Q: difference among these java.protocol.handler packages

Hi,
I have seen posts also AskBEAAnswers talking about using the following three
packages for the protocol handler, what is the major difference among them
and what do they have in common?
-Djava.protocol.handler.pkgs=weblogic.net (or com.certicom.net.ssl or
weblogic.webservice.client)
Someone has used one of the above three.
Thanks.

Oc4j java.protocol.handler.pkgs

Can anyone help, I would like to set java.protocol.handler.pkgs to "com.evermind.protocol|com.sun.net.ssl.internal.www.protocol"
I have tried to modify the default from com.evermind.protocol, using -D and tried to provide the new setting in oc4j.properties. Neither have the desired effect. I have a workaround (set at runtime), but would like to set in *.xml.
In addition, I have looked at the ApplicationServer.class file and I think the above property is 'hardcoded' in the class.
Any help would be appreciated.

Hi Deepak,
Thanks for the reply.
No. The tutorial sample is not deployed to the standalond oc4j server. Instead, I am trying to deploy it against the application server.
I had the problem when setting up the connection to the standalone oc4j server. The connection error was "Error When getting MBeanServer EJB" when selecting Standalone OC4J, or "javax.naming.NamingException [Root exception is java.io.EOFException]" when selecting Standalone OC4J 10.1.3.
Thanks.

Protocol handler in WL6sp1

Hi,
We've written our own url protocol handler for retrieving data with
custom URLs. It works fine in a client application using:
new java.net.URL("protocol://host:port/blah/blah.xml"); //1
and in EJB code using
new java.net.URL(null, "protocol://host:port/blah/blah.xsl", _handler);
//2
but when my custom URLs are invoked in EJB code running inside
WL6 without specifying a Handler (like //1, which is how I need to use
them),
the URL is not recognized : I get a MalformedURLException.
Note that I added a debug statement that checks the value of the
system property java.protocol.handler.pkgs and my package is
correctly listed there after many weblogic packages.
has anyone ever been able to use a custom protocol handler inside WL6 ?
thanks,
Steve

This is the WLE section (the C/C++ product), not WLS (the Java product).
Try reposting -- maybe in the Servlet or Misc section.

Hi,
First, I want to know what kind of Windows do you use? If it is a Windows server system, there might be a security setting that prevents this, you can try to turn it off in this way:
Open the Server Manager, then select IE ESC,
Turn off the Internet Explorer Enhanced security configuration both for administrator and users in the way as the screenshot below:
If you are using a Windows client system, try to add the local address to the local intranet security setting in this way:
Open Internet Explorer, then select Internet option, click “security” item.
Select Local Intranet then click “sites”, then click “advanced”.
Add the local sites as the screenshot below:

Protocol Handler in the applet

Hi.
I 've created a new protocol handler. It's working fine in the application but doesn't work in the applet.
The Handler class is in the package - protocol.xxx
It's registered -
System.getProperties().put("java.protocol.handler.pkgs", "protocol");
However xxx:// is unknown protocol in the applet
Any ideas?
Thanks.

OK, that's why I phrased it as a question. I'm sorry, I'm afraid I'm clueless on this one.

Differences on Windows and Linux JVM about java.util.zip package

Hello, there!
I need some help if someone else has already face this problem.
I have a Java server that process the bytes of a SWF File stored in the server and ouptut it to the user through a Servlet. The file was decompressed and re-compressed using the java.util.zip package (Deflater/Inflater).
Everything works fine on Windows Server 2008 server. But now we need to migrate the server to Linux. The problem is that when I test the website now, the file seens to be corrupted.
What really intrigues me is that everything runs normal on Windows Server configuration, when changed to Linux, the final file seens to be corrupeted... what could possible be the cause? Is there any difference between java.util.zip package on Window and Linux JVM?
My Windows Server is:
. Windows Server 2008 (6.0 - x86)
. Apache 2.2.11
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
My CentOS Server is
. CentOS 5.4 (2.6.18-164.15.1.el5 - i386)
. Apache 2.2.3
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
Please, if someone could give me a lead, I would appreciate very much!
Thank you all in advance,
CaioToOn!

