is there tutorial out there or have pointers on how following spring-security? task: i need salt database authenticating username , use encrypt provided password (from login page) compare stored encrypted password (a.k.a. authenticate user). additional information: i use custom database structure. userdetails object created via custom userdetailsservice in turn uses custom daoprovider information database. my security.xml file far: <authentication-manager> <authentication-provider user-service-ref="userdetailsservice"> </authentication-provider> </authentication-manager> now guess i'll need <password-encoder hash="sha" /> but else? how tell spring security use databaseprovided salt in order encode password? edit : i found this so post informatative not sufficient: if define salt source in xml used password encoder, so: <password-encoder ref="passwordencoder"> ...

i'm designing communication protocol used communicate between 2 pc applications using socket connection. common case when both application work on same machine, possible run 1 application on remote machine. application can exchange data 2mb/s. question is: shall use confirmation packets ensure packet sent 1 application received other one? know socket uses tcp connection confirmation/retransmission implemented need feedback used in practice. the technologies used: - socket server: .net application uses following library: http://www.codeproject.com/kb/ip/asyncsocketserverandclien.aspx - socket client: .net or delphi application this fine, traffic short-circuited in tcp/ip driver stack. there no great difference other ipc mechanism, takes memory-to-memory copy operates @ bus speeds. 5 gigabytes/sec typ microsecond or overhead. plus whatever context switching needs happen, far largest cost. named pipe operate same. falls off cliff of course once need go through ni...

let's have table taba columns: col1 - primary key (but not identity) col2 - foreign key col3 - unique constraint col4 - check constraint col5 - not null constraint also, taba has 2 triggers: instead of insert - 1 cancel insert taba (of course), in it's own code insert new row taba . values column in new row guaranteed correct after insert - 1 print string now, ready insert new row taba (insert taba values(...)). obviously, have expect events: value col1 must checked uniqueness , not null(primary key) value col2 must checked conformity parental table(foreign key) value col3 must checked uniqueness value col4 must checked against check constraint value col5 must checked not null instead of trigger must executed after trigger must executed what want reorder list(1-7) number 1 on event happen first, 2=event happen second, ..., , 7 last event. also, if event x produce error (col5=null, example) - mean events x+1,x+2.. not happen? thanks hel...
