In general terms, which are the most important restrictions when using the Java Connector for SAP and Java RFCs for SAP?
One major concern when using JCo is simply that of SAP system resources. The SAP application server has a limited number of dialog users that can be allocated for use across the enterprise. Because JCO uses a synchronous RFC call to connect to SAP, it consumes a work process. If these connections are not carefully managed, you could wind up eating up every available work process, depending on the level of traffic your application gets. See my tip on connection pooling with JCo at SearchSAP.com.
