JCO , Web Dynpro & SLD connection

Hi
Can anyone please let us know why do we need JCO, WebDynpro and SLD configuration. I trying to configuring EP/BI and EP/ERP (MSS/ESS) using SAP configuration guide but not sure what they are used for.
is JCO/SLD/Web Dypro is the requirement for EP/BI & EP/ERP configuration.
Thank you everybody

Hi
The SAP Java Connector (SAP JCo) allows a Java application to communicate with any SAP System.
It provides the bridge to fetch data across stacks and from different r/3 destinations.
check the following Link:

Web Dynpro Application connecting to incorrect R/3 instance

Hi,
We have newly configured EP.
We are facing strange problem with web dynpro applications.
They are accessing data from incorrect instance of R/3 system,i.e, if correct system instance is x , they are accessing data from y instance, on the same R/3 server.
We have checked JCO connections. SID in JCO connection is of the correct instance.
We have also checked SLD, but are not able to find out the root cause of the problem.
Are there any other configuration, settings required?Are there any settings required on R/3 side?
Can we some how track entire process from JCO to R/3?
What happens after fetching server details from SLD? Is there any other step before connecting to R/3?
Can anyone help on this?
Thanks in advance,
Apurva

Hi,
I have checked alias name (System ID) used in JCO connection.It is correct.
I have also checked System ID in SLD.
Is there any other configuration check required?
Thanks,

Web Dynpro application connecting to oracle

Hi all,
i want to create a web Dynpro application which will fetch data from oracle database.
Can anyboby guide me with some documents.
Thanks in advance.

Thanks for your quick reply!
I am trying in another way.I've created a WD application and in custom controller I've put the code for connection, copying the retrived data into context and trying to display the data in one view.
CODE:
DriverManager.registerDriver(
              new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection(               "jdbc:oracle:thin:@oracle server ip:port:sid",
     "user name",
     "password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from table");
if (rs != null)
while ( rs.next() )
     //code for copying data into context
stmt.close();
conn.close();
Error(No class defination found) is at first line i.e. new oracle.jdbc.driver.OracleDriver().
I've put classes.zip in lib and build path as well.

Web Dynpro resets connection when calling webservice

Hi,
I get a very very strange problem by using Web Dynpro to implement a webservice client.
The Webservice provider is running on a IBM WebSphere Server. I can use xmlspy to call this service and get the response correctly as expected.
But when my web dynpro application (running on WebAS 6.40 Stack 13) calls this webservice, I only get incomplete SOAP response message. It looks like the HTTP response had been broken beforte it finished. To verify this, I use ethereal to analyse the tcp packet. And I find that the WebAS server has sent some tcp reset packets to the websphere server, before the http response can be finished. This problem can be reproduced on different WebAS server. So it can'b be caused by hardware defect.
When I use web dynpro client to call other webservice on other WebAS server, there is no problem at all.
I have really no idea, how could this happen.
Thanks in advance.
Kanyin

Hi,
Now we know how it happens.
The reason is the content of the soap message from webservice provider is by means of the WSDL definition not complete, although the message structure is complete.
The Web Dynpro deserialise the soap response on the fly, without getting the complete SOAP message first. When the parser throws any exception, the connection will be broken by the WebAS.

Web Dynpro SLD - No Visual Admin for CE 7.1

I used NWA to configure an SLD, able to ping, Collect and Send, etc. - all is good.
But when I go into Content Administrator for Web Dynpro the SLD is undefined. How do I set it if there's no VA?

Never mind .... SLD_Client .....

Web dynpro - database connection

Hi all,
i intead to make a web dynpro application which will store the data entered by the user in an oracle database
How am i to obtain webdynpro - oracle connectivity?
points assured for Help

Hi Shobhendra,
The simplest way is to use Visual admin. For that , do the following
1.Run Go.bat in the server to open Visual Admin.
2.Select Cluster->JDBC Connector
3.In Runtime, Create a driver of any name(Say mydriv). Select classes12.jar for that
4.Create a new datasource(Say myDS). There specify the
driver class as oracle.jdbc.driver.OracleDriver
database url as jdbc:oracle:thin@IPADDRESS OF ORACLE SERVER:PORT:SID
driver as mydriv
The PORT will usually be 1527 or 1521.
For IPADDRESS, PORT and SID, u have to contact db admin
5. In additional , select Vendor or Native SQL
6. Test the connection using Monitoring tab. If green line is coming, then connection is successful, otherwise, the parametes u used will be incorrect
7.In ur webdynpro code, inorder to get the Connection to oracle, add the following
InitialContext ctx=new InitialContext();
DataSource ds=(DataSource)ctx.lookup("jdbc/myDS");
Connection con=ds.getConnection();
8. Press CTRLSHIFTO

Using ABAP Web dynpro for connecting EP with MDM

Hi All,
We have an architecture landscape in which EP User interface (iviews) need to integrate with MDM import manager. Is it possible to achieve this using Web dynpro? If any company has implemented this kind of scenario before, please gave us the tips.
Thanks,
Anand

Hi Anand,
You can use MDM Java API in WD. ABAP API for MDM is is currently in process.
Just wondering what kind of business scenario do you have which allows portal users to use import manager`s functionality.
Best regards, Maksim Rashchynski.

