Settings SLD and JCO connection for Java Web Dynpro

Hi BI Gurus,
I'm a Business Intelligence newbye and I'm a bit confused about Web Dynpro configurations.
I try to execute, through Netweaver Developer Studio 7, a simple java Web Dynpro who call the standard Flight List BAPI.
My configuration is: NW 2004s installed on BI server (with java instance and j2EE Server) and Flight List BAPI stored on R/3 ECC. 5 System in another server.
Now, my doubt are:
1) in SLD Data Supplier (J2EE Visual Admin on BI Server) CIM configuration, what are the connections parameter necessary?The BI host or R/3 host?
2)if I set BW system parameters in SLD and in NWDS when I try to run my simple web dynpro an error occour This is the output:
The initial exception that caused the request to fail, was:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_FLIGHTLIST_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
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.
Additional information about the System Landscape Directory and the Web Dynpro Content Admin can be found in the SAP Developer Network (SDN) and in the Online Help for the SAP Web Application Server (installed with SAP NetWeaver Developer Studio and available online).
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.
3)where can I create new JCO connections?What are the requirements settings?
I am always available for answers about the post!!
Help me please!!
Thanks thousand and sorry for my incorrect english!!

Andrea,
You can Create the JCo destination from Content Administrator. You must login as Administrator.
use the link as
http://<server>:<port>/webdynpro/welcome/Welcome.jsp, select Content Administator->Create JCo Destinations/Maintain JCo Destinations.
Please have a look on the following links regarding creating/maintaining JCo destinations. The are usally asked questions regarding JCo destinations.

Can we use JCo connection with non-Web Dynpro J2EE project in NW

With Web Dynpro, we have the RFC wizard to call RFCs using JCo connection. I am wondering, if I create a J2EE project in NW development studio, can I and how to use JCo connection to call RFCs?
Thanks.

yes, of course.

JCO Connection for web-dynpro tutorials (EP 6.0 SP9 downlaod from SDN)

Hello,
I have a question regarding JCO connections for web-dynpro example/tutorials. I have installed WAS 6.40 sneak preview from EP 6.0 SP9 download from SDN. Installation instruction says: Choose "No SLD available"
but the web-dynpro example/tutorial asks to create JCO connections by going to web-dynpro -> content admin..etc on http:<host>:50000..Here, all the tabs relating to creating JCO connections appear to be "protected" on my screen. so I can't do anything further. By going to http:<host>:50000/sld, I also tried to add SLD server..but that is not helping. There is some "import" button, but which CIM file (in which folder etc) am i supposed to import for a simple test system? What are the steps for a bare minimum setup so that I can use the WAS 6.20 system at work-place as my backend & try out the web-dynpro examples? Do I really need SLD setup? Where is documentation about all this after one installs the WAS 6.40 JAva? I was expecting it somewhere at least in the eclipse IDE help-documentation..None of the web-dynpro tutorials explain this !
thanks

Thanks everybody.
NagaKishore, after doing all the steps, when I goto
localhost:50000-> web dynpro -> content administartor, and try to "maintain JCO Destinations" I am getting this error: (full stack trace not included)
An error has occurred:

Connecting to R/3 System through Java Web Dynpro forms.

Hi,
I have a requirement in which I have to send data to R/3
from Java Web Dynpro screens.
I will design the Java Web Dynpro screens and write a RFC Model.
I will write a RFC in se37 which will connect to the RFC Model.
Before creating the RFC in se37, I will create ztables in se11.
I will write a ABAP Report to see that all data enters the ztables.
I need some guidance with regard to this.
Do, the RFC Model have the access of the ECC(R/3) System.
What are tasks to be told the Basis guy so, that RFC being called from through Java Web Dynpro?
Please provide me some documents with regards to this scenario.
Regards
Neha Singh

Hi Neha,
The steps you provided is clear enough to connect to a R/3 system through the WD forms.
On creating the model you need to give two inputs such as
logical system name for model instance
logical system name for RFC metadata
there will be 2 default values, also you can create your own JCOs in the <servername>:<port>/devinf of the server or u can ask your basis team also.
Before creating the JCO , the SLD (System Landscape Directory) needs to be configures, that your basis team will know.
other than that once you create the functional module in se37 make it RFC enabled , and once you import the RFC model , you can give your ECC system user name and password and search for RFC you have created from the list of RFC.

Sam Charles J.

How to setup Proxy for Java Web Start App ?

I'm having trouble getting Java Web Start to work.
at... http://java.sun.com/docs/books/tutorial/uiswing/14start/compile.html
It tell me...
To test whether your browser can launch an application using Java Web Start, click this link.
http://java.sun.com/docs/books/tutorialJWS/uiswing/14start/example-1dot4/HelloJWS.jnlp
I do that & see Java Web Start try to start but get message...

