JCO related error

[Former Member]

hi ,

We are trying to run a application which uses swings as frontend and SAP R/3 system as a backend. The connection to R/3 is done by a JCO program written in java.

If the application is excecuted in a system where NDS is already installed it works fine.But it throws an error if there is no NDS installed in it.

The error while running the java appication is :

This error is shown in the alert box :

-

---

java.exe - Entry Point Not Found

-

---

The procedure entry point RfcDsrInit could not be located in the dynamic link library LIBRFC32.dll.

-

---

OK

-

and then when we say ok the following happens

Exception in thread "main" java.lang.ExceptionInInitializerError: JCO.classIniti

alize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'

JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc [no sapjco

Can anyone suggest me where the problem is and how to rectify it.

Put the librfc32.dll and sapjcorfc.dll in windows/system32 directory.

Hi,

this problem was discussed a lot in the forums. This error happens because the system cannot find the Jco libraries. Have a look at this to find out to solve the problem (steps 2 and 3 especially!)
