Data not persisting, when it is sent through service layer

Dear dudes,
I'm having a simple struts application which has a form to get username and password from the user and call the action class, which persist the data in MYSQL database
Actually in my actin class only i'm persisting the database by calling the service class, which reads the hibernate configuration file(hibernate-cfg.xml) and its mapping file
Actually, i'm getting my data and setting my data in my DAO object( i.e. logindata object in my application)
I'm having problem in persisting that DAO object into database.
My service layer is not able to read my DAO hibernate configuration from hibernate-cfg.xml

The exception i'm getting is:



My application structure:



My hibernate-cfg.xml:


Logindata.hbm.xml:


I've configured my workspace to tomcat by setting a configuration file in conf\cataline\localhost folder of Tomcat5.5

This is my action servlet:loginAction .java


My service classes:
loginservice.java


connectionfactory.java:

Here data entered by the user is getting till the action class and data is getting saved in logindata object i.e. my dao object, for which i'm sure as i generate messages which i get in my console ,but when this object is sent into service layer it is throwing mapping exception

Once again the the exception it is throwing is :


Is my application structure is right and what could be done to fix this?

Awaiting for the response!

regards.

Your mapping file appears to belong to the package com.srit.login, but it looks like you've put it at the root of the classes directory. Hibernate just looks up resources in the same way Java looks up any resource, so it needs to be in WEB-INF/classes/com/srit/login/ to be found.

Even after putting my Logindata.hbm.xml in WEB-INF/classes/com/srit/login/Logindata.xml
my hibernate configuration file hibernate.cfg.xml is not able to read the corresponding mapping file Logindata.hbm.xml

The exception trace is:


Could any one fix it.
My hibernate.cfg.xml is inside WEB-INF\classes folder.
Logindata.hbm.xml is inside WEB-INF\classes\com\srit\login folder.

Namma,

In your hibernate config file, you indicate you've listed the mapping file location as:



As Paul was saying, this tells hibnerate to try to find it in the root directory. Since you have it in the same directory as the class file, you need to update the resource's path:
