JCO calling error

Hi, experts:
I got a problem when calling a RFC from EJB by using JCO object.
Sometimes JCO return last calling result, and when i manual calling again. JCO return correct value.
How to reset connection?
Thanks for any hints.
Best regards,
Nick.

<div style="text-align:left">But another situation happen that is sometimes JCO return empty result.
Could it be previous release action to made next time calling fail?</div>
Hard to comment without knowing details. Assuming that all your calls are made in a new context, the connection should be kind of stateless. However, in theory you could of course have an RFC function that behaves different over time or where it runs (application server), etc.; in practice though this is unlikely.
To better understand what's going on I'd recommend to activate tracing. You can set the trace level by passing the command line argument -Djco.trace_level=N (where N is between 0 and 10, 10 being most detailed trace) and -Djco.trace_path=<path> to your java executable (or however you want to accomplish that on your J2EE server).
In addition it might help to also activate tracing for the executed RFC calls by setting the environment variable RFC_TRACE=1 and if more details are required RFC_TRACE_DUMP=1.
Maybe there's some silly problem and the request parameters are different or not as expected...

Error in BPM: "COMMUNICATION FAILURE" during JCo call. Error opening an RFC

hello experts
i am receiving the above error incase of BPM scenario where i am having a Transform step and synchronous RFC step.
i referred to the few threads discussing such problems and was trying to find whether my mapping is correct and i tested my mappings using my payload which looks good.
When looked into the Mapping trace of the BPM "Show container" i found error ""COMMUNICATION FAILURE" during JCo call. Error opening an RFC connection" and it seems that when BPM is attempting to call interface mapping it is throwing this error.
Thanks in advance.

hi,
I think no problen with the mapping part,

JCO.Server Error while trying to execute a RFC program from SAP

Hi,
We are connecting to an external registered server program from SAP via Web Methods.
The external server program is registered with the SAP Gateway. We have created a TCP/IP RFC destination and are able to connect to the destination successfully via SM59.
An RFC function is created in SAP and is called using the syntax CALL FUNCTION "/NGN/BAPI_STRE_SEARCH_PROCESS" DESTINATION 'PRDB2B'. We have also handled the COMM_FALIURE and SYSTEM_FALIURE exceptions in the function call.
We are monitoring the gateway via SMGW and see a connection log to the RFC destination as below
Number - 10
LUname - dev01
TPName - sapgw00
User - KRAORANE
Status - CONNECTED
Symbolic - PRDB2B
Conversation - 86520353
Prot - REG
SAP return code - 0
CPIC rtn code - 0
The external program returns results as expected.
However sometimes the RFC fails and returns the message JCO.Server could not create server function /NGN/BAPI_STRE_SEARCH_PROCESS.
We are not able to figure what exactly is causing this error. Any help will be highly appreciated.

How to handle JCO.AbapException on JCO call in ABAP

Hello Forum,
I am implementing an JCO Server scenario.
I use dynamic repositories like Example7.java from the JCO documentation.
Example7 throws an JCO.AbapException if anything went wrong, e.g. the function is not implemented. My coding is like:
     protected void handleRequest(JCO.Function function) throws AbapException {
          try {
            // Process incoming requests
          } catch (Exception e) {
            log.error(this.getProgID() + ": error handling request " + function.getName(), e);
            throw new AbapException(function.getName(), e.getMessage());
How to react on this AbapException?
The examples in SAP Help documentation only catch
SYSTEM_FAILURE and COMMUNICATION_FAILURE.
I implemented the JCO call as well like following.
CALL FUNCTION 'MY_JCO_FUNCTION_MODULE'
    DESTINATION JCO_DEST
    <...>
    EXCEPTIONS
      SYSTEM_FAILURE        = 1 MESSAGE RFC_MESS
      COMMUNICATION_FAILURE = 2 MESSAGE RFC_MESS.
But these two are only thrown and caught when something with communication went completely wrong, e.g. RFC not found.
When the exception in the JCO server occured and JCO.AbapException was thrown I always get an ABAP short dump, i.e. the exception was not handled.
Additionaly, the exception is named like the JCO function called and the message text which was submitted to JCO.AbapException is not displayed. I think that means that the AbapException was not recognized at all?
The JCO API doc says:
Creates an exception with the specified key. This constructor is normally used in the server's handleRequest() methods to throw an exception which is part of the function interface definition. In such a case the SAP system will not raise a system exception. If however the specified key is not a defined exception for the currently processed function module the SAP will raise a system exception.
But whether I define an exception in the function interface definition named like the module (thererfor new AbapException(function.getName(), <...>)) or not, it always dumps. I understand the exception that a system exception is raised when the exception is not defined? But this is not been handled with above ABAP code as well.
What is wrong here? Could anyone post an example please how the exception has to be handled?
Please note that I do not define static repositories but have the remote function defined on in the ABAP server to be used by dynamic repository (like the STFC_CONNECTION test rfc). Am I right that the exception should be defined in that RFC remote definition?
Thanks,
Carsten

