Hi,

First you need to enable your check SLDconnection button in contentadmin -webdynpro.

for this you need to add the port ip and port number username and URL this should be done at the time of portal installation only otherwise consult your admin.

then only the http://<ip>:<port>/sld url will work then u can add your technical system there your are adding the R/3 system information like user name and password and version numeber and all.

Once this happend you can create the JCO names that should be got thru this link.

Thanks,

Lohi.

Hi Mukesh,

I have entered the service name in c:\windows\......\servicess.

ex: sapmsecc 3600/tcp

C:\WINDOWS\system32\drivers\etc\hosts

<IP> <alias>

means give me the example..<ip> <alias>.

Thanks in advance

Hi Akruthi Prasad,

in c:\...\..\hosts

we need to enter IP Of the system with alias.

i.e., If your sap R/3 or message server is in system123 an it's IP address is 172.168.2.10 , then you should enetr thr IP of that system in the hosts as

172.168.2.10 system123.

See in the NWDS, in window tab>preferences>sap j2ee engine, you will type the host as the system where your sneak preview is installed. then the NWDS searches in the c:\..\..\ hosts file for the ip of the host name you entered. and then communicates with the IP through the respective port number you entered in the c:\..\...services file

Hello Sai,

which IP i need to give R/3 IP or was 6.40 IP.

my R/3 IP is 172.20.70.201 systemmlbpsap01. I enter this one

in was 6.40 machine i entered serice name like SAPMSECC 3600/TCP(R/3 message server sid and port).

Thanks in advance

Hi,

this is the host u need to add the R/3 system ip and system number and portal Ip and address.

C:\WINDOWS\system32\drivers\etc

Here open the note pad u can add

For R/3 :

172.20.70.201 systemmlbpsap01

For Portal

like that some what you have

172.20.70.200 portal.

After this .

U can goto the Contentadmin and check you Jco metadata and model data if these are green then you can utilize in import model.

When impor the model u need to give correct dat I mean to say system name and client and username pwd .

Is these two options are ok then you can success your JCO.

Thanks,

Lohi.

Hello Prasad,

Can you clarify me like in which system is your R/3, Sneak preview, and from which system you are working on NWDS.

Because if your sneak preview and R/3 are in same system the sld configuration is different, and if they are in different system they are different.

How ever you need to give both the IP address in the hosts file if they are different. and only one if they are on the same system.

and one more, while creating a JCO connection, in the step 4 i.e., message server parameter entries, in the drop down do you get the R/3 system entry which you defined in the sld configuration.

Sai krishna.

Hi Lohi,

Still the same error.

[Former Member]

Hi,

ping your Jco's destinations once.

If those are in green color then only you can utilize the JCo's.

And chek your properties of your R/3 system details when you call the model from R/3 system.

it might helps you.

Thanks,

Lohi.

Hi Akruti Prasad,

Have you sort out the error. Can you please tell me how di du do that. I am also getting the same error

Thank you

Hi,

1.Check your JCO's once other wise create new jcos utilize those.

2.And when importing your Jco check your r/3 system properties properly.

3. Add your IP address in windows Host file

These are the reasons only to get this error.

Thanks,

Lohi.
