Using servlets for custom protocol???

Is it possible to use servlets for my own custom protocol??
Can somebody PLEASE say yes or no!!!!
I've been struggling with this for hours!
Is there an easier way?

Yes, I searched through the API docs, doesn't tell me anything. I need proven examples.
There's nothing out there .... strange!!!Actually, not so strange.
I think the original design of the servlet API permitted protocols other that HTTP, but in practice it was found that it didn't work as well. I think I've heard of an FTPServlet subclass, but that's it.

[b]can I use servlets for Chat? new to servlets[/b]

I want to a chat application for someprof and students
I am using multicasting technique to send and receive messages
I used applets and created it but applets don't support java.net's MulticastSocket so I used certificate
Now I want to use servlets for this in JSP because I called applets from JSP
Can it be possible? If yes please clearify.

it is possible
you could create a jsp page that would update like 10 or 20 or whatever number of ServletContext attributes.
in the jsp_service or in the doPost or doGet method of a servlet:
String messageFromUser=request.getParameter("msg");
int num=15;
String[] chat=new String[num];
chat[0]=getServletContext().setAttribute("chatLine" + 0, messageFromUser);
for(int i=1; i<num; i++) {
String previousMessage=getServletContext().getAttribute("chatLine" + (i-1));
chat=getServletContext().setAttribute("chatLine" + i, previousMessage);
out.println(chat[i]);
however, there is a pretty decent client/server chat program that can run as an applet here:

Using nullLayout for custom component

I am writing an AccordianPanel as a custom component that can be dropped into a JPanel and behave as expected. I am using a null layout in the outer container (JPanel) as the accordian dividers need to move as told and not be managed by a layout manager. When I resize a window or another container that the custom component sits in, it doesn't resize anything - I understand this is the behavior I would expect as that is how I coded it.
Now, I want to have the custom component resize its internal stuff when the container it resides in (i.e. JFrame or most likely another JPanel) gets moved, but I don't know how to do this. The outer most component in my custom components hierarchy is a JPanel whose layout is set to null and I stuff everything else inside there.
I believe I need to add a componentListener to my JPanel whose layout is set to null, but I am not sure. Could someone send me in the right direction.
thanks

the best approach might be to implement your own LayoutManager (which is simple enough) and use it rather than absolute positioning....
If you read postings in the forum you will find most people recommend using LayoutManagers and not a null layout so you don't have problems like this.Hello sarcommand , camickr, and anyone interested,
I've tried to bring this discussion up again just a few days ago, and was disappointed I got no feedback - must be a dull read :o(
Here is the [link to the thread|http://forums.sun.com/thread.jspa?messageID=10723670&#10723670], would you mind having an eye on it?
I'm sorry to hijack this thread (seems slightly less rude than bumping my own former thread up), but I've read several discussions on this subject too, and still I can't decide whether I should follow the CustomLayoutmanager track.
Although most of the writing there is specific to my current problem, it highlights 3 points I think are general enough:
- A custom layout (whatever the way it is implemented, I discuss 4 approaches in the thread) is generally used to display custom components, or at least, components that represent custom application-specific entities or input points. -> Is is worth the trouble to abstract the positioning logic when this "custom layout" has only one, at best two, use cases (a couple of specific screens in your specific app that represents your specific entities)?
- A custom (app-specific) layout manager is likely to require more knowledge about the things being layed out than the default min/max/pref sizes. In particular it may require to know data of the underlying model objects represented by the children components. How is that best designed? I tentatively think it's by way of custom Constraint classes which have to be abstract enough yet should be easily mapped from the app-specific data.
- The CustomLayoutManager integrates natively with regular graphical events (hiding, resizing,...), but how to integrate app-specific events (such as, when the underlying data change in such a way that should be reflected by a change in the layout, how/when to force the re-layout)?
Thank you for your help.

Using RFBIDE00 for customer master upload

Hi all,
   Does any one used batch input program RFBIDE00 for Customer master Upload data in to SAP.
   Could you please explain how to use it... its urgent, appreciare if your early reply..
   I am planing to use it through Run the program from SE38..
Thanks..

hi good sap1,
Batch Input - Customer Master Data (RFBIDE00)
Description
All new fields for customer master records can be transferred to the R/3 System also with the report RFBIDE00.
Furthermore, the batch input can be carried out with the existing record definitions. By means of the end of record marker, the report recognizes which record structures do not yet correspond to the extended record layout and initializes the new fields with NODATA.
It is pointed out in the batch log, which structures are yet to be maintained. This should be done as soon as possible to be able to use the new functions or fields
Introduction
It is now possible to pass the information concerning tax categories and withholding types (for the extended withholding functionality) and the special Argentine fields via the standard batch-input program. Please look at the standard documentation if you need further information on the program.
Additional Fields
The additional fields have been added to the structures BKNA1 (general information) and BKNB1 (company code data). Please use transaction SE12 to see the fields of the structures.
Enrichments for Tax Categories
The following table shows how to fill the interface table BKNAT to pass the tax category data:

Using DAC for custom Environment

Hi All,
I would like to know that, can we use DAC to schedule , run the loads for custom ETL environment(not BI APPS), does DACt supports. Below is is my set up
-Oracle 11g DB(source and target )
-Informatica 9 installed
-Mappings, workflows are developed
-DAC 11g is installed
Now I want to set up DAC so that I can run loads from DAC instead of Informatica. Please any let me know high level steps. Is it different from BI APPS environmen if so kindly let me know configuration
Thanks in advance

