JNI - Passing an object containing an array field

I need to pass an object to a native method. The object contains several int fields and a field that is an int array (contains 32 int).
I have no problem with the int fields, but do not know how to access the int array field in the C code. What approach should be used to get/set values in the int array field?
Any suggestions are appreciated.

I have been reading up on the subject, but I guess I'm just an idiot. If all the answers were obvious from reading the specification then there wouldn't be much point to this forum.
For int fields in the object passed to the native function I do the following to set the value:
fid = (*env)->GetFieldID(env, cls, "intFieldName", "I");
(*env)->SetIntField(env, myObj, fid, newValue);
For a field that is an array of int, it seems that I can get the field ID as follows:
fid = (*env)->GetFieldID(env, cls, "arrayFieldName", "[I");
The "Get<Type>Field" and "Set<Type>Field" methods can be used for object, boolean, byte, char, short, int, long, float, double. Nothing specific here for array. Should I use the GetObjectField method, if so can the object field then be handled as an array? This is where I am missing something. I have experimented with using the SetIntArrayRegion method but this causes an exception - obviously missing a necessary step here. I am hoping someone here can provide guidance on what I am missing, what JNI functions I should be using, or refer me to the appropriate page of the specification or other document where it is explained (for idiots like me).

Hi,
You can use the follwing
in USR12 table
in USOBT table (but you get the details for the Auth Obj in the Tcodes and their field values.
But as far as my knowledge goes you will get all the Auth Obj with Company code field
Caution: If there are some objects in not check or are which are not in any tcodes then they will not be captured.
But they are very less I guess and so i think you can capture most of the Auth Obj I guess

Please tell me how I can set an array field to an object?

Hi,
Please tell me how I can set the plID (an array field) to an object? This result is for one Agent object. Suppose the Agent object only has these two fields.
If a sql query result is something like this (which is one object).
agent_last PLID
smith      5
smith               6
smith               7
Agent agent = new Agent();
StringBuffer sql = new StringBuffer();
int count = getPLNo(agentID);// # of the query result
try {
SQL tsql = new SQL();
Connection conn = tsql.getConnection();
sql.append("SELECT agent_last, b.PLID ");
sql.append("FROM Agent a, PL b ");
sql.append("where a.agent_id = b.agent_id ");
sql.append("and a.agent_id = ? ");
PreparedStatement st = conn.prepareStatement(sql.toString());
st.setInt(1, agentID);
ResultSet rs = st.executeQuery();
while (rs.next()) {
agent.setAgentID(agentID);
agent.setAgentLast(rs.getString(1));
for ( int i = 0 ; i < count; i++ ) {               //how to do it?
agent.setPrivateLabelID(new int[] {rs.getInt(2)});//how to do it?
st.close();
rs.close();
tsql.close();
} catch (SQLException e) {
System.out.println("SQL: " + e.getMessage());
throw new Exception(e.getMessage());
} catch (Exception e) {
System.out.println("Except: " + e.getMessage());
throw new Exception(e.getMessage());
return agent;
}

If that's not what you're looking for, then you get
what you pay for. :-)Hi fmeyer75,
Thank you very much for your input. That's exactly what I was looking for and it works!!!!
For anyone who has similar issue, I changed the code a little to make it work with my existing ones. I never splited queries before, so please tell me if there's a better way to handle it.
I keep the first half part and changed a little for the second half. Below is what I use now
sql.setLength(0);
sql.append("SELECT PLID ");
sql.append("FROM PL ");
sql.append("where agent_id = ? ");
List list = new ArrayList();
PreparedStatement st2 = conn.prepareStatement(sql.toString());
st2.setInt(1, agentID);
ResultSet rs2 = st2.executeQuery();
while (rs2.next()) {
             list.add(new Integer(rs2.getInt(1)));
agent.setPrivateLabelID(new int[list.size()]) ;
for ( int i = 0 ; i < list.size(); i++ ) {
agent.getPrivateLabelID() = ((Integer)
list.get(i)).intValue() ;
st.close();
rs.close();
st2.close();
rs2.close();

How can I pass a docking container to a program in a non-simple context?

