JCo - asynchronous calling RFC

As far as I know, there is possibility make asynchronous RFC call via JCo.
How can I get return values from such calling?
Is there some code example, please?
Thanks.

Exception when using jco to call rfc

Hi All,
    When I used JCO to call rfc 'RFC_GET_TABLE_ENTRIES' to get the records of the table 'MARC'. I met the following Exception, it seems that there are too many records in the table. And I have used the import parameter 'MAX_ENTRIES' to set the number of records , but it seems no use. So is there any suggestion to solve this problem?
Exception in thread "main" com.sap.conn.jco.JCoException: (104) RFC_ERROR_SYSTEM_FAILURE: No storage space available for extending an internal table.

          client.connect();
          IRepository repository = JCO.createRepository("REP", client);
          JCO.Function func = RFC_READ_TABLE.createFunction(repository);
          func.getImportParameterList().setValue("MARC", "QUERY_TABLE");
          func.getImportParameterList().setValue(";",    "DELIMITER");

          func.getTableParameterList().getTable("FIELDS").setValue("MATNR", "FIELDNAME");
          client.execute(func);
          JCO.Table table = func.getTableParameterList().getTable("DATA");
          System.out.println("NumRows: " + table.getNumRows());
          System.out.println("Content: " + table.getValue("WA"));
Result:

JCo Call RFC

I have defined a RFC and call it via JCo.
The RFC is used to fill data to my table.
The problem is the data can be fill via the import parameter, but the table parameter is not work. I have tested the RFC in function builder and it work.
Here is my RFC:
FUNCTION Z_FYP_BAPI_ORDER_CREATEFROMDAT.
""Local interface:
*" IMPORTING
*" VALUE(PLACEORDER_IMPORT) TYPE ZFYP_ORDER
*" EXPORTING
*" VALUE(RETURN) TYPE BAPIRETURN

DATA: RC LIKE INRI-RETURNCODE,
 NUMBER(10) TYPE C,
 ITEMID TYPE I.
TABLES: ZFYP_ORDER.
TABLES: ZFYP_ORDERITEM.
DATA WA_ORDERITEM LIKE LINE OF ORDERITEM_IMPORT.
CALL FUNCTION 'NUMBER_GET_NEXT'
 EXPORTING
 OBJECT = 'ZFYP_OR'
 NR_RANGE_NR = '1'
 IMPORTING
 RETURNCODE = RC
 NUMBER = NUMBER.
PLACEORDER_IMPORT-ORDERID = NUMBER.

JCO.Function function_read_cont = m_read_container.getFunction();
JCO.ParameterList tables =
function_read_cont.getTableParameterList();
//For Tables
JCO.Table table = tables.getTable("<Your table Name from table parameter>");
// specified number of empty rows at the end of the table

Error while calling RFC

Hi all WebDynpro Gurus
I am using EP7.
I am developing an WD application for KM functionality in which I need to call RFC from backend. I followed the "Creating WD application accessing ABAP function" example.
But when I executed the application I got following exception.
Root Cause
The initial exception that caused the request to fail, was:
com.sap.lcr.api.cimclient.CIMClientException: java.net.MalformedURLException: URL must have a host part
Correction Hints
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
I checked JcO connections in the webdynpro content admin. There the status is unknown and create tabs are disabled.
I checked the SLD connections in content admin , the entries are as below:
Host name : blank
Port: -1
User: blank
Url: http://.-1/sld
Where could i configure these SLD settings and what should be the new entries ?
I dont have permission to view WebDynpro console.
Please help me out.

Vinod,
Claim: "Hello, World" application with WD and RFC is the "Hello, World" application with most complex configuration.
Prove:
1. You need to run http://host:port/sld and import CIM context
2. You need to add technical WebAS ABAP systems to SLD (same URL)
3. You need to run Visual Administrator and setup SLD connection parameters (host, port, user, password)
4. You need to (re)deploy your WD application
5. You need to run web-based WebDynpro Content Administrator and configure JCO connections.
Fortunately, [1]-[4] is necessary only ones per server, [5] is necessary per every application.

