Question about using Functions in BC4J

I know that it is possible to call a store procedure from a ViewObject using a DataWebbean can I do the same thing but calling a function.
Please I need to know, as soon as possible because I am working on it.

Following are two ideas but to tell you truth still I am looking for better way.
1-convert your function to a procedure and execute it as a procedure.
2-Execute a direct select statement against database function as follow.
String sQuery = "SELECT func_name() FROM dual";
DbAccess db = SessionInfo1.getDbAccess();
Object dynamicQueryRowsetAccess = db.executeRetrieval(sQuery,"infobus:/oracle/SessionInfo1/DynamicQuery",null);
if ( dynamicQueryRowsetAccess instanceof ScrollableRowsetAccess ){
ScrollableRowsetAccess rs = (ScrollableRowsetAccess)dynamicQueryRowsetAccess;
if (rs.getRowCount() > 0){
//take the value returned by function here
null

Have a question about using functions in JSP 2.0

Hello,
Does someone try to create functions in JSP2.0?
the following codes is from http://developer.java.sun.com/developer/technicalArticles/javaserverpages/JSP20/
Code Sample:math.jsp
<%@ taglib prefix="my" uri="http://jakarta.apache.org/tomcat/jsp2-example-taglib %>

<P>
<FORM action="math.jsp" method="GET">
   X = <input type="text" name="x" value="${param["x"]}">
   <BR>
   Y = <input type="text" name="y" value="${param["y"]}">
   <input type="submit" value="Add Numbers">
</FORM>
<P>
The sum is: ${my:add(param["x"],param["y"])}
</BODY>
</HTML>Compute.java
package jsp2.examples.el;
import java.util.*;
public class Compute {
   public static int add(String x, String y) {
      int a = 0;
      int b = 0;
      try {
        a = Integer.parseInt(x);
        b = Integer.parseInt(y);
      }catch(Exception e) {}
      return a + b;
}I put function tags in C:\Tomcat\webapps\jsp-examples\WEB-INF\jsp2\jsp2-example-taglib.tld
<function>
        <description>add x and y</description>
        <name>add</name>

        <function-signature>int add(java.lang.String,java.lang.String)</function-signature>
    </function>But get the error messages:
The server encountered an internal error () that prevented it from fulfilling this request.
org.apache.jasper.JasperException: /jsp2-tutorial/math.jsp(11,22) equal symbol expected
Am I missing somethig?
Thanks.

Well, i think the code is perfectly fine , what you should look after : is there any servlet.jar exist in the jre/lib/ext on you java sdk ,you can determine whether EL 2 works by trying some jsp 2 examples provide with tomcat 5 alpha version .
If it works , then it is not the alternative servlet.jar issue , most probably is your configuration errors.
I have try my custom function and it worked well under tomcat 5 after resolving the earlier servlet.jar issue.
By the way you don't have to put your tld file as described , simply place it under your /WEB-INF and edited your tomcat 5 web.xml to like my example given below .
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd"
version="2.4">
<display-name>Display Name of the application</display-name>
<description>
application name
</description>
<jsp-config>
<taglib>
<taglib-uri>
your tld file
</taglib-uri>
<taglib-location>
/WEB-INF/your tld file.tld
</taglib-location>
</taglib>
</jsp-config>
</web-app>
Please give it a try and let me know whether it works , I will provide more assistance if required.

