While I was working on a Spring application, I saw the following error after deploying:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 1 in XML document from ServletContext resource [/WEB-INF/BCC-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException: White spaces are required between publicId and systemId.

Here are the first few lines of the xml file the stack trace was referring to:

<?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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/jee
    http://www.springframework.org/schema/jee/spring-jee-2.0.xsd
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

The report stateed the error was in Line 1, which was obviously not the case. The problem was the order of the schemaLocation values was incorrect. Here is the correct order:

<?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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    http://www.springframework.org/schema/jee
    http://www.springframework.org/schema/jee/spring-jee-2.0.xsd">