How to call RFC in Async Mode using TCP/IP RFC Destination ?

Hi experts,
Can anybody tell me how to call an Async RFC using TCP/IP RFC Destination ?

Can we call RFC in any other way except using adaptive

Hi,
I want to know if there is any possible way to call RFC other than using the adaptive model.
Answers will rewarded.

Hi,
you can use JCO or Enterprise Connector to connect with R/3.

Call RFC from java (j2ee) / call to j2ee from R/3

hello
i´ve browsed the forum for some time to find how to:
1.) call ejb from r/3 system via rfc
2.) call rfc enabled function modules on r/3 from within an j2ee enviroment
but i didn´t quite get it, because i was a bit confused about all the mentionend techniques
what i found out about
1.) use ejb (session bean) and jndi; configure RFC-Engine Service (we use sap webas)
2.) use jco / jca
(or all rfc enables rfm´s are available as web service, but didn´t find anything about this)
so my question:
are these the preferred techniques to connect j2ee (webAS) <-> r/3; if not are there any others, maybe easier methods?
and last but not least: are there any good online tutorials for this topic?
thanks in advance
franz

Just as a short partial reply.
The generic Java --> RFC method is JCO (it will work on older versions as well), you can think of it as a JDBC driver where R/3 is the database, it behaves very similar in many ways.
EJB development on SAP WAS is really not any different from EJB development on any other J2EE server. The deploy tool is superb. very easy to use and the JNDI registry, etc. are standard stuff...
ABAP to EJB calls, haven't looked at this in over a year now, but back then we did a Proof Of Concept based on information at http://help.sap.com and it did work indeed. The only thing was back then that you needed to do a few tweaks to get it to work properly.
As mentioned above, look at the JCO examples and then you can ask more specific questions once you get stuck.
Good Luck!
Cheers,
Kalle

Can not call RFC contains "call transaction" in webdynpro

We use Webdynpro to develope a UI that can create service orders in CRM
system. We create an RFC funciton "ZKLEE_CRM_ORDER_MODIFY" in CRM,which
contain a statement of "CALL TRANSACTION 'CRMD_BUS2000120' USING T_BDC
MODE 'N' MESSAGES INTO MESSTAB.".
But as we exacute the RFC from WEB,we got 3 error messages in the
output "MESSTAB":
1.MESSAGE ID = "DC",MESSAGE NUMBER = "006", MESSAGE = "Control
Framework: Fatal error - GUI cannot be reached".
2.MESSAGE ID = "SY",MESSAGE NUMBER = "002", MESSAGE = "Exception
condition CNTL_ERROR raised."
3.MESSAGE ID = "00",MESSAGE NUMBER = "359",and it is a terminate
message.
The problem is that we can use webdynpro to call RFCs that do not
contain "call transaction" freely. At first we suspect that it is our
RFC function's fault, but we tried it in ABAP enviroment,and it works
OK. We also tried to call this RFC in JSP through JCO,the same error
occurs.
Our system enviroment is CRM 4.0, J2EE 640, kernel 640 patch 109.

HI,
Thank you for your information.
Maybe you are right that BAPI/RFC can not contain "call transaction" statement. But two weeks ago, one of my colleagues tried to use "call transaction" in RFC through JCO in our R/3 enviroment(not in CRM),and he successed.
So I suspect the kernel release. The kernel of R/3 is 640,while CRM is 620(I said our CRM kernel release is 640 before,and it is a mistake.).I will confirm whether what my colleague said is right by myself, and will also told you the result.

