Jasper with Hibernate - entity class not found

Question

I am trying to create a jasper with a sleeping compound, as shown in the tutorial http://www.tutorialcenters.com/index.php/how-to-design-report-using-jasperreport-hibernate-connection/

I did exactly as instructed, but when I get entity class not found: mappings.EmployeeMaster

Can someone tell me some solution for this ....

Answer 1

You specify Jasper in the source files. Jasper wants to create a jar or class files. Create your project in Netbeans and see the output for the location of the bank.

Typically, Netbeans build a jar in the dist project directory (samplehiber / dist / samplehiber.jar). This is what you need to impose on the Jasper class path.

If you want to use class files, specify Jasper in the samplehiber / build / classes directory.

Answer 2

Your class path should have EmployeeMaster.class . Make sure you rebuild the project. See where your tool creates your .class files and adds a directory to your class path.

Answer 3

I tried a similar approach to what you have done in the past. It turns out that for some reason hibernate cannot see its own XML files inside packages.

If you just tried moving EmployeeMaster.hbm.xml to the root folder of your source? those. \ src or. \ src \ java (not quite sure what netbeans has)

It worked for me. But note that my problem occurred in eclipse so that it may or may not apply to this problem. However, it's worth it. "If all else fails, keep the setting simple." This is what I always say to eliminate other factors. :)
