Int ?
Hi!
I got this error, when using int, I believe that is the reason anyway,. Do i miss something there in the beginning?
Where on the net can I found which things is inluded in which "library"? (Like that i need javax.swing.*; for a dialogbox(JOptionPane)
Klas

import java.lang.Math;
import javax.swing.*;
public class uppg3_3{
E:\Program\Xinox Software\JCreator LE\MyProjects\uppg3_3.java:15: incompatible types
found : java.lang.String
required: int
ar=JOptionPane.showInputDialog("�r 1940-2002 :");
(ar is an int)
LE\MyProjects\uppg3_3.java:15: incompatible types
found : java.lang.String
required: int
ar=JOptionPane.showInputDialog("�r 1940-2002 :");
(ar is an int)JOptionPane.showInputDialog(String) returns a String, but your variable is an int. If you are expecting the input to be a number, then you must check that it is a number, and convert it accordingly. If you are absoloutely certain that the input is a number, then you can use
ar = Integer.parseInt(JOptionPane.showInputDialog("..."));

1. Get Report without data from the database
2. Change the dataconnections in report to the current user
3. refresh data on the report (FilePath = TempFilePath)
4. Resave report file with data
5. Automatically open CrystalReportsViewer2008 and load the report
Result
On developer machine is allright, but on the user machine data isn't refreshed. Therefore CrysrtalReportsViewer2008 can't open report. It say that check the SaveDatawithReport parameter.
In process I found that in temp directory on user pc, didn't creates some temprorary files which creates on developer PC. Why? Help me please.

How to get Int value from request.getParameter()?
Hi all,
I have a integer value which is passed from one page to another page.
i am geting this value in the next page using
request.getParameter().
Eg.
Suppose value of "i" in page1 is 32, i pass this as hidden variable to next page.
<input type="hidden" Value="<%=i%>" NAME="limit">
in page2, i fethch this value to a variable by name "limit"
String limit=request.getParameter("limit");
but, since value stored in limit is int, i can't assign it to string.
i can't use request.getParameter for int values.
How to solve my problem.
I know it is simple,
Pls. help me
Regards
ASh
String limit=request.getParameter("limit");String limitSTR = request.getParameter("limit");
int limit = -1;
if (limitSTR != null) limit = Integer.parseInt(limitSTR); -

Fields appear as "Read Only" in an Int.Form called from a WD
Hi Experts!
I am having a doubt in an Adobe Int.Form, that is called from a WD application.
The fields that are in my Form, always appear as a "read only". It is not possible to modify anything there.
Here, I describe the steps that I follow.
I create a very simple WD application. In its WD View, exist an unique Object (Adobe Interactive Form).
In that object, I set the properties:
"Data source": a context variable type "my structure". "My structure", is a simple structure with a couple or three fields, let´s say PERNR, BUKRS, WERKS... It is linked to the Form Interface (ABAP DICTIONARY-BASED INTERFACE). So in this way, the link between my WD and the AdobeInt.Form is working.
"PDF Source": a context variable type XSTRING.
"Template Source": here I have set my Int.Form. Currently, it only contains a couple of fields
"Enabled": True.
"Read Only": False.
In the AdobeForm, I have drag & droped those 2 or 3 fields, save it, and activate it. I guess nothing more is needed, for my test.
And at last, in the View´s method WDDOINIT, I am reading one of those fields, let´s say the employee number (PERNR), and I set by hardcoding its number (let´s say -> 00000001).
Until here, everything seems to work fine. When I launch the WD test, the Adobeform appears, at the moment, with only one of my fields (Employee - PERNR), and its value is filled in with '00000001'.
But now, I would like to write something by myself. And when I try to do it, it is not possible! Field PERNR, is displayed as a "READ ONLY".
Someone knows what is happening here? I guess it should be possible, to activate as a "EDITABLE" that field in my Form.
So here is my doubt.
Am I doing anything wrong? Or am I doing any mistake?
Thank you very much in advance!Finally I think I have found the problem.
In the View where I am printing the ADOBEFORM, it is needed this code under the method WDDOMODIFYVIEW.
method WDDOMODIFYVIEW .
DATA: LV_INTERACTIVE_FORM TYPE REF TO CL_WD_INTERACTIVE_FORM,
LV_METHOD_HANDLER TYPE REF TO IF_WD_IACTIVE_FORM_METHOD_HNDL.
LV_INTERACTIVE_FORM ?= VIEW->GET_ELEMENT( 'INT_FORM' ). " adobeform object in view
IF LV_INTERACTIVE_FORM IS NOT INITIAL.
LV_METHOD_HANDLER ?= LV_INTERACTIVE_FORM->_METHOD_HANDLER.
LV_METHOD_HANDLER->SET_LEGACY_EDITING_ENABLED( ABAP_TRUE ).