Dear everybody,
Finally I solved this old problem
I am a novice in JCO and played a little with the problem and found an old reference to the difference between J2EEAbapException and AbapException classes. I modified my program and it works! ABAP caller gets the correct exception, not system_failure! The details:
1. modify beanname.java source
     import com.sap.mw.jco.JCO;
     import com.sap.mw.jco.JCO.J2EEAbapException;
     public interface ... extends EJBObject {
    public void processFunction(JCO.Function function) throws RemoteException, J2EEAbapException;
2. modify beannamebean.java source
    import com.sap.mw.jco.JCO.J2EEAbapException;
     public void processFunction(JCO.Function function) throws J2EEAbapException {
     throw new JCO.J2EEAbapException("NODATA");
3. modify beannamelocal.java source
      import com.sap.mw.jco.JCO;
     import com.sap.mw.jco.JCO.J2EEAbapException;
          public void processFunction(JCO.Function function) throws J2EEAbapException;
I hope it helps for somebody else too!

"SYSTEM FAILURE" during JCo call.java.lang.reflect.UndeclaredThrowableExcep

Hi All
I have developed Java mapping program where I am calling three BAPI in sequence and trying to map all three bapi data to single Target XML file or Multiple target xml files depends on the in coming data.
Now I want these files name should be genereted dynamically .So I have used below Dynamic Configuration code in my java mapping program.********************************************************************************************************************************************************************
try
     String currDate = new String();
     String currTime= new String();
     DateFormat dFormat=new SimpleDateFormat("yyyyMMdd");
     DateFormat tFormat = new SimpleDateFormat("HHmmss");
     java.util.Date date = new Date();
     TimeZone cetTimeZone = TimeZone.getTimeZone("CET");
     tFormat.setTimeZone(cetTimeZone);
     currDate = dFormat.format(date);
     currTime= tFormat.format(date);
     String pubDate=currDate + currTime;
     String ext=".xml";
     String event="-1_1-";
     trace.addInfo("******** Before Dynamic Configuration ***************" );
     DynamicConfiguration conf =(DynamicConfiguration)container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
                                        DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File","FileName" );
     trace.addInfo("******** After Dynamic Configuration ***************" );
     String tempFileName="NL09-"eventponum+ "-" pubDateext;
     trace.addInfo("The name of the file is : " + tempFileName);
     conf.put(key, "tempFileName");
            catch (Exception e)
                 trace.addWarning("Error While creating File Name"+e.getMessage());
                 throw new Exception("Error While creating File Name",e);
Now the problem is when I am using above code I am getting following error
"SYSTEM FAILURE" during JCo call.

<SAP:Retry>A</SAP:Retry>
</SAP:Error>
Could please tell me why I am facing this problem only when I am using Dynamic configuration code.
If I dont use Dynamic configuration code then I am not getting any error .But my requirement is to generate dynamic file name (Note I have tried with Variable Substution also, It is also not solving my problem as I need time stamp of ("CET") time zone).

