Spring and MongoDB: SAXParseException while reading Bean Definitions

I am using MongoDB with Spring and Apache Shiro for session management. Since I came across the same issue that was mentioned in this , I resorted to using MongoTemplate directly, and not to the MongoRepository extension to implement the Realm class required by Shiro. This area is just a DAO that deals with MongoDB to save the user and role.

Right now I have a strange problem with the XML Bean Definition. It throws a SAXParserException, and I cannot understand why.

I have provided some information below. could you help me?

web.xml:

<web-app version="3.0" 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_3_0.xsd" metadata-complete="false"> <display-name>Test Web App</display-name> </web-app>

Thanks so much for your time.

The error message says it all:

Line 49 in an XML document from a class path resource [persistence.xml] is invalid; The original exception is org.xml.sax.SAXParseException: the value of the class attribute associated with the element type "null" must not contain a '<' character

Here is line 48:

 <bean id="mongoRealm" class="com.test.webapp.login.MongoRealm/> Missing double quote here--^