WD_THIS->M_METHOD_HANDLER ?= LV_INTERACTIVE_FORM->_METHOD_HANDLER.

ENDIF.

Can not cast from object to int
Hi All,
I have the following bunch of code
Session session;
session = getSessionFactory().openSession();
Query query;
int MaxPageId = 0;
List list;
try{
query = session.createQuery("select max(emp.id) from EmpBean emp");
list = query.list();
MaxPageId = (int) list.get(0);
return MaxPageId;
catch(Exception e){
System.out.println(e.getMessage());
return MaxPageId;
The query executed successfully but when i get the max id in a integer variable by the following statement
MaxPageId = (int) list.get(0);
I get the following error "can not cast from object to int"
Please suggest for the same.
-ThanksCast to an Integer, not an int, and let autoboxing turn the Integer into an int.
int maxPageId;
maxPageId = (Integer) list.get(0);You can't cast objects into primitives.
Autoboxing isn't casting.
And use Java naming conventions. Local variables start with a lower-case letter. -
Returning int array from C to Java as method parameter
Hello,
I've been trying to accomplish this
Java
int[] myArray = ... (filled with some data);
int retCode = myNativeCall(myArray);
if(retCode == 0)
doSomethingWith(myArray); //myArray gets overwritten with new data (with new size also) during the native call...
C
JNIEXPORT jint JNICALL Java_GenChav_rsaEncrypt(JNIEnv *env, jobject obj, jintArray myArray){
jintArray outbuf;
int[] new_array = .. // some function will fill this....
int new_array_length = ...//some function will give me the new size, not big, 512 max...
jint tmp[new_array_length]; //allocate..need something more ??
memcpy(tmp, new_array, new_array_lenght);
outbuf=(*env)->NewIntArray(env, new_array_length);
(*env)->SetIntArrayRegion(env, outbuf, 0, new_array_length, tmp);
myArray=outbuf;
I tought this way I would have a updated myArray ints on the Java program...
Any thought??user5945780 wrote:
Ok, let's try to be constructive here...
How I do implement a return type for my method like a int array ?First realized it has nothing to do with JNI. So the same question and answer applies to java only.
>
like:
int[] return = myNativeCall();
Yes.
Then I will look for return[0], if it is == to 0, fine, it means a successful calculation by the native code. Not sure what that means. The structure of what you return it up to you.
It can help when you are unsure of what to do in JNI....write a pseudo representation of what you want to do in a java method. Then translate that java method into JNI, everything in the pseudo method must be in the JNI code. -
SocketInputStream.read(byte[], int, int) extremely slow
Hi everyone,
I'm trying to send several commands to a server and for each command read one or more lines as response. To do that I'm using a good old Socket connection. I'm reading the response lines with BufferedReader.readLine, but it's very slow. VisualVM says, that SocketInputStream.read(byte[], int, int) is consuming most of the cpu time. A perl script, which does the same job, finishes in no time. So it's not a problem with the server.
I'm runnning java version "1.6.0_12"

Java HotSpot(TM) Server VM (build 11.2-b01, mixed mode) on Linux henni 2.6.25-gentoo-r7 #3 SMP PREEMPT Sat Jul 26 19:35:54 CEST 2008 i686 Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz GenuineIntel GNU/Linux and here's my code
private List<Response> readResponse() throws IOException {
List<Response> responses = new ArrayList<Response>();
String line = "";
while ( (line = in.readLine()) != null) {
int code = -1;
try {
code = Integer.parseInt(line.substring(0, 3));
line = line.substring(4);
} catch (Exception e) {
code = -1;
// TODO create different response objects ?!?
NotImplemented res = new NotImplemented(code, line);
responses.add(res);
// we received an "end of response" line and can stop reading from the socket
if(code >= 200 && code < 300) {
break;
return responses;
}Any hints are appreciated.

