JCO Destination error

[Former Member]

Hello All,

I have created a Web Dynpro project and deployed it successfully. Now while trying to create a Jco Destination in Content Admin -> WebDynpro, I get the following error. Any ideas ?

We have EP 6 with SP 9 and backend is 46c

Hi Swami,

First you need to configure the Jco Connection in the webdynpro content administrator.

Again for doing this you need to configure the SLD.You can do this using the J2EE visual Administrator.

Hi Swami,

http://<your server>:<port>/index.html

click on webdynpro ->Contentadministrator->

you will be directed to following URL

http://<your server>:<port>/webdynpro/dispatcher/sap.com/tc_wdtools/Explorer

Here you check the SLD Connection and JCO destinations once you configure this (all the five steps are through)give correct client name ..

deploy once again your dynpro application.

hope this helped you

for any other details let me know

Regards

Hi Swami,

as far as I understand, you are getting this error at the time of creating the JCo destinations in the WD Content Administrator. Will you please check your sld connection first, by going to http://host:port/sld, u must have created one sld entry there which directs to the r/3 system. So please test it's connectivity. Please check whether each entry in Visual Admin --> SLD Data supplier is correct or not - here u have to provide connection data about the sld in HTTP settings and CIM Client settings tab. Then while creating the JCo destinations be sure to select correct desitnation types (application & metadata) while creating, correct client id and system id.

From the exception it seems that its coming due to some wrong system information. Thats why these checking I am suggesting to you.
