Returned array from a method don't work properly over my Servlet

Hi folks,
I show you my code and then explain ;).
        double particle_sys[] = new double[100*5];
     double particle[];
try {
         for(i = 0; i < 10; i++)
          particle_sys[i*5] = 1;
          particle_sys[i*5 + 1] = 0;
          particle_sys[i*5 + 2] = 1;
          particle_sys[i*5 + 3] = 0;
          particle_sys[i*5 + 4] = 0;
     class call = new class();
     particle = call.MyFailingMethod(particle_sys);Now the code for the class which owns the method I call
public class Jfjni
     static
             System.loadLibrary("nativelibrary");
     public native void .........
     public double[] MyFailingMethod(double particle_sys[])
           double particle[] = new double[100*5];
           .... A call to a the native library to recibe the new data of particle_sys ....
         for(int i = 0; i < 10; i++)
          particle[i*5] = particle_sys[i*5];
          particle[i*5 + 1] = particle_sys[i*5 + 1];
          particle[i*5 + 2] = particle_sys[i*5 + 2];
          particle[i*5 + 3] = particle_sys[i*5 + 3];
          particle[i*5 + 4] = particle_sys[i*5 + 4];
          return particle;
}A function in the native code changes the "particle_sys" array, but the returning value stills the same as the original passed to the function.
Because of this, I have tested returning the array, dont works. I have tested also returning a copy of the array in "particle", dont works.
Over standalone app and applet it runs correctly in all different ways, when I try it over a servlet the values of the array stand the same as before the method call.
Please suggestions!

I have partially solutioned this mistake but I have collateral ones. Looks like I forgot to put in web.xml the definition of the class I was calling from the principal servlet class. In other words, I have two classes, one is the extension of Httpservlet and the other (the class that make mistakes) is a class I call to do the JNI work.
Now, I added in web.xml the definition of the JNI class (before I forgot) and looks the mistakes with arrays works, but know the there's a new problem and get an IOexception on the applet that call the servlet. When I coment the JNI calls the exception dissapears and all works ok, but I am not getting any exception report on the tomcat ".out".
Please suggestions.

How to get the returned value from Functions with Callable statement?

I was glad to find that stored procedures can be invoke with Java class code by the object of Callable statement like :
String stmt = "BEGIN departments_pkg.do_select(?,?,?); END;";
and getting the output variables by
populateAttribute(DEPARTMENTNAME,st.getString(2),true,false);
But i would like to get values returned from FUNCTION other than stored procedure, how can i achieve it? Thanks a lot!

Here is my code
PROCESS BEFORE OUTPUT.
MODULE STATUS_1202.
MODULE subscreen_find.
CALL SUBSCREEN SUBSEARCH INCLUDING sy-cprog dynnr.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_1202.
CALL SUBSCREEN SUBSEARCH.
MODULE subscreen_find.
case sy-ucomm.
    when 'SELECTED'.             "fcode
      case 'ZSKILL_SEARCH'.     "data element
        when '01'.                       " value range
          dynnr = 0110.
        when '02'.
          dynnr = 0111.
      endcase.
endcase.
ENDMODULE.
kindly tell me what is wrong

Need help on returning arrays from C++ to Java

Hi all, I hava a C++ application that contains a method that will return a float array to Java. I was able to write the Java Code, the JNI code to call the C++ method and compile them successfully. However on calling the native method from Java, the data in the array returned was not what I want. Please look through my code and see what is wrong with it.
My Java Code:
public native float[] Statistics(int inputKey); // This is the native method
public float[] Stats(int k){ //Java method to call the native method so that I can use it in a Bean for a JSP.
inputKey = k;
float[] p = new float[4];
p = Statistics(inputKey);
return p;
For this native method, an integer is passed from Java to the native side and the native method will use this integer to generate a float array size of 4 and populate it with data and return it back to Java.
My JNI code
extern "C"
JNIEXPORT jfloatArray JNICALL
Java_com_jspsmart_upload_FinalWaterMark_Statistics(JNIEnv *env, jobject obj, jint inputKey)
     jfloatArray floatArray = env->NewFloatArray(4); //This creates a new Java floatArray to store the C++ array
     CWatermarker2App p; // This is the C++ class to be used
     jfloat *stats = p.OnWatermarkStatistics(inputKey) // The C++ method returns a float pointer for an array of size 4
     env->SetFloatArrayRegion(floatArray, 0 , 4 , stats); //storing the C++ float array into the Java float Array
     return floatArray; // return the Array to Java
In this example, I should have the data returned as [4952.0 2529.0 1706.0 33.6] in the array.
But i am getting junk instead like 2.53E-23, 1.402E-15 etc..
Is this a type conversion mistake?
Please help!

