I know this question has been asked a lot, but I read almost every one of them but non of them helped me. I'm writing an eclipse maven project with hibernate and I'm getting this error:
org.hibernate.InvalidMappingException: Could not parse mapping document from resource ir/ac/ut/ieproj/da/Student.hbm.xml
my files are like this:

I think the problem is with the many-to-one tag in Student.hbm.xml because Department.hbm.xml and the namedQuery within are not causing an error. What am I doing wrong? I'm using mvn package to make a .war file and then deploy it in tomcat 7.
The error Could not parse mapping document is about your xml files not being well-formed. When this error comes up, we'd better double check our xml files to see if they are really OK (all tags are properly closed and so on).
In your case, as the message states, your Student.hbm.xml file is the problem. You have some 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 </property> tags aren't closing no one, as the <property tags above them are self-closed (notice the />).
Try to change hibernate mapping DTD. My problem solves after changing http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd to http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd
May Be This problem because of Not matching with The variable names used in bean class.
For eg. Then Your variable names should be FirstName.
In my case was just a comment at the beggining of xml. If someone have a comment like just remove it and maybe will work.
Please remove <?xml version="1.0"?> from your mapping and config file.It will solve your problem
you might have configured multiple times of mapping tag for same entity/persistence.
My problem solves after changing http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd to http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd. The issue could caused by timeout when access to remote DTD file.
I would download the hibernate-mapping-3.0.dtd and make it available locally.

You just close your property like
<property name="firstName" type="string" column="FirstName" />
or
<property name="firstName" type="string" column="FirstName"></property>
