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.

SAP Java Connector: Is it possible to cut field values of extracted table?

I am extracting some SAP tables using the SAP Java Connector (via RFC_READ_TABLE or similar). Is it possible to pass some kind of maxlength for some fields of a table, e.g. if we have a field with size 3750 (like PROFS in table USH04) but I only want the first 100 chars - something like LEFT(PROFS, 100) in SQL?
Thank you for your helpful response!

Hi.
The point is that PROFS has a size of 3750 - but RFC_READ_TABLE will only extract data up to 512 chars per row.
Kind regards

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

Sharing the Metadata Repository (SAP Java Connector)

Is it possible to share the metadata repository across multiple client processes in the context of the SAP Java Connector? If so, can someone point me to the technique that I have to implement?
Each client process creates its own JCO.Pool (with a unique key) and obtains a repository by invoking JCO.createRepository(...).
Thanks in advance.

Hi jim,
You will probably find the answer in this article :

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.

How to install the SAP Java Connector

Hi,
I am unsure how to install the SAP Java Connector on Linux (Suse Linux Enterprise 10). The SAP Integration Kit install and admin guide says:
===
u2022 Copy the librfccm library and the libsapjcorfc library to busines
sobjects_root/enterprise120/PLATFORM_PATH, where busines
sobjects_root is the full path to your businessobjects directory,
and PLATFORM_PATH is your platform. For example, PLATFORM_PATH
is solaris_sparc for an installation on Solaris.
u2022 Use symbolic links for the location of the librfccm library and the lib
sapjcorfc library.
u2022 Add the location of the librfccm library and the libsapjcorfc library
to the library path.
===
Do I have to do all 3 steps or is the 1st one (copying of files) enough?
On the other hand, the SAP Java Connector guide says:
===
Then add {sapjco-install-path} to the LD_LIBRARY_PATH environment variable.
Finally, add {sapjco-install-path}/sapjco.jar to your CLASSPATH environment variable.
===
So, what to do?
Thanks!

Thanks for your help. So i copied the 2 files as mentioned in point 1.
Where do I have to copy the file sapjco.jar to? There is no shared lib folder after installing BO Edge 3.1 on a Linux system.
I copied the sapjco.jar to /bobje/tomcat/common/lib but still get the message that the Java Connector files are not in the correct directory.
I already copied the files librfccm.so and libsapjcorfc.so to /bobje/enterprise120/linux_x86 .
Thanks again!
Edit: problem solved: Copying the sapjco.so to tomcat/shared/lib is correct, if the directory doesn't exist then just create it (mkdir). The message is just plain information 7 hint.

I'm trying to intergrate BO and BW using SAP BO Integration kit, and following the manual at http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/a00ee3b2-5283-2b10-f1bf-8c6413e0898f&overridelayout=true
But first i must install the SAP Java Connector, I have downloaded them from https://websmp107.sap-ag.de/~form/sapnet?_SHORTKEY=01100035870000719346&.
My server is a WMvare win 2008.service pack 2.
My problem is that i'm unable to register the sapjco3.dll file.
I'm runnning the comand regsvr32 "C:windowssyswow64sapjco3.dll
but I only get the error message "The module "sapjco3.dll" was loaded but the entry-point DllRegisterServer was not found. Make sure that "sapjco3.dll" is a valid DLL or OCX file ant try again"
I hav tried both the 64 bit and the 32 bit version of the dll. same error.
the dll version is 7110.34.16.7531
Any ideas

Hi Pal,
you need to use the Java Connector v 2.1.8 and there is no need to register the DLL.

Call 'SAP Java Connector'

Hi,
has someone integrated in Forms 9.0.4 the call to the 'SAP Java Connector'?
If yes, do you have an HowToDo or a ProfOfConcept?
All Tipps and Tricks are welcome.

You probarbly already solved the problem but to others who run into the same problem add the following to the reference.txt file on the server: "reference service:eisconnector library:com.sap.mdi"
The reference.txt is located on the path "..\usr\sap\EP60\j2ee\j2ee_00\cluster\server\managers"
Depending on the portal version a reference.txt might be located on the state controller as well. In that case modify the reference.text on the state controller instead, restart the portal as verify the reference.txt on the server has been add the reference.

I'm not sure if 4.6 is (should be) but 4.8 is definitely UC compatible.

The previous reply is not correct - ABAP can call Java! You could have a look at the following links:

Is this possible in java ?

myObject.add(new myAnotherObject().setAttr("foo") );

myObject.add(new myAnotherObject().setAttr("foo") );Regarding the expression �new myAnotherObject()�,
Is myAnotherObject the name of a class or interface? Or is it a reference to an object?
Is this what you have in mind?
class MyObject {
void add(MyObject o) {}
void setAttr(String s) {}
MyObject myObject =
MyObject myAnotherObject =
The keyword new requires a class or interface name not a reference to an object.
Perhaps, did you intend to say �new MyObject()�?

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