Web dynpro sld / jco setup

hi,
i have an erp system installed. on my local computer i installed the netweaver developer studio. i build the flights example from sap. after building and running the application an error occures:
The initial exception that caused the request to fail, was:

so, i want to configure the jco. but on the page where i can do it, it says that my sld could not be open. in the visual administrator i set the http settings. and i tried to open the sld in browser, but it says that i have no authority for this.
but i logged in with the j2ee admin, which i gave the sap_sld_administrator rights too.
do you know what went wrong?

Hi Marcus,
If you are using UID/PWD mapping for JCO destination please check wether you have provided correct uname and password.
If you are using SSO instead of UID/PWD mapping then check wether SSO is working properly between portal and ECC.
Mostly this problem is due to authorization failures during the logon phase.
Please check if the SAP user-id & password you are using to connect to the SAP system are correct.
Get the logon data from the JAVA application or JCo trace
for the error description visit,
http://help.sap.com/saphelp_nw04/helpdata/en/f6/daea401675752ae10000000a155106/frameset.htm
Have a look at the solution provided in the below threads :
1>Re: com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Incomplete log
2>JCO Error
Hope this helps you.

Web Dynpro application connecting to sql server

Hi,
I want to fetch data from SQL Server using webdynpro. Can anyone suggest me the steps to do this? I need to connect the SQL Server also to portal. I found one using visual admin another using system object in portal. Which is better way and how can use that connected system in coding to retrive data.
Please help me. Points will be awarded for helpful answets.
Thanks,
Raz

Hi,
You place the code where ever you want to establish the connection to the data base which is located remotely in a diffrent IP from NWDS.
The requirement for this we have 3 jar files.Which you have to copy in the lib folder.
those are:-
1.msbase.jar
2.mssqlserver.jar
3.msutil.jar
XX.XX.XX.XX->IP Address
XXXX---->Port no
Code:-
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
conn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://XX.XX.XX.XX:XXXX;databaseName=TrackingSystem","sa","sa" ) ;
Statement st = conn.createStatement();
String str = "select * from User Table";
ResultSet rs = st.executeQuery(str);
while(rs.next())
String str1 = rs.getString(1);
wdComponentAPI.getMessageManager().reportSuccess(str1);
Thanks & Regards,

Creation of JCO Destinations for web dynpro

Hi all,
I read quite a lot of post concerning the subject but unfortunately I did not found a solution to my problem.
My goal is to create JCO Destinations to make my web dynpro to connect to an R3 system.
In order to realise this I followed these steps :
- Launch visual admin and set http settings, rfc settings, and cim client settings. I click on CIM client test and the result is a success so I assume this part is correct.
- In R3, I execute transaction smgw, go to remote gateway to get the gateway settings. I execute RZ70 and filled the parameters just checked. Then I activate and launch the data collect. I have no error message and everythings seemed to work fine.
- In the sld (<host>:<port>/sld) I configured my server settings, the I go to data bridge, set update local sld to true and fill RFC gateway info with the same values as in my R3 system. Then I restarted the sld.
- Finally I went to Web Dynpro content administrator to create my destinations and there I failed. After entering all settings (the message server appears in my technical landscape in SLD), when I click on finish I've got the following exception :

I tried to create a generic destination (no for the web dynpro tutorial) and failed again.
I do not undestand what I did wrong.
Does someone have an idea ?
Thanks for reading this !

This thread helped me too because before reading it I didn't thought that I had to create a logon group "PUBLIC".
Anyway I succed in creating 'WD_FLIGHTLIST_MODELDATA_DEST' and the test is ok. The problem was that in sld / technical system / web as abap, my Central Application Server host was wrong. It is not possible to change it so I just add a secondary server with the right host and select this one when creating the destination.
The only pb remaining is now 'WD_FLIGHTLIST_RFC_METADATA_DEST'. I think the pb is my message server such this is the only difference between the two destinations
Thanks for your help

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.