The first thing I notice - probably not the problem - is the line defining p. There is no reason to define this as an array of size 4, because the return from the native method is going to wipe that definition, replacing it with the return value of the native method. Alternatives:
1. float[] p = null.
2. float[] p = Statistics(inputKey);
3. return Statistics(k);

Return value from function within package

Hi,
There is a function within a pl/sql package that I am trying to get data from. The problem is that the data returned can be up to 32,767 chars (varchar2 limit).
It accepts 3 input parameters and returns on varchar2.
The only way I can get it to work is using this syntax:
==================================
variable hold varchar2(4000);
call TrigCodeGenerator.GenerateCode(VALUE1', 'VALUE2','VALUE3') into :hold;
print hold;
=====================================
However, if the data returned is greater than 4000 then I get this error:
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 1
I can't increase the size of the variable (hold) as there seems to be a limitation on this type of variable.
Also, I am running this in sql plus worksheet. Will it limit the display of the data (assuming, that someone can get the whole 32,767 chars displayed back) ?
Thanks in advance,
Ned

Never mind,
I declared the variable hold as clob and set the long and longchunksize parameters to 100,000 and it seems to work.

Error getting return value from function

Hello
I'm getting a error calling a function with ODP.NET from C#
Code:
OracleCommand oraCom = new OracleCommand("NORMALIZACION.nif",oraCon);
oraCom.CommandType = CommandType.StoredProcedure;
OracleParameter param1 = new OracleParameter("numnif",OracleDbType.Varchar2);
param1.Value= "73667866A";
param1.Direction = ParameterDirection.Input;
OracleParameter param2 = new OracleParameter("nif",OracleDbType.Varchar2);
param2.Size = 10; //FIXME line
param2.Direction = ParameterDirection.ReturnValue;
oraCom.Parameters.Add(param1);
oraCom.Parameters.Add(param2);
oraCom.ExecuteNonQuery();
nif_norm = oraCom.Parameters["nif"].Value.ToString();
if i write the FIXME line i get a error (ORA-06502) complaining about the size, no matter the value i wrote.
If i don't write the FIXME line, it works but nif_norm is always empty, although the function i call is a single return 'Hello';
Where am I wrong??
Any help, examples with varchar2 as return value???
BTW: the same code with the MS provider for Oracle works fine.

Good point -- i shall do so.
What I think I'm missing, in my quest for ODP.NET competence, is a solid set of example code. I've searched around and found various fragements here and there, but when it comes to data access from .NET there must surely be some finitie set of possibilities (if we can discount bad practices like building dynamic SQL statements without bind variables).
For example, possibly in increasing order of complexity ...
* Read a single value from a SQL statement ... "select emp_name from emp where rownum < 2"
* Read a single value by passing in a parameter ... "select emp_name from emp where user_id = :?"
* read multiple values ... "select emp_name from emp where user_id in (:?,:?)"
* execute a stored procedure with no in or out parameters
* retreive a value from a function with no parameters
* pass a parameter to a stored procedure
* read an out parameter from a stored procedure
Then work with in and out ref cursors, blobs, whatever.
Thoughts?

Return Vector from function and print it out.

Hey guys, I am not sure I'm doing this right. I have a class that currently has one function "getVector". This takes a string that is input and turns into a Vector array and returns the array as Vector.
Then in the second class I simply want to print out the Vector. I get no errors, but it doesn't print anything.
If anyone can see what I am doing wrong I'd appreciate the help.
Thanks!
Here is the first class that has the getVector function
import java.util.*;
public class GetArrays {
    public Vector getVector (String s){
        Vector theVector = new Vector();
        StringTokenizer token=new StringTokenizer(s," ");
            while (token.hasMoreTokens()){
                String tk=token.nextToken();// get each token
                theVector.add(tk);
             }// end while
        return theVector;
    }//end getVector
}//end classAnd here is the class with main that tries to print it out.
import java.util.*;
public class ShowArrays {
    public static void main(String[] args) {
        ShowArrays showArrays = new ShowArrays();
        Vector theArray = new Vector();
        GetArrays getArrays = new GetArrays();
        theArray = getArrays.getVector("testing this function");
        ListIterator iterator = theArray.listIterator(theArray.size());
        while(iterator.hasNext()){
            System.out.println(iterator.next()+"\n");
          }// end while
    }//end main
}//end class

Remove the parameter to your call to. Adding this parameter starts the iterator at the element theArray.size(), which is the end of the array.
ListIterator iterator = theArray.listIterator();

