Flexible code

I made a text item and made pl/sql for the text item as;
:status_control_block.current_block := :SYSTEM.CURRENT_BLOCK;
got the following error message;
error 49 at line 1
bad bind variable 'status_control_block.current_block'
and I got it from a book, Enhanced Guide to Oracle 8i.

The code expects you to have created a block in your form called "status_control_block" and a field inside theat block called "current_block"

Code gives error supposed to compare pairs

question is
Expand Pair.java by testing it with at least 4 more differing Pair combinations (both primitives & classes). Find (or write) at least one other set of Pair that you can compare without altering the comparePairs method.
public class Pair<K, V> {
K key;
V value;
public void set(K k, V v) {
    key = k;
    value = v;
public K getKey() { return key; }
public V getValue() { return value; }
public String toString() {
    return "[" + getKey() + ", " + getValue() + "]";
// Comparing Pairs - Slide 34
public static <K extends Comparable,V,L,W> int
      comparePairs(Pair<K,V> p, Pair<L,W> q) {
    return p.getKey().compareTo(q.getKey());
    // p's key MUST implement compareTo
/* IMPORTANT: This is very flexible code BUT it does

Comparing vector to part of a string

I have a file that contains this as the first part of the line:
S1| some other data
S2| some other data
S3| some other data
I have my code like this:
Vector row = new Vector();
while (tokens.hasMoreTokens()) {
row.addElement(tokens.nextToken());
System.out.println("row = " + row.get(0));
try {
if (row.get(0).equals("S")) {
Now, I know that equals will not get the S1, S1, S3, but is there some kind of like statement or wild card that I can use to compare the first element in the file? I need to keep both the S part and the number part, but just want to use the S part in the if statement. Does this make sense? Thanks.
Allyson

You can use the String.regions match method.
If this is needs to be highly modifiable and flexible code you might want to look into the regex library. It is part of 1.4 and is available as an extension to 1.3
P.S. If you are using anything above 1.1 avoid Vector. Use the ArrayList class instead.

Detecting sandbox

Hello!
I would like to detect, if my application is running inside or outside a Java sandbox. Reason: I would like to keep the flexibility to use my application as signed and unsigned Web Start application as well as regular application.
Up to now I use code like this:
import javax.jnlp.*;
boolean runningInSandbox ;
try {
    BasicService bs =
        (BasicService) ServiceManager.lookup("javax.jnlp.BasicService");
    runningInSandbox = true;
} catch (UnavailableServiceException e) {
    runningInSandbox = false;
if (runningInSandbox) {
}Ok, this code seems to work, but I guess, there should be a better way. Is this the "official" documented procedure or does anybody know a better way? (Technically this just checks, if the ServiceManager can find the BasicService; not finding this service doesn't mean, my application is running outside of any sandbox.)
Kind regards,
Marcus.

This is the correct way to determine if your code is running under Java Web Start, however, that is not necessarily the same thing as knowing if the code is running in the sandbox. It is possible to be running
1.) outside of java web start, but with a security manager installed that
implement the sandbox or some other permission collection.
2.) under java web start with j2ee-client-permissions or all-permissions
granted by signing your code and requesting this in the jnlp file.
3.) under java web start with enhanced permissions granted by user or
system-wide policy files.
Although for many applications, the method you describe is enough, the best way to keep flexible code is to check for the specific
permission you want to use before using it:
SecurityManaget sm = System.getSecurityManager();
boolean granted;
try {
if ( sm != null ) {
sm.checkPermission(XXX)
granted = true;
} catch (SecurityException se) {
granted = false;
if (granted) {
// one path if permission is granted
} else {
// another path if not.

Can anyone help me with a simple java programm in linux?

i just started learning how to write java code in high school and we had an assignment which required us to write a program that would calculate the amount of kilometers u traveled into miles and vis-versa but we had to give the user a chance to pick which one they had to do and our teacher told us to give them the option using 1 to calculate from kilometers to miles and 2 to calculate miles to kilometers .....
and i got confused so please help

Good luck.galaxyboy25,
This is very good advice. Getting into the habit of working out problems on paper/whiteboard first will save you many a headache later on. I'm relatively new to programming as well (only about 2 years professional experience) but this technique has helped me immensely in my work. In my mind, writing code is easy--figuring out what to write is where the real challenge is.
One other thing. In addition to sketching your problem on paper, it always helps to break a problem into very small, simple, and easily solvable pieces. Then put them together. In doing this you will find that not only will this make your task of problem solving much easier but you also end up writing cleaner and more flexible code.

