Problem in JCO Connection
I have installed SAP Netweaver Sneak Preview SP18 and getting the following error message while configuring the JCO. Any clue????
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=uucf05h0 GROUP=PUBLIC R3NAME=GHD MSSERV=sapmsGHD PCS=1 ERROR service '?' unknown TIME Tue May 29 16:17:50 2007 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1
Hey Saket,
that means one of two things:
1. GHD is down
2. Your SLD configuration is incorrect
Please award some points:-)

Problem with JCo Connection Pool
Hi,
I have a problem with using an RFC Model in my WebApplication. So sometimes the access to the function block works, and sometimes it doesn't work. Now I know, that there is a problem with the connection pool. Look at this message:
com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool WD_X24_MODELDATA_DEST_CPIC_REKTO_DE_useDefinedUser is exhausted. The current pool size limit (max connections) is 10 connections.
So it looks like a problem with closing the JCo Connections after using. Do know where the problem is? Because I'm using many other function blocks with no problems.Hello,
You need to increase the pool size via Visual Administrator.
Server 0 -> Services -> JCO RFC Connections.
Change the pool size from there. I believe a restart is in order.

Problem create jco connection in webdynpro application run time
Hi There,
I created webdynpro application using rfc model.
After deploy the project , i created two jco connection
for data & meta data this is work o.k (test with no errors). the sld is o.k.
We are using application server (Single Server) for data
& message server for meta data (Load Balance).
During run time there is an error message:

<u>Can some one help me with this matter?</u>
Best regards Nir Shohat.Hi Nir,
We also had same problem but no we won't. Check ur config on SLD again and the try to the test connection from the http://localhost:4444/webdynpro ( WAS 6.4 )server.
If this connection is OK then deploy some small application n see.
Is ur's JCo connection working for J2ee application?

Problems creating JCO Connections
Hi experts,
I have a question regarding the JCO Connection creation in Content Administrator.
My first doubt is if it's necessary to create each JCO Connection for each backend system that I'll run RFC functions?
If is it true, during Creation I must specify user and password. I have to specify the Backend User and Pass, right?
Finally, could you explain me why there are several JCO connections created?
When I create the JCO connection I will be able to invoque Backend RFC functions from, for example, a webdynpro?
Kind Regards,
Martin.Hi Martin,
1. Yes, provided you want to use the RFC functionality.
2. Yes, you would be giving the username and password for the metadata.
Please refer to [Creating JCo Destinations|http://help.sap.com/saphelp_nw70/helpdata/EN/3a/3b1b40fcdd8f5ce10000000a155106/frameset.htm]
3.Generally, when you install business packages like ESS MSS etc, there are a bunch of JCO which are installed as well, but all you would have to do is edit its properties and point them to the correct location.
4. Yes, you can.

Hi Experts,
This is not related to Java Web Dynpro directly.
We are encountering strange behavior with respect to JCo Destination.
Up to yesterday we had no problems with JCo. But when we tried to run run a Web Dynpro application, it
was not able to extract data from SAP backend.
On further investigation it was found out that JCo Destination test is failing. Following is the error when we
tried to test JCo Destination:
com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Client 100 is not available in this system
Backend is working fine with username and password in the client. Connection from ABAP server to
the the problematic ABAP server is also working (SM59). But connection from any Java portal to ABAP
server is not working.
Has anybody encountered this problem?
Best Regards,
PramodHi Promod,
It would be some Username and password issue. If you manage to change them you issue will be resolved. Have a look at the the following useful discussion. It would be helpful for you.
JCO Connection Error
Also have a look at the following Wiki for troubleshooting the RFC Communication problems with Java Connectors.
https://www.sdn.sap.com/irj/scn/wiki?path=/display/ep/troubleshooting%252bsap%252bjava%252bconnector%252b(JCo)
I hope this helps you.

JCO connection problem at web dyn pro
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 <b>RFC destination </b> there are some fields which i need to enter those are (a)Program ID as <b>mySLD</b> (b) Gateway Host as <b>10.10.10.125</b> (c)Gateway service as <b>sapgw00</b> (d)Number of processes as <b>1</b>
Under <b>Repository</b> (a) Application server host <b>10.10.10.125</b> (b)system number as <b>00</b> (c)Client number as <b>100</b> (d)Language as <b>en</b> (e)user as <b>ABCD</b> (f)password as <b>1234</b>
I haven't choosed the check boxes <b> Local bundle </b> and <b> Unicode </b> and pressed the set button. So like this i created the RFC destinations. under the <b>properties</b> tab there is a property called <b>RFC_DEFAULT_DESTINATION</b> by default it was false so i made it as <b>true.</b> .
I also went to <b>SLD Data Supplier</b>,under <b>Runtime</b> 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 <b> sm59 </b> transaction. There under TCP/IP connections i been to <b> SLD_NUC </b>, opened this by double clicking that and under Technical settings for <b> Program ID </b> I had given the ID which I created at visual administrator [JCO RFC Provider] which is <b>mySLD </b>, under gateway options for Gateway Host as <b>10.10.10.125</b>and Gateway service as <b> sapgw00 </b> 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 <b>sapmsUV0 3600/tcp </b> entry at
<b>WINDOWS\system32\drivers\etc</b>\services file, and also there are some required entries which are already existing those are <b>sapgw00</b> <b>3300/tcp</b> to <b>sapgw99</b> <b>3399/tcp</b> , another entry starts from <b>sapdp00s</b> <b>4700/tcp</b> to <b>sapdp99s</b> <b>4799/tcp</b> , next entry starts from <b>sapgw00s</b> <b>4800/tcp</b> to <b>sapgw99s 4899/tcp</b> and <b>sapmsJ2E 3601/tcp </b> .
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 <b> Name </b>: COMPANY_CODE_RFC_METADATA
<b> Client </b> : 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
<b>Dictionary Meta Data</b> and <b>application Data </b>
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$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=v011 GROUP=DEFAULT R3NAME=UV0 MSSERV=sapmsUV0 PCS=1 ERROR service 'sapmsUVO' unknown TIME Fri Jul 01 07:20:41 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1
second time
com.sap.mw.jco.JCO$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 '?' unknown TIME Fri Jul 01 07:20:41 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1