Question about the function module (RFC_READ_TABLE)

Dear everyone
Could I ask you a question about the function module (RFC_READ_TABLE)?
I was asked if it's possible to create a report which compares the data between different SAP systems (both production systems).
Now, the easiest way would be to use the function module (RFC_READ_TABLE) within a SAP infoset query (SQ01 type query).
But I heard the rumor that using the function module (RFC_READ_TABLE) is not advisable due to the security reason.
However, I am not exactly sure what sort of security problems this function module can possibly have...
Would you help me on this?
I also would like to know if using "remote enabled module" type function module can always overcome this possible security issue.
Or, are there any points that I need to be careful about even when I use "remote enabled module" function module?
Thank you very much in advance.
Takashi

Dear Fred-san
Thank you very much for your support on this.
But, may I double check about what you mentioned above?
So, what you were mentioning was that if some user executes the query with
the function module (RFC_READ_TABLE), under the following conditions, he can access to
the HR data even when he does not have the authorizations for HR transactions?
<Conditions>
1. the user has the authorization for HR database tables themselves
2. RFC_READ_TABLE is called to retrieve the data from HR database
<example>
Data: LF_HR_TABLE like DD02L-TABNAME value 'PA0000'.
CALL FUNCTION 'RFC_READ_TABLE'
   EXPORTING
    query_table                = LF_HR_TABLE
TABLES
   OPTIONS                    =
   fields                     =
   data                       =    .
But then, as long as we call this function module for a non-critical tables such as
VBAP (sales order) or EKKO (purchase order) within our query, it wouldn't seem to be
so security risk to use RFC_READ_TABLE...
Besides, each query (infoset query) has got the concept of user groups, which limits
the access to the queries within the user group.
※If someone does not belong to the user group, he cannot execute the queries within that
   user group, etc
So, my feeling is that even infoset queries does have authorization concept...
Would you give me your thought on this?
I also thank you for your information for SCU0.
That is an interesting transaction
Kind regards,
Takashi

I have a question about using multiple ipads in our school. Each of our teachers have a iPad and AppleTV in their classroom. The issue is, with our classrooms so close in proximity to one another, is there a way to pair teacher

I have a question about using multiple ipads in our school. Each of our teachers have a iPad and AppleTV in their classroom. The issue is, with our classrooms so close in proximity to one another, is there a way to pair teacher #1 iPad to its AppleTV without effecting/projecting onto the adjacent teachers #2 classroom AppleTV?

Not as such.
Give the AppleTV units unique names and also enable Airplay password in settings with unique passwords for each teacher.

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Question about using new battery in old Powerbook

I have a pre-intel Powerbook G4, and the battery is pretty much toast (lasts about 15 minutes now). I have ordered a new battery for it, and I have this question about using it:
Am I smarter to keep the new strong battery out of the PB most days (as I usually work with it plugged in at home) and just pop it in when I know I will be out surfing on batteries? Or is it just as good living in my laptop 24/7 and only occasionally being called upon to do its job?
Current bad Battery Information below:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1144
Remaining Capacity (mAh): 1115
Amperage (mA): 0
Voltage (mV): 12387
Cycle Count: 281
thanks folks, Shereen

Hi, Shereen. Every Powerbook battery wants to be used — drained and then recharged — at least every couple of weeks. If you've always used your Powerbook on AC power nearly all the time, and not followed that pattern of discharging and recharging the battery every week or two, it's possible that your use habits have shortened the lifespan and prematurely diminished the capacity of your old battery. Of course it's also possible that your battery is merely old, as a battery's capacity also diminishes with age regardless of how it's used. You didn't say how old the battery is in years, so this may or may not be an issue. I mention it only because it can be an issue.
For general information on handling a battery for the longest possible lifespan, see this article. My advice on the basis of that article and long experience reading these forums is that it would be OK to do as you propose, but I doubt that you'd derive any significant benefit from it. You would still want to be sure of putting the new battery through a charge/discharge cycle every week or two, even if you didn't have a reason to use the Powerbook away from home or your desk, because sitting unused outside the computer is just as bad for a battery as sitting unused inside it. And you should never remove the battery from your computer when it's completely or almost completely discharged and let it sit that way any longer than a day or two.