Exception in thread "main" java.lang.NullPointerException
at teamSelectorPanel.fillComboBox(TeamRosterAppTest.java:233)

I think I am not initializing something correctly and it involved the "team" variable. Thoughts anyone?
Thank you as always!

It removes CDs from anotherRack, but the rack I'm trying to fill in with anotherRack's CDs is filled with a one same CD from the anotherRack not various CDs as it should.. hard to explain.:)
Is some willing to give me tips? And is there some other way
to use insert method with the help of the move-method?

You still need to implement organize() and sortAlphabetically(), plus move the classes to their own files and modify the parameter names to match the assignment.
But, apart form that, here's what you wanted.
Now, I realy am going to ge those beers...

Null value for int and datetime date type in xml schema
hi:
I am embarrassed by a qustion in xml schema; i defined a xml schema file like
this:
<elementFormDefault="qualified" attributeFormDefault="qualified">
<xs:element name="test">
<xs:annotation>
<xs:documentation>Comment describing your root element</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="password" type="xs:string" nillable="true"/>
<xs:element name="user" type="xs:int" nillable="true"/>
<xs:element name="s_time" type="xs:dateTime"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
and I send this file to workflow clientrequest() node, I wanted to receive data
in this schema file.but when i send null value to the element "user" and "s_time"
in workshop test tool(test soap),and use function in xmlbean like isNilUser or
isNilStime, one error occur.
I don't kown why, I had to ask the engineer of bea in china, one told me a bug.
is that true?Visakh16 I cant agree more with you on it, it is good but in production u cant have them change maxrows. I think
Patrick Hurst is a better option. debug the package have it running and move up
Please mark as helpful and propose as answer if you find this as correct!!! Thanks,Dia Agha .
Hmm..Why do you need to change it in production?
What I suggested was to tweak the setting in dev machine so that it interprets the Excel file datatypes correctly when doing development. Once mapping is set correctly then it will work fine when in production or in any other environment. The tweaking is
just to make sure it interprets the datatype correctly at design time and has nothing to do with production deployment

Date from a string and int value in ssis
hi so my table is as follows
active expirymonth
expiryyear
0 October 2014
0 February 2015
1 January 2012
and so on
now my requirement is that if active =0 then in a new table lets say LASTDATE and they want a date with the last day of the expiry month and year and if active is anything else write NULL for eg
LASTDATE
10/31/2014
02/28/2015
NULL
I went to derived tables and made a new table called lastdate. What expression do i build in the expression builder to get the required result as i could not find a way to convert the text into int and then into a dateHi Bharatb111,
If you want to achieve this using Derived Columns transform, you have to use following expression to first convert the month name value to integer:
([expirymonth]==”January”)?1:([expirymonth]==“February”)?2: ([expirymonth]==”March”)?3:([expirymonth]==“April”)?4:5
However, if we need to validate a couple of or even all of twelve months, the expression validation will be failed. So, the Derived Column approach is impossible.
To achieve your goal, you can use a Script Component to perform the date format conversion. This way, we can convert “dd/MMMM/yyyy(such as “01/October/2014”) format string value to “MM/dd/yyyy” (such as “10/01/2014”), and assign this value to a new output
column (assuming its name is “DateVal” and its data type is DT_DATE) of the Script Component. Then, we can drag a Derived Column under the Script Component and connect them. In the Derived Column, we can add a new column named “LASTDATE” with the following
expression:
([active]==0)?DATEADD(“d”,-1, DATEADD(“Month”),1,DateVal]):NULL(DT_DATE)
For the Script Component code snippet, please refer to Reza’s answer:

Hope this helps.

