Org.hibernate.InvalidMappingException: Failed to parse the display of the document from * .hbm.xml

I know that many people ask this question, but I read almost everything, but not one of them helped me. I am writing an eclipse maven project with hibernate and I get this error:

org.hibernate.InvalidMappingException: Could not parse mapping document from resource ir/ac/ut/ieproj/da/Student.hbm.xml

my files look like this:

DepartmentRepo.java

I think the problem is with the many-to-one tag in Student.hbm.xml, because Department.hbm.xml and namedQuery do not cause errors inside. What am I doing wrong? I use the mvn package to create the .war file and then deploy it to tomcat 7.

The error Could not parse mapping document is due to the fact that your xml files are not correctly formed. When this error occurs, we better check our xml files to make sure they are in order (all tags are closed correctly, etc.).

In your case, as the message says, your Student.hbm.xml file is the problem. You have tags that do not belong:

 <property name="firstName" type="string" column="FirstName" /> </property> <------------------------------------------------------ remove this <property name="lastName" type="string" column="LastName"/> </property> <------------------------------------------------------ remove this <property name="program" type="string" column="Program"/> </property> <------------------------------------------------------ remove this

Those closing tags </property> do not close anyone, since the <property tags above them are self-closing (pay attention to /> ).

Try changing the display of the DTD sleep mode. My problem is solved after changing http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd to http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd

This problem may be due to a mismatch of the variable names used in the bean class.

For example, then your variable names should be FirstName.

In my case, it was just a comment at the beginning of xml. If anyone has a comment, just delete it and maybe it will work.

Remove <?xml version="1.0"?> From your mapping and configuration file. He will solve your problem.

you could set up a matching tag several times for the same object / persistence.

My problem is solved after changing http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd to http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd . The problem may be caused by a timeout while accessing the remote DTD file.

I would download hibernate-mapping-3.0.dtd and make it available locally.

You just close your property, for example

 <property name="firstName" type="string" column="FirstName" />

or

 <property name="firstName" type="string" column="FirstName"></property>
