JCO Connectoin Error

Hello Experts,

We are using SUP 2.0 on windows 7 64 bit machine.

We have sapjco 2.1.10 (32 bit & 64 bit). We successfully connected with SAP Server through Sybase Workspace.

We copied files in proper location like,

Librfc32.dll

u2022 C:\windows\system32

u2022 Sybase\unwiredplatform\serves\unwiredserver\lib

u2022 Sybase\unwiredplatform\jdk1.6.0_24\bin (librfc32.dll must be 32bit file)

u2022 Sybase\unwiredplatform\jdk1.6.0_24-x64\bin (If system is 64bit & librfc32.dll must 64bit file)

Sapjcorfc.dll

u2022 C:\windows\system32

u2022 Sybase\unwiredplatform\serves\unwiredserver\lib

u2022 Sybase\unwiredplatform\jdk1.6.0_24\bin (librfc32.dll must be 32bit file)

u2022 Sybase\unwiredplatform\jdk1.6.0_24-x64\bin (If system is 64bit & librfc32.dll must 64bit file)

Sapjco.jar

u2022 Sybase\unwiredplatform\serves\unwiredserver\lib\3rdparty

u2022 Sybase\UnwiredPlatform\Unwired_WorkSpace\Eclipse\sybase_workspace\mobile\eclipse\plugins\com.sybase.uep.com.sap.mw.jco_<Version>\lib

But when we trying to synchronized an application it generate two errors like ,

1. Could not initialize class com.sap.mw.jco.JCO

2. c:\sybase\unwiredplatform\server\unwiredserver\lib\sapjcorfc.dll Can't load IA-64 bit dll on a AMD 64 bit.

We have intel pentium dual processor.

Please reply us.

Regards,

Tapan

    Those two errors found in Sybase Control Center's Client log for perticular package.
