Ok it is fine, one option what i was thinking was to create some
temporary .shp file to be the datastore, but there is some document
that it can contain only one graphic or something. I am not sure what
it means the file format is unknow for me.. I need to be able to draw
points and polygons etc. and i will do graphic tools to draw arrows
etc.

Ok own memory datastore is also just fine, what i want is to commit
the features which are drawn with edit tools to memory datastore, in
my tests i have found that commit happends in case of save, but when
datastore is memory datastore udig offers to write them to disk, and
that is not what i want.. unless i use the temporary .shp which i tell
earlier comment.
Later when user has drawn what he needs, there is some my own export
button to export the features to our own file format.
