ERP (Abap) to NW (Java)-Communication with JCA (inbound) in EJB

Hello,
i found examples which use JCA for outbound-communication from java-ejbs to an abap-system. but i didn't found much about how to implement inbound-communication. So i want to call an java-ejb on my NWCE 7.1 (JCA 1.5) from an Abap-System.
Has anybody more information or code snippets how to achive this?
thx and regards
Matthias

Need API for Java communicating with RS232

Dear All,
I am a newbie to Java. I have a sensor connected to a microcontroller, and this microcontroller is also connected to a PC through the RS232 (COM 1). I have installed the Java Communications API "Javax.comm" on my PC and was able to run the "BlackBox" sample program. What I require is a simple Java program that will read and show the bytes comming through the COM1 port. If anyone has done anything similar or has an idea of how to go about it, could they please send me some example code, I would be very grateful. Or if anyone knows about any website with such similar examples i would be very grateful.
Thank you very much.

Java Communications API (JCA) is really that difficult???

Hi everyone, I am an advanced developer for some years in Microsoft Platforms (.NET, VS6, etc.). I have used Microsoft Programs for a while and I can certainly say that I can develop serious programs.
The reason I am posting this is that I am doing some reaserac in the usability of other programmer platforms for windows and linux.
I turned towards Java about a month ago. I kno very well the structure of the language but I came across something very silly:
I tried to install the javax.comm package! Ha ha ha...
I thought SUN is a serious company (one o the largest) and I keep wondering why this package is so difficult to install. I tried every single post on the forums and nothing worked for me. I am using sdk1.4.1
with SUN Studio One update 1 (formerly Forte, ha ha).
IS THERE ANYONE OUT THERE THAT HAS THE API WORKING ON A WINDOWS 2000 PLATFORM (language doesn't matter but the answer -please- must be in english...) THAT CAN GIVE ME THE MAP OF FILES LIKE:
c:\j2sdk1.4.1\bin\win32comm.dl
c:\j2sdk1.4.1\lib\javax.comm.properties
c:\j2sdk1.4.1\lib\ext\javax.comm
c:\program files\java\j2re1.4.1\lib\javax.comm
Classpath = <somthing>
etc.
Please, I can't get this working. I need to see the damn package in the Studio so that I can work properly..
CAN THIS API ORK WITH THE STANDARD EDITION OF JAVA AND THE COMMUNITY EDITION OF FORTE???

Hi,
Acneto, the jar file must be mounted and the
the parser must be updated. If the api is installed
correctly (finally i have it running) then the ide is
able to compile and run programs that are associated
with the api.That's what I've told you before...I've installed the commAPI in windows 98, Me, 2000 and XP...
The problem with installing the API (I haven't told you before because I thought you already done it...) is with the "java home". Lots of people think that their java home is the jdk\lib and may be the c:\windows\java\lib...or other. And other people think that their java home is c:\windows\java\lib and then discover that is \jdk\lib.
So what I always advice is to make a little problem:
class JavaHome
System.out.println("My java home is:"+System.getProperty("java.home"));
}And so copy the files in the wrong place...
(I don't know if there is a different way to update
the parser database without adding the jar to the
filesystem).I don't think so...anyway, you can mount the jar, update the database, and then unmount!
I will make a post today that indicates a way of
installing the api succesfully under win2K pro with
j2sdk1.4.1 and Sun Studio One update 1 IDE.
By the way, I believe that a special forum regarding
serial and parallel port communications should be
launced by SUN. There are just too many ppl out there
that make such applications.I agree with you!
Best regards,
ANeto

Java communication with applets

Hi, I'm new so I hope this is where I should post this question.
Basically, I want to write a java program that communicates with an applet and retrieves data from the applet. The applet is executed from secure http protocol and connects via the socket port. I know the applet is MainClassApplet.class, but I do not know any of its methods, variables, constructors, etc.
Is it possible to communicate with this applet and retrieve information from it?

The jar file is just a resource on the web server,
like the web page that it's called from. You could
use your browser to grab the jar file. Or use
something like curl.hmm.. do you know of some code or tutorial I could
look at for this?Look at the HTML source of the web page that includes the applet. From that page's URL, and the <applet> or <embed> or <object> tag that refers to the applet, figure out the URL to the jar file. Then type that URL in the location bar of your browser.
Or get "curl", which is a command-line utility that acts like a browser, and use that to get the file. Read the curl help pages.
User name and password doesn't necessarily have
anything to do with HTTPS. Is the site also using
HTTP authentication, or what? How do you know it
wants your user ID and password?Well, why would they make you pay for an account if
people could easily access their webpages? Sometimes a site will password-protect some pages but not others. And anyway, are they asking for a user name and password or aren't they?
I just
know it uses a post method in order to retrieve a
user's account name and password.. I don't think it
uses HTTP authentication.. It has 4 parameters that
it uses to execute the post method.Well, that tells me almost nothing.
Before trying to grab and reverse-engineer some functionality from a site, probably in a manner that violates whatever agreement you agreed to when you signed up for the site, you might want to learn about basic web technologies, like HTML, HTTP, etc. Then learn basic Java.