Warranty mgmt solution-questionnaire

Hi, gurus,
my clients want to implement warranty solution. for that i need quesionnaire for gathering information of existing process, please send me list of questions, so i can make AS IS analysis based on my client's answer.
My id is [email protected]
reward will be given
regards
pinal

Dear Deve,
I am very sorry to inform you that, don't show your gimmick in your questions saying that rewad will be given. We are sharing our knowledge for the benefits of the SAP Community.
With regard to Warranty Management Q&Adb.....you will get it from SAP Marketplace.
SAP Warrant Management - Solution Brief:
SAP Warranty management plays a crucial role in any industry since it allows automatic, quick processing of warranty claims, leading to improved customer
satisfaction and potentially untapped vendor warranty recovery.
SAPs best-of-breed Warranty Claims functionality combines a new, flexible document structure with the power of proven SAP technologies. This enables a
highly customizable and versatile Warranty Claims engine. The Implementation of SAP Warranty Claims is considered to be a natural progression in building a
well-rounded SAP system.
High Degree of Re-Use: Much functionality is re-used from other SAP
applications, e.g. pricing, output determination, IDOCs, account determination, CO-PA, code catalogs, etc.
Easy to extend: The Warranty Claims application has an openframework with a plethora of User Exits, BADIs & BAPIs, available for project teams to add custom
functionality without modifications.
Web Interface: Integrated with the new SAP Web Application Server, a Web
claim process can easily be extended to customers, vendors, dealers, service centers, as well as to claim administrators, directly over the Internet.
Quality Defect Reporting: Standard reports and integration with Business
Warehouse (BW) reporting greatly enhance visibility of quality defects and various trend analyses.
Claim validation Avai lable via easy-to-use graphical rules and validations editor.
Line item validation Complex body of rules can be expressed.
Pricing calculation and adjustment Integrated with standard SD pricing, references standard price catalogues, or sets up warranty-specific pricing.
Automatic or manual approval Approve/disapprove, partially approve items/header in claims
Web interface Part of Netweaver, the Web Application Server integrates web processing with warranty claims applications. Web enabling the complete claim life cycle. Following is a selection of out-of-the-box Web functionality:
- Claim entry, claim validation, line item validation
- Catalog select ion
- Calculate claim pricing
- Claim status and final adjudication review
Interfaces to multiple channels, e.g. via XML Any interface can be linked into SAP Warranty. Out-of-thebox EDI via IDOCs, Microsoft .net applications can be
integrated into BAPI RFCs. Thus, XML communication via EDI, Email, or HTTPS can be set up.
Security Application provides the security necessary to restrict informat ion available to user roles and profiles.
Maintain claim history Flexible new document structure allows the maintenance of several versions and several claim copies grouped under one claim.
Service Bulletins Support for recalls or service bulletins with serial number effectiveness and SB specific pricing.
Quality capturing Flexible code catalogs on item level allow statistical reporting and analysis. Ability to create a Quality Notification linked to the claim.
Vendor recovery Recover warranty costs from vendors or other reimbursers. Can be part/serial number specific.
Integrated to Sales and Distribution Module: Service and Maintenance Create sales orders and spares shipments free of charge, integrate with service
notifications and orders. Integration with service management.
Claim Splits Capability of splitting charges across multiple vendors/reimbursers.
Reporting Online on-demand reporting capability, allowing business users to perform detailed analyses, reporting by product models, groups, codes, and cost,
e.g. parts leading to highest claim payments.
Integrated to revenue and cost controlling reporting
environment (CO-PA).
Integrated to Business Warehouse with standard
info cubes and reports.
Hope this information will be useful.

I can see that the books that I have do not include about 10-12 chapters for example:
Writing Flexible Code
Creating a Menu Module
Managing Menu Modules
Programming Function Keys ... etc
Is there any other book that I am missing, can you please provide me any details ? I'll appreciate.

Try catch + wait in pl/sql?

what are possible approaches to write procedure that:
1) tries to make update/merge
2) if update/merge fails for any reason then it waits 10s and tries again
3) maximum allowable trial counter is 6
4) if it cannot do update/merge without an error during those 6 attempts it finishes and passes original error code to the application
I would appreciate your suggestion about coding such procedure.
thank you

I would appreciate your suggestion about coding such procedure.Procedures. Plural. Structured and modularised programming. Non-negotiables ito writing robust, maintainable and flexible code. And the above logic needs more than one code unit.
From a pure coding perspective, writing this is not a problem. DBMS_LOCK is used for sleeping a number of seconds. A loop and a counter is needed to control loop execution. An exception handler in the loop for handling loop logic (successful iteration, another iteration, throw error up call stack).
However, from a software engineering perspective I do not see this as a solution. It is a hack. A very poor hack at that... attempting to fix a problem via addressing the symptoms.
Why would the merge fails? Why will waiting 10 seconds "fix" the cause of the failure? Why hit the same brick wall repeatedly (up to 6 times), spending expensive server resources in doing that?
I would rather determine the actual problem and address that, instead of putting a hack in place trying the Large Hammer approach...

