Diff between Java,Window and HTML Clients

Hi can any body clear me
what is the difference between
1. JAVA Client
2. Windows Client
3. HTML Client.
regards
mmukesh

The Windows client requires SAPGUI for Windows loaded on the dekstop (400+ MB of disk), but it works most efficiently.
The HTML client requires an ITS and is not as efficient, but need no specialized software on the desktop.
The Java client is almost never used except by Mac and Unix users!
Cheers
try searching SDN for SAPGUI variants for more details

What exactly is the diff between main window and variable window

what exactly is the diff between main window and variable window in SAP script?

hi,
MAIN WINDOW :- In a main window you display text and data, which can cover several pages (flow text). As soon as a main window is completely filled with text and data, the system continues displaying the text in the main window of the next page. It automatically triggers the page break.
You can define only have one window in a form as main window.
The main window must have the same width on each page, but can differ in height.
A page without main window must not call itself as next page, since this would trigger an endless loop. In such a case, the system automatically terminates after three pages.
VARIABLE WINDOW :- The contents of variable windows is processed again for each page, on which the window appears. The system outputs only as much text as fits into the window. Text exceeding the window size is truncated; the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different form pages.
As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike. The only difference is that constant windows have the same size throughout the form.
hope this will be useful.
If useful then reward points.

Syed

Managing stream between java server and c client

Hi all
I'm working on a client/server application.
Client have been written in C
Server is in Java.
The client connect to the server, send a message (unknown size) and wait a response from the server.
The server on connection start a new thread. This thread try to read data from the socket, using a BufferedInputStream :
BufferedInputStream in = new BufferedInputStream(socket.getInputStream());
As far as I dont know the size of the incoming message, i use the folowing algorythme to read data :
    byte[] bytesLus = new byte[1000];
    byte[] tmpBytesLus;
    byte[] tousLesBytes;int nb;
    i = 0;
    tousLesBytes = new byte[0];
    Log.trace(sourceTag,"Lecture des premiers octets");
    nb=in.read(bytesLus,0,bytesLus.length);
    Log.trace(sourceTag,nb+"octets lus");
    while (nb>0){
        tmpBytesLus = new byte[i+nb];
        System.arraycopy(tousLesBytes,0,tmpBytesLus,0,tousLesBytes.length);
        System.arraycopy(bytesLus,0,tmpBytesLus,tousLesBytes.length,nb);
        tousLesBytes = tmpBytesLus;
        i = i+nb;
        bytesLus = new byte[1000];
        Log.trace(sourceTag,"nb octets lus : " + i);
        if (in.available()>0)
            nb=in.read(bytesLus,0,bytesLus.length);
        else
            nb=0;
This seemed (but only seemed - i will explain it later) to work fine :
the client send a 6300 bytes sized msg. Server receive it, treat it and send response back. and this at each try.
But when i change the log level of the server from TRACE to ERROR (wich have on consequence to accelerate the instruction Log.trace( ... ) the server doesn't work so fine !
On first try, everything is ok, but on second, client send the same 6300 bytes msg, but server consider receiving only 3000 !
After debbuging, i found why :
the reason is the use of :
if (in.available()>0)
If you are reading faster than the writer, there is a moment where the stream is in a blocking state for the reader. and in.available return the number of bytes you can read before blocking...
So my server consider that it reached the end of the message....
So, after this long introduction, here my question :
What is the best way to detect the end of a stream ?
Should I send a special character on the stream and decode it on server ?
Thank's for your advice.
Olivier

Generally, there are n ways of making sure an entire message of unknown size is recieved:
1. Include some kind of validation criteria at the beginning of the message : checksum, bytecount, etc.
2. Format the message such that the server can tell when the end is reached (subject to "line noise" problems)
3. Enable two-way communication between the client and server, so they can work it out as they go.
4. Use a pre-established protocol that handles all this for you
5. Close the stream after writing if you only have one message.
6. etc etc etc.

In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

hello all
In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

Hi Swamy,
The differences between IDoc and BAPI are as follows:
IDOC
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system.
Idocs are processed asynchronously and no information whatsoever is returned to the client.
The target system need not be always online. The IDOC would be created and would send the IDOC once the target system is available (tRFC concept). Hence supports guaranteed delivery.
With asynchronous links the sub-process on the client can be finished even if the communication line or the server is not available. In this case the message is stored in the database and the communication can be done later.
The disadvantage of asynchronous links is that the sub-process on the server cannot return information to the calling sub-process on the client. A special way for sending information back to the client is required. In addition, a special error handling mechanism is required to handle errors on the receiving side.
IDOCs may be more changeable from release to release.
IDOCs are poorly documented.
BAPI
BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
BAPIs are called synchronously and (usually) return information.
For BAPIs the client code needs to do the appropriate error handling.
Problems with synchronous links occur if the communication line or the server is temporarily not available. If this happens, the sub-process on the client cannot be finished (otherwise there would be data inconsistencies).
Synchronous links have the advantage that the sub-process on the server can return values to the sub-process on the client that has started the link.
BAPIs are not totally immune to upgrades.
BAPIs are reasonably well documented.
Reward points if useful.

