Error while Configuring JCO on Solaris

[Former Member]

Hi all,

I configured JCO according to installation instructions in the documentation shiped with installation bundle, classpath and LD_LIBRARY_PATH variables are set correctly and I can echo and varify the paths. But whenever I access any class of JCO from JSP or run sapjco.jar from its folder, it throws an exception and restarts the server. I would highly appreciate any hint.

Here is error message with -stdout option:

mazda:dv1adm 44% java -jar sapjco.jar

Try to add the directory path where libsapjcorfc.so file resides in LD_LIBRARY_PATH environment variable and run the program.

Somthing similar is happening to me as well... I found <a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/bc-jas/~form/handler">note 542175</a> sounds interesting, but I'm still trying to figure out how to apply to my tricky scenario (MDM!)

Hello Moin,

This error might be caused by the different bitlength of your JDK and JCO library. If you use 32bit Jdk you should download 32bit JCO.

Kind Regards