Short answer is NO...as per licensing agreements, you can only use DAC and OBIA to load a OBIA DW target.
pls mark correct

Query: Predictive Use Cases for Customer Acquisition during Launch Phase

Dear all,
May I ask you to help me with some Predictive Use Cases (essentially SAP InfiniteInsight) for a Telco Customer who is going to launch new 4G services.
Some important points to note are:
1) Being a new product launch, there is no historical data about customers.
2) Predictive use cases should help the customer acquire more customers (higher acquisition rates)
This means that the traditional churn, next best activity, product recommendations scenarios would not be a great fit because they would essentially be coming in the grow phase.
Additional info: The customers has other businesses in retails, mining, refinery.
Rg,

Servlets implementing custom protocol in WLS 6.1

          Hi.
          Does WLS 6.1 support other than HTTP/S protocols with servlets? If it does, how
          requests are dispatched to a servlet implementing a custom procotol.

No, I don't think it does. You'll have to implement it yourself.

Using SPAU for custom development

Hi Guys,
take the following szenario:
We have Development system A and a copy of this system Development system B. Where B is the project system. In the time the systems A and B will be enhanced using different development. At one point in time the developments from system B should be merged with system A. Could this merge be done using some similar functionality like the SPAU after SAP-Upgrade to ensure the developments with origin in A and developments with origin in B are compared and amended in the right way ?
Thanks for any idea in managing this.
Best regards,
André

ok a small excourse on SPAU.
When transporting a transport request into the system (same for hot-packages or release-change), a new version is beeing put into the version managment of the referred object.
SPAU compares the active versions with the ones which got transported.
Problem at this edge is that SPAU just scans for modifications.
Modifications are changes to SAP-Standard objects. SPAU just checks for differences in SAP object.
Objects in customer name room, x or y will be ignored.
Thats why i dont think you can use SPAU.
BUT well you could copy the SPAU, and then reprogramm it a way it will not ignore x and y objects.
When SPAU is done and all is fine, THEN you transport the things to test and productive Server.

Using Servlet for non HTTP purpose

Hi,
I have a requirement where I require tomcat to serve a non http request. Is there a way?

The HTTP protocol begins with a line like:
GET /some/thing HTTP/1.0
Tomcat uses the "/some/thing" to find out to which servlet to give the request.
If your protocol doesn't have that line, Tomcat is going to have a hard time knowing what to do with the request.
You could write a thread that opens a ServerSocket, accepts incoming requests, and hands them off to a servlet-like system (perhaps even subclasses of Servlet). You could even run that thread within Tomcat. If you want/can restrict yourself to Tomcat, you may even be able to use parts of Tomcat's internals (the Service/Connector/Engine infrastructure or whatnot.) Whether this is a good approach depends on all kinds of details.

How to use Cache Management Library (CML) for custom applications?

Hello,
We are planning the migration of multiple applications (J2EE, Portal, Web-Dynpro for Java) from 7.01 to 7.3 and we would like to replace some custom cache implementations with a central cache management provided by the SAP Web-AS Java.
Several SAP standard services (e.g. UME, Configuration Manager, Scheduler) seems to use the "Cache Management Library" (CML):
[http://help.sap.com/saphelp_nw73/helpdata/en/4a/f833eb306628d2e10000000a42189b/frameset.htm]
Such caches can be monitored using SAP Management Console (AS Java Caches).
Portal Runtime (cache_type=CML) and Web Page Composer can also be configured to use CML:
[http://help.sap.com/saphelp_nw73/helpdata/en/49/d822a779cf0e80e10000000a42189b/frameset.htm]
[http://help.sap.com/saphelp_nw70ehp2ru/helpdata/en/13/76db395a3140fcb17b8d24f5966766/frameset.htm]
So our questions:
How to use CML for custom applications?
Is there any example or documentation available?
Kind Regards,
Dirk

Do not use tpc 2106T for custom animation Purpose

I was trying to use TPC2106T for developing a MMI for an application.To my surprise the Labview in built functions for creating custom animations (eg ring control) does not work for TPC2106T .I had been told this is to do with Windows CE OS (which is installed in TPC)
So please be careful if you want to use TPC2106T for custom made animation as you might suffer like me.I am using labview 8

Feasability using OPC for COMPLETE PLC IO-NO LADDER LOGIC

Attention intergration Gurus:
I was wondering if this is REALLY feasable and would work? We need a high channel output using AB PLC's for air solenoids (high current) and +24v Prox's and such.
I really would like to get rid of the existing (3 plc) design and use labview to do everything.
The PLC's inter-communicate via RS232, done by three seperate companies. Thats why its not intergrated.
Has anyone really used PLC's I/O withou a Ladder program ??
I can do both, but want to bring things up to todays tech....
Thanks
Eric

I do this frequently, although not with OPC. Usually we use NI's cFP-180x I/O modules, but we've also non-NI hardware.
The basic questions you would want to ask yourself:
Can I afford a situation where the system might not behave correctly (for example, if there is a network error or the desktop machine gets stuck doing something else)?
Is the technology I'm going to use (OPC, Modbus, custom protocol, etc.) going to be fast enough for the balance of the desired program speed and the channel count?
If the answer to both of those is yes, then you should be able to do this.
Try to take over the world!