Thank you for the answer, but no. The path is correct.That's not what he meant. Zip file/directory entries are supposed to use / as the path separator. It is possible to use \ but such Zip files will only work under Windows. You may have erred here.Ohhh, I had really missunderstood what Ray said. But, I still think that this is not the problem, since the ZIP is a single SWF file generated by Flex SDK 3.4 and compressed in the ZLIB open standard (as in page 13, at [http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf|http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf] ). This is how Flash Compiler compress the files.
jschell wrote:
If the above suggestions do not solve the problem...Specify in detail with the exact steps used how you determined that it was corrupted.The reason why I believe the SWF is getting corrupted is that when it is loaded by Flash Player (in the client-side) the Player throws a VerifyError: Error # 1033. The [documentation says (see error 1033)|http://help.adobe.com/en_US/AS3LCR/Flash_10.0/runtimeErrors.html] that this error means that the SWF file is corrupted.
As I said, what intrigues me is that this work perfectly in a Windows Server 2008 server. I just had setup a CentOS server and deployed the application. The client-remains unchanged, so why could the result change?
raychen wrote:
I would remove the side effect you are doing and send the file straight through, with decompress and compress, the servlet. It is more likely that you have a bug in your swf processor than the zip library.
I had already tried it when first coding, in Windows Server 2008, it had not worked.
Thank you all for the help.

What is the differences between T=0 protocol and T=1 protocol?..

Hi friends..
Sorry, i want to know what is the differences between T=0 protocol and T=1 protocol?..
Which one is the best, Java Card that support for T=0 protocol and Java Card that support for T=1 protocol?..
Thanks in advance..

Sebastien_Lorquet wrote:
Such protocols have NOTHING TO DO with javacard. They have been existing for YEARS before javacard was invented.
It's just a mean to exchange data with any card. It happens to be a standard, so javacards among others use it to communicate with the host.
the Javacard spec by itself does not know anything about how the APDUs are exchanged . It can be T=0, T=1, T=14, RS-232, GPIB, USB, ISO14443, Felica, Ethernet, Firewire, a satellite link, a deep space link, or anything you want. The comm part is the responsibility of the card operating system, which is out of scope for the javacard machine that lies onto it.
Just because you have a convenience method in the APDU class does not mean this is real. It's up to the card / os manufacturer to define these things, it's reasonable to think they are accurate, but I can create a javacard that claims to be contactless and still will use T=0. That's arbitrary.This is not exactly true. For APDU response chaining to work on some T=0 cards (when using smartcardio that handles response chaining for the developer) we had to use some special tricks. It can also be handy to only allow certain actions on the contact interface (such as admin actions etc) to prevent unauthorised access. The [PLAID Applet|https://www.govdex.gov.au/confluence/display/PLAID/Home;jsessionid=9B9EC664A01EC13B098DDF4EE5760A0A] (developed by the Australian fegral government agency Centerlink) only allows the card to be initiliased through the contact interface.
- T=0 requires a GET RESPONSE additional exchange only for case 4 commands or when the command provides more bytes than requested for an outgoing command. It can also require more than two exchanges if the terminal requests the outgoing data per-block.Don't forget case 2. The GET RESPONSE is at TAPDU layer and is handled internally by smartcardio/PCSC etc and is also handled by the smartcard OS.
Leonardo, if you want to know the differences between the two, I recommend reading ISO7816-3.

Shane

Difference among IDOCS,BAPI,RFC?

what is the difference among IDOCS,BAPI,RFC? and what is the real need to use them and again where exactly these are used in real time applications?

Hi,
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
IDOC type and IDOC. An Intermediate Document (IDOC) type represents the structure of the data associated with a message type (DEBMAS02 for message type DEBMAS Customer Master, and WMMBID02 for message type WMMBXY Goods Movements), while an IDOC is an object containing the data of a particular message type. IDOCs are data containers with intelligence built in. Each IDOC contains one and only one business object. For example, an IDOC of type SHPMNT01, message type SHPMNT, will contain data only of one Shipment Document. Generally, the architecture of an IDOC is independent of the message type by virtue of ALEs ability to redefine it for any message type.