Hi Abhishek,
Yes I have appended throws StreamTransformationException and imported the relevant StreamTransformationException class also.
Here I am getting strange thing when I am adding dynamic configuration code " SYSTEM FAILURE" during JCo call. But Jco cal is something to internal systems which does not relate to Dynamic Configuration.
If I run my code with out any Dynamic Configuration code then it is running with out any errors.
But I need this Dynamic Configuration inorder to generate dyanamic file name.

JCO call from ABAP to Java

Hi to all,
I'm trying to perform a JCO call from an abap function module to a java server program. I've built a java application that extends JCO.Server library, but I'm not able to register my Program to SAP R/3 in order to be called from the abap Function module. when I run my java application directly on XI Server, I receive this error:
"Could not load middleware layer com.???.MiddlewareJRfc".
Can anyone help me, please?
Thanks!

Cannot turn on iphone cellular calls error

When trying to activate iPhone Cellular Calls, I get the error "cannot turn on iphone cellular calls error, FaceTime and iCloud must be signed in to the same Apple ID to use iPhone cellular calls" I am signed onto the same accounts in both places and cannot figure out what is wrong. Any help would be appreciated! Thank you

If you're trying to make calls from a mac, then you should make sure to enable FaceTime calls from your AppleID (email address) on both the mac and the iPhone. Don't uncheck your phone number, either. FaceTIme should be enabled on both devices with both your phone number and your AppleID.
For some reason, this is what had to be done for me to be able to make phone calls from my mac without receiving this message on my iPhone. I know it isn't ideal because we shouldn't have to enable FaceTime calls via AppleID, especially if we won't be using it with our AppleID, but this is what worked for me. Once you enable FaceTime calling from your AppleID on both the iPhone and your mac (while also keeping the calling enabled via your phone number), then try to turn on iPhone cellular calling on your iPhone. It should work, and then you can try to make a cellular call on your mac.
Some people may think that this isn't a fix because they might think I am talking about FaceTime audio calls. But I'm not. Try this and report back if you can.

Smartform Printing : Error in spool C call: Error from TemSe

Hi! everybody,
I am stating my problem as follows : I have to print a bar-code sticker of size 10 X 7 cms. I have worked on bar-codes before this also. This time the output from a smartform is to be given to a ZEBRA TLP 2844 printer. I initially encountered problems in printing. The data does not fit on to the page.
After a lot of searching I found that ZEBRA was a partner of SAP and that a special device type needs to be created for output from a ZEBRA printer. I did this two times. Each time my steps were as described under.
To create the device type I did the following :
1. I finally found the driver from the ZEBRA website from http://www.zebra.com/id/products/global/en/utilities/sap_device_types.UtilityFile.File.tmp/Zebra_SAP_Device_Types.zip From this I uploaded the driver for 203 DPI zebra printer with IBM code 850 font file name "YZB200.PRI" into the transaction SA38.
2. Then I created a new device ZEB10 in SPAD after assigning my format to the device.
Thereafter, I tried to print my sticker. During this procedure, on selection of the new device type, the fonts automatically changed to ARIAL in the print preview. When I give the print command (Spool request : Print immed = X, Delete after output = X & New spool request = X) it gives an error message Error in spool C call: Error from TemSe.
Since the output had not been issued, I opened the spool request to view its TemSe characteristics. Here I found

I hope this data helps you help me. Please ask for more data if you wish. Also, I have searched vastly for this error on the net have already come across the link http://help.sap.com/saphelp_45b/helpdata/en/d9/4a8f9c51ea11d189570000e829fbbd/frameset.htm but to no use. On the SDN, I have not found a similar thread and that is why I decided to post this problem here, hoping to find a solution. Kindly help.

The transaction has been terminated. This may be caused by a
termination message from the application (MESSAGE Axxx) or by an
error detected by the SAP System due to which it makes no sense to
proceed with the transaction. The actual reason for the termination
is indicated by the T100 message and the parameters.
Additional documentation for message E0 022