Synchronous - asynchronous interface (RFC - XI - jdbc)

hello to everybody!
i want configure a synchronous - asynchronous interface (RFC - PI - jdbc) whit my PI 7.1
This RFC send 2 output tables to PI/XI and i want write it into 2 different tables in a SQL Server Database.
How can i do it?
i tried whit one mapping to a unique outbound datatype...but only header table was insert and not rows.
i tried whit 2 Receiver Interfaces but i have on mapping the follow error:
Multiple inbound interfaces not supported for synchronous calls
so??
other possibility?
BPM?
please help me
Thanks
Alessandro

Hi,
I have a similar problem; I have JMS - PI - RFC synchronous scenario. I will receive message from JMS, and depending on the data received, I should call either of two RFCs (NOT BOTH). The BAPI return message should then be sent back to JMS.
Hence, I have one "Sender/Outbound" Message Interface, one receiver determination for that Message Interface - in which there is "one" receiver (backend SAP system).
In "Interface Determination", I specifed the two BAPIs as two Interfaces, and defined conditions based on "context objects" - since I need to know the Interface Mapping "dynamically"
However, I get the error - "Multiple inbound interfaces not supported for synchronous calls ". any suggestions on how to proceed?
I am posting this question here as it is a related issue. Hope it is fine.
Thanks,
Archana

Calling RFC Adapter fails - convert error

Hi,
I have a problem with calling RFC Adapter. I'm using JDBC->XI->RFC scenario. JDBC does just "select 'W' from dual". In the destination SAP system RFC function is created for test purposes. This function has one parameter - string type. After calling it, it should write a sysdate into the SAP Z_ table. The XI should call the function with the 'W' parameter. But this fails. Everything is ok, but calling the RFC returns following error (copied from the Runtime Workbench -> Message Monitoring :
Exception caught by adapter framework: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not convert request from XML to RFC:com.sap.mw.jco.JCO$Exception: (130) JCO_ERROR_XML_PARSER: Expecting a tag to begin with '<' instead of 'W', in "u
(Yes, this is thw whole error message. I don't know what u should be...)
Did someone get this error?
Thanx 4 answers, Peter

Hello all,
Let me reopen the topic of my colleague. I'm facing the same error though with bit different symptoms. Here it is.
ERROR msg:
Exception caught by adapter framework: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not convert request from XML to RFC:com.sap.mw.jco.JCO$Exception: (130) JCO_ERROR_XML_PARSER: Expecting a tag to begin with '<' instead of 'Z', in "T
The XML message (MainDocument):
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:Z_BAPI_ACCESSIBILITY_TEST_XI xmlns:ns0="urn:sap-com:document:sap:rfc:functions">
<BAPI1008 />
<PARAM>Z_XID_500_ACC</PARAM>
<ZTTOTH_BAPI1008 />
- <ZTTOTH_STRUCT>
<PARAM1>Z_XID_500_ACC</PARAM1>
</ZTTOTH_STRUCT>
</ns0:Z_BAPI_ACCESSIBILITY_TEST_XI>
According to the error message the parser expects behind string ...<ZTTOTH_STRUCT><PARAM1> another tag, but the question is why.
To make all this more funny here I paste another XML message of BAPI calling which works fine (without the error described above):
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:Z_BAPI_PARAMETERS_TEST_XI xmlns:ns0="urn:sap-com:document:sap:rfc:functions">
<PARAM>Z_XID_500</PARAM>
- <ZTTOTH_STRUCT>
<PARAM1>Z_XID_500</PARAM1>
</ZTTOTH_STRUCT>
</ns0:Z_BAPI_PARAMETERS_TEST_XI>
The BAPI functions are absolutely the same except those other two import-pramater structures (BAPI1008 and ZTTOTH_BAPI1008). I'm gonna to try to add those import-parameter structures into Z_BAPI_PARAMETERS_TEST_XI, but anyway - this is weird.
Does anybody have an idea, what should be wrong ?
Thx. Tom

