Error in connecting to SLD

Hi All,

I am trying to create the Jco destinations as part of the ESS and MSS configurations.But, when i login to http://hsotname:port/webdynpro/resources/sap.com/tc~wd~tools~admin/Explorer i am getting the below error.

I have checked SLD status in http://hostname:5XXXXX/webdynpro/resources/sap.com/tc~sld~wd~main/Main , their its showing "SLD running".

We are using Portal version 7.4.

Can anyone tell me what's the problem.

Regards,

Anil
