2- web.xml:

<web-app>   <display-name>checkout</display-name>    <servlet>     <servlet-name>checkout</servlet-name>     <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>     <load-on-startup>1</load-on-startup>   </servlet>    <servlet-mapping>     <servlet-name>checkout</servlet-name>     <url-pattern>*.action</url-pattern>   </servlet-mapping>  </web-app>

3- checkout-servlet.xml:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:context="http://www.springframework.org/schema/context"     xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">      <context:component-scan base-package="com.myapp"/>      <bean id="myservice" class="com.myapp.myservice"/>  </beans>

also when trying access page in application, exception:

http status 404 - servlet checkout not available  type status report  message servlet checkout not available  description requested resource (servlet checkout not available) not available. apache tomcat/7.0.22

you need add "maven dependency" in deployment assembly

  • right click on project , choose properties.
  • click on deployment assembly.
  • click add
  • click on "java build path entries"
  • select maven dependencies"
  • click finish.

rebuild , deploy again

note: applicable non maven project.

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