Dear colleagues,
I want to pass a docking container like the one in SE80 to another program.
The following code works fine:
REPORT z_moving_dock.
DATA: cl_docker type REF TO cl_gui_docking_container.
PARAMETERS: test.
INITIALIZATION.
CREATE OBJECT cl_docker EXPORTING no_autodef_progid_dynnr = 'X'.
END-OF-SELECTION.
WRITE:/ test.
But I cannot extend this to my current program. There I sourced out anything related to the GUI into a function group to obey the MVC paradigma. (That's maybe the error in reasoning, but I'm following the book Design Patterns in Object-Oriented ABAP from SAP Press and -- of course -- good and healthy programming style.)
So it's a function group which knows the dynpros and controls, the main program knows only the data.
Now I have a docking container like the one in SE80. We have many working older programs and I want to switch to them carrying the docking container with me. I have searched the Demos in SAP, the Online Help, the SAP Library, Books, the Web, this Forum, but none of them goes beyond the simpler examples that always work.
I tried the LINK method on the docking container. I tried it before calling the new program (btw. by SUBMIT). I tried it afterwards from the called program (via a function module from the aforementioned group -- but the group is tied to the old program context and therefore I am in a new "instance" of it). I tried different values for REPID and DYNNR in LINK. I debugged SE80 -- too complicated!
If it works well I get the container back when I return to the calling program. If it works badly the container is completely lost.
Perhaps I should export something to memory?
But I strongly would prefer not to alter the called programs: In the future I might also want to call a SAP standard program.
I also didn't find some documentation explaining what is going on in the background so I could figure out in which direction to "think".
I also tested the following code on SAP R/3 4.7 and SAP ERP 2005 with the same results.
In the meantime I also created a minimal example. First the triggering report:
REPORT z_moving_docking_container.
DATA: g_example TYPE REF TO zcl_moving_docking_container.
CREATE OBJECT g_example.
This obviously calls the main class ZCL_MOVING_DOCKING_CONTAINER which has only this constructor:
METHOD constructor.
CALL FUNCTION 'Z_SHOW_DYNPRO'.
ENDMETHOD.
Normally this class should handle the business logic. Here it only calls this function module. In the appropriate function group, say Z_MOVING_DOCKING_CONTAINER, I have these declarations in the TOP-Include:
FUNCTION-POOL z_moving_docking_container.
DATA:
gv_okcode TYPE ui_func,
go_docker TYPE REF TO cl_gui_docking_container.
The function group also contains a dynpro 9000 with this flow logic:
PROCESS BEFORE OUTPUT.
MODULE status_9000.
PROCESS AFTER INPUT.
MODULE user_command_9000.
The modules are straightforward:
MODULE status_9000 OUTPUT.
SET PF-STATUS '9000'.
IF go_docker IS INITIAL.
    CREATE OBJECT go_docker
           EXPORTING no_autodef_progid_dynnr = 'X'.
ENDIF.
ENDMODULE.
with at least the function code ONLI defined in PF-status 9000 and
MODULE user_command_9000 INPUT.
IF gv_okcode = 'ONLI'.
    SUBMIT z_sample_report AND RETURN.
ELSE.
    LEAVE PROGRAM.
ENDIF.
ENDMODULE.
The report Z_SAMPLE_REPORT can be any report you like.
At last the function module contains the following code:
FUNCTION z_show_dynpro.
*"*"Lokale Schnittstelle:
CALL SCREEN 9000.
ENDFUNCTION.
As I see this, this is a straightforward application of the working example at the top and the principles of MVC and encapsulation of the dynpro logic (to "avoid" global variables as best as possible).
Clearly in some sense this is an academic question, but I have built a fairly big application like that up to now ...

Thanks for reading and contemplating,
Thomas

You'll either have to pass the data in as parameters in the applet tags or create a JavaScript tag and have the JavaScript pass it in. If the array is very large then you open a connection between the Applet and a servlet and pass the data that way.

