note The full stack trace of the root cause is available in the Apache Tomcat/5.0.30 logs.

make sure the resource path to FileToSave.hbm.xml in hibernte.cfg.xml matches the actual location of FileToSave.hbm.xml in the classpath.

Here is my source folders:

quickstart

|__WEB-INF
|
|__classes
|__hibernate.cfg.xml, FileToSave.hbm.xml, Upload.java
|
|__lib
|__(hibernate3.jar, and its dependents)

org.hibernate.MappingException: Could not read mappings from resource: FileToSave.hbm.xml

PLEASE HELP !!!

I don't have any classpath. What is the classpath for this running under Tomcat??

...This is hibernate.cfg.xml file---
<session-factory>
<property name="connection.url">jdbc:mysql://localhost/quickstart</property>
<property name="connection.driver_class">org.gjt.mm.mysql.Driver</property>
<property name="connection.username"></property>
<property name="connection.password"></property>
<property name="connection.pool_size">12</property>
<property name="show_sql">false</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Mapping files -->
<!--mapping resource="Cat.hbm.xml"/-->
<mapping resource="FileToSave.hbm.xml"/>
</session-factory>
</hibernate-configuration>

------------This is FileToSave.hbm.xml-----------
<hibernate-mapping>
<class name="FileToSave" table="FileToSave">
<!-- the unique identifier for the cat -->
<id name="name" type="string" unsaved-value="null">
<column name="NAME" sql-type="char(32)" not-null="true"/>
</id>
<property name="type" type="string" unsaved-value="null">
<column name="TYPE" sql-type="varchar(32)" not-null="true"/>
</property>
<property name="size" type="int"/>
</class>
</hibernate-mapping>

Where is FileToSave.java at?

Make sure that the name attribute in FileToSave.hbm.xml is pointing to where this class is. Something like below.

<class name="org.file.FileToSave" table="filetosave" schema="public">

I meant to say FileToSave.class

Here is my source folders:

quickstart

|__WEB-INF

|__classes
|__hibernate.cfg.xml, FileToSave.hbm.xml, Upload.java, FileToSave.java, Upload.class, FileToSave.class

Does this got anything to do with the location of hibernate3.jar ???

the mapping document is invalid, and I'm quite sure the *full* stack trace will say this. remove @unsaved-value from the property element.

don't worry about the classpath. in tomcat, everything under lib or classes will be magically located by the application. the location of FileToSave.class and FileToSave.hbm.xml are ok, but it is probably move all of your classes out of the default package (put org.foo.whatever in front of them).