Problem in connecting JCO destination in web dynpro

HI all,
I was installed sneak preview of Net weaver 6.4,
I want to do some web dynpro (java) programs which connect to back end systems.(R/3 system).
The R/3 system which I want to connect is at remote place, i have connectivity to that R/3 system using VPN connectivity. With this I am not having any problem. Since I am able to connect using User name and password, and able to do some transactions like RZ70, etc.
I developed an application which calls COMPANY_CODE_GET_LIST (BAPI function).
for the above requirement what I did was
(1)I created SLD setting.
(a)Web as Java (I am not having any problem to
Create this.
(b) Web as ABAP.
When i am trying to create
This, there are some steps like i need to go to SAP log in and I need to run the transaction RZ70. For this i need to create an enter in visual administrator>JCO RFC Provider>runtime-->Bundles i need to create an entry for RFC destination as well as Repository.
under RFC destination there are some fields which i need to enter those are (a)Program ID as mySLD (b) Gateway Host as 10.10.10.125 (c)Gateway service as sapgw00 (d)Number of processes as 1
Under Repository (a) Application server host 10.10.10.125 (b)system number as 00 (c)Client number as 100 (d)Language as en (e)user as ABCD (f)password as 1234
I haven't choused the check boxes Local bundle and Unicode and pressed the set button. So like this i created the RFC destinations. under the properties tab there is a property called RFC_DEFAULT_DESTINATION by default it was false so i made it as true. .
I also went to SLD Data Supplier,under Runtime tab , HTTP Settings , I mentioned
(a)Host: pava-vis75
(b) Port: 50000
(c) user: administrator
(d) password: abcd1234
RFC Settings, I mentioned as
(a)Gateway Host: 10.10.10.125 (which is SAP R/3 system)
(b)Gateway Service/Host: sapgw00
CIM Client Generation settings, as
(a)Host: pava-vis75
(b)Port (http/https):50000
(c) user: administrator
(d) Password : abcd1234
I tested the CIMClient Test by click the the button. I got the successful message.
Then I came back to HTTP settings and clicked the button with tilted arrow mark [This triggers data transfer to system landscape directory], for this also I got a successfully message.[data transferred successfully]
Next I been to SAPLOGON and went to RFC Destinations by using sm59 transaction. There under TCP/IP connections i been to SLD_NUC , opened this by double clicking that and under Technical settings for Program ID I had given the ID which I created at visual administrator [JCO RFC Provider] which is mySLD , under gateway options for Gateway Host as 10.10.10.125and Gateway service as sapgw00 then i tested the connection, it was also successfully.
Then I opened the SLDAPICUST and i created a new entry for maintaining the SLD Access Data by giving some couple of entries as
(a)Alias: vissldtest
(b)Host Name: pava-vis75
(c)Port: 50000
(d) user: administrator
(e) password: abcd1234
Then saved it.
Next I created sapmsUV0 3600/tcp entry at
WINDOWS\system32\drivers\etc\services file, and also there are some required entries which are already existing those are sapgw00 3300/tcp to sapgw99 3399/tcp , another entry starts from sapdp00s 4700/tcp to sapdp99s 4799/tcp , next entry starts from sapgw00s 4800/tcp to sapgw99s 4899/tcp and sapmsJ2E 3601/tcp .
I restarted the system, as well as server.
Now my problem is when I was trying to create JCO destination at web dynpro content administrator. For that I navigated as create JCO Destination Deployed Contentlocal-local/CompanyCodeGetList-Applications CompanyCodeGetList
I Choosed the JCO Connections tab- there are 2 entries those are
(1) COMPANY_CODE_MODEL
(2) COMPANY_CODE_RFC_METADATA
So I started creating connection for COMPANY_CODE_RFC_METADATA.
First one is
General data Name : COMPANY_CODE_RFC_METADATA
Client : 100
I didnt changed any default JCo pool configuration.
J2EE Cluster
There is a check box called Use Local J2EE engine J2E on pava-vis75 so I choosed that.
Connection Type
Dictionary Meta Data and application Data
I choosed the first one.
Then
Msg. Server Connection
Security
After these, I tried to test the connection by clicking the Test Connection.
It is saying the error as
First time
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=v011 GROUP=DEFAULT R3NAME=UV0 MSSERV=sapmsUV0 PCS=1 ERROR service 'sapmsUVO' unknown TIME Fri Jul 01 07:20:41 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1

Can any body please help me to solve this problem.
From past 1 week on wards I have been trying to resolve this. But in vain.

It does not necessarily mean that you have to change that parameter. I read that blog as I had a similar problem, and after reading it and understanding the reasons and possible causes for the error, I found that my particular problem was that I was using "PUBLIC" as the logon group in my JCO destinations, but such a group does NOT exist at my backend. I went to transaction SMLG, had a look at Logon Groups, noted that there were none other than SPACE, figured out that I had to include that information in SLD (Web AS ABAP tech. system --> Message Server --> Logon Groups), put it there. Voilá. It works.
Edit: That SPACE logon group is the one I had to use at JCO destinations. Sorry I forgot to mention that one...

Eduardo.

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)

Web dynpro console - monitor - JCO Connection pools

If you go to the web dynpro console -> monitor -> JCO connection pools you see a table with information.
JCo Clients MonitorJCO Pools - 12:31:02.992
Name Size Currently used Maximum used Max.connections Max.pool size
Can somebody explain what for example the "Size" and "Maximum used" mean in this table?
And if you have set max.pool size to 20, what things can override this setting in the SAP system?
