Understand the purpose of the various external libraries you need to install into Unwired Platform to enable communication with an SAP EIS.
- SAP Java Connector (JCo) – required for both Unwired WorkSpace and Unwired Server where connections to an SAP EIS are required. This is not required if you are accessing SAP through a Web service.
- SAP Cryptographic Libraries – required by Unwired Platform to enable Secure Network Communications (SNC) between Unwired Server or Unwired Workspace and the SAP EIS.
- SAP SSO2 Token Libraries – optional for Unwired Server. These libraries are only required if you use single sign-on (SSO) with SSO2 tokens and want to enable persisted token caching. The default, and recommended approach, is to use the Unwired Server authentication timeout interval setting, which does not require these libraries.
- SAPCAR utility – required to extract files from certain downloaded SAP files such as the SAP cryptographic library and RFC library.
