Re: RE: [xdoclet-user] Transfering data to the velocity script

[karthik Guru]

I believe velocity tools is like any other class and just needs to be instantiated and added to the context to use it. If you want to use one of the velocity tools in the project , place it in the class path and then can you verify if the following helps?

protected void populateContextMap(Map map) {
        super.populateContextMap(map);
        map.put("date",new
                org.apache.velocity.tools.generic.DateTool());

}

You might have to do the same for every velocity-tools you plan to use - ie look for the actual implementation class and add it to the context.