UME java mapping with ABAP

Hi Experts
I need to keep the users of my AS Java syncronized with some user in ERP.
Thats means, when some user change some information in ABAP, i need to get this information and change in AS Java too, like email or password...
I can't use CUA, and i can't use that function that syncronized ABAP user in AS Java automatically. There is another way to do it?
Could somene help me?
Best Regards
Marcos Brandã

Hi Martin
Thanks for your response,
When i was talking about the function that syncronized the user in abap and java, i was talking exactly about use ABAP user store as a source for UME. This solution doesn't wirk because the customer do not when activate this. He is worried about the performance and the information of the user in 2 diferent location, there is a lot of users in ABAP user store and he don't want this solution.
I need to get just specific user to reply in Java stack user store. I kown how can i do it without get user password, but this do not resolve to me. I need the same user credencials in both systems.
I will see th SPML / Idm and what kind of problems this solution brings to me, if this solve my problem, i will try to use it.
There is another way, instead this two way? maybe get the encripted password, decript it and save in java user store with encription mecanism of ume?

Need help with ABAP coding using java

Dear experts,
I have used ABAP to code many reports/function modules.However as i know java quite well,i want to achieve the same using java.I have utilized JCO to retrieve information from RFC in this mission.
However i realized that i had to code all things using ABAP and use java only as interface to connect to
SAP fetch that module and display information on console.It was not that fun.
I want that i should not Login to SAP but work only using java.
I heard SAP Netweaver is a good choice.But i dont know much about it.Will i be able to develop reports only by java and how ?
Plz suggest.

hi,
I hope that you already have the J2ME Toolkit and that your emulator works okay. In the toolkit you get several examples to show you how to program a MIDlet. One has to do with a HTTP client server connection. Also in the API documentation for the J2ME there is a Connector class that you used to set up this communication and in the description of this class it pretty thoroughly explains how to set up an HTTP protocol client.
However, if you want to do some other kind of networking then you are pretty much out of luck, as the TCPIP socket protocol has not been fully implemented and is optional to the J2ME specifications, only the HTTP protocol is certain to be available. This means that mobile phone companies can add other networking functionality to their phone's java virtual machine if they feel like it. This is a bummer I know.
I hope this helps.
Cheers,
Mark

Sir i am using datasocket read ,i am communicating with java but my problem is that bcz im using while loop to see if value has changed my labview consumes all the processors time ,sir i want a event like thing so that while loop is not in continuous loop

sir i am using datasocket read ,i am communicating with java but my problem is that bcz im using while loop to see if value has changed my labview consumes all the processors time ,sir i want a event like thing so that while loop is not in continuous loopHi Sam,
I want to pass along a couple of tips that will get you more and better response on this list.
1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
4) If you have a question first search the examples for something tha
t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"

Problem with Java Communication API

hi
I installed the Java Communication API on win32 platform (as per the guidelines)
Now when I try to run the sample program 'Blackbox' for the serial port, I get an error (in fact an exception is generated inside main function in BlackBox.class file)
I tried the SimpleRead.java example but that too generated the same exception
Can anybody help me out.... I am a novice with Java Comm API

I tried running the sample BlackBox program provided for serial port and now it says
No Serial Ports Found!
I verified that both comm.jar and javax.comm.properties are in the <JDK>\lib directory.
Actually, I am using netBeans IDE 1.4 and I used the C:\J2SDK folder installed with netBeans for the Java Communicaion API
plz help.

VB Client communicating with a Java servlet

Hi,
I have a java servlet and I would like to have a VB application communicating with the servlet.
Can I do it ? and if yes, how to do it.
Thanks in anticipation,
Ayana

The VB client can open an internet or Http connection to the servelet, send a request and parse the response. We've done it here but I don't know exactly which ActiveX control the VB guy uses.
Also look into using webservices.

Servlet Communication with Java WebStart

Hi there,
we have an application that works fine with Java WebStart whenever we start it in a local area network. But from outside the LAN the application cannot communicate to it's servlets. I use the codebase IP address with the servlet runner's port (http://<codebase IP>:port/) as URL for servlet communication, but the application's request never reaches the servlets.
My question is now, if anyone had the same or a similar problem with servlet communication using Java WebStart, or if anyone knows, if that might be a problem with proxy configuration.
The servlet runner we use, is JServ from Sun (JSDK2.0) and the webserver where it is running on is not behind a firewall or a proxy, but the client PC with the web start application is.
Thanks,
Katja

Thank you for your early reply. But I think, that's not the problem.
I get no security error and the webserver is identified the same way it is in the jnlp file. Also my application is not running in the Sandbox. My assumption is, that the http-request to the servlet does not go through the proxy server between my PC and the PC the servletrunner is running on.
I wonder if I have to configure my application to use a proxy server for communication with the servlets instead of the direct http-request to the servlet runner?

Java interface with xml communication

Hello everybody,
For a project i need to make a java interface with xml communication.
For example ; from 1 laptop I press on a java button and then i need to get a text message on the other laptop.
The java interface is already created now the xml code for communication.
I hope someone can help me how to start with the xml code.
Are there any templates that i can use?

I need to use XML for this, cause it is in the
assignment.As far as communication is concerned, it doesn't matter that you are sending XML. You can send any kind of data. So first find out how to send data, then send data which is XML.
I only want to know if its possible to send data/text
from 1 laptop (windowsxp prof) to the other laptop
(also windows xp prof).Provided the other laptop is running a server that can receive that data.
Maybe its easier if I send data to a specific IP
address?Provided there is a server running at that IP address that can receive that data. You can use an IP address to connect to a server but that has nothing to do with sending the data.
Its important that the communication between 2 system
is in XML language.XML is not a programming language. XML is a format for storing data. You can certainly send XML-formatted data between two computers.
So i hope u have a solution for my problem.The solution would be for you to learn how communication between two computers works in the real world. If you have an assignment that says you have to make communication work, surely there was something taught to you before about how to do it?
