MappingInfoNotFoundException for embedded class

Question

The following stack trace appears in my log file when attemping to create
a new User object. User has an embedded Password object. Interestingly
enough, the record, including the embedded password, makes it into the
database. This leads me to believe that this may be a bug.

The User object has a member of type Password called password. The
Password class has a String called password.
Here are the pertinent excerpts from my JDO file:
<class name="Password">
<extension vendor-name="kodo" key="jdbc-use-class-map" value="none" />
</class>
<class objectid-class="UserKey" name="User">
<field name="password" embedded="true" />
</class>
And from my mapping XML file:
<class name="User">
<field name="password">
<jdbc-field-map type="embedded" null-ind-column="password"
synthetic="false">
<field name="password">
<jdbc-field-map type="value" column="password" />
</field>
</jdbc-field-map>
</field>
</class>

Correction: Section 7.8.6 of the Developer's Guide. Example 7.27.

Thanks for the report. Did you ever run the mappingtool's refresh action
on the Password type? Even though you correctly added
jdbc-use-class-map="none" to your metadata, the mapping tool still needs
to be run on the class and a .mapping file generated (the mapping file
will just record a class-map type of "none"). We'll try to smooth this
out in the future.
I have not run the mappingtool, however I don't have a schema file. I
created the tables, the JDO file, and the XML mapping file by hand. Do I
really need to run this tool? Does it modify Password.class? I am going
off the example in section 7.27 in the Developer's Guide. Is the example
in this section correct and complete?