Invalid adapter name"c/CVI Flexible Prototype Adapter" Error code:-17336.

Hi,
After replacing the mainboard of the test computer and activating Windows, test station shows "Invalid adapter name"c/CVI Flexible Prototype Adapter" . Invalid adapter name. Error code:-17336" when we try to run TestStand Sequence(4.2.1.83). Could you help to guide. Thanks!
Daniel

Hi Daniel,
I would agree with Doug regarding checking the licensing in the License Manager, deactivating if it is activated and then reactivating. It is possible that the MAC address changed when you switched out the motherboard and this would cause the computer ID to change and render your current licensing invalid. If this does not solve the situation, could you specify when this error occurs? Is this when you open Teststand or when you try to run a particular program? Do you have a base or debug deployment Teststand license?
I look forward to your response and hope that you have a great day!

Flexible DLL error code message

HI,
I'm using a flexible DLL Action step (C/C++ DLL).
The Returned value go to a local error variable.
The result Action is set to 'If value < 0 Set Error occurred to true'
Set ErrorCode is checked.
Now, I get a run time error with the error code displayed. I would also like to display an error message. How can I do that.
I can write the messages myself based on the error code in case the dll does not return a code message (which I don't know how to check).
Thanks

PL/SQL code written in db or in application...????

Hi ,
Which is the best...at performance , maintability... e.t.c.???
To write PL/SQL as validation process of data values going to be inserted in db:
1) as db trigger (before insert or update row-level trigger)
2) in application level - in Forms10g...
This PL/SQL code compares some pairs of data values only.... there DML statement....
Both db server and App server are considered to be or in the same machine or in two machines very close to each other...
Note: i use Db10g .
Thanks...

It is all about moving parts. How many there are. Where they are located.
The less moving parts, the less the complexity, the bugs - and the better the performance (less wheels to turn to crunch data), the easier the maintenance and the better the flexibility.
Part of this is having the moving parts close to the data. Kind of obvious - what is faster? Shipping data from the db engine to a front-end application via a app server and web server? Or shipping the data from the db (SQL) engine to a PL/SQL process running as part and parcel of db instance? IPC is significantly faster than TCP/IP.
Having the moving parts close to the data also means that it can scale with the data. Oracle is good at scalability. It is designed at its very core to be scalable. Partitions to reduce I/O. Shared Server to reduce o/s resource footprint per client session. Shared pool to re-use SQL. DB buffer to cache data. RAC to run multiple db instances for a single physical database. Etc. Etc.
With the application moving parts being close to the data, it inherits this scalability. You can "multi-thread" application code using table pipelines. You have access to forking application code using background processes (DBMS_JOB and DBMS_SCHEDULER). You have bulk processing in order to transfer more data per SQL engine call, between the buffer cache and your application, and thus also reduce expensive context switching.
This list goes on and on.
All this is summarised into the following rules.
Rule 1. Do it in SQL.
Rule 2. Only when SQL cannot do it, use PL/SQL. (e.g. SQL is not suited for managing and controlling process flow - PL/SQL is)
Rule 3. Only when PL/SQL cannot do it, use <insert-language-here> (e.g. PL/SQL cannot render a Windows grid on the client - but Delphi/C#//Java can).
Also keep in mind that in the modern client-server paradigm we deal with a web architecture. Which means the client is a web browser. And this means that PL/SQL can pass the data (HTML) required by the client (web browser) to render the User Interface.
Have a look at APEX (Oracle's Application Express) for how this works. http://apex.oracle.com
All you need to develop web applications is APEX (a PL/SQL product suite in the database) and a web browser. Kickass stuff... :-)

I can't don't understand code in netbean and it's about Jframe.