i am trying to return the 'sportScore' int to a main quiz class but for some reason it hasnt worked...
can anyone tell me what i have done wrong?
thanks alot!this is my main quiz class:
import javax.swing.*;
public class Quiz
public static void main (String []args)
Object[] possibleValues = { "Sport", "Music", "General Knowledge", "TV and Film", "Display Score Board" };
Object choice;
do
choice = JOptionPane.showInputDialog(null,"Welcome to my quiz\nPlease select you category:", "selection", JOptionPane.YES_NO_CANCEL_OPTION, null,
possibleValues, possibleValues[0]);
if (choice.equals(JOptionPane.CANCEL_OPTION))
System.exit(0);
if (choice.equals(possibleValues[0]))
Sport.doQuiz();
if (choice.equals(possibleValues[1]))
Music.doQuiz();
if (choice.equals(possibleValues[2]))
General.doQuiz();
if (choice.equals(possibleValues[3]))
TV.doQuiz();
if (choice.equals(possibleValues[4]))
int sportScore = Sport.doQuiz();
int tvScore = TV.doQuiz();
int musicScore = Music.doQuiz();
int generalScore = General.doQuiz();
int totalScore = (sportScore+tvScore+musicScore+generalScore);
JOptionPane.showMessageDialog(null,"Thankyou for taking my quiz!\nhere are your results:\nSport: "
+ sportScore + "/3\nMusic: " + musicScore + "/3\nGeneral Knowledge: "
+ generalScore + "/3\nTV and Film: " + tvScore +"/3\n\nTOTAL: "
+ totalScore + "/12!");
while(!(choice.equals(possibleValues[4])));
}as you can see i have more than just the sport category but once i know how to do that one i will be able to do the rest...
now here is my sport class:
import javax.swing.*;
public class Sport
public static int doQuiz()
Object[] sportValues = { "Freddie", "jimbo", "the destroyer" };
Object sportq1;
Object[] sportValues2 = { "David Beckham", "Alessandro Del Piero",

Object sportq2;
Object[] sportValues3 = { "6", "10", "14" };
Object sportq3;
int sportScore = 0;
String message;
//............QUESTION 1..............
sportq1 = JOptionPane.showInputDialog(null, "Question 1: What nickname is given to england cricketer andrew flintoff?", "selection", JOptionPane.YES_NO_CANCEL_OPTION, null,
sportValues, sportValues[0]);
if (sportq1.equals(sportValues[0]))
message = "CORRECT!";
JOptionPane.showMessageDialog(null, message);
sportScore = (sportScore+1);
else
message = "WRONG!";
JOptionPane.showMessageDialog(null, message);
//............QUESTION 2.............
sportq2 = JOptionPane.showInputDialog(null, "Question 2: Who scored italy's second goal in the world cup final?", "selection", JOptionPane.YES_NO_CANCEL_OPTION, null,

sportValues3, sportValues3[0]);
if (sportq3.equals(sportValues3[0]))
message = "CORRECT!";
JOptionPane.showMessageDialog(null, message);
sportScore = (sportScore+1);
else
message = "WRONG!";
JOptionPane.showMessageDialog(null, message);
return sportScore;
}i am tring to return sportScore from the sport class to the main quiz class, at the moment instead of getting the sportScore at the end of the quiz class it is now running the whole sport class again!
what have i done wrong?

