Set database dictionary in Mappingtool Ant Task

Question

Hi,
I'm sure I'm not the only person that uses the MappingTool Ant task to
create SQL DDL, so why isn't there a way to tell it to use the correct
database
dictionary? When I run the ant task, the SQL producted is incorrect for my
database type.
I've checked the MappingTookTask.java file and I can that
JDBCConfiguration has a setter method to set the dictionary, but I can't
see how I would add this as a parameter to my Ant Task.
I've added
kodo.jdbc.DBDictionary=postgres
to my kodo.properties file but this doesn't seem to be used by the ant
task.
So for the momement I'm falling back on a sed script to correct the SQL
(i.e. int8(8) to int8, etc), but this is hardly ideal.
Thanks,
Andy.

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.