Difference among BAPI,,ALEand EDI

HI ALL.
please tell me difference among bapi, ale and edi
and also send me the material on those topics,
please help me
regards
hussain

Hi,
1) ALE = Application Link Enable: Initially developed for SAP as an abstract layer to extract master and transactional data to be sent ellectronically to other SAP systems. These days is also being used to send data no non-SAP systems. ALE is not a protocol or anything like that, it's just abstract layer composed by a set of applications which are capable of extracting aplication data on a 1-time basis or periodically, by selection criteria or incrementally by deltas.
2) In contrast, EDI = Electronic data interface, this is a comunication protocol not designed by SAP but it´s an industry standard. Of course most SAP software supports EDI, but EDI it's no software but the specification of the protocol in itself.
ALE- is used in scenarios between R/3 and R/3
EDI- is used in scenarios between R/3 and non R/3
BAPI:SAP has introduced object-oriented technology in the R/3 System by making R/3 processes and data available in the form of SAP Business Objects.
External applications can access SAP Business Objects through standardized, platform-independent interfaces - BAPIs. SAP Business Objects and their BAPIs provide an object-oriented view of R/3 business functionality.
Hope this helps.

Using ExecutorService class from java.util.concurrent package

Dear java programmers,
I have a question regarding the ExecutorService class from java.util.concurrent package.
I want to parse hundreds of files and for this purpose I'm implementing a thread pool. The way I use the ExecutorService class is summarized below:
ExecutorService executor = Executors.newFixedThreadPool(10);
        for (int i = 0; i < 1000; i++){
            System.out.println("Parsing file No "+i);
            executor.submit(new Dock(i));
        executor.shutdown();
        try {
            executor.awaitTermination(30, TimeUnit.SECONDS);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        executor.shutdownNow();However, the code snippet above creates all the 1000 threads (Dock objects) at once and loads them to the executor, and thus I'm worrying about memory leak. I haven't tested it on 1000 files yet but just on 50 small ones, and even if the program prints out "Parsing file No "+i 50 times at once, it executes normally the threads in the background.
I guess the write way would be to keep the number of active/idle threads in the executor constant (lets say 20 if the thread pool's size is 10) and submit a new one whenever a thread has been finished or terminated. But for this to happen the program should be notified someway whenever a thread is done. Can anybody help me do that?
thanks in advance,
Tom

Ok I found a feasible solution myself although I'm not sure if this is the optimum.
Here's what I did:
        ExecutorService executor = Executors.newFixedThreadPool(10);
        Future<String> future0, future1, future2, future3, future4, future5, future6, future7, future8, future9;
        Future[] futureArray = {future0 = null, future1 = null, future2 = null, future3 = null, future4 = null, future5 = null,
        future6 = null, future7 = null, future8 = null, future9 = null};
        for (int i = 0; i < 10; i++){
            futureArray[i] = executor.submit(new Dock(i));
        }I created the ExecutorService object which encapsulates the thread pool and then created 10 Future objects (java.util.concurrent.Future) and added them into an Array.
For java.util.concurrent.Future and Callable Interface usage refer to:
[http://www.swingwiki.org/best:use_worker_thread_for_long_operations]
[http://www.particle.kth.se/~lindsey/JavaCourse/Book/Part1/Java/Chapter10/concurrencyTools.html]
I used a Future[] Array to make the code neater. So after that I submitted -and in this way filled up- the first 10 threads to the thread pool.
        int i = 9;
        while (i < 1000){
            for (int j = 0; j < 10; j++){
                if (futureArray[j].isDone() && i < 999){
                    try{
                        i++;
                        futureArray[j] = executor.submit(new Dock(i));
                    } catch (ExecutionException ex) {
                        ex.printStackTrace();
                    } catch (InterruptedException ex) {
                        ex.printStackTrace();
            try {
                Thread.sleep(100); // wait a while
            } catch(InterruptedException iex) { /* ignore */ }
        executor.shutdown();
        try {
            executor.awaitTermination(60, TimeUnit.SECONDS);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        executor.shutdownNow();
    }Each of the future[0-9] objects represents a thread in the thread pool. So essentially I'm check which of these 10 threads has been finished (using the java.util.concurrent.Future.isDone() method) and if yes I replenish that empty future[0-9] object with a new one.

