Java-Program for JCO-Connection

Hallo experts!
I tried to get a Java-Program running which should establish JCO-Connection to a SAP-System and got the following error message:
java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'
JCO.nativeInit(): Could not initialize dynamic link library librfc. Found version "640.0.144" but required at least version "640.0.161".
at com.sap.mw.jco.JCO.<clinit>(JCO.java:776)
at JCOTEST.main(JCOTEST.java:24)
Exception in thread "main"
Anyone got an idea?
Thanks for your help in advance.

Thank you Jens,
it worked fine with the newest JCo-Download.
Now I seem to have some Network problem: ip not reached:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed
Connect_PM GWHOST=10.251.24.10, GWSERV=sapgw10, ASHOST=10.251.24.10, SYSNR=10
LOCATION CPIC (TCP/IP) on local host
ERROR partner not reached (host 10.251.24.10, service 3310)
I need to talk to our network manager in the firm.

Hi !
Check this to verify that you are correctly using JCO:

how can i apply this java program for a jsp pagewhy do you want to do this ?
Your program reads from a file on the disk and formats based on a patterm.
Jsp is not intended for such stuff.

Where can i find .properties file for jco connection?

For jco connection to SAP, we need .properties file. Is this file already contained in Exchange Profile or somewhere??
If yes, where can i find .properties file for jco connection or what is the path to this file?
OR, do we have to create manually??
Any help is appreciated.
Thanks.
Karma

Hi Karma,
Please take a look at these..
Where to set up the JCO connection?

Change password for JCO connections

Hi,
In our landscape we have around 80-100 applications running and there are 300-400 JCO connections on an average. We have 4 servers like this. Earlier we used to have developers user id and password for JCO connections. Now we have decided to have a universal userid and password for all the JCo connections. My question is there any way by which we can change the passwords for all the JCO connections without going to each one of them individually as it is a hectic task.
Thanks & Regards,
Vijith

Hi Vijith Kumar,
Look at the following blog:
/people/anilkumar.vippagunta2/blog/2007/02/06/dynamic-jco-creation
I guess that if you can create JCO by code you can also edit it...

Running a Java Program for every shut down of system

Hi
I have a java program that sends an email to the Admin of my network.
But this is program i just want to execute for every shutdown and on of my system
Please Tell me how to execute my java program at system shutdown time and on time..
Thanks

Despite your objective, this is not a Java issue. The real question is "How does one run a program just before system shutdown?"
How you execute such an application is system dependent. Java doesn't know when the system shuts down, only when the JVM shuts down. Unless you're willing to have JVM running the entire time the system is up, you'll need native code to detect system shutdown & launch the notification app.

Exception while Running a Java Program for UME.

Hi Experts,
                       I am trying to run a java program to acess UME. Its a sample to create user but all of my samples are throwing this exception in NWDS (Console).Can anyone tell me why is it throwing this exception .
com.sap.security.api.UMRuntimeException: UME factory 'com.sap.security.api.IUserFactory' cannot be accessed because UME initialization has not started yet.
Please check
        UMFactory.isInitialized() before using UME functionality.

Thanks in advance

Hi,
Earlier i faced the same exception when i tried to call the UME form Standalone java application,To resolve this i used stateless session bean approach. i follow the Below Mentioned Steps,
1:-- create an J2EE -- EJB module project.
2:-- Create stateless session bean and define the require methods ,implement Local and remote interface methods in your bean class.
3:-- refer the UME apis in EJB Projects build path.
4:-- Call UME in Bean class methods.Build the EJB project and Archive.
5:--Now create an Enterprise application Project ,Include the EJB module project to your EA Project by right clicking on EA project.Build EA project and EAR file
6:--Deploy the EAR file on your server.
7:--Now from your standalone java application include these two projects in Project tab of your Application.
8:--Lookup the stateless session bean in your java class by its default JNDI name ,Obtain remote or local Home interface,And execute the BEAN Method which deals with UME.
You can also refer this tutorial in some parts of it UME apis(like IUser,UMFactory) are used in Servelets and EJB ,You can download this tutorial source from SDN for your reference.

The JAVA program for "Philosopher Problem"

When I learn the book of "Operating Systems (Design and Implementation)"(written by Andrew S.Tanenbaum), I try to write a program for the "Philosopher Problem" . In the book there is a sample of this problem in C language, and I write it in JAVA. The following is my program, I have tested it. It is correct, but maybe it is not the most efficient way to solve the problem. Can you think out a more efficient program in JAVA to solve this problem?

this problem is about learning how to use threads/synchronise objects etc, the efficiency of the code isn't really an issue, if that's what you mean. As for the efficiency of the solution, it's very hard to tell how efficient it is, but as long as all the philosphers get to eat there's no problem. I haven't really scrutized your code, but I'm not sure that you have a deadlock free solution: as long as it is possible for all the phils to pick up one fork at the same time there's a problem, and it seems from your code that each philosopher will pick up "his" fork. Again, I could be wrong, I haven't really looked. If you haven't come up with a solution, try drawing it on paper and working it out, or if you're lazy a quick google will probably give you the answer, but I'm pretty sure nobody here will :)

