VTL

[Pablo Godoy <pg...@gmail.com>]

Hi all! I'm having troubles to merge a template and its parameters by using
VTL.

I did the next example that I found in the apache site:

Velocity.init();

VelocityContext context = new VelocityContext();
context.put( "name", new String("Velocity") );

Template template = Velocity.getTemplate("mytemplate.vm");

StringWriter sw = new StringWriter();

template.merge( context, sw );


This example, worked ok.

But the problem is that I already have the template contents given by
parameter (I don't need to load the resource from the file system).

What can I do? It's necesary to save the contents into a file, and then load
it doing this?
Velocity.getTemplate("templatePath");

I wouldn't like to do it.

Thanks to all!

Regards!

Yeah, that's the simplest way.  If you run into performance problems
later, you can use the StringResourceLoader to allow you to put
strings into a repository and load templates from there to allow your
app to cache templates and not re-parse them every time.

I finally found it...

I had to do this:

Velocity.evaluate(context, sw, "mystring", templateContents);
