Which SAP JCo Release Library to use

[Former Member]

Hi all,

I need to use the below libraries in my application,

librfccm.so , libsapjcorfc.so , sapjco.jar.

I tried many , but getting exception like

" JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC' JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc "

Please suggest me which version of SAPJCo should I need to use for the below System configuration

Machine: Dell Computer Corporation PowerEdge 2850

Processor: Intel Xeon 64-bit amd64 kernel modules

OS: SunOS 5.10

OS Platform: x86

Java Version: 1.5.0_12 (49.0)

Java Vendor: Sun Micro systems Inc.

Hi,

From the installation document, Below libraries could suit my requirement,

sapjco-sunx86_64-2.1.8.tgz for a 64-bit JRE running on a 64-bit AMD or INTEL x86 processor

But i have 32 bit JRE installed in my server,

so it will work with 32 bit JRE or should i need to upgrade it to 64 bit JRE.

Kindly advice,

I think you must set the installation system libraries

check the readme file which is in the installation package
