Can't anyone help me with it?? Maybe, I've described my question bad...
DocumentCreator calls NewBlogEntryCreator.create with empty"parameters" param:

            creator.create(
                new File(doctypesDirectory, "samples"),
                new File(authoringDirectory, parentId),
                childId,
                childType,
                childName,
                language,
                Collections.EMPTY_MAP);

NewBlogEntryCreator.create is inherited from DefaultCreator:
    public void create(
        File samplesDir,
        File parentDir,
        String childId,
        short childType,
        String childName,
        String language,
        Map parameters) {
...
        // transform the xml if needed
        log.debug("transform sample file: ");
        transformXML(doc, id, childType, childName, parameters);
...
}

And NewBlogEntryCreator.transformXML uses parameters as non-empty map:
        // Replace title
        du.setElementValue(doc, "/echo:entry/echo:title",
(String)parameters.get("title"));

I can't understand, where empty parameters map is replaced with
request parameters map but I need the same trick in my app.
Thanks.
