Java Connector (JCO) desupported?

Dear all,
does somebody know whether the Java Connector (JCO) will be desupported and if so when?
I would like to use it in a new project because it may be easier to introduce than the whole XI infrastructure.
But if there is an official desupport notice I have to switch my strategy.
If this may be the wrong forum please advise me to the right one.
Thanks in advance,
Frank

As far as I know,JCo is needed for the communication between ABAP stack and JAVA stack.In XI , ABAP stack and JAVA stack are mandatory and you need JCo.
"I would like to use it in a new project because it may be easier to introduce than the whole XI infrastructure."
Can you be a little more clearer abt what u mean by the above statement.

ABAP to Java Connector (JCo)

Hi All,
Currently this is what I have:
ABAP program uses OPEN SQL of course collect information from SAP database, then using NATIVE SQL goes thru DBCON to transfer information directly to another application (Non SAP system) database (not SAP database).
I just dont like this idea anymore since I was reading about the Java Connector.
So what I want to do is...Not sure feasible this is where I need your help on:
Remove all my NATIVE SQL statements, use JCo and rewrite those statements in Java language and communicate to the Non SAP application thru their API (their API is also Java base)
Will reward points.

You simply have to have a connection with SAP system and then you can call BAPI with which you can read / update the data in the SAP system.
Hope this info proves useful.

Java Connector (Jco) sizing in a NW2004s cluster

Hi All,
We have an EP7 cluster with 3 x SAP J2EE engines (multiple dispatcher and server processes running on multiple hardare). I am looking at sizing the Jco connection pools for ESS and MSS applications. This will involve changing the parameters against the Jco connection destinations - like 'maximum pool size' and 'maximum connections'. My question is, if for instance I was to change the 'maximum pool size' from the default value '5' -> '50', being that we have 3 J2EE engines, does this mean that potentially we could have 150 (3 x 50) connections allowed to the backend ABAP system ? Or are these settings global ? I can't seem to find a definite answer to this.
Thanks for your time,
Regards
Anthony

DI Java Connector

Hello All,
First of all i have to say that im sick of searching abt this.......so if anyone can help it'll mean a lot to me. im trying to connect to SAP Business One from Java, in the SDK help file it says that i can connect to B1 through DI API, but how can i do it with Java???...........it says to use "SAPbobsCOM67.dll" file to connect with java....how can i do this??........and it says it includes the packages "com.sap.smb.sbo.api" , "com.sap.smb.sbo.util" , "com.sap.smb.sbo.wrapper.util" but i cant find it......i downloaded the SAP JCo 2.0 too from SAP Service Market Place....but it only has classes to connect to SAP R/3 System. What i need to do is connect to Business One with pure Java Code........using those class packages i listed above....but i don't seem to find it on the internet.....somebody pls help me on this.....because im not into VB .Net.... Thanks.

Hi Malinda,
You have to install the DI API and the SBO SDK to have the Java Connector (JCO)libraries and to have the JCO help file.
In basic the API is the same as with .NET, but there are some differences.
You can scan this forum for some samples.

Additional runtime license fees per user in order to use the Java connector

Hi All,
I have one question.
Do we require to pay additional runtime license fees per user in order to use the Java connector (Jco) supplied by SAP?
We're currently not using the Jco but are looking into the possibility of using it.
Thank in Advance.

Hi All,
Please answer my question
We need to use Jco to connect to our 4.6C SAP production system. We do not have Portal or any other components. It's just a plain 4.6C system, service pack level is 23.
We are currently paying license fees for using the system on a per user basis.
Thank You.

Thru Java connector to update SAP by BAPI

Dear...
How to bring the data from external application through the Java connector to SAP? Pls help....

Hai Check the following Document & Links
Bapi to create customer master
BAPI_CUSTOMER_CREATEFROMDATA
BAPI_CUSTOMER_CREATEFROMDATA1
Or you can use FM SD_CUSTOMER_MAINTAIN_ALL
what is BAPI?
BAPI stands for Business API(Application Program Interface).
I have answered this question before..
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

Java Connector(JCO) can call not only BAPI's but also the function modules which are remotely enabled..
BAPI's as i said earlier are remotely enabled function modules..
Hence, JCO can call also BAPI's(n not only BAPI's as u mentioned).

