[Former Member]

Dear All,

did somebody solved the problem with JCO Exception Nr. 120? What does it mean exactly? I call a JCO Server with a function from SAP and i receive the following error:

2007-05-02 14:32:03,781 INFO [STDOUT] Exception in Server JavaServer:

The function in SAP looks like this:

FUNCTION ZES3_SERVER_SIGN.

IF sy-subrc <> 0.

ret = -1.

CONCATENATE 'application/' doc_type INTO l_docmim.

Hi Abhijeet,

thank you for your reply. I've tried your solution but it didn' t help.

I renamed the function im ABAP code to BAPI_COMPANYCODE_GETLIST, and it worked. I have to check why the code with SERVER_SIGN didn' t work.

Thank you again.

Andras,

Sorry for my earlier post, It was mistake on my part. Neglect that post.

Well the thing is , your FM name is ZES3_SERVER_SIGN and not SERVER_SIGN(this is inturn getting called from ZES3_SERVER_SIGN ), so the Dynpro wont know SERVER_SIGN. So your JCO call should be to ZES3_SERVER_SIGN, and not SERVER_SIGN.

also make sure that they are Rmote enabled

hope it helps
