    <p>I am using NetbeansIDE 7.2. and pgAdmin III PostgreSQL 9.2 with Database name "StudentReports".</p> <p>I know a little of Hibernate and generating JasperReports using native SQL through JDBC Connection, but I am new to generating JasperReports connecting thru Hibernate Connection which this tutorial shows.</p> <p>I am getting o<code>rg.hibernate.InvalidMappingException: Unable to read XML Error</code> and <em>never</em> made a successful Hibernate Connection test, an error pops up saying "Could not parse mapping document from resource com/report/mappings/Department.hbm.xml", after following this tutorial <a href="http://bhaskaravignesh-j2ee.blogspot.com/2010/07/jasperreports-with-hibernate.html" rel="nofollow">"JasperReports with Hibernate - Module 1"</a> and <a href="http://bhaskaravignesh-j2ee.blogspot.com/2010/07/jasperreports-with-hibernate-module-2.html" rel="nofollow">JasperReports with Hibernate - Module 2</a>. It has 2 Modules. But I did a little modifications on its data access object (DAO) files and I just wanted to have a Department Records. Also, I used a different version of Hibernate and Jasper Reports Package and iReport Plugin for Netbeans which are Hibernate Release 4.1.9 and Jasper Reports 5.0.1 and iReport-4.5.0. I have added all of the jar files of it to my project's Library.</p> <p>This is my first time handling hibernate mapping xml files and data access object files.</p> <blockquote> <p>log4j:WARN No appenders could be found for logger (org.jboss.logging). log4j:WARN Please initialize the log4j system properly.<br> Exception in thread "main" org.hibernate.InvalidMappingException: Unable to read XML at org.hibernate.internal.util.xml.MappingReader.readMappingDocument(MappingReader.java:109) at org.hibernate.cfg.Configuration.add(Configuration.java:478) at org.hibernate.cfg.Configuration.add(Configuration.java:474) at org.hibernate.cfg.Configuration.add(Configuration.java:647) at org.hibernate.cfg.Configuration.addResource(Configuration.java:730) at org.hibernate.cfg.Configuration.parseMappingElement(Configuration.java:2115) at org.hibernate.cfg.Configuration.parseSessionFactory(Configuration.java:2087) at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:2067) at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:2020) at org.hibernate.cfg.Configuration.configure(Configuration.java:1935) at org.hibernate.cfg.Configuration.configure(Configuration.java:1914) at com.report.dao.DepartmentDAO.saveDepartment(DepartmentDAO.java:20) at com.report.test.AddDepartments.main(AddDepartments.java:20) Caused by: org.dom4j.DocumentException: Error on line 15 of document : The element type "hibernate-mapping" must be terminated by the matching end-tag "".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