Returning Cursor from Function

I have been struggling all afternoon to get a package function
to return a cursor. Following some advice from the forums, I
think I'm getting close. <vbg> But am getting a compile error
on my RETURN statement. Can someone please help or post a
working example of how to do this. Thanks!
-- IN PACKAGE HEADER
type package_cursor is ref cursor;
function testfunction (p_system_date in date)
return package_cursor;
-- IN PACKAGE BODY
function testfunction (p_system_date in date)
return package_cursor is
cursor c1 is
select columns from tables where mydate = p_system_date;
begin
open c1;
return c1;
end testfunction;

Nevermind, I figured it out by using Barbara Boehmer example in
the "function returning record or table" thread.
function testfunction (
p_system_date in date)
return package_cursor is
vret package_cursor;
begin
open vret for
select columns from tables where mydate = p_system_date;
return vret;
end testfunction;

Returning arrays from methods

Hello,
I'm trying to write a program that is structured like this;
- The first method gets the user to enter 20 integers, which are stored in an array.
- This method is then supposed to return this array.
- The main method calls the first method (the one with the array).
- The main method then calls another method which finds the highest value in the array passed to it (from the initial method) and then prints this value.
I've tried for about 2 hours now though, and can't get it to return the array.
Bear in mind I'm a novice at Java. I'll put my code below. Any help on this would be really appreciated because I'm totally stumped.
public class part1
     static int counter=20;
     public static void enterMarks()
               int classMarks[] = new int[20];
               for (int i=0; i<20; i++)
                         classMarks[i] = getScannerInput.anInt("Please enter an integer value between 0 and 20 for each mark :");
                         System.out.println();
                         System.out.print("The marks entered were ");
                         for (int j=0; j<counter; j++)
                                   System.out.print(classMarks[j]+", ");
     public static void max()
//               int[] classMarks2=classMarks;
     public static void main(String args[])
               int[] marks=enterMarks();
}Can someone tell me how I need to alter this so that the first method will return the array? Thanks in advance.

Thanks for all the help so far everyone, I'm finally getting somewhere, but I've another problem. Here's my current code:
     static int counter=20;
     public static int[] enterMarks()
               int classMarks[]= new int[counter];
               for (int i=0; i<counter; i++)
                         classMarks[i] = getScannerInput.anInt("Please enter an integer value between 0 and 20 for each mark :");
                         System.out.println();
                         System.out.print("The marks entered were ");
                         for (int j=0; j<counter; j++)
                                   System.out.print(classMarks[j]+", ");
                              return classMarks;
     public static int max(int arr[])
               int[] marks = classMarks;
               int tempStore=0;
               for (int k=0;k<counter;k++)
                    if(marks[k]>marks[k+1])
                    tempStore=marks[k];
               return tempStore;
     public static void main(String args[])
               int[] marks = enterMarks();
}When I try to compile that, I'm told that the variable classMarks may not have been initialised. Surely it should be getting classMarks from the first method now that the first method is set up to return the array?

Returning objects from functions

Hi,
public HSSFRow someFunction() {
   HSSFRow returnrow;
   Iterator rowiterator = someobject.rowIterator();
      while(rowiterator.hasNext()) {
         returnrow = rowiterator.next();
   return returnrow;
}My problem is this, I want to pass a HSSFRow object back from a function, but the constructor to this object is protected so i cant initialize an object, this code wont compile because it says that the returnrow object might not have been initialized. How do i get round this problem?

Hey-
You could just initialize returnrow to null and check for null whenever you call someFunction(), that should do it.

Returning Recordsets from Functions

Pardon my ignorance; there is probably a simple answer to this one, but I'm trying to make the leap to Oracle Stored Procedures and I have a basic question:
I have created a Function in Oracle 8.1.7 EMP_SEL_ALL, based on the following SQL Statement:
CREATE OR REPLACE FUNCTION "SCOTT"."EMP_SEL_ALL" (
          enuma          IN NUMBER)
          RETURN SCOTT.emp%ROWTYPE IS
emp_row SCOTT.emp%ROWTYPE;
BEGIN
     SELECT * into emp_row FROM SCOTT.emp
     WHERE empno = enuma;
RETURN emp_row;
END;
The function compiles with no problems.
I have written a Java call to execute the Function, which reads as follows. Because I am attempting to return an entire row, I assume that will equate to a ResultSet:
sqlCallStmt = con.prepareCall("{ call SCOTT.EMP_SEL_ALL ? ) }");
sqlCallStmt.setInt(1, 7369);
result = sqlCallStmt.executeQuery();
The error returned is as follows:
java.sql.SQLException: ORA-06550: line 1, column 7:
PLS-00221: 'EMP_SEL_ALL' is not a procedure or is undefined
Looking in DBA Studio, the Function is shown in the SCOTT schema, and I am logged in as that user. I am therefore inclined to think that, rather than a permissions issue, I have a syntax error somewhere, or I have left out a step.
For anyone who has been down this road before, please advise. Is there a better way to do this via Stored Procedure? I have no problem querying the table and data in a standard SQL statement. Many thanks in advance.