Sekhar

Diff between sap query and abap query

diff between sap query and abap query

Hi,
ABAP query is mostly used by functional consultants.
SAP Query :
Purpose
The SAP Query application is used to create lists not already contained in the SAP standard system. It has been designed for users with little or no knowledge of the SAP programming language ABAP. SAP Query offers users a broad range of ways to define reporting programs and create different types of reports such as basic lists, statistics, and ranked lists.
Features
SAP Query's range of functions corresponds to the classical reporting functions available in the system. Requirements in this area such as list, statistic, or ranked list creation can be met using queries.
All the data required by users for their lists can be selected from any SAP table created by the customer.
To define a report, you first have to enter individual texts, such as titles, and select the fields and options which determine the report layout. Then you can edit list display in WYSIWYG mode whenever you want using drag and drop and the other toolbox functions available.
ABAP Query,:
As far as I Believe, is the use of select statements in the ABAP Programming. This needs a knowledge of Open SQL commands like Select,UPdtae, Modify etc. This has to be done only by someone who has a little bit of ABAP experience.
To sum up, SAP queries are readymade programs given by SAP, which the user can use making slight modification like the slection texts, the tables from which the data is to be retrieved and the format in which the data is to be displayed.ABAP queries become imperative when there is no such SAP query existing and also when there is a lot of customizing involved to use a SAP Query directly
use either SQ02 ans SQ01
or SQVI tr code

Selecting between java.io and java.nio

Hi,
I'm a bit confused between java.io and java.nio. What sre the major differences between these two?
In areas are these best applicable?

The java.nio package improves on the basic Java I/O that was available prior to JDK 1.4.
It is designed to interoperate more natively with the underlying file handles (sockets, open files etc) to achieve better performance.
The improvements include true non-blocking I/O, better buffer management, character-set support, channels (similar to Occam's channels) and selectors, and some other ancillery stuff. Most of these classes are designed to be inherently threadsafe.
There are some examples here:
http://java.sun.com/j2se/1.4.2/docs/guide/nio/example/index.html
However, if you are still a beginner with file or network I/O, its better if you start with the simple I/O first. You'll appreciate the NIO improvements better afterwards.

There are so many differences between the version in different objects
I will explain in two or more objects the difference
1 in the customer master in 4.6 version there is no partner function tab in the customer in xd01 t-code
and also there is no CIN tab in that version
but it is there in the 4.7 EE version
This is the major change from the 4.6cc to 4.7EE
2. in 4.7EE there is some settings that are related for CIN
which cannot be done in 4.7EE that means they need some patches for doing the configuration setting for the CIN
But we can do the same in the 6.0 version
These are the some of the settings that are differed in the two versions and in that two objects

Basically an application server has more functionality than a webserver, such as enterprise javabeans. That is assuming we are taking about a java webserver like Tomcat.

Whats is difference between Java JRE and Java SDK

Hi,
what is the difference between Java JRE and Java SDK...
i think both of them have the same set of files to be installed...
I am not able to understand where they differ

The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.

Compatibility between Java crypto and open ssl

Hello
I have some question about compatibility between java crypto and openssl library.
This is my case:
1.I created DESede key and stored it to file:
SecretKey key = KeyGenerator.getInstance("TripleDES").generateKey();
File f = new File("c:\\key.dat");
DataOutputStream dos =new DataOutputStream(new FileOutputStream(f));
dos.write(key.getEncoded());
dos3.close();2.I encrypt some file "c:\\normal.dat" through:
ecipher.init(Cipher.ENCRYPT_MODE, key2);
byte[] enc = ecipher.doFinal(normalData);
File f2 = new File("c:\\enc.dat");
DataOutputStream dos =new DataOutputStream(new FileOutputStream(f2));
dos.write(enc);
dos.close();

You have carefully left out some critical java code, namely the Cipher.getInstance() method. You'll notice in the documentation for this method that there 3 components to the "transform" argument of this method, the algorithm, the mode, and the padding. All of these must match exactly with the what openssl is using. Furthermore, if you are using one of the modes which require an IV, like CBC mode, then this must match exactly too. If you don't explicitly specify some of these parameters, you might get default values supplied. It is up to you to find out what these are.

What's the difference between Java SDK and the Enterprise Edition?

What's the difference between Java SDK and the Enterprise Edition? Are they both free?

both r free but they are used in diffrent applications. sdk are used for simple apps that run on your computer while j2e (enterprise edition) are ment for large distributed computer systems that include servers and such. if you don't know the diffrence you probably wont need the the j2e, only the sdk.

Diff between Seeburger Adapter and File Adapter

Hi All,
My company needs to interact with some banks and the banks are particular that they want SFTP, which is not supported by File Adapter, so we have decided to go with Seeburger adapter.
Now what are the differences between File adapter and seeburger adapter?
I believe that Seeburger adapter does not support File Content Conversion, Archiving etc.
Could you all pls put some light on the diff between file adapter and seeburger adapter when it comes to dealing with files?
Xier

Hi
You are aware with working of File Adapter.
The most direct way of using the Seeburger adaptors is to configure the BIC as a module. There is a software component from seeburger called bicmapper which will allow you to
1. Define or import the inbound message metadefinition in various formats ( edifact, xml,...)
2. Using a mapping create an xml variant as the output metadefinition or edifact in the other direction.
3. Create a one to one mapping between input en output.
4. Export the metadata in xsd or sda format for import in XI
5. Generate an SDA which can be deployed in XI and used as a module.
