JCO installation 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

Hello,

> X connection to mazda:13.0 broken (explicit kill or server shutdown).

Do you have a X-Server running on "mazda"? If not try to use this Java X Server: http://www.jcraft.com/weirdx/ and redirect with the DISPLAY environment variable.

Regards