Java program for installing font on windows

Hi,
I want to write a java program that installs required fonts on windows machine. On my machine windows is installed on "C:\WINDOWS" directory.
So, naturally "c:\WINDOWS\Fonts" directory I want to paste my font files.
I am writing file handling code for the same. But, how to know dynamically the location of windows installation directory?
I tried using System.getProperty("windir"), but it is not working?
Can somebody help me?
regards,
Anand

1) Use VB
2) Who said that such a property exists?
3) In Java 1.5, use System.getEnv()

Authentication method for JCo connection in XSS installation

Hi All,
I have a query which perplexes me. I am implementing XSS (ESS/MSS) on SAP Portal EP6 SR1 with an ECC5 backend for prototype purposes.
When I follow SAP's help steps to setup JCo connections, it states that for the metadata connection you should use a security authentication method of 'User/Password', but for the application data connection you should use a security authentication method of 'Ticket'.
Does anyone know why the difference in methods here? Is it possible to use 'User/Password' for both? Any thoughts would be appreciated.

Hi john,
User -ID /Pwd method can be used to access the backend for both types of Data as per your scenario.
User -ID /Pwd method and logon tickets both can be used to access data in backend.
The difference lies in the scenario with which you are accessing the back-end.
If all your portal users are same as backend users then you can select Logon ticket methods.
If they are going to be different then you need User-ID /Pwd method .
Check the following link to get a clear picture:

Hope it helps.

Port for JCO connection

Hi,
I am accessing an R3 table using JCO connection. Can someone please let me know the port no. of the server which will be neccessary for doing this?
Thanks

Hi Jacob,
try {
con = cgservice.getConnection("ISOILESconnect", cp);
ix = con.createInteractionEx();
ixspec = ix.getInteractionSpec();
ixspec.setPropertyValue("Name", "Z_MESSAGES");
rf = ix.getRecordFactory();
// CCI api only has one datatype: Record
RecordFactory recordFactory = ix.getRecordFactory();
MappedRecord importParams=recordFactory.createMappedRecord("CONTAINER_OF_IMPORT_PARAMS");
MappedRecord exportParams = (MappedRecord) ix.execute(ixspec, importParams);
output = (IRecordSet) exportParams.get("LI_MESSAGES");
This is the piece of code im using, I have already created a system on both the servers and tested them successfuly. But for some reason it works on one but does not give an output when i run it on the other server.
I get an error which tells me that no output is returned.
Thanks.

MII 12.1 time out for JCo Connection

I'm running this MII transaction that, is using a JCO connection to run a Function Module in SAP.
The problem we have is, that function module takes more than 60 seconds to run an return the values, that is correct because we are gathering a big amount of data, so if we run the function Module inside SAP it works ok, BUT, if we run the transaction from MII we receive a time out after exactly 60
seconds.
We have already modified several time out parameters inside MII
but those changes are not making any difference.
Do you know where that JCo time out parameter is inside MII 12.1?

Hi Salvador,
Try to increase the session timeout to 300 in SAP Menu --> System Properties. Initial it will be 60 sec only.
And increase MII workbench Read Timeout as well. Help --> Setting --> Read Timeout
If it doesn't solved your problem, go through below post
How to set timeout for each level in MII?

JSP Unable to Load Class (posted in Java Programming for 5 Dukes)

I hope this isn't a violation of forum etiquette, but I posted my question in Java Programming at http://forum.java.sun.com/thread.jsp?forum=31&thread=203255
I realize now that it may have been wiser to post it here, but I have some replies already and it makes more sense just to inlcude the link.
Can anyone assist with the question at http://forum.java.sun.com/thread.jsp?forum=31&thread=203255
It's worth 5 dukes.

Try changing <tagclass>E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes\tags.ExampleTag</tagclass> to <tagclass>tags.ExampleTag</tagclass>
because <tagclass> tag is for the class name and not the location of class file
And make sure your ExampleTag.class file is in
\WEB-INF\classes\tag\ExampleTag.class

User Id creation for Jco connections

Hi,
Need to create a user for verifying the Jco connections. Please help me with the steps of creation and how can it restricted only for verifying the connections.
Thanks

Hi Daneil,
Best way is to do it yourself.
1 - Create a user having full access (SAP_ALL and SAP_NEW and RFC Full access as well).
2 - Set up the JCO connection with this user ID.
3 - Put a trace (ST01) on this user ID and then test the connection.
4 - Analyze the trace file and create a role having all the access pulled in the trace.
5 - remove all the access from the above user and assign the role created in 4.
6 - Put a trace once again on this user Id, just to ensure that if there is a miss in any authorization(failure) then you will be able to capture that as well. Update the role accordingly.
Hope this helps.
