Transports and Interfaces: Siebel Enterprise Application Integration > EAI Java Business Service >
Restrictions for Implementing JBS
When implementing a Java business service, keep in mind the following recommendations and restrictions:
- You cannot use 64-bit JVMs with Java business services in Siebel Business Applications, which are 32-bit.
- Each business service method invocation is atomic and stateless.
- The explicit creation of threads is discouraged. It is not recommended that customers invoke a multithreaded component from a Java business service.
- All data and context required to perform the necessary business functions must be provided as input to the class. The external Java class cannot call back into the Siebel application to obtain additional context.