Question about using TVARV in an ABAP program

Hello gurus, Im sorry about the silly question.
I have a question about using TVARV in an ABAP program.
A program is presenting a problem and I think that in this code:
SELECT SIGN OPTI LOW HIGH
FROM TVARV
INTO TABLE R_1_163431035_VELOCIDADE
WHERE NAME = '1_163431035_VELOCIDADE'
AND    TYPE = 'S'.
IF ZMM001-VELOCIDADE_B   IN R_1_163431035_VELOCIDADE AND
      ZOPERADORAS-OPERADORA = 'ABCD' AND
      ZMM001-MATERIAL       IN R_1_163431035_PRODUTO.
ELSE.
ENDIF.
What happens is that the value "ZMM001-SPEED" B not exist in "R1_163431035_VELOCIDADE" but the program executes commands under the IF and not under the ELSE, as I imagine it would work. Is this correct ?
I am new to ABAP programming, but I have a lot of XP in other programming languages and this makes no sense to me.
Anyone know where I can find some documentation of the use of "TVARV" in ABAP programs?
I search the Internet if other programmers use TVARV this way, but found nothing, which leads me to think that was a quick and dirty solution that used here.
If this is a bad way to program, what would be the best way?
Regards
Ronaldo.

Hi Ronaldo,
But in this case, the range is not empty, there are 17 records, in this way.:
For the column "SING" all values are "E"
It means that the result is false if ZMM001-VELOCIDADE_B has the same value as one of the 17 records (E = exclude).
For instance, if it has value 'C' and one of 17 records matches C, then the result is false.
The "IF" with "IN" using "TVARV" as used in the program of the post above has the same behavior of a selection screen?
Yes, the same behavior as the selection criterion to be exact. You can press the help key in the complex selection dialog for more info.
I know it's a silly and very basic question, but other language that I used, only the SQL has the "IN" operator, but I think they work in different ways, so I would like to understand how it works in ABAP.
Not silly ;-). Yes they work differently.

Question about Using PAPI Web Service in PowerBuilder 9

Hi, all.
I Have a simple question about using papiws in power builder 9.
In pb9, I created a new Web Service Proxy Wizard and I input a url for papiws(ex. http://seraphpernote:7001/papiws/PapiWebService) and click next.
But I couldn't get any Service List.
In Eclipse, I used this url for using papiws well.
Does anybody know about this case??
help me plz.

IIRC you must activate PAPI-WS for the engine. In Studio you do it by right-clicking on the project, then "engine preferences". In enterprise/standalone you must activate PAPI-WS in the Admin Center.

Question about using 10g/11g and APEX ...

Hi,
I just recently learned of Oracle's APEX and have a few questions about using it.
Can I use APEX with express, standard, and enterprise editions of 10g and 11g?
Are all of these free to use?

You might want to read about APEX rather than jumping into questions that are reasonably well documented. Info at http://www.oracle.com/technology/products/database/application_express/index.html
Your specific questions:
1) Apex is a package that can be installed into any properly licensed database.
2) The price for the production license of the database varies by edition.
The price for Express Edition is $0 for use in production. Part of the cost for that edition is 'no Oracle Support based support, no patches, data volume limitation, etc.'

Question about using Runtime.getRuntime();

hi all
i have a question about using Runtime.getRuntime(). if i use this to get a runtime reference to run an external program, is it considered as starting a new thread inside the thread that starts it?
is it safe to do it in the Session EJB? if not, what can you recommand to do it? thanks

hi all
i have a question about using Runtime.getRuntime().
if i use this to get a runtime reference to run an
external program, is it considered as starting a new
thread inside the thread that starts it? No. Starting a process, starts a process. Threads have nothing to do with it.
is it safe to do it in the Session EJB? if not, what
can you recommand to do it? thanksSo what? Run another process? If you want to run another process in java then your choices are to use Runtime.exec() or use JNI. And using JNI will probably end up doing exactly the same thing as Runtime.exec().
"Safe" is harder. Typically to correctly use Runtime.exec() you must use threads. And as noted threads ideally should not be used. You can use them but if you do you had better understand why they didn't want you using them in the first place. You had also better be sure that you really want to wait for it to complete.
Other than that Runtime.exec() is safe because it can't crash the VM like other interfaces can (like JNI.)

