JCo is a free tool provided by SAP to its customers and partners. It currently runs on Microsoft Windows NT 4.0 with Service Pack 4 or later, Windows 2000, Linux Kernel 2.2.14 or later, Sun Solaris 2.8 or later, IBM AIX 4.3 or later, HP-UX 11.0 or later, and Compaq Tru64 5.0 or later. The only way to get a copy of JCo is to be a partner or customer and have a valid ID for the SAP service site named SAPnet.
The software can be downloaded on the Internet at http://service.sap.com/connectors. This site requires a login with an active ID and password. If you work for a company that has SAP, you must apply for an OSS ID or ask someone to login and download the software for you. JCo must be the correct version for the operating system environment it will run in.
After receiving the zipped file from JCo, unzip it into a temp directory. To install on a Microsoft Windows machine, JCo needs three .dll files put in the windows/system32 directory and the jco.jar file in the classpath of your Java compiler and runtime environment of WebLogic Server. Table 32.1 shows the location for the 1.1 version of JCo.
JCo 2.0 requires Java runtime libraries 1.2 or greater. Installation is a bit different because the files have changed. The jco.jar file has been replaced with sapjco.jar. The jRFC12.dll file has been replaced with sapjcorfc.dll. The required librfc32.dll file must support the runtime library 6.20 or greater. Table 32.2 shows the location for the 2.0 installation of JCo.
If you've previously installed the 1.x version of JCo, remove the .dlls from your system because they cause conflicts with JCo 2.x.
