] theObjects=new MyObject[10];
return theObjects
Is there an equivalent to (env)->CallObjectMethod(...
which returns a jobjectArray instead of a jobject, and if not could somebody suggest a way around this.
Thanks,
Neil

I believe an array oj jobjects is also a jobject. You can then cast it to another class.

Calling from javascript a method which uses accesscontroller.dopriviledged

Hello everybody!
I've a problem in accessing my pc resources from a signed applet when calling methods from Javascript.
If I try from start() or init() methods, I can do it, but as soon as I try from anoter method defined by myself, it throws this me an AccessControlException:access denied.
I googled and found that I should use this code:
KeyStore smartCardKeyStore= (KeyStore)
             AccessController.doPrivileged(
                       new PrivilegedExceptionAction() {
                         public Object run() throws KeyStoreException, NoSuchProviderException, NoSuchAlgorithmException, CertificateException, IOException {
                             KeyStore alfa;
                             alfa = KeyStore.getInstance("PKCS11",pkcs11Provider.getName());
                             alfa.load(null,null);//this is the point where it trhew the AccessControlException
                             return alfa;
                     );The problem is that with this code, I can't get it work with Firefox (which doesn't throw any exception, just won't work!) neither with IE, which throws this:
netscape.javascript.JSException: Nome sconosciuto.
java.lang.Exception: netscape.javascript.JSException: Nome sconosciuto.

Thank you in advance! :)

Hi! Don,
You cannot call methods which breach Security from Javascript. That is what SUN says.
But there is a hack, or a work around...
Declare a boolean Variable , say named buttonClicked.
Initailly keep its value false(default).
Write an inner class that extends a thread class whose RUN method will contain the following piece of Code:
public void run(){
    while(buttonClicked){
                 KeyStore smartCardKeyStore= (KeyStore)
             AccessController.doPrivileged(
                       new PrivilegedExceptionAction() {
                         public Object run() throws KeyStoreException, NoSuchProviderException, NoSuchAlgorithmException, CertificateException, IOException {
                             KeyStore alfa;
                             alfa = KeyStore.getInstance("PKCS11",pkcs11Provider.getName());
                             alfa.load(null,null);//this is the point where it trhew the AccessControlException
                             return alfa;
}You start the Thread inner class in your init method.
So, its RUN method will continuously be waiting to go into the while loop.
And in your start method you will set the +"buttonClicked"+ variable to true upon a Javascript onclick event of a button.
So, the moment you click a button, you only set the buttonClciked variable to true in your start method--------
This does, in no way breach security. So no exception is thrown.. But the code which breaches security is initiated by another thread other than that spawned the Applet; so the browser does not care anything about its privileges. It just lets the execution of the code.
I hope it works for you; be in contact, if it doesn't.
Thanks and Regards,
Samba