Re: Is it possible to change row colors on array fields ors

HI Martin!
Yes, it is possible to change row colors on array fields.
I have attached a PEX (tools.pex) which has an object which changes FillColor
and PenColor for Arrays. The PEX has it's own test window, so you can try
various combinations. (There are a few other Objects in the Project which are
not relevant
I'm not sure that you can change colors on individual choices in a scroll list.
I haven't tried playing around with it.
The test window actually changes the color of scroll lists as well.
The object keeps track of which rows have changed color, same with pen color, so
that when you scroll it keeps track of which rows are a different colors.
The pex is self-contained, just import the file and do a test run.
Please let me know if you have any problems.

Is it possible to change row colors on array fields or scroll lists?
I need to create a list field that will allow me to dynamically change the
fillColor and/or penColor attributes of individual rows. (I just want to
highlight the rows, and those seem to be the obvious attributes...) It appears
you can't do that on scroll lists (the elements are list elements, and don't
have those attributes) and I can't figure out how to do it on an array field
either. Any ideas for how to accomplish this?

Geoff,
May I point out that in your function, the input Row should be converted to:
Row - <theArrayField>.TopRow + 1;
or before calling this function.
Also the AfterFieldScroll event should be handled.

Subject: RE: Focus Highlight Property of an Array Field
Shannon,
As an Express developer, all of my windows get this functionality for
free. Of course this is
due to the fact that all ArrayFields inherit from a class that provides
this functionality.
The following snippet of code could be exactly what you are looking for,
method HighlightRow(input Row : integer)
if (Row >= 0) then
for widget in <DisplayedResultSet>.bodygrid.children do
if (widget.row = Row) then
widget.fillcolor = C_PALEYELLOW;
else
widget.fillcolor = C_WHITE;
end if;
end for;
end if;
end method;
I sure hope this helps you,
Take care

Passing an object accross classes.

Hi all,
I'm trying to declare an object in one class and then pass that instance over to a second class, when I try to run my code I get "Debugger stopped on uncompileable source code" error!
I'm working with a series of JFrames, starting with a "welcome" screen and a "next" button:
    Order[] Order = new Order[99];
    int OrderNumber = 0;
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if (source == btnNext){
            OrderNumber++;
            Order[OrderNumber] = new Order();
            Name Name = new Name(Order[OrderNumber]);
            Name.show();
            this.hide();
    }This sets up a new order and passes the object over to the next JFrame class.
The user enters some information into some text fields which is then stored in the object instance:
    Order Order;
    Customer[] Customer = new Customer[99];
    int CustomerNumber = 0;
    Name(Order Order) {
        SetupUI();
        this.Order = Order;
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if (source == btnNext) {
            CustomerNumber++;
            Order.Customer[CustomerNumber] = new Customer();
            Order.Customer[CustomerNumber].SetName(txtName.toString());
            Order.Customer[CustomerNumber].SetTable(txtTable.toString());
            FirstCourseUI Menu = new FirstCourseUI(Order, Customer[CustomerNumber]);
            Menu.show();
            this.hide();
        }This seems to work fine, the object is passed over and I can commit the information to it. But this too uses the same method to send the objects over to the next JFrame, which should in turn begin adding some items for the customer:
    Order Order = new Order();
    Customer Customer = new Customer();
    FirstCourse FirstCourse = new FirstCourse();
    FirstCourseUI(Order Order, Customer Customer) {
        this.Order = Order;
        this.Customer = Customer;
        SetupUI();
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if(source == btnAdd) {
            String selectedItem = (String)lstMenu.getSelectedValue();
            Customer.AddItem(1, selectedItem);       // PROGRAM STOPS HERE
    }And this is where I run into problems, here is the AddItem method
    public void AddItem(int course, String item)
        int i = 0;
        switch(course)
            case 0:     // Drinks
                break;
            case 1:     // First Course
                while(FirstCourse[i] != null) {
                    i++;
                FirstCourse[i] = item;
                break;
            case 2:     // Second Course
                break;
            case 3:     // Third Course
                break;
            default:
                break;
        }As far as I can tell, this should work fine. I don't think the method itself is broken, the program just never gets to that point!
Any Ideas?
P.S. Sorry about the lack of comments in there, bad practice I know :\