Then... http://java.sun.com/docs/books/tutorial/information/javawebstart.html tells me...
"This situation usually happens when your browser and your copy of Java Web Start have different proxy settings."
I click Start | Programs | Java Web Start | Java Web Start,,, then click File | Preferences | General
My choices are... Proxies: None User Browser _ Manual (User Browser grayed out)
If _ Manual checked then I get...

I'm running XP Pro via Wi Fi to a Linksys Wi Fi router to a cable modem... I'm also running Zone Alarm (tried turning it off but no luck)
I don't know how to set up the Proxy stuff... can any one please help me get this set up.
thanks - Will

OK, on my XP Pro system I went to...
Start IE -> Control Panel -> Internet Options -> Connections -> Lan Settings -> Proxy Settings
This is my 'Local Area network (LAN) Settings panel...
- user Proxy server for LAN is checked
- Address is blank
- Port is blank
So do I plug something in here... the ip address of my linksys wi-fi router and a port number or what?
My Java Web Start Preferences won't let me click 'Use Browser' only None or Manual
If I click Manual, I don't know what to plug into the HTTP Proxy and HTTP Port fields...
I tried the ip address of my router... thinking it may have a built in Proxy Server... and port 8080 as indicated by the Help page for the Java Web Start... but no luck.
I really appriceate any help on this...
thanks - Will

Hello Rajendra,
Good to hear from u. Let me try to give a soln for this problem of yours.
I think probably the logon group has not been specified in the backend.If thats the case then do the following:
Connect to the backend server for which you are trying to create the JCO. Run the transaction SMLG. It will show u the existing logon groups. carry out the following steps if the 'PUBLIC' group is not present in the list of logon groups.
Click on the create button. In the pop-up, type the logon as 'PUBLIC'. For the instance, select the F4 help and choose the existing instance number. Click on copy and click save. Try running the transaction /nsmlg and now it should show the logon group 'PUBLIC'.
When you create the JCO connection, it should now show the logon group 'PUBLIC'.

Prathamesh.

Do i need a network card to install and run a local java web server

Friends,
Do i need a network card in my computer to install and run a local Java Web Server or any Web Server.

network cards are only for connecting equipment together... you can set up a webserver without any more equipment than you have already! Indeed Tomcat... BUT you would be better off with apache for production stuff. It depends what you need to serve... if its mainly static pages (i guess it probably isn't) then apache will be enough by itself; but if you need to serve dynamic pages (JSP, Servlet blah blah) then you will need tomcat. Tomcat has it's own webserver and its perfectly ok for testing or low-load stuff, but you can integrate with Apache (a moderately compex task, but do-able, see tomcat-user forum off of apache site) for greater stability, and you don't have to show the port in the URL... Don't set up a webserver on any pc that contains stuff you don't want hacked into... it becomes very succeptible when the service is up...

JCO connection for Meta Data fails

Hi,
I have installed the WebAS Preview version with SP9. I had installed it once and had succesfully configured the JCo connection to my R/3 system. After I re-installed the WebAS after a system format, I have configured the JCo for both model & metadata. Both are configured to connect to the same R/3 sytem with the same user/password combination. But the JCo connection for model data pings and test come OK. But the one for metadata fails (ping as well as test).
I have tried creating more JCo connections with different names, but again the model one works, but not the metadata one.
Can anyone figure out why this is happening?
Regards,
Sumith.

Hi,
The error that I get when testing the JCo connection is:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=ltilsap GROUP=PUBLIC R3NAME=LTI MSSERV=sapmsLTI PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR service 'sapmsLTI' unknown TIME Fri Jan 21 16:37:40 2005 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 MODULE ninti.c LINE 494 DETAIL NiPGetServByName2: service 'sapmsLTI' not found SYSTEM CALL getservbyname_r COUNTER 1
and when I ping it gives:
Failed to ping JCo destination 'LTI_WDMETADATA_DEST'.
But the connection for model data works perfectly for the same set of configuration.
Thanks & Regards,
Sumith

JCO RFC provider and JCO connection

Hi all:
Please share your thoughts on the following doubts I have. Thanks.
1. To my understanding, we use JCO RFC provider(define in Java side) and RFC destination(in SM59) when we have request from ABAP to Java side. Then we use JCO destinations(define in Web Dynpro Content Admin) if we have request from Java to ABAP. Is this correct?
2. When creating the JCO RFC provider service, why we need to create those entries for repository for example, the server name, the user used to log into repository? What is the repository used for?
Thanks!

