05:25 mr_lou Morning!
07:13 noreason joined ##friendlyjava
07:13 noreason my question is when i change jsp i dont need to restart but on change of servlet need to restart , how to change the default configuration for tomcat ?
07:13 noreason aditsu
07:14 noreason pdurbin
07:16 aditsu noreason: I think you can only achieve that by running the server in debug mode and doing hot code swapping; an IDE such as eclipse can help with that
07:18 aditsu I usually run jetty (embedded) in debug mode during development, and many code changes are reflected immediately
07:19 noreason aditsu what about on production
07:19 noreason i struggled like more than 10 times when my client asked for changes
07:19 aditsu in production I need to redeploy
07:19 noreason why
07:20 noreason why we cant do hot code swappin
07:20 aditsu I suppose you could do it if you run it in debug mode, I never tried
07:20 aditsu but some changes require restarting the application anyway
07:21 noreason since jsp turn to java file (servlet) than .class file
07:21 aditsu also, if you keep fiddling with the application in production, you're likely to cause a lot of problems; better to change it locally, test then deploy
07:21 noreason i want same thing to happen for servlet in production
07:22 noreason i mean IT!
07:23 * noreason aditsu why this question is not answered correctly in SO :/
07:23 aditsu I don't know, I don't control SO :p
07:24 aditsu I don't even know if it's answered
07:28 noreason why they give timestamp for jsp and avoid it for servlet ?
07:28 noreason any clue aditsu ?
07:29 aditsu what timestamp?
07:29 noreason jsp change detected by classloader
07:32 mr_lou joined ##friendlyjava
07:32 aditsu well, jsp's are designed to be compiled at runtime
07:33 * noreason hi mr_lou
07:33 noreason thats weird
07:35 aditsu it's just like being interpreted, except there's an extra compilation step
07:45 noreason <tomcat channel>they have said to turnoff jsp changes checker since it checks when you request every time
07:45 noreason http://tomcat.apache.org/tomcat-7.0-doc/jasper-howto.html
07:46 noreason they said same thing in SO :|