IPV6 support by SAP Java Connector (SAP JCo)

Hi there,
Does anyone know if IPV6 is supported by SAP Java Connector (SAP JCo) ?
Thanks

See http://help.sap.com/saphelp_nwmobile71/helpdata/en/46/cd5ee2c45365dde10000000a155369/content.htm

JCo( Java Connector)

Hi Guys,
Any one give some info abt JCo( Java Connector). Thanks in advance.
Thanks
Kiran.B

Hi Kiran,
Check the following example
SAP Java Connector - Excample 1: Simple RFC call
Scenario
We will call the RFC function module ZNAS_HIE1_GET_MEMBER_FARM.that returns members that have owned a farm. Input to the function is a farm number, and output is a table of members that have owned the farm and Owner number (Sequence number of owners).
Class testJCO is excuted and calls class GetMemberFarm method GetMemberFarmFromSap. Input parameters to GetMemberFarm are Farm and Owner number.
GetMemberFarmFromSap executes RFC ZNAS_HIE1_GET_MEMBER_FARM, that returns a table of members that have owned the farm from the input parameters.
GetMemberFarmFromSap loops through the table and finds the member where ZZCHCODE (Owner numer), is equal owner number from the input-parameters. and returns the member.
Code
Class testJCO
public class testJco
 public static void main(String[] args)
 GetMemberFarm testGetMemberFarm = new GetMemberFarm();
 String memberFarm= testGetMemberFarm.GetMemberFarmFromSap("0111020155","02");
 System.out.println("Memberfarm: " + memberFarm);

Tips and tricks for the Java connector
How to set and import parameter - Field
Give the import parameter SALESDOCUMENT the value "00006973":
JCO.Field SalesDocumentField = jcoFunction.getImportParameterList().getField("SALESDOCUMENT");
SalesDocumentField.setValue("00006973");
How to handle an import parameter - Table
JCO.Table ORDER_PARTNERS = jcoFunction.getTableParameterList().getTable("ORDER_PARTNERS");
ORDER_PARTNERS.appendRow();
ORDER_PARTNERS.setValue("AG","PARTN_ROLE");
ORDER_PARTNERS.setValue("0000001032","PARTN_NUMB");
How to handle an import parameter - Structure
JCO.Structure order_header_inx = jcoFunction.getImportParameterList().getStructure("ORDER_HEADER_INX");
order_header_inx.setValue("I","UPDATEFLAG");
order_header_inx.setValue("X","DOC_TYPE");
How to handle an export parameter - Table
JCO.Table myTable = jcoFunction.getTableParameterList().getTable("STATUSINFO");
for (int i=0; i < myTable.getNumRows(); i++)
myTable.setRow(i);
// Retrieve the value of the field DOC_DATE
oDocDate = myTable.getField("DOC_DATE").getValue();
How to handle BAPI return table
Meesage type and message is stored in vector bapiReturn.
Vector bapiReturn;
JCO.Table jcoReturn = jcoFunction.getTableParameterList().getTable("RETURN");
 for (int i = 0; i < jcoReturn.getNumRows(); i++)
 { jcoReturn.setRow(i);
 String Message = jcoReturn.getField("TYPE").getValue() + " " +
 jcoReturn.getField("MESSAGE").getValue();
 bapiReturn.setSize(i + 1);
 bapiReturn.setElementAt(new String(Message),i );
Using COMMIT
 try
 { // Get a function template from the repository
 IFunctionTemplate ftemplate = mRepository.getFunctionTemplate("BAPI_TRANSACTION_COMMIT");
 // Create a function from the template
 jcoCommit = new JCO.Function(ftemplate);
 if ( jcoCommit == null )
 // Do something..;
 catch (Exception mException)
 { mException.printStackTrace(); }
 // Execute COMMIT
 try
 { sapConnection1.mConnection.execute(jcoCommit);
 catch (Exception mException)
 { mException.printStackTrace(); }

SAP Business One - Java Connector

Hi All,
 
We have a SAP Business One Application installed on a laptop. The requirement is to be able to use the SAP Java API to update tables in the system. We are not allowed to connect directly to the database and was advised to use the API instead.
 
The downloaded API that we are using is "sapjco30P_6-10005324 32 bit.zip". I have included the dll file contained in this package in the WINDOWS/system32 folder. I am using Eclipse as IDE and already included the "sapjco3.jar" in the classpath.
 
First question: Am I using the right Java Connector for SAP Business One?
 
I got sample code on how to connect using JCO:

Please help.

Hi, 
Thank you very much for the reply. I am now able to move forward with what I am doing. 
I used the following code in connecting but am encountering an error:

 } catch (Exception e) {

 return -1;
 return rc;
 public void freeConnection(){
 company.disconnect();
} 
I am getting the error "Failed to Connect to SBOCommon -111". 
Error is still the same even if I set UseTrusted to true and comment the DbUserName and DbPassword. 
Do I need to specify the license? Or login to SAP before connecting? 
Thank you.

