Hi Guys,

Im encountering this kind of problem and I read a lot of solutions but still the error exist.

Here's the problem:

java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'

JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc [C:\Program Files\IBM\WebSphere Studio\Application Developer IE\v5.1.1\eclipse\jre\bin\sapjcorfc.dll: Can't find dependent libraries]. java.library.path [C:\Program Files\IBM\WebSphere Studio\Application Developer IE\v5.1.1\eclipse\jre\bin;.;C:\WINDOWS\System32;C:\WINDOWS;C:\Program Files\IBM\WebSphere Studio\Application Developer IE\v5.1.1\eclipse\jre\bin;C:\PROGRA1\PVCS75\vm\win32\bin;C:\PROGRA1\PVCS75\vm\common\bin\win32;C:\program files\notes\;C:\data\notes\;C:\oracle\ora92\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\Support Tools\;c:\program files\winzip;c:\data\notes;c:\program files\notes]

at MaterialList.main(MaterialList.java:22)

Exception in thread "main"

I already put the files need on the proper folder but still it does'nt work.

Can anyone help me specify the right folder and the right file that should be inside that folder. I have the follwing files:

- librfc32.dll

- sapjco.jar

- sapjcorfc.dll

Also, can you give me the exact path with value in the environment variable.

Thank you very very much in advance. =)
