I create a generic DataAccessObject and try to save a data in my database

HibernateDAO.java


I use JSF and Hibernate in my application.

This code works perfect when i call him inside netbeans like a desktop app



but when i try to use him inside a JSF app, he give me a error



this is the ManagedBean that i use to save data through xhtml file

GravaCidade.java


why this don't work in JSF app?

So your error message is "java.lang.NoClassDefFoundError: br/salesianos/dao/HibernateDAO"
It works for your stand-alone application, but not for your web application.

Have you added this class into the classpath for your web application?
Classpath for a web application means the WEB-INF/classes folder and jar files in the WEB-INF/lib folder.

I think the only thing you are missing is to tell NetBeans that your web application wants to use this code.
I don't know much about Netbeans, but presume you already have a "web" project that runs a web server through netbeans? Or are you deploying externally somewhere?
 
I agree. Here's the link: http://aspose.com/file-tools