i use netbean to design 2 jframe with some buttons on both frame.
frame1 is login form, frame2 is mainform. i want to show loginform then click the button1 to show 2nd jframe.
then i click exit on 2nd jframe and it come back to loginform(frame1).
i do alot of search on the google and here. i know the basic to show a jframe using
setVisible or .show() .hide(), etc..
the problem is what is my jframe variable name in netbean?
i know i can create an jframe object
such as: JFrame frame1 = new JFrame(); etc.. (it's ok if the syntax is wrong for now).
When i use netbean, i drag the Gui components to the Jframe. The jframe is generated by netbean automatically.
When the main program runs, it calls main() method, follow by :
public void run() {
new LoginForm().setVisible(true);
new LoginForm().setVisible <--- setVisible(true) means show the form.
and is new LoginForm() create an object from LoginForm class.
public LoginForm() {
initComponents();
When it create a new object, it runs default constructor and calls iniComponoents and finally show the jframe.
my question is when you create object, you usually declare variable and use variable to hold reference to the object.
that's why i don't understand how it works here.
it only create news object, bu no variable to holding it. how do i control this Jframe to show and hide without a reference variable????????????

i tried hand-written code, and it looks just fine when design few buttons, labels and textfields.
The adjustment of buttons(labels) are not that good on the frame.
However, when you use IDE, you can drag the button on any spot you like in the jframe.... and in the process not learn how Swing works, and lose flexibility and power. Sorry to sound conceited, but I'll match any of your netbeans-created GUI's with one of my own, and mine will likely be better -- and I'm not all that good at this just yet.
Much luck.

Is There ANY Flexibility in BS Acct Assignment for Sales/Purchase Invoices?

We are about to go live; and, we have a Chart of Accts that not only breaks out our Income Statement accounts by division, but also does so for our Balance Sheet accounts. Even so, apparently B1 does not have the flexibility to modify the balance sheet acccounts used for tracking Accounts Receivables and Accounts Payables at the marketing document level. Since Business Partners may be purchasing (in the case of Customers) or selling (in the case of vendors) from any of our three divisions, we cannot setup a single AR or AP account in the BP record. So, how do we best modify the B1 setup to have a manageable level of work to separate these transactions out into the multiple accounts? Our ultimate goal is to be able to create three different BS, IS and SCF reports for each division. However, the complexities of this larger task will be addressed later. We have the SDK and are willing to make system modifications using this tool if we can achieve our desired result.
Thank you for any and all assistance!
Message was edited by: Scott Young
I suppose I should also ask how cash and cash-equivalent BS accounts could be split out when receiving payment...

Felipe, I GREATLY appreciate your response. Your comments regarding means to simplify my creation of trials balances is appreciated. However, I will not have the opportunity to put this to good use if I am not able to separate out the original data entry.
I still do not see how to modify the default AR or AP account on a document. Recall, any of my customers may be purchasing from any of the company's three divisions; and, any of my vendors may be selling to any of the three divisions. Further, we do not want to maintain separate BP records for each customer, since this will require undue maintenance and/or problems with reporting. I simply wish to have control of the AR and AP accounts used in the journal entry associated with an AR Invoice and AP Invoice. I want to use division-specific balance sheet accounts instead of the one noted in the BP record.
If I can obtain an answer for this, this I would also be interested in how to perform the same split for the several other balance sheet accounts, including (but not limited to) the Goods Clearing account, Inventory Returns account, Cash at Bank account, AR Adjustments account, et al.
Thank you again! If SDK changes are needed, this would be fine; but, any example of how to perform the code changes would be very much appreciated. This would be my first jounral entry modification with the SDK.
Kind Regards,
Scott Young

Sales analysis by document shipping code (Logistics - Ship to)

I wish to either sort the Sales Analysis report by the BP Shipping Address (of documents) or create a similar report through XL Reporter (current version is 2007A PL:38)
Basically, we have a need to report a particular customer's recent purchases (date range) of a specific line of items (item range) filtered by one specific shipping address (customer has one billing address and several shipping addresses).
The Sales Analysis report seems very static in the sense that you cannot add additional fields to the output of the report (after being generated) via the Forms Setting button. Also, while the Items tab of the Sales Analysis report satisfies part of need to report by date, range, item range and customer range, but we can not filter or drill down effectively to know what items were shipped to specific drop location (ship-to-address).
In XLR, I have only had success in filtering dimensions (not light dimensions). I suspect I could bring the Business Partner and Ship-to Code to the Selection area and filter the BP by CardCode (this is a dimension) and then manually create an expression similar to OINV ( ShipToCode = "PlaceXYZ" ) with the intention of filtering the results by the document ship-to code.
If XLR is used, I would like to be able to filter by "closed" A/R Invoices only if someone could help with this aspect as well.
I seem to have hit a stumbling block with these two avenues so I would greatly appreciate some assistance. Thanks in advance.
Best regards,
Pat
P.S. If anyone knows of any good online resources for XL Reporter could you please share a link?

Hi Pat,
Based on what you need to do, I suggest you just using query since it has the greatest flexibility. If you concern about the format, QLD can be used for basic formatting so that you can have a "Report".
Thanks,
Gordon
