Error Creating JCO

[Former Member]

Hi,

this topic acctually already exist but contents doesn't seem to solve the problem I have. So I'd just want to post it here again.

Like all beginners I follow the practice all the way till creating JCO connection. I got stucked on the step 3(connection type)while having default radiobutton already chosen(Message Server Connection), I click next. this error windows appears like below.

Hi,

Have you configured your SLD already?

I believed so, but how do I know if my settings are correct? Seems if I input the wrong parameters settings, the SLD server can start anyway.

Hi,

Hope you have tested the SLD connections at the content administration.

The below link would be helpful for the configuration of SLD

Thanks you, Noufal.

I follow your hint into the sld help file, figured out I still need my data supplier to set up and from then on. here's my newest problem.

I'm inside a customer's company internal network connecting the outside line thru several hops back to IDES(test system) back in my office.

so far I only have the NW Dev Studio/WAS.Java/sap frontend on my machine. as the help guided, I'm in RZ70 trying to input <Host> & <service>, but isn't <Host> pointing to my machine??? I'm not sure how my IDES can get a way thru while I only have a 192.168.1.X ip. Is there a solution or I'm just stucked here?

Looking forward for your conclusion about this,

thanks for everything again.