Difference b/w Java Class and Bean class

hi,
can anybody please tell me the clear difference between ordinary java class and java Bean class. i know that bean is also a java class but i donno the exact difference between the both.
can anybody please do help me in understanding the concept behind the bean class.

Hi
Luckily in the java world the definition of components is a little
less severe than when using COM (I also have, and still occasionaly
do, worked in the COM world)
Firstly there are two definitions that need to be clarified and
separated: JavaBean and EnterpriseJavaBean (EJB)
EJB are the high end, enterprise level, support for distributed
component architectures. They are roughly equivalent to the use of MTS
components in the COM/ COM+ world. They can only run within an EJB
server and provide support, via the server, for functionality such as
object pooling, scalability, security, transactions etc. In order to
hook into this ability EJB have sets of interfaces that they are
required to support
JavaBeans are standard Java Classes that follow a set of rules:
a) Hava a public, no argument constructor
b) follow a naming patterns such that all accessor and modifier
functions begin with set/ get or is, e.g.
public void setAge( int x)
public int getAge()
The system can then use a mechanism known as 'reflection/
introspection' to determine the properties of a JavaBean, literally
interacting with the class file to find its method and constructor
signatures, in the example above the JavaBean would end with a single
property named 'age' and of type 'int' The system simply drops the
'set' 'get' or 'is' prefix, switches the first letter to lower case
and deduces the property type via the method definition.
Event support is handled in a similar manner, the system looks for
methods similar to
addFredListener(...)
addXXXListener
means the JavaBean supports Fred and XXX events, this information is
particularly useful for Visual builder tools
In addition there is the abiliity to define a "BeanInfo' class that
explicitly defines the above information giving the capability to hide
methods, change names etc. this can also be used in the case where you
cannot, for one reason or another, use the naming patterns.
Finally the JavaBean can optionally - though usually does - support
the Serializable interface to allow persistence of state.
As well as standard application programming, JavaBeans are regularly
used in the interaction between Servlets and JSP giving the java
developer the ability to ceate ojbect using standard java whilst the
JSP developer can potentially use JSP markup tags to interact in a
more property based mechanism. EJB are heaviliy used in Enterprise
application to allow the robust distribution of process

Difference between these Thunderbolt cables for an iMac?

What is the difference between these two Thunderbolt cables for connecting Thunderbolt harddrive docking station to an iMac?
http://store.apple.com/us/product/MD862ZM/A/apple-thunderbolt-cable-05-m
http://store.apple.com/us/product/MD861ZM/A/apple-thunderbolt-cable-20-m
Thanks!

Along the lines of this topic, does anyone know whether Mini DisplayPort cables are usable for Thunderbolt? Here's one, for example, that's cheaper than Apple's $29 cable:
http://www.amazon.com/exec/obidos/ASIN/B009NE77TQ/
I would be concerned about (at least) two things:
1. Can it handle the speed?
2. Does it have the right circuit?
It's possible that if it *seems* to work in a thunderbolt application, you might still run into trouble with intermittent data failure if it's not up to the task.
Thanks for any thoughts.

Difference among different pricing procedure

Hi,
I want to know that, what is the difference among different pricing procedure,Like
Standard,return,sample,scrap and credit memo.
Please reply soon.
Regards
prabudh