Is this possible: SAP Java Connector - XI - R3 with XI RFC Adapter?

Hi,
I try to call a RFC on a remote R/3 System over the XI Server in a Java Application with SAP Java Connector.
I have configured a RFC Sender Adapter in XI. I get the
following Exception:
"lookup of alternativeServiceIdentifier via CPA-cache failed for channel 'SenderChannel_RFC"!
Is this scenario possible? Or do the connection from
a SAP Java Connector App to the XI RFC Adapter not work?
You can't set the Client and System ID of a Third-Party or
Standalone Java system in the SLD.
Thanks for any help!
Regards
Wolfgang

Hi,
We use a JCO for directly connecting to sap systems.
In that case we need not use any XI also.
But if you want to use RFC adapter and java application the best way is to use java proxies as sender and reciever as RFC adapter.
I donot think there is any architectural significance in using rfc adapter of XI while using JCO.
Let me know if I mis-understood the context.

Hi Friends,
In the code ....
I am calling Remote Function module ZRFC_PO_VEND_VALID using java connector and passing PO_Number and Vendor Number as input parameters and after execution it returns (E_POVALID =1 [PO_NUMBER exists for Vendor number] otherwise E_POVALID = 0 )
when i am executing the below code ....in both cases it is returning Zero value.
I tested the function module in se37 its working....
may i know the reason for this....
import com.sap.mw.jco.*;

Integrating SAP Java Connector with SAP XI

Hi XI experts
We are about to integrate our SAP ERP2004 system with a new WMS system. The vendors of the WMS system normally integrates with ERP directly through SAP Java Connector, but we would like to put SAP XI between the two systems so we have good way of monitoring the messages beeing sent.
I would like to make a synchronous test scenario where we send a ARTMAS idoc from SAP to XI which sends it to the WMS. After WMS system receives the ARTMAS Idoc it sends an acknowledgement back to XI which passes it on to SAP.
The integration would then look like this:
SAP ERP <-> SAP XI <-> WMS (Jco)
Is this scenario possible? And if so, how would you suggest to set it up?
I was thinking of using the RFC adapter to connect to the Java Connector of WMS, but am not sure if this is the right approach or how it should be set up.
Any help or comments would be greatly appreciated.
Best Regards
Chris

I have made a setup like this:
SAP <-> XI <-> WMS
The Scenario is like this:
SAP sends an ARTMAS03 idoc to XI which maps it directly to the same ARTMAS03 idoc structure (need a few changes in the future so thats why im not using IDOC tunnelling) then it uses a RFC receiver adapter to connect to our SAP gateway, where the WMS is registrered through JCO.
When I first sent the idoc, i got a "RfcAFWException: failed to read funtionname from XML document: missing namespace declaration(2)" then after reading Q23 in note 730870, I used the RFCNormalizer xslt to change the namespace to a "urn:sap-com:document:sap:rfc:fuctions" instead of the "urn:sap-com:document:sap:idoc:messages". The error is now "functiontemplate from repository was <null>".
As far as i can see the error is because the metadata repository defined in the RFC adapter cant find the function module that normally would be in the root of a RFC-XML. But I dont know how I can send an Idoc through the rfc adapter to the gateway then. Anyone got some ideas?
Thanks
Chris

Java Connectors

Hello Experts,
We have a real time requirement for getting data from r3 to bi and none of our data sources are delta enabled.
So we are planning to use java connectors for this. I found that the SAP Query Connector could report realtime from BI or R3. But we need something which gets data from r3 to BI.
Can you please lead me by guiding me towards the connectors that could be used for getting data from r3 to bi realtime?
thanks,
Sri.
P.S. I promise to award points for helpful answers. Thanks Again!

use jco interface to get data from r/3

Download Sap Java connector

Where can I download sap jco?

Hi Alfonso !!!
You can navigate through http://service.sap.com/connectors
it's the place for all kind of SAP Connectors family.
So, under the option *Overview choose SAP Java Connector link, at this point the left navigation menu will be wide open, so the last step is be able to find there the option "Tools&Services", the page with title Tools & Services: Support and Release Strategy, License Terms, Software Download will be opened, there is the place where you can find all versions of JCO for all supported OS.
Be sure you also have an "SS" user (Sap Service User like SXXXXXXXXX) to certify your access to this link.
