java - Spring cvc-complex-type.2.4.a: Invalid content was found starting with element 'channel' -

i have below contexto.xml file:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"   xmlns:p="http://www.springframework.org/schema/p"   xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"   xmlns:context="http://www.springframework.org/schema/context"   xmlns:int="http://www.springframework.org/schema/integration"   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"   default-init-method="iniciar"    default-destroy-method="destruir">      <import resource="otherfile.xml"/>     <import resource="otherfile2.xml"/>   <!-- other stuff -->  <!-- spring integration channel --> <int:channel id="helloworldchannel" />  <!-- spring integration adapter routes messages sent helloworldchannel bean named "helloserviceimpl"'s hello() method --> <int:service-activator input-channel="helloworldchannel" ref="helloserviceimpl" method="hello" /> 

when editing file in eclipse, marks 'channel' error. editor says below message:

cvc-complex-type.2.4.a: invalid content found starting element 'channel'. 1 of '{"http://  www.springframework.org/schema/beans":import, "http://www.springframework.org/schema/beans":alias,   "http://www.springframework.org/schema/beans":bean, wc[##other:"http://www.springframework.org/  schema/beans"], "http://www.springframework.org/schema/beans":beans}' expected. 

anyway can build application , execute in run time below exception generated:

if replace below start line in contexto.xml file:

<beans xmlns="http://www.springframework.org/schema/beans" 

by

<beans:beans xmlns:beans="http://www.springframework.org/schema/beans" 

then 'channel' recognized , editor no longer marks error import line marked error now:

cvc-complex-type.2.4.a: invalid content found starting element 'import'. 1 of '{"http://  www.springframework.org/schema/beans":description, "http://www.springframework.org/schema/  beans":import, "http://www.springframework.org/schema/beans":alias, "http://www.springframework.org/  schema/beans":bean, wc[##other:"http://www.springframework.org/schema/beans"], "http://  www.springframework.org/schema/beans":beans}' expected. 

updated

i have added int namespace before chanel continues saying there error. anyway can build , execute app below exception thrown:

finally have added below lines xsi:schemalocation:

  http://www.springframework.org/schema/integration   http://www.springframework.org/schema/integration/spring-integration.xsd 

after adding above 2 lines, no errors marked within context.xml when execute app, exception thrown:

also have tried specify version in contexto.xml:

http://www.springframework.org/schema/integration/spring-integration.xsd 

that is:

http://www.springframework.org/schema/integration/spring-integration-1.0.xsd http://www.springframework.org/schema/integration/spring-integration-2.0.xsd 

but not working, same exception thrown in run time.

last update

some dependencies missed in maven pom.xml file. have added below dependencies:

    <dependency>         <groupid>org.springframework.integration</groupid>         <artifactid>spring-integration-core</artifactid>         <version>4.1.2.release</version>     </dependency>     <dependency>         <groupid>org.springframework.integration</groupid>         <artifactid>spring-integration-jms</artifactid>         <version>4.1.2.release</version>     </dependency> 

now works! ;)

you have use defined namespace resource using, on case:

<int:channel id="helloworldchannel" />
