How is SPECjEnterprise2010 different from SPECjAppServer2004?
A4: SPECjAppServer2004 was a J2EE 1.3 application and used a web layer and EJBs for the clients interactions with the server. In the SPECjEnterprise2010 benchmark, the load drivers access the application through a web layer (for the dealer domain) and through EJBs and Web Services (for the manufacturing domain) to stress more of the capabilities of the Java EE application servers. In addition, SPECjEnterprise2010 adds more extensive use of the JMS and MDB infrastructure.
