Why can't web.xml 'context-param' have the character [children]?

I'm just wondering what will happen with this web.xml code, where I have this cvc-complex-type.2.3: Element 'context-param' cannot have character [children], because the type content type is element-only. in the Eclipse (juno version) Markers view.

Here is the code:

 <?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name>Spring security web application (series)</display-name> <!-- to specifically stop trouble with multiple apps on tomcat --> <context-param>  <param-name>webAppRootKey</param-name>  <param-value>customauth_root</param-value> </context-param> <!-- Location of the XML file that defines the root application context  applied by ContextLoaderListener. --> <context-param>  <param-name>contextConfigLocation</param-name>  <param-value>  WEB-INF/applicationContext.xml  WEB-INF/applicationContext-security.xml </param-value> </context-param> <!-- Loads the root application context of this web app at startup.

First, you use illegal characters inside your XML node param-value

You are not allowed to use "/", "<", and other characters inside the node, since it will break the parsing of the XML document.

You should use CDATA or PCDATA covers around your value inside the XML node.

eg.

  <param-value><![CDATA[  WEB-INF/applicationContext.xml  WEB-INF/applicationContext-security.xml]]> </param-value>

That was the cause of your problem.

Some invisible characters are not considered an XML space, so an error is displayed. Display all the space characters by customizing the Eclipse Text Editor preferences, then rogue characters will stand out. You can also use this tool to validate your XML file:

 xmllint --noout --schema http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd XML_FILE

You comment on the closing tag, see <filter-mapping> again:

  <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern> /*</url-pattern> </filter-mapping>`
