Hi,

try the following:

write only your package path into the hibernate.cfg.xml.

That's what I mean:


<mapping resource="InsertBean.hbm.xml"/>

You don't need to write the whole path, only the package structure, but with a / instead of a point.

For example, your package structure is com.myApp.beans.InsertBean, then you have to write <mapping resource="com/myApp/beans/InsertBean.hbm.xml"/>


You can also try to replace the \ with a /.

<mapping resource="LuceneApplication/WEB-INF/classes/InsertBean.hbm.xml"/>


I hope, it helps.

Christopher

Thank you for the reply i have tried it out but it didnt work

Nothing did change? You get the same exception?


Here is my own hibernate.cfg.xml, which works perfectly. Maybe you see some differences which I do not see.



But I think about your problem again. Maybe I find the mistake.

I have another idea.

You write



Correct is name instead of first.



Here is a hmb.xml file from me.

thank you colbertz for your solution i checked my mapping and the path it worked but i am getting this problem also can u help me with this also