Hell tiwari,
<b>**Please Do reward if it helps**</b>
sales org + dist chan + div + document pric proc + cust pric proc --- > Pric Proc.
we determine the pric procedure. So, just have a different document pricing procedure for sales order document type and invoice document type. You can have a different pricing procedure with this change.
There are two simple reasons for making any Pricing Procedure in SAP SD Modules.
1) Business Reason. What are the pricing aspects or strategies you want to apply for the client requirement in order to sell their
goods or render services, is all about the reason for various pricing procedures.
Eg: Domestic sales pricing procedure,
- Export Pricing Procedure,
- A rebate pricing procedure or
- A High Discount oriented pricing Procedures.
- A repair pricing procedures.
You have your own conditions intended to few transactions only. Put all this conditions as a set defining your own Procedures. It may even include special requirements and formulas applied for such Pricing Procedures.
2) A special pricing procedures, in order to facilitate added functionalities of SAP pricing architecture, we must define new
pricing procedure. SAP Standard programmes checks these special Indicators in-order to do some required functions.
As a example 1, you need to have a Pricing procedure for condition supplement inorder to use the condition supplements. The condition supplement pricing procedure must be given in the condition type definitions (v/06) of the Pricing Condition where you need to supplement, without which SAP SD Condtion Supplements functionality doesnt work.
As a example 2, you need to have a Pricing procedure for Inter Company Billing Conditions(IV01 & IV02) inorder to be active for Inter Company Billing specific transactions. Thus make sure that, the procedure wouldnot apply for non-Inter company transactions.
Eg: KA0000 for Condition Supplement for KA00
- PR0000 for Condition Supplement for PR00
- ICAA01 for Inter-Company Billing
In V/08 of defining a new Pricing Procedure, in main screen, you have a field called TSPP (Transaction Specific Pricing Procedure). This has to be ticked on for Intercompany Billings.
The SAP help reads for this field as Under: Transaction-specific pricing procedure
Pricing procedure transaction-specific indicator
Before Release 4.0A, no special pricing procedures were used for intercompany billing and rebate credit memos, programs were just set accordingly to deal with these situations. As of Release 4.0A you are offered greater flexibility in the form of the option to define special pricing procedures for intercompany billing and rebate credit memos. For reasons of future compatability, you will still be able to use the old program specifications. For this reason, you must set this indicator if you want to create a special pricing procedure. This is to prevent the program settings being used.
This indicator is also used as of Release 4.0A to redetermine the condition class and the statistical condition indicator when copying from a reference document.
Example:
You copy prices from a shipment document to the billing document. The prices should lead to a surcharge in the billing document. This is guaranteed by the redetermination of the condition class in the pricing procedure.
Same case with Standard Pricing procedure or Inter Company Pricing Procedure.

What is difference among F5 and F6 and F7 in ABAP coding?

what is difference among F5 and F6 and F7 in ABAP coding ? Can u give me any example regarding this thread ?

