Hi Everyone,
I am BASIS admin and was trying to understand the basics of SAP Web AS Java, so was going thru the online help, after reading some documents was bit confused.
http://help.sap.com/saphelp_nw04s/helpdata/en/2e/611724f410254ca12a3f396ec5ae85/content.htm
This link above provides very clear view of the Java architecture. I proceeded a head to read the internal architecture of Dispatcher as well as Server process, but the link pasted below which states the internal architecture of J2EE pushed me to a confused state.
http://help.sap.com/saphelp_nw04s/helpdata/en/51/c01bc857c29f43ade7082e6a8dce07/content.htm.
This link states that the J2EE Engine System Architecture has 3 logical layers
1) Java Enterprise Runtime
2)J2EE Engine Components
3)Application.
I was unable to corelate the 3 logical layers described above to the physical components of the Java Engine as I could see that both Dispatcher & Server processes have the Managers,Services, Interfaces and Libraries.
Request you to clear my doubt. I was cross checking this theory to our Web Dynpro development system running on WAS Java SP20.
Thanks in advance.