First, when you call a function I think you have to use the syntax {call ? = function_name} (notice where the ? goes.
However, I still don't think you will be able to get this to work becuase a Java client cannot interpret a PL/SQL record (or rowtype, in your case).
If you want to return the results as a recordset, you will have to move the function into package and declare a REF CURSOR for the return type. It appears your code only returns one row, however, so a recordset will create unnecessary overhead.
It would probably be best to make your function a procedure that returns OUT parameters, one for each column selected.

Return variable from Function

I have a function that if I write-host the variable $RDPUser from within the function it returns true, however I can't seem to get the variable to be seen outside the function, even if I make it global
Function global:RDP (){
$WorkstationName = Get-Content env:ComputerName
    # Run the qwinsta.exe and parse the output
    $queryResults = (qwinsta /server:$WorkstationName | foreach { (($_.trim() -replace "\s+",","))} | ConvertFrom-Csv)
    # Pull the session information from each instance
    ForEach ($queryResult in $queryResults) {
        $RDPUser = $queryResult.USERNAME
        $sessionType = $queryResult.SESSIONNAME
        # We only want to display where a "person" is logged in. Otherwise unused sessions show up as USERNAME as a number
        If (($RDPUser -match "[a-z]") -and ($RDPUser -ne $NULL)) {
            # When running interactively, uncomment the Write-Host line below to show the output to screen
             $LoggedOnUser = $RDPUser
         $RDPHost
            #$SessionList = $SessionList + "`n`n" + $ServerName + " logged in by " + $RDPUser + " on " + $sessionType
#Get Current Time
$time2 = Get-Date
#Get Logged-On User Details
$user = Get-WmiObject Win32_Computersystem -ComputerName "."
#Get Time User Logged On
$time1 = Get-EventLog -LogName System -InstanceId 7001 -Newest 1
#Set Variables for SQL
$LogonDateTime = get-date -Format "MMM dd yyyy HH:mm:ss"
$WorkstationName = Get-Content env:ComputerName
$LoggedOnUser = $user.UserName
$TimeToLogon = $time2.TimeOfDay.TotalSeconds - $time1.TimeGenerated.TimeOfDay.TotalSeconds
$logonType = "Logon"
#If workstation = QATest Set $result
if ($workstationName -eq "QAtest") {$result = RDP ; $LoggedOnUser = $result}
write-host $LogonDateTime
write-host $WorkstationName
write-host $LoggedOnUser
write-host $TimeToLogon
write-host $logonType
Alter De Ruine

For some reason I needed my If statement inside the function:
Function RDP (){

How to Return Type from Function

I've defined a type and a function in specification. But package body returns pls-00330 error (invalid use of type name or subtype name). What am I doing wrong? My intent is to write a function which will return a record containing two values. For now, I put "null;" as a placeholder.
--specification
CREATE OR REPLACE PACKAGE res.year_qtr AS
TYPE yq_type IS RECORD
(yr varchar2(2),
qtr varchar2(1));
FUNCTION yq_fun (date_in date)
RETURN yq_type;
END year_qtr;
-body
CREATE OR REPLACE PACKAGE BODY res.year_qtr AS
FUNCTION yq_fun (date_in date)
RETURN yq_type IS
BEGIN
null;
RETURN year_qtr.yq_type; --get error on this line!
END;
END year_qtr;

You need to declare a variable of that type and return the variable.
You can't just return the type as it's not actually a declaration of that type.
--specification
CREATE OR REPLACE PACKAGE res.year_qtr AS
TYPE yq_type IS RECORD
    (yr varchar2(2),
     qtr varchar2(1));
FUNCTION yq_fun (date_in date)
    RETURN yq_type;
END year_qtr;
--body
CREATE OR REPLACE PACKAGE BODY res.year_qtr AS
FUNCTION yq_fun (date_in date) RETURN yq_type IS
    v_ret year_qtr.yq_type;
BEGIN
    null;
    RETURN v_ret;
END;
END year_qtr;