Some additional info which can be quite helpful.
a watchpoint is an indicator in a program that tells the ABAP runtime processor to interrupt the program at a particular point. Unlike breakpoints, however, watchpoints are not activated until the contents of a specified field change. Watchpoints, like dynamic breakpoints, are user-specific, and so do not affect other users running the same program. You can only define watchpoints in the Debugger.
Use
You set watchpoints in the Debugger to monitor the contents of specific fields. They inform you when the value of a field changes. When the value changes, the Debugger interrupts the program.
Features
· You can set up to five watchpoints in a program.
See also Setting Watchpoints.
· You can also specify the conditions under which a watchpoint is to become active.
· You can specify a logical link for up to five (conditional) watchpoints.
See also Specifying Logical Links.
· You can define watchpoints as either local or global. If you define a global watchpoint, it is active in all called programs. Local watchpoints are only active in
the specified program.
· You can change and delete watchpoints.
See Changing Watchpoints
· You can use watchpoints to display changes to the references of strings, data and object references, and internal tables.
See Memory Monitoring with Watchpoints
Breakpoints
Apart from being able to execute an ABAP program in the Debugger, you can also start the Debugger call by the choosing a breakpoint. This is achieved by setting one or more of these breakpoints in the program. A breakpoint is a signal at a particular point in the program that tells the ABAP runtime processor to interrupt processing and start the Debugger. The Debugger is activated when the program reaches this point.
There is also a special kind of breakpoint called a watchpoint. When you use watchpoints, the Debugger is not activated until the contents of a particular field change. For more information, refer to the chapter Watchpoints.
Breakpoint Variants
The Debugger contains different breakpoint variants:
Static
A user-specific breakpoint is inserted in the source code as an ABAP statement using the keyword BREAK-POINT. A non user-specific breakpoint is set in the ABAP Editor using the BREAK user name statement.
Directly set
dynamic breakpoints
Can be set in the ABAP Editor or the Debugger by double-clicking a line, for example. Dynamic breakpoints are always user-specific, and are deleted when you log off from the R/3 System.
Breakpoints
at statements
The Debugger stops the program immediately before the specified statement is executed.
Breakpoints
at subroutines
The Debugger stops the program immediately before the specified subroutine is called.
Breakpoints at function modules
The Debugger stops the program immediately before the specified function module is called.
Breakpoints at methods
The Debugger stops the program immediately before the specified method is called.
Breakpoints at exceptions and system exceptions
The Debugger stops the program immediately after a system exception, that is, after a runtime error has been intercepted.
Static Breakpoints
Static breakpoints are always user-independent if there is no specification of a user name. Once a user has inserted the statement BREAK-POINT or BREAK name in an ABAP program, the system always interrupts the program at that point for that user or only for the user name. This procedure is only useful in the development phase of an application when program execution is always to be interrupted at the same place. For more information, refer to the chapter Static Breakpoints.
In HTTP sessions, a static breakpoint is skipped if you did not set additional dynamic HTTP breakpoints in the editor of a BSP page. Instead, a corresponding system log entry is written, which can be checked using transaction SM21.
Dynamic Breakpoints
Dynamic breakpoints are user-specific. Therefore, you should use them if you only want the program to be interrupted when you run it yourself, not when it is being executed by other users. All dynamic breakpoints are deleted when you log off from the R/3 System.
Dynamic breakpoints are more flexible than static breakpoints because you can deactivate or delete them at runtime. They have the following advantages:
· You do not have to change the program code.
· You can set them even when the program is locked by another programmer.
· You can define a counter that only activates the breakpoint after it has been reached.
Special dynamic breakpoints are useful when you want to interrupt a program directly before a particular ABAP statement, a subroutine, or an event, but do not know exactly where to find it in the source code. Event here is used to refer to the occurrence of a particular statement, for example, or calling up a method. Special dynamic breakpoints are user-specific. You can only set them in the Debugger. For more information, refer to the chapter Dynamic Breakpoints.
In HTTP sessions, the system stops both at static and dynamic breakpoints if a dynamic breakpoint was set in the editor of a BSP page before program execution.
Lifetime and Transfer of Breakpoints
A static breakpoint remains intact as long as the BREAK-POINT or BREAK-POINT name statement is not removed from the source code. Without saving, dynamic breakpoints only remain intact in the relevant internal session. However, they remain in effect during the entire user session if they are saved by choosing the menu path Breakpoints ® Save in the ABAP Debugger. For more details on the subject of user sessions and modes, refer to Modularization Techniques in the ABAP keyword documentation.
If you call an HTTP session during a user session, only the HTTP breakpoints are loaded when the HTTP session is started. You activate HTTP debugging in the ABAP Editor by choosing Utilities ® Settings ® HTTP Debugging. Depending on the setting, the system then displays either the HTTP or standard breakpoints in the Editor.
If you call an update session during a user session, breakpoints that were defined beforehand in the calling processing unit are copied to the new update session, where they can be displayed under Breakpoints. If, in the ABAP Debugger, you check Update Debugging under Settings and then, for example, call the update module func using CALL FUNCTION func IN UPDATE TASK, a new window is opened in which you can debug this function module in the update session. All the breakpoints that were set in the calling processing unit can also be processed here.
we can keep them at :
Statements
Subroutines
Function Module Calls
at Methods
System Exceptions
break point :
we can start debugging from that point or if we keep break point at some place we can directly got ot htat point using f6.
watch point: for example if we have to check the output for 4000 records based on a field value i.e.for vendor number 'in'we have to check then we will create watchpoint on field LIFNR value '2000'. then we can directly go to vendor whose numbe ris 2000
