Mainframe connection through java

Hi,
Is it possible to connect to a mainframe and retrieve the results from it i.e., the data stored are in the form of cards(record types).Is it possible to connect to such set up using JDBC connectivity as we do for the normal RDBMS connection..
Kindly help me in this regards
Wiht thanks in advance
subra

Why on earth should a "mainframe" (you even didn't tell us which OS) be such a magic zone that even Java can't enter it?
How do other programming languages manage to connnect to a DBMS on a mainframe?
How has for example Oracle succeeded to be used on mainframes?
I think you should ask your DBMS' vendor at first.
"Mainframe" is a collective name for certain hardware structures only.

Problem with socket connection through Java Embedding...

We are trying to create a simple socket connection to a socket server through BPEL PM using the Java Embedding component.
BPEL Process : Client makes an asynchronous request. Passes an input variable. The input variable is sent to the Server Program through a socket connection through the Java embedding component.
Server: We are running a simple Socket Server program from command prompt.
The code below works fine as long as we do not try to receive a response from the server (Commented Code).
If we uncomment the code and try to receive a response, it refuses to create an instance for the BPEL Process. And sometimes restarts the BPEL Server.
Client Code:
String msg="NONE";
try{
org.w3c.dom.Element input = (org.w3c.dom.Element) getVariableData("inputVariable","payload","/client:clientProcessRequest/client:input");
msg = input.getNodeValue();
Socket clientsoc=new Socket("ServerIP",1000);
PrintWriter out1=new PrintWriter(clientsoc.getOutputStream());
out1.write(msg);
out1.flush();
BufferedReader cin1=new BufferedReader(new InputStreamReader(clientsoc.getInputStream()));
msg=cin1.readLine();
setVariableData("outputVariable","payload","/client:result",new String(msg));
clientsoc.close();
catch(UnknownHostException e)
System.err.println("Don't know about host: dev.");
System.exit(1);
catch (IOException e)
System.err.println("Couldn't get I/O for "+ "the connection to: dev.");
System.exit(1);

Well The issue was somewhere else due to it reading too much of data. It ran but my program is very slow (approx 2-3 hrs).
I am worried about the speed...
is it because of the large amount of data.. 23,355,459 records..?? or there could be some issue in programming probably memory leak etc..??
-> reads db
-> for each record set
-> perform different operation/ writes to file

RFC connectivity through JAVA

Hello sir,
I have create 1 java class file which connects to SAP DB through RFC connection.
I have put sapjco3.dll,librfc32.dll,sapjcorfc.dll in to the folder windows\system32.
Its working fine on windowsXP, but not working on Windows Vista and windows server 2003.
its giving error as
java.lang.UnsatisfiedLinkError: D:\splerp3\sapjco3.dll: The application has failed to start because
its side-by-side configuration is incorrect.
please tell me what configuration i have to do for vista and server 2003.

Hi guys,
please pay attention to the given infos on the JCo download site. It says:
Note: Starting with JCo 2.1.4 and JCo 2.0.11, JCo requires the Visual Studio .NET C/C++ runtime libraries on Windows platforms.
Starting with JCo 3.0.0, it requires the Visual Studio 2005 C/C++ runtime libraries. See SAP note [684106|https://service.sap.com/sap/support/notes/684106] for details on how to install them.
Installing the VC redistributable packages from Microsoft will solve this issue.

Getting result from a telnet command through Java

Hi,
I've been using a set of classes found here: http://javatelnet.org/
to do telnet through Java in a non-interactive mode.
However I've got a problem when retrieving the result of a command sent to the remote host: the classes read the stream until the prompt is encountered; my problem is I must execute commands on several remote hosts, and the prompt is not necessarily the same on all hosts.
Is there a simple means to establish a telnet connection through Java and retrieve the result of the commands?
Any help would be appreciated.

Thanks again, this is a very good article
I see it is still the same strategy to get the result of a command : wait 'til the prompt is sent. Maybe there is just no other way to get it .
But as I don't know the prompt on the different hosts I have to query, this won't do it.
The article gave me an idea though : I only need to count the files in a directory on the remote host; until now I was trying to send the 'ls | wc -l' command by Telnet.
Maybe I can simply do it by FTP (retrieve the list of files, and then count the lines with JAVA).

Can I connect to Oracle server7.1 through Java-JDBC using the latest thin drivers???