Convert byte array to table of int
[http://www.codeproject.com/KB/database/PassingArraysIntoSPs.aspx?display=Print|http://www.codeproject.com/KB/database/PassingArraysIntoSPs.aspx?display=Print] Hello friends.
I'm pretty new with PL/SQL.
I have code that run well on MSSQL and I want to convert it to PL/SQL with no luck.
The code converts byte array to table of int.
The byte array is actually array of int that was converted to bytes in C# for sending it as parameter.
The TSQL code is:
CREATE FUNCTION dbo.GetTableVarchar(@Data image)
RETURNS @DataTable TABLE (RowID int primary key IDENTITY ,
Value Varchar(8000))
AS
BEGIN
--First Test the data is of type Varchar.
IF(dbo.ValidateExpectedType(103, @Data)<>1) RETURN
--Loop thru the list inserting each
-- item into the variable table.
DECLARE @Ptr int, @Length int,
@VarcharLength smallint, @Value Varchar(8000)
SELECT @Length = DataLength(@Data), @Ptr = 2
WHILE(@Ptr<@Length)
BEGIN
--The first 2 bytes of each item is the length of the
--varchar, a negative number designates a null value.
SET @VarcharLength = SUBSTRING(@Data, @ptr, 2)
SET @Ptr = @Ptr + 2
IF(@VarcharLength<0)
SET @Value = NULL
ELSE
BEGIN
SET @Value = SUBSTRING(@Data, @ptr, @VarcharLength)
SET @Ptr = @Ptr + @VarcharLength
END
INSERT INTO @DataTable (Value) VALUES(@Value)
END
RETURN
END
It's taken from http://www.codeproject.com/KB/database/PassingArraysIntoSPs.aspx?display=Print.
The C# code is:
public byte[] Convert2Bytes(int[] list)
if (list == null || list.Length == 0)
return new byte[0];
byte[] data = new byte[list.Length * 4];
int k = 0;
for (int i = 0; i < list.Length; i++)
byte[] intBytes = BitConverter.GetBytes(list);
for (int j = intBytes.Length - 1; j >= 0; j--)
data[k++] = intBytes[j];
return data;
I tryied to convert the TSQL code to PL/SQL and thats what I've got:
FUNCTION GetTableInt(p_Data blob)
RETURN t_array --t_array is table of int
AS
l_Ptr number;
l_Length number;
l_ID number;
l_data t_array;
BEGIN
l_Length := dbms_lob.getlength(p_Data);
l_Ptr := 1;
WHILE(l_Ptr<=l_Length)
loop
l_ID := to_number( DBMS_LOB.SUBSTR (p_Data, 4, l_ptr));
IF(l_ID<-2147483646)THEN
IF(l_ID=-2147483648)THEN
l_ID := NULL;
ELSE
l_Ptr := l_Ptr + 4;
l_ID := to_number( DBMS_LOB.SUBSTR(p_Data, 4,l_ptr));
END IF;
END IF;
l_data(l_data.count) := l_ID;
l_Ptr := l_Ptr + 4;
END loop;
RETURN l_data;
END GetTableInt;
This isn't work.
This is the error:
Error report:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
06502. 00000 - "PL/SQL: numeric or value error%s"
I think the problem is in this line:
l_ID := to_number( DBMS_LOB.SUBSTR (p_Data, 4, l_ptr));
but I don't know how to fix that.
Thanks,
MTs.I'd found the solution.
I need to write:
l_ID := utl_raw.cast_to_binary_integer( DBMS_LOB.SUBSTR(p_Data, 4,l_ptr));
instead of:
l_ID := to_number( DBMS_LOB.SUBSTR (p_Data, 4, l_ptr));
The performance isn't good, it's take 2.8 sec to convert 5000 int, but it's works. -
Convert jstring to char array or int array
Hi all, please help with the following code. I've tested this code with hard coded char array and it works. Now I have to get the char array from parameter "param1" which is passed from Java.
The following code compiled with error message:
error C2223: left of '->GetStringUTFChars' must point to struct/union
JNIEXPORT void JNICALL Java_DongleSet_DongleWrite(JNIEnv *env,jobject obj,jstring param1){
char HaspBuffer[500]=(char)env->GetStringUTFChars(param1,NULL);
int Service=MEMOHASP_WRITEBLOCK;
int SeedCode=300;
int LptNum=0;
int Pass1=pass1;
int Pass2=pass2;
int p1=0;
int p2=12;
int p3=0;
int p4=(int)HaspBuffer;
hasp(Service,SeedCode,LptNum,Pass1,Pass2,&p1,&p2,&p3,&p4);
I've tried this:char HaspBuffer[500]=env->GetStringUTFChars(param1,NULL);
And this:char HaspBuffer[500]=(*env)->GetStringUTFChars(param1,NULL);
All give me errors.
Please help.char * HaspBuffer=(*env)->GetStringUTFChars(param1,NULL); When writing pure C, you have to supply the JNIEnv as first arg to every JNIEnv function pointer.char * HaspBuffer=(*env)->GetStringUTFChars(env, param1, NULL);Look here: http://developer.java.sun.com/developer/onlineTraining/Programming/JDCBook/jnistring.html
