JCO Exception(102)

hi folks,

when fetching data from an rfc func.mod from r/3 i get an exception:

JCO Exception(102) JCO_ERROR_COMMUNICATION no protocol: 01

does anyone has an idea what went wrong?

how to find easily answers to such errors?

one side-question:

i want to debug a webdynpro application, but the IDE says Server is not in DEBUG-Mode! Any Ideas where to customize that entry?

kind regards

    To Debug,

    You could activate the debugging from the NDS or by changing the server config file. Ideal way is to start the debugging from NDS using the J2EE engine view.


    1.Right Click on the server0 and choose "Enable Debugging of Process"
