In this chapter, we covered most of the aspects of programming in JCo. More resources can be found inside SAPnet at http://service.sap.com. This site requires a valid customer or partner user ID.
We saw that JCo provides an easy-to-use API to connect to SAP. It has proven itself stable and production worthy. This API is proprietary, however. SAP released a J2EE-CA compatible connector early in 2003 in a beta version. This connector was covered in Chapter 31. Other companies, including BEA, have SAP connectors. Some of these companies are also already J2EE-CA compliant. The basis of all these J2EE-CA–compliant connectors is JCo. JCo will continue to be used as the backbone of SAP-Java connectivity even after J2EE-CA matures less in the Web arena and more in standalone applications.