Hai,
your understanding of JCO RFC and RFC Destination is right.But JCO Destination gets the metadata and model data from ABAP,thats what we mention the Dictionany meta data and Application data while creating them.
Yes, we need to mention the application host,sys no,client and userdetails while creating the JCO RFC provider,then only it will fetch the data from that host and that particular client.
Thanks and Regards,

ESS Business Package for ERP 6.0 is a ABAP or JAVA Web Dynpro

Hi,
We are trying to implement ERP 6.0 and ESS with the Portal.
Is the ESS business package a ABAP or JAVA Web Dynpro????
Thanks.
Regards,
Mike

Hi Mike,
ESS BP is a portal content (runs only on portal runtime) which can only be deployed and run on SAP J2EE server (So it is java based).
http://help.sap.com/saphelp_erp2005/helpdata/en/f6/263359f8c14ef98384ae7a2becd156/frameset.htm
From EHP2 for ECC 6.0, you have an option choose ABAP WebDynpro for Travel related services. However, the portal content (iViews) is still on SAP J2EE server.
Thanks

JCo connection for the application data

Dear All,
Now, we configure BP for MSS. When we set JCo connection for the application data, from this link http://help.sap.com/saphelp_erp2005/helpdata/en/29/d7844205625551e10000000a1550b0/frameset.htm we selected the method "Ticket".
When we run the page in "Team" area, we found some errors as follow:
- You do not have the authorization to start service sap.com/pcui_gp~isr/IsrStatusoverview
- You do not have the authorization to start service sap.com/mssreccand/CandidateStatusOverview
- Pages about "Employee Information" display Blank iViews.
But if we set JCo connection for application data by using "User/Password" method (UserID have "SAP_ALL" profile in back-end system), the application work fine.
Kindy advise us which method should be used to set JCo connection (Ticket or User/Password).
If the method should be "User/Password", please advise authorization and user type for UserID that be used to map JCo connection.
Thank you very much,
Anek.

yes, that's the only decent book covering most of the exam curiculum (but NOT all of it, check the exam specs versus the book content to know what you are missing).
I'm working on the same material, and boy is it a lot...
Dry, boring stuff most of it.

JAVA, JAVA WEB dynpro and possibility of JAVA workflow

Hi all
Just a take here -- I'm just getting some feelers on the way WF SHOULD be going in future.
Since starting to use the JAVA WD system and netweaver developer studio it seems that having to encapsulate a lot of NEW Workflows as ABAP objects is going "Backwards". (Note I said NEW not EXISTING applications)
I understand that some compatability with existing systems needs to be maintained but if your user is doing all his applications from a Portal you really need the WF's to be triggered from the portal via say WEB SERVICES.
I find I'm actually using the older ERP / ECC 6.0 R/3 systems these days purely as DATA repositories and from a JAVA program can often retrieve the data via standard BAPI's and RFC calls in a JAVA or Portal application.
Isn't it about time that the workflow system as a whole was made much more JAVA and PORTAL friendly --since this is where more and more people are doing their developments from.
Since switching more or less full time over to JAVA WEB DYNPRO developments the whole development time is completed MUCH QUICKER and with many many less mistakes.
ABAP Web dynpro is also OK but it's still a little bit of a nightmare compared with JAVA when you need a lot of WEB SERVICES.
Some WF's obviously will need to remain ABAP based but newer custom WF's IMO should be WEB DYNPRO and WEB SERVICE based.
I can't think of too many large organisations who aren't making more and more use of Portals these days -- so C'mon SAP -- provide some proper Web hooks into WF's instead of us having to go through hoops and rings of writing LAST CENTURY's code to get stuff to work through a Portal.

Hi,
Have you checked the new BPM tool that SAP is offering? I think that it is definately a big step into to the drection that you are describing. I haven't really checked all its features and the technology that is is based on, so I am not the biggest expert of this matter.
Check for example this article to get an overview: http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b06c49b2-ac63-2c10-3d8d-d17b817ba4ca?quicklink=nw-bpm&overridelayout=true
Of course it will be a long road before this new tool will (if it will ever) replace the old ABAP based workflow engine.
I wouldn't totally agree with all the points that you presented (ABAP WD being a nighmare, etc.). Actually I think that the direction (at least in some parts) is the opposite. For example SAP seem to have replaced their "old" travel management applications (Java WD) with new ABAP WD applications, so I see that they believe more in ABAP than Java (of course there might be some financial & other reasons behind this also.). In my opinion WDA has so many advantages compared to WDJ, that I would consider carefully the options when choosing the technology (the possible better(?) compatibilitly with web services might be one of the reasons).

Karri
