deployment - No web.xml in Eclipse + Glassfish v3? -

-

i created simple "hello world" servlet in eclipse (helios) + glassfish v3. using glassfish's plugin eclipse seems there no web.xml sun-web.xml in web-inf/ folder. first time glassfish bit surprised @ absence of web.xml - here of problems:

  1. where check url-mappings servlet? on creating new servlet in eclipse asks me url-mapping i'm unable find anywhere in .xml file can tweak settings.
  2. if there isn't web.xml, creating scratch quite error prone. suggest? google sample , play around? shouldn't 1 auto-created?
  3. has encountered this? tried looking difference between web.xml , sun-web.xml results weren't @ enlightening. wouldn't want learn xml configuration purposes , glassfish specific.

we have configure servlet contexts, mappings etc during development/testing sheer absence of web.xml has me stumped.

eclipse allows not create web.xml file when create dynamic web project java ee 6, since java ee 6 spec (in general) , servlet 3.0 spec (in particular) attempt de-emphasize deployment descriptors.

you can use annotation provide data had been included in web.xml file. javadoc servlet 3.0 annotations pretty obtuse. should read through servlet 3.0 spec jcp.org site bit more explanatory text.

to change url-mapping servlet 3.0 servlet, first place in source code servlet. (and change) value of urlpatterns element.

if trying create web app based on servlet 3.0, try avoid creating web.xml file.

the sun-web.xml/glassfish-web.xml file used 'finish' description of war file deployment glassfish container.

one other note annotations webservlet... not integrate annotated class class hierarchy, correct use of @webservlet like

@webservlet(     name = "myservlet",      urlpatterns = {"/path_to_servlet"} ) public class myservlet extends httpservlet {}

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