Problem in creating JCO connection
Hi All,
I am using ECC 6.0.While creating the JCO connection in available products ECC 6.0 is not available.I am getting ECC 5.0 . Can I use ECC 5.0 or else what I need to do to get ECC 6.0
Please reply soon
Regards
PawanHi Pawan,
The others here are correct. You can either update the SLD server with the latest CIM content and then you will have the ECC6 sytem to connect to or you may wish to simply select the ECC5 option.
This configuration is really only a description for your landscape and while it is ideal that this is accurate it wont actualy hurt you to use another ECC version.

Problem testing Metadata in JCO connections (Flightlist)
Hello:
I have the sneak preview WAS Server Java 6.4 (J2EE) and I have also installed the MINIWAS 6.2. I have successfully setup the SLD and imported the 2 zip files. I can start SAP, and through SM59 test connect to SLD_NUC. I can use RZ70 to 'send' info. I can successfully load, build, archieve the Flightlist demo. I can go to http://localhost:50000/Webdynepro/welcome... and create and test the Model data under JCO connections (not using load balancing). When I test 'metadata_dest' I get the RFC_error_communication Group Public not found. I tried your fix (services file sapmsBSP 3200 from another post), but this makes it not possible to connect to sap since I think SAP listens on port 3200. Any thoughts? Can I spoof my single server system to think its has load balancing?
Thanks
Russ Wagner
CanadaHi,
If in SMLG menu "goto->load distribution" the field "current logon instance" is empty run report RSRZLLG0_ACTUAL without the flag FRCE_SAV...
After the run the field should be the name of your instance...
check with:
lgtst -H pc -S sapmsnsp -D 1
the output should be:
list of reachable application servers
[pc_NSP_00] [pc] [192.168.1.6] [sapdp00] [3200] [DIA UPD ENQ BTC SPO ICM ]
list of selectable logon groups with favorites

JCO connection pool is exhausted
hi
I am using RFC module in my web dynpro application. When the application is used for sometime, the JCO connection will get exhusted. The JCO connection will not release itself. I can't find any method in web dynpro to release the connection manually. How can I solve this problem?Hi,
What is scope of the connection. View properties of MODELDATA and METADATA destinations.
You can change the scope of the connection..
or
wdContext.current<BAPI INPUT>Element().modelObject().modelInstance().disconnectIfAlive();
For more ways , give a forum search.. There are a lot of close forum posts.. Gud luc..

How to use a JCO connection pool in an EJB?
Hi *,
I want to build a WebService using SAP Web AS (J2EE Engine) that connects to a R/3 ERP (release 4.7).
I thought of building a stateless session bean that will be deployed as webservice. The session bean shall connect to the R/3 in order to call some BAPIs. I'd like to use a JCO connection pool. But I'm not sure, where I should create and destroy the connection pool. Are the EJB methods ejbCreate() and ejbRemove() the right ones? If so, my businness methods would just have to get a connection from the pool and call the BAPIs, right? If not, what do you suggest?
Another question: I already deployed a bean as webservice. Since not really knowing how to use the connection pool, I created a bean with one business method that creates a connection pool whenever it gets called. But if I have to change something in the bean so that I have to redeploy the bean I can't call my business method anymore, because JCO cannot load a native library once again, as it is already loaded, This leads to an exception. So I have to restart the complete engine everytime I redeploy my bean. Are there any workarounds for this problem? I'm not sure whether this is connected to the wrong use of the JCO connection pool.
Kind regards,

Message was edited by: Hannes DeflooHi
Please configure your SLD. Your SLD holds the system definition. Define a SAP WebAS abap system and then try to create a Metadata connection using WebDynpro content administrator. Now you will be able to see the msg server defined in the dropdown. Also ensure that you have the message server entry in your services file.
Refer these links for SLD

Thanking.
RajendraHello 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'.
Regards,
Prathamesh. -

please give some pointers like what needs to be done JCO settings in Backend.
Thanks in advance.Niranjan,
3 causes and many more....
First and most probable cause is that your CR content in SLD is old....
FIX - to fix this download latest cimsap and crcontent from service.sap.com and implement in SLD.
Second cause user is locked
FIX - unlock in R/3
Third cause could be that the connection pool in JCO is exhausted.
FIX - increase connection pool in JCO.
More causes.
With this new version it appears that any error before connection is created ends up showing this, so I would really go into default trace and look there for original errors, that is the way I found JCO pool was exhausted, that error was not being forwarded and instead it was showing this error...
reward points if helpful
