i have a game - applet which includs a highscore. to save the scores permanently theres also a servlet for accessing the server resources. so if theres a new highscore reached the applet sends it to ther servlet, which writes the score in a txt-file on the server. but im smelling problems if several applets are running at the same time: for each applet instance a unique servlet connection is created for highscore entry. so only **** would happen if one connection writes to the file, another one reads at the same time and so on.
how can i safely synchronize the data ?
btw: for this project i have no access to a database (which would make many problems obsolete ...)
as far as i know every applet which starts an urlconnection results in a new instance of the servlet. so i have to care about more than one servlet instance. to have a shared copy of the highscore in memory i would declare it only as static and declare the methods which access the highscore as synchronized...
did i get the point right ?
