Mappingtool Ant task classpath errors

Question

Hello,
     I'm trying to use the mappingtool in my build file, but I'm getting a
ClassNotFoundException:
[mappingtool] java.lang.ClassNotFoundException:

When I set kodo.properties to db MappingFactory, I do not get this
error. However, when I set kodo.properties to file MappingFactory, I get
this error. Nothing else is different.
I've checked several times to make sure the class path setting is correct:
<!-- run mappingtool -->
<mappingtool action="refresh">
     <classpath>
          <path refid="jdo.classpath"/>
          <pathelement location="${build.classes.dir}"/>
     </classpath>
     <fileset dir="${build.classes.dir}" includes="package.jdo"/>
     <config propertiesFile="${kodo.home}/kodo.properties"/>
</mappingtool>
and my file is in ${build.classes.dir}
Also note that the jdoc task works fine with this same classpath, so
this seems like an issue with mappingtool.
See my other mappingtool post for similar errors, maybe related.

Could it be that Kodo is in fact using the right dictionary, but is just
issuing bad SQL? What version of Kodo are you using? And what exactly
are the symptoms of the problem? The use of type names like int8(8)?
Is that generated for an existing database column, or a new one Kodo is
creating?Something strange is happening because my other Ant tasks, including a
mapping tool task that creates the database tables works fine.
Here is how I call the task that creates the schema file -
<pre>
<mappingToolTask action="refresh" sqlfile="${sql.schema.file}"
schemaaction="build">
<fileset dir="${project.src.dir}">
<include name="**/*.jdo" />
</fileset>
</mappingToolTask>
</pre>
Here is how I call the task that creates the database tables -
<pre>
<mappingToolTask action="${param.action}">
<fileset dir="${project.src.dir}">
<include name="**/*.jdo" />
</fileset>
</mappingToolTask>
</pre>
As you can see only only differnce between the two tasks is the sqlfile
and schemaaction properties - it is as if the code that writes the schema
file does use the same dictionary logic as when the database tables are
created.
Th error manifests itself as incorrect data types (for PostgreSQL). I get
int(8) instead of int8, etc. Currently I correct this as follows -
line = line.replaceAll("int8\\(8\\)","int8");
line = line.replaceAll("int4\\(4\\)","int4");
line = line.replaceAll("timestamp\\(8\\)","timestamp");
line = line.replaceAll("bigserial\\(8\\)","bigserial");
line = line.replaceAll("bool\\(1\\)","boolean");
line = line.replaceAll("text\\(-1\\)","text");
line = line.replaceAll("float8\\(8\\)","float8");
I'm using 3.3.4.