Problem solved!
On the second JFrame where the user enters their name and table number, I was creating an object array of Customer - but my order class already has a Customer array! I was then passing over the wrong object array when the "Next" button was pressed.
    Order Order;
    int CustomerNumber = 0;
    Name(Order Order) {
        SetupUI();
        this.Order = Order;
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if (source == btnNext) {
            CustomerNumber++;
            Order.Customer[CustomerNumber] = new Customer();
            Order.Customer[CustomerNumber].SetName(txtName.toString());
            Order.Customer[CustomerNumber].SetTable(txtTable.toString());
            CoursesUI Menu = new CoursesUI(Order, Order.Customer[CustomerNumber]);
            Menu.show();
            this.hide();
    }It seems to be functioning correctly now :) Thanks for taking the time to look over it steve.

How do I convert an Object into an Array?

If I have an instance of type object that I know is really a DataGrid row that was cast into an object when passed to a function, how can I cast that Object to an array, such that each index of this array would correspond to the information in a given column of the row?

@Sathyamoorthi
Can you please explain what this function does? Essentially, what should be contained in the String?
I printed out the string and it seems like I am getting a random row in the Object, as opposed to first or last. Why is that?
UPDATE: I printed out the value of dataGrid0.columns[5].dataField but it just turned out to be the id of the column.

Trying to pass and object variable to a method

I have yet another question. I'm trying to display my output in succession using a next button. The button works and I get what I want using test results, however what I really want to do is pass it a variable instead of using a set number.
I want to be able to pass the object variables myProduct, myOfficeSupplies, and maxNumber to method actionPerformed so they can be in-turn passed to the displayResults method which is called in the actionPerformed method. Since there is no direct call to actionPerformed because it is called within one of the built in methods, I can't tell it to receive and pass those variables. Is there a way to do it without having to pass them through the built-in methods?

Passing multiple values for a single field in URL to call sap Transaction

Hi All,
I need to pass multiple values for a single field to SAP transaction .
means if i have say a field "Date" which can contain more than one value, <b>but its not a range which has two fields</b> . How is it possible.
Let me know pls.
Regards,
Sirisha.R.S.

Hi Satyajit,
I need to call a transaction with multiple values which gives me the report based on those values.
So I need to pass multiple values for a single parameter.
I hope u got it.

How can i convert object to byte array very*100 fast?

i need to transfer a object by datagram packet in embeded system.
i make a code fallowing sequence.
1) convert object to byte array ( i append object attribute to byte[] sequencailly )
2) send the byte array by datagram packet ( by JNI )
but, it's not satisfied my requirement.
it must be finished in 1ms.
but, converting is spending 2ms.
network speed is not bottleneck. ( transfer time is 0.3ms and packet size is 4096 bytes )
Using ObjectOutputStream is very slow, so i'm using this way.
is there antoher way? or how can i improve?

thanks a lot for your reply.
now, i use udp socket for communication, but, i must use hardware pci communication later.
so, i wrap the communication logic to use jni.
for convert a object to byte array,
i used ObjectInputStream before, but it was so slow.
so, i change the implementation to use byte array directly, like ByteBuffer.
ex)
public class ByteArrayHelper {
private byte[] buf = new byte[1024];
int idx = 0;
public void putInt(int val){
buf[idx++] = (byte)(val & 0xff);
buf[idx++] = (byte)((val>>8) & 0xff);
buf[idx++] = (byte)((val>>16) & 0xff);
buf[idx++] = (byte)((val>>24) & 0xff);
public void putDouble(double val){ .... }
public void putFloat(float val){ ... }
public byte[] toByteArray(){ return this.buf; }
public class PacketData {
priavte int a;
private int b;
public byte[] getByteArray(){
ByteArrayHelper helper = new ByteArrayHelper();
helper.putInt(a);
helper.putInt(b);
return helper.toByteArray();
but, it's not enough.
is there another way to send a object data?
in java language, i can't access memory directly.
in c language, if i use struct, i can send struct data to copy memory by socket and it's very fast.

