Connect Java programs to ABAP generated Web Services

Hi everybody again!
This time I write looking for code examples about connecting my java programs in Netweaver to Abap generated web services.
Could anyone send me any example, please?
Thanks in advance again!
Alberto.

Hi,
I'm also looking for code examples about connecting Java programs to ABAP generated Webservices... could you, please, send it to me ?
actually, I need to call bapi from a java Web site.
(as an SOAP request ...)
is it better to <b>generate webser</b>vices from the Bapi then call it,
Or shall i keep the Bapi, and call it from a java webservices based on <b>JCO/RFC</b> calls ...
what's more efficient ?
java webservices + Jco calls to the bapi ?
or direct calls to generated abap webservices ?
thanks

Need help connecting java-program to Clarion-software/database

I have made a simple java-program which monitors control-lines in a computers com-port. Now I need to pass this information to Clarion-based software.
I am currently writing the changes in to a file from which the clarion software will read the changes, but is there any better way to do this?

Check out these websites:
- http://www.softvelocity.com
- http://en.wikipedia.org/wiki/Clarion_programming_language
The problems is actually the fact that i don't have access to this clarion-based software or it's APIs etc.

Connecting Java programs to Internet

How do we allow two users running the same Java program communicate over the internet via the same Java program ??
For instance, if I were to make a two player game like tic-tac-toe, how would I make the changes one player makes appear over the computer of other ?
[PS - About the tic tac toe game, is there an open source available anywhere ? ]

Probably the simplest is a pier-to-pier socket setup. You just have to define your own simple "top-level network protocol".
>
[PS - About the tic tac toe game, is there an open source available anywhere ? ]Why of course there is. Is google broken or something? Hint: Keep looking past the first page... and/or search these forums. Look right, see the search box?
If you wanted to get really funky I suppose you could even do it pure ECMA version using ajax'y sockets to talk page-to-page... but that's not java, and you asked about java.
So... Start here... go through the Sun tutorial... and then I suggest you dig for IBM's chat-app tutorial (sign up for it, it's worth it)... then you need to write a single swing tic-tac-toe (again search these forums, or google it)... then you get to figure out how to merge in the comms-stuff with the swing stuff... which will almost inevitably lead you to MVC (google again) to "drive" the UI's from the protocol.

Newbie : Complete Connect java program to DB2

Dear all,
I am failry versed with java and jdbc. I did a lot of google and searched a lot of forums but no one gave me all the details. I have done a lot of oracle jdbc. I would appreciate if some one could give me all the details please. I dont even know which jar files should be in the classpath.
Oracle Comparision :
place ojdb14.jar in classpath
        Class.forName("oracle.jdbc.driver.OracleDriver");
        // Create a connection to the database
        String serverName = "127.0.0.1";
        String portNumber = "1521";
        String sid = "oracle";
        String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;

        // Create a result set containing all data from my_table
        Statement stmt = connection.createStatement();
        ResultSet rs = stmt.executeQuery("SELECT * FROM sometable");
    I am just about clueless on db2 .. (was able to scape through the install and the install is fine.).... to the limit that I hope my db2 is running on port 50000.
TIA

How do I establish a connection to another Java program on the net?

Hi all,
I have been reading the java tutorial to find a solution to my problem but I havent really found what Im looking for.
I want to establish a connection that allows a client to get a copy of an object from a running java-application on a server on the internet.
I have read about the Socket-class but the tutoral advices only to use it on a locale network. I know IDL and RMI only by name - is this what I should be reading about?
If one of you guys have a source-code example on how to make java programs communicate over the net, please post it!
Regards Albert

Assuming this is "wide area" stuff, not just on a local area network, your best bet is to stick to http connections. You need a web server, probably Tomcat.
Your client can connect using URL.openConnection().
As to protocols you could use SOAP. It has the advantage that you can get the code for it for free, but it can be pretty complicated to configure. In particular it only knows how to transmit a limited set of object types and if you want to go beyond them you have to write converters. SOAP servers typically run under an web server anyway. SOAP converts all the data to XML for transmission.
However it may be simpler to use Java's built in serialisation facility and send your data as an ObjectStream.
In the set up you're talking about the message going to the server seems a lot simpler than the response. It may make sense to send your data as normal keyword parameters of a POST transaction but to have the server respond with an Object stream. That's well within the normal operation of a web server.