Questions about using the Voice Memos app

I'm currently an Android user, but will be getting an iPhone 6 soon. My most used app is the voice memos app on my Android phone. I have a couple questions about the iPhone's built-in voice memos app.
-Am I able to transfer my voice memos from my Android phone to my iPhone, so my recordings from my Android app will show up in the iPhone's voice memos app?
-When exporting voice memos from the iPhone to computer, are recordings in MP3 format? If not, what format are they in?
-In your opinion, how is the recording quality of the voice memos app?

You cannot import your Android voice memos to your iPhone's voice memo app. You might be able to play the Android memos and have the iPhone pick up the audio and record it.
Here is the writeup about sending voice memos from the iPhone to your computer (from the iPhone User Guide):
App quality is excellent.

Questions about Using APIs to import Bills and Routings - AND COSTS

Hi Forum - the following is a back-and-forth with a customer about use of APIs - Inventory developer suggested I post the question here. Note the 2nd question - and thanks for any assistance.
SR# 7332152.994 ALCOA
Instructions given to ct:
Q1 - Can I load the bill header and components at the same time?
You should be able to load the bill header and components at the same time. Customer loads bill and component data inserting enough "other" data for each so that the bill sequence id will be derived. For the component record, the assembly item, org and alternate_bom_designator values will be used by BMCOIN to derive the bill_sequence_id.
Example:
INSERT INTO BOM_BILL_OF_MTLS_INTERFACE
ORGANIZATION_CODE,
ITEM_NUMBER,
ALTERNATE_BOM_DESIGNATOR,
PROCESS_FLAG,
TRANSACTION_TYPE
VALUES
'M1',
'&PARENT_ITEM',
NULL,
'1',
'CREATE'
INSERT INTO BOM_INVENTORY_COMPS_INTERFACE b
ORGANIZATION_CODE,
ASSEMBLY_ITEM_NUMBER,
ALTERNATE_BOM_DESIGNATOR,
COMPONENT_ITEM_NUMBER,
OPERATION_SEQ_NUM,
COMPONENT_QUANTITY,
EFFECTIVITY_DATE,
PROCESS_FLAG,
TRANSACTION_TYPE
VALUES
'M1',
'&PARENT_ITEM',
NULL,
'&COMPONENT_ITEM',
1,
1,
trunc(SYSDATE),
1,
'CREATE'
Hi Aruna, some additional information that may be useful:
We can load/create the bill header and components at the same time using the scripts given (as above)
Required Data for Creating a Routing : assembly_item_id,
organization_id, routing_type, transaction_type, process_flag
And following scripts can be used to load routing header and operations equences.
INSERT INTO BOM_OP_ROUTINGS_INTERFACE
(assembly_item_id,
organization_id,
routing_type,
transaction_type,
process_flag)
VALUES (2255800,207,1,'Create',1);
INSERT INTO BOM_OP_SEQUENCES_INTERFACE
(assembly_item_id,
organization_id,
operation_seq_num,
Department_code,
effectivity_date,
transaction_type,
process_flag,
operation_description)
VALUES
(2255800,207,100,'ASSEMBLY',
to_date('24-FEB-2009'),'Create',1,
'Paint Wagon');
Q2: One more question, can an expense item can be added to the bill and can contribute the cost.
As there is a confusion of what I asked, below I am rephrasing my question
By an Expense Inventory Item, I mean an item that is just tracked for quantity only i.e.,Checking the attributes - Inventory Item, Stockable, Transactable under Inventory Tab and not checking the attribute - 'Inventory Asset Value'.
My question here is, For these Expense Inventory Items, What is the difference between having the 'Costing enabled' attribute turned ON as opposed to having it UNCHECKED
*Q3 I have tried to load the items and I could only load 1st level of components but could not load second level of bom at the same time.
While inserting I have inserted plan level too.
Please let me know if I have to do anything different to load second level.*
Thanks
James