I am trying to set this map data using java code ,
     HashMap procADMap1 = new HashMap(5);
               PropertyTypeWS pType = new PropertyTypeWS();
               pType.setTypeIndex(2);
          AppdataDefImplWS appData1 = new AppdataDefImplWS();
          appData1.setName("Project");
          appData1.setType(pType);
          appData1.setMaxSize(400);
          appData1.setLOB(false);
     appData1.setDefaultValue("Project Default value");
          procADMap1.put(appData1.getName(), appData1);
          setVariableData("request","createNs","/createNs/namespaceData/appdataDef",procADMap1);
Then I am passing request object to the method which I want to invoke from bpel process.
I am able to deploy the application but when I do post message I am getting following exception,
NamespaceWithMap (createNamespace) (faulted)
[2004/09/09 18:35:54] "{http://schemas.oracle.com/bpel/extension}bindingFault" has been thrown. Less

code: {Server.userException}
summary: {org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.}

Is there any other way to handle Map type in bpel process?
Thanks in advance,
Sanjay

Thanks for the quick reply.Actually the web service is already deployed on the server.What I want to do is use existing wsdl file of the deployed web service and invoke the method of the same using oracle PM.
If I remove element which uses apachesoap:Map type it just works fine also I am getting the complex object returned by the web service method.But when I try to set appDataDef which is of type apachesoap:Map(Axis conversion for java.util.Map and it uses namespace xmlns:apachesoap="http://xml.apache.org/xml-soap") I am getting the error.
Can you give me some direction to use this exising wsdl file to set map object or it is not possible.

Converting object wrapper type array into equivalent primary type array

Hi All!
My question is how to convert object wrapper type array into equivalent prime type array, e.g. Integer[] -> int[] or Float[] -> float[] etc.
Is sound like a trivial task however the problem is that I do not know the type I work with. To understand what I mean, please read the following code -
//Method signature
Object createArray( Class clazz, String value ) throws Exception;
//and usage should be as follows:
Object arr = createArray( Integer.class, "2%%3%%4" );
//"arr" will be passed as a parameter of a method again via reflection
public void compute( Object... args ) {
    a = (int[])args[0];
//or
Object arr = createArray( Double.class, "2%%3%%4" );
public void compute( Object... args ) {
    b = (double[])args[0];
//and the method implementation -
Object createArray( Class clazz, String value ) throws Exception {
     String[] split = value.split( "%%" );
     //create array, e.g. Integer[] or Double[] etc.
     Object[] o = (Object[])Array.newInstance( clazz, split.length );
     //fill the array with parsed values, on parse error exception will be thrown
     for (int i = 0; i < split.length; i++) {
          Method meth = clazz.getMethod( "valueOf", new Class[]{ String.class });
          o[i] = meth.invoke( null, new Object[]{ split[i] });
     //here convert Object[] to Object of type int[] or double[] etc...
     /* and return that object*/
     //NB!!! I want to avoid the following code:
     if( o instanceof Integer[] ) {
          int[] ar = new int[o.length];
          for (int i = 0; i < o.length; i++) {
               ar[i] = (Integer)o;
          return ar;
     } else if( o instanceof Double[] ) {
     //...repeat "else if" for all primary types... :(
     return null;
Unfortunately I was unable to find any useful method in Java API (I work with 1.5).
Did I make myself clear? :)
Thanks in advance,
Pavel Grigorenko

I think I've found the answer myself ;-)
Never thought I could use something like int.class or double.class,
so the next statement holds int[] q = (int[])Array.newInstance( int.class, 2 );
and the easy solution is the following -
Object primeArray = Array.newInstance( token.getPrimeClass(), split.length );
for (int j = 0; j < split.length; j++) {
     Method meth = clazz.getMethod( "valueOf", new Class[]{ String.class });
     Object val = meth.invoke( null, new Object[]{ split[j] });
     Array.set( primeArray, j, val );
}where "token.getPrimeClass()" return appropriate Class, i.e. int.class, float.class etc.

How to pass an object as method parameter

Hi Guys
I was testing a simple program and was trying to pass an object to a method but it didnt seem to work and I couldnt find out WHY.
I am posting the code so please let me know who can i make my method ADD_EMPLOYEE work so that when i pass an object of LCL_EMPLOYEE, it updates I_EMPLOYEE_LIST.