Calling RFC from custom connector

Hi,
I am developing a custom connector for UWL to get tasks from 3rd party system.
I need to call a RFC from backend SAP system to complete Input data for this 3rd party provider.
I assume that I have to make an RFC call from getItems() method of connector.
Any idea how to call a RFC from UWL custom connector code?
Please help.
Thanks & Regards,
Amey

Hello Karri,
Yes, I am aware of two ways of calling RFCs from Java code.
Normally, I use following approach to call RFCs from my other Portal Components (JSPDynpages): -
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
IPortalComponentContext myContext = request.getComponentContext();
IPortalComponentProfile myProfile = myContext.getProfile();
String sapSystem = myProfile.getProperty("SystemIdentifier");
ISystemLandscapeWrapper landscapeWrapper = (ISystemLandscapeWrapper) UMFactory.getSystemLandscapeWrappers().get(0);
ISystemLandscapeObject systemLandscapeObject = landscapeWrapper.getSystemByAlias(sapSystem);
IJCOClientService clientService = (IJCOClientService) PortalRuntime.
getRuntimeResources().getService(JCO_CLIENT);
request.getNode().putValue(LOCALE_NODE_KEY, Locale.ENGLISH);
IJCOClientPoolEntry poolEntry = clientService.getJCOClientPoolEntry(sapSystem,request);
JCO.Client client = poolEntry.getJCOClient();
client.connect();
IRepository repository = JCO.createRepository("repository", client);
IFunctionTemplate functionTemplate = repository.getFunctionTemplate(Z_BAPI_EMP_GBU_GET);
JCO.Function function = new JCO.Function(functionTemplate);
JCO.ParameterList importList = function.getImportParameterList();
importList.setValue("US", "OBJTYP");
importList.setValue(request.getUser().getUniqueName(), "USRID");
client.execute(function);
JCO.ParameterList outputList = function.getExportParameterList();
gbuCountryBean.setGbu(outputList.getString("GBU"));
gbuCountryBean.setCountry(outputList.getString("COUNTRYCODE"));
gbuCountryBean.setPersArea(outputList.getString("PERS_AREA"));
gbuCountryBean.setCompanyCode(outputList.getString("COMPANYCODE"));
When I tried implementing same in UWL custom connector, I am not able to get instance of 'request' object.
Any hints/ideas on this?
Hence as an temporary alternative, I wrote following to successfully execute RFC.
mConnection = JCO.createClient(sapclient, sapuser,
sappassword, "EN", saphost, sapsysnumber);
mConnection.connect();
mRepository = new JCO.Repository("GetLeaveRequestFlag", mConnection );
IFunctionTemplate ftemplate = mRepository.getFunctionTemplate(Z_BAPI_CHECK_LR_TO_APPROVE);
myFunction = new JCO.Function(ftemplate);
JCO.Field OBJECT_TYPE = myFunction.getImportParameterList().getField("OBJECT_TYPE");
OBJECT_TYPE.setValue("US");
JCO.Field USERID = myFunction.getImportParameterList().getField("USERID");
OBJECT_TYPE.setValue(p_userID);
mConnection.execute(myFunction);
JCO.Field leaveRequestFlag = myFunction.getExportParameterList().getField("FLAG_LEAVE_REQUEST_RECORD");
mConnection.disconnect();
But only catch here is that I need to create & maintain SAP logon credentials for a particular user manually.
It is not possible to single sign on connector user into SAP system (like its done above).
Any thoughts on this?
Thanks & Regards,
Amey

What is a gateway proxy?? what are synchronous and asynchronous calls?

bapis are rfc enabled. but are there any other rfc's available in sap? what is a gateway proxy?? what are synchronous and asynchronous calls?

This is a Youtube video that explains what you have (I assume you installed it somehow) on your computer:

For openers, I would uninstall any A/V software you have put on your system. It is certainly possible that that junk has put some other stuff on your computer.
I'm also afraid my computer might have been hacked?
Highly unlikely.
