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 :


Failed to create new JCO client connection WD_FLIGHTLIST_RFC_METADATA_DEST: Error while obtaining JCO connection.

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 !
