XML : cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element

I do see org.xml.sax.SAXParseException in my project, but I cannot tell why it occurs.

Error Message is like following:

  SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener  org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 17 in XML document from ServletContext resource [/conf/appcontext-datasource.xml] is invalid;

Then this is the appcontext-datasource.xml that causes this problem

  <?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:jee="http://www.springframework.org/schema/jee"  xmlns:util="http://www.springframework.org/schema/util"  xsi:schemaLocation="      http://www.springframework.org/schema/jee       http://www.springframework.org/schema/jee/spring-jee-3.2.xsd      http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-3.2.xsd              http://www.springframework.org/schema/util       http://www.springframework.org/schema/util/spring-util-3.2.xsd">    <jee:jndi-lookup id="dataSource" jndi-name="jdbc/iasDB" expected-type="javax.sql.DataSource" />    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">      <property name="dataSource" ref="dataSource"/>  </bean>    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">      <property name="dataSource" ref="dataSource" />      <property name="configLocation" value="/conf/sql/alias-context.xml"></property>  </bean>    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">      <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />      <property name="basePackage" value="com.example.ias.dao" />  </bean>    

As you can see, I specified the schema location of jee, but all it could say is no declaration can be found.

FYI, this project worked perfectly fine until yesterday when I had decided to clean tomcat server for no reason.

Thank you for your help