Hey Gurus,
Please help me .
MY Current requirement is to connect to multiple oracle 7.1( and other variants) servers running on different operating systems, through Java/JDBC.
My FIrst question is, can i connect to older versions of database using latest drivers?
I could connect to the server running on SCO-oracle 7.1 using SQLNet8.1.7 under windows. But the same is not happening when the client is on Linux.But I need to connect from linux
It says ORA-03113 - End of communication channel.
What may be th problem.
If any one could show some pointers where I can get more information about this problem would be helpfull
THanks
Lokesh

I tried the classpath suggestion above (not the one modifying the .xml file) , but it didnt work for me , I am using WLI 10.3.1 and trying to connect DB on 8.1.7 V . I downloaded the classes12.jar and the ojdbc14.jar file from the oracle and placed in lib and the even included the classpath , but i again got the same exception .
All this while i was selecting the option Oracle Driver Thin from the DataBase Driver when creating the connection pool from console . I tried with "BEA Oracle Driver (Type 4)" and it worked for me .. Although the option "BEA Oracle Driver (Type 4)" lists only the DBs from 9.0.1 to 11 G , but in my case using this driver i am able to connect to Oracle DB 8.1.7 . So all you guys if it classpath doesnt fix the issue try out by selecting Driver , "BEA Oracle Driver (Type 4)" .
Manoj , this will fix the Connection pool part of the ques, but for the java part Try to load the Driver class "weblogic.jdbc.oracle.OracleDriver" before connecting to DB with Class.forName.
Thx

Connecting to R/3 System through Java Web Dynpro forms.

Hi,
I have a requirement in which I have to send data to R/3
from Java Web Dynpro screens.
I will design the Java Web Dynpro screens and write a RFC Model.
I will write a RFC in se37 which will connect to the RFC Model.
Before creating the RFC in se37, I will create ztables in se11.
I will write a ABAP Report to see that all data enters the ztables.
I need some guidance with regard to this.
Do, the RFC Model have the access of the ECC(R/3) System.
What are tasks to be told the Basis guy so, that RFC being called from through Java Web Dynpro?
Please provide me some documents with regards to this scenario.
Regards
Neha Singh

Hi Neha,
The steps you provided is clear enough to connect to a R/3 system through the WD forms.
On creating the model you need to give two inputs such as
logical system name for model instance
logical system name for RFC metadata
there will be 2 default values, also you can create your own JCOs in the <servername>:<port>/devinf of the server or u can ask your basis team also.
Before creating the JCO , the SLD (System Landscape Directory) needs to be configures, that your basis team will know.
other than that once you create the functional module in se37 make it RFC enabled , and once you import the RFC model , you can give your ECC system user name and password and search for RFC you have created from the list of RFC.

Sam Charles J.

Hi ,
   I found a document which says that MDM4J is the legacy API and is considered deprecated .The MDM Java API is the new one .I have both of them in the java build path . I am not sure if this is that cause of the problem .
Now I had a look at the javadoc for the new API but I am not able to locate the class to obtain a connection to the MDM server from a custom application being built in Netweaver Developer Studio . Can someone help me out with the same ?What would be the code to obtain the connection to the MDM server with the new JAVA API ?

Getting problem when connecting to SMTP server through java code

Hi all,
I am getting problem when i am going to connect with "Kerio SMTP server" through java code. The error what i am getting is :
"[16/Sep/2008 15:59:09] Sent: Queue-ID: 48cf8a73-000000f9, Recipient: <[email protected]>, Result: failed, Status: 5.3.2 554 5.0.0 Too many hops (101, max 100), message looping" when sending an email from [email protected]

Looks like something is set up wrong on your server that's causing messages
to be forwarded around a loop too many times without ever reaching the destination.
For instance, if server A forwards to server B, and server B forwards to server A,
this would happen.

Problem in Connecting to SQL DB through Java

Could this error be my fault or would it be the servers fault that i cannot connect to it?

        at altomarelab9.BookConsoleApp.main(BookConsoleApp.java:20)
Java Result: 1if there is not enough information i can supply more of my code thanks

So to debug it you start with the following
   babyhuey.cis.temple.edu:3306 First might as well validate the domain. On windows you do this
   nslookup babyhuey.cis.temple.eduFor me I get the following result which indicates the domain exists.
   Name:    babyhuey.cis.temple.edu
    Address: 155.247.182.88So now you check the port by telneting to it
   telnet    babyhuey.cis.temple.edu 3306 And this fails due to connection failure.
That proves conclusively that there is no open port for that domain and that port.
So that means one of the following is true.
1. The domain you are using is wrong. Solution: Ask the professor.
2. The port you are using is wrong. Solution: Ask the professor.
3. The school does not have the network configured correctly. Solution: Your professor must solve this via the network admin at the school.
4. The school does not allow you to access this from outside the school. Solution: Your professor needs to explain to you that that you must do it only at the school (or perhaps he did and you missed that part.)
Further googling I found that 3306 would seem to be a likely port for MySQL. That would tend to suggest that 2 is not the explaination.
