Hi,

open \windows\system32\drivers\ect\services in notepad and add <b>sapgw00 3300/tcp</b> in your system from where you are trying.

Helloo Ajay ,

u better try to use sapjco.jar and the associated dll's which are specific. i had this problem , but through my experience , i could realize that for a particular sapjco.jar specific dll's are present . if u get this entire thing as a pack (sapjco.jar and associated dll's ) i think it will work . really i have faced the same problem and i could resolve this problem in that way..

that dll's are installed along with the sap GUI.

You do not need to have the librfc32.dll in the system32 folder.

Here is what you need.

sapjco.jar

librfc32.dll

sapjcorfc.dll

+ depending on the version the 4 .net dlls needed (see sapnote with jco version 2.1.5)

ALL in the same directory (\sap\jco)

Have that directory on your path

Have sapjco.jar on your classpath

This should do it.