Problems in SQL Connection from Java program to Oracle 8.1.7

Hi,
I am java program that connects to Oracle 8.1.7 .
Client: java code on Windows 2000

How can java programs execute automatically when it connects to network

How can java programs execute automatically when it connects to network.
Thanks in Advance friends Shackir

Your computer? If that's what you mean, this is not a Java question. It's an OS operational/administrative question. Executing any program, whether written in Java or not, based on some system event has to do with that system, not with the program. If it's possible to do this, you'd do it exactly the same way for a Java program as you would for any other program.
Or is "it" the program itself? If this is what you mean, then it's a nonsensical question. For the program to connect to the network and detect that it has connected to the network, it must already be executing, so asking how to execute it at that point is meaningless.
Finally, I'll point out that "connecting to the network" is a pretty meaningless phrase. Or rather, it has so many potentially valid meanings that it's impossible to know which one you're referring to when you use that phrase. And I'd be willing to bet you don't have a clear picture of that yourself.

Run dial-up connection from Java Program?

Is there a way to run dial-up connection from a Java Program? It needs to platform independent.
Thanks.

I very much doubt it, at least not platform independent. I had a, oops, heck of a time doing that from Visual Basic, where it is much easier to work with operating-system stuff like that than it is in Java. I finally ended up buying a RAS component to call from my VB program.

32 bit compiled Java Program not connecting to 64 bit Oracle 11g

Hi,
I am using one java program to connect to Oracle 11g (64 bit version) using Oracle10g 32 bit client libraries using OCI calls. Below is the program. If I compile it using 64 bit Oracle 10g libraries ($ORACLE_HOME/lib and $ORACLE_HOME/rdbms/lib) , it perfectly connects to Oracle11g but when i compile it using $ORACLE_HOME/lib32 and $ORACLE_HOME/rdbms/lib32, it hangs and keeps trying and takes 100% cpu usage. it does nothing. Please suggest what is going wrong in the environment.

Are you still using Java 1.4? If so, why?
For Oracle 11g you should be using the latest JDBC jar file (ojdbc6.jar) and the latest version of Java 1.6.
You are not only using an old JDBC driver and Java version but are also trying to mix 32 bit and 64 bit operations.
I suggest you start using recommended practices and update your Java and JDBC versions and select EITHER 32 bit or 64 bit operations.
See the Official JDBC FAQ for the details on the support available for various combinations of Oracle DB, Java and the JDBC drivers:

I have mysql server running in one machine and I am accessing from another machine using java program. I have added an user from the server and given all the permission. But its not working. But when I hav java program locally its working.
The following is my program
private Connection getConnection(){
Connection con=null;
try{
Class.forName("com.mysql.jdbc.Driver");
String url="jdbc:mysql://10.5.18.135:3306/test";

Try this way I think you will need the user and password.
Connection con=null;
try{
Class.forName("com.mysql.jdbc.Driver");
// assuming database test
// assuming user is root
// assuming user password is me
String connectionString="jdbc:mysql://10.5.18.135:3306/test?user=root&password=me"
con = DriverManager.getConnection(connectionString);

Unable to connect to Oracle 8i through a java program

Hi all,
I have Oracle 8i standard edition. Does this allow remote clients such as a java program trying to connect through a JDBC program?

Yes, you should be able to connect to the Oracle database as long as you have your listener listening on a particular port, your JDBC URL has all the necessary info and you are using Oracle's JDBC driver.